INTRODUCTION
Regional anaesthesia is a vital component of modern trauma and orthopaedic practices. It disrupts the nociceptive pathways at different sites, providing surgical anaesthesia or postoperative analgesia, or both. One of its advantages is the role it plays in developing a perioperative framework that takes into account not only the intensity of pain but also its physiological basis, requirements of surgery, the necessity of early mobilization, and the objectives of recovery.
Patients with traumatic and orthopaedic conditions are very diverse – they may have different types of fractures, soft-tissue traumas, some diseases of the joints, suffered multiple traumas, undergone revision of joints, or have other complex disease combinations. Therefore, the method should be chosen based on the topography of pain, the type of surgery to be performed, urgency, anticoagulant drugs taken, presence of respiratory and neurological disorders, and possibilities of postoperative monitoring.
All methods such as peripheral nerve blocks, neuraxial techniques, and fascial plane blocks have their own specific features and limitations. For upper limbs some brachial plexus approaches may be used while various types of nerve block might be used for surgical interventions in the lower extremities. Spinal and epidural anaesthesia methods are still valuable in certain cases, but their application requires special attention to the haemodynamic consequences and bleeding risks.
OBJECTIVE
The primary objective of this article is to provide a clinically oriented overview of regional anaesthesia in trauma and orthopaedic surgery. It examines how regional techniques can be selected and applied across emergency and elective practice while maintaining attention to patient safety, surgical requirements, and postoperative recovery.
METHODOLOGY
This article offers a comprehensive narrative academic review of regional anaesthesia in trauma and orthopaedic surgery. Narrative exploration was chosen for this topic because of its complexity and the variety of aspects associated with the topic which are too multi-faceted to be understood through narrow pathophysiological comparison.
The construction of the review has been divided into five clinical domains which include: perioperative context and patient assessment; techniques of regional anaesthesia; indications for regional anaesthesia in trauma and elective orthopaedic surgery; complications and risk management issues related to its use; and future of evidence-based practice.
The relevant literature which is required for obtaining conclusions from the formal version of the article must include clinical guidelines, systematic reviews, randomised studies, observational studies, literature related to drug safety and expert consensus papers. The literature examined must be characterised by clear description of population under study, interventions, comparison group wherever possible, outcomes and their limitations.
Evidence must be interpreted in compliance with the problem. Efficacy studies cannot prove long-term functional gain, while evidence gathered from elective surgery cannot be applied to trauma treatment. Moreover, technical success rate must be compared to outcomes that relate to patients’ concerns, like pain relief, adverse events, mobility, rehabilitation and satisfaction with treatment.
RESULTS
The review framework describes regional anaesthesia as a category of procedures whose success will depend on anatomical issues and surgical considerations. It is not possible to choose one procedure for all cases of trauma and orthopaedic patients. Instead, one needs to combine anatomical details, period of pain, need for anaesthesia, and the type of rehabilitation that is anticipated after the surgery in order to create a proper plan.
In the upper limb procedures, the regional anaesthesia can range from proximal brachial plexus nerve blocks to selective nerve blocks. When choosing a technique, the anaesthetist should take into account the place of surgery, type of anaesthesia needed, breathing issues, pre-existing neurological disorders, and decide whether it is necessary to preserve the ability to move outside the surgery site. The block chosen for the surgery should also comply with surgical positioning and time of the surgery.
In the lower limb trauma and surgery, one should think of using femoral, sciatic nerve, adductor canal, fascia iliaca, lumbar plexus blocks and similar types of nerve blocks depending on the type of surgery. The main question is whether total anaesthesia can be useful or would create challenges. One has to evaluate whether the effect of anaesthesia is consistent with the potential risks associated with it.
Neuraxial methods are used in some cases of lower limbs and major orthopaedic surgery. However, prior to the use of these methodologies the physician has to assess some factors, such as the amount of blood in circulation, anticoagulant therapy, risk of infections, neurological disorders, post-surgical observation.
One important aspect of the mentioned types of regional anaesthesia is that they can be used to cover multiple types of surgical operations. Careful assessment of the patient, ultrasound-guided needle placement and sufficient amount of medication administered will ensure the success of the surgery.
Clinical Context and Scope
Role in Perioperative Trauma and Orthopaedic Care
The use of regional anaesthesia is very widespread throughout the process of receiving trauma and orthopaedic treatment. During the initial consultation, surgery, and post-operative rehabilitation phases, it becomes clear that the primary aim of the application of regional anaesthesia is to achieve local pain relief with minimum use of painkillers. The need to consider the use of regional anaesthesia rises especially when it comes to patients with limited reserve owing to inappropriate functioning of their respiratory system, kidneys, cognitive ability, or hemodynamics issues1.
In acute traumatic cases, too much pain can prevent doctors from carrying out different actions, such as examining the patient and conducting imaging procedures. Hence, appropriate choice of regional anaesthesia technique can allow for other procedures to be carried out rather than only assisting during the surgery itself, as in the case with the application of peripheral nerve blocks to relieve pain from hip fractures and help position a patient for spinal anaesthesia1.
Regional anaesthesia can be seen as one of the elements of the innovative multimodal analgesia. Among the succeeding methods of treatment, one can use paracetamol, anti-inflammatory agents when it is appropriate, opioids for temporary pain relief, and non-drug treatment options. However, the main challenge is not only overcoming the necessity of using an opioid but also ensuring sufficient pain relief for the patient1.
The use of regional anaesthesia will be different according to various clinical situations. For instance, in elective surgeries, the major objectives would be to provide predictable pain relief so that a patient can go through rehabilitation and get discharged, while in surgeries dealing with accidents the priority would be given to immediate anaesthesia and altered processes within the body, as well as a need for quick assessment1.
Before one carries out the block, it is important to take the entire recovery path into consideration. Regional anaesthesia should be properly planned in cooperation with doctors, nurses, physiotherapists, and the patient.
Patient Assessment and Block Selection
Before the procedure begins, it is essential to confirm the diagnosis along with the goal of the procedure and how the block will be used. The anaesthetist needs to determine what purpose the block will serve- whether it will be for surgical anaesthesia, postoperative pain control or as a step toward definitive treatment. The anticipated character of the pain needs to be assessed and matched with the anatomy that the proposed approach addresses1.
Medical history needs to show any issues with the heart or respiratory system, kidney or liver problems, infections, allergies, and factors that might affect the effectiveness of the local anesthetic or increase risks related to the procedure. Other points that need to be recorded are any issues due to maturity level, cognitive disorder, chronic pain, any previous use of opioids, and any other issues that would prevent getting informed permission from the patient1.
Neuro examination is especially vital when it comes to trauma patients and patients suffering from diabetic neuropathy or radiculopathy or people with a previous history of peripheral nerve injury. Thus it might be a good idea to assess how an injury affected sensory and motor functions before surgery happens.
Another aspect that needs to get special attention is the need to stop using anticoagulants and antiplatelet drugs for a period of time before the nerve block. The decision should be based on what medication is taken and when it was taken last time1.
Consent needs to inform the patient whether there are any benefits of the drug, if it works well enough and to tell how long it usually takes for the drug to work.
Regional Anaesthesia Techniques:
Upper-Limb and Lower-Limb Nerve Blocks:
Upper-limb regional anaesthesia is mainly based on blocking the brachial plexus or commonly on selective blocking at the level of terminal nerves. Interscalene, supraclavicular and infraclavicular blocks and approaches thru axillary nerves provide different anaesthesia effects and vary based on the site of the surgery. In the case of distal surgical procedures, the technique of selective blocking of median, ulnar and radial nerves or digit blocks can be the most suitable option to preserve the motor function in the upper part of the body2.
Interscalene approach provides good results for pain treatment after shoulder surgery, although the influence of this technique on the phrenic nerve had to be taken into consideration in the case of patients suffering from serious respiratory pathologies. The results of studies proved that a distal junction approach which uses lower volume of anaesthesia has better outcome than intra brachial plexus block and allows to maintain respiratory functions, while keeping most probable benefits of the application of this technique2.
For lower limb surgery the choice of block mostly depends on the place where pain is coming from. There are regular femoral and fascia iliaca blocks used in cases of injury on the level of hip and upper region of the femur, while in case of knee or lower leg surgery there are applied surgical sciatic and popliteal nerve blocks or adductor canal and distal blocks2.
The main problem occurring after surgery of the knee is related to motor function preservation. Using the adductor canal or saphenous nerve technique provides adequate analgesia and better preservation of quadriceps motor function than while using femoral blockade technique. The study provides conclusions that saphenous motor-sparing techniques are more useful than femoral blocks during mobility as femoral blockade technique leads to fall incidents after surgery2.
In the process of selecting a block it is important to pay attention to incomplete sensory blocking. No type of peripheral blockade may in some cases cover pain given by various sources during surgical procedure, including surgical site, tourniquet pain, pain from deep joint structure and pain in the bones due to the changes in the structure. Besides, it is important to inform the patient about the possible need to add additional painkillers and anaesthetics during the procedure2.
Neuraxial anaesthesia and fascia plane blocks:
Spinal anaesthesia has been an accepted method of anaesthesia for certain types of surgery involving the lower limbs. It has the ability to offer good quality anaesthesia for procedures performed below the level of the belly button and can be used along with the sedatives or any other form of pain relief. Its applicability depends on factors like the duration of surgery, position of the patient, the cardiovascular condition, long-clotting complications in the patient, preference of the patient, and possibility of switching to general anaesthesia if necessary2.
Epidural anaesthesia or analgesia has the advantage of controlling the anaesthesia administration, making it useful for some major surgeries or when the anaesthesia is required for a long time after surgery. However, the use of epidurals will involve the management of many complications including hypotension, motor block, retention of urine, catheter placement issues, infection risk and the use of thromboprophylaxis. This means the use of epidurals can be challenging in fast-track rehabilitation programs2.
Neuraxial blockade may not be favourable in the presence of gross hypovolaemia, sepsis, unstable spinal condition, significant bleeding problems, or inability of the patient to cooperate. In trauma emergencies, the speed of fracture repair as well as the requirement for anticoagulation or resuscitative measures would affect the decision on whether neuraxial or general anaesthesia is appropriate2.
Fascia plane blocks have given rise to the development of regional anaesthesia techniques. These techniques deliver the local anaesthetic not directly to the nerve but into a certain anatomical space which it traverses. The main advantages of fascial plane approaches are their easy operability and lesser effect on movement in selective cases, although the effectiveness of pain relief can vary from case to case2.
It would be appropriate to be cautious while using new approaches. The anatomical justification may seem strong, but the amount of evidence available to prove these approaches is not as much as available to confirm the widespread plexus or peripheral nerve blocks. Therefore, the growing use of Greek techniques should be credited with quality control, training, and proof of efficiency2.
Ultrasound and technology optimization:
Ultrasound has changed the field of regional anaesthesia by ensuring that the movements of nerves and blood vessels can be monitored in real time. This means that the clinician is provided with necessary information to be able to choose the safest path for the needle as well as properly monitor the distribution of local anaesthetics. This is especially valuable in trauma cases when the normal anatomy can be disturbed by a number of considerations, including swelling of the patient or presence of immobilizing devices or previous surgeries3.
However, ultrasound usage does not release a medical professional from possible risks. The quality of image can be impacted by the type of patient’s body, appearance of oedema, difficulties with positioning, inexperience of the operator and poor quality of probe contact. Furthermore, the fact that the needle can be seen does not mean that the injection will be performed properly and the spread of local anaesthetics does not assure that the injection was performed properly3.
In practice, some studies proved that ultrasound helps to decrease risks of vascular puncture, systemic toxicity from local anaesthetic agents, cases of pneumothorax and damage caused to phrenic nerve; however, this does not allow making certain conclusions in the relation to cases of permanent damage3.
The optimization of procedure consists of proper monitoring of the patient, keeping IV access where necessary, sterilization of equipment, conducting “time-out” to check the patient‘s identifying data and readiness for possible complications. During the injection of the needle, the operation should be carried out in a careful and determined manner, as well as continue regular use of aspiration and progressive method of injection which means that there should be no situation when unexpected problems arise. The caliber of administering regional anesthesia largely depends on the level of training and experience of the applicator in the field3. It is necessary to acquire knowledge about anatomical structures, possess skills in ultrasound image gaining, have control over the needle, be aware of pharmacotherapy, be capable of identifying cases of ineffective analgesia, and know how to take action when an adverse event occurs. Every medical institution should have a system of supervision, simulation, and analysis of usage of modern technologies in combination with reliable clinical judgment3.
Indications For Regional Anesthesia:
When performing emergency trauma surgery, one must choose methods of anesthesia in such a way that shall not interfere with such processes as resuscitation, imaging, repositioning, and fracture immobilization. The use of regional anesthesia minimizes serious pain in limbs, ensures comfort for the patient during surgery, and reduces the need for the use of systemic analgesics. But it is worth mentioning that regional anesthesia cannot replace evaluation and treatment of trauma4.
An example of the usage of regional anesthetics is a case of hip fracture, where femoral nerve and fascia iliaca blocks can minimize pain. The use of ultrasound-guided blocks has provided positive results in terms of pain and morphine treatment4.
In cases of severe trauma, using regional anesthesia depends on the state of the patient (if the patient is hemodynamically stable, conscious, no possible risk of developing neurological problems, etc.). In addition, it can be for other reasons such as the availability of special equipment or qualified specialists.
Damage-control surgery includes stopping blood loss, ensuring proper sterilization of the operative site, and restoring physiological functions. The main objective of anesthesia in this case is to secure quick resuscitation and effective surgery5.
In case of fractures of the lower leg, denser blocks that last longer than necessary are discouraged. It was agreed that contemporary blocks with minimal concentrations that don’t hinder the diagnostics are permitted provided constant supervision is done5.
Elective Orthopaedic Surgeries:
Elective orthopedic surgeries have a much wider potential for choosing the method of administering anesthesia compared to emergencies in trauma surgery. The clinical staff can cooperate in determining the kind of pain expected, define the method of discharge, assess the capabilities of the patient, and agree on medication to use for pain relief.
For instance, interscalene block is a typical method of pain relief in shoulder surgeries, however, it can cause dysfunction of the diaphragm which may lead to difficulties in the surgery. Specific to institutions and procedures. Peripheral nerve blocks are used in surgeries such as hip arthroplasty, reconstruction of ligaments, and operations on ankles, and complicated foot surgeries. There is an agreement among practitioners in favor of using peripheral nerve blocks in cases where these blocks may be contraindicated, which is dependent on professional and equipment capabilities6.
Just like in the case of elective surgeries, there is a chance of managing rebound pain in advance. Patients should be informed about pain aggravation after the action of the one-time application of the block is over, and taking prescribed analgesics should start according to the developed plan before the numbness ends. Therefore, educating patients about taking medications non-opioid analgesics whenever appropriate and developing realistic expectations are vital for the application of the block6.
Analgesia for Rehabilitation and Recovery:
When assessing the advantages of postoperative analgesia, consideration must be given not just to pain assessment at rest, but also to the patient’s ability to breathe deeply, get sleep, be safe when moving, engage in physiotherapy, and do whatever is necessary. Surgery patients often need to move even though that might provoke pain. Therefore, analgesia should be assessed not only when a patient lies still, but also during movement.
Motor block may either facilitate recovery or hinder it, depending on the operation performed. Deep block can be effective if movement needs to be restricted, but it can be harmful for assessing strength and establishing the possibility of safe ambulation. Meanwhile, motor-sparing technique can allow for starting therapy at an early stage while the patient is still being pain-free and capable of normal movement7.
Fall prevention should be taken into consideration in all cases of lower-limb block procedure. Patients, nurses and physiotherapists should always realize that pain absence doesn’t necessarily indicate good coordination or normal perception. To ensure safe ambulation, coordination assistance will be required till there is supporting motor function7.
The use of continuous peripheral nerve catheters can significantly extend analgesic effect. Although they can help provide analgesia after complicated procedures, they require additional considerations in terms of pump programming and site complications. In other words, their application is reasonable only if there is good follow-up7.
Planning of rehabilitation should go beyond what happens in hospital. Written instructions must be available, contact numbers must be provided, and there should be a plan on pain control in case the patient is discharged with an uninterrupted infusion device.
Local Anaesthetic Systemic Toxicity and Neurological Injury:
Local anaesthetic systemic toxicity is a rare but perilous complication for regional anaesthesia. It might happen, if there is a late injection of the drug, repeated injections, increased dose, or slow clearance. The degree of risk for individual patients may depend on the patient’s size, age, presence of comorbidities, site of an injection, regional anaesthetic type, etc.
Early signs of toxicity are loss of sensation in the mouth area, presence of phantom sound in the ears, taste of metal, anxiety, dizziness, and disturbances of consciousness. More severe cases may also lead to seizures, arrhythmia, disability, and cardiac arrest. Thus, every site where a regional block is performed should have the necessary tools at hand and trained staff ready to deal with the case.
Risk reduction should involve an assessment of the overall dose needed prior to performing the injection. It is necessary to conduct a prompt neurological evaluation and refer the case rather than wait for spontaneous recovery. A recent review shows that the incidence of post-block neurological injury decreases with time from approximately 1% over two weeks to around 3 per 10,000 cases within a year and that these statistics vary depending on the specific technique employed, with ultrasound directly linked to a decrease in the occurrence of certain blocks7.
The risk of bleeding does not depend solely on the use of anticoagulants. Factors such as the class and dosage of antithrombotic agents used as well as the time of their administration, kidney function, platelets count, liver disorders, coagulopathy related to traumatic injuries, depth of the block, site vascularity, and bleeding risk factors play a significant role.
Bleeding in the area of the neuraxis is rare but very serious complication, as hematoma can generate pressure on the spinal cord or cauda equina. Severe back pain, motor weakness, sensory impairment, or bladder and bowel disorders following a neuraxial block call for immediate investigation. The pressing nature of potential neurological injury means that a careful chain of escalation should be in place.
The application of deep plexus or deep periphery blocks requires attention to the bleeding risk involved in the use of nerve blocks in the instance of the inability to locate hematoma or apply compression. Risk-benefit ratio assessment must not be disregarded in cases of peripheral blocks usage5.
The infections would occur as a result of insufficient preparation of skin for application of block or application of contaminated equipment or frequent manipulations with needles or prolonged use of the catheter device. Although severe infections are uncommon, the procedure should be performed according to the rules of strict aseptic techniques. The condition of the catheter site must be frequently assessed and observed for infection symptoms.
Hemodynamic complications should occur in the case of the neuraxial sympathetic block applied to patients suffering from hypovolemia or sepsis or patients with limited autonomic reserves. Some preventive measures must be considered here, including prior to procedure assessment of the patient, careful dosing and monitoring of the patient as well as adequate treatment of hypotension.
Falling, Compartment Syndrome and Diagnosis:
Falling is probably a preventable complication of regional anesthesia of the lower part of the body. Sensory loss, weakness of the quadriceps muscle, impaired proprioception, and use of sedatives give rise to a possibility of falling any time while being aware that any of these factors could be not harmful on its own.
Patients at risk for developing acute compartment syndrome should proceed with caution during the planning of analgesia application. Compartment syndrome is treated as an urgent surgical condition arising from increased tissue pressure, which entails suboptimal perfusion, and potential irreversible damage to the muscles and nerves. Immediate clinical evaluation is necessary if there is an absence of disproportionate pain, an urgent need for an increase in the dose of analgesics, the passive stretching of the patient, changes in sensation in the compartment, or tightness in the compartment5.
The application of regional anesthesia should not be regarded as confirmation or disproof of compartment syndrome. The question is what the application of the given technique will mean for the patient with regard to any new symptoms experienced or the experience of pain. Acute pain is an important clinical aspect even when a regional block has apparently been performed correctly. When this occurs, it should not simply be attributed to issues with the block, anxiety or normal postoperative pain- this can be especially significant following tibial, forearm, and similar accidents that are deemed dangerous. In fact, such pain can indicate developing compartment syndrome, blood supply reduction, excessive pressure due to the cast, infection, or some other complication of surgery.
Safety of diagnosis alone is a joint responsibility of the healthcare professionals. On this basis, the surgeon has to detect injuries that might require monitoring, while the anaesthetist selects a suitable analgesic method. Nursing staff is responsible for assessment and keeping required records, whereas patients need to know about the warning signs that require urgent medical help.
Evidence Based Decision Making and Future Directions:
Comparative Outcomes and Patients Benefits:
While comparing various types of regional anaesthesia first of all one has to deal with results valuable for the patients. Pain intensity and need of opioids for pain relief are important results, but they cannot reflect the recovery process in full. It is also necessary to analyze functional mobility, sleep disturbances, nausea, respiratory problems, delirium episodes, satisfaction, discharge possibility, chronic pain, and the possibility to return to normal life7.
The strongest evidence concerning certain indications is strengthened by evidence regarding the application of new types of blocks. In a study concerning that, it was shown that the techniques differ widely, however, there is a greater amount of data collected regarding the interscalene block used in case of shoulder surgery and motor-sparing saphenous approaches in case of knee surgery7.
However, based on the data from the studies regarding hip fracture, peripheral nerve blocks provide with better pain results and allow to reduce the amount of opioid medication taken systemically before the operation. A review of the studies conducted has shown that under the use of ultrasound-guided blocks, patients report having lower pain than those who were not given such type of treatment, although there is still low evidence quality7.
Competences Needed for Performing Regional Anaesthesia:
In order to safely perform regional anaesthesia, an organised approach is required. The institution needs to have a clear notion about which block can be performed by whom, what supervision is needed, and what monitoring standards are supposed to be applied. Since these instructions are the same for operations performed in the operating theatre, recovery and emergency departments, as well as block units.
Training in this case will include the knowledge about anatomy with further use of this theoretical knowledge in clinical practice. The goal is to develop patient selection skills, obtain informed consent, maximise ultrasound performance, and handle the required instruments properly8.
Standard procedures can be applied to reduce difficulties encountered during the operation. of the patient, procedure, side, proposed block, anticoagulant status, allergy history, dose calculation, and availability of resuscitation equipment should happen before the needle insertion. Visible marking and active participation by the patient, where possible, provide extra safety from wrong-sided procedures.
The documentation should prove what kind of the block was used; giving consent; neurological findings; type of the block; how it was done; what kind of local anesthetic was used, other drugs or methods; what kind of responses were shown; what is the plan after the procedure. If a catheter type of the block is used, there should be information about the type of infusion8.
Audit and feedback are very important for the improvement of techniques. Services should track blocks by their efficiency, pain level, how new opioids were used, falls, neurological symptoms, toxicosis, and the level of complications.
Many advances have been made regarding the types of techniques. Regional anesthesia has many variants because of a variety of already existing and potential approaches that could be used with anesthesia. However, the main aim is to find out if the new technique brings better results in comparison with simper existing techniques of anesthesia8.
Ultrasound-guided fascial space blocks gained a considerable popularity among experienced specialists in this field. These techniques are of much importance as they are easier to perform and train, in comparison with the already existing nervous blocks. Nevertheless, the exact use of local anesthesia for particular practices and the probable complications while using different local anesthetics are still under question and need further research8.
DISCUSSION
In order to carry out a proper research and analysis in this area, scientist need to stick to certain definitions that talk about the effectiveness of every technique. The increasing number of centers applying this kind of techniques will help to conduct relevant studies on regional anesthesia among patients suffering from different illnesses and having different comorbidities. This concept refers to approaches that may minimize the immediate need for systemic opioids while neuraxial techniques are helpful in some lower-limb surgeries. Fascia plane blocks adds more options whenever a motor-sparing or less invasive approach may be required. However, the overall efficacy of these approaches highly depends on the procedure, timing, local expertise, and characteristics of patients.
The best implementation model in this situation is the multimodal and multidisciplinary one. Regional anesthesia has to be integrated with surgical planning, pharmacological pain relief, thrombosis prevention, nursing observation, physiotherapy, and discharge education. This is especially important in cases where the presence of residual motor impairment, catheter management, anticoagulation, or compartment syndrome observation may affect the safety of the procedure.
The solution to safety issues has to be the organized assessment of the regional techniques instead of avoiding them in all high-risk cases. The aspects that have to be taken into consideration include dose calculation, incremental injections, visualization of the injection using ultrasound, aseptic techniques, laterality verification, recording the neurological data, and readiness to address any toxicity issues that have appeared in this process. In situations when injury is prone to compartment syndrome the prevention protocols have to be agreed upon at the beginning of monitoring.
The research shows that regional anesthesia works well in established orthopedic situation, however, there are still some issues that remain unknown. Trials differ from one another in block technique, comparator, and outcome measurement.
CONCLUSIONS
In conclusion, regional anesthesia is an effective element of trauma and orthopedic perioperative care because it facilitates better pain management and decreases the need for systemic opioids. It is further enhanced by the need for integration into a complete multi-modal approach.
Peripheral nerve blocks, neuraxial anesthesia, and fascia plane techniques should be seen as complementary approaches in order to take into account such factors as surgical anatomy, requirement for motor function preservation, and practical opportunities for postoperative observation and treatment.
In most cases, severe complications, such as local anesthetic toxicity, neurological injuries, bleeding, infection, and hypotension, are rare or preventable.
In trauma, regional analgesia should never delay resuscitation or definitive treatment. In elective orthopedic surgery, it should be combined with enhanced recovery goals and practical plan for mobilization in order to ensure the best results. Dialog between anesthesiologist, surgeons, nursing staff, physiotherapists and patient is vital.
