Regional anesthesia and anticoagulation

Current Opinion in Anaesthesiology (Impact Factor: 1.98). 10/2004; 17(5):427-433. DOI: 10.1097/00001503-200410000-00013

ABSTRACT

Purpose of review:
Patients receiving perioperative anticoagulation are a challenge for anesthesiologists when regional anesthesia would be a beneficial component of the anesthetic plan. Newly approved antithrombotic drugs maintain the need for updated review articles and recommendations.

Recent findings:
Due to the very low incidence of bleeding complications, guidelines are solely based on retrospective analyses of case reports and pharmacological considerations. Hence, they should not be taken as evidence-based 'cook books'. Recommendations of well established anticoagulants like heparin and non-steroidal antiinflammatory drugs may have a solid basis. However, the lack of data on new antithrombotic drugs including GII/GIIIA antagonists, factor X and thrombin-inhibitors requires a more conservative approach when regional anesthesia is considered. Current literature emphasizes postoperative monitoring; clear recommendations of its performance, however, are missing.

Summary:
Decisions to perform regional anesthesia in patients under anticoagulation should always be made on an individual risk-benefit assessment. A vigilant preoperative evaluation of the patient's medication and physical findings are as important as awareness of postoperative plans for anticoagulation.

    ABSTRACT: Unlike neuraxial anesthesia, performing peripheral nerve blocks in the presence of anticoagulation offers a margin of safety. The catastrophic event appears to be bleeding rather than major neurologic injury. In general, superficial limb blocks are not contraindicated in patients receiving anticoagulation. Deeper blocks such as the posterior lumbar plexus block, especially with the use of continuous catheter technique, necessitate a more prudent approach. Careful risk-to-benefit assessment through thorough preoperative evaluation, awareness of perioperative anticoagulation plans, and good knowledge of drug pharmacology should be applied to individual patients.

    ABSTRACT: Increasing numbers of patients are taking drugs that impair normal coagulation, and this causes concern about the risk of perioperative bleeding events. The anaesthetist is particularly concerned about compressive vertebral canal haematomas, which may occur after spinal or epidural anaesthetic techniques. Fortunately, the risk of this complication is very low. The major risk factors are coagulaopathy or technical difficulties with the block. There is also concern about perineural haematomas, which may be associated with peripheral nerve blocks. This article attempts to put the risks of these complications into context, with reference to different classes of anticoagulant drugs.

    ABSTRACT: Medical and surgical treatment of the trauma patient has evolved in the last decade. Treatment of pain from multiple fractures or injured organs and surgical anesthesia with regional anesthesia techniques have been used to reduce post-traumatic stress disorder and reduce the adverse effects of general anesthesia. Neuraxial blocks and peripheral nerve block techniques should be practiced by trained emergency and operatory room staff. This article reviews recent publications related to the role of regional anesthesia in trauma patients in the prehospital, emergency, and operatory room settings. It also describes indications, limitations, and practical aspects of regional anesthesia.
