Patients undergoing lower extremity amputation may have multiple co-morbid conditions like diabetes, cardiovascular, hepatic and renal disorders and are at risk of perioperative mortality and morbidity. Peripheral nerve blocks are associated with minimal haemodynamic changes, improved regional blood flow and are ideal for high risk patients who cannot tolerate slightest attenuation in haemodynamic response. The present report is of a 50-year-old female patient admitted for below knee amputation surgery. Sciatic nerve and lumbar plexus block were the mode of anaesthesia. It was found that regional anaesthesia in the form of nerve block provided adequate anaesthesia and analgesia, provided greater haemodynamic stability and patient safety.

Intraneural Injection

AbstractIntraneural injection of a local anesthetic can damage the nerve, yet it occurs frequently during distal sciatic block with no neurological sequelae. This has led to a controversy about the optimal needle tip placement that results from the particular anatomy of the sciatic nerve with its paraneural sheath.The study population included patients undergoing lower extremity surgery under popliteal sciatic nerve block. Ultrasound-guidance was used to position the needle tip subparaneurally and to monitor the injection of the local anesthetic. Sonography and magnetic resonance imaging were used to assess the extent of the subparaneural injection.Twenty-two patients participated. The median sciatic cross-sectional area increased from 57.8 mm2 pre-block to 110.8 mm2 immediately post-block. An intraneural injection according to the current definition was seen in 21 patients. Two patients had sonographic evidence of an intrafascicular injection, which was confirmed by MRI in one patient (the other patient refused further examinations). No patient reported any neurological symptoms.A subparaneural injection in the popliteal segment of the distal sciatic nerve is actually rarely intraneural, i.e. intrafascicular. This may explain the discrepancy between the conventional sonographic evidence of an intraneural injection and the lack of neurological sequelae.
