RATIONALE Although lower-extremity surgeries are mainly performed under general or central neuraxial anesthesia, ultrasound-guided peripheral nerve block (PNB) can be a good alternative, especially for patients who require continuous anticoagulation treatment and present with poor cardiovascular conditions. PATIENTS CONCERNS The patient required continuous anticoagulation treatment due to the...

BACKGROUND Infusion of local anaesthetic through femoral and sciatic catheters is an accepted method of providing pain relief after knee arthroplasty. However, the minimum effective concentration of perineural local anaesthetics is not known. METHODS Twenty-four patients received femoral and sciatic perineural infusions of levobupivacaine in order to prevent pain relief after total knee arthr...

Peripheral nerve blocks are becoming increasingly popular for perioperative use as anesthetics and analgesics in small animals. This prospective study was performed to investigate the duration of motor and sensory blockade following use of bupivacaine for ultrasound-guided femoral and sciatic nerve blocks in dogs and to measure the plasma concentrations of bupivacaine that result from these pro...

BACKGROUND AND OBJECTIVES There are several methods to locate the femoral nerve in the perivascular inguinal space, being the most common the use of a peripheral nerve stimulator. This study aimed at evaluating femoral nerve block performed with peripheral nerve stimulator as compared to the loss of resistance to air technique, both by single injection or with catheter insertion. METHODS Sixt...

Introduction/Purpose To determine the location of rectus femoris (RF) motor branch nerve, as well its coordinates with reference to anatomical and ultrasound landmarks. Methods Thirty chronic stroke patients stiff knee gait (SKG) RF hyperactivity were included. The nerve muscle was identified medially vertical line from anterior superior iliac spine midpoint margin patella (line AP) vertically ...

BACKGROUND Knee arthroplasty leads to postoperative pain. This study compares analgesia and postoperative bleeding achieved by intrathecal morphine with a continuous femoral plus single-shot sciatic nerve block. METHODS A randomized non-blinded clinical trial enrolled patients aged over 18 years old, ASA I to III who underwent total knee arthroplasty. All patients underwent spinal anesthesia ...

The purpose of this study was to investigate the efficacy of femoral nerve blocks in patients with fractures of the neck of the femur. Thirty-six patients with femoral neck fractures attending the accident department over a three month period received femoral blocks from one of the two authors. The effect of the block was assessed both subjectively and objectively. Thirty patients reported a wo...
