To estimate the frequency of successful conduction blockade of the femoral, lateral femoral cutaneous, and obturator nerves following a femoral 3-in-1 block. ⋯ The femoral 3-in-1 nerve block does not block the parent trunk of the obturator nerve.

Randomized Controlled Trial Clinical TrialPulmonary function changes during interscalene brachial plexus block: effects of decreasing local anesthetic injection volume.
During interscalene block, ipsilateral hemidiaphragmatic paresis occurred in all patients who received > 34 ml of local anesthetic in the authors' previous studies. This study was done to determine whether diaphragmatic function could be spared by a smaller local anesthetic volume. ⋯ Reducing the volume of local anesthetic to 20 ml did not prevent the 100% incidence of diaphragmatic paresis or significantly lessen the compromise in pulmonary function that had been reported to occur during interscalene brachial plexus anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Combined spinal epidural block versus spinal and epidural block for orthopaedic surgery.
In a controlled study a single segment combined spinal epidural (CSE) block was compared with spinal or epidural block for major orthopaedic surgery. Seventy-five patients, age 52-86 yr, were randomly assigned to receive one of the three blocks. Bupivacaine 0.5% was used for surgical analgesia. ⋯ Perioperative sedatives and concomitant analgesics were required more frequently and in larger doses by the patients undergoing surgery with epidural block (P < 0.05) than with CSE or spinal block. Our study demonstrated that the analgesia after surgery provided by 0.2 and 0.4 mg morphine administered intrathecally was comparable to that provided by 4.0 mg of epidural morphine. It is concluded that the analgesia and surgical conditions provided by the spinal and CSE blocks were similar and were superior to those provided by an epidural block.
