Clinical TrialCompartment block for foot surgery. A new approach to tibial nerve and common peroneal nerve block.
The concept of single injections of local anesthetics into fascial compartments was pioneered by Winnie in reports on paravascular techniques. Winnie described an axillary approach for brachial plexus block and the inguinal route for lumbar plexus block. The compartmental principle can, with advantage, be extended to more peripheral anesthesia of the tibial and common peroneal nerves by the use of osteofascial compartments in the leg. ⋯ Further studies of compartmental anesthesia for other nerve trunks and plexuses may be of value.

Comparative Study Clinical TrialA retrospective comparison of interscalene block and general anesthesia for ambulatory surgery shoulder arthroscopy.
An increasing percentage of all surgery is performed in an ambulatory surgery setting. Concurrently, arthroscopy of the shoulder joint has allowed definitive repair of shoulder pathology to occur in this environment. This study was designed to ascertain whether interscalene block is reliable and efficient for use in same-day surgery compared with general anesthesia for shoulder arthroscopy. ⋯ Interscalene block should be considered as a viable alternative to general anesthesia for shoulder arthroscopy in ambulatory surgery patients.

Randomized Controlled Trial Clinical TrialAddition of clonidine to epidural morphine enhances postoperative analgesia after cesarean delivery.
The randomized, double-blind, dose-response study was designed to evaluate the effects of the addition of clonidine to epidural morphine on postoperative analgesia and side effects in patients undergoing cesarean delivery. ⋯ A low dose of clonidine such as 75 micrograms doubled the duration of analgesia produced by 2 mg of morphine and a dose of 150 micrograms further increased the duration of postoperative complete analgesia without increasing the incidence of side effects. The morphine requirements during the postoperative period (36 hours) was greatly reduced by the addition of clonidine to the analgesic epidural mixture.

Randomized Controlled Trial Clinical TrialContinuous high thoracic epidural administration of morphine with bupivacaine after thoracotomy.
The purpose of the study is to determine the ideal concentration of morphine when given with bupivacaine as a continuous high thoracic epidural infusion for postthoracotomy pain. ⋯ Continuous high thoracic epidural administration 0.2 mg/mL morphine in bupivacaine 0.75% at an infusion rate of 0.8 mL/hr with a loading dose of 1 mg morphine is an effective dose for postthoracotomy pain relief in rest, and more important, during exercise.
