Randomized Controlled Trial Comparative Study Clinical Trial
Sciatic nerve blockade improves early postoperative analgesia after open repair of calcaneus fractures.
To determine the effectiveness of analgesia, with or without sciatic nerve blockade, after open repair of calcaneus fracture. ⋯ Sciatic nerve blockade confers significant benefit over morphine alone for analgesia after open repair of calcaneus fractures. Postsurgical sciatic nerve blockade provides the longest possible postoperative block duration.

Influence of sensory and proprioceptive impairment on the development of phantom limb syndrome during regional anesthesia.
The relation between impairment of sensorimotor function and occurrence of phantom limb syndrome (PLS) during regional anesthesia has not been described. This study assessed the temporal relation between PLS and the progression of sensorimotor impairment during placement of a brachial plexus nerve block. ⋯ This study provides a better understanding of the determinants of PLS by showing that the final position of PLS is related both to the abolition of proprioception and the initial position of the anesthetized limb.

Randomized Controlled Trial Comparative Study Clinical Trial
The radial nerve should be blocked before the ulnar nerve during a brachial plexus block at the humeral canal.
The brachial plexus block through the humeral canal as described by Dupré is indicated in hand and forearm surgery. This block requires a multi-stimulation technique that emphasizes the necessity of a rigorous and safe technique. Nerve injury associated with regional anesthesia can entail significant morbidity for patients. Thus, we investigated the brachial block sequence in terms of unintended nerve stimulation as a surrogate of potential nerve injury. ⋯ Our results indicate that the radial nerve should be blocked before the ulnar nerve when performing a brachial plexus block at the humeral canal.

Randomized Controlled Trial Clinical TrialAnalgesia and discharge following preincisional ilioinguinal and iliohypogastric nerve block combined with general or spinal anaesthesia for inguinal herniorrhaphy.
Preincisional ilioinguinal and iliohypogastric nerve block (IINB) reduces postoperative analgesics after inguinal herniorrhaphy. The effect of an IINB on postoperative pain and discharge profile was therefore studied in day-surgery patients undergoing inguinal herniorrhaphy with general or spinal anaesthesia. ⋯ Only a relatively short immediate analgesic benefit could be demonstrated by a combination of IINB with spinal anaesthesia compared with IINB combined with general anaesthesia. The use of general anaesthesia facilitated an earlier postoperative discharge than spinal anaesthesia.

Plasma ropivacaine levels following scalp block for awake craniotomy.
The plasma levels of ropivacaine HCl with 5 mcg/mL epinephrine were measured in 10 patients following scalp blockade for awake craniotomy. A mean dose of 260 mg (3.6 mg/kg) resulted in peak plasma concentrations of 1.5 +/- 0.6 mcg/mL, with a median time to peak plasma concentration of 15 minutes. ⋯ Despite this rapid rise of plasma level, no signs of cardiovascular or central nervous system toxicity were observed. In this group of patients undergoing awake craniotomy for excision of lesions in the eloquent areas of the cerebral cortex, ropivacaine HCl with epinephrine appeared to be a safe and effective local anesthetic agent in the dosages used.
