The early recovery of cognitive function after total-hip replacement under hypotensive epidural anesthesia.
Recovery of cognitive function immediately after major surgery has not been previously reported, partly because of residual drug effects and pain. ⋯ The Stroop Color and Word Test can be used to assess change in cognitive function immediately after surgery. Total-hip replacement performed under regional anesthesia with propofol sedation enables recovery of cognitive function (as assessed by SCWT) 2 hours after surgery.

ReviewNo evidence for analgesic effect of intra-articular morphine after knee arthroscopy: a qualitative systematic review.
Intra-articular (IA) injection of morphine has been the subject of many randomized clinical trials (RCTs). Both negative and positive results have been obtained in trials with a preemptive design, and the question of efficacy remains unresolved. Recent RCTs on patients whose inclusion was delayed until a baseline pain of at least moderate intensity was documented have illuminated the pitfalls of IA analgesic trials. Previously published systematic reviews may have included flawed RCTs in the analyses. ⋯ There are few well-controlled RCTs on IA morphine, and the negative trials of higher quality counter the evidence from the numerous positive ones of lower quality. The quality of most published trials is poor, and performing meta-analysis on these data is not meaningful. Properly controlled trials, in which early postoperative pain intensity is documented, suggest that there is no added analgesic effect of IA morphine compared with saline alone.

Randomized Controlled Trial Comparative Study Clinical TrialSpinal 2-chloroprocaine: minimum effective dose.
Recent studies using preservative-free 2-chloroprocaine (2-CP) for spinal anesthesia have shown it to be a reliable short-acting agent in the 30-mg to 60-mg range. Investigations of doses below this range have not been performed. ⋯ Spinal 2-CP 40 mg and 60 mg provide rapid and reliable sensory and motor block. Although the 20-mg and 30-mg doses can produce sensory anesthesia adequate for brief surgical procedures, less motor block and some sacral sparing should be anticipated. Because the 10-mg dose produces only brief and inconsistent sensory anesthesia, it can be considered a no-effect dose.

Randomized Controlled Trial Comparative Study Clinical TrialAnesthetic techniques and postoperative emesis in pediatric strabismus surgery.
Postoperative emesis after pediatric strabismus surgery continues to be a problem, despite the use of antiemetics. The purpose of this study was to identify an anesthetic technique associated with the lowest incidence of vomiting after pediatric strabismus surgery. ⋯ Among the three techniques, peribulbar block with propofol-based anesthesia is the technique with the lowest incidence of postoperative emesis. Fentanyl-propofol is an equally acceptable alternative; however, meperidine-propofol is associated with a high incidence of postoperative emesis.
