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.

Randomized Controlled Trial Comparative Study Clinical TrialSpinal hyperbaric ropivacaine-fentanyl for day-surgery.
Adequate intraoperative analgesia combined with faster mobilization might be achieved by replacing hyperbaric ropivacaine partly with fentanyl. ⋯ Faster mobilization but equal onset and duration of analgesia were achieved with intrathecal hyperbaric ropivacaine 10 mg plus fentanyl 20 microg as compared with hyperbaric ropivacaine 15 mg.
