Randomized Controlled Trial Clinical Trial[Brachial plexus block: effect of the addition of sufentanil to local anesthetic mixture on postoperative analgesia duration].
To compare the quality and the duration of analgesia produced by a supraclavicular brachial plexus blockade obtained with a mixture of lidocaine and bupivacaine when supplemented or not with sufentanil. ⋯ Sufentanil added to a mixture of lidocaine and bupivacaine increases twofold the duration of postoperative analgesia following branchial plexus blockade.

Randomized Controlled Trial Comparative Study Clinical Trial
Pain following craniotomy: a preliminary study comparing PCA morphine with intramuscular codeine phosphate.
We have performed a prospective randomised trial of 30 patients undergoing craniotomy to compare intramuscular codeine phosphate with patient-controlled analgesia using morphine 1 mg bolus with a 10-min lockout and no background infusion. For 24 h postoperatively, pain, nausea, Glasgow coma score, respiratory rate and sedation score were assessed. There was a wide variation in the amounts of morphine requested by the patients in the patient-controlled analgesia group in the first 24 h postoperatively (range 2-79 mg, median 17 mg). ⋯ There were no significant differences between the two groups in respect of nausea and vomiting, sedation score or respiratory rate. No major adverse effects were noted in either group. Patient-controlled analgesia with morphine is an alternative to intramuscular codeine phosphate in neurosurgical patients which merits further investigation.

Randomized Controlled Trial Clinical TrialMaternal posture influences the extent of sensory block produced by intrathecal dextrose-free bupivacaine with fentanyl for labor analgesia.
The cephalad extent of sensory block produced by intrathecal (IT) dextrose-free local anesthetics and opioids has been reported to be quite variable. Most reports describing the effects of IT analgesics do not control for patients posture. Because these medications are hypobaric relative to cerebrospinal fluid (CSF), parturients in a sitting position may develop greater cephalad extents of sensory block than those in a lateral position during IT injection. ⋯ Mean cephalad extent of block was greater in the sitting group at 20 and 30 min. When sensory block asymmetry was observed, the extent of block was greater on the nondependent side. Posture during IT injection of this dextrose-free analgesic combination affects extent of sensory block in laboring parturients.

Randomized Controlled Trial Clinical Trial
Pre-operative oral administration of morphine in day-case gynaecological laparoscopy.
The analgesic effect of morphine sulphate 10 mg by mouth given pre-operatively on pain after gynaecological laparoscopy was studied in a randomised, prospective, double-blind, placebo-controlled comparison. Two groups of 56 patients were studied one group undergoing diagnostic laparoscopy and the other laparoscopic sterilisation. ⋯ Morphine premedication did not significantly influence postoperative pain as assessed on a visual analogue scale in either group and postoperative opioid consumption was unaffected. Premedication with morphine 10 mg orally does not significantly decrease pain after day-case gynaecological laparoscopy.

Randomized Controlled Trial Clinical TrialThe safety and efficacy of oral transmucosal fentanyl citrate for preoperative sedation in young children.
Oral transmucosal fentanyl citrate (OTFC) is a labeled preoperative pediatric sedative. Doses greater than 15 micrograms/kg are associated with a high incidence of post-operative nausea and vomiting and occasional respiratory depression. We studied the safety and efficacy of OTFC in children 6 yr old and younger at a dose of 15 micrograms/kg. ⋯ One OTFC patient developed rigidity during induction. Emergence and recovery were not delayed by OTFC despite a 50% incidence of postoperative vomiting. We do not recommend the use of OTFC in a 15 micrograms/kg dose as a routine preoperative sedative in children 6 yr old and younger.
