Low dose epidural bupivacaine/fentanyl infusion does not mask uterine rupture.
A patient is described in whom the symptoms and signs of uterine rupture were not masked by combined spinal epidural analgesia with an epidural infusion of 0.1% bupivacaine and 1.5 microg ml(-l) fentanyl. Early recognition of the dehiscence of a previous caesarean section scar resulted in an excellent neonatal and maternal outcome.

Clinical Trial Controlled Clinical TrialPerioperative analgesia for caesarean section: comparison of intrathecal morphine and fentanyl alone or in combination.
In a double-blind placebo-controlled trial we compared perioperative pain relief using different intrathecal opioid regimens given with bupivacaine during spinal anaesthesia for elective caesarean section. One hundred and sixteen patients undergoing elective caesarean section were divided into four groups (A, B, C, D) of 29 patients each. In addition to hyperbaric bupivacaine (12-14 mg), group A received 1 ml of normal saline, group B 25 microg of fentanyl, group C 100 microg of morphine, and group D received both fentanyl 25 microg and morphine 100 microg intrathecally. ⋯ The use of the opioids in association, however, was found to increase the incidence of side-effects. The quality of postoperative analgesia with fentanyl, when used alone, was found to be inferior to that with morphine. The combination of opioids offered no advantage over morphine alone.

Spinal anesthesia versus intravenous sedation for transvaginal oocyte retrieval: reproductive outcome, side-effects and recovery profiles.
Transvaginal ultrasonically guided oocyte retrieval is commonly performed as part of in vitro fertilization efforts. The impact of anesthetic management on patient outcome from this procedure has not been well characterized. At our institution, patients are offered a choice of either heavy intravenous sedation or spinal anesthesia with minimal or no sedatives. ⋯ The intravenous sedation group required a significantly longer period until recovery room discharge criteria were met (P = 0.03), and were more likely to have postoperative emetic episodes (46% versus 6% in the spinal anesthesia group: P < 0.01). Two unplanned hospital admissions occurred in the intravenous sedation group: both were related to uncontrolled nausea and vomiting. We conclude that spinal anesthesia may have advantages over intravenous sedation for oocyte retrieval.
