Randomized Controlled Trial Clinical Trial
Scopolamine patch reduces postoperative emesis in paediatric patients following strabismus surgery.
Scopolamine patch was evaluated for the prevention of postoperative emesis in 50 children undergoing strabismus surgery. All subjects were premedicated, with none receiving narcotic premedicants. ⋯ Before operation, the subjects were randomly assigned to one of two groups: a treatment group received a scopolamine patch at a dose of either 0.75 mg or 0.375 mg, and a control group received no patch. Both the incidence and frequency of vomiting in the scopolamine-treated group were significantly (P less than 0.05) lower than in the control group.

Randomized Controlled Trial Clinical Trial
Epidural fentanyl does not influence intravenous PCA requirements in the post-caesarean patient.
Forty ASA physical status I or II patients scheduled for elective Caesarean delivery were studied to determine the effect of epidural fentanyl on post-Caesarean delivery analgesic requirements as administered by intravenous patient-controlled analgesia (PCA). Following delivery of the infant, under epidural anaesthesia with lidocaine 2% with 1/200,000 epinephrine, patients were randomly assigned to receive either 10 ml of preservative-free normal saline via the epidural catheter or 100 micrograms of fentanyl with 8 ml preservative-free normal saline in a double-blinded fashion. ⋯ No differences were observed in any values between the groups. It is concluded that a single bolus of epidural fentanyl does not provide an advantage for postoperative pain relief in this patient population.
