Randomized Controlled Trial Comparative Study Clinical TrialTopical anesthesia with eutetic mixture of local anesthetics cream in vasectomy: 2 randomized trials.
Two paired randomized trials testing topical anesthesia with a eutetic mixture of local anesthetics (EMLA cream*) in vasectomy were performed. In 1 trial EMLA cream was applied on 1 side of the scrotum, while infiltration anesthesia into the skin and subcutaneous tissue with mepivacaine was used on the contralateral side. All but 1 of the 13 patients (p less than 0.05) preferred infiltration anesthesia because of pain as the incision reached the subcutaneous tissue. ⋯ There was significantly less pain on the sides with the anesthetic cream (p less than 0.001). Many patients would pay the price of the cream. In conclusion, EMLA cream cannot replace but it can supplement infiltration anesthesia during vasectomy.

Randomized Controlled Trial Clinical TrialMetoclopramide: an analgesic adjunct to patient-controlled analgesia.
This randomized, double-blind trial evaluated the effect of metoclopramide on the pain and analgesic requirements associated with prostaglandin-induced labor for second-trimester termination of pregnancy. After receiving intrauterine prostaglandin, seven women were given intravenous metoclopramide (10 mg), and eight received saline, concurrent with initiation of patient controlled analgesia (PCA). ⋯ We conclude that a single dose of metoclopramide reduces the pain and PCA-morphine requirements of patients undergoing prostaglandin-induced labor and may facilitate passage of the fetus. Metoclopramide may have a similar application in treating other types of gynecologic pain.

Randomized Controlled Trial Comparative Study Clinical TrialOpioid supplementation to propofol anaesthesia for outpatient abortion: a comparison between alfentanil, fentanyl and placebo.
One hundred and sixty-four patients scheduled for elective termination of pregnancy under general anaesthesia were randomly assigned to receive one of three different supplements to propofol and oxygen in nitrous oxide anaesthesia: 0.1 mg fentanyl, 0.5 mg alfentanil or placebo. Postoperative pain and nausea, as well as complications during anaesthesia were studied. There were no differences in complications or complaints by surgeons during anaesthesia, and no patient in any group reacted unsatisfactorily to surgery. ⋯ In conclusion, opioid supplementation lowered the amount of propofol needed for anaesthesia. Alfentanil 0.5 mg did not improve the postoperative course. Fentanyl 0.1 mg decreased the frequency of postoperative pain without increasing the time to hospital discharge.

Randomized Controlled Trial Comparative Study Clinical Trial
Nausea and vomiting after termination of pregnancy as day surgery cases: comparison of 3 different doses of droperidol and metoclopramide as anti-emetic prophylaxis.
Frequency of nausea and vomiting following day case termination of pregnancy was found to be rather high (42%) without anti-emetic prophylaxis. Droperidol in doses of 2.5 mg, 1.25 mg and 0.25 mg were found to be equally effective as prophylactic anti-emetic, but not metoclopramide 10 mg. This study confirms that low dose droperidol 0.25 mg is effective as a prophylactic anti-emetic, without any delay in immediate recovery and hence suitable for day surgery cases.

Randomized Controlled Trial Clinical Trial
Effect of epinephrine on intrathecal fentanyl analgesia in patients undergoing postpartum tubal ligation.
Eighty women receiving spinal anesthesia for postpartum tubal ligation were entered into a double-blind, randomized protocol studying the effects of epinephrine on intrathecal fentanyl-induced postoperative analgesia. All patients received 70 mg hyperbaric lidocaine with either 0.2 mg epinephrine (LE), 10 micrograms fentanyl (LF), epinephrine and fentanyl (LFE), or 0.4 ml saline (L). ⋯ The simultaneous administration of epinephrine and fentanyl prolonged the duration of complete analgesia (137 +/- 47 min (LFE); 76 +/- 32 min (LE); 85 +/- 44 min (LF); 65 +/- 36 min (L)) and the duration of effective analgesia (562 +/- 504 min (LFE); 227 +/- 201 min (LE); 203 +/- 178 min (LF); 198 +/- 342 min (L)). Administration of epinephrine decreased the incidence of pruritus associated with intrathecal fentanyl (1/18 (LFE); 1/21 (LE); 8/19 (LF); 2/19 (L)).
