Comparative Study Clinical Trial Controlled Clinical TrialInfluence of bupivacaine as an adjuvant to epidural morphine for analgesia after cesarean section.
The effect of the addition of bupivacaine to epidural morphine (EM) on postoperative analgesia was evaluated in 150 patients after cesarean section performed under epidural anesthesia with carbonated lidocaine. Fifty patients received 3 mg EM without bupivacaine, 50 received 3 mg EM with 0.125% bupivacaine, 25 received 5 mg EM without bupivacaine, and 25 patients received 5 mg EM with 0.125% bupivacaine. ⋯ The addition of bupivacaine did not affect the quality or duration of analgesia afforded by EM and did not influence the incidence or severity of side effects. Furthermore, there was no statistically significant difference in the analgesia obtained by patients receiving 3- and 5-mg doses of EM with or without bupivacaine.

Randomized Controlled Trial Comparative Study Clinical Trial
Double-blind parallel comparison of ketoprofen (Orudis), acetaminophen plus codeine, and placebo in postoperative pain.
One hundred sixty-one patients with postoperative pain were treated at a single center in a double-blind, randomized, parallel study designed to compare the efficacy and safety of single oral doses of ketoprofen (50 and 150 mg), an acetaminophen (650 mg) plus codeine (60 mg) combination, and placebo. From 1 through 4 hours after administration of the study drugs, the mean summed pain intensity difference (SPID) and time-weighted total pain relief (TOPAR) scores for the three active treatments generally were significantly (P less than 0.05) higher than those for placebo but not significantly different from each other. ⋯ As a result of a higher frequency of somnolence, there was a significantly (P less than 0.05) greater incidence of central nervous system adverse drug reactions among patients treated with acetaminophen plus codeine than among those treated with 150 mg of ketoprofen. These results indicate that the analgesic efficacy of both 50 and 150 mg doses of ketoprofen equals that of acetaminophen 650 mg plus codeine 60 mg and the duration of the analgesic effect of ketoprofen is significantly longer.

Randomized Controlled Trial Clinical Trial
[Complaints in the postoperative phase related to anesthetics].
In two prospective, randomized studies the frequency of headache, nausea, vomiting, and analgesic requirement during the first postoperative 24 h was observed in order to study differences between the sexes and the inhalation anesthetics halothane, enflurane, isoflurane, or balanced anesthesia with enflurane/alfentanil. Nausea and vomiting were more frequent after enflurane than after halothane or isoflurane. There was no significant difference between anesthetics and frequency of headache, but there were significant differences in postoperative analgesic requirements which were highest after halothane and lowest after isoflurane. ⋯ The second study indicated that balanced anesthesia did not reduce the analgesic requirement compared to enflurane without alfentanil, but lead to a higher incidence of vomiting. After premedication with flunitrazepam and atropine and combined with 70% N2O/30% O2, isoflurane was the most favorable anesthetic agent with regard to the parameters studied. Balanced anesthesia with enflurane/alfentanil did not show any advantages for patients in the postoperative phase under the given conditions.
