morphinans and Genital-Diseases--Female

Butorphanol/diazepam was compared with thiopental for induction of anesthesia, and the thiopental-sparing effects of butorphanol/diazepam determined. One hundred women, American Society of Anesthesiology physical status class I, undergoing ambulatory, elective termination of pregnancy were randomized to receive either butorphanol 2 mg plus diazepam 10 mg, or thiopental, until loss of the lid reflex occurred. The butorphanol/diazepam group received supplemental thiopental as necessary to attain adequate induction of anesthesia. The combination of butorphanol and diazepam significantly reduced the thiopental dose required to produce loss of the lid reflex, from 4.2 +/- 0.8 to 0.8 +/- 0.6 mg/kg (p less than 0.005), with 22 percent of the patients not requiring supplemental thiopental. The intraoperative course and anesthetic requirements were similar between the two groups. Lower recovery room rating scale values upon arrival at the recovery room were attributed to significantly higher weight-normalized doses of butorphanol (p = 0.004) and diazepam (p = 0.005). The duration of the recovery room stay was 68.8 +/- 24.9 min for the control group, and 80.8 +/- 29.0 min for the butorphanol/diazepam-treated patients (p = 0.026). There were no clinically significant differences in anesthesia or postanesthesia recovery. The combination of butorphanol and diazepam has a significant thiopental-sparing effect, and is a useful induction technique for short, ambulatory surgical procedures.

In this comparative study in 102 female patients, midazolam or thiopentone was used as the sleep-inducing component in combination anaesthesia. During anaesthesia, three different analgesics: fentanyl, oxycodone and buprenorphine were tested. The sleep-inducing effect of midazolam was clearly slower in onset than that of thiopentone, but in other respects midazolam was a satisfactory inducing agent for general anaesthesia. Patients receiving midazolam and/or buprenorphine needed an additional dose of muscle relaxant less often than those receiving thiopentone and fentanyl or oxycodone. Buprenorphine produced a long postoperative analgesia lasting up to 10 hours, but these patients were also postoperatively drowsier, which gave a lower postanesthetic recovery score.
