Thirty-two women underwent major gynaecological surgery with a midazolam-alfentanil total i.v. anaesthetic regimen. Adequacy of anaesthesia was assessed using a "pressure, rate, sweating and tears" (PRST) scoring system in conjunction with the isolated forearm technique (IFT). The IFT revealed that 72% of patients responded during surgery, but none had spontaneous, unprompted postoperative recall for the event. ⋯ Twenty patients, asked specifically during surgery to indicate the presence or absence of pain, experienced pain at some time during their surgical procedure. The PRST score could not be used to predict when a patient was awake. This low-dose i.v. anaesthetic technique cannot be recommended for general use.

Clinical office anesthesia: the use of propofol for the induction and maintenance of general anesthesia.
Ambulatory surgery has become routine for many plastic surgery procedures. Anesthesia techniques including general anesthesia by inhalation and intravenous infusion and the dissociative technique have all been used successfully for outpatient anesthesia. ⋯ We report on our experience with propofol as an induction agent and continuous drip for general anesthesia maintenance in 100 consecutive outpatient, plastic surgery procedures performed in an office facility. Assessment factors were recovery-room time, nausea and vomiting in the recovery room and at home, hallucinations, patients' recollection of anesthesia experience, and overall patient satisfaction.

Randomized Controlled Trial Comparative Study Clinical Trial[Infusion of propofol or closed-circuit isoflurane. A study of cost].
The choice of an anaesthetic agent is influenced by its cost. The use of a circle absorber system decreases the cost of the maintenance of anaesthesia with halogenated agents. Fast recovery and low incidence of postoperative nausea and vomiting are the main advantages of propofol. ⋯ The total cost of anaesthesia included also the recovery room stay. The mean duration of anaesthesia was not significantly different between the two groups (109.4 +/- 7.1 min vs 107.3 +/- 7.3 min group P vs group I). The delay lf recovery (eyes opening) was shorter in the propofol group (14.4 +/- 1.3 min vs 19.4 +/- 1.4 min) as well as the delay of discharge from the recovery room (70 +/- 4 min, vs 82.4 +/- 4.6 min).(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Clinical Trial[Postoperative respiratory depression following ambulatory anesthesia for abortion. Evolution of the ventilatory response to CO2 following the use of propofol alone or in association with different opioids: comparison with midazolam in the same situation].
Sixty patients, undergoing minor gynaecologic procedures, were prospectively enrolled in this randomized study. They were anaesthetized with either propofol or midazolam supplemented or not with fentanyl or alfentanil. ⋯ No respiratory depression was observed when propofol was used alone. By contrast, midazolam alone induced a significant respiratory depression during the first postoperative hour.

Minimal invasive, or more specifically laparoscopic surgery is now the standard procedure in an increasing number of surgical specialties. Inflating the abdomen with CO2 for long periods confronts the anesthesiologist with a number of problems that influence the choice of anesthetic and the monitoring deemed necessary. The increased intraabdominal pressure (IAP) and for some operations the extreme Trendelenburg position can disturb alveolar ventilation and compromise oxygenation. ⋯ Balanced anesthesia or total intravenous anesthesia is to be preferred, and the drugs employed should have rapid elimination kinetics with a short recovery time, since wound closure time is drastically reduced. Inhalational anesthesia alone may inhibit hypoxic pulmonary vasoconstriction thereby unduly increasing oxygen desaturation. The necessary degree of muscle relaxation still remains to be defined.
