Postoperative recovery of arterial oxygen saturation determined by pulse oximetry in pediatric patients.
Small children are physiologically subject to arterial oxygen desaturation. However, few reports have referred to the risk factors related to postanesthetic hypoxemia and the duration of hypoxemia. The purpose of this study was to clarify these two aspects. ⋯ Age, height, and weight of these 10 children were significantly different from the remaining 75, but there were no significant differences in anesthetic duration and postanesthetic awakefulness between the group with postanesthetic hypoxemia and the one without. The importance of monitoring the clinical condition of pediatric patients after general anesthesia is universally acknowledged. Monitoring with the pulse oximeter has proven very useful and shows that, unless oxygen saturation is monitored, all children should receive supplemental oxygen.

Randomized Controlled Trial Multicenter Study Clinical Trial
A double-blind, placebo-controlled pilot study examining the effectiveness of intravenous ondansetron in the prevention of postoperative nausea and emesis.
To compare the efficacy and safety profiles of ondansetron and a placebo when infused immediately prior to anesthesia induction for the prevention of postoperative nausea and emesis (vomiting or retching). ⋯ Ondansetron, infused IV before anesthesia induction, appears to be safe and effective when used in the prevention of postoperative nausea and emesis.

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)

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.
