Randomized Controlled Trial Clinical Trial[Effects of betamethasone on neuromuscular blockade induced by vecuronium in continuous infusion].
The aim of the study was to determine a possible interaction between a corticosteroid (betamethasone) and vecuronium, a nondepolarizing muscle relaxant. The authors studied 20 patients, ASA I-II, aged 20-54, both sexes, scheduled for abdominal surgery. ⋯ The recovery rate of vecuronium after stopping infusion at 10% recovery was also evaluated. Corticosteroids may interact with non-depolarizing muscle relaxants both in prejunctional and postjunctional acetylcholine receptors by several mechanisms of action.

Randomized Controlled Trial Clinical Trial[Early postoperative hypoxemia: incidence and effectiveness of oxygen administration].
To determine the incidence of hypoxaemia and the efficacy of oxygen therapy in the early postoperative period. ⋯ There is a high incidence of clinically unsuspected hypoxaemia in the early postoperative period, the use of supplemental oxygen reduces but does not prevent hypoxaemic episodes, every patient should be monitored continuously with a pulse oximeter in the recovery room.

Randomized Controlled Trial Clinical Trial[Continuous venous infusion of buprenorphine with autonomous elastomeric system in the control of postoperative pain].
We herein evaluated the analgesic effectiveness of low doses of buprenorphine with or without a primer and the practicality and usefulness of a constant flow disposable infusion set (Infusor Baxter 2 ml/h). Our series consists of 300 patients, seen between January 1992 and December 1993, randomly distributed in three groups of 100 patients each. All patients were informed before operation about the use of pain Visual Analogical Scale (VAS) and how the infusor works. ⋯ Group B and C patients showed blood pressure, heart rate and respiratory rate values significantly reduced compared to group A patients at T0 and T1. Such values however then stabilized. Side effects encountered were nausea and vomiting in different percentages in the three groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical Trial[Double-blind placebo-controlled study of the effectiveness and tolerability of 10 and 30 mg ketorolac tromethamine suppositories in post-cholecystectomy pain].
To evaluate the efficacy and tolerability of ketorolac tromethamine 10 mg and 30 mg suppositories in comparison to placebo, after single dose administration in patients suffering from post-operative pain after cholecystectomy. ⋯ This study shows that ketorolac 30 mg suppositories are effective in clinical conditions, such as after surgery, in which pain control must be achieved within the shortest time interval and maintained or improved by means of a single route of administration.

Randomized Controlled Trial Comparative Study Clinical Trial[Effects of age, body weight, and ventilatory pattern on the difference between arterial and end-tidal PCO2].
To evaluate the effects of physiological ventilatory patterns on P(a-ET)CO2 gradient and on the alveolar dead space production during controlled mechanical ventilation. ⋯ Ventilatory setting, used in a normal physiological range, don't affect P(a-ET)CO2 difference during mechanical ventilation. Age, body weight and airway pressure of the patient must be considered to obtain a correct value of PaCO2 by the measure of PETCO2.
