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.

Clinical Trial[Effects of inhalation anesthetics on intracranial pressure and cerebral blood flow velocity].
Inhalation anesthetics diminish cerebrovascular resistance, augmenting cerebral blood flow (CBF) and hematic volume. This may lead to a dangerous increase in intracranial pressure (ICP). It has been observed that isoflurane used in hypocapnia does not appear to cause an increase in ICP equal to that caused by other inhalation anesthetics. ⋯ The results show that during hypocapnia isoflurane causes significant reductions in MAP and CCP whereas ICP and CFV tend to diminish but not significantly. On the contrary, isoflurane in normocapnia causes an increase in ICP and a further and more marked reduction in CPP with a corresponding but not significant increase in CFV. In conclusion, in the light of these results the increase in ICP and the contemporary reduction of MAP would appear to restrict the use of isoflurane in normocapnia in patients with intracranial pathologies.(ABSTRACT TRUNCATED AT 250 WORDS)

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.
