Randomized Controlled Trial Clinical Trial[Prevention of postoperative nausea and vomiting with ondansetron: a prospective, randomized, double-blind study in 90 patients].
Postoperative nausea and vomiting (PONV) are among the most common complications in surgical patients. In this prospective, double blind, parallel group study we compare the prophylactic antiemetic efficacy of ondansetron versus placebo in 90 patients undergoing general balanced anaesthesia. The patients were stratified according to the kind of surgery and randomly allocated to three treatment groups: 30 patients (Group A) received ondansetron 4 mg i.v. 1 hour before the induction of anaesthesia and placebo 1 hour before the end of surgery; 30 patients (Group B) received placebo 1 hour before the end of anaesthesia and ondansetron 4 mg i.v. 1 hour before the end of surgery; 30 patients (Group C-control group) received placebo in both the administrations. ⋯ Although the patients in Group A showed a lower incidence of PONV in comparison to the patients in Group B, such differences proved to be not statistically significant. No adverse effects in relation to drug administration were observed. We conclude that ondansetron 4 mg i.v. is safe and effective in preventing PONV in the surgical patients, particularly when administered before the induction of anaesthesia.

Clinical TrialVenous-arterial PCO2 and pH gradients in acutely ill postsurgical patients.
To investigate the venous-arterial PCO2 gradient, and the mixed venous blood acid-base status together with the oxygen transport variables in a group of acutely ill postsurgical patients. ⋯ This study suggests that in acutely ill postoperative patients increased venous-arterial PCO2 and pH gradients are directly and principally related to the reduction in blood flow and are both suggestive of low-flow state.

Case Reports[Tetraplegia and acute respiratory insufficiency from an ischemic cervical medulla lesion after cocaine use. A clinical case].
The article deals with a case report on tetraplegia and acute respiratory failure following ischemic damage of the spinal medulla in the cervical tract due to cocaine assumption. The ischemic damaged produced by cocaine usually injure the great vessels of the cranial base. The case report is particular because of the area and the seize of the injured vessel. Finally, the most important hypotheses about the pathogenesis in the ischemic cerebrovascular cocaine-induced damages are debated.
