Case Reports[Thrombocytopenia and thrombophilic state in heparin therapy].
The authors report two clinical cases of thrombocytopenia and thrombosis which occurred during profilaxys and therapy with heparin. The mechanisms involved are reviewed and the possible therapeutic role of heparin-like drugs is discussed according to data presented in the international literature.

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.

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.

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.

Comparative Study[Comparison of bench central and mixed pulmonary venous oxygen saturation in critically ill postsurgical patients].
To investigate if there were differences between bench central oxygen saturation (ScvO2) and mixed venous oxygen saturation (SvO2) in a group of acutely ill postsurgical patients. ⋯ SvO2 cannot be predicted well from bench ScvO2, nor changes in ScO2 can be predicted wel from changes in bench ScvO2. Therefore, in this category of patients, the clinical usefulness of monitoring bench ScvO2 is strongly limited and we must still rely on the SvO2.
