Case Reports[Intracranial diffusion. A complication of retrobulbar anesthesia].
Retrobulbar anesthesia is considered a safe, effective local-regional technique for ocular surgery. However, local complications that can arise from needle trauma during injection, include retrobulbar hemorrhage, perforation of the ocular globe and occlusion of the artery and/or the central vein of the retina. Systemic complications, such as respiratory arrest, convulsions and cardiovascular collapse, have also been reported, and although they only occur in less than 1% of cases, they are potentially life threatening. We report two cases of intracranial diffusion after retrobulbar anesthesia and describe possible mechanisms that may contribute to its development.

Randomized Controlled Trial Clinical Trial[Prophylaxis of intraoperative nausea and vomiting with sub-hypnotic dose of propofol during intradural anesthesia in cesarean section].
To determine the preventive and therapeutic effect of 10 mg of propofol administered after delivery on the incidence of intraoperative nausea and vomiting (IONV) during intradural anesthesia for cesarean delivery. ⋯ Although 10 mg propofol has been described as an effective direct antiemetic, episodes of IONV were neither prevented nor reversed by its use during intradural anesthesia for cesarean delivery.

To compare the postoperative mortality of our hospital to that of others. ⋯ Risk factors for postoperative mortality established in other studies (advanced age, male sex, emergency surgery and ASA IV-V) were relevant in most of the deaths studied. Our mortality rate is similar to that reported by other authors for the first 24 to 48 hours after surgery, but is higher 30 days after surgery and later. Some of the 13 patients who died on the hospital ward in the first 48 hours after surgery probably did not receive the care that would have been provided in the postoperative intensive care unit.
