[Intravenous anesthesia with propofol in intracranial surgery].
To analyze the repercussions of intravenous anesthesia with propofol as the single hypnotic drug on intracranial pressure (ICP) and cerebral perfusion pressure (CPP), and also to study the time until recovery from anesthesia and to tracheal extubation as well as intraoperative hemodynamic changes in patients undergoing surgery to remove a supratentorial brain tumor. ⋯ Intravenous anesthesia with propofol in intracranial surgery (supratentorial tumors) affords hemodynamic stability and lowers ICP except during laryngoscopy. Early recovery from anesthesia allows for neurological assessment and vigilance during the immediate postoperative period.

Transesophageal echocardiography is being used increasingly by anesthesiologists for monitoring and diagnosis. Real-time imaging provides valuable information about anatomy, preloading and cardiac contractility. Its use is mandatory in valve repair surgery and it has been shown to detect cardiac ischemia before any other monitoring tool. Programs to teach transesophageal echocardiography to anesthesiologists should be implemented; the availability of backup support staff from the echocardiography unit is of great value.

[Ondansetron in the prophylaxis of postoperative nausea and vomiting in ambulatory cataract surgery].
Postoperative nausea and vomiting (PONV) are potentially serious complications of ophthalmic surgery. We assess the efficacy of ondansetron for antiemetic prophylaxis in outpatient unilateral cataract surgery under retrobulbar blockade. ⋯ We found a high incidence of PONV, although the administration of ondansetron reduced PONV significantly.
