[Anesthesia for pulmonary trunk aneurysmorrhaphy].

Background And Objectives: The aneurysm in the pulmonary trunk is a rare disease. Because of its location, a rupture can lead to right ventricular failure and sudden death. Aneurysmorraphy is the most widely used surgical treatment in these cases.

Intravenous clonidine administration and its ability to reduce pulmonary arterial pressure in patients undergoing heart surgery.

Objective: Evaluate the ability of clonidine to reduce pulmonary arterial pressure in patients with pulmonary hypertension undergoing heart surgery, either by reducing the pressure values from the direct measurement of pulmonary arterial pressure or by reducing or eliminating the need for intraoperative dobutamine and nitroprusside.

Method: Randomized, double-blind, placebo-controlled, comparative study conducted in 30 patients with pulmonary arterial hypertension type 2 undergoing cardiac surgery. Mean pulmonary arterial pressure and dosage of dobutamine and sodium nitroprusside were assessed four times: before intravenous administration of clonidine (2 μg/kg) or placebo (T0), 30 min after tested treatment and before cardiopulmonary bypass (T1), immediately after CPB (T2), 10 min after protamine injection (T3).

Ondansetron for the prevention of postoperative nausea and vomiting: which is the best dosage for aesthetic plastic surgery?

Background: Ondansetron has been used widely in plastic surgery to prevent postoperative nausea and vomiting. A literature search showed controversial dosages of this drug, and because of its short half-life, its use only before anesthetic induction could have a limited effect. The purpose of this study was to assess the efficacy of intravenous (IV) ondansetron (4 mg) for aesthetic plastic surgery performed with the patient under general anesthesia and the prophylaxis of postoperative nausea and vomiting (PONV) in two situations: (a) only before anesthetic induction and (b) before anesthetic induction and immediately before extubation.
