Vasopressin in vasoplegic shock in surgical patients: systematic review and meta-analysis.

Purpose: Vasoplegia, or vasoplegic shock, is a syndrome whose main characteristic is reducing blood pressure in the presence of a standard or high cardiac output. For the treatment, vasopressors are recommended, and the most used is norepinephrine. However, new drugs have been evaluated, and conflicting results exist in the literature.

Vasopressin Versus Norepinephrine for the Management of Septic Shock in Cancer Patients: The VANCS II Randomized Clinical Trial.

Objectives: Previous trials suggest that vasopressin may improve outcomes in patients with vasodilatory shock. The aim of this study was to evaluate whether vasopressin could be superior to norepinephrine to improve outcomes in cancer patients with septic shock.

Design: Single-center, randomized, double-blind clinical trial, and meta-analysis of randomized trials.

Hypoxemia after myocardial revascularization: analysis of risk factors.

Background And Objectives: Severe hypoxemia is complication frequently seen in the immediate postoperative period of myocardial revascularization (MR), increasing the duration of mechanical ventilation, the incidence of pulmonary infections, hospital costs, and mortality. The objective of this study was to identify predictive factors of severe hypoxemia in patients undergoing MR.

Methods: Four-hundred and eighty-one adult patients undergoing elective MR between October 2003 and March 2004 were enrolled in this study.
