Randomized clinical study comparing active heating methods for prevention of intraoperative hypothermia in gastroenterology.

Objective: to compare the efficacy of three active heating methods in the prevention of intraoperative hypothermia in open gastroenterological surgeries.

Method: randomized clinical trial with a sample of 75 patients, whose initial body temperature measured by a tympanic thermometer. Esophageal temperature <36ºC was considered hypothermic.

Plasmatic vasopressin in patients undergoing conventional infra-renal abdominal aorta aneurysm repair.

Objectives: To evaluate plasmatic arginine vasopressin (AVP) levels in patients undergoing scheduled conventional abdominal aortic aneurysm (AAA) repair.

Methods: Plasmatic AVP concentrations were measured by radioimmunoassay in 22 non-consecutive adult patients undergoing infra-renal AAA repair. They were under combined general and epidural anesthesia at the following time frames: 1--pre-operative (T0); 2--2h (T1) and 6h (T2) after the surgical procedure; 3--in the morning at the first (T3), second (T4) and third (T5) post-operative days.

Vasopressin serum levels and disorders of sodium and water balance in patients with severe brain injury.

Background: Disorders of water and sodium balance are frequently seen in patients with severe brain injury (SBI), and may worsen their prognosis.

Purpose: To evaluate vasopressin (AVP) serum levels and sodium and water balance disorders during the first week post-injury in patients with SBI.

Method: Thirty-six adult patients with SBI (admission Glasgow Coma Scale score < or= 8) and an estimated time of injury View Article and Find Full Text PDF

Vasopressin serum levels in patients with severe brain lesions and in brain-dead patients.

Introduction: Patients with severe brain lesions (SBL) and brain-dead patients (BD) frequently present with vasopressin (AVP) secretion disorders.

Objective: To evaluate AVP serum levels in SBL and BD patients.

Design: Prospective, open label, observational trial.
