Randomized Controlled Trial Clinical Trial
Warmed humidified inspired oxygen accelerates postoperative rewarming.
To investigate the efficacy of warmed, humidified inspired oxygen (O(2)) for the treatment of mildly hypothermic postoperative patients. ⋯ Warming and humidifying inspired O(2) hastens recovery from hypothermia in postoperative patients.

Comparative Study Clinical Trial
Transesophageal echocardiographic assessment of pulmonary arterial and venous flow during high-frequency jet ventilation.
To evaluate high-frequency jet ventilation (HFJV) effects on pulmonary arterial and venous flow compared to those of intermittent positive-pressure ventilation (IPPV) by using pulsed Doppler transesophageal echocardiography. ⋯ Our results suggest that, in comparison to IPPV, HFJV significantly decreases pulmonary arterial pressure and left atrial pressure, resulting in significant increases in cardiac output and ejection fraction in healthy anesthetized adults.

To evaluate the effects of unilateral stellate ganglion blockade on left ventricular function. ⋯ In patients without cardiovascular disease, unilateral denervation of the left ventricle after stellate ganglion block produces no clinical deleterious effects on left ventricular function.

To measure sound levels that our patients are exposed to in the surgical suite and their perception of these sound levels. ⋯ Noise prevention in the OR and recovery room needs more attention and should be a routine part of patient care.

Clinical Trial
Poor prediction of blood transfusion requirements in adult liver transplantations from preoperative variables.
To assess the ability of preoperative information to predict intraoperative blood transfusion requirements in adult orthotopic liver transplantation. ⋯ Preoperative variables are poor predictors of intraoperative transfusion requirements even when significant associations exist, identifying a small proportion of the variability observed. A predictive approach based on this method would be too inaccurate to be of clinical use. The majority of the variability in transfusion requirements during liver transplantation most likely results from intraoperative and donor organ factors.
