Randomized Controlled Trial Comparative Study Clinical TrialRocuronium versus vecuronium during fentanyl induction in patients undergoing coronary artery surgery.
To evaluate the neuromuscular, ventilatory, and cardiovascular effects of rocuronium and vecuronium. ⋯ During narcotic induction of anesthesia, rocuronium was associated with lower requirement for vasopressors, faster onset of neuromuscular blockade, and better conditions for mask ventilation and tracheal intubation compared with vecuronium.

Recurrent laryngeal nerve palsy after cardiovascular surgery: relationship to the placement of a transesophageal echocardiographic probe.
To examine the relationship between the incidence of recurrent laryngeal nerve palsy after cardiovascular surgery and the placement of a transesophageal echocardiographic probe. ⋯ These results suggest that placement of the transesophageal echocardiographic probe is not responsible for postoperative recurrent laryngeal nerve palsy. It seems likely that surgical manipulation itself and the durations of surgery, cardiopulmonary bypass, and tracheal intubation are related to the incidence of laryngeal nerve palsy.

Cerebral oxygenation during cardiopulmonary bypass measured by near-infrared spectroscopy: effects of hemodilution, temperature, and flow.
To determine the effects of hemodilution, PaCO2, PaO2, arterial pressure, and temperature on cerebral oxygenation during mild hypothermic cardiopulmonary bypass (CPB). ⋯ In early stages of CPB, a diminished cerebral oxygen supply was found, which may be caused by acute hemodilution. Despite an increased extraction of oxygen as demonstrated by the decrease in Hb-diff, cerebral energy balance reflected by CtO2 was maintained within a safe range during cooling. Because NIRS measures regional cerebral oxygenation, it is useful as an adjunct to global measures in the early noninvasive detection of cerebral hypoxia.

The association between preoperative patient characteristics and both clinical and economic outcomes after abdominal aortic surgery.
To evaluate the association between patient characteristics and both clinical and economic outcomes in patients having abdominal aortic surgery in Maryland between 1994 and 1996. ⋯ In patients having aortic surgery, several patient characteristics such as mild liver disease and chronic renal failure, were associated with increased in-hospital mortality and length of stay. The practice of admitting patients to the hospital 1 to 2 days before surgery should be reevaluated because this was not associated with reduced in-hospital mortality but was associated with increased hospital and ICU stay.
