Comparative StudyFlow resistances of disposable double-lumen, single-lumen, and Univent tubes.
To compare the airflow resistances of modern double-lumen, single-lumen, and Univent (Fuji Systems Corp; Tokyo, Japan) tubes. ⋯ Flow resistances of modern disposable double-lumen tubes are lower than commonly perceived. In most clinical situations, there will be no decrease in flow resistance when a Rusch or Sheridan double-lumen tube is replaced by a single-lumen tube.

Randomized Controlled Trial Comparative Study Clinical TrialPleural bupivacaine placement for optimal postthoracotomy pulmonary function: a prospective, randomized study.
To determine dependent chest tube losses of bupivacaine with paravertebral versus interpleural administration, thereby helping to explain the significant differences in pulmonary function that exist between these two techniques. ⋯ Local anesthetic on the diaphragm might actively impair respiratory function through diaphragmatic and abdominal muscle weakness, while failing to contribute to pain relief.

Randomized Controlled Trial Comparative Study Clinical TrialPropofol-based versus fentanyl-isoflurane-based anesthesia for cardiac surgery.
To evaluate drug costs, time of mechanical ventilation, complications, and hospital length of stay comparing propofol-based with fentanyl-isoflurane-based anesthesia. ⋯ Fentanyl-isoflurane provides an inexpensive anesthetic that permits as prompt an extubation as propofol, thus conserving resources for other patients.

Randomized Controlled Trial Clinical TrialThe effect of etomidate induction on plasma cortisol levels in children undergoing cardiac surgery.
To investigate the effect of a single induction dose of etomidate on plasma cortisol and adrenocorticotrophic hormone (ACTH) levels in pediatric patients with congenital heart disease. ⋯ These results show that etomidate is a suitable agent for suppressing the increase in cortisol levels associated with the stress response caused by cardiopulmonary bypass in children with congenital heart defects, and can be used safely.
