Randomized Controlled Trial Comparative Study Clinical Trial
Work of breathing in anesthetized patients: laryngeal mask airway versus tracheal tube.
To compare the work of breathing associated with the laryngeal mask airway (LMA) and tracheal tube (TT) in spontaneously breathing anesthetized patients. ⋯ In healthy, anesthetized, spontaneously breathing patients, work of breathing is significantly lower through the LMA than the TT.

Clinical Trial Controlled Clinical Trial
Fluid resuscitation, nutritional support, and cholesterol in critically ill postsurgical patients.
To determine how and why cholesterol concentrations decrease after surgery, and the effect of the administration of nutritional support. ⋯ Serum cholesterol concentrations, like those of serum albumin and total protein, are markedly reduced immediately following major abdominal surgery, often to levels reported in malnutrition. Dilution by IV fluid and redistribution into an expanded extracellular fluid space are likely the major causes of these decreases. Serum cholesterol concentrations are therefore not useful in the nutritional assessment of patients in the immediate postoperative period.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of recovery after sevoflurane or desflurane in ambulatory anesthesia.
To determine if there is a difference between sevoflurane and desflurane when used as part of a balanced anesthetic technique in terms of time to discharge from an ambulatory surgery unit. ⋯ Recovery indices and psychomotor function are marginally but not significantly better with sevoflurane than desflurane.

To characterize the clinical features that predispose to sinus bradycardia and cardiac arrest during spinal and epidural anesthesia. ⋯ The clinical picture suggests a reflex cause, possibly associated with low right-sided cardiac filling pressure. No common precipitating cause or high-risk patient profile was noted.
