Comparative Study Controlled Clinical Trial
Age-dependent relationship between bispectral index and sedation level.
To determine the relationship between bispectral index (BIS) and sedation. ⋯ BIS correlated with sedation depth, with BIS scores in group H than group M at a deep sedation depth.

Randomized Controlled Trial Comparative Study
A clinical evaluation of four disposable laryngeal masks in adult patients.
To compare the clinical use of four disposable laryngeal masks (DLMs): the Ambu laryngeal mask [Ambu LM], Solus, Laryngeal Mask Airway (LMA) Unique, and Soft Seal. ⋯ The Ambu LM and LMA Unique DLMs appear to be easier to insert by inexperienced residents and are less traumatic for the patient. The Soft Seal achieves a higher airway seal than other devices, but it causes more mucosal trauma. The Solus had the highest insertion failure rate of the 4 groups.

Randomized Controlled Trial Comparative Study
Gastroesophageal regurgitation during anesthesia and controlled ventilation with six airway devices.
To investigate the frequency of gastroesophageal regurgitation and respiratory mechanics during positive pressure ventilation using 5 supraglottic devices or an endotracheal tube (ETT). ⋯ The frequency of gastroesophageal regurgitation in anesthetized, unparalyzed, mechanically ventilated patients was similar in patients whose lungs were ventilated with either the Cobra Perilaryngeal Airway, LMA Classic, Fastrach, ProSeal, laryngeal tube, or ETT.

Randomized Controlled Trial
Development and performance of a two-step desflurane-O(2)/N(2)O fresh gas flow sequence.
To determine if the previously described single-step O(2)/N(2)O fresh gas flow (FGF) sequence could be combined with a simple desflurane vaporizer (F(D)) sequence to maintain the end-expired desflurane (F(A)des) at 4.5% with the anesthesia delivery unit machine (ADU Anesthesia Machine(R); General Electric, Helsinki, Finland). ⋯ One O(2)/N(2)O rotameter FGF setting change from 6 to 0.7 L per minute after three minutes and one desflurane F(D) change from 6.5% to 5.5% after 15 minutes maintained anesthetic gas concentrations within predictable and clinically acceptable limits during the first 20 minutes.

Randomized Controlled Trial Comparative Study
Hemodynamic effects of 6% and 10% hydroxyethyl starch solutions versus 4% albumin solution in septic patients.
To compare the hemodynamic effects of two different concentrations of pentastarch hydroxyethyl starch (HES; 200/0.5) solutions with a 4% human albumin solution for fluid resuscitation. ⋯ HES is as effective as albumin for volume resuscitation in septic patients.
