To examine the anesthetic gas leakage and prelaryngeal position of the laryngeal mask airway (LMA). ⋯ The LMA is a new airway management technique with good qualities of tightness and ventilation conditions. However, contraindications such as patients with a full stomach, intra-abdominal surgery, high peak airway pressure, prolonged operation, and an inexperienced anesthesiologist apply.

Randomized Controlled Trial Clinical Trial
Fenoldopam infusion for the treatment of postoperative hypertension.
To examine the safety and efficacy of intravenous fenoldopam as compared to placebo for the treatment of postoperative hypertension. ⋯ Fenoldopam is an effective drug for reducing BP following hypertensive episodes in the postoperative setting. Fenoldopam use is associated with an increase in HR versus placebo.

Comparative Study
Thromboelastography and Sonoclot analysis in the healthy parturient.
To compare values for two whole blood viscoelastic coagulation tests, thromboelastography (TEG) and Sonoclot analysis (Sonoclot R Coagulation Analyzer, Sienco, Inc., Morrison, CO), between healthy parturients and nonparturients. ⋯ The differences found in the parturients reflect a hypercoagulable state. If these tests are to be used in evaluating obstetric patients, the results should be compared with values obtained for healthy parturients, not healthy nonparturients.
-
To investigate the effect of intravenous (IV) phenylephrine (PHE) bolus administration on left ventricular function in patients who developed postural hypotension during isoflurane anesthesia in the head-up tilt (reverse Trendelenburg) position. ⋯ PHE bolus administration effectively restored BP and cardiac filling, which were reduced after head-up tilt, without causing a relevant impairment of left ventricular function or an increase in end-systolic wall stress above the upper normal limit.
-
To determine (1) the general risk and outcome in the recovery room among 4 different anesthetic techniques associated with 2 different extracorporeal shock wave lithotripsy (ESWL) machines and (2) any gender-related differences among patients undergoing ESWL. ⋯ (1) Overall, ESWL is relatively safe. Both machine types and all anesthetic techniques exhibited a low risk and good outcome. (2) There appear to be gender-related differences during ESWL. Female and male patients may have different pain and nausea and/or vomiting thresholds during ESWL.
