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.
-
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.

Randomized Controlled Trial Comparative Study Clinical Trial
Propofol versus midazolam for monitored sedation: a comparison of intraoperative and recovery parameters.
To compare intraoperative and recovery parameters in patients who received either propofol infusion (PI), propofol bolus (PB), or midazolam bolus (MZ) for sedation. ⋯ The PI, PB, and MZ groups all gave excellent sedation for patients undergoing surgical procedures with local anesthesia. Amnesia was greatest with midazolam, and recovery was more rapid with propofol.
