To determine the frequency of true and false alarms and to determine the frequency of alarm failures for various parameters when using a postanesthesia monitoring system. ⋯ The high frequency of apnea strongly motivates the use of continuous RR monitoring, preferably by flow-sensing techniques, since both central and obstructive apneas are then detected. Further study and development is necessary before pulse oximetry can be unconditionally recommended for postanesthesia monitoring.

Randomized Controlled Trial Clinical Trial
Changes in end-tidal carbon dioxide during gynecologic laparoscopy: spontaneous versus controlled ventilation.
To study the changes in PETCO2 during spontaneous and controlled ventilation in patients undergoing gynecologic laparoscopy. ⋯ In view of the high PETCO2 levels, spontaneous breathing should be avoided during gynecologic laparoscopy, and ventilation to an initial PETCO2 of 4 kPa (30 mmHg) is recommended during controlled ventilation.

To evaluate the relative contribution of general anesthesia alone and in combination with the surgical procedure to the pathogenesis of late postoperative hypoxemia. ⋯ General anesthesia in itself is not an important factor in the development of late postoperative constant and episodic hypoxemia, which instead may be related to the magnitude of trauma and/or opioid administration.
