简要总结
The proposed study will measure the time from the end of surgery until the time patients meet the discharge criteria from the postoperative anesthesia care unit and the time from the end of surgery until the patients regained cognitive function after anesthesia.
详细描述
Hypercapnia has been used in conjunction with hyperpnoea to provide a more rapid return of responsiveness after inhaled anesthesia. In our first clinical study with isoflurane we confirmed that the time from turning off the vaporizer to opening of eyes was shortened by an average of 62% when the minute ventilation was elevated and the end tidal carbon dioxide concentration was kept at 52 mmHg rather than 28 mmHg during emergence. In our second study we found that hypercapnia and hyperpnoea accelerated recovery proportionately for sevoflurane and desflurane. The benefits of accelerating subject recovery in the operating room may extend to the entire recovery period if the subject is more alert and easier to care for when they arrive in the post anesthesia care unit.

结局指标
主要结局
Recovery From Anesthesia
时间窗: up to 2 hours
average time in minutes from the time the surgeon finished closing the surgical incision until the time the investigator in the postoperative care unit determined that the patients meet the discharge criteria from the postoperative anesthesia care unit (their vital signs had been stable for at least 30 min, their pain scores were less than the tolerable pain scores, they could sit up without dizziness or nausea, and their Aldrete score was ≥8).
次要结局
- Return of Cognitive Function(up to 30 minutes)
