This study was designed to evaluate the usefulness of three commonly used tests of psychomotor function and one test of short-term memory in assessing recovery from a brief nitrous oxide, oxygen and halothane anaesthetic. Twenty-six female patients undergoing minor gynaecological surgery were allocated to one of three treatment groups depending on premedication (placebo, low dose and high dose). Immediate recovery was most rapid in the placebo group. Both the tests of simple reaction time and picture recall were able to differentiate between the post-anaesthetic recovery of the high-dose group and that of the other two groups. Neither component of the letter cancellation test showed a clear difference in recovery pattern. Tests of critical flicker fusion were too unreliable to be of use in clinical decision making. Our results suggest that tests of reaction time and memory were more sensitive than letter cancellation in assessing recovery.
本研究旨在评估三项常用的精神运动功能测试和一项短期记忆测试在评估短暂一氧化二氮、氧气和氟烷麻醉后的恢复情况时的有用性。26名接受小型妇科手术的女性患者根据术前用药情况（安慰剂、低剂量和高剂量）被分配到三个治疗组之一。安慰剂组的即时恢复最快。简单反应时间测试和图片回忆测试都能够区分高剂量组与其他两组的麻醉后恢复情况。字母划消测试的两个部分在恢复模式上均未显示出明显差异。临界闪烁融合测试过于不可靠，无法用于临床决策。我们的结果表明，在评估恢复情况时，反应时间测试和记忆测试比字母划消测试更敏感。
