Postoperative thirst is one of the most intense, common and easily ignored subjective discomforts in patients after gynecological surgery. This study aimed to investigate whether early oral hydration on demand in the postanesthesia care unit (PACU) after gynecological laparoscopy under general anesthesia can appease postoperative thirst and increase patient comfort.
Participants were randomized into the intervention and control groups. Patients in the intervention group were allowed to achieve early oral hydration on demand in the PACU if they were evaluated as fully conscious, with stable vital signs, grade 5 muscle strength, and well-recovered cough and swallowing reflex. However, the total amount of water intake throughout the entire study should not exceed 0.5mL/kg. During the study, the frequency of water intake, the total amount of water intake and adverse events were accurately recorded. The control group was managed according to the routine procedures and began to drink water 2 h after anesthesia. The intensity of thirst and subjective comfort in patients were assessed using the visual analog scale (VAS) when they entered and left the PACU.
No statistically significant differences were identified in age, height, weight, body mass index, pre-operative fasting time, duration of surgery, intraoperative fluid intake, intraoperative blood loss, intraoperative urine volume, and thirst intensity and subjective comfort scores between the groups before intervention (P > 0.05). After intervention, the VAS score for thirst intensity in the intervention group significantly decreased (P < 0.05), and the VAS score for subjective comfort in the intervention group significantly increased (P < 0.05). No adverse events were detected in both groups during the entire study.
Early oral hydration on demand in the PACU can safely and effectively relieve postoperative thirst in patients, and improve patient comfort after gynecological laparoscopy.

术后口渴是妇科手术后患者最强烈、最常见且容易被忽视的主观不适之一。本研究旨在探讨全麻妇科腹腔镜手术后在麻醉后恢复室（PACU）按需早期口服补液是否能缓解术后口渴并增加患者舒适度。
参与者被随机分为干预组和对照组。如果患者被评估为完全清醒，生命体征稳定，肌力 5 级，咳嗽和吞咽反射恢复良好，则允许在 PACU 按需早期口服补液。但是，整个研究过程中的总饮水量不应超过 0.5mL/kg。在研究过程中，准确记录了饮水频率、总饮水量和不良事件。对照组按照常规程序进行管理，麻醉后 2 小时开始饮水。患者进入和离开 PACU 时，使用视觉模拟评分（VAS）评估口渴强度和主观舒适度。
干预前两组患者的年龄、身高、体重、体重指数、术前禁食时间、手术时间、术中液体摄入量、术中失血量、术中尿量、口渴强度和主观舒适度评分均无统计学差异（P>0.05）。干预后，干预组口渴强度的 VAS 评分显著降低（P<0.05），干预组主观舒适度的 VAS 评分显著升高（P<0.05）。在整个研究过程中，两组均未发生不良事件。
PACU 按需早期口服补液可安全有效地缓解妇科腹腔镜手术后患者的术后口渴，并提高患者舒适度。
