不同饮水时间对全麻腰椎手术禁食患者口腔舒适度的影响

Effects of different times for drinking on oral comfort of fasting patients undergoing lumbar surgery at general anesthesia

目的探讨全麻腰椎手术后禁食患者不同饮水时间对口腔舒适度的影响。方法将行全麻腰椎手术后禁食的患者100例,在麻醉清醒后按患者术后是否有饮水欲望分为实验组(有饮水欲望)与对照组(无饮水欲望),每组各50例,实验组患者在术后麻醉清醒后肛门未排气时给予饮水5mL,30min后给予饮水10mL;对照组患者按骨科术后常规护理肛门排气后饮水。观察两组患者术后8h与24h口腔舒适度及pH值情况。结果两组患者术后24h口腔舒适度评分及口干发生率、唾液pH值比较,均P<0.01,差异具有统计学意义。结论全麻腰椎手术后禁食患者在麻醉清醒后肛门未排气前饮水可有效改善口腔内环境,提高患者口腔舒适度。

Objective To investigate the effects of different times for drinking on oral comfort of patients undergoing lumbar surgery at the general anesthesia. Methods 100 fasting patients having undergone lumbar surgery at general anesthesia were divided into experiment group and control group in equal number according to if they desired to drink water when they were awakened from anesthesia. In the former group, the patients were administered with 5 mL water when they were awake and had no anal air bleed and 30 minutes later those having no abdominal distension with 10 mL water. In the control group, the patients were allowed for drinking. The degree of oral comfort at 8 and 24 hours as well as pH after surgery were observed and compared between the two groups. Results The differences in 24 h oral comfort and pH after surgery were statistically significant between the two groups （P 〈 0.01）. Conclusion For the patients having undergone lumbar surgery at general anesthesia, drinking some water when they are awakened but have no anal air bleed may help to improve the oral environment and thus their oral comfort.
