目的 探讨个体化肠内营养支持在胃肠术后早期应用的可行性及安全性。方法 选取2022年1月—12月安徽省亳州市中医院普通外科收治的胃肠手术患者100例。使用随机数字表法将患者随机为观察组和对照组,每组各50例。观察组在常规治疗基础上实施个体化肠内营养,持续7 d。对照组则接受术后常规处理。术后第7天测定实验室指标,并比较两组胃肠功能的恢复情况。结果 观察组术后肛门首次排气时间短于对照组[（55.41±19.63）h vs （81.46±19.39） h],前白蛋白水平高于对照组[（241.14±65.73）g/L vs（217.35±51.63）g/L],组间比较差异有统计学意义（P<0.05）。血清总蛋白水平[（70.55±18.89）g/L vs （68.16±20.05）g/L]、血清白蛋白水平[（53.22±17.76）g/L vs（50.76±18.54）g/L]、淋巴细胞计数[（1.60±0.54）×10⁹/L vs （1.56±0.55）×10⁹/L]以及肛门排便时间[（89.67±22.31）h vs （97.77±21.27）h ]在组间比较差异无统计学意义（P>0.05）。结论 根据个体情况在胃肠术后早期实施个体化的肠内营养支持是安全可行的,能够促进胃肠功能的快速恢复,从而改善患者的营养状况。

Objective To investigate the feasibility and safety of personalized enteral nutrition support during the early postoperative period of gastrointestinal surgery．Methods A total of 100 patients who underwent gastrointestinal surgery at the Department of General Surgery,Bozhou Hospital of Traditional Chinese Medicine,who were enrolled in this study during January 2022 to December 2022．Patients were randomly allocated into either the observational or control group,with 50 patients in each group．The randomization was performed using a random number table．The observational group received personalized enteral nutrition support in addition to routine treatment for 7 days．The control group received standard postoperative care．Laboratory indicators were measured on the 7th postoperative day to compare recovery of gastrointestinal function between the two groups．Results The observational group exhibited a significantly shorter time to the first passage of flatus from the anus compared to the control group（55.41±19.63 h vs 81.46±19.39 h,P<0.05）,as well as higher prealbumin levels（241.14±65.73 g/L vs 217.35±51.63 g/L,P<0.05）．However,there were no significant differences between the two groups in terms of serum total protein levels（70.55±18.89 g/L vs 68.16±20.05 g/L）,serum albumin levels（53.22±17.76 g/L vs 50.76±18.54 g/L）,lymphocyte counts[（1.60±0.54）×10⁹/L vs （1.56±0.55）×10⁹/L],and time to the first defecation from the anus（89.67±22.31 h vs 97.77±21.27 h）（all P>0.05）．Conclusions Personalized enteral nutrition support based on individual conditions is safe and feasible in the early postoperative period of gastrointestinal surgery．It can promote the rapid recovery of gastrointestinal function and improve patients' nutritional status．

目的 观察肺保护性通气策略对肺功能不全胃肠手术患者术后转归影响。方法 选取2016年4月—2017年3月期间我院收治的90例肺功能不全胃肠手术患者作为研究对象,根据随机数字表将患者随机分为观察组和对照组,每组各45例。对照组采用传统机械通气方式,观察组采用肺保护性通气方式。观察两组患者动脉血气指标、自主呼吸恢复时间、清醒时间、拔管时间、PACU观察时间及住院期间术后肺部并发症发生情况。结果 两组患者麻醉时间、手术时间、晶胶液输入情况、麻醉药物用量差异无统计学意义（P>0.05）。观察组患者术后PaO₂高于对照组,差异有统计学意义（P<0.05）。两组患者自主呼吸恢复时间、清醒时间、拔管时间、PACU观察时间比较,差异均无统计学意义（P>0.05）。观察组患者住院期间PPCs发生率低于对照组,差异有统计学意义（P<0.05）。结论 肺保护性通气策略可有效改善肺功能不全胃肠手术患者术后氧合,降低患者住院期间PPCs发生率,对于患者术后转归具有积极的作用。

Objective To observe the effect of lung protective ventilation strategy on postoperative outcome of patients with pulmonary insufficiency of gastrointestinal surgery. Methods 90 patients with pulmonary insufficiency gastrointestinal surgery in our hospital from April 2016 to March 2017 were selected as study subjects. According to the random number table,patients were randomly divided into observation group and control group,with 45 cases in each group. The control group used traditional mechanical ventilation,and the observation group used lung protective ventilation. Arterial blood gas parameters,spontaneous breathing recovery time,awakening time,extubation time,PACU observation time and postoperative pulmonary complications in both groups were observed. Results There was no significant difference in anesthesia time,operation time,crystal glue fluid input,and anesthetic drug dosage between the two groups （P>0.05）. The postoperative PaO₂ was higher in the observation group than in the control group （P<0.05）. There was no significant difference between the two groups in spontaneous breathing recovery time,awakening time,extubation time,and PACU observation time （P>0.05）. The incidence of PPCs was lower in the observation group than that in the control group,and the difference was statistical difference （P<0.05）. Conclusion Lung protective ventilation strategy may effectively improve postoperative oxygenation in patients with pulmonary insufficiency and gastrointestinal surgery,reduce the incidence of PPCs during hospitalization,and have a positive effect on postoperative outcome.
