生长抑素对急腹症患儿术后胃肠功能及应激水平影响的前瞻性随机对照研究

Effect of somatostatin on postoperative gastrointestinal function and stress level in children with acute abdomen: a prospective randomized controlled study

摘要:

目的 探讨生长抑素对急腹症患儿术后胃肠功能及应激水平的影响。 方法 选取2019年8月至2021年6月徐州市儿童医院收治的行手术治疗的102例急腹症患儿为研究对象。将患儿随机分为观察组和对照组，每组各51例。对照组患儿术后给予止血、抗感染等常规治疗，观察组在常规治疗的基础上加用生长抑素。术前、术后第1天及术后第5天采集两组患儿外周血，比较两组患儿血清血管内皮素-1（endothelin-1，ET-1）、促肾上腺皮质激素（adrenocorticotropic hormone，ACTH）、皮质醇（cortisol，Cor）及胃泌素、胃动素水平，以及两组患儿术后恢复情况及并发症发生率。 结果 术前两组患儿血清ET-1、ACTH、Cor、胃动素及胃泌素水平差异无统计学意义（P>0.05）。术后第1天、第5天，观察组患儿血清ET-1、ACTH、Cor水平均显著低于对照组（P<0.05）；术后第5天，观察组患儿胃动素与胃泌素水平均高于对照组（P<0.05）。术后观察组患儿首次肛门排气时间、肠鸣音恢复时间、首次排便时间、住院时间均较对照组缩短（P<0.05）。观察组并发症发生率（6%）显著低于对照组（24%，P<0.05）。 结论 生长抑素可显著降低急腹症患儿术后应激反应，改善胃肠功能，降低并发症发生率，有益于疾病预后。

Abstract:

Objective To study the effect of somatostatin on postoperative gastrointestinal function and stress level in children with acute abdomen. Methods A total of 102 children with acute abdomen who underwent surgery in Xuzhou Children's Hospital from August 2019 to June 2021 were enrolled as subjects and were randomly divided into an observation group and a control group, with 51 children in each group. The children in the control group were given conventional treatment such as hemostasis and anti-infective therapy after surgery, and those in the observation group were given somatostatin in addition to conventional treatment. Peripheral blood samples were collected from both groups before surgery and on days 1 and 5 after surgery. The two groups were compared in terms of the serum levels of endothelin-1 (ET-1), adrenocorticotropic hormone (ACTH), cortisol, gastrin, and motilin, postoperative recovery, and the incidence rate of complications. Results There was no significant difference in the serum levels of ET-1, ACTH, cortisol, gastrin, and motilin between the two groups before surgery (P>0.05). Compared with the control group, the observation group had significantly lower serum levels of ET-1, ACTH, and cortisol on days 1 and 5 after surgery (P<0.05) and significantly higher levels of motilin and gastrin on day 5 after surgery (P<0.05). Compared with the control group, the observation group had significantly shorter time to first passage of flatus, first bowel sounds, and first defecation after surgery, as well as a significantly shorter length of hospital stay (P<0.05). The incidence rate of complications in the observation group was significantly lower than that in the control group (6% vs 24%, P<0.05). Conclusions In children with acute abdomen, somatostatin can significantly reduce postoperative stress response, improve gastrointestinal function, and reduce the incidence rate of complications, thereby helping to achieve a good prognosis.
