构建复方聚乙二醇电解质散联合西甲硅油用于结肠镜检查肠道准备的系统化护理方案，并探究其应用效果。

选取2023年3月至2025年5月经解放军总医院第一医学中心消化内科医学部结肠镜检查的92例住院患者，采用随机数表法分为对照组和研究组，每组各46例。鉴于临床仍普遍存在单用复方聚乙二醇电解质散、未常规联用祛泡剂且护理不规范的现状，对照组采用传统方案(复方聚乙二醇电解质散＋常规护理，不加西甲硅油)；研究组遵循指南推荐，联用西甲硅油并实施系统化护理。比较两组患者的肠道清洁度、肠内祛泡效果、不良反应发生率以及护理服务满意度。

研究组肠道清洁度有效率为91.30%，肠内祛泡效果优良率为91.30%，均显著高于对照组的65.22%和60.87%；研究组不良反应发生率为4.35%，显著低于对照组的30.43%；研究组护理服务满意度为97.83%，高于对照组的86.96%，组间各项指标差异均具有统计学意义(P<0.05)。

新构建的系统化护理方案联合复方聚乙二醇电解质散与西甲硅油，可显著改善肠道清洁度与祛泡效果，降低腹痛、腹胀、恶心等不良反应，提升护理服务满意度，药物联合与精细化护理协同作用显著，临床推广价值较高。

To construct a systematic nursing protocol for bowel preparation with polyethylene glycol electrolyte powder combined with simethicone in colonoscopy, and to explore its application efficacy.

A total of 92 inpatients who underwent colonoscopy in our hospital from March 2023 to May 2025 were selected and divided into the control group and the study group by the random number table method, with 46 cases in each group.Considering that polyethylene glycol electrolyte powder is commonly used alone without routine defoaming agents and standardized nursing in clinical practice, the control group received the traditional regimen (polyethylene glycol electrolyte powder combined with routine nursing without simethicone); the study group adopted simethicone in accordance with guideline recommendations combined with systematic nursing.The bowel cleansing quality, intra- intestinal defoaming effect, incidence of adverse reactions and nursing satisfaction were compared between the two groups.

In the study group, the effective rate of bowel cleansing and the excellent and good rate of defoaming effect were both 91.30%, which were significantly higher than 65.22% and 60.87% in the control group.The incidence of adverse reactions in the study group was 4.35%, significantly lower than 30.43% in the control group; the nursing satisfaction rate was 97.83%, higher than 86.96% in the control group, with statistically significant differences between groups (P<0.05).

The newly constructed systematic nursing protocol combined with polyethylene glycol electrolyte powder and simethicone can significantly improve bowel cleansing quality and defoaming effect, reduce adverse reactions such as abdominal pain, abdominal distension and nausea, and increase nursing satisfaction.The combination of medication and refined nursing presents a remarkable synergistic effect, which is worthy of clinical promotion.
