摘要 目的探讨分析小儿重症肺炎合并胃粘膜损伤诊断中胃粘膜pH值的应用价值。方法选取小儿重症肺炎合并胃粘膜损伤患儿36例作观察组,选同时期重症肺炎无胃粘膜损伤并发患儿38例作对照组,所有患儿均接受机械通气,在通气前后对患儿胃粘膜pH值进行测定并进行血气分析。结果观察组PgCO2-PaCO2显著高于对照组,而胃粘膜pH值、PaO2/FiO2与PaO2均显著低于对照组(P<0.05),经通气治疗后各指标均显著改善。胃粘膜pH值对小儿重症肺炎合并胃粘膜损伤诊断中敏感度为86.11%,特异度为76.32%。结论在重症肺炎合并胃粘膜损伤患儿中,胃粘膜pH值较低,可对胃粘膜中缺血缺氧状况予以敏感、准确反映,在该疾病诊断中具有较高临床价值。
