对24例急性感染患者进行冒粘膜pH值（pHi）测定并同时进行APACHEⅢ评分，对其中12例患者进行了经皮氧分压监测。结果：监测1小时后，2个脏器功能不全组pHi明显低于无MODS组，而APACHEⅢ评分无显著性差异；2个脏器功能不全组与3～4个脏器功能不全组的pHi与APACHEⅢ评分均存在显著性差异，说明在MODS早期pHi能及早反映器官系统受损情况，并通过pHi降低的持续时间反映疾病的严重程度；通过对经皮氧分压PtCO2测定，说明其能无创地反映周围组织的氧合情况。
Twenty-four patients with acute infection were tested for mucosal pH (pHi) and APACHE III scores at the same time. Percutaneous oxygen partial pressure was monitored in 12 of them. Results: After 1 hour of monitoring, the pHi of 2 organ dysfunction patients was significantly lower than that of the non-MODS patients, while there was no significant difference between APACHE Ⅲ scores. In 2 patients with organ dysfunction and 3 ~ 4 organ dysfunction patients, APACHE Ⅲ score there are significant differences, indicating early in the MODS pHi early reflection of organ damage, and by the duration of pHi to reflect the severity of the disease; by percutaneous oxygen partial pressure PtCO2 determination, indicating that it can non-invasive Reflects the oxygenation of the surrounding tissue.
