OBJECTIVE
To assess the predictive value of a gastric intramucosal pH of less than 7.35 for mortality in surgical patients after supracoeliac aortic cross-clamping.
DESIGN
Open prospective clinical study.
SETTING
University hospital, The Netherlands.
SUBJECTS
Six patients who required temporary supracoeliac, and four patients who required temporary infrarenal, cross-clamping of the aorta.
MAIN OUTCOME MEASURES
Mortality and conventional measures of organ dysfunction correlated with gastric tonometry.
RESULTS
All 6 patients who required supracoeliac cross-clamping underwent a steep, and 5 patients a prolonged, decrease in the gastric intramucosal pH. The mean lowest gastric intramucosal pH in the supracoeliac group was 7.05 and in the infrarenal group 7.28. All patients recovered completely.
CONCLUSION
A pHig value below 7.35 does not seem to be a marker of mortality in patients who have undergone supracoeliac cross-clamping of the aorta.
目的
评估胃黏膜内pH值低于7.35对接受腹腔干上主动脉交叉钳夹术的外科患者死亡率的预测价值。
设计
开放性前瞻性临床研究。
地点
荷兰某大学医院。
研究对象
6例需要临时进行腹腔干上主动脉交叉钳夹术的患者，以及4例需要临时进行肾下主动脉交叉钳夹术的患者。
主要观察指标
死亡率以及与胃张力测定相关的器官功能障碍的传统指标。
结果
所有6例需要进行腹腔干上主动脉交叉钳夹术的患者胃黏膜内pH值均急剧下降，其中5例患者的胃黏膜内pH值持续下降。腹腔干上组患者的最低平均胃黏膜内pH值为7.05，肾下组为7.28。所有患者均完全康复。
结论
对于接受腹腔干上主动脉交叉钳夹术的患者，pH值低于7.35似乎并非死亡率的一个指标。
