摘要
目的:确定侧卧位之间终潮二氧化碳的差异对肺栓塞预测的存在和重要性。材料与方法:32例年龄为65.7±14.4 (16M, 16F)的肺栓塞患者和15例年龄为56.7±20.3 (10M, 5F)的排除肺栓塞患者分别采用仰卧位、左右侧卧位进行肺栓塞造影。左右卧位末潮二氧化碳浓度差值的绝对值称为δ指数。收集了人口统计学和临床数据。结果:肺栓塞患者的delta指数明显高于非肺栓塞患者:4 (3-5.5)mmHg vs 1 (1-2) mmHg p<0.001。δ指数曲线下面积为0.92;95% CI 0.83-1.0 p3mmhg预测PE的敏感性和特异性分别为66%和100%。结论:肺栓塞患者体位改变,终潮二氧化碳浓度变异性增加。
THE DELTA INDEX – THE DIFFERENCE BETWEEN END TIDALCARBON DIOXIDE CONCENTRATION IN RIGHTAND LEFT LATERAL DECUBITUS POSITION– COULD PREDICT PULMONARY EMBOLISM –PRELIMINARY RESULTS
Aim: To determine the presence and the importance of a difference in end tidal carbon dioxide between lateral decubitus positions for pulmonary embolism prediction.
Material and methods: There were 32 patients aged 65.7±14.4 (16M, 16F) with pulmonary embolism and 15 patients aged 56.7±20.3 (10M, 5F) with excluded pulmonary embolism Capnography was performed in supine, left and right lateral decubitus position. The absolute value of the difference in end tidal carbon dioxide concentration between left and right decubitus position was called the delta index. Demographics and clinical data were collected.
Results: The delta index was significantly higher in patients with pulmonary embolism vs those with excluded pulmonary embolism: 4 (3-5.5) mmHg vs 1 (1-2) mmHg p<0.001. Area under curve for the delta index was 0.92; 95% CI 0.83-1.0 p 3 mmHg to predict PE the sensitivity and specificity was 66% and 100%, respectively.
Conclusions: The patients with pulmonary embolism had increased variability of end tidal carbon dioxide concentration while changing their position.
