摘要
应用餐后食管３小时ｐＨ监测技术临床检测２２例，其中正常对照组７例，反流症状组１５例。检测指标：反流指数（ＧＥＲＩ）、反流总时间（ＧＥＲＴ）、反流率（ＧＥＲＴ％）．结果表明：正常组各项指标均值均明显佩于症状组（Ｐ＜０．０５～０．０１）。以正常组各项指标的均值加２个标准差为阈值，判定病理性反流。结果症状组的阳性检出率达８０％，正常组为１４％（Ｐ＜０．０５）。
Esophageal pH was monitored fOr 3h dnter meal by using a minielectrodeconnected with pH meter. Among the 22 cases tested,15 cases sufferedfrom gastroesophageal reflux(GER)and 7 normal subjects served as. control. The resdlt showed that the valuc of reflux index(GERI),reflux total timc(RERT)and reflux rate (CERT%)in control group wea signicantly less thanthat in GER group (P<0.05～0.01). The mean value plus double standarddeviation in control group was regarded as the threshold value of pathologicalreflux. A posilive rate of 80% was obtained in GER group and 14%incontrol group (P<0.05).
