Using continuous esophageal pH monitoring, we examined 40 asymptomatic babies to evaluate the influence of different positions (prone, supine, right and left side lying position) on gastroesophageal reflux (GER). Several parameters including percent of time with a pH < 4, numbers of reflux episode, numbers of reflux episode lasting more than 5 min, average duration of longest reflux and average pH were studied. All babies were born fullterm and were 1 to 14 days old (average: 4 days). Male to female ratio was 1.7:1. For all parameters, except for average pH, we obtained more favorable results in prone position (p < 0.05). Continuous esophageal pH monitor is a suitable technique to evaluate GER under physiologic circumstances.
我们采用连续食管pH监测法，对40名无症状婴儿进行了检查，以评估不同体位（俯卧位、仰卧位、右侧卧位和左侧卧位）对胃食管反流（GER）的影响。研究了几个参数，包括pH值<4的时间百分比、反流发作次数、持续超过5分钟的反流发作次数、最长反流的平均持续时间以及平均pH值。所有婴儿均为足月儿，年龄在1至14天之间（平均：4天）。男女比例为1.7:1。对于所有参数，除了平均pH值外，我们在俯卧位时获得了更有利的结果（p<0.05）。连续食管pH监测是一种在生理情况下评估GER的合适技术。
