According to several investigations ano-rectal manometry is a valuable diagnostic test of Hirschsprung's disease. In order to yield accurate results it requires a quiet, calm child who cooperates. In the few instances when this is not possible, general anaesthesia may be desirable. Manometric recordings of the internal and sphincter activity were therefore performed in 15 healthy children when awake and during general anaesthesia. The tonic activity at rest was significantly reduced during anaesthesia. Relaxations of the internal sphincter in response to rectal distension were recorded in all children both when awake and during anaesthesia. They were, however, significantly less pronounced during anaesthesia. These findings strongly suggest that ano-rectal manometry in the diagnosis of Hirschsprung's disease may be performed with advantage during general anaesthesia if the child does not cooperate when awake.
根据多项调查，肛门直肠测压法是诊断先天性巨结肠症的一项有价值的诊断测试。为了获得准确的结果，需要一个安静、平静且配合的儿童。在少数无法做到这一点的情况下，可能需要全身麻醉。因此，对15名健康儿童在清醒状态和全身麻醉期间进行了内括约肌和括约肌活动的测压记录。麻醉期间静息时的紧张性活动显著降低。所有儿童在清醒和麻醉期间均记录到直肠扩张时内括约肌的松弛情况。然而，麻醉期间这种松弛明显不那么显著。这些发现强烈表明，如果儿童在清醒时不配合，在全身麻醉期间进行肛门直肠测压法诊断先天性巨结肠症可能更有利。
