A modification of the anorectal manometric technique has been devised to improve its accuracy in 31 low-weight newborn and premature infants. The characteristics of the probes used allowed long recording sessions without any sedation of patients. The pressure records fit well the classically accepted requisites. All recordings showed spontaneous fluctuating waves and increased mean pressure in the aboral direction. The anorectal reflex was observed in all cases. Clear reflex waves were recorded in the most caudal third of the anal canal. In this zone the recording showed more distinct features with respect to fluctuation and relaxation waves than those located in more proximal parts. The validity of this technique is unquestionable from the view of the reliability of the recordings independent of the weight, gestational age, and birth age of the infants.
为提高对31例低体重新生儿和早产儿的准确性，设计了一种改良的肛肠测压技术。所用探头的特性使得无需对患者进行任何镇静即可进行长时间记录。压力记录符合经典认可的要求。所有记录均显示出自发性波动波，且向口侧方向的平均压力增加。所有病例均观察到肛肠反射。在肛管最尾侧三分之一处记录到清晰的反射波。在该区域，记录显示出与波动和松弛波相关的更明显特征，比位于更近端部分的特征更明显。从记录的可靠性来看，无论婴儿的体重、胎龄和出生年龄如何，该技术的有效性是毋庸置疑的。
