Abstract
Lower esophageal sphincter pressures (LESP) are generally measured during esophageal motility studies using multilumen water perfused catheters. Because of the large size of this assembly, gagging occurs, sedation is required and acceptable tracings may not be obtained. We have compared a large catheter assembly (three 1.2 mm single lumen catheters bound together with a 4.0 mm total diameter) with a 1.2 mm single lumen catheter with 1.0 mm side orifice. Triplicate studies were obtained by perfusing the catheters with water at 1.3 cc/min and slowly withdrawing from the stomach to LES. LESP were obtained in 10 fullterm newborns 3 hours after feeding; infants were then sedated and 90 min. later triplicate studies repeated. LESP were as follows:
In two patients, gagging prevented the recording of adequate tracings from triple lumen catheters. Our data indicates that LESP can be successfully measured in the unsedated infant using a small single lumen catheter, and that higher pressures are obtained with the single lumen assembly.
