GASTRIC AND LOWER ESOPHAGEAL SPHINCTER (LOS) PRESSURES IN EARLY-PREGNANCY BRITISH JOURNAL OF ANAESTHESIA BROCKUTNE, J. G., DOW, T. G., DIMOPOULOS, G. E., Welman, S., Downing, J. W., MOSHAL, M. G. 1981; 53 (4): 381-384

Abstract

Gastric (GP) and lower oesophageal sphincter pressures (LOSP) were measured in non-pregnant female volunteers (group I) and pregnant women with (group III) or without (group II) heartburn. Patients in early pregnancy had greater gastric pressures than group I. Mean barrier pressure (LOSP-GP) was significantly decreased in pregnant patients complaining of heartburn (group III) compared with groups I and II.
