“…Spontaneous gastric perforation is a rare entity in newborns, usually occurring in the first five days of life with highest reported incidence on the third day of life [4,5]. The commonly associated prenatal and perinatal risk factors as reported in order of frequency are prematurity, respiratory distress syndrome, birth asphyxia and resuscitation, premature rupture of membranes, breech delivery, caesarian delivery and twin delivery [4,6].…”

Extractwhen the infants were taking formula orally, the gastrostomy tubes were vented to a large coll~cting balloon aboveeach patient (15). o u r study presents an experimental model for studying gastric ~h~ air swallowed into the stomach was readily measured with this rupture in the newborn. w e showed that gastric rupture could be system (Fig. I ). Because spontaneous rupture usually occurs when produced in eight newborn rodents and in three puppies less than 10 an infant is supine (6), these infants were fed in this position, which days old after injection of 120 ml air at 100 mm Hg pressure in the also prevented eructation. Initially, the infants were fed standard rodents and ml air at 240 inin Hg pressure in the puppies. formula, but after two gastrostomy tubes partially obstructed, Gastric rupture occurred with animals supine and with approxi-they were fed with sugar water only.

“…In addition, eructation may be in fluenced by posture. The oesophagus enters the superior-posterior aspect of the stomach; thus, lying supine causes a fluid layer to form over the gastric oesophageal junction and thereby prevents belching [43]. The frequent development of rapid, massive, gaseous dis tension of the intestine during surgical and x-ray procedures performed in the supine po sition probably results from the combination of nervous air sucking and a posture that favours movement of air into the duodenum.…”
