Abstract:
Metabolic acidosis is often encountered in a sick neonate and intestinal duplication with heterotopic gastric mucosa is a well-established condition. We present a previously unreported relationship between neonatal metabolic acidosis, resulting from transperitoneal absorption of hydrochloric acid, and a ruptured non- communicating ileal duplication cyst with gastric mucosal heterotopia. The neonate recovered rapidly after resection of the ileal duplication. We present this case to highlight a rare but surgically correctable cause of neonatal metabolic acidosis.

Diagnosing Acidosis and Alkalosis
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and...

Respiratory Acidosis and Alkalosis
Respiratory acidosis occurs due to an increase in the partial pressure of carbon dioxide PCO2 in the blood. It often arises from shallow breathing or impaired gas exchange caused by...
