How does nasogastric suctioning contribute to metabolic alkalosis?
How does nasogastric suctioning contribute to metabolic alkalosis? Hydrogen ions may be lost through the kidneys or the GI tract. Vomiting or nasogastric (NG) suction generates metabolic alkalosis by the loss of gastric secretions, which are rich in hydrochloric acid (HCl). Whenever a hydrogen ion is excreted, a bicarbonate ion is gained in the extracellular space. What are complications of metabolic alkalosis? Complications. Alkalosis may lead to tetany, seizures, and decreased mental status. Metabolic alkalosis also decreases coronary blood flow and predisposes persons to refractory arrhythmias. Can tube feeding cause metabolic alkalosis? Loss of stomach acids. This is the most...
