The association of acute hypercarbia and plasma potassium concentration during laparoscopic surgery: a retrospective observational study.

ABSTRACT:

Background

It is uncertain whether increases in PaCO₂ during surgery lead to an increase in plasma potassium concentration and, if so, by how much. Hyperkalaemia may result in cardiac arrhythmias, muscle weakness or paralysis. The key objectives were to determine whether increases in PaCO₂ during laparoscopic surgery induce increases in plasma potassium concentrations and, if so, to determine the magnitude of such changes.

Methods

A retrospective observational study of adult patients undergoing laparoscopic abdominal surgery was perfomed. The independent association between increases in PaCO₂ and changes in plasma potassium concentration was assessed by performing arterial blood gases within 15 min of induction of anaesthesia and within 15 mi
