The association of acute hypercarbia and plasma potassium concentration during laparoscopic surgery: a retrospective observational study
It is uncertain whether increases in PaCO 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 PaCO during laparoscopic su...

Zusammenfassung: | It is uncertain whether increases in PaCO
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 PaCO
during laparoscopic surgery induce increases in plasma potassium concentrations and, if so, to determine the magnitude of such changes.
A retrospective observational study of adult patients undergoing laparoscopic abdominal surgery was perfomed. The independent association between increases in PaCO
and changes in plasma potassium concentration was assessed by performing arterial blood gases within 15 min of induction of anaesthesia and within 15 min of completion of surgery.
289 patients were studied (mean age of 63.2 years; 176 [60.9%] male, and mean body mass index of 29.3 kg/m
). At the completion of the surgery, PaCO
had increased by 5.18 mmHg (95% CI 4.27 mmHg to 6.09 mmHg) compared to baseline values (P |
