Hyperkalaemia may result in cardiac arrhythmias, muscle weakness or paralysis. The key objectives were to determine whether increases in <jats:italic>P<\/jats:italic>aCO<jats:sub>2<\/jats:sub> during laparoscopic surgery induce increases in plasma potassium concentrations and, if so, to determine the magnitude of such changes.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A retrospective observational study of adult patients undergoing laparoscopic abdominal surgery was perfomed. The independent association between increases in <jats:italic>P<\/jats:italic>aCO<jats:sub>2<\/jats:sub> and changes in plasma potassium concentration was assessed by performing arterial blood gases within 15\u00a0min of induction of anaesthesia and within 15\u00a0min of completion of surgery.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>289 patients were studied (mean age of 63.2\u00a0years; 176 [60.9%] male, and mean body mass index of 29.3\u00a0kg\/m<jats:sup>2<\/jats:sup>). At the completion of the surgery, <jats:italic>P<\/jats:italic>aCO<jats:sub>2<\/jats:sub> had increased by 5.18\u00a0mmHg (95% CI 4.27\u00a0mmHg to 6.09\u00a0mmHg) compared to baseline values (P\u2009&lt;\u20090.001) with an associated increase in potassium concentration of 0.25\u00a0mmol\/L (95% CI 0.20\u00a0mmol\/L to 0.31\u00a0mmol\/L, P\u2009&lt;\u20090.001). On multiple regression analysis, <jats:italic>P<\/jats:italic>aCO<jats:sub>2<\/jats:sub> changes significantly predicted immediate changes in plasma potassium concentration and could account for 33.1% of the variance (r<jats:sup>2<\/jats:sup>\u2009=\u20090.331, f(3,259)\u2009=\u200938.915, P\u2009&lt;\u20090.001).
