Abstract:
Objective To investigate the changes of electrolyte metabolism in patients undergoing moderate elective abdominal operation,and explore its relationship with postoperative complications.Methods The clinical data of 1117 inpatients (age ≥ 18 years) who had undergone moderate elective abdominal operation in the Department of General Surgery of Beijing Hospital from January 1,2011 to December 31,2011 were retrospectively analyzed.They received postoperative fasting for ≥ 3 days,and the preoperative liver function and renal function were normal.The perioperative electrolyte changes and clinical outcomes were recorded.For patients with normal preoperative electrolytes but abnormal postoperative electrolytes,its potential correlations with the postoperative infections and total complications were analyzed.Results The rates of abnormal postoperative electrolytes were as follows:potassium,24.1％ ; sodium,6.4％ ; chloride,27.6％ ; calcium,61.7％ ; magnesium,16.3％ ; and phosphorus,71％.The vast majority of ion levels were below the normal levels.The total complication rate was 19.7％ and the postoperative infection rate was 17.19％.Univariate logistic regression analysis showed that the postoperative total and infective complications were significantly associated with the increased (P =0.007) or decreased (P =0.007) serum potassium,the decreased serum sodium (P =0.016),the decreased serum phosphorus (P =0.004),and the decreased magnesium (P =0.049).Conclusions Electrolyte decrease is common after moderate elective abdominal operations.There is a certain correlation between postoperative electrolyte decrease and postoperative complications.Therefore,attention should be paid to maintain electrolyte balance during the perioperative period.
