AbstractTwenty-seven patients admitted for cholecystectomy were matched for age and sex in three groups for different perioperative fluid therapies over a period of 3 days. Group I was given an acetated half-isotone "balanced" saline solution with the addition of 2.5% glucose, Group II an acetated Ringer solution and Group III an isotonic glucose solution. Percutaneous muscle biopsies were performed before and on the third day after surgery for the determination of water content and the concentration of sodium, potassium, magnesium and chloride in skeletal muscle. The cumulative balance of sodium and potassium was measured daily during the study. In all three groups a significant increase in the total muscle water content was demonstrated. The concentration of sodium and chloride in skeletal muscle increased significantly in Groups II and III, whereas the concentration of potassium decreased in all groups. The cumulative sodium balance was positive in Groups I and II; the potassium balance was negative in all groups. In conclusion, the patients given the balanced saline solution showed the least change in water content and electrolyte concentrations in skeletal muscle.
