腹部择期手术前后电解质变化及术后早期补钾对胃肠功能的影响

为观察腹部择期手术前后电解质变化及早期补钾对胃肠功能恢复的影响，对６９例患者术前和术后电解质水平进行了测定，并观察了术后不同时间补钾者的胃肠功能恢复情况。结果：术后血Ｋ＋、Ｎａ＋、Ｃｌ－水平均较术前有明显降低（Ｐ＜０．０５），但仍在正常值范围，而血Ｃａ２＋及血Ｍｇ２＋手术前后无显著变化；术中输血量与血Ｋ＋变化无明显相关性；术后早期补钾者胃肠功能恢复快。本组资料结果提示：只要肾功能正常，术中输血不会引起高血钾，因此术后第１天可开始见尿补钾

ELECTROLYTE CHANGES BEFORE AND AFTER SCHEDULED ABDOMINAL SURGERY AND THE EFFECT OF PROMPT POTASSIUM SUPPLEMENT ON GASTROINTESTINAL FUNCTIOIN

In order to observe electrolyte changes before and after scheduled abdominal surgery and effect of prompt potassium supplement on the recovery of gastrointestinal function, electrolytes in 69 patients were tested before and after surgery, and the recovery of the gastrointestinal function was observed.The results showed that after surgery the levels of K , Na and Cl - were decreased dramatically ( P <0.05) but still within the normal range, with no distinctive change in Ca 2 and Mg 2 . No correlation between the amount of blood transfusion and potassium was detected. Prompt potassium supplement contributed to the quick recovery of gastrointestinal function.This suggests that with normal renal function, blood transfusion during the operation will not cause hyperkalemia, potassium supplement might begin on the first day when the patient begins to urinale.
