老年急腹症手术前后血气变化观察

Observation of Blood Gas Changes before and after Operations on Elderly Patients for Acute Abdomen

取老年急腹症38例,作术前后血气分析检查。并取同期同病种青中年病例51例作对照。发现老年组更易、更早出现酸碱失衡。低氧血症也更严重。与青中年组相较差异呈显著性。碱中毒及复合型酸碱失衡发生率高也是老年急腹症的特点。并探讨这些临床现象的机制及处理措施。提出血气分析是老年急腹症酸碱失衡的有效监测手段,并可作为老年急腹症时定夺手术的动态指标之一。

Analysis of blood gas was made before and after operations on 38 eider- ly patients with acute abdomen and was compared with 51 case of the same disease in the same stage in young and middle-aged patients.It was found that acidaemia and alkalemia occurred more easily and earlier in the aged group and the low oxygen blood disease more serious.There were re- markable differences compared with the other two groups.A high incidence of alkalemia and complex acidaemia and alkalemia was also the feature of acute abdomen in elderly patients. The mechanisms of these clinical signs and measures are discussed.It is concluded that blood gas analysis is an effective monitor measure for aci- dity and alkalinity balance in elderly patients with acute abdomen, so it can be one of the dynamic quotos for the decisions before the opera- tion.
