摘要
目的比较Hamm及周寿生2组酸碱失衡预计代偿范围计算公式的差别及其合理性。方法将745份实测异常血气分析结果同时用2组公式判断其酸碱失衡类型，用Kappa检验2组公式的一致性。结果两组公式判断108份代谢性酸中毒一致率为70．4％（Kappa值0．41，P〈0．01）；判断132份代谢性碱中毒一致率为59．1％（Kappa值0．18，P〈0．05）；判断81份急性呼吸性酸中毒一致率为65．4％（Kappa值0．31，P〈0．01）；判断168份急性呼吸性碱中毒一致率为54．8％（Kappa值0．24，P〈0．01）；判断119份慢性呼吸性酸中毒一致率为67．2％（Kappa值0．41，P〈0．01）；判断137份慢性呼吸性碱中毒一致率为66．6％（Kappa值0．43，P〈0．01）。结论用Hamm和周寿生2组公式判断酸碱失衡类型存在明显差别，周寿生公式组转化后，其继发变化的最大预计代偿系数略高于其原始采纳的代偿系数。
Objective To compare the difference and rationalities between Harem and Zhou＇ s formulae for expected acid-base compensation in acid-base imbalance. Methods 745 cases of arterial blood gas analysis results of acid-base disorder were evaluated respectively by Hamm and Zhou＇ s formulae, and the concordance was judged. Results For metabolic acidosis （ 108 cases）, the concordance rate was 70. 4% between Hamm and Zhou＇ s （Kappa value = 0. 41,P 〈 0. 01 ） ;for metabolic alkalosis （ 132 cases）, the concordance rate was 59. 1% （ Kappa value =0. 18,P 〈0. 05） ;for acute respiratory acidosis（81 cases） ,the concordance rate was 65.43 % （Kappa value = 0. 31, P 〈 0. 01 ） ;for acute respiratory alkalosis （ 168 cases）, the concordance rate was 54. 8 % （ Kappa value = 0. 24%, P 〈 0. 01 ） ; for chronic respiratory acidosis （ 119 cases ）, the concordance rate was 67. 2% （ Kappa value =0. 41 ,P 〈0. 01 ） ;for chronic respiratory alkalosis（ 137 cases） ,the concordance rate was 66. 6% （ Kappa value =0. 43 ,P 〈0. 01 ）. Conclusion The difference between Harem and Zhou＇ s formulae for expected acid-base compensation in acid-base imbalance was obvious. The Zhou＇ s expected max compensation coefficient were slightly higher than the primary adopted compensation coefficient.
