以End-Tidal CO2評估CPR成效的臨床觀察
Clinical Assessment of End-Tidal CO2 Monitoring during Cardiopulmonary Resuscitation
摘要
有沒有一個簡便且有參考價值的指標可判斷CPR是否有效？近幾年陸續有學者指出P(下標 ET)CO2值正是這應一個數據。Capnometer近幾年成為開刀房的標準監測設備，我們才有機會針對這個問題做探討。 本報告搜集三年內在開刀房發生CPR的病例，經篩選後成功CPR有十個病例(Gr.A)，未成功七例(Gr.B)；將兩組在CPR前，CPR進行中段，後段P(下標 ET)CO2值做統計比較：CPR前兩組P(下標 ET)CO2值的對比（A對B）32.0±2.3mmHg對34.4±2.0mmHg(P＜0.05)，進行中段是12.0±1.6mmHg對12.7±0.7mmHg(P＞0.05)，後段是35.0±2.4mmHg對8.0±0.9mmHg(P＜0.001)具明顯統計差异。 由這些數據可以看出CPR進行中，心肺功能恢復時，P(下標 ET)CO2值有回到原值或更高的現象，反之則沒有；因此P(下標 ET)CO2值應是CPR有無成效的很好參考指標。

Is there any indicator which is both simple and of value in determining the effectiveness of ongoing cardiopulmonary resuscitation (CPR) efforts? ETCO2 monitoring has been suggested as a useful prognostic indicator of resuscitation effectiveness and survival. We attemted to evaluate this nodality. Cases receiving CPR in the operating rooms over the past three years were retrospectively reviewed and analyzed. Ten (Group A) out of seventeen patients were successfully resuscitated, but seven patients (Group B) were not. Comparing P(subscript ET)CO2 values in Group A and Group B before, during, and at the end of CPR, the results were 32±2.3 vs 34.4±2 mmHg (p＞0.05)12±1.6 vs 12.7±0.7 mmHg (p＞0.05), 35±2.4 vs 8±0.9 mmHg (p＜0.01), respectively. Data from this retrospective clinical assessment indicated that P(subscript ET)CO2 values rise immediately in patients whose cardiopulmonary function recovered with CPR. Low P(subscript ET)CO2 values were present when CPR was ineffective. Findings from ETCO2 monitoring correlated well with the effectiveness of CPR.
