Đánh giá mối tương quan và sự phù hợp của PaCO2 với PcvCO2 và EtCO2 ở bệnh nhân sau mổ tim mở tại Bệnh viện Việt Đức

Abstract

Objective: To evaluate the correlation and the accuracy between PaCO₂ and PcvCO₂, and EtCO₂ in ICU patients after open heart surgery. Subject and method: An observational cross-sectional study, we studied 43 adult patients from 20 to 71 years, undergoing cardiac surgery with cardiopulmonary bypass from March 2018 to July 2018. In each patient, blood gas samples of artery and central vein were collected at 5 different periods, 6 hours apart in the department of cardiac resuscitation. Result: There has been a good correlation of PaCO₂ and PcvCO₂ with significant meaning (r = 0.79, p<0.05). There has been an accurcy between PaCO₂ and PcvO₂ at all periods, variations within acceptance limits of 10mmHg, although the difference has no significant meaning (p>0.05). Similary, there had been a good correlation of PaCO₂ and EtCO₂ with significant meaning (r = 0.66, p<0.05). There had been also an accurcy between PaCO₂ and EtCO₂ at all periods, variations within acceptance limits of 15mmHg (p>0.05). Conclusion: In post-open heart patients, there has been a good correlation and high accuracy between PaCO₂ with PcvCO₂ and EtCO₂ at all periods.
