ارتباط بین فشار PACO2 و PECO2 در طول CBP

عنوان انگليسی

The relationship between arterial pressure of carbon dioxide (PaCO2) and Endtidal CO2 (PECO2) during hypothermic cardiopulmonary bypass (CPB)

خلاصه انگلیسی

Background: Physicians have always wanted to perform exact medical tests in non-invasive ways. During a cardiac surgery, after the onset of cardiopulmonary bypass, the patient’s ventilation along with the patient’s heart rate could stop, and the task of the two vital organs is transferred to the pulmonary heart system, which acts to ensure the patient’s ventilation at defined intervals in the patient’s arterial gas analysis. This study was done to determine the relationship between PaCO2 and PECO2 in cardiopulmonary bypass (CPB). Methodology: In a cross-sectional study, a total of 30 patients referring to the heart surgery department of Ardabil City Hospital, who would undergo coronary artery bypass grafting without other illness, were included in the study. Arterial blood samples were taken, and the result was reported through the arterial blood gas device in the operating room. The PaCO2 was compared with PECO2. Data were analyzed by statistical methods in SPSS version 22. Results: Of all patients, 17 (56.67%) were males and 13 (43.33%) were females. The mean age of patients was 60 ± 11 years with an age range of 35–78 years. The mean of PaCO2 was 36.5 ± 4.13 mmHg and the mean of PECO2 was 31 ± 6.4 mmHg. The fresh gas flow (FGF) was 1.9 ± 0.7. There was a positive and significant correlation between FGF and PaCO2 and also between FGF and PECO2. Conclusion: Results showed that there was a significant relation between arterial PCO2 and oxygenator exhausted PCO2 during hypothermic CPB.
