Key result
Continuous non-invasive arterial pressure monitoring provided mean arterial pressure measurements comparable to invasive arterial pressure monitoring in patients undergoing CABG surgery.
Why the study?
Accurate and continuous blood pressure measurement is crucial in cardiac surgery, prompting a comparison between continuous non-invasive arterial pressure and invasive arterial pressure monitoring after cardiopulmonary bypass weaning.
Does continuous non-invasive arterial pressure (CNAP) monitoring provide comparable mean arterial pressure measurements to invasive arterial pressure (IAP) monitoring in patients undergoing CABG surgery during weaning from CPB?

Does continuous non-invasive arterial pressure (CNAP) monitoring provide comparable mean arterial pressure measurements to invasive arterial pressure (IAP) monitoring in patients undergoing CABG surgery during weaning from CPB?
Continuous non-invasive arterial pressure (CNAP) monitoring provides accurate mean arterial pressure measurements comparable to invasive arterial monitoring during weaning from cardiopulmonary bypass in CABG patients.

May support CNAP as MAP alternative in CABG weaning; leaves open need for RCTs to confirm accuracy.
Background: Accurate and continuous measurement of arterial blood pressure is crucial in managing patients undergoing cardiac surgery to prevent complications and ensure better outcomes. Objectives: This study aimed to compare blood pressure monitoring using continuous non-invasive arterial pressure (CNAP) and invasive arterial pressure (IAP) methods after weaning from cardiopulmonary bypass (CPB). Methods: Blood pressure monitoring was conducted on 30 patients referred to Dr. Masih Daneshvari Hospital in Tehran for coronary artery bypass grafting (CABG) surgery. Measurements were taken every two minutes for 30 minutes after separation from CPB using both non-invasive CNAP and invasive IAP methods simultaneously. Data on systolic, diastolic, and mean arterial blood pressure (MAP) were collected and analyzed using SPSS statistical software. Results: The findings revealed no significant difference between the CNAP and IAP methods in monitoring MAP (P > 0.05). However, systolic blood pressure (SBP) measured by the IAP method was significantly higher than that measured by the CNAP method starting 10 minutes after weaning from CPB (P < 0.05). Conversely, diastolic blood pressure measured by the CNAP method was significantly higher than the IAP method at 2, 8, 10, 18, 20, and 22 minutes after CPB separation (P < 0.05). Conclusions: Continuous non-invasive arterial pressure is a non-invasive and continuous blood pressure monitoring method that can be considered an alternative to the IAP method for measuring MAP in CABG surgery patients during weaning from CPB.

Jahangirifard et al. (2024) conducted an observational in Coronary Artery Bypass Grafting (CABG) surgery (n=30). Continuous Non-invasive Arterial Pressure (CNAP) monitoring vs. Invasive Arterial Pressure (IAP) monitoring was evaluated on Mean arterial pressure (MAP) (MD 0.49, p=>0.05). Continuous non-invasive arterial pressure monitoring provided mean arterial pressure measurements comparable to invasive arterial pressure monitoring in patients undergoing CABG surgery.
