Abstract:
Purpose: To determine if CI measurements obtained in the chair position are similar to CI in the in-bed position.
Method: Using a convenience sample of cardiac surgical patients, a method-comparison study design was used to compare CI values obtained in 2 different body positions. Using a standard thermodilution technique for cardiac output measurement, CI was obtained once in the chair and in-bed positions. Measurement of CI in the second position was obtained immediately after measurement in the first position. Treatment order was randomly assigned. Bias and precision were calculated and graphed with the Bland-Altman method. Differences of ? 0.5 L/min/m2 were considered clinically significant. Student?s t-test was used to determine differences between CI values between the two positions, with a p of < 0.05 considered significant. Findings: A total of 27 postoperative cardiac surgical patients were studied. No statistical difference was found between CI measurements obtained in the chair and in-bed positions (t = 1.163, df=26, p=0.26). The average difference score for CI between the two positions was -0.07 ? 0.30 (bias ? precision) L/min/m2. Discussion: This study found that the difference between CI measurements obtained in-bed and in a bedside chair were small and statistically insignificant in 27 cardiac surgical patients. The clinical practice of putting hemodynamically stable, cardiac surgical patients back to bed prior to CI measurements may not be required to obtain accurate CI values.
