عنوان انگلیسی Efficacy of the “Head-Up Position” in Returning Cardiopulmonary Bypass Blood to the Patient and Reducing the Required Blood Transfusion: A Randomized Trial
چکیده انگلیسی مقاله Background: All intraoperative strategies that may assist an anesthesiologist with lowering theblood transfusion rate must be considered. We assessed the efficacy of the 30° head-upposition at the end of cardiopulmonary bypass (CPB) in returning CPB reservoir blood topatients, reducing the transfusion rate, and conferring hemodynamic stability after thetransfer of patients to the intensive care unit (ICU).Methods: In a single-center clinical trial, 88 adult patients undergoing elective isolated coronaryartery bypass graft surgery were randomly allocated to the head-up group (n=44), in whichthe 30° head-up position was applied during separation from CPB, and the supine group(n=44), in which weaning from CPB was performed in the supine position. All the patientshad left ventricular ejection fractions > 35%. The primary end point was the returnedvolume of filtered CPB blood to the patients. The secondary outcome measures wereintraoperative and early postoperative hemodynamic parameters. Additionally, bloodproducts transfused during surgery and in the 1st 6 hours following ICU admission wererecorded.Results: There were no statistically significant differences in intraoperative and early postoperativehemodynamics between the 2 groups except in the returned blood volume to the patientsafter separation from CPB (714 ± 99 mL in the head-up position group vs 285 ± 78 mL inthe supine group; P = 0.0001). There were no significant differences between the 2 groupsregarding the transfused blood products during surgery and the 1st 6 hours following ICUadmission.Conclusions: Using the 30° head-up position at the end of CPB conferred a higher return of bloodto the patients but did not significantly reduce postoperative transfusion.
