Standard versus Abdominal Lifting and Compression CPR

Abstract

Background. This study compared outcomes of abdominal lifting and compression cardiopulmonary resuscitation (ALP-CPR) with standard CPR (STD-CPR). Materials and Methods. Patients with cardiac arrest seen from April to December 2014 were randomized to receive standard CPR or ALP-CPR performed with a novel abdominal lifting/compression device. The primary outcome was return of spontaneous circulation (ROSC). Results. Patients were randomized to receive ALP-CPR (n=40) and STD-CPR (n=43), and the groups had similar baseline characteristics. After CPR, 9 (22.5%) and 7 (16.3%) patients in the ALP-CPR and STD-CPR groups, respectively, obtained ROSC. At 60 minutes after ROSC, 7 (77.8%) and 2 (28.6%) patients, respectively, in the ALP-CPR and STD-CPR groups survived (P=0.049). Patients in the ALP-CPR group had a significantly higher heart rate and lower mean arterial pressure (MAP) than those in the STD-CPR group (heart rate: 106.8 versus 79.0, P<0.001; MAP: 60.0 versus 67.3 mm Hg, P=0.003). The posttreatment PCO2 was significantly lower in ALP-CPR group than in STD-CPR group (52.33 versus 58.81, P=0.009). PO2 was significantly increased after ALP-CPR (45.15 to 60.68, P<0.001), but it was not changed after STD-CPR. PO2 after CPR was significantly higher in the ALP-CPR group (60.68 versus 44.47, P<0.001). There were no differences between genders and for patients who are > 65 or ≤ 65 years of age. Conclusions. The abdominal lifting and compression cardiopulmonary resuscitation device used in this study is associated with a higher survival rate after ROSC than standard CPR.
