Standard versus Abdominal Lifting and Compression CPR

Abstract EN

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.
