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.

Effect of Active Abdominal Compression-Decompression Cardiopulmonary Resuscitation on Oxygen Metabolism and Prognosis in Patients with Cardiac Arrest

“…Previous studies have shown that compared with AACD-CPR, STD-CPR can provide higher MAP [22]. In this study, although MAP of STD-CPR group was slightly higher, but the AACD-CPR group in CaO2, DO2, pH value.…”

Effect of Oxygen Pneumoperitoneum on Hypoxia Tolerance in Beagle Dogs: An Experimental Study

“…[22] , and the pressure was set at 12cmH 2 O (model: PG120, Aesculap Inc., Tuttlingen, Germany). Abdominal wall lifting and compression [23] was performed at a frequency of 60bpm, a ratio of 1:1, and a strength of 50N. Arterial blood gas (ABG) analyses were performed at baseline and at 6, 7, 8, 9, and 10 minutes, respectively, after the endotracheal tube was clamped, as well as at the time of asphyxia termination(model: GEM Premier 3000, Instrumentation Laboratory, Lexington, MA, USA).…”

Evaluation of Abdominal Compression-Decompression Combined With Chest Compression CPR Performed by a New Device: Is the Prognosis Improved After This Combination CPR Technique?

“…Z α / 2 and Z β are the upper (α /2)th and βth percentiles of the standard normal distribution, respectively. In another similar research, Sisen Zhang et al calculated the minimum sample size with a p t value of 0.21 and a p c value of 0.48 [12] . In our study, we determined the expected difference in not only the proportion of return of spontaneous circulation rate, but also the neurological function and the survival between two groups in the sample size estimation.…”

“…All methods were carried out following relevant regulations and guidelines. The effectiveness, safety, and stability of the abdominal compression-decompression device used in this study have been veri ed in human experiments [11,12] .…”

“…In addition, this method is mainly performed manually and lacks any objective and visual parameters, such as the force or depth of the compression-decompression, and it can be di cult to perform this technique accurately. An abdominal CPR compression-decompression instrument, as an external and easy-to-use device, has the potential to be useful with out-of-hospital emergency medical services [11,12] , and it is worth investigating the combination of both conventional chest and abdominal compression-decompression techniques to determine whether there is a better prognosis resulting from the use of this combination.…”
