Effect analysis of abdominal compression-decompression device in patients with cardiopulmonary resuscitation in pre-hospital first aid

Abstract

To investigate the effect of active abdominal compression-decompression cardiopulmonary resuscitation (AACD-CPR) in patients with pre-hospital respiratory and cardiac arrest. Forty-five patients with respiratory and cardiac arrest, and with contraindication of chest compression admitted to Baiyin Central Hospital of Gansu Province from March 2012 to September 2018 were enrolled, and they were divided into two groups according to random number table. AACD-CPR (abdominal compression-decompression group, n = 24) and cardiopulmonary resuscitation (CPR) with unarmed abdominal compression (unarmed abdominal pressure group, n = 21) were performed respectively. The success rate of rescue was observed in the two groups, and the changes in heart rate (HR), pulse oxygen saturation (SpO2) and blood pressure 30 minutes after CPR in patients with restoration of spontaneous circulation (ROSC) were observed. Among the 24 patients in the abdominal compression-decompression group, 5 patients (20.83%) had ROSC, and 2 patients (9.52%) had ROSC in 21 patients of the unarmed abdominal pressure group. The success rate of resuscitation in the abdominal compression-decompression group was significantly higher than that in the unarmed abdominal pressure group (P < 0.05). HR of ROSC patients at 30 minutes of CPR in abdominal compression-decompression group was significantly lower than that in unarmed abdominal compression group (bpm: 139.45±5.08 vs. 147.62±5.24, P < 0.05), and SpO2 and blood pressure were significantly higher than those in unarmed abdominal compression group with significant differences [SpO2: 0.92±0.03 vs. 0.85±0.03, systolic blood pressure (SBP, mmHg, 1 mmHg = 0.133 kPa): 118.23±3.26 vs. 98.51±3.10, diastolic blood pressure (DBP, mmHg): 60.10±2.50 vs. 56.36±2.45, all P < 0.05]. The effect of AACD-CPR was superior to that of unarmed abdominal pressure CPR, which had higher application value to rescue patients with respiratory and cardiac arrest with chest pressure contraindication.
