Aortic balloon Assisted resuscitation group
Traditional cardiopulmonary resuscitation group
Esophageal cooling group
Traditional cooling group
The aortic balloon-assisted resuscitation group uses aortic balloon occlusion technology on the basis of the traditional resuscitation mode, that is, when the cardiopulmonary resuscitation begins, the aortic balloon catheter is quickly punctured and inserted to the distal end of the aortic area I via ultrasound. (Septum level), then continue to inflate the balloon to block the aortic blood flow until the end of the cardiopulmonary resuscitation to deflate the balloon and remove the balloon catheter.
The traditional cardiopulmonary resuscitation group uses the traditional manual chest compression mode, that is, referring to the latest version of the cardiopulmonary resuscitation guidelines, manual chest compressions are performed under the monitoring of the compression quality feedback device to ensure that the compression depth is 5-6cm, the frequency is 100-120 times/min, Conditions such as a fixed compression position and sufficient chest wall rebound.
The esophageal cooling group adopts a new transesophageal cooling method, that is, an esophageal cooling catheter is placed after resuscitation in patients with cardiac arrest, and then a small temperature-controlled water circulation system is continuously perfused with 4℃ cold water. After the patient's body temperature reaches the target temperature of 33℃, the temperature is adjusted Control the water circulation system to maintain the target body temperature of (33±0.5)°C for 24 hours, and then reheat to (37±0.5)°C normal body temperature at a rate of 0.25-0.5°C/h and maintain it for 24 hours.
The traditional cooling group uses the traditional body surface ice blanket cooling method, that is, the patients with cardiac arrest lie on the temperature control blanket after resuscitation, and then use the ice blanket host to continuously infuse the temperature control blanket with 4℃ cold water, and wait until the patient's body temperature reaches the target temperature of 33℃ After that, adjust the ice blanket host to control the circulating water temperature to maintain the target body temperature of (33±0.5)°C for 24 hours, and then reheat to the normal body temperature of (37±0.5)°C at a rate of 0.25-0.5°C/h and maintain it for 24 hours.
