RESUMEN
The new cardiopulmonary resuscitation (CPR) guideline emphasize the importance of chest compression, which was considered as the first step to CPR. The duration for CPR is usually limited to 30 minutes. With the development of new technology and evidence-based medicine, the success of extra longtime CPR has become possible, which is of great significance to some patients with cardiac arrest (CA), but the time limit has not been determined. On February 23rd in 2016, a 76-year-old female patient with respiratory and cardiac arrest who was on the third day after transurethral resection of bladder tumor (TUR-BT) was admitted to the intensive care unit of the General Hospital of Fushun Mining Bureau. On the basis of the comprehensive treatment measures such as ventilator support ventilation, physical cooling with ice cap, 1 mg adrenaline for intravenous injection, low molecular heparin of 5000 U for subcutaneous injection, and the continuous chest compression were carried out in a timely and effective manner for 125 minutes, which make the patient recover to sinus rhythm and her brain function recovered well without any sequelae, and follow-up of the patient in 1 year showed well. The key to success or failure of CPR depend on the patient's condition. If the patients in healthy, single cause, a good response to the resuscitation, the pulsation of the large artery can be seen now and then during the rescue, and the recovery of the spontaneous breathing, CPR should be kept on. In the process of CPR, individualized assessment of the disease progression without the 30-minute time limit, may benefit the patients in maximum. In the future clinical practice, we should actively explore more favorable evidence, so that CA patients can be rescued more.
RESUMEN
OBJECTIVES: This study was designed to assess cardiopulmonary resuscitation quality and rescuer fatigue when rescuers perform one or two minutes of continuous chest compressions. METHODS: This prospective crossover study included 148 lay rescuers who were continuously trained in a cardiopulmonary resuscitation course. The subjects underwent a 120-min training program comprising continuous chest compressions. After the course, half of the volunteers performed one minute of continuous chest compressions, and the others performed two minutes, both on a manikin model. After 30 minutes, the volunteers who had previously performed one minute now performed two minutes on the same manikin and vice versa. RESULTS: A comparison of continuous chest compressions performed for one and two minutes, respectively, showed that there were significant differences in the average rate of compressions per minute (121 vs. 124), the percentage of compressions of appropriate depth (76% vs. 54%), the average depth (53 vs. 47 mm), and the number of compressions with no errors (62 vs. 47%). No parameters were significantly different when comparing participants who performed regular physical activity with those who did not and participants who had a normal body mass index with overweight/obese participants. CONCLUSION: The quality of continuous chest compressions by lay rescuers is superior when it is performed for one minute rather than for two minutes, independent of the body mass index or regular physical activity, even if they are continuously trained in cardiopulmonary resuscitation. It is beneficial to rotate rescuers every minute when performing continuous chest compressions to provide higher quality and to achieve greater success in assisting a victim of cardiac arrest. .
