ABSTRACT
Objective:To analyze and discuss the characteristics of cardiopulmonary and cerebral resuscitation (CPCR) in patients after out-of-hospital cardiac arrest (OHCA).Methods:The data of OHCA patients admitted to the directly-managed branch of the Wuxi Emergency Medical Center, covering the period from December 26, 2016, at 7:45 to August 26, 2022, at 7:45. The analysis included the first electrocardiogram (ECG), clinical characteristics, pre-hospital emergency measures, and follow-up conditions in the hospital. Based on the Glasgow-Pittsburgh cerebral function grading at discharge, patients were divided into a CPCR group (grades 1-2) and a non-CPCR group (grades 3-5). The study compared the basic conditions, resuscitation times, and vital signs after resuscitation between the two groups to evaluate the factors affecting CPCR.Results:A total of 6 040 OHCA cases were treated, 3 002 cases received pre-hospital resuscitation. The initial ECG indicated a shockable rhythm in 185 cases, with a shockable rhythm rate of 6.16%. There were 293 pre-hospital survivors, with a pre-hospital survival rate of 9.76%. 170 cases survived to be discharged, with a discharge survival rate of 5.66%. Ultimately, 44 cases achieved CPCR, accounting for 25.88% of the cases that survived to discharge. There were statistically significant differences in terms of first-witness treatment, defibrillable rhythm ratio, defibrillation, response to pain stimulation after return of spontaneous circulation (ROSC), spontaneous breathing, light reflex, pulse oxygenation, and blood pressure between the CPCR and non-CPCR groups (all P<0.05). The CPCR group showed significantly higher proportions than the non-CPCR group in the defibrillatable rhythm (75.00% vs. 10.44%), undergoing defibrillation (70.46% vs. 9.24%), having spontaneous breathing after ROSC (86.36% vs. 17.27%), and having oxygen saturation >92% with systolic blood pressure >90 mmHg (86.36% vs. 39.76%).There were statistically significant differences between the CPCR and non-CPCR groups in the time from cardiac arrest (CA) to doctor reception, CA to first defibrillation, CA to ROSC, and CA to discharge or in-hospital death (all P<0.05). Conclusions:The patients with successful pre-hospital resuscitation and finally cerebral resuscitation were characterized by short times from OHCA to first medical contact (FMC) and from FMC to ROSC, appropriate pre-hospital vital sign management accompanied by partial neurological recovery, and comprehensive in-hospital neurological prognosis assessment.
ABSTRACT
Cardiac arrest (CA) is the most serious clinical emergency situation and cardiopulmonary-cerebral resuscitation (CPCR) performed on site with high quality is the optional therapy for its management. It has been reported that prolonging the resuscitation time after 30-minute failed conventional cardiopulmonary resuscitation (CPR) could improve the in-hospital survival rate of CA patients, and how to improve the out-hospital survival rate and survival quality of these patients is a research hot focus at present. A male patient admitted to Emergency Center of Shihezi People's Hospital reported in Xinjiang in this study had two CAs. In 2002, he experienced Adams-Strokes syndrome due to acute myocardial infarction (AMI) and survived after 35-minute of successful CPR. The criminal vessel was judged to re-canalize clinically 2 hours after thrombolytic therapy with urokinase, and he was cured and discharged from hospital 25 days later. In 2016, the second CA insult him and after the 185-minute CPR, he survived but experienced the post-CA syndrome. As long as 7-day continuous mild hypothermia was performed, the temperature of displacement fluids in continuous blood purification (CBP) was adjusted to 35 ℃ to achieve the goal of brain protection management requirements. He was cured and discharged from hospital 75 days later. During the 9-month follow-up, he did well in activities of daily living and could engage in routine housework. This paper introduces the treatment process of the patient in detail, and provides experience for clinical treatment.
ABSTRACT
Objective To explore factors affecting cardiopulmonary and cerebral resuscitation in patients with cardiac arrest. Methods Logistic regression analysis was applied to analyze the factors affecting the survival rate of patients with cardiac arrest after cardiopulmonary resuscitation and return of spontaneous circulation (ROSC). Results 6 factors were related to the patient prognosis, including where the cardiac arrest took place, when the cardiopulmonary resuscitation (CPR) began, intervals of ROSC, pupils size, PRM (postresuscitation MODS) and age. multivariant analysis showed that PRM was the primary factor affecting the patients prognosis. Conclusion The time of taking CPR was the crucial factor affecting CPR success. PRM was an independent factor affecting the survival rate of the patients after ROSC. Rapid and effective resuscitation in the first place is the key to basic life support. More emphasis should be placed on the evaluation, monitoring and protection of the function of important organs after successful CPR.
