Introduction: Agonal respiration has been shown to be commonly associated with witnessed events, ventricular fibrillation, and increased survival during out-of-hospital cardiac arrest. There is little information on incidence of gasping for in-hospital cardiac arrest (IHCA). Our “Rapid Response Team” (RRT) missions were monitored between December 2010 and March 2015, and the prevalence of gasping and survival data for IHCA were investigated. Methods: A standardized extended in-hospital Utstein data set of all RRT-interventions occurring at the University Hospital Basel, Switzerland, from December 13, 2010 until March 31, 2015 was consecutively collected and recorded in Microsoft Excel (Microsoft Corp., USA). Data were analyzed using IBM SPSS Statistics 22.0 (IBM Corp., USA), and are presented as descriptive statistics. Results: The RRT was activated for 636 patients, with 459 having a life-threatening status (72%; 33 missing). 270 patients (59%) suffered IHCA. Ventricular fibrillation or pulseless ventricular tachycardia occurred in 42 patients (16% of CA) and were associated with improved return of spontaneous circulation (ROSC) (36 (97%) vs. 143 (67%; p<0.001)), hospital discharge (25 (68%) vs. 48 (23%; p<0.001)), and discharge with good neurological outcome (Cerebral Performance Categories of 1 or 2 (CPC) (21 (55%) vs. 41 (19%; p<0.001)). Gasping was seen in 128 patients (57% of CA; 46 missing) and was associated with an overall improved ROSC (99 (78%) vs. 55 (59%; p=0.003)). In CAs occurring on the ward (154, 57% of all CAs), gasping was associated with a higher proportion of shockable rhythms (11 (16%) vs. 2 (3%; p=0.019)), improved ROSC (62 (90%) vs. 34 (55%; p<0.001)), and hospital discharge (21 (32%) vs. 7 (11%; p=0.006)). Gasping was not associated with neurological outcome. Conclusions: Gasping was frequently observed accompanying IHCA. The faster in-hospital patient access is probably the reason for the higher prevalence compared to the prehospital setting. For CA on the ward without continuous monitoring, gasping correlates with increased shockable rhythms, ROSC, and hospital discharge.

Introduction. The single most important clinically relevant cause of global cerebral ischemia is cardiac arrest. The estimated rate of sudden cardiac arrest is between 40 and 130 cases per 100.000 people per year. Almost 80% of patients initially resuscitated from cardiac arrest remain comatose for more than one hour. One year after cardiac arrest only 10-30% of these patients survive with good neurological outcome. The ability to survive anoxic no-flow states is dramatically increased with protective and preservative hypothermia. The results of clinical studies show a marked neuroprotective effect of mild hypothermia in resuscitation. Material and Methods. In our clinic, 12 patients were treated with therapeutic hypothermia. A combination of intravascular and external method of cooling was used according to the ILCOR (International Liaison Committee on Resuscitation) guidelines. The target temperature was 33oC, while the duration of cooling was 24 hours. After that, passive rewarming was allowed. All patients also received other necessary therapy. Results. Six patients (50%) had a complete neurological recovery. Two patients (16.6%) had partial neurological recovery. Four patients (33.3%) remained comatose. Five patients (41.66%) survived, while 7 (58.33%) patients died. The main cause of cardiac arrest was acute myocardial infarction (91.6%). One patient had acute myocarditis. Conclusion. Mild resuscitative hypothermia after cardiac arrest improves neurological outcome and reduces mortality in comatose survivors. .

Background: Effective advanced life support is one of the important link in the chain of survival. In Japan, the emergency medical service (EMS) personnel can perform defibrillation, advanced airway management, intravenous access and administration of epinephrine as an advanced life support intervention for the treatment of out-of-hospital cardiac arrest (OHCA). However, whether these interventions performed by EMS improves neurological outcomes remains unclear. Objective: To evaluate predictors of favorable neurological outcome in patients suffering OHCA with ventricular fibrillation (VF) witnessed by an EMS personnel. Methods: The Fire and Disaster Management Agency (FDMA) of Japan developed a nationwide database of a prospective population-based cohort using an Utstein-style template for OHCA patients since January 2005. To evaluate data after the publication of Guideline2010, data from January 2011 to December 2015 of this database was used for the current analysis. A multivariate logistic-regression analysis was performed to assess factors associated with favorable neurological outcome (defined as Cerebral Performance Category 1 or 2) 1 month after cardiac arrest. Results: Of the 629,471 patients documented for the study period, 2,301 adult patients with an OHCA of cardiac origin and VF for the initial rhythm witnessed by an EMS personnel were included in the present analysis. The overall mortality was 49.6%. Rate of return of spontaneous circulation and favorable neurological outcome were 53.4% and 44.8%, respectively. High age (OR0.387, 95%CI0.316-0.472, p<0.001), delayed defibrillation (OR0.598, 95%CI0.493-0.723, p<0.001), advanced airway management (OR0.305, 95%CI0.223-0.413, p<0.001), administration of epinephrine (OR0.356, 95%CI0.213-0.585, p<0.001) and multiple attempts of defibrillation (OR0.484, 95%CI0.402-0.582, p<0.001) were negatively associated with favorable neurological outcome. Conclusion: In patients with VF witnessed by EMS personnel, resuscitation efforts should simply focus on early defibrillation and CPR without advanced interventions.

Introduction/Aim. The most important clinically relevant cause of global cerebral ischemia is cardiac arrest. Clinical studies showed a marked neuroprotective effect of mild hypothermia in resuscitation. The aim of this study was to evaluate the impact of mild hypothermia on neurological outcome and survival of the patients in coma, after cardiac arrest and return of spontaneous circulation. Methods. The prospective study was conducted on consecutive comatose patients admitted to our clinic after cardiac arrest and return of spontaneous circulation, between February 2005 and May 2009. The patients were divided into two groups: the patients treated with mild hypothermia and the patients treated conservatively. The intravascular in combination with external method of cooling or only external cooling was used during the first 24 hours, after which spontaneous rewarming started. The endpoints were survival rate and neurological outcome. The neurological outcome was observed with Cerebral Performance Category Scale (CPC). Follow-up was 30 days. Results. The study was conducted on 82 patients: 45 patients (age 57.93 ? 14.08 years, 77.8% male) were treated with hypothermia, and 37 patients (age 62.00 ? 9.60 years, 67.6% male) were treated conservatively. In the group treated with therapeutic hypothermia protocol, 21 (46.7%) patients had full neurological restitution (CPC 1), 3 (6.7%) patients had good neurologic outcome (CPC 2), 1 (2.2%) patient remained in coma and 20 (44.4%) patients finally died (CPC 5). In the normothermic group 7 (18.9%) patients had full neurological restitution (CPC 1), and 30 (81.1%) patients remained in coma and finally died (CPC 5). Between the two therapeutic groups there was statistically significant difference in frequencies of different neurologic outcome (p = 0.006), specially between the patients with CPC 1 and CPC 5 outcome (p = 0.003). In the group treated with mild hypothermia 23 (51.1%) patients survived, and in the normothermic group 30 (81.1%) patients died, while in the group of survived patients 23 (76.7%) were treated with mild hypothermia (p = 0.003). Conclusion. Mild therapeutic hypothermia applied after cardiac arrest improved neurological outcome and reduced mortality in the studied group of comatose survivors.
