ABSTRACT

Electrical Accidents Abstract: When persons seek medical help after an electrical injury, physicians have to inquire on the type (AC/DC) and strength of current (>1000V is considered "high voltage") as well as the exact circumstances (loss of consciousness, falls) of the accident. In the advent of high-voltage accidents, loss of consciousness, arrhythmias, abnormal ECG or elevated troponin levels, in-hospital rhythm monitoring is warranted. In all other cases, the type of extra cardiac injury primarily directs the management. Superficial skin marks may disguise more extensive thermal injuries of inner organs.

ABSTRACT

AIM OF THE STUDY: Evaluation of the treatment, epidemiology and outcome of cardiac arrest in the television franchise Star Trek. METHODS: Retrospective cohort study of prospective events. Screening of all episodes of Star Trek: The Next Generation, Star Trek: Deep Space Nine and Star Trek: Voyager for cardiac arrest events. Documentation was performed according to the Utstein guidelines for cardiac arrest documentation. All adult, single person cardiac arrests were included. Patients were excluded if cardiac arrest occurred during mass casualties, if the victims were annihilated by energy weapons or were murdered and nobody besides the assassin could provide first aid. Epidemiological data, treatment and outcome of cardiac arrest victims in the 24th century were studied. RESULTS: Ninety-six cardiac arrests were included. Twenty-three individuals were female (24%). Cardiac arrest was witnessed in 91 cases (95%), trauma was the leading cause (n = 38; 40%). Resuscitation was initiated in 17 cases (18%) and 12 patients (13%) had return of spontaneous circulation. Favorable neurological outcome and long-term survival was documented in nine patients (9%). Technically diagnosed cardiac arrest was associated with higher rates of favorable neurological outcome and long-term survival. Neurological outcome and survival did not depend on cardiac arrest location. CONCLUSION: Cardiac arrest remains a critical event in the 24th century. We observed a change of etiology from cardiac toward traumatic origin. Quick access to medical help and new prognostic tools were established to treat cardiac arrest.

ABSTRACT

INTRODUCTION: The aim of the study was to evaluate the epidemiology and outcome after cardiac arrest caused by intoxication. METHODS: A retrospective analysis of 1991 to 2010 medical record of patients experiencing cardiac arrest caused by self-inflicted, intentional intoxication was performed. The setting was an emergency department of a tertiary care university hospital. The primary end point was the presentation of epidemiologic data in relation to favorable neurologic outcome, defined as cerebral performance categories 1 or 2 and 180-day survival. Furthermore, the patients were subdivided into a single-substance and polysubstance group, depending on the substances causing the intoxication. RESULTS: Of 3644 patients admitted to our department, 99 (2.7%) with a median age of 26 (interquartile range, 19-42) years (37% female) were included. Cardiac arrest was witnessed in 62 cases (63%). Eleven patients (11%) received basic life support by bystanders, and 11 (11%) had a shockable rhythm in the initial electrocardiogram. The combined end point "good survival" was achieved by 34 patients (34%). Cardiac arrest occurred out of hospital in 73 patients (74%) and in-hospital in 26 patients (26%). A single substance causing the intoxication was found in 56 patients (56%). Opiates were the leading substance, with 25 patients (25%) using them. CONCLUSION: Cardiac arrest caused by intoxication is found predominately in young patients. Overall, favorable neurologic survival was achieved in 34%. Opiate-related cardiac arrest was associated with poor survival and a high incidence of neurologic deficits.

ABSTRACT

AIM: Emergency cardiopulmonary bypass (E-CPB) is an advanced and rarely used procedure for patients in cardiac arrest that do not regain restoration of spontaneous circulation with standard resuscitation methods. The feasibility, safety and outcome of the intervention with E-CPB in cardiac arrest situations at our department have been evaluated. METHODS: Clinical presentation, time intervals, diagnosis and outcome of all patients who received E-CPB at an emergency department of a tertiary care university hospital were evaluated. Patient charts were reviewed regarding cardiac arrest variables and treatment data of all patients from 1993 to 2010. RESULTS: E-CPB was performed in 55 patients. Of all patients, 33 (60%) were male and the median age was 32 years (IQR 24-44). In all cases cardiac arrest was witnessed. The first recorded ECG rhythm showed pulseless electric activity in 23 (42%), ventricular fibrillation in 21 (38%) and asystole in 11 (20%) patients. Cardiac arrest occurred out-of-hospital in 33 (60%) patients. The median duration of CPR before performing E-CPB was 86 min (IQR 69-121). The median 'cannulation'-time was 33 min (IQR 21-45) and the duration on bypass was 311 min (IQR 161-953). Cardiac causes of arrest were found in 19 (35%) patients. Eight patients (15%) survived to 6 months with good neurological outcome. CONCLUSION: E-CPB for cardiac arrest is feasible and safe. In this seemingly desperate patient population after prolonged cardiac arrest, we observed a high survival rate of 15%. E-CPB is a meaningful treatment option, which should be considered more often and earlier.

ABSTRACT

AIM OF THE STUDY: To question the beneficial effects of the recommended early percutaneous coronary intervention (PCI) after out-of-hospital cardiac arrest on 30-day survival with favourable neurological outcome. METHODS: Prospectively collected data of 1277 out of hospital cardiac arrest patients between 2005 and 2010 from a registry at a tertiary care university hospital were used for a cohort study. RESULTS: In 494 (39%) arrest patients ST-segment elevation was identified in 249 (19%). Within 12h after restoration of spontaneous circulation catheter laboratory investigations were initiated in 197 (79%) and PCI in 183 (93%) (78% got PCI in less than 180 min). Adjustment for a cumulative time without chest compressions <2 min, initial shockable rhythm, cardiac arrest witnessed by healthcare professionals, and a higher core temperature at time of hospitalization reduced the effect of PCI on favourable neurological outcome at 30 days (OR 1.40; 95% CI, 0.53-3.7) compared to the univariate analysis (OR 2.52; 95% CI, 1.42-4.48). CONCLUSION: This cohort study failed to demonstrate the beneficial effects of PCI as part of post-resuscitation care on 30-day survival with a favourable neurological outcome.

ABSTRACT

OBJECTIVE: Studies showing the effectiveness of therapeutic hypothermia (32-34°C) in postcardiac arrest patients have been criticized because of patients with elevated body temperature (>37.5°C) in the noncooled control group. Thus, the effects of spontaneous normothermia (<37.5°C) compared with mild therapeutic hypothermia were studied. DESIGN: Retrospective chart review from 1991 to 2010. PATIENTS: Witnessed out-of-hospital arrest, presumed to be of cardiac origin, aged 18 to 80 yrs and with a Glassgow Coma Scale score of <8 at admission. INTERVENTIONS: Patients with sustained restoration of spontaneous circulation who did not receive therapeutic hypothermia and never exceeded 37.5°C during the 36 hrs postcardiac arrest were compared with patients who received mild therapeutic hypothermia. MEASUREMENTS AND MAIN RESULTS: The primary end point was a favorable neurological outcome, defined as Cerebral Performance Categories 1 or 2; the secondary end point was overall survival to 180 days. Significantly more patients in the hypothermia group had Cerebral Performance Categories 1 or 2 (hypothermia: 256 of 467 [55%] vs. normothermia: 69 of 165 [42%]) and survived for >180 days (hypothermia: 315 of 467 [67%] vs. normothermia: 79 of 165 [48%]). The propensity score adjusted risk ratio for good neurological outcome of patients undergoing hypothermia treatment was 1.37 (confidence interval 1.09-1.72, p≤.01) and for dying within 180 days was 0.57 (confidence interval 0.44-0.73, p≤.01) compared to normothermia. CONCLUSIONS: Therapeutic hypothermia is associated with significantly improved neurological outcome and 180-day survival compared to spontaneous normothermia in cardiac-arrest patients.

ABSTRACT

AIM: Mild therapeutic hypothermia has shown to improve long-time survival as well as favorable functional outcome after cardiac arrest. Animal models suggest that ischemic durations beyond 8 min results in progressively worse neurologic deficits. Based on these considerations, it would be obvious that cardiac arrest survivors would benefit most from mild therapeutic hypothermia if they have reached a complete circulatory standstill of more than 8 min. METHODS: In this retrospective cohort study we included cardiac arrest survivors of 18 years of age or older suffering a witnessed out-of-hospital cardiac arrest, which remain comatose after restoration of spontaneous circulation. Data were collected from 1992 to 2010. We investigated the interaction of 'no-flow' time on the association between post arrest mild therapeutic hypothermia and good neurological outcome. 'No-flow' time was categorized into time quartiles (0, 1-2, 3-8, >8 min). RESULTS: One thousand-two-hundred patients were analyzed. Hypothermia was induced in 598 patients. In spite of showing a statistically significant improvement in favorable neurologic outcome in all patients treated with mild therapeutic hypothermia (odds ratio [OR]: 1.49; 95% confidence interval [CI]: 1.14-1.93) this effect varies with 'no-flow' time. The effect is significant in patients with 'no-flow' times of more than 2 min (OR: 2.72; CI: 1.35-5.48) with the maximum benefit in those with 'no-flow' times beyond 8 min (OR: 6.15; CI: 2.23-16.99). CONCLUSION: The beneficial effect of mild therapeutic hypothermia increases with cumulative time of complete circulatory standstill in patients with witnessed out-of-hospital cardiac arrest.

ABSTRACT

AIM OF THE STUDY: The aim of this study was to study exercise-related cardiac arrests on the tennis court and investigate the impact of early initiation of cardiopulmonary resuscitation on survival rate and outcome. METHODS: This study was based on the cardiac arrest registry of the Department of Emergency Medicine at the General Hospital Vienna in Austria. Between February 1993 and April 2010 non-professional athletes were identified, who experienced exercise-related cardiac arrest on the tennis court. The analysis was accomplished using descriptive statistics. Results are presented as mean±standard-deviation or median and interquartile range (IQR). RESULTS: The subjects (n=27) were predominantly male (96%) with a median age of 58 years; 52% of all patients had underlying cardiovascular risk factors. All cardiac arrests were witnessed. Bystander CPR was documented in 17 cases (63%). Median time from collapse to initiation of CPR was 1(IQR 0-2) minute. Ventricular fibrillation was the initial rhythm in 25 patients (93%) and in 3 an automated external defibrillator was used by bystanders. Twenty-four patients (89%) had return of spontaneous circulation before admission to the hospital and four (15%) followed verbal commands thereafter. The survival rate at 6 months was 82% with 20 patients (74%) having favourable neurologic outcome. CONCLUSIONS: Cardiac arrest on the tennis court is a predominantly witnessed event with a respectively high rate of bystander CPR, which reflects in a high successful survival rate.
