Enhanced Strategies through National Tri-temporal Analysis of Public Capacity Prepared for Laypersons' Cardiopulmonary Resuscitation

PURPOSE: Bystander cardiopulmonary resuscitation (CPR) and dissemination of its training are essential to improve the survival outcomes of sudden cardiac death. The purpose of this study was to investigate the tri-temporal trend analysis of the national CPR capacity variables and preparedness in a community. METHODS: This nationwide population-based study used structured questionnaire by a telephone survey for CPR in 2007 (n=1,029), in 2011 (n=1,000), and in 2015 (n=1,000). We used stratified cluster sampling to assess the impact of age, gender, and geographic regions. The contents in the questionnaire consisted of CPR awareness, self-efficacy for bystander CPR, prior training status, and willingness of public CPR training. RESULTS: The proportion of CPR awareness and its recent training experience (<2 years) increased from 89.0% and 14.6%, respectively, in 2007 to 88.5% and 18.7% in 2011, and finally to 94.8% and 30.6% in 2015 (both p for trend<0.001). More than 95% of respondents had agreed to mandatory CPR training acquiring a driver's license or CPR education in school. The awareness of Good Samaritan Law was increased from 20.5% in 2011 to 28.7% in 2015; however, the overall values were lower than the other CPR-related awareness and preparedness. CONCLUSION: In Korea, the trends of national CPR capacity index have been increasing during the past decade. However, the public awareness of the Good Samaritan Law was still low. We suggest that promoting the Good Samaritan Law should be the next step in preparing public CPR training in the future.

Traumatic Liver Injury: Factors Associated with Mortality / 대한중환자의학회지

BACKGROUND: We postulate that a delay in the implementation of hepatic arterial embolization for traumatic liver injury patients will negatively affect patient prognosis. Our work also seeks to identify factors related to the mortality rate among traumatic liver injury patients. METHODS: From January 2008 to April 2014, patients who had been admitted to the emergency room, were subsequently diagnosed with traumatic liver injury, and later underwent hepatic arterial embolization were included in this retrospective study. RESULTS: Of the 149 patients that underwent hepatic arterial embolization, 86 had the procedure due to traumatic liver injury. Excluding the 3 patients that were admitted to the hospital before procedure, the remaining 83 patients were used as subjects for the study. The average time between emergency room arrival and incidence of procedure was 164 min for the survival group and 132 min for the non-survival group; this was not statistically significant (p = 0.170). The average time to intervention was 182 min for the hemodynamically stable group, and 149 min for the hemodynamically unstable group, the latter having a significantly shorter wait time (p = 0.047). Of the factors related to the mortality rate, the odds ratio of the Glasgow Coma Score (GCS) was 18.48 (p < 0.001), and that of albumin level was 0.368 (p = 0.006). CONCLUSIONS: In analyzing the correlation between mortality rate and the time from patient admission to arrival for hepatic arterial embolization, there was no statistical significance observed. Of the factors related to the mortality rate, GCS and albumin level may be used as prognostic factors in traumatic liver injury.

A Case of Mental Change in a Patient Who Received a Zoletil Injection

Zoletil is a non-opioid, non-barbiturate animal anesthetic and proprietary combination of two drugs, a dissociative anesthetic drug, tiletamine, with the benzodiazepine anxiolytic drug, zolazepam. Zoletil has greater potency than ketamine. Zoletil is abused for recreational purposes, especially by people with easy access to medicine. However, in Korea, it is available over-the-counter. Here we report on a case of an 83-year-old woman who received injection of seven vials of "Zoletil 50" by her daughter and presented with an altered mental change. Her mental state was stupor and vital sign was hypotension, bradycardia. Her blood tests indicated metabolic and respiratory acidosis and hyperkalemia. She was treated with intravenous naloxone and flumazenil but was not responsive. She was admitted to the ICU and treated with supportive therapy. Her mental state showed transient recovery, however, her clinical manifestation worsened and she expired.
