ABSTRACT
OBJECTIVE@#Since 2018, the surviving sepsis campaign recommended one-hour bundle therapy in septic shock patients. On the other hand, evidence for the effectiveness of bundle therapy has not been established. The object of this study was to determine the prognostic value of one-hour bundle completion in septic shock patients.@*METHODS@#This prospectively collected registry-based, retrospective observational study, between January 2016 and December 2018. A one-hour bundle in septic shock was defined by the serum lactate measurements, blood cultures, administration of antibiotics, and adequate fluid administration within one hour from emergency department admission. Eligible septic shock patients were included in the analysis, and the prognostic abilities of the completion of the one-hour bundle and each item were analyzed. The primary outcome was the 28-day mortality.@*RESULTS@#The study included 381 patients, and the overall 28-day mortality was 24.7%. The overall one-hour bundle completion rate was 11.3%, and each completion rate of serum lactate measurement, blood cultures, administration of antibiotics, and adequate fluid administration were 85.8%, 74.3%, 19.4%, and 48.6%, respectively. On the other hand, overall bundle completion as well as each bundle were not associated with the 28-day mortality except for adequate fluid administration (odds ratio [OR], 0.67 [95% confidence interval (CI), 0.30–1.50]; OR, 1.33 [95% CI, 0.66–2.70]; OR, 1.50 [95% CI 0.85–2.64]; OR, 1.17 [95% CI 0.66–2.07]; and OR, 0.54 [95% CI, 0.34–0.87], respectively). Multivariate logistic regression analysis showed that adequate fluid administration was independently associated with the 28-day mortality (OR, 0.22 [95% CI, 0.09–0.55]; P=0.001).@*CONCLUSION@#In this study, most of the one-hour bundle completions were not associated with 28-day mortality. Although adequate fluid administration was associated with the 28-day mortality, multicenter interventional study will be needed to generalize this result.
ABSTRACT
PURPOSE@#Non-benzodiazepine hypnotic drugs (including zolpidem) are associated with an increased risk of suicide and suicidal ideation. Considering the wide usage of zolpidem, this drug should be considered a possible etiology for stupor or coma in any patient exposed to this drug. However, there are no reports on zolpidem blood levels in emergency department patients in Korea. We therefore reviewed the analyzed data of a toxicology laboratory at one university affiliated hospital.@*METHODS@#The sex, age, chief symptoms, suspiciousness of poisoning, and presumption of poison were analyzed from January 2018 to June 2019. The detection frequency and level of zolpidem in the patient blood were compared to the mental changes presented, which is the main consequence of zolpidem.@*RESULTS@#A total of 229 toxicological analyses, requested to a toxicological laboratory at one university affiliated hospital, were reviewed. Among 229 patients, the mean age was 54.3±20.7 years old with 113 women and 116 men. 8.7% of patients have psychiatric illness and 39.7% were poisoned intentionally. The chief symptoms detected were: mental change 55.0%, gastrointestinal 14.4%, cardiovascular 10.5%, focal neurological 7.4%, respiratory 3.5%, none 8.7%, and unknown 0.4%. A request for detailed reports revealed that causative poisons were specified only in 20.1% cases. Zolpidem was detected in 22.3% cases (51/229), with median blood level 1.26 mg/L (interquartile 0.1, 5.06 mg/L) and urine 0.90 mg/L (interquartile 0.11, 5.6 mg/L). Furthermore, zolpidem was more frequently detected in toxicology analysis of patients where mental change was the primary symptom, as compared to other symptoms (32.5% vs. 9.7%, p<0.01).@*CONCLUSION@#This study reported the blood level of zolpidem in suspected poisoning patients admitted to the emergency department.
