Clinical outcomes after a single induction dose of etomidate versus ketamine for emergency department sepsis intubation: a randomized controlled trial.

Patients with sepsis often require emergency intubation. In emergency departments (EDs), rapid-sequence intubation with a single-dose induction agent is standard practice, but the best choice of induction agent in sepsis remains controversial. We conducted a randomized, controlled, single-blind trial in the ED. We included septic patients who were aged at least 18 years and required sedation for emergency intubation. Patients were randomly assigned by a blocked randomization to receive 0.2-0.3 mg/kg of etomidate or 1-2 mg/kg of ketamine for intubation. The objectives were to compare the survival outcomes and adverse events after intubation between etomidate and ketamine. Two hundred and sixty septic patients were enrolled; 130 patients/drug arm whose baseline characteristics were well balanced at baseline. In the etomidate group, 105 patients (80.8%) were alive at 28 days, compared with 95 patients (73.1%) in the ketamine group (risk difference [RD], 7.7%; 95% confidence interval [CI], - 2.5 to 17.9%; P = 0.092). There was no significant difference in the proportion of patients who survived at 24 h (91.5% vs. 96.2%; P = 0.097) and survived at 7 days (87.7% vs. 87.7%; P = 0.574). A significantly higher proportion of the etomidate group needed a vasopressor within 24 h after intubation: 43.9% vs. 17.7%, RD, 26.2% (95% CI, 15.4 to 36.9%; P < 0.001). In conclusion, there were no differences in early and late survival rates between etomidate and ketamine. However, etomidate was associated with higher risks of early vasopressor use after intubation.

Retention of Basic-Life-Support Knowledge and Skills in Second-Year Medical Students.

PURPOSE: Basic life support (BLS) training is crucial in improvement of cardiopulmonary resuscitation (CPR) outcomes. Many studies have demonstrated improvement of skills after BLS training but the skills significantly decrease over time. Our study aimed to evaluate the retention of knowledge and skills after training following 2010 BLS guidelines in second year medical students at Faculty of Medicine, Thammasat University. MATERIALS AND METHODS: One hundred and forty-nine second-year medical students were enrolled in the prospective cohort study. Participants were tested for knowledge and skills of BLS prior to training (pre-test), immediately after training (post-test) and six months after training (retention test). RESULTS: The mean scores of pre-test, immediate post-test and retention-test were 8.52 (SD 1.88), 12.12 (SD 1.52) and 10.83 (SD 1.95), respectively. Improvement in knowledge score post-test and retention test were 3.60 (95% CI 3.22,3.99 P<0.001) and 2.31 (95% CI 1.92,2.70 P<0.001) respectively, compared with pre-test score. In post-test, detection skill, activation skill and compression skill were improved 1.67 (95% CI 1.28,2.19 P<0.001), 5.15 (95% CI 3.41,7.77 P<0.001) and 3.88 times (95% CI 2.24,6.71 P<0.001) compared with pre-test evaluation. Comparison between retention test and pre-test was improved detection skill 1.72 (95% CI 1.31,2.26 P<0.001), activation skill 4.4 (95% CI 2.93,6.75 P<0.001) and compression skill 2.56 (95% CI 1.44,4.57 P=0.001). Knowledge decreased 1.29 times in retention test compared with post-test (95% CI -1.67,0.92 P<0.001). In retention test, detection skill increased 1.03 times (95% CI 0.81,1.29 P = 0.810), activation skill decreased 0.86 times (95% CI 0.98,1.10 P =0.24) and compression skill decreased 0.66 times (95% CI 0.45,0.98 P=0.04) compared with post-test. CONCLUSION: Knowledge and skills of BLS significantly improved after training in second year medical students. However, the knowledge decreased at 6 months after training although the BLS skills still remained.

Predictors of in-hospital cardiac arrest within 24 h after emergency department triage: A case-control study in urban Thailand.

OBJECTIVE: This study describes the predictors of in-hospital cardiac arrest (IHCA) within 24 h of ED triage and evaluates their ability to predict patients at risk of IHCA. METHODS: A case-control study was conducted in the ED. 'Cases' are herein defined as hospitalised patients who experienced IHCA within 24 h after ED triage. The exclusion criteria were those younger than 16 years old, cases of traumatic arrest, or had do-not-resuscitate orders. The controls were adults, non-traumatic cases, who did not experience IHCA within 24 h of ED triage. A multivariable regression model was used to identify significant predictors of IHCA. The ability to discriminate was quantified by utilising an area under receiver operating characteristic (AuROC) curve. RESULTS: Two hundred and fifty IHCAs were compared with 1000 controls. Five predictors emerged that were: higher National Early Warning Score (NEWS) at triage, equal or increase of NEWS after ED management, coronary artery disease as a comorbid disease, the use of a vasoactive agent, and initial serum bicarbonate level lower than 23.5 mmoL/L, independently associated with IHCA. The AuROC of the final model from all predictors was 0.91 (95% CI 0.89-0.93) higher than NEWS alone model (AuROC at 0.78, 95% CI 0.74-0.81). CONCLUSIONS: We conclude that a combination of NEWS and four independent predictors identify patients at risk of IHCA more effectively than NEWS alone.

Characteristics and outcomes of treatment in status asthmaticus patients at emergency department.

INTRODUCTION: The characteristics and treatment outcomes of status asthmaticus patients in emergency department (ED) have not been described previously especially in Thailand. OBJECTIVE: To describe the characteristics, treatment outcomes and factors associated with status asthmaticus in Thai patients presenting to a single center ED. METHODS: A prospective observational study was performed at Thammasat University hospital, Thailand. The data collected included demographics, asthma history and control, previous ED attendances and hospital admissions, presenting clinical, laboratory and radiographic features, treatments given, and outcomes. Multivariable regression was used to determine independent factors associated with status asthmaticus. RESULTS: Over one year (2015-16), 209 patients were recruited, aged 6 - 54 years (median 33 y), of whom 145 (69.3%) had status asthmaticus. The factors associated with status asthmaticus were: (i) age > 60 y, (ii) presence of a comorbidity, (iii) having uncontrolled asthma, (iv) hospitalizations or visits to the ED in the last year, and (v) using > 1 metered dose inhaler canister per month. Status asthmaticus patients were significantly less likely to speak in sentences (p=0.001) and more likely to have poor air entry and chest wall retraction (p<0.0001), an abnormal chest X ray (p=0.011), receive magnesium sulphate and be admitted into hospital (p<0.0001). No patients died. CONCLUSIONS: Status asthmaticus was common in this cohort of patients in our setting. Our findings are consistent with previous studies and underscore the need for better patient management.

Study of basic-life-support training for college students.

OBJECTIVE: To study about attitude and knowledge regarding basic-life-support among college students outside medical system. MATERIAL AND METHOD: The cross-sectional study in the emergency department of Thammasat Hospital. The authors included college students at least aged 18 years old and volunteers to be study subjects. The authors collected data about attitudes and knowledge in performing basic-life-support by using set of questionnaires. RESULTS: 250 college students participated in the two hours trainingprogram. Most ofparticipants (42.4%) were second-year college students, of which 50 of 250 participants (20%) had trained in basic-life-support program. Twenty-seven of 250 participants (10.8%) had experience in basic-life-support outside the hospital. Most of participants had good attitude for doing basic-life-support. Participants had a significant improved score following training (mean score 8.66 and 12.34, respectively, p<0.001). Thirty-three of 250 participants (13.2%) passed the minimum score before trained testing, whereas 170 of 250 participants (68%) passed the minimum score after trained testing. CONCLUSION: With accurate knowledge and experience, lay rescuers may have more confidence tope7form basic-life-support to cardiac arrest patient. The training program in basic-life-support has significant impact on knowledge after training.

Acute poison exposure in the emergency department: a 2-year study in a university hospital.

BACKGROUND: Pattern of acute poison exposure varies in the different areas. The information will be useful for prevention. OBJECTIVE: To evaluate pattern, severity and clinical outcome of acute poison exposure in the Emergency Department of a University Hospital in Thailand. MATERIAL AND METHOD: Medical records of all acute poison exposure cases, presented the Emergency Department of Thammasat University Hospital between October 1, 2006 and September 30, 2008 were reviewed retrospectively. Demographic characteristics, exposure time, agents, route and cause of exposure, clinical course and outcome were analyzed. RESULTS: Of the total 76,805 Emergency Department visits, 1112 cases were related to acute poison exposures, which were accounted for 1.4%. Sixty-five percents were female. Patients whom their ages ranging from 21 to 40 years old showed the highest rate of acute poison exposures. Intentional and unintentional exposures accounted for 52.7% and 44.9%, respectively. Intentional exposure was the major cause of exposure in the age group of 11-40 years, while unintentional exposure was the major cause of exposure in children. Pharmaceutical products (38.1%) were the most common category of substances involved in acute poison exposure followed by bites and stings (31.7%) and household products (17.6%). The substances most frequently involved were acetaminophen (17.7%) and toilet cleaning agents (12.3%). Fifty-six (5%) cases developed severe clinical course and three (0.27%) patients died. Pesticide and toilet cleaning agents were responsible for all these fatalities. CONCLUSION: Acetaminophen and toilet cleaning agents were commonly involved in acute poison exposure. Pesticide and toilet cleaning agents caused severe morbidity and mortality. Unintentional exposure was the major cause of exposure in children. Public education regarding the danger of these agents and prevention of the poison exposure in children should be emphasized.
