RESUMO
Objective@#Pesticide poisoning is one of the leading causes of death, and it is important to classify high-risk patients. Lactate measurement could be used to assess the triage level and decide and prioritize treatment even within the same triage group. This study investigates whether point-of-care lactate measurement helps to triage pesticide poisoning patients in the emergency department (ED). @*Methods@#This retrospective study was done for pesticide poisoning patients between January 2018 to December 2021. Demographic data and laboratory results were collected by reviewing medical records. Statistical analysis was performed by dividing patients into death and survival groups. Univariable and multivariable logistic regression analyses were done. Receiver operating characteristic curves were obtained for variables with significant differences, and area under the curves (AUC) were calculated and compared. @*Results@#Among the 288 patients evaluated, there were 24 (8.33%) mortalities and 264 (91.67%) survivals during hospitalization. Age, the Acute Physiology and Chronic Health Evaluation II (APACHE-II) score, pH and base excess, and lactate levels were analyzed via univariable and multivariable logistic regression tests. We found that old age and high lactate were independent factors in predicting mortality for pesticide poisoning patients. AUCs with 95% confidence interval for age and lactate were 0.784 (0.653-0.915) and 0.803 (0.674-0.932), respectively. @*Conclusion@#Lactate measurement may be useful during triage of alert and consciousness patients presenting with pesticide poisoning and having stable vital signs in ED. This study has several limitations, and it is necessary to reconfirm the results through a well-designed prospective study.
RESUMO
Objective@#After the coronavirus disease 2019 (COVID-19) outbreak, there have been some changes in the way the medical system deals with suspected infectious diseases. These changes may also affect non-COVID-19 patients. Acute appendicitis is a common disease that requires emergent surgical intervention in pediatric patients, and delayed diagnosis and treatment may cause some complications. This study analyzed the impact of the COVID-19 pandemic on the incidence of complicated appendicitis in pediatric patients presenting to emergency departments in South Korea. @*Methods@#The target group (post-COVID group) included patients aged under 15 years and diagnosed with acute appendicitis between February 23 and November 30, 2020. Patients diagnosed during the same period in 2019 were selected as the control group (pre-COVID group). The difference in the incidence of complicated appendicitis before and after the COVID-19 outbreak was investigated, and the association with various variables was analyzed using the odds ratios and 95% confidence intervals. @*Results@#The study enrolled a total of 94 patients: 54 in the pre-COVID group and 40 in the post-COVID group. There was no statistically significant variation in the incidence of complicated appendicitis (31.5% vs 35.0%, P=0.723) between the groups. In-hospital time was longer in the post-COVID group (7 hours vs. 10.5 hours, P=0.014), but pre-hospital time showed no significant difference (16 hours vs. 22 hours, P=0.768). In the multivariable logistic regression analysis, pre-hospital time (odds ratio [OR], 1.08; P=0.004), erythrocyte sedimentation rate (OR, 33.24; P<0.001), and the presence of fever (OR, 21.11, P=0.002) showed a significant correlation. @*Conclusion@#Post the COVID-19 pandemic outbreak, there was no difference in the incidence of pediatric complicated appendicitis in South Korea.
