Changing trends in the profile of rodenticide poisoning.

Background: Deliberate self-poisoning (DSP) is one of the leading causes of mortality and morbidity, with rodenticides being common compounds used by many victims. However, comprehensive data regarding the spectrum and outcome of rodenticide poisoning is scant. Method: This retrospective study was conducted in the Emergency Department (ED) of a large tertiary care hospital in South India between January 2017 and December 2018. All patients with deliberate consumption of rodenticides were included in the analysis. Results: During the study period, 1802 patients presented with DSP, among which 145 (8%) consumed rodenticide compounds. The mean (SD) age was 27.9 (10.7) years. Young adults (16-30 years) comprised 73% (106/145) of the study population. The majority (87%) were triaged as priority 2, while 10% were triaged as priority 1. Common rodenticide compounds consumed were yellow phosphorous (57%: 82/145), coumarins (12%: 17/145), zinc phosphide (19%: 27/145), and aluminum phosphide (1%: 1/145). A significant proportion of patients (18.6%) were under the influence of alcohol. Among the 73 males, 25 (34.2%) gave a history of co-consumption of alcohol. There was a history of previous DSP attempts in 6%. The majority (68%) of the patients were discharged alive from the hospital, and the in-hospital mortality rate was 9%. Age >30 years (adjusted OR: 2.2; 95% CI: 1.00-5.05; p value: 0.04) was an independent predictor of poor outcome. Conclusion: Rodenticide compound consumption for DSP is prevalent in young adults and is associated with significant mortality, especially with yellow phosphorous poisoning. The current trend in our country of the increasing use of highly fatal phosphorous compounds over the innocuous coumarin derivatives is a cause of grave concern.

Deliberate self-poisoning and harm: A meticulous quest of methods in vogue.

Background: Deliberate self-poisoning and harm (DSPH) is an unabating problem with a wide variation in the methods used across the world. Hence, this study was conducted to understand the current spectrum of methods used for DSPH by patients in our geographic locality and catchment area with special emphasis on newer compounds and drugs used. Methods: This retrospective study included patients presenting with DSPH to the emergency department (ED) between January 2017 and December 2018. Results: This study included 1802 patients, with a mean age of 32 ± 12.7 years. Of the patients, 85% were in the young to middle age group (16-45 years). Agrochemicals (n = 604, 33.5%), drugs (n = 498, 27.6%), plant toxins (n = 150, 8.3%) and rodenticides (n = 145, 8%) were the predominantly used compounds. The major emergency resuscitation procedures required in the ED were intubation (n = 321, 18%), vasopressor support (n = 73, 4%) and cardiopulmonary resuscitation (n = 27, 1.4%). A quarter (23.2%) was discharged stable from the ED, whereas a further 56.5% were discharged stable after hospital admission. The in-hospital mortality rate was 3% (n = 47). Multivariate logistic regression analysis showed rodenticides (odds ratio (OR): 22.32; 95% confidence interval (CI): 8.05-61.88; P = 0.005) and plant poisons (OR: 23.92; 95% CI: 8.95-63.94; P = 0.005) to be the independent predictors of mortality. Conclusion: DSPH is prevalent in the highly productive young age group. Agrochemical ingestion and drug overdose are the most common methods used, whereas rodenticide and plant poisoning are associated with significant mortality.

Deliberate Self-poisoning due to Plant Toxins: Verdant Footprints of the Past into the Present.

BACKGROUND: Plant poisoning is one of the common methods of deliberate self-poisoning (DSP). Exposure to plants and its consequence account for a considerable number of deaths in rural India. MATERIALS AND METHODS: This retrospective observational study was conducted in the emergency department of a large tertiary care hospital in South India over a period of 2 years and recruited patients who presented with DSP from plant poisoning. RESULTS: During the study period, 150 cases of plant poisoning were included. The mean (standard deviation) age of presentation was 31.4 (12.2) years. The most common type of plant poison consumed was oleander (63%) followed by oduvanthalai (50%), Strychnos nux-vomica (3%), datura (3%), and others, which comprised about 5.3% included henna (1.3%), cactus (1.3%), and a case each of castor, Gloriosa superba, Adenanthera pavonina, and Abrus precatorius. Patients in age-group 16-30 years had the highest rate of ingestion. The seasonal pattern was found to peak in the month of April. Gastric lavage was done in 102/150:68%. Consumption of decoction [odds ratio (OR): 5, 95% confidence interval (CI): 2.27-14.00, p value: <0.001] and metabolic acidosis (pH <7.35) (OR: 11.48, 95% CI: 4.17-31.57, p value: <0.001) were more common in oduvanthalai poisoning as compared to oleander. The mortality among plant poisoning was 9.3% (14/150). CONCLUSION: Our study sheds light on the spectrum of local plants consumed for DSP. Oleander and oduvanthalai were most commonly used for DSP. Consuming a decoction of leaves leading to severe metabolic acidosis at presentation is seen associated with oduvanthalai poisoning.

Prevalence, Spectrum, and Outcome of Deliberate Self-harm Presenting to Emergency Department during COVID-19 Pandemic of 2020.

BACKGROUND: The coronavirus disease-2019 (COVID-19) pandemic, and the lockdown imposed, has had profound social and economic consequences and thereby implications on psychological health. This study aims to understand the effects of the pandemic and the lockdown on the prevalence, spectrum, and outcome of patients presenting with deliberate self-harm (DSH) to the emergency department (ED). MATERIALS AND METHODS: This was a retrospective, observational study done in the ED of a tertiary care hospital in South India on DSH victims presenting from January to August 2020, spanning the prelockdown, lockdown, and unlock phases of the pandemic, and compared with data from a similar period in 2018. RESULTS: Our study population included 507 DSH victims (prevalence: 1.2%) from January to August 2020. The percentage of DSH cases showed a slight increase among the prelockdown (203/17,234: 1.18%), the lockdown (179/14,687: 1.22%), and the unlock phases (125/9,977: 1.25%). There was a female preponderance (286/507: 56.4%), and the mean age was 33.2 years. Of the 507 patients, 369 (72.8%) were admitted and 19 (3.7%) died. The lockdown period in 2020 showed a 40.9% absolute decrease in the number of DSH victims presenting to the ED as compared to an equivalent period in 2018. The proportion of patients taking plant poisons was significantly lower [odds ratio (OR) 0.38, 95% confidence intervals (CI) 0.18-0.81, p = 0.012] and that of corrosive ingestion was significantly higher (OR 2.94, 95% CI 1.57-5.48, p = 0.001) in the lockdown phase as compared to a lockdown-control phase of 2018. CONCLUSION: There was a reduction in the absolute number of patients presenting with DSH to the ED during January-August 2020, and more so during the lockdown phase (March 24-June 30), as compared to a similar period in 2018. There was no significant difference in the hospital outcome of DSH patients between the two periods. HOW TO CITE THIS ARTICLE: John SM, John A, Hazra D, Murugan S, Abhilash KPP.

Airway status at arrival to the Emergency department among patients with life threatening emergencies.

BACKGROUND: Despite the improvement in prehospital care in the last decade in India through dedicated ambulance services, airway management is often performed by undertrained or untrained personnel and remains teetering to the edge of collapse. This study aimed at assessing the airway status in critically ill patients at their arrival to the Emergency Department (ED). METHODS: This prospective study included all triage priority I patients presenting to the ED during August 2017 and September 2017. Details of their airway status at arrival to the ED was noted. The severity at presentation and outcome of patients brought in ambulances and private vehicles were determined using descriptive analytic statistics and bivariate logistic regression analysis. RESULTS: The study included 450 patients, with a male predominance (65.3%). Only a third (31%) of patients were brought in ambulances with a reminder through various means of transport. Compared to patients brought by private vehicles, patients brought to the ED by ambulances had a higher odds of being hypoxic at ED arrival [OR: 1.63 (95% CI: 1.08-2.46); P value: 0.01] and requiring invasive ventilation on arrival to the ED [OR: 2.36 (95% CI: 1.46-3.80) P value: < 0.001]. Overall, 55.7% (248/450) required hospital admission while 21% (95/450) were discharged stable from the ED after resuscitation and stabilization by the ED team. The overall mortality rate was 11.1% (50/450), with 13.5% (19/144) of those brought by ambulances and 10% (31/309) of those brought by private vehicles succumbing to their illness in the hospital. CONCLUSION: Private vehicles still remain the predominant mode of prehospital transport though ambulances are used to transport sicker patients. More than half the critically ill patients remained hypoxic on arrival to the ED. Our study clearly highlights the glaring deficiency in airway status at ED arrival and stresses the urgent need to improve prehospital care.
