Objective: The objective of the study is to test the efficacy of high-dose methylprednisolone in the prevention of esophageal stricture after corrosive ingestion.

Methods: This study was a single-center, randomized controlled single-blinded study. Simple randomization was done with 15 adult patients (>18 years) in each arm, who presented with a history of corrosive ingestion within the past 24 h and had esophageal injury of Zargar Grade IIB on endoscopy.

Assessment of Troponin I Levels as a Predictor of Mortality in Acute Decompensated Heart Failure.

Background: Acute decompensated heart failure (ADHF) is a highly prevalent diagnosis in the emergency department and is associated with high morbidity and mortality. As mortality remains high even in patients discharged from the emergency, it becomes mandatory to identify markers predictive of mortality in order to guide the disposition of such patients. No literature is available on the prognostic significance of Troponin I in ADHF patients in an emergency setting from an Indian standpoint.

High-dose versus low-dose intravenous nitroglycerine for sympathetic crashing acute pulmonary edema: a randomised controlled trial.

Objectives: Sympathetic crashing acute pulmonary edema (SCAPE) is a subset of heart failure with a dramatic presentation. The unique physiology of this condition requires a different management strategy from the conventional practice. The trial objective was to compare the efficacy of high-dose and low-dose GTN in patients with SCAPE.

Diagnostic accuracy of drooling, reluctance, oropharynx, others, and leukocytosis score as a predictor of mortality and complications following acute corrosive ingestion.

Objectives: Esophagogastroduodenoscopy is considered the gold standard in assessing the severity of injury to the gastrointestinal tract following corrosive ingestion. Zargar's endoscopic grading of injury helps in prognostication as well as guiding management. Since the major burden of cases lies in resource-limited settings, the availability of endoscopic evaluation is a limiting factor.

Emergency Department Point-of-Care Tests during Cardiopulmonary Resuscitation to Predict Cardiac Arrest Outcomes.

Introduction: This study evaluated the role of point-of-care tests (POCT) such as blood lactate, anion gap (AG), base deficit, pH, N-terminal pro B-type natriuretic peptide (NT-proBNP), and troponin as the predictors of cardiac arrest outcomes in the emergency department (ED).

Methods: We conducted a prospective, observational study in the ED of a tertiary care hospital in India. All the adult patients who received cardiopulmonary resuscitation (CPR) in the ED were included in the study.

Phylogeny and evolution of SARS-CoV-2 during Delta and Omicron variant waves in India.

SARS-CoV-2 evolution has continued to generate variants, responsible for new pandemic waves locally and globally. Varying disease presentation and severity has been ascribed to inherent variant characteristics and vaccine immunity. This study analyzed genomic data from 305 whole genome sequences from SARS-CoV-2 patients before and through the third wave in India.

Performance of qSOFA Score as a Screening Tool for Sepsis in the Emergency Department.

Introduction: Sepsis is the leading cause of mortality, and various scoring systems have been developed for its early identification and treatment. The objective was to test the ability of quick sequential organ failure assessment (qSOFA) score to identify sepsis and predict sepsis-related mortality in the emergency department (ED).

Methods: We conducted a prospective study from July 2018 to April 2020.

The Role of Triple Rule-out CT in an Indian Emergency Setting.

Background: Emergency physicians are acutely aware of the consequences of missing fatal diagnoses for acute non-traumatic chest pain and subjecting patients to over-testing. In the large arsenal of tests that are available to us, a triple rule-out computed tomography (TRO-CT) Angiography is often less pursued, due to concerns about their efficacy and safety or because of nescience. We aim to find the yield of the test in an Indian emergency setting and impart some knowledge about it along the way.

Learning to switch gears - Steering palliative care into emergency medicine.

Emergency care is largely seen as synonymous with resuscitation and saving lives. In most of the developing world where Emergency Medicine (EM) is still evolving, the concept of EM palliative care is alien. Provision of palliative care in such settings poses its own challenges in terms of knowledge gaps, socio-cultural barriers, dismal doctor-to-patient ratio with limited time for communication with patients, and lack of established pathways to provide EM palliative care.

Nebulized vs IV Tranexamic Acid for Hemoptysis: A Pilot Randomized Controlled Trial.

Background: Tranexamic acid (TA) is used to control bleeding in patients with hemoptysis. However, the effectiveness of the different routes of TA administration has not been studied.

Research Question: Does the nebulized route of TA administration reduce the amount of hemoptysis compared with the IV route in patients presenting to the ED with hemoptysis?

Study Design And Methods: This was a pragmatic, open-label, randomized, parallel, single-center, pilot trial of nebulized TA (500 mg tid) vs IV TA (500 mg tid) in adult patients presenting to the ED with active hemoptysis.

Prospective Validation of a Novel Triage System Developed in a Middle Income Country - AIIMS Triage Protocol.

Introduction: Triage is a crucial process not only to identify sick patients and prioritize prompt management but also to foster efficient resource utilization. In low-and middle-income countries (LMICs) most emergency departments (ED) still have an informal triage process. Although an important element of emergency care, triage research has not been a priority in LMICs, and hence, very few triage systems have been validated.

Airway management practices among emergency physicians: An observational study.

Objectives: Emergency airway management is an integral part of patient stabilization. It is an essential skill for an emergency physician to master. There is a paucity of literature on airway management from low-to-middle-income countries like India where emergency medicine (EM) specialty is still in its infancy.
