Diagnostic Accuracy of Ocular Ultrasonography in Identifying Raised Intracranial Pressure among Pediatric Population.

INTRODUCTION: Role of CT scan, MRI, ophthalmoscopy, direct monitoring by a transducer probe in identifying raised intracranial pressure (ICP) in emergency department is limited. There are few studies correlating elevated optic nerve sheath diameter (ONSD) measured by point of care ultrasound (POCUS) with raised ICP in pediatrics emergencies. We studied the diagnostic accuracy of ONSD, crescent sign, and optic disc elevation in identifying increased ICP in pediatrics. METHODS: Prospective observational study was done between April 2018 and August 2019 after ethics approval. Out of 125 subjects, 40 patients without clinical features of raised ICP were recruited as external controls and 85 with clinical features of raised ICP as study subjects. Their demographic profile, clinical examination, and ocular ultrasound findings were noted. This was followed by CT scan. Out of 85 patients, 43 had raised ICP (cases) and 42 had normal ICP (disease controls). Diagnostic accuracy of ONSD in identifying raised ICP was evaluated using STATA. RESULTS: The mean ONSD in case group was 5.5 ± 0.6 mm, 4.9 ± 0.5 mm in disease control group and external control group was 4.8 ± 0.3 mm. Cut-off of ONSD for raised ICP at ≥4.5 mm had a sensitivity and specificity of 97.67% and 10.98%, while ≥5.0 mm showed a sensitivity and specificity of 86.05% and 71.95%. Crescent sign and optic disc elevation had good correlation with increased ICP. CONCLUSION: ONSD ≥5 mm by POCUS identified raised ICP in pediatric population. Crescent sign and optic disc elevation may function as additional POCUS signs in identifying raised ICP.

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. The primary outcome was cessation of bleeding at 30 min. Secondary outcomes included amount of hemoptysis at 6, 12, and 24 h; interventional procedures; and side effects of TA. Patients who were hemodynamically unstable or requiring immediate interventional procedure or mechanical ventilation were excluded from the study. RESULTS: Of the 55 patients in each arm, hemoptysis cessation at 30 min following TA administration was significantly higher in the nebulization arm (n = 40) compared with the IV arm (n = 28): χ2 (1, n = 110) = 5.55; P = .0019. Also, hemoptysis amount was reduced significantly in the nebulization arm at all time periods of observation (P value at 30 min = .011, at 6 h = .002, 12 h = .0008, and at 24 h = .005). Fewer patients in the nebulization arm required bronchial artery embolization (13 vs 21; P = .024) and thereby had higher discharge rates from the ED (67.92% vs 39.02%; P = .005). Two patients in the nebulization arm had asymptomatic bronchoconstriction that resolved after short-acting beta-agonist nebulization. No patient discharged from the ED underwent any interventional procedure or revisited the ED with rebleed during the 72 h follow-up period. INTERPRETATION: Nebulized TA may be more efficacious than IV TA in reducing the amount of hemoptysis and need for ED interventional procedures. Future larger studies are needed to further explore the potential of nebulized TA compared with IV TA in patients with mild hemoptysis.

Strengthening emergency care systems to improve patient care for ST-elevation myocardial infarction (STEMI) at a high-volume tertiary care centre in India.

BACKGROUND: ST-elevation myocardial infarction (STEMI) is a highly time-sensitive and life-threatening condition. Early recognition and timely management are challenging in a busy emergency department (ED), especially in low/middle-income countries where emergency systems are often fragmented. The aim of our quality improvement (QI) project was to increase the percentage of patients with STEMI undergoing primary percutaneous coronary intervention (PCI) with door to balloon (D2B) time of <90 min by 30% over 12 months. METHODS: As part of the first step in QI, baseline data were collected at different points in the process of care. Using process maps and fishbone analysis, delays in patient registration, ECG and communication with cardiology were identified as some bottlenecks, and change ideas were tested using plan-do-study-act cycles using point-of-care QI methodology. The majority of the change ideas focused on interventions in the ED like strengthening triage, training frontline staff, early diagnosis and quick transportation of patients. RESULTS: During the baseline phase, 22.22% of patients were found to have a D2B time of <90 min. We achieved an increase of 47.78% in patients receiving PCI within 90 min and hence increased to 70% at the end of the intervention phase. Data collected for 4 months after the intervention phase were found to have sustained the effort. CONCLUSION: Significant improvement in the door to reperfusion time resulted from a meticulous assessment of emergency care processes by drawing process flow chart and implementation of change ideas like introduction of fast-track policy for patients with chest pain, reducing staff turnover in the triage area, formal training of staff, continuous engagement with cardiology team and by interchanging of processes which led to a reduction in time to ECG.

Acute lead poisoning: a diagnostic challenge in the emergency department.

Acute abdominal pain is a common presentation to the emergency department (ED). Ruling out life-threatening causes and giving pain relief are the most important tasks in ED. We describe a 32-year-old man who presented to ED with abdominal pain and vomiting which was unrelieved by usual doses of analgesic. Extensive investigations revealed no significant abnormalities. On further probing, he admitted taking traditional medications for infertility. The toxicological panel revealed a high blood lead level, leading to a diagnosis of acute lead toxicity. Chelation therapy with D-penicillamine was initiated and the patient's abdominal pain resolved within 4 days.

Development and Validation of a Questionnaire to Evaluate Workplace Violence in Healthcare Settings.

Introduction This study aims to develop and validate a questionnaire to assess workplace violence (WPV) domains in the healthcare setting. Methods  The study used a mixed-method design. In Phase 1, qualitative methods for developing the questionnaire were employed, including literature review, focus-group discussion, expert evaluation, and pre-testing. During Phase 2, quantitative methods were employed for establishing the construct validity of the questionnaire. In Phase 1, experts from departments like emergency medicine, medicine, obstetrics and gynecology, psychiatry, trauma, anesthesia, and critical care unit participated. For Phase 2, data were collected from 213 participants; mean age (30.48±5.95) in metropolitan cities. Results The questionnaire consists of 37 items in five domains: (A) Forms of violence, (B) Impact of violent incidences, (C) Reporting of incidence, (D) Mitigation strategies, and (E) Risk factors. The Cronbach's alpha value of the questionnaire is 0.86, suggesting an excellent internal consistency. Conclusion A reliable and valid tool for gathering information regarding WPV in the healthcare system from around the world has been developed. The tool can be used to study the elements that may contribute to violence and its consequences, which will help policymakers curate various mitigation methods to safeguard WPV victims.

Mobile phone ingestion requiring endoscopic retrieval.

A 24-year-old male was brought to our emergency with complaints of abdominal pain for two days. There was a history of foreign body ingestion five days earlier, details of which he refused to reveal. After investigation with abdominal X ray and ultrasound, the foreign body was detected to be a mobile phone containing a battery. Clinical evaluation revealed no signs of lithium toxicity due to battery leak. The patient underwent endoscopy for removal of the mobile phone. The case shows the importance of thorough investigation and prompt attempt at endoscopic removal in the event of ingestion of foreign bodies containing batteries.
