Does apneic oxygenation with nasopharyngeal cannula during intubation improve the oxygenation in patients with acute hypoxemic respiratory failure compared to the standard bag valve mask preoxygenation? An open-labeled randomized control trial.

OBJECTIVES: In the context of acute hypoxemic respiratory failure (AHRF), ensuring effective preoxygenation and apneic oxygenation emerges as the pivotal approach ensuring for averting hypoxemic adverse events during endotracheal intubation. To investigate this, we conducted an open-label randomized controlled trial, aiming to assess the comparative effectiveness of nasopharyngeal high-flow oxygenation in conjunction with Bag-Valve-Mask (BVM) versus standard BVM preoxygenation in patients experiencing AHRF within the emergency department (ED). METHODS: This prospective single-center, open-labeled, randomized controlled trial enrolled patients aged 18 years and above requiring rapid sequence intubation due to AHRF in the ED. Participants were randomly assigned in a 1:1 ratio to either the intervention arm (involving nasopharyngeal high-flow oxygenation and BVM preoxygenation) or the control arm (involving BVM preoxygenation alone). RESULTS: A total of 76 participants were enrolled in the study, evenly distributed with 38 individuals in each arm. Median (interquartile range [IQR]) SpO2 at 0 min postintubation was 95.5 (80%-99%) versus 89 (76%-98%); z-score: 1.081, P = 0.279 in the intervention and control arm, respectively. The most common postintubation complications included hypoxia (intervention arm: 56.7% vs. control arm: 66.7%) and circulatory/hypoxic arrest (intervention arm: 39.5% vs. control arm: 44.7%). There were no adverse complications in 36.7% (n = 11) of patients in the intervention arm. Despite the best possible medical management, almost half (52.6%) of patients in the intervention arm and 47.4% of patients in the control arm succumbed to their illnesses in the ED. CONCLUSION: The primary outcome revealed no statistically significant difference between the two arms. However, patients in the intervention arm exhibited fewer intubation-related adverse effects.

Prognostication and Prediction of Outcomes in Patients with Organophosphorus and Carbamate Poisoning: A Prospective Cohort Study.

Background: Organophosphorus (OP) and carbamate poisoning are significant concerns in developing nations. This study evaluates the effectiveness of the ChE check mobile, a cholinesterase-rapid bedside diagnostic test, in the diagnosis and management of OP and carbamate poisoning. Materials and methods: We conducted this prospective observational study, involving patients with OP and carbamate poisoning over 1 year (June 2016 to June 2017) at a single tertiary care center. Levels of RBC cholinesterase (E-AChE), butyl cholinesterase (BChE), and various other determinants were systematically coded and analyzed. Results: The study population (n = 60) consisted primarily of males (n = 43; 71.7%), with a mean age of 30.6 (SD: 13.7) years. Monocrotophos (n = 10; 20.4%) and carbofuran (n = 4; 8.1%) were the commonest OP and carbamate compounds, respectively. The median initial atropinization dose was 10 (IQR: 0, 61.5) mg, with a median total administered atropine dose of 116 (IQR: 32, 320) mg. A significant negative correlation was found between E-AChE levels and both the initial atropinization dose (ρ: -0.653, p-value < 0.001) and total atropine requirement (ρ: -0.659, p-value < 0.001) during admission. An E-AChE cut-off of 4 units/g hemoglobin provided an area under the curve of 0.73 (sensitivity: 80.0%, specificity: 68.6%, p-value < 0.001) for predicting moderate to severe peradeniya organophosphorus poisoning. Conclusion: The check mobile device can be a valuable tool for prognosticating patients. There was a significant correlation between low E-AChE levels and the atropine requirement and severity.

Unveiling the Crystal Ball: Predictors of Adverse Outcomes in Intracerebral Hemorrhage Patients.

Introduction: Intracerebral hemorrhage (ICH) is a severe form of stroke with substantial morbidity and mortality worldwide. Despite its impact, research has often focused on ischemic strokes, making ICH an essential area to explore. Methods: A retrospective cohort study spanning 5 years was conducted in an Oman-based tertiary care teaching hospital's emergency room. Data from patients diagnosed with spontaneous ICH, confirmed by cranial CT scans, were analyzed. Ethical approval was obtained. Results: Among 163 emergency room (ER)-presented patients with ICH, 89 met the inclusion criteria. Most were male (69.66%), with hypertension (69/89) and diabetes mellitus (43/89) being common comorbidities. Hematoma size was a crucial predictor of poor outcomes, especially for larger hematomas (>60 cm³). Midline shift, intraventricular hemorrhages, elevated systolic and diastolic blood pressure, and low Glasgow Coma Scale (GCS) scores were significantly associated with unfavorable outcomes. However, variables such as age, gender, history of heart disease, hypertension, diabetes, and anticoagulant use did not show significant associations with disability outcomes. Favorable outcomes (mRS <3) were observed in 47.2% of patients, while 30.3% had a major disability (mRS 3-5), and 22.5% succumbed to their illness (mRS 6). Conclusion: This study enhances our understanding of ICH outcomes, highlighting the importance of hematoma size, midline shift, intraventricular hemorrhage, blood pressure control, and GCS scores in predicting disability. Future research could explore additional prognostic factors and interventions for ICH patients. How to cite this article: Al-Alawi AKA, Hazra D, Al-Hassani MJK, Al-Jamoudi ASA.

Subthalamic Deep Brain Stimulation in Parkinson's Disease: A Boon or Bane - A Single Centre Retrospective Observational Study from India.

Background Subthalamic deep brain stimulation (STN-DBS) for refractory Parkinson's disease (PD) is more of a modality of treatment that is empirical, for which a physiological explanation is being sought. This study was done to determine the outcome and complications of patients undergoing STN-DBS for PD. Methods This retrospective observational cohort study was conducted in an advanced neuromedicine facility in eastern India for 9 years (August 2013-August 2022), which included all patients undergoing STN-DBS. Results A total of 53 patients were operated on during the study period. The mean age group of the study population was 60.5 (standard deviation [SD]: 8.2) years with a male (33 [62.3%]) predominance. The most common presenting complaints included rigidity and hypokinesia (27), severe dyskinesia (21), and tremors (17). During the postoperative period, rigidity and hypokinesia (21), severe dyskinesia (16), and tremors (12) improved significantly in a subset of the patients. The majority (45 [84.9%]) of these cases received bilateral monopolar simulation, whereas three patients (5.7%) had bilateral bipolar stimulation. Unilateral bipolar stimulation was used in five (9.4%) patients. In the immediate postoperative period, they were initiated on limb, speech, and swallowing therapy as indicated. Surgery-related complications were seen in five (9.4%) cases. At 6 months of follow-up, a significant improvement in the Unified PD rating scale component (mainly motor examination and complication of PD therapy) was noted in the majority (36 [67.9%]) of patients. One patient developed neuroleptic malignant syndrome and succumbed to his illness on the fourth postoperative day. Conclusion Given these findings, STN-DBS appears to be a good, safe, and effective treatment for a subset of medically refractory PD with an overall improvement in two-thirds of the study cohort and less than 10% risk of complications.

Impact of Fatigue on Emergency Physicians' Decision-making for Computed Tomographic Scan Requests and Inpatient Referrals: An Observational Study from a Tertiary Care Medical Center of the Sultanate of Oman.

Objective: Multiple factors contribute to decision fatigue experienced by emergency physicians (EPs). This study examines the association between decision fatigue and the frequency of computed tomographic (CT) scan requests and inpatient referrals among EPs. Methods: This retrospective database analysis was done for 3 months. Scans and inpatient referral requests were coded and analyzed to assess the impact of physician fatigue on decision-making. Subsequently, the outcomes were evaluated. Results: The majority of patients (n = 481; 51.1%) had a CT brain request. Among these requests, the morning shift (8:00 a.m.-3:00 p.m.) accounted for the highest number (n = 400; 42.5%), followed by the evening shift (3:00-11:00 p.m.) (n = 345; 36.7%). Approximately one-third of the patients (n = 301; 31.9%) had positive CT scan findings. Statistical analysis comparing the first and the second halves of each shift did not reveal significant variations in the percentage of negative CT results (p-value: 0.093). Inpatient referral was necessary for over half of the patients (n = 1,048; 52.7%), and the majority of these referrals (n = 778; 74.2%) were deemed necessary for treatment under various surgical or medical specialties. There was a statistically significant difference in the proportion of negative inpatient referrals between the first and the second halves of the afternoon shift (p-value < 0.001). Conclusions: Fatigue among EPs was observed, leading to more frequent consultations without inpatient admission during the latter half of the afternoon shift. However, the study found no significant impact of decision fatigue on CT scan decision-making. How to cite this article: Al-Arimi AH, Hazra D, Al-Alawi AKA.

A clinico-epidemiological profile, coinfections and outcome of patients with Influenza Like Illnesses (ILI) presenting to the emergency department during the COVID-19 pandemic.

Background: During the COVID-19 pandemic, many patients presented to the emergency department (ED) with features of Influenza-like illnesses (ILI) and with other atypical presentations. This study was done to determine the etiology, co-infections, and clinical profile of patients with ILI. Methods: This prospective observational study included all patients presenting to the ED with fever and/or cough, breathing difficulty, sore throat, myalgia, gastrointestinal complaints (abdominal pain/vomiting/diarrhea), loss of taste and altered sensorium or asymptomatic patients who resided in or travelled from containment zones, or those who had contact with COVID-19 positive patients during the first wave of the pandemic between April and August 2020. Respiratory virus screening was done on a subset of COVID-19 patients to determine co-infection. Results: During the study period, we recruited 1462 patients with ILI and 857 patients with the non-ILI presentation of confirmed COVID-19 infection. The mean age group of our patient population was 51.4 (SD: 14.9) years with a male predominance (n-1593; 68.7%). The average duration of symptoms was 4.1 (SD: 2.9) days. A sub-analysis to determine an alternate viral etiology was done in 293 (16.4%) ILI patients, where 54 (19.4%) patients had COVID 19 and co-infection with other viruses, of which Adenovirus (n-39; 14.0%) was the most common. The most common symptoms in the ILI-COVID-19 positive group (other than fever and/or cough and/or breathing difficulty) were loss of taste (n-385; 26.3%) and diarrhea (n- 123; 8.4%). Respiratory rate (27.5 (SD: 8.1)/minute: p-value < 0.001) and oxygen saturation (92.1% (SD: 11.2) on room air; p-value < 0.001) in the ILI group were statistically significant. Age more than 60 years (adjusted odds ratio (OR): 4.826 (3.348-6.956); p-value: <0.001), sequential organ function assessment score more than or equal to four (adjusted OR: 5.619 (3.526-8.957); p-value: <0.001), and WHO critical severity score (Adjusted OR: 13.812 (9.656-19.756); p-value: <0.001) were independent predictors of mortality. Conclusion: COVID-19 patients were more likely to present with ILI than atypical features. Co-infection with Adenovirus was most common. Age more than 60 years, SOFA score more than or equal to four and WHO critical severity score were independent predictors of mortality.

Performance of Aerosol Boxes for Endotracheal Intubation during the COVID-19 Pandemic with Systematic Review.

Introduction: In the backdrop of the COVID-19 pandemic, endotracheal intubation using an aerosol box (AB) became the norm in the emergency department (ED) and the intensive care unit. We compared two models of AB with different dimensions to compare and identify a device that helps in reducing viral exposure without compromising successful airway management. Methods: We conducted this prospective observational study for 7 months (October 20-April 21) on 143 patients presenting with an acute airway compromise to the ED. All intubations were performed using one of the two models available. The primary outcome was time taken for intubation (TTI). Results: The overall median time taken to intubate using any AB was 63 (interquartile range [IQR]: 46.2-87.7) s with an 81.9% first-pass success (FPS) rate. TTI for AB I was 67 (IQR: 53-106) s with a 76.3% FPS rate, while TTI for AB II was 57 (IQR: 44-75) s with an 85.9% FPS rate. TTI was much shorter without the use of an AB (34: IQR: 24-53 s) with a 92% FPS rate. Intubations done by emergency physicians with more than 2 years of experience were faster in both with or without AB when compared to intubations done by physicians with <2 years of experience. Conclusion: The use of an AB is associated with a longer TTI when compared to intubations done without an AB. TTI was relatively shorter when more experienced emergency physicians performed intubation. FPS rates were low with intubations done using AB.

Prospective review of 188 cases of epistaxis presenting to the emergency department: Etiology and outcome.

Background: Due to a myriad of risk factors, epistaxis is a very frequent presentation to the emergency room (ER). This study aims to ascertain the prevalence of epistaxis in our population, risk factors, effectiveness of ER treatment, complications, and ER outcome. Materials and Methods: This was a prospective observational study performed in the ER of a referral tertiary care center in south India. Data were categorized, coded, and analyzed to determine the objective of the study. Results: During the study's six-month duration, 188 (0.6%) patients presented with epistaxis. The mean age was 42.9 (SD: 16.49) years, with a male preponderance of 143 (76.1%). A majority of these patients (n: 156; 82.9%) were triaged as priority II, with hypertension (n: 53, 28.2%) as the commonest comorbidities. Trauma-related epistaxis (n: 107, 56.9%) was the most frequent cause. Anterior nasal packing was carried out for 85 (45.2%) patients, posterior nasal packing was carried out for one (0.5%) patient, and bleeding had spontaneously resolved in the majority (n: 102; 54.3%) patients. Seven (3.7%; p-value: 0.001) patients had recurrent epistaxis, and of those, three (1.6%) required urgent resuscitation with crystalloid fluid and blood products. Two of these patients had bleeding dyscrasias, four had history of trauma, and one patient presented with uncontrolled hypertension. Two (1.1%) patients came back to us with recurrent bleeding within 12 h of discharge. Majority (69.2%; 130) were discharged stable, (23.9%; 45) were admitted for observation and (6.9%; 13) were discharged against medical advice. There was no mortality among these study populations. Conclusion: Middle-young, aged males most commonly presented with epistaxis. Most of them were secondary to trauma. Anterior nasal bleeding was the most common source and hemostasis could be obtained by anterior nasal packing. Majority could be discharged stable from the ER. However, this cohort had seen patients in life-threatening conditions, so the severity cannot be overlooked.

Surgical Outcome of Basal Ganglia Hemorrhage: A Retrospective Analysis of Nearly 3,000 Cases over 10 Years.

Background Basal ganglia hemorrhage (BGH) is a severe neurologic condition associated with significant morbidity and mortality, and its optimal management remains a topic of debate. Our study assessed the surgical outcomes of BGH patients at the 3-month mark using the modified Rankin Scale (mRS). Methods This retrospective observational study was conducted over 10 years at an advanced neuro-specialty hospital in Eastern India, including patients who underwent decompressive craniotomy and hematoma evacuation. Variables were systematically coded and analyzed to evaluate the postoperative outcome with age (in years), preoperative motor (M) status, and hematoma volume. Results This study enrolled 2,989 patients with a mean age of 59.62 (standard deviation: 9.64) years, predominantly males ( n = 2,427; 81.2%). Hypertension (1,612 cases) and diabetes mellitus (1,202 cases) were the most common comorbidities. Common clinical presentations included ipsilateral weakness (1,920 cases) and/or altered mental status (1,670 cases). At the 3-month mark postsurgery, 2,129 cases (71.2%) had a favorable outcome based on mRS, while 389 cases (13.0%) had an unfavorable outcome. The regression equation showed that age was inversely related to the percentage of individuals achieving a favorable outcome. It also revealed that the preoperative motor score was positively correlated with favorable outcomes. Hematomas smaller than 60 mL had better outcomes, with 1,311 cases (69.1%) classified as good outcomes and 337 cases (17.8%) as bad outcomes. Fatal outcomes related to the illness were observed in 471 patients (15.8%) within the study population. Conclusion Surgery for BGH showed a substantial improvement in outcomes, particularly in patients with M5/M4 motor status. The preoperative motor score (M status) emerged as a crucial predictor of favorable neurological outcomes. Age and hematoma volume, however, were found to be nondefinitive factors in determining good outcomes.

Prevalence of Hypocortisolemia in Patients with Sepsis or Septic Shock (The HIS Study) Presenting to the Emergency Department.

Background: Cortisol response to stressors (hypothalamic-pituitary-adrenal axis, autonomic nervous system, and immune system) plays a vital role in maintaining stable metabolic homeostasis. This study was done to assess the prevalence of hypocortisolemia in patients presenting to ED with sepsis and/or septic shock. Methods: This prospective observational study was done from July 2020 to April 2021. Serum cortisol levels were measured in patients with sepsis and septic shock, and their clinical and laboratory profile was categorized, coded, and analyzed. Results: Ninety-eight patients were included, of which serum Cortisol <10 µg/dl was noted in 7 (7.2%) patients. The cohort's mean age was 52.9 (SD: 15.3) years with a male predominance (n-61; 62.2%). Most common presenting complaint was fever (n-52; 53.1%), followed by abdominal pain (n-24; 24.5%), and breathing difficulty (n-14; 14.3%). Systolic blood pressure <90 mmHg and tachycardia were seen in 63 patients (64.3%). Assessment of diet and native medication use did not demonstrate a predisposition to hypocortisolemia. The median (IQR) arterial lactate values were lower in the hypocortisolemic group: 2.2 (1.2-2.5) as compared to the non-hypocortisolemic group: 3.7 (2.2-8.0). Patients with septic shock without hypocortisolemia were noted to have a higher mean lactate level (2.6 ± 1.3 Vs 5.4 ± 3.9) and lower platelet counts compared to those with low cortisol levels. Patients with normal cortisol levels (n-38; 38.8%) still had low ACTH values. Conclusion: The prevalence of hypocortisolemia was lower when compared to other Indian studies. Diet and native medication use do not predispose Indians to hypocortisolemia.

Retrospective study of comparison of clinical severity and outcome of hospitalised COVID-19 patients during the first and second waves of the pandemic in India.

OBJECTIVES: To compare the clinical severity and outcome of hospitalised patients during the two waves of the COVID-19 pandemic in India. SETTING: A tertiary care referral hospital in South India. PARTICIPANTS: Symptomatic SARS CoV-2 reverse transcriptase PCR positive patients presenting to the emergency department during the two waves were recruited. The first wave spanned between April and December 2020 and the second wave between April and May 2021. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome of interest was mortality. Secondary outcomes included illness severity at presentation, need for oxygen therapy, non-invasive ventilation (NIV) and hospital or intensive care unit admission. RESULTS: The mean (SD) age of the 4971 hospitalised patients in the first wave was similar to the 2293 patients in the second wave (52.5±15.4 vs 52.1±15.1 years, p=0.37). When compared with the first wave, during the second wave, a higher proportion of patients presented with critical illness (11% vs 1.1%, p<0.001) and needed supplemental oxygen therapy (n=2092: 42.1% vs n=1459: 63.6%; p<0.001), NIV (n=643; 12.9% vs n=709; 30.9%; p<0.001) or inotropes/vasoactive drugs (n=108; 2.2% vs n=77: 3.4%; p=0.004). Mortality was higher during the second wave (19.2% vs 9.3%; p<0.001). On multivariable regression analysis, age >60 years (risk ratio, RR 2.80; 95% CI 2.12 to 3.70), D-dimer >1000 ng/mL (RR 1.34; 95% CI 1.15 to 1.55), treatment with supplemental oxygen (RR 14.6; 95% CI 8.98 to 23.6) and presentation during the second wave (RR 1.40; 95% CI 1.21 to 1.62) were independently associated with mortality. CONCLUSION: The second wave of the COVID-19 pandemic in India appeared to be associated with more severe presentation and higher mortality when compared with the first wave. Increasing age, elevated D-dimer levels and treatment with supplemental oxygen were independent predictors of mortality.

Code blue: Predictors of survival.

Background and Aims: Code blue is a rapid response system developed for emergency resuscitation and stabilization of any sudden cardiac arrest (SCA) within a hospital. Literatures on outcome and factors predicting mortality from SCA in the Emergency departments (EDs) of India is scant. Material and Methods: This retrospective cohort study included all patients above the age of 15 years who had a code blue declared in the ED between the months of January 2018 and June 2019. Factors related to the sustained return of spontaneous circulation (ROSC) and mortality were analyzed using descriptive-analytic statistics and logistic regressions. Results: This study included 435 patients with a male predominance of 299 (69%). The mean age was 54.5 (SD - 16.5) years. Resuscitation was not attempted for 18 patients because of the terminal nature of the underlying disease. The majority were in-hospital cardiac arrests (74%). The nonshockable rhythm included pulseless electrical activity (PEA) (85.5%) and asystole (14.5%) cases. Shockable rhythms, that is, pulseless ventricular tachycardia/ventricular fibrillation were noted in only 10% (43/417) of cases. ROSC was attained in 184 (44.1%) patients, among which 56 (13.4%) were discharged alive from the hospital. Multivariate logistic regression analysis showed CPR >10 min (odds ratio [OR]: 13.58; 95% CI: 8.39-22.01; P < 0.001) and female gender (OR: 1.89; 95% CI: 1.13-3.17; P = 0.016) to be independent risk factors for failure to achieve ROSC in ED. Conclusion: The initial documented rhythm was nonshockable in the majority of the cases. CPR duration of more than 10 min and female gender were independent risk factors for failure to achieve ROSC in the ED. Nonshockable rhythms have a poorer outcomes than that of shockable rhythms.

A single - center retrospective observational study on patients undergoing Encephalo-Duro-Arterio -Myo-Synangiosis in patients with moyamoya disease.

BACKGROUND: Many cases of moyamoya disease are refractory to conventional medical therapy, hence surgical revascularization techniques have emerged as one of the primary choices of treatment. In this study, we present the functional and angiographic outcomes of patients undergoing encephalo-duro-arterio-myo-synangiosis (EDAMS). METHODS: This is a retrospective observational cohort study, done over 8 years (2012-2020) in a neurological center in Eastern India. Data were retrieved from the hospital's electronic system, recorded in a standard data abstract sheet, and analyzed. RESULTS: This study included 75 patients, with a male (n = 42; 56.0%) preponderance. Majority belonged to the pediatric age group (≤18 years) (n = 70; 93.3%); remaining adult population included 5 (6.6%) patients. The most common presenting complaint was that of an ischemic cerebrovascular accident (CVA) (n = 57; 76.0%). Symptomatic hemispheres (n = 69; 92.0%) were treated and later followed if they had progressed to bilateral disease formation. Preoperative DSA showed 50 (71.4%) to have Suzuki grade 3 type of angiographic findings. Postoperative complications included worsening unilateral hemiparesis 4 (40%), slurring of speech (n = 2; 20.0%), hematoma (n = 2; 20.0%), and surgical site infection (n = 2; 20.0%). One patient succumbed to his illness on the second postoperative day. A postoperative angiogram showed regression of moyamoya vessels in the majority (n = 69; 93.3%) of patients. All (n = 74; 100%) had an intensification of transdural vessels; none had a regression. None of the study participants showed an intensification of moyamoya vessels. Many of our patients (83.8%) had a good grade of revascularization (modified Matsushima and Inaba A and B), while 16.2% had low-grade revascularization (grade C). On assessing outcomes using a modified Rankin Score, a large number of our patients had an excellent (n = 45, 60%) neurological outcomes. CONCLUSION: There was a bimodal age distribution with most of them presenting with ischemic CVA. This procedure (EDAMS) had good angiographic (Matsushima and Inaba) and functional (modified Rankin Score) outcomes.

A Rare Case Report of an Intradural Left Cerebellopontine Angle Chordoma.

Intracranial intradural chordomas are rare entities constituting 1 to 3% of primary bone tumors. The mainstay of treatment remains aggressive resection of the lesion followed by adjuvant radiation therapy. We hereby report a case of a 70-year-old gentleman with intracranial, intradural chordoma arising from the left cerebellopontine angle. We hope to add to the existing minimal literature on this subject by highlighting this case, the first reported one from Asia.

A Retrospective analysis of the profile of trauma victims presenting to an emergency department in South India.

Background: Trauma is a leading cause of morbidity and mortality in both developed and developing countries. Methodology: This retrospective observational study was done in the Emergency Department (ED) of a tertiary care trauma center in Southern India in 2018 (January to December). Results: During the study period of 1 year, the ED attended 74,466 patients which included 7675 (10.3%) trauma patients. The mean age was 35.3 (SD: 18.5) years with three-fourth (76.6%) being males. Pediatric/adolescents (age ≤18 years) and geriatric age groups (age ≥60 years) comprised 16.7% and 11.8% cases, respectively. Road traffic accidents (RTA) (66%) were the predominant mode of injury followed by falls (fall from height: 8.6% and fall on level ground: 7.8%). Among the RTAs, the majority were two-wheelers related (73.8%), followed by pedestrian injuries (9.4%) and four-wheelers injuries (7.2%). Bivariate and multivariate logistic regression analysis showed pedestrian injuries, low Glasgow Coma Scale (GCS), and hypotension at arrival as independent predictors of hospital mortality. The in-hospital mortality rate was 0.7%. A quarter (24%; n = 1841) of the patient's population was solely managed by the ED team and discharged stable, while 2179 (28.4%) victims required hospital admission. Conclusion: Trauma is a major cause of mortality especially among the breadwinners of families in India with almost half being due to two-wheeler accidents. Efficient ED professionals and a multispecialty team of trauma surgeons, neurosurgeons, and orthopedics handle the major load of acute trauma. Pedestrian injuries, low GCS, and hypotension at arrival are independent predictors of in-hospital mortality.

Three waves, three vaccines, three COVID-19 infections - Saga of a frontline health care worker during the pandemic.

The COVID-19 pandemic affected millions around the globe, with front line healthcare workers (HCW) amongst the most vulnerable. The Emergency Department (ED) was the first line of care for all patients infected with the virus, making HCWs in the ED one of the most exposed populations during the pandemic. We highlight the case of a 35-year-old ED physician who developed COVID-19 infections on three separate instances during the peaks of each wave despite the usage of personal protective equipment and being triple vaccinated.

Does endovascular repair of post-traumatic thoracic vascular injury of the subclavian/axillary arteries followed by brachial plexus injury improve outcome?

Traumatic injuries to the axillary artery or subclavian artery along with a brachial plexus injury are infrequent. Although the traditional management has been conservative because of robust collaterals, the functional improvement of the limb depends on the degree of brachial plexus injury and on the revascularization status. We report three cases of endovascular repair post-traumatic axillo-subclavian artery injuries followed by brachial plexus injury with good functional outcomes. Endovascular repair of post-traumatic subclavian and axillary artery injuries followed by brachial plexus injury is safe and feasible, and improves limb outcomes.

Impact of prior vaccination with CovishieldTM and Covaxin® on mortality among symptomatic COVID-19 patients during the second wave of the pandemic in South India during April and May 2021: a cohort study.

BACKGROUND: COVID-19 vaccines were authorised for emergency use to mitigate the impact of the pandemic. This study evaluated the effect of prior vaccination with either Oxford Astra Zeneca's Covishield™ or Bharath Biotech's Covaxin® on mortality among symptomatic COVID-19 patients during the second wave of the pandemic in India. METHODOLOGY: In this cohort study comprising of RT-PCR confirmed symptomatic COVID-19 patients presenting during April and May 2021, the effect of prior vaccination on mortality (primary outcome), need for hospitalization, oxygen therapy, non-invasive ventilation (NIV) and intensive care unit (ICU) admission were assessed and expressed as risk ratio (RR) with 95% confidence intervals (CI). RESULTS: The mean (SD) age of the cohort (n = 4183) was 46.3 (15.5) years; 17.9% (748/4183) had received at least one dose of Covishield™ and 4.8% (201/4183) had received Covaxin®. Mortality was 0.2% (95% CI: 0.2% - 0.7%), 3.5% (1.9-5.2%), 6.2% (0.3-12%) and 12.9% (11.8-14.1%) among fully vaccinated (>2 weeks after two doses), partially vaccinated (>2 weeks after one dose or <2 weeks after two doses), indeterminate (<2 weeks after one dose) and unvaccinated patients respectively. The difference in mortality among unvaccinated vs. fully vaccinated was 12.7% (95% CI: 11.4-13.9%), unvaccinated vs. partially vaccinated was 9.4% (7.4-11.4%) and unvaccinated vs. indeterminate vaccinated was 6.8% (0.8-12.7%). On adjusted analysis, as compared to unvaccinated patients, at least one dose of vaccine reduced the need for hospitalization (RR: 0.40; 95% CI: 0.35-0.47), oxygen (0.33; 0.27-0.40), NIV (0.23; 0.17-0.32), ICU admission (0.18; 0.12-0.27) and mortality (0.18; 0.11-0.29). CONCLUSION: Among symptomatic COVID-19 patients, prior vaccination with Covishield ™ or Covaxin® impacted the severity of illness and reduced mortality during a period of widespread delta variant circulation. Full vaccination conferred greater protection than partial vaccination.

Differentiating Cardiac and Pulmonary Causes of Dyspnea Using Ultrasonography and Dyspnea Discrimination Index.

BACKGROUND: One of the most common reasons for emergency room (ER) visits is acute dyspnea. The challenge is in differentiating a cardiac and pulmonary cause of acute breathlessness. Hence, we have studied the effectiveness of the dyspnea discrimination index (DDI) used in conjunction with ultrasonography (USG) in distinguishing between cardiac and pulmonary causes of dyspnea. METHODS: This was a prospective study conducted in the ER and general medicine wards to evaluate the efficacy of the DDI and USG in dyspneic patients. Data were entered in a standard data sheet and analysis was done using SPSS software. RESULTS: The majority of the patients were between the ages of 45 and 60, with a male predominance. Risk factors like smoking were more common in the pulmonary group (36%). Pulmonary cause of breathlessness was seen in 62% of patients and cardiac pathology was noted in 28%. The mean (SD) DDI value and DDI% are as follows: pulmonary group (DDI)-5.47 (SD: 2.82); cardiac group (DDI)-8.34 (SD: 3.75); pulmonary group (DDI%)-1.31 (SD: 0.68); cardiac group (DDI%)-2.34 (SD: 1.14). There was a significant difference in DDI% between the pulmonary and cardiac groups (p = 0.001). DDI was found to have a sensitivity and specificity of 77.3% and 70%, respectively. While for DDI%, sensitivity and specificity were 72.7% and 72%, respectively. Lung USG had 98% sensitivity and 95.5% specificity, with a narrow confidence interval. The positive likelihood ratio was noted to be 21.6, indicating a very high post-test probability. CONCLUSION: The DDI and USG in conjunction had good discriminative power, when it came to distinguishing between cardiac and pulmonary causes of dyspnea. USG had a high specificity and sensitivity, making it suitable for identifying the cause of dyspnea in a tertiary care ER setting.

Severe or not so severe? The gravity of geriatric trauma.

BACKGROUND: Due to associated comorbidities, the elderly population is more vulnerable to injuries with complications. This study was done to assess the severity of trauma and outcome of injuries among these patients presenting to the Emergency Department (ED). MATERIALS AND METHODS: This was a retrospective cohort study. We included all patients aged more than 60 years, who presented to the ED with trauma in the year 2018. Details of the mode of trauma, severity of injuries and outcome were analysed. RESULTS: During the study period a total of 7666 trauma patients presented to ED, among which 879 (879/7666: 11.4%) were in the geriatric age group. The mean age was 68.9 (SD: 7) years with 90.8% being young-old (60-79 years) and 9.2% being old-old (>80 years). Common modes of injuries were road traffic accidents (RTA) (64%) fall on level ground (FLG) (20%) and fall from height (FFH) (8%). Most of them had Injury Severity Score (ISS) and New Injury Severity Score (NISS) score of 0-7, i.e.: 62% and 51%, respectively. On multivariate logistic regression analysis RTA, FFH FLG and triage priority 1 patients were associated with trauma in the old-old as compared to the young-old age groups significantly. Independent risk factors associated with severe trauma were seen RTA, FLG and priority 1 patients. Forty-four per cent patients were managed by the ED team alone. Trauma speciality departments referred to included orthopaedics (47%), neurosurgery (22%), trauma surgery (14%), plastic surgery (8%) and hand reconstruction surgery (6%). About half of the population under study was discharged stable (44%), of which the majority belonged to the young-old category (44.1%). The in-hospital mortality rate was 0.5% (4/879). CONCLUSION: This study shows the gravity of multiple injuries sustained by the geriatric age group with RTA, FLG and FFH being the predominant causes of trauma. The NISS highlights the severity of injuries in the old and the frail.
