RESUMO
BACKGROUND AND OBJECTIVE: We compared the overall clinical outcome in formula-based protocol (1:1:1) and thromboelastogram (TEG)-guided goal-based massive transfusion (MT) in the resuscitation of patients with hemorrhagic shock. MATERIALS AND METHODS: This was a retro-prospective case-control study conducted over a period of 2 years among the patients who received MT using a 1:1:1 fixed ratio protocol (controls, Group A) and goal-based protocol (cases, Group B) guided through TEG. Patients were matched for the type and severity of the clinical conditions. Utilization of blood components, clinical outcomes, transfusion-related complications, and total mortality rates were compared between the groups. RESULTS: There were 113 patients in the formula-based group and 109 patients in the goal-based transfusion group who were matched for injury severity scores. The total blood components utilized were 1867 and 1560, respectively, with a 17.7% reduction associated with the use of TEG. Patients were divided into normal, hypo, and hypercoagulable based on TEG, and a higher transfusion rate was associated with hypocoagulable TEG (942 vs. 610). The prothrombin time, activated partial thromboplastin time, R time, and K time had a significant positive correlation with the need to transfuse more than 20 blood components, whereas platelet count, base excess, alpha angle, MA, and CI had a negative correlation (r = 0.268, P < 0.001). At the end of goal-directed transfusion, 75% of the patients were free of transfusion support (vs. 65.4%) and only 6.9% of the patients had coagulopathy (vs. 31.8%) compared to formula-based resuscitation with a 10% reduction in mortality. CONCLUSION: TEG-guided goal-based approach helped to reduce blood component utilization with a reduced incidence of coagulopathy at the end of the MT while improving patient survival.
RESUMO
This study examined the organizational culture of an emergency medicine department (EMD) in a tertiary hospital in Karnataka, India, using a prospective cross-sectional design from January to February 2024. It aimed to identify the predominant and supporting organizational cultures within the EMD and their influence on employee behavior and well-being, including job satisfaction, burnout, stress levels, and coping strategies. A total of 82 participants, including physicians, emergency medical technicians, and nurses, completed the Organizational Culture Assessment Instrument (OCAI) and a self-designed questionnaire. Ethical clearance was obtained (IEC2-656). Clan culture emerged as the dominant culture (73.17%), emphasizing collaboration and adaptability, correlated with lower stress levels and high job satisfaction (90.78%). Emotional exhaustion was the most common burnout symptom (53.66%). The coping strategies varied, with employees in Clan cultures seeking social support, while those in Hierarchy cultures sought guidance from superiors. This study highlighted the significant role of organization culture in employee well-being and EMD effectiveness, influenced by social values like respect for authority. The limitations included single-setting analysis, an uneven subgroup representation, and a lack of qualitative insights. Future research should involve multiple hospitals and qualitative methods for a comprehensive understanding.

Introduction: CPR is an important lifesaving skill that can improve outcomes of patients in cardiac arrest. Mass training of hands-only CPR is one of the ways to spread information and teach this skill. Need for expensive CPR mannequins are a limiting factor in conducting such mass training programmes. This study assessed the effectiveness of a low-cost CPR pillow model in training hands-only CPR. Methodology: Two hundred and six undergraduate students underwent a two-hour CPR training session. They were randomly divided into two groups - mannequin group and CPR pillow group and practiced hands-only CPR on a standard mannequin and a low-cost CPR pillow model, respectively. Knowledge, attitude, and skill acquisition were objectively assessed and compared between the two groups. Results: There was no statistical difference in hand positioning, chest compression rate and fraction, depth and overall CPR score between the two groups trained via mannequin and CPR Pillow (P > 0.05). The CPR pillow group had better percentage of chest recoil as compared to the mannequin group (86% vs 73%; P < 0.001). Conclusion: The use of low-cost homemade CPR devices such as our CPR pillow model is an acceptable alternative to mannequin for training hands-only CPR to lay rescuers.
RESUMO
The Acute Physiology and Chronic Health Evaluation II (APACHE II) scoring system is utilised as a prognostic method in paraquat poisoning; however, current evidence shows ambiguity. Although some studies have shown APACHE II to be a superior tool, others have reported it inferior to other prognostic markers, such as lactate, severity index of paraquat poisoning and urine paraquat concentration. Hence, to address this ambiguity, we conducted a systematic review and meta-analysis to analyse prognostic accuracy of APACHE II score in predicting mortality in paraquat poisoning. We included twenty studies with 2524 paraquat poisoned patients in the systematic review, after a comprehensive literature search in databases PubMed, Embase, Web of Science, Scopus and Cochrane Library, from which 16 studies were included in the meta-analysis. The survivors of paraquat poisoning were found to have significantly lower APACHE II scores (Mean Difference (MD): -5.76; 95% CI: -7.93 to -3.60 p < 0.0001; n = 16 studies) compared to non-survivors. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR) and diagnostic odds ratio (DOR) for APACHE II score <9 was found to be 74%, 68%, 2.58, 0.38 and 7.10, respectively (n = 5 studies). The area under the curve (AUC) of the bivariate summary receiver operating characteristic (SROC) curve was found to be 0.80. The pooled sensitivity, specificity, PLR, NLR and DOR for APACHE II score ≥9 was found to be 73%, 86%, 4.69, 0.33 and 16.42, respectively (n = 9 studies). The AUC of the SROC curve was found to be 0.89. Pairwise AUC comparison of APACHE II with other prognostic markers showed serum presepsin to have a significantly better discriminatory ability than APACHE II. Through the findings of this study, we conclude that APACHE II was found to be a good indicator of death in paraquat poisoning patients. However, higher APACHE II scores (≥9) depicted greater specificity in predicting mortality in paraquat poisoning. Thus, APACHE II can be used as a practical tool in the hand of physicians to prognose patients with paraquat poisoning to aid clinical decisions.

Background: The coronavirus disease-2019 (COVID-19) pandemic has brought about a change in healthcare practices that are likely to persist into the foreseeable future. In particular, is the exposure risk to the healthcare practitioners in the emergency department (ED) and the intensive care units. Mitigating this issue in a low-resource setting remains challenging, and in particular, in developing nations such as India, where ED patient flows can overwhelm a system and its human resources, breaking down processes and infecting healthcare workers (HCWs). Technique: To tackle this and the possible lack of appropriate personal protective equipment (PPE), we designed and built biosafety barrier devices using local resources for use in patient stabilization, transport, and continued care in the ED or the intensive care units. Results: Four biosafety devices bio-safe levels 1 and 2, ultra-ductile portable interface of interventions in infections, and tented transport trolley for transmissibility (4T) were tested for the feasibility of usage for patient care during the pandemic with simulation. Conclusion: We anticipate that with time it may be common practice for in situ isolation of patients in the emergency departments with a suspicion of an infectious disease. With the proof of concept, simulation, hospital infection control committee (HICC) approval, and trial run, we look to close the gaps that exist in these initial innovations.

RESUMO
Objectives: Palliative care (PC) referral in serious and critical COVID-19 improves decision-making, health resource utilisation, end-of-life symptom management and family support. In this study, we explored developing a systematic decision-making matrix for PC referral in COVID-19 and audited its outcomes. Materials and Methods: A team of interdisciplinary experts developed a hospital COVID-19 PC plan. PC referral and outcomes of PC referral in hospitalised COVID-19 patients were audited. Results: Out of 1575 inpatients, 1066 (67.7%) had mild and 509 (32.3%) had serious and critical COVID-19 illness. Among 50 (3.1%) referred to PC, 5 (0.4%) had mild and 45 (8.8%) had serious and critical COVID-19 illness. Out of 45 serious and critical COVID-19 patients referred to PC, 38 (84%) received end-of-life care (EOLC), 4 (9%) self-discharged against medical advice and 3 (7%) recovered. Forty-seven (94%) were referred for goals-of-care discussion. About 78% received opioids, 70% benzodiazepines and 42% haloperidol for symptom management. Among 45 serious and critical COVID-19 patients referred to PC, foregoing life-sustaining treatment was documented in 43 (96%) but implemented only in 23 (53%). Out of 38 who received EOLC, ICU was the place of death in 31 (82%) and ward in 7 (18%). Conclusion: Despite interdisciplinary experts developing a hospital COVID-19 PC, low referral of serious and critical COVID-19 patients to PC was observed. PC referral enabled access to management of end-of-life symptoms and facilitated limitation of life-sustaining treatment in some COVID-19 patients with serious illness. Educating critical care physicians about the scope of PC in the COVID-19 setting might improve PC referral.
RESUMO
BACKGROUND: COVID-19 associated coagulopathy (CAC) can either be localized or systemic hypercoagulable state with increased risk of thromboembolism. This study looked into the usefulness of Thromboelastography (TEG) and the velocity curve (V-curve) derivative from TEG in diagnosing and differentiating different stages of CAC. MATERIALS AND METHODS: A prospective single cohort study of RT-PCR confirmed COVID-19 patients was carried out for 2 weeks. Severe COVID-19 patients in the adult critical care units with a TEG report were recruited for the study. Citrated kaolin TEG was performed on the day of admission before anticoagulation. TEG parameters included were R and K time, alpha angle, maximum amplitude, clotting index, lysis at 30 min. The first-degree velocity curve of TEG is plotted as V-curve which extrapolates thrombus generation potential. Parameters analyzed were the maximum rate of thrombus generation as well as thrombus generated (TG). RESULTS: The study included 43 patients with an average age of 58.34 (±15.35). TEG as well as V-curve of all the patients were hypercoagulable compared with age-matched reference range. We had 79.06% of patients in hypercoagulable stage. The mortality rate was 32.56% and 30.23% developed thrombotic incidents. Patients who succumbed to death had prolonged PT, aPTT, MA, Ly30, with a reduced TG (p < .05). The presence of fibrinolysis was associated with thromboembolism (OR = 6.76, CI = 1.48-25.82). Repeat TEG was done randomly in 11 patients and revealed a persistent hypercoagulable stage with increasing fibrinolysis activity. CONCLUSION: TEG is a useful tool in diagnosing and categorizing Coagulopathy associated with COVID-19.

OBJECTIVE: Emergency medicine being a young specialty in India, we aimed to assess the level of disaster preparedness and planning strategies among various academic emergency departments (EDs) across India during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: A cross-sectional multicentric survey was developed and disseminated online to various academic EDs in India and followed up over a period of 8 wk. All results were analyzed using descriptive statistics. RESULTS: Twenty-eight academic emergency medicine departments responded to the study. Compared with pre-COVID period, COVID-19 pandemic has led to 90% of centers developing separate triage system with dedicated care areas for COVID suspected/infected in 78.6% centers with nearly 70% using separate transportation pathways. Strategizing and executing the Institutional COVID-19 treatment protocol in 80% institutes were done by emergency physicians. Training exercises for airway management and personal protective equipment (PPE) use were seen in 93% and 80% centers, respectively. Marked variation in recommended PPE use was observed across EDs in India. CONCLUSIONS: Our study highlights the high variance in the level of preparedness response among various EDs across India during the pandemic. Preparedness for different EDs across India needs to be individually assessed and planned according to the needs and resources available.

BACKGROUND: Management of acute pulmonary hypertension in the Emergency Department(ED) can be challenging. The treatment is specialised, requires rapid identification and correction of the precipitating cause; failing which the patient enters a vortex of deterioration. We describe a lesser-known cause for the same, Thiamine responsive acute pulmonary hypertension (TRAPH) syndrome where timely appropriate treatment can result in dramatic improvement. METHODOLOGY: Medical records with ICD code E51.12 (Wet Beriberi) from Mar 2018 to Mar 2020 were screened. The data regarding presenting symptoms, initial vitals, lab and radiological investigations, and treatment received were retrieved from patient files and the Hospital Informatics System, entered into an MS Excel sheet and compared. RESULTS: The study includes eight cases, which we believe to be TRAPH syndrome. Majority were young adult males, ethanol users. All patients presented with acute shortness of breath with tachypnea and shock index more than 0.9. Gross right atrioventricular dilatation, tricuspid regurgitation and mild to moderate pulmonary arterial hypertension was identified in echocardiography. The initial blood gas revealed median pH 6.98 (IQR 6.81-7.09), Bicarbonate 3.4 meq/L (IQR 2.5-5) and lactate 172 mg/dL (IQR 132-200) which improved within 12-16 h of admission. Patients received median 400 mg IV Thiamine. The mean duration of ICU stay was 2.5 days and total hospital stay was 7 days. CONCLUSION: Thiamine Responsive Acute Pulmonary Hypertension (TRAPH) Syndrome is an under-recognised entity which should be included in differentials for acute right ventricular dysfunction in the ED. Early diagnosis and rapid protocolised management of the same can cause quick recovery of patients.

The objective of this prospective observational study was to assess the door-to-balloon time (D2B), in acute ST-segment elevation myocardial infarction (STEMI) patients and the time factors influencing it. The following timeframes were measured during the study: ED to ECG time, ED to coronary care unit time (ED2CCU), consent time, post-consent to balloon time (POSTCONSENT2B) and D2B. Effective D2B was 54 ± 12.2 min. Of the dependent variables, D2B had a strong positive correlation (ρ = 0.903) with consent time. This study sheds light on consent time a previously unrecognized entity as a significantly influencing factor for the D2B time.

BACKGROUND: Uncorrected maternal hypotension occurring during obstetric emergencies may result in maternal and fetal morbidity. Fluid status of the pregnant mother is a major variable which affects the maternal hemodynamics during patient management, and there is no objective assessment tool for the same. A relatively new sonographic parameter, the inferior vena cava aorta (IVC/Ao) diameter index or caval aortic index, showed promise in this regard, and its application was studied in obstetric patients. METHODOLOGY: A prospective analytical study was conducted involving 50 pregnant and 50 nonpregnant women of reproductive age group. Using both subxiphoid and transhepatic views, their normal fasting caval aortic indices were determined from the ratio of mean IVC diameter to the mean aortic diameter. Descriptive and inferential statistical analyses were carried out accordingly. RESULTS: Normal IVC/Ao diameter index for nonpregnant healthy women of reproductive age was 1.11 ± 0.29 in the subxiphoid view and 1.21 ± 0.33 in the transhepatic view. The difference between the two views was not statistically significant. IVC/Ao diameter index for a normal term pregnant woman was 1.03 ± 0.26, and term pregnancy does not significantly cause variation in the index. CONCLUSIONS: Caval aortic index is a useful noninvasive tool to assess volume status and guide fluid management in pregnant women presenting to the emergency department, and the transhepatic view is comparable to the traditional subxiphoid view for the measurement of the same.
RESUMO
Coronavirus disease 2019 (COVID-19) was an impetus for a multitude of transformations - from the ever-changing clinical practice frameworks, to changes in our execution of education and research. It called for our decisiveness, innovativeness, creativity, and adaptability in many circumstances. Even as care for our patients was always top priority, we tried to integrate, where possible, educational and research activities in order to ensure these areas continue to be harnessed and developed. COVID-19 provided a platform that stretched our ingenuity in all these domains. One of the mnemonics we use at SingHealth in responding to crisis is PACERS: P: Preparedness (in responding to any crisis, this is critical) A: Adaptability (needed especially with the ever-changing situation) C: Communications (the cornerstone in handling any crisis) E: Education (must continue, irrespective of what) R: Research (new opportunities to share and learn) S: Support (both physical and psychological). This article shares our experience integrating the concept of simulation-based training, quality improvement, and failure mode analysis.
RESUMO
CONTEXT: The guideline recommended dose of intravenous (i.v) recombinant tissue-type plasminogen activator (rt-PA) for acute ischemic stroke is 0.9 mg/kg in the European and American populations. In Asiatic population, some studies have shown that a lower dose of i.v rt-PA is equally efficacious. AIMS: To assess if there is a need for a dose optimization for i.v rt-PA study among Indians. SETTING AND DESIGN: A prospective, observational database of acute stroke cases that presented to a tertiary care institute over a period of 1 year was made. METHODS: The data procured using a prestructured elaborate pro forma. Based on the dose of rt-PA received, the individuals were divided into three groups; Group 1 (0.6-0.7 mg/kg), Group 2 (0.7-0.8 mg/kg), and Group 3 (0.8-0.9 mg/kg). Improvement was assessed in each group and between the thrombolysed and nonthrombolysed individuals. STATISTICAL ANALYSIS USED: The nonparametric Mann-Whitney U-test (Wilcoxon rank-sum test) was applied for assessing improvement of National Institutes of Health Stroke Scale score with significance level of α < 0.05 (P < 0.012) and compliance level at 95%. RESULTS: Between the thrombolysed (n = 46) and nonthrombolysed (n = 113) group, there was a statistically significant neurological improvement in the thrombolysed group. Clinical improvement was noted in 75%, 85.7%, and 66.7% of individuals receiving rt-PA in Groups 1, 2, and 3, respectively. Four out of the five who developed a clinically significant intracranial hemorrhage were thrombolysed at a dose of 0.8-0.9 mg/kg rt-PA (Group 3). CONCLUSION: There is a need for a properly randomized, dose optimization study of i.v rt-PA in the Indian subcontinent.
RESUMO
BACKGROUND AND PURPOSE: The purpose of this study was to assess factors causing delay in treatment of acute stroke in a tertiary care institute in South India. METHODS: All clinically suspected cases of acute stroke presenting to the emergency department over a period of 1 year were prospectively followed up and data collected as per a preset pro forma. The various time intervals from stroke onset to definitive management and other pertinent data were collected. The time delays have been evaluated in the decision tree model: Chi-squared Automatic Interaction Detection. Significance was assessed at 5% level of significance (P < 0.05). RESULTS: The mean prehospital time delay for all clinically suspected stroke (n = 361) in our institute was 716 min and the median time 190 min. The mean total in-hospital delay was 94.17 ± 54.5 min and median time being 82 min. The onset of symptoms to first medical contact was the main interval that influenced the prehospital delay. Computed tomographic (CT) diagnosis to stroke unit admission influenced the in-hospital delay the most. CONCLUSIONS: Lack of awareness regarding stroke leads to delayed seeking of treatment for the same. The factors that contribute to the in-hospital delay included patient admission procedure delay, lack of staff to transport the patient, and the distance between the stroke unit and CT room. Educating the community with regard to "stroke" and implementation of a better pre- and in-hospital stroke care system is a need of the hour in the country.
