Noninvasive Respiratory Assist Devices in the Management of COVID-19-related Hypoxic Respiratory Failure: Pune ISCCM COVID-19 ARDS Study Consortium (PICASo).

Objective: To determine whether high-flow nasal oxygen (HFNO) or noninvasive ventilator (NIV) can avoid invasive mechanical ventilation (IMV) in COVID-19-related acute respiratory distress syndrome (ADRS), and the outcome predictors of these modalities. Design: Multicenter retrospective study conducted in 12 ICUs in Pune, India. Patients: Patients with COVID-19 pneumonia who had PaO2/FiO2 ratio <150 and were treated with HFNO and/or NIV. Intervention: HFNO and/or NIV. Measurements: The primary outcome was to assess the need of IMV. Secondary outcomes were death at Day 28 and mortality rates in different treatment groups. Main results: Among 1,201 patients who met the inclusion criteria, 35.9% (431/1,201) were treated successfully with HFNO and/or NIV and did not require IMV. About 59.5% (714/1,201) patients needed IMV for the failure of HFNO and/or NIV. About 48.3, 61.6, and 63.6% of patients who were treated with HFNO, NIV, or both, respectively, needed IMV. The need of IMV was significantly lower in the HFNO group (p <0.001). The 28-day mortality was 44.9, 59.9, and 59.6% in the patients treated with HFNO, NIV, or both, respectively (p <0.001). On multivariate regression analysis, presence of any comorbidity, SpO2 <90%, and presence of nonrespiratory organ dysfunction were independent and significant determinants of mortality (p <0.05). Conclusions: During COVID-19 pandemic surge, HFNO and/or NIV could successfully avoid IMV in 35.5% individuals with PO2/FiO2 ratio <150. Those who needed IMV due to failure of HFNO or NIV had high (87.5%) mortality. How to cite this article: Jog S, Zirpe K, Dixit S, Godavarthy P, Shahane M, Kadapatti K, et al.

Intravenous Methylene Blue as a Rescue Therapy in the Management of Refractory Hypoxia in COVID-19 ARDS Patients: A Case Series.

Objectives: To describe the clinical outcomes of hypoxic coronavirus disease 2019 (COVID-19) patients treated with intravenous methylene blue (MB) in a tertiary care hospital. Materials and methods: We conducted a case series of 50 patients with hypoxic COVID-19 treated with intravenous MB admitted to our hospital between June 01 and September 10, 2020. Intravenous MB was administered as rescue therapy in dosage of 1 mg/kg body weight, with a maximum of five doses, to patients with high oxygen requirements (SpO2/FiO2 <200) apart from the standard of care after obtaining G6PD levels. Data were abstracted from multiple electronic data sources or patient charts to provide information on patient characteristics, clinical and laboratory variables and outcomes. Results: The median age of the patients was 53.3 (range 25-74 years) and most patients (74%) were men. About 68% of patients had pre-existing comorbidity. Median SpO2/FiO2 ratio progressively improved from 132.5 (predose) to 284 before the terminal event (death or discharge), ventilator-free days, and decrease in the proinflammatory biochemical parameter was significantly higher after the second dose of MB. A total of six patients out of 50 required invasive mechanical ventilation (IMV). Thirty patients were discharged with a recovery rate of 60%, while 20 patients succumbed to the illness. There was no major side effect or adverse event reported in any of the patients. Conclusion: MB due to its polypharmacological action against SARS-CoV-2, an inexpensive and widely available drug with minimal side effects, has a significant potential in the treatment of COVID-19.

COVID-19 Combat Fatigue among the Healthcare Workers: The Time for Retrospection and Action.

The present pandemic caused by the novel coronavirus has battered the healthcare infrastructure all around the globe. The doctors, nurses, and healthcare staff-the COVID warriors-have plunged themselves in line of fire to keep the population safe and alive. Around 87,000 healthcare workers (HCWs) have been infected and 573 have died till August in India alone. With no sight of pandemic ebbing anytime soon and patient load in hospitals refusing to come down, combat fatigue has set in these HCWs. The very people whose life mission is caring for others are on the verge of collective collapse physically and emotionally. There is an urgent need to retrospect the problems faced by the HCWs in the previous months, recognize, and preventive measures initiated at the earliest to prevent further loss and burnout among these battle-hardened frontline soldiers.

A Retrospective Observational Study of Hypoxic COVID-19 Patients Treated with Immunomodulatory Drugs in a Tertiary Care Hospital.

OBJECTIVES: To describe the demographics and evaluate the clinical outcomes of hypoxic coronavirus disease-2019 (COVID-19) patients treated with different immunomodulatory (IM) drugs in a resource-limited setting. MATERIALS AND METHODS: We conducted a retrospective cohort study of these patients admitted to our hospital between March 22 and May 31, 2020. Data were abstracted from multiple electronic data sources or patient charts to provide information on patient characteristics, clinical, laboratory variables, and outcomes. RESULTS: A total of 134 patients met the inclusion criteria and were followed up till June 7, 2020. The median age of the patients was 55.6 years (range 20-89 years) and 68% were men. At least one comorbidity was seen in 72% of the patients with diabetes (44%) and hypertension (46%) being the most common. At triage, fever (82%), shortness of breath (77%), and cough (61%) were the most common presenting symptoms. A PaO2/FiO2 ratio less than 300 was seen in 60%, and 4.5% required invasive mechanical ventilation within 72 hours of hospital admission. Five immunomodulatory agents (hydroxychloroquine, methylprednisolone, colchicine, etoricoxib, and tocilizumab) were administered in different combinations. Overall, in-hospital mortality was 26.9%, and 32% required mechanical ventilation. Around 69% of patients were discharged home. Five variables (SpO2, PaO2/FiO2 ratio, leucocytosis, lymphopenia, and creatinine) on admission were found to be significant in the patients who died. CONCLUSION: Our study provides the characteristics and outcomes of hypoxic COVID-19 patients treated with IM drugs in varied combination. Five independent variables were strong predictors of mortality. HOW TO CITE THIS ARTICLE: Mahale N, Rajhans P, Godavarthy P, Narasimhan VL, Oak G, Marreddy S, et al.

Preparedness of Acute Care Facility and a Hospital for COVID-19 Pandemic: What We Did!

BACKGROUND AND AIM: India is facing the pandemic of coronavirus disease (COVID-19) just like the whole world. The private sector is the backbone of a healthcare facility in India. Presently, only a few major hospitals in the country are actively dealing with the COVID-19 patients while others are facing troubles due to lack of manpower, management, and required experience to face the pandemic. Despite the lockdown, the cases are ever increasing and each and every hospital in the country should be prepared to face this pandemic the world has never seen before. As one of the largest multispecialty hospitals and a designated COVID center, we have developed and adopted some strategies for better preparedness to face the surge of this pandemic. We would like to share our experience and hope that the strategies laid down and adopted by us will help many other acute care facilities in many parts of India. MATERIALS AND METHODS: Different strategies are adopted to deal with the crisis situation of the COVID-19 pandemic. Our adopted strategies were directed to mitigate the challenges of administration, hospital space organization, management of staff and supplies, maintenance of standard of care, and specific COVID care and ethics during this pandemic. RESULTS: Based on strategies adopted by us, we feel more confident and prepared to deal with COVID-19 pandemic. CONCLUSION: Our approach for preparing for the COVID-19 pandemic may not be the best one but we believe that the basic managerial principles we adopted will guide many other institutions to find their path in tackling the pandemic in the best possible way.
