Thanks Dr Prashant Ved for the update . Wuhan had been the epicenter of COVID- 19 .Experience of doctors there is much more in handling COVID-19 patients. This regimen had been followed successfully in Wuhan. Most critically ill patients with COVID- 19 respond well to prone ventilation, with a rapid improvement of Oxygenation and lung mechanics .Prone ventilation is recommended as a routine strategy for patients with PaO2/FiO2 <150 mmHg or with obvious imaging manifestations with out contraindications. Time course recommended for prone ventilation is more than 16 hours each time .The prone ventilation can be stopped once PaO2/FiO2 is greater than 150 mmHg for than 4 hours in the supine position. Prone ventilation while awake may be attempted for patients who have not been intubated or have no obvious respiratory distress but with impaired oxygenation or have consolidation in gravity dependent lung zones on lung images .Procedures for at least 4 hours each time is recommended. Prone position can be considered several times per day depending upon the effects and tolerance. Thanks
Yeah and the ECMO technique of providing prolonged cardiac and respiratory support to persons whose heart and lungs are unable to provide an adequate amount of gas exchange or perfusion to sustain life. So in Wuhan this technique is also used.
Prone position gives better and more oxygen saturation as compred to supine position.valuable position
Good. Thanks. Informative
Valuable and information post.
Very interesting any thing which helps in treatment & prognosis must try
Agreed with Dr.Parveen Yogiraj
Really very effective method sir.....thanks for reminding us again....

THE COVID-19 SYMPTOMS WE DID NOT KNOW ABOUT As the pandemic spreads around the world, doctors are beginning to scope the coronavirus’s damage. Seen initially as a cause of viral pneumonia during the chaos of an explosion of cases in China, it’s now emerging as an enigmatic pathogen capable of harming the body in a myriad of unexpected, and sometimes lethal, ways. Clinical manifestations range from common cold-like symptoms and bronchitis to more severe disease such as pneumonia, severe acute respiratory distress syndrome, multi-organ failure and even death. The illness may occur as a direct result of viral infection, as well as the body’s response to it. Here’s a snapshot of some of the symptoms Covid-19 causes, including some you might not have heard about. Blood Fever and inflammation may disrupt blood vessels, rendering blood cells more prone to clumping while interfering with the body’s ability to dissolve clots. That may trigger a clotting cascade that can lead to blood-vessel blockages in tissues and organs throughout the body. Life-threatening clots in the arteries of the lung, known as pulmonary emboli, may occur even after symptoms of the infection have resolved. Damaged blood vessels may become leaky and prone to bleeding. In children, inflammation of veins and arteries triggered by excessive immune activation may cause an illness similar to Kawasaki disease, an inflammatory disorder. Brain Dysfunction in the lining of blood vessels and associated bleeding and clotting disorders may cause strokes and bleeding in the brain. Patients may also experience headache, dizziness, confusion, impaired consciousness, poor motor control, delirium and hallucinations. Eyes Red, puffy eyes, sometimes referred to as pink eye, may result from infection in the conjunctiva, the tissue that lines the inside of the eyelids and covers the white part of the eye. Gastrointestinal tract Infection of cells lining the digestive tract may cause diarrhea, nausea, vomiting and abdominal pain. Blood-vessel blockages caused by abnormal clotting have been found to damage the bowel, requiring emergency surgery and resection. Hands Prickling or burning sensation in the hands and limbs may indicate Guillain-Barré syndrome, a rare nervous-system disorder that may be triggered by aberrant immune responses to viral infection. Other symptoms of the syndrome include poor coordination, muscle weakness and temporary paralysis. Heart Cardiac injury, sometimes leading to irregular heartbeat, heart failure, and cardiac arrest, may occur as a result of excess strain, inflammation of the heart muscle and coronary artery, blood clots, and overwhelming multi-organ illness. Infection, fever, and inflammation in people with existing heart-vessel blockages may cause their fatty plaques to break off, blocking or stopping blood flow in organs and tissues. Limbs Obstructions in large blood vessels may cause insufficient flow, or acute ischemia, in the limbs. Severe vascular complications can be lethal. At least one reported cases resulted in lower limb amputation. Liver Liver dysfunction may occur as a direct result of the viral infection, or more likely because of immune-mediated, systemic inflammation and circulatory blockages cutting blood flow to the organ. Lungs The virus targets the epithelial cells that line and protect the respiratory tract as well as the walls of the tiny grape-like air sacs, or alveoli, through which gas exchange occurs to oxygenate the blood. Damage to alveoli and inflammation in the lungs can cause pneumonia, characterized by chest pain and shortness of breath. In severe cases, the lack of oxygen can trigger acute respiratory distress syndrome, leading to multi-organ-system failure. Kidneys Acute kidney injury may result from clots and impaired blood supply, or as a direct result of infection. Nose and tongue While the virus can cause the sneezing and runny nose typical of a common cold, it can also disrupt the olfactory system, causing an abrupt full or partial loss of the sense of smell known as anosmia. Taste may also become distorted in a condition known as dyguesia. Skin Hive-like rashes, small red dots and purplish discolorations on the legs and abdomen are part of a complex category of so-called paraviral dermatoses that may result from the body’s immune response to the virus or from benign, superficial blood-vessel damage beneath the skin. Toes Purple rashes that resemble chickenpox, measles or chilblains may appear on the feet, especially of children and younger adults.Dr. Prashant Ved17 Likes21 Answers

Hello everyone, Here are some important facts about COVID-19. From Clinical presentations to treatment. Please check it out and feel free to add more points. CLINICAL PRESENTATION: In a study describing 1099 patients with COVID-19 pneumonia in Wuhan, the most common clinical features at the onset of illness were: •Fever in 88% •Fatigue in 38% •Dry cough in 67% •Myalgias in 14.9% •Dyspnea in 18.7% Pneumonia appears to be the most common and severe manifestation of infection. In this group of patients breathing difficulty developed after a median of five days of illness. Acute respiratory distress syndrome developed in 3.4% of patients. Other symptoms •Headache •Sore throat •Rhinorrhea •Gastrointestinal symptoms About 80% of confirmed COVID-19 cases suffer from only mild to moderate disease and nearly 13% have the severe disease (dyspnea, respiratory frequency ≥30/minute, blood oxygen saturation≤93%, PaO2/FiO2 ratio <300, and/or lung infiltrates >50% of the lung field within 24-48 hours). Critical illness (respiratory failure septic shock, and/or multiple organ dysfunction/failure) is noted in only in less than 6% of cases. INCUBATION PERIOD: The exact incubation period is not known. It is presumed to be between 2 to 14 days after exposure, with most cases occurring within 5 days after exposure. THE SPECTRUM OF ILLNESS SEVERITY: Most infections are self-limiting. COVID-19 tends to cause more severe illness in the elderly population or in patients with underlying medical problems. As per the report from the Chinese center for disease control and prevention that included approximately 44,500 confirmed Infections with an estimation of disease severity. • Mild illness was reported in 81% of patients. • Severe illness (Hypoxemia, >50% lung involvement on imaging within 24 to 48 hours) in 14%. • Critical Disease (Respiratory failure, shock, multi-organ dysfunction syndrome) was reported in 5 percent. • Overall case fatality rate was between 2.3 to 5%. AGE AFFECTED: • Mostly middle-aged (>30 years) and elderly. • Symptomatic infection in children appears to be uncommon, and when it occurs, it is usually mild. **The 4th version of Belgian guidance for COVID 19 is published on19th March 2020. It is one of the most precise guidelines published yet. Some points from that: 1. Chloroquine is found to have good efficacy in vitro and it reduces the duration of viral shedding. But the drug has a narrow therapeutic window and cardiac toxicity is the most limiting side effect. 2. Hydroxychloroquine is more potent and is superior to chloroquine according to the very recent Gautret’ study. 3. Azithromycin may have a viral suppressive effect, but this needs to be proved as it was noticed accidentally in 6 patients of Gautret’ study. But I think it is a good choice for coverage of bacterial pneumonia. 4. Lopinavir/Ritonavir recently shown not to provide clinical benefit in hospitalized patients with COVID-19. It may reduce ICU stay if given within 10 days of infection but not beyond. 5. Remdesivir is promising but the studies are ongoing. Also, availability is a key issue. 6. Corticosteroids are not recommended as a systemic adjunctive treatment. 7. Paracetamol is the first-line analgesic and antipyretic over NSAIDs which are used with caution. 8. No need to stop ACEIs/ARBs in non-hospitalized patients. CONSIDER changing ACEIs/ARBs to another equivalent antihypertensive in hospitalized patients. 9. Antiviral therapy is not indicated in all patients with suspected/confirmed COVID19.Dr. Prashant Vedwan123 Likes70 Answers

Treatment for severe acute respiratory distress syndrome from COVID-19 In The Lancet Respiratory Medicine, Kollengode Ramanathan and colleagues provide excellent recommendations for the use of extracorporeal membrane oxygenation (ECMO) for patients with respiratory failure from acute respiratory distress syndrome (ARDS) secondary to coronavirus disease 2019 (COVID-19). The authors describe pragmatic approaches to the challenges of delivering ECMO to patients with COVID-19, including training health-care personnel, resolving equipment and facilities issues, implementing systems for infection control and personal protection, providing overall support for health-care staff, and mitigating ethical issues. For patients with COVID-19 who require endotracheal intubation, use of low tidal volume (6 mL/kg per predicted bodyweight) with a plateau airway pressure of less than 30 cm H2O, and increasing the respiratory rate to 35 breaths per min as needed, is the mainstay of lung-protective ventilation. If the hypoxaemia progresses to a PaO2:FiO2 ratio of less than 100–150 mm Hg, there are several therapeutic options. The level of positive end-expiratory pressure can be increased by 2–3 cm H2O every 15–30 min to improve oxygen saturation to 88–90%, with the goal of maintaining a plateau airway pressure of less than 30 cm H2O. Lower driving pressures (plateau airway pressure minus positive end-expiratory pressure) with a target of 13–15 cm H2O can also be used.
