Director of AIIMS, Dr Randeep Guleria has said that CT scans and biomarkers are being misused and they can be harmful as well. Briefing media in New Delhi, Dr Guleria said, there is no use of a CT scan if a person have mild Covid. He said, data by the International Atomic Energy Agency for radiation protection and medicine have shown an increased risk of cancer in later life due to frequent CT scans, especially if done at a young age.
Dr Guleria said, one CT scan is equivalent to almost 300 to 400 chest x-rays and it increases the risk of getting cancer in young people. He said, even in mild illness and according to a study, even in asymptomatic cases, a CT scan may show patches which go away on their own without treatment.
The AIIMS Director said, clinical management guidelines are clear that people with mild illness need no medicine. He advised that based on limited data, one can take ivermectin or hydroxychloroquine but there is no need to take too many medicines. Dr Guleria said, some patients take steroids in the early part of the disease which increases viral replication and taking high dose steroids in mild cases may lead to severe viral pneumonia. He said, steroids should be taken in moderate stage and as advised by doctors.
Dr Guleria said, falling oxygen saturation, excessive fatigue are warning signs that indicate Covid patient in home isolation needs hospitalisation. He said, in moderate illnesses three types of treatment, oxygen therapy, steroids and anticoagulants are effective and are the main treatment strategy.
