Abstract & Overview
The study's objective was to describe the effect of using high doses of N-acetylcysteine on severe COVID-19 patients. It was evaluated from the length of stay and by monitoring the drug use data, laboratory data, and clinical data at Bhayangkara H.S Samsoeri Mertojoso Hospital Surabaya. The data was collected retrospectively from patients' Health Medical Records who got high dose N-acetylcysteine in October 2020 – February 2021, with standard therapy: antivirus (Remdesivir), antibiotics, vitamins, symptomatic and comorbid therapy, anticoagulant, and corticosteroids (Dexamethasone) as inclusion criteria, then described descriptively. The observation result confirmed that the use of a high dose of N-acetylcysteine (NAC) [1 x 1200 – 5000 mg] po/iv had effective results as seen from the patients' length of stay, which was 12 days for patients without comorbid and 14 days for patients with comorbid like diabetes and/or hypertension. The use of high dose NAC showed improvement in the patients' clinical condition that is evaluated from improved oxygen saturation by 37%. In addition, the laboratory results are shown an improvement in thorax X-ray by 69% and inflammatory markers like CRP and d-dimer by 100%. Further research that uses a prospective method is needed to get a better result on the use of high-dose NAC in patients with severe COVID-19.
