Fibrinolytic therapy in patients with COVID-19 and ARDS: protocol for a systematic review and meta-analysis

Abstract

Introduction In COVID-19-related acute respiratory distress syndrome (ARDS), the clot play a role in gas exchange abnormalities. Fibrinolytic therapy can improve alveolar ventilation by restoring blood flow. In this systematic review and meta-analysis protocol, we aim to assess the safety and efficacy of fibrinolytic therapy in such a population. Methods We will perform a systematic search in MEDLINE, EMBASE, Cochrane CENTRAL and LILACS databases without language restrictions for relevant randomised controlled trials (RCTs) and quasi-RCTs. Two review authors will independently perform data extraction and quality assessments of data from included studies. In case of divergence, a third author will be contacted. The Cochrane handbook will be used for guidance. If the results are not appropriate for a meta-analysis, a descriptive analysis will be performed. Discussion This systematic review and meta-analysis protocol will provide current evidence about the safety and efficacy of fibrinolytic therapy in patients with COVID-19 and ARDS. These findings will provide if fibrinolytic therapy might be an option for a desperate clinical setting, where all medical efforts have been used.
