Initial Hemopurification Strategy for Acute Paraquat Poisoning in Adults

Overview

HeSAPP is a single-center, non-blinded, parallel-group randomized controlled trial studying the hemopurification strategy for acute paraquat(PQ) poisoned patients. The intervention to be investigated include hemodialysis (HD), hemoperfusion (HP), combined hemoperfusion-hemodialysis concurrent therapy (HP-HD) and conservative therapy. The object of the present trial is to investigate whether hemopurification therapy can reduce mortality compared with conservative therapy.

Patients diagnosed with acute paraquat poisoning in the Emergency Room of the First Affiliated Hospital of Zhengzhou University would be stratified according to their urine dithionite test results and randomly assigned to four different groups: HD, HP, HP-HD and control (conservative therapy) group for different treatment. Arterial blood gas test, complete blood count, coagulation function, liver function, pancreatic function, urine dithionite test, renal function and chest radiographs would be closely monitored during treatment. Primary endpoint is 28-day mortality. Secondary endpoints include (1) survival time (from the time of PQ ingestion to the time of death), all-cause mortality at the 3rd, 7th and 60th day; (2) rate of necessary oxygen uptake and rate of mechanical ventilation; (3) in-hospital length of stay and ICU length of stay; (4) APACHE II score and PSS score; (5) rate of general complications, such as respiratory failure, acute kidney injury (AKI), acute liver failure, pancreas function abnormality and Multiple Organ Failure (MOF); (6) rate of intervention related complications, such as catheter placement related complications, thrombocytopenia and deep venous thrombosis; (7) rate of adverse events, which include unexpected death, severe hemorrhage or edema, unplanned extubation, coagulation in the extracorporeal circulation, blockage of cartridge, incorrect pipe connection, etc.
