Abstract
Abstract
Background
Acute severe organophosphorus pesticide poisoning is a common severe emergency in developing countries. Our meta-analysis aimed to clarify the efficacy of hemoperfusion combined with hemodialysis on acute severe organophosphorus pesticide poisoning.
Methods
Several databases were searched. After formulating relevant inclusion and exclusion criteria, qualified studies were included, and the data were extracted. The outcome indicators were the success rate of rescue, the time of hospitalization, the incidence of complications, the time for the cholinesterase level to return to normal, the coma time, and the atropine dosage. The results were analyzed using risk ratios, weighted mean difference, standard mean difference, and 95% confidence interval. The Cochrane Collaboration tool was used to assess the risk of bias in all the included studies. In terms of statistical methods, we used RevMan software (version 5.3; The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark) and Stata (versions 14 and 16; StataCorp, College Station, TX, USA) for the data analysis.
Results
We included 92 randomized controlled trials with 6899 participants. Compared with the conventional emergency treatment group (CET group), the hemoperfusion group (HP + CET group), and the hemodialysis group (HD + CET group), the use of hemoperfusion combined with hemodialysis based on CET (HP + HD + CET group) significantly increased the success rate of rescue and reduced hospitalization time, the incidence of complications, time for cholinesterase level to return to normal, coma time, and atropine dosage.
Conclusion
Hemoperfusion combined with hemodialysis is effective in the treatment of acute severe organophosphorus pesticide poisoning. In the future, more scientifically designed, large-scale, high-quality, multicenter randomized controlled trials are needed to validate this study further.
