ABSTRACT
Objective To formulate standardized program of gastric lavage for acute organophosphorus pesticide poisoning(AOPP) and evaluate the effects.Methods Evidence was obtained via evidence-based approach,and recommendations were formed.The standardized program of gastric lavage for AOPP was formulated and then applied to clinical practice.The effects were evaluated by examining indicators of success rate of catheterization,the first time of gastric lavage,the time of atropinization and total usage of atropine,ChE recovery time,hospital stay,rebound rate,adverse event rate.Results After implementation,the first time of gastric lavage,the time of atropinization,total usage of atropine,ChE recovery time,and hospital stay were significantly lower than the control group (P＜0.05).Conclusion Evidence-based practice of gastric lavage for AOPP can improve therapeutic effects,reduce adverse reactions,improve quality of nursing,and promote safety of medical care.
