RESUMEN
OBJECTIVE: To observe the curative efficacy of rhubarb, montmorillonite powder combined with blood purification on treatment for patients with severe acute organophosphorus pesticide poisoning (AOPP). METHODS: 39 patients with AOPP were divided into treatment group (received the combined treatment of rhubarb, montmorillonite powder and blood purification on the basis of routine therapy, n = 21) and control group (only received the routine treatment because of financial difficulties or the will of family members, n = 18). The differences of clinical manifestations, curative effects and prognosis between two groups were compared. RESULTS: The time of consciousness recovery, the duration of mechanical ventilation and the length of stay in hospital in treatment group were (6.5 ± 1.3), (7.9 ± 2.0) and (13.1 ± 3.2) days, which were significantly shorter than those [(8.4 ± 2.4), (10.7 ± 2.9) and (16.5 ± 3.7) days] of control group (P < 0.05). In 5, 6 and 7 day after treatment,the cholinesterase (ChE) activities of treatment group were significantly higher than those of control group (P < 0.05). The total amount and using time of atropine and pyraloxime methylchloride in treatment group were significantly smaller and shorter than those in control group (P < 0.05). The death rate of treatment group was [19.0% (4/21)], which were significantly lower than that of control group [19.0% (4/21)] (P < 0.05). CONCLUSION: The combined treatment of rhubarb, montmorillonite powder and blood purification of the AOPP patients has a better curative effect.
