Abstract
To compare the effects between concentrated-dose and non-concentrated-dose pralidoxime chloride on respiratory muscle paralysis(RMP) in acute organophosphorus pesticide poisoning(AOPP). 76 cases of RMP due to AOPP were involved in a retrospective study. All the patients were poisoned through ingestion. According to the administered dose of pralidoxime chloride within the first three days after the onset, the patients were divided into two groups: Group A consisted 30 patients; they were given pralidoxime chloride 10.0-25.8 grams (with an average of 11.4 grams) everyday in the first three days after the onset. Group B included 46 patients; the dose of pralidoxime chloride used daily in the first three days ranged from 3.3 to 8.6 grams (average 6.3). The curative rate and the death rate in group A were 73.3% and 26.7% respectively, while those in group B were 21.7% and 78.3% respectively. The curative rate in group A was significantly higher than that in group B (chi 2 = 19.83, P < 0.005). Concentrated-dose pralidoxime chloride was more effective than non-concentrated-dose for patients with RMP due to AOPP and this kind of administration could remarkably improve the prognosis in such patients.
