Efficacy of magnesium sulphate in aluminium phosphide poisoning--comparison of two different dose schedules.
The results of an open randomised study on the efficacy of magnesium sulphate therapy in aluminium phosphide poisoning are presented. One hundred and fifty five patients divided in three groups and matched for age, sex, dose, duration and severity of poisoning constituted the subject matter. Significant hypomagnesemia was observed in patients who did not receive magnesium sulphate (group 1). Two dose schedules of MgSO4 therapy were tried. The dose schedule No.1 given to patients of group 2 did not raise the magnesium levels significantly as compared to controls (group 4). The difference in the mortality between groups 1 & 2 was also not significant. On the other hand, the dose schedule No.2 given to patients of group 3 raised the magnesium levels significantly and these remained above normal limits throughout the observed period. This dose schedule brought down the mortality significantly than dose schedule No.1 (p < 0.001). It was also found that dose schedule No.2 has been effective in reducing the mortality irrespective of dose of pesticide consumed and its efficacy was due to rapid rise in magnesium levels. It is suggested that hypomagnesemia might be responsible for high mortality of patients of aluminium phosphide poisoning and its correction has beneficial effect on the management and ultimate favourable outcome of the illness.
