During the first five days of hospitalization, 58 children died such that most of them were hypomagnesaemia. About 39.6% of 101 children who consumed diuretic medicine were hypomagnesemia. This pattern was 43.8% and 40.00% from 130 and 85 patients who used digital or aminoglycoside medicines. About half children who had heart diseases were hypomagnesemia. These trends were 33.3% in kidney and sepsis; about 50.00% and 43.5% were hypomagnesaemia from those had a central nervous disorder and respiratory respectively.
