Abstract
SUMMARY
The present work was designed to study the correlation
between methanol level and osmolal gap; and the utility of the later
as an early detection procedure for methyl alcohol toxicity.
This study was conducted as following, 30 patients of acutely
methyl alcohol intoxication are chosen from the Emergency Room
of Poison Control Center of Ain Shams University Hospital with
another 10 normal persons as a control group. The following
parameters were done on both groups:
Measured osmolality, Blood urea nitrogen(BUN),
Serum glucose and serum sodium for Calculated
osmolality. So, osmolal J:!!J!c.an be obtained from the
difference between measured and calculated
osmolality. Also we measured Anion t:!Y!J.pH,
Ethanol blood level and methanol blood level.
We found that there is a highly significant correlation between
methanol blood level and osmolal gap among all patients studied as
r = 0.59605.
Also, a significant correlation between methanol blood level
and calculated osmolality among all patients studied as r = 0.47191.
A highly significant correlation between methanol and
measured osmolality among all patients studied as r = 0.79479.
A significant correlation between methanol and anion gap
among all patients studied as r = 0.33834.
A significant correlation between methanol and pH among all
patients studied as r = -0.54672.
On the other hand there is no correlation between all the
parameters and ethanol blood level which means that the changes in
these parameters were due to the increase of methanol blood level
with comparison with control group.
