Scorpion venom is a potent stimulator of the autonomic
nervous system causing a sudden outpouring of endogenous
catecholamines into the circulation. This leads to transient
sympathetic stimulation manifested by vomiting, sweating,
bradycardia, priapism, salivation and hypotension. Later
sustained parasympathetic stimulation is followed with
hypertension, tachycardia, and myocardial failure.
Pulmonary edema is the most serious complication of
scorpion envenomation and is the usual cause of death in this
syndrome. It has been attributed to acute left ventricular failure
and increased pulmonary vascular permeability induced by
vasoactive substances released upon the venom sting.
The aim of this work was to assess the possible role of
some laboratory parameters such as plasma proteins,
hemoglobin concentration, total leukocytic count and platelet
count in early diagnosis of pulmonary edema secondary to
scorpion envenomation among patients.
This study was done during the period from January 2008
to September 2008.The total number of scorpion sting cases
received by the Poison Control Center (PCC) was 193 cases.
Out of these 193 cases, 19 patients of both sexes were admitted
to the Poison Control Center (PCC) and all of them were
enrolled in this study. All these patients had manifestations of

scorpion envenomation.In addition ten healthy individuals were
used as negative controls.
These patients were classified according to the presence
of pulmonary edema into two groups; patients without
pulmonary edema (group II) and patients with pulmonary
edema (group III).The healthy individuals served as controls
(group I).
The results were tabulated and statistically analyzed and
revealed that:
Age
The mean age in the current study was 21.15±13.98 in
group II and 16.40±11.22 in group III, ranging from11m to 48
years.
Gender
Males represented the majority of cases (63.2%) while
females represented (36.8%).In group II ,males were (57.1%)
and females were (42.9%) while in group III they were (80%)
and (20%) respectively.
Residence
The majority of cases (63.2%) came from Mansheyt Naser
followed by El fayoum (15.8%), Giza (10.5%) and the least
number of cases came from Ismailia and Monoufya
(5.25%each).
