The aim of this retrospective descriptive study was to describe both epidemiologically and clinically manifestations following severe scorpion envenomation and to define simple predictive factors which can be used in routine practice in general Intensive Care Units (ICU) as an indicator of poor prognosis. Cases were collected from hospital patients' files during 13-year (1990-2002) period in the medical Intensive Care Unit of a university hospital (Sfax - Tunisia). The diagnosis of scorpion envenomation was based on a history of scorpion sting. Nine hundred fifty-one patients, who were admitted for a scorpion sting, were analyzed. There were 769 patients (80.8%) in the grade III group (with cardiogenic shock and/or pulmonary edema or severe neurological manifestation (coma and/or convulsion)) and 182 patients (19.2%) in the grade II group (with systemic manifestations). Scorpion envenomation is more frequent in summer; indeed 82.3% of our patients were admitted between June and September. The mean age (+/-SD) was 14.7 +/- 17.4 years, ranging from 0.5 to 90 years. In this study 739 patients (77.8%) had neuromuscular signs, 700 patients (73.6%) had gastrointestinal signs and 585 patients (61.5%) had a pulmonary edema, while 195 patients (20.5%) had a cardiogenic shock. The mean blood sugar on admission was at 11.32 +/- 5.66 mmol/l, a high blood sugar level (>11 mmol/l) was observed in 39% of cases. The mean blood urea was at 7.1 +/- 3.2 mmol/l, it was above 10 mmol/l in 10.7% of cases. The mean of leucocytes was at 17 418 +/- 7833 cells/mm(3), it was above 11 000/mm(3) in 80% of cases. In the end of the stay in ICU, evolution was marked by the improvement of 879 patients (92.5%) while 72 patients (7.5%) died. A multivariate analysis found the following factors to be correlated with a poor outcome: age less than 5 years (OR = 2.27), fever >38.5 degrees C (OR = 2.79), coma with Glasgow coma score < or =8/15 (OR = 9.87), pulmonary edema (OR = 8.46), leucocytes >25 000 cells/mm3 (OR = 2.35) and blood urea >8 mmol/l (OR = 4.02). Moreover, in children group, a significant association was found between PRISM score and mortality rate, this model had a high discriminative power with an area under the ROC curve at 0.93. In the adult patients a significant association was found between SAPS II score and mortality rate, this model had a high discriminative power with an area under the ROC curve at 0.82. In summary, in severe scorpion envenomation, age less than 5 years, fever >38.5 degrees C, coma with Glasgow coma score < or =8/15, pulmonary edema, leucocytes >25 000 cells/mm3 and blood urea >8 mmol/l were associated with a poor outcome.

This study aimed to identify the clinical and laboratory manifestations that affect outcome of scorpion envenomation in children. It included 154 children admitted with scorpion sting envenomation over a period of 2 years. The epidemiological, clinical, and laboratory findings of patients were recorded, and grading of severity was performed based on local and systemic involvement. Organ failure was determined according to diagnostic criterion of multiple organ dysfunction syndrome, and severity of illness was assessed by the Pediatric Risk of Mortality (PRISM III) score. Of studied children, 58.4% were males and 41.6% were females. Children aged > 5 years suffered more scorpion stings (79.9%) than others did. The place of residence was rural more than urban, outdoor stings more than indoors, nocturnal more than diurnal, and most stings were on the exposed areas of the limbs. Based on clinical evaluation, 37.7% of patients were classified as class I severity followed by class II (48.7%) and class III (13.6%). Among studied cases, 21 deaths (13.6%) were registered; all of them belonged to class III severity. Mortality was significantly higher in children with agitation, coma, convulsions, arrhythmia, heart failure, pulmonary edema, and priapism. There were significantly higher values of leukocytes, platelets, creatinine, liver enzymes, glucose, and creatine phosphokinase in non-survivors than in survivors. The presence of organ failure was associated with mortality. In addition, the need for mechanical ventilation and inotropic support were at increased risk of mortality. Moreover, a significant association was found between PRISM score and the number of failed organs with fatal outcome.
