Gender and status asthmaticus.
BACKGROUND
Adult women may be more susceptible to asthma than men.


OBJECTIVE
Women are more likely to develop status asthmaticus (SA) requiring critical care.


METHODS
The medical records of patients admitted to our medical intensive care unit (ICU) for SA between 1994 and 2000 were examined. A number of demographic and physiologic variables were extracted from the medical records.


RESULTS
Of 103 total admissions, 53 (of 37 patients) were age < 50 years and had clinical evidence suggesting SA. Among these 37 patients, the average (+/-SE) age was 30.8 +/- 1.0 y with average acute physiology and chronic health evaluation (APACHE) II of 9.5 +/- 0.8. Seventeen patients were Hispanic, 13 were black, and 7 were white. Twenty-four patients (accounting for 37 admissions) were female and 13 patients (16 admissions) were male. Although women accounted for a greater absolute number of endotracheal intubations (ETI; 17 vs. 12) and were more likely to be admitted to ICU more than once (7 vs. 3), men had a higher incidence of ETI (RR=1.6; 95%CI=1.04-2.6). The need for using therapeutic permissive hypercapnia and lengths of stay (ventilator, ICU, and hospital) were similar between men and women. Two patients, both women, died of causes not related to treatment of SA.


CONCLUSIONS
These data suggest that although women accounted for more ICU admissions for SA, men were more likely to require ETI.
