In Uruguay, cases of whopping cough have raised since 2011. Objective: to describe clinical features of children with whopping cough hospitalized in the Intensive Care Unit (ICU) of Centro Hospitalario Pereira Rossell. Methodology: a descriptive study was done between 1st April to 31th December of 2011. Chidren with whopping cough were included. Clinical and laboratory features were registred from clinical records.

In 9 cases a fatal evolution was observed. 10 children developed Pulmonary Hypertension, 7 of these children died. White blood cells (WBC) count at admission was higher in chidren with a letal evolution (72.300 WBC/mm3 versus 34.537 WBC/mm3). Velocity of rising of WBC was higher in those who died (2.305 WBC/hour) than in survivors (495 WBC/hour)(p<0.0001).
