The authors performed this study in all patients or or = 45 percent) 62 (57.9 percent), cells platelets decreased 50.000/mm3 at the shock in 57 (53.3 percent). factors related to shock is also fever ongoing shock, in early shock (the third day, the fouth day), rising Hematocrite (hematocrit or = 45 percent) at the start of the shock. the authors also found a negative correlation between blood concentrations increased and decreased platelet cells, between blood concentration and systolic blood pressure at the shock. the authors recommend that the relevant factors should be closely monitored in in shock patients infected with DHF and timely intervention to reduce mortality.
