PATOFISIOLOGI TRAUMAPATOFISIOLOGI TRAUMA
Definisi :
TRAUMA adalah semua jenis kekerasan yang menimpatubuh sehingga terjadi kerusakan/gangguan pada strukturdan fungsi jaringan/organ tubuh yang terkena, bahkansecara sistemik dapat berdampak pada aspek fisiologis,kejiwaan dan kondisi sosial insan yang bersangkutan.

SIRS can be identified by the presence of two or more ofthe following manifestations :
1. A body temperature greater than 38C or less than 36C.2. Heart rate greater than 90 beats per minute3. Tachypnea (respiratory rate > 20 breaths per minute or
Pa CO2 < 32 mmHg4. White blood cell count greater than 12.0 x 109/L or less than
4.0 x 109/L or the presence of more than 10% immatureneutrophils (bands).

SIRS and MODSSIRS and MODS
Inflammatory and organ dysfunction responses to injury. Normal response to an injury or insult may decrease after 3 to 5 days or be reactivated by a
complication. A continuous inflammatory response is seen with systemic inflammatory response syndrome (SIRS) and can eventually progress to organ
dysfunction (reprinted from 4).
