Effects of shock
-
-
Prolonged hypotension which can lead to life threatening organ failure after recovery from the acute event
Hypovolaemic shock
Loss of blood due to - acute GI bleeding, trauma, peri/post-operative, splenic rupture
Loss of fluid - dehydration, burns, pancreatitis
-
Septic shock
-
Septic shock exists when sepsis is complicated by persistent hypotension that is unresponsive to fluid resuscitation
-
-
Treatment
ABC
B - breathing (give 100% O2) and correct immediately life threatening problems e.g. congestive heart failure, bronchospasm & tension pneumothorax
C - circulation
- Establish secure IV access
- Give fluid quickly and blood if acute blood loss
- Ensure haemostats i.e. stop bleeding
-
Acute circulatory failure with inadequate or inappropriately distributed tissue perfusion for aerobic cellular respiration, resulting in generalised hypoxia and/or an inability of the cells to utilise oxygen
