– Discussion: – pathophysiology: – compartment syndrome is elevation of interstitial pressure in closed fascial compartment that results in microvascular compromise; – as duration & magnitude of interstitial pressure increase, myoneural function is impaired & necrosis of soft tissues eventually develops; – intracompartmental pressure: … Read more
– Discussion: – many surgeon use 30 mm Hg as the cut off for performing fasciotomy; – diastolic pressure: (Whiteside’ Theory): – development of a compartment syndrome depends not only on intra-compartment pressure but also depends on systemic blood pressure; – DBP – CP should be greater than 30 – references: – Diastolic … Read more
