Question

patient's with an immediately threatened extremity (severe pain, delayed capillary refill, absent Doppler signals, and sensory or motor deficits) are at risk for irreversible myonecrosis within 4-6 hours and should have ___ and ___

Answer 1

Patients with signs of an acutely threatened extremity should undergo immediate surgical evaluation and revascularization to prevent irreversible myonecrosis.

Step-by-step explanation:

Patients with an immediately threatened extremity, characterized by severe pain, delayed capillary refill, absent Doppler signals, and sensory or motor deficits are at high risk for irreversible myonecrosis and should have prompt surgical evaluation and revascularization.

The goal is to restore circulation and prevent further tissue death. The urgency is due to the narrow window before significant muscle damage occurs, typically within 4-6 hours. An immediate surgical consultation is vital, and revascularization procedures such as embolectomy or bypass surgery may be necessary to save the limb and the patient's life.

An immediately threatened extremity (severe pain, delayed capillary refill, absent Doppler signals, and sensory or motor deficits) are at risk for irreversible myonecrosis within 4-6 hours and should have emergency surgical intervention and revascularization procedures.
