If a patient cannot feel a pulse in their leg after surgery, what could be a possible sign of complications?

• A. Increased mobility in the limb
• B. Brownish discoloration of the skin
• C. Itchy sensation in the calf
• D. Coldness of the affected leg

Answer: (D)

In the context of post-surgical assessment, the absence of a pulse in the leg can indicate compromised blood flow, potentially due to complications such as arterial occlusion. Coldness of the affected leg serves as a crucial sign of this impaired perfusion. When blood flow is inadequate, the leg may lose warmth as it is no longer receiving the necessary blood supply, which is typically warm due to the presence of oxygen-rich blood. This coldness is often accompanied by other signs of ischemia, such as pallor or impaired sensation. Recognizing this symptom allows for prompt evaluation and intervention, which is essential to prevent serious complications like tissue necrosis. In contrast, increased mobility, brownish discoloration, and an itchy sensation do not directly indicate an immediate vascular issue following surgery. While these can represent various post-operative concerns, they are less indicative of the critical emergency situation suggested by a non-pulsatile limb.
