Nutritional status and wound healing in lower extremity amputations

Area of Science:

• Surgical outcomes
• Nutritional science
• Lower extremity amputations

Background:

• Nutritional status significantly impacts patient recovery.
• Assessing nutritional markers like serum albumin and lymphocyte counts is vital.
• Lower extremity amputations require careful preoperative evaluation.

Purpose of the Study:

• To investigate the association between nutritional status and postoperative complications in patients undergoing lower extremity amputations.
• To determine if nutritional status affects the healing of amputations proximal to the Symes level.

Main Methods:

• Prospective study of 41 patients with lower extremity amputations.
• Nutritional status assessed using serum albumin and total lymphocyte counts.
• Complication rates compared between nourished and malnourished patient groups.

Main Results:

• 15 of 16 nourished patients healed uneventfully.
• 11 of 25 malnourished patients experienced postoperative complications.
• The difference in complication rates was statistically significant (p < 0.05).

Conclusions:

• Malnutrition adversely affects healing and prognosis for lower extremity amputations.
• Nutritional screening upon admission is recommended for amputation patients.
• Postponing elective surgery for malnourished patients or providing perioperative nutritional support is advised.
