A prospective pilot study examining nutritional supplements among vascular surgery patients
with Critical Limb Ischemia (CLI). CLI patients have a high rate of malnutrition and has the
potential to benefit greatly from nutritional intervention. The investigators plan to
evaluate nutrition and functional status of patients by assessing objective lab values and
the use of the hand grip strength test. Providing perioperative nutritional supplements to
patients has potentially improved their nutritional status, which in turn may improve the
patient's clinical status after surgery.
