Pre-Surgery Optimization Protocol

Pre-operative optimization reduces complications, speeds recovery, improves outcomes. Modifiable risk factors: Smoking is #1 - impairs wound healing (vasoconstriction, reduced oxygen delivery), increases infection risk 2-6x, respiratory complications. Quit minimum 4-6 weeks before (ideally 8+). Even 4 weeks helps. Glucose: Diabetics with A1C >7% have dramatically increased infection risk, wound complications. Tight control 4+ weeks pre-op essential. Even non-diabetics benefit from avoiding hyperglycemia. Malnutrition: Protein-calorie malnutrition (albumin <3.5) increases complications 3-6x. High-protein diet, adequate calories 2-4 weeks before. Vitamin D: Deficiency (<20 ng/ml) increases post-op infection risk (innate immune function depends on vitamin D). Load to 40-60+ ng/ml. Vitamin C: Essential for collagen synthesis (wound healing). Zinc: Wound healing, immune function (deficiency impairs both). Vitamin A: Epithelialization, immune function. Probiotics: Reduce post-op infection risk (strengthen gut barrier, immune function). Especially important for GI surgeries. Discontinue bleeding-risk supplements: Fish oil, vitamin E, ginkgo, garlic, ginger, curcumin 1-2 weeks before (increase bleeding). Omega-3 <1g likely safe, higher dose stop. Carbohydrate loading: ERAS (Enhanced Recovery After Surgery) protocols use pre-op carb drinks (night before, 2 hours before) - reduces post-op insulin resistance, nausea, hunger. Outdated "NPO after midnight" causes dehydration and discomfort - clear liquids allowed up to 2 hours before in most protocols now. Prehabilitation: PT/conditioning 4-6 weeks before major surgery improves post-op function (especially joint replacement, abdominal surgery). Mind-body: Visualization, relaxation techniques shown to improve outcomes (less pain, faster healing) - "Prepare for Surgery, Heal Faster" guided imagery program used by many hospitals. Optimize comorbidities: Anemia, uncontrolled hypertension, heart failure, COPD - get as optimized as possible. Elective surgery can be delayed if needed for optimization. Emergency surgery doesn't allow this luxury. Patient activation: Patients who are informed, prepared, and actively involved have better outcomes. Educate, encourage questions, involve in decision-making.
