2 Ms. Sedentary  Your patient is a 63 y/o woman who needs an elective subtotal colectomy.  She has multiple lesions in right, left, and transverse colon but no invasion on biopsies.  You agree that it is not urgent, and it would be wise to optimize her health status.

3 History  What co-morbid conditions affect surgical risk?  Which can be altered if we are willing to delay surgery a few months?

4 Risk Factors that Might be Changed  Malnutrition: Decreases wound healing, increases infectious complications  Chronic obstructive lung disease: Pulmonary complications  Current Smoking: Wound complications.  Hyperglycemia: Sepsis and mortality in ICU’s  Coronary Artery Disease: Cardiac morbidity

5 Risk Factors I: Ms. Sedentary  Malnutrition not present: Ms. Sedentary has an albumin of 4.5 and pre-albumin of 30; she is obese.  Chronic obstructive lung disease: She has a ‘smoker’s cough’ productive of colored sputum.  Smoking status: Ms. Sedentary smokes about 1 ppd, down from a peak of > 2 ppd.

6 Risk Factors II: Ms. Sedentary  Hyperglycemia: Ms. Sedentary is an obese diabetic, on two oral medications, with a hemoglobin A 1C of 7.8%.  Coronary Artery Disease: Ms. Sedentary is hypertensive. She does not have angina, but her ability to exercise is limited by claudication.

7 Physical Exam What would you look for?

8 Physical Exam  BMI 32  Diminished pedal pulses  Harsh upper airway noises; clear with cough  Afebrile, BP 154/88, HR 84 and regular with no murmurs or gallops

9 What should be done about smoking?

10  Early papers suggested recent cessation worse than no cessation.  Recent studies: Lower wound and pulmonary complications if cessation for > 3-4 weeks.  Elective cosmetic surgery probably not indicated in current smokers due to doubling wound healing complication rates.  Close follow-up and bupropion both helpful.

11 What about ‘smoker’s cough’?  Rule out pneumonia  Treat active bronchitis with antibiotics.  Treat bronchospasm with bronchodilators.  Add steroids if needed for persistent bronchospasm.

12 What about a cardiac workup?

13  Good studies of non-cardiac surgery in patients with peripheral vascular disease suggest invasive testing not indicated in the absence of symptoms.  However, beta blockade IS indicated perioperatively.  Titrate to HR < 70 as long as BP is not hypotensive.

14 Who qualifies for beta-blockade?  Two or more of the following risk factors: Age > 65 Hypertension Current smoker Hypercholesterolemia Diabetes

15 Pre-Operative Course: You successfully treat her bronchitis, begin bronchodilators, and help her to quit smoking pre-operatively. You also place her on atenolol, and maintain a heart rate less than 70 peri-operatively. What should you do Next ? What should you do Next ?

16 What might you order for Pre- admission testing?

17 CBC:CEA Electrolytes:ABG LFT’s:Lipid Panel Amylase/Lipase:Cardiac Enzymes PT/PTT:Other: U/A: Possible Labs

18 Studies ?

19 Possible Studies Chest X-RayEKG Pulmonary Function Testing Echocardiogram Other:Stress Test

20 Is Ms. Sedentary a candidate for any pre-op prophylaxis?

21 Pre-op prophylaxis  Bowel Prep ?  DVT ?  Antibiotic ?

24 What should you do about her diabetes postoperatively?

25 What is your target Blood Sugar range?

26 ICU Studies  Normoglycemia: Less mortality, less sepsis  Insulin administration: No protective effect per se.

27 Sliding Scale vs. Insulin drip  Sliding scales generally allow more time spent in higher (> 200) ranges.  Insulin drip potentially more dangerous outside of ICU’s because staffing may be low and checks for hypoglycemia infrequent.  Blood sugars above range interfere with white blood cell function, affecting wound healing and resistance to infection.
