Common post operative problems and complications
Post operative fever may indicate what?
Atelectasis UTI Wound infection Pneumonia Sepsis
low grade fever may be normal tissue trauma of surgery
Physiological cause of most post-op CV and pulmonary complications
acidosis, hypoxemia, and/or hypercarbia
volume disorders
Common GI complications post surgery
N/V - narcotics
Gastroparesis
GI bleed or stress ulcers
C. diff
How is MET’S significant in pre-operative eval?
Measure of energy expenditure
1 MET = sitting watching tv
4 MET = going up 1 flight of stairs
anything less than 4 increases post-op risk; asses CV and pulm more closely
What to ask for in history in pre-operative eval?
angina, prior MI CHF HTN valvular d/o rhythm d/o Recent URI Asthma/COPD Renal impairment prolonged bleeding, coagulopathies h/o TIA or stroke h/o anesthesia problems smoke? obese?
effects of over-sedation during surgery
atelectasis
Indications for antibiotic prophylaxis pre-surgery?
Valvular heart disease
Prosthetics (ex. total hip)
Certain procedures (ex. colon resection, knee arthroscopy)
Prophylaxis for pulmonary embolism post-surgery?
Get patients out of bed and moving
Mini-heparin; Lovenox
Pneumatic sequential stockings; ted hose for those at risk (hip surgery, Virchow’s triad)
Ulcer prophylaxis for ICU patients
PPI’s
H2 blockers/ antacid
Why do a preoperative eval?
decrease incidence of operative or post complications
Post-operative N/V (PONV) risk factors
female young motion sickness nonsmoker prior PONV
Prophylaxis for post-operative N/V
5HT-3 inhibitors
Scopalamine
Dexatmethosone
Metoclopromide
American Society of Anesthesiologists (ASA) classification of surgery patients
I: Normally healthy pt
II: Mild/controlled systemic dz
III: Non-incapacitating severe systemic dz
IV: incapacitating / threat to life systemic dz
V: Moribund pt not expected to survive 24 hrs w/ or w/o operation (basically dead)
Why listen for carotid bruit in pre-op eval?
assess stroke risk
Treatment of malignant hyperthermia during surgery
IV Dantrium
Reasons for hypoxia in preoperative state
Over sedation
Atelectasis (and eventually pneumonia)
Aspirate
