Surgical Complications John Cosgrove, MD FACS Chairman and Residency Program Director Bronx Lebanon Hospital Center
Primum no nocere • Think before you act.
Complications can be deadly… • Logarithmic increase in bile duct injuries after the introduction of laparoscopic cholecystectomy.
SCIP • Antibiotics • Normothermia • VTE Prophylaxis
Morbidity and Mortality Conference • Mainstay quality program of general surgery residency programs.
Morbidities • Cardiorespiratory • Wound • Urinary tract
Wound • Seroma • Hematoma • Dehiscence • Evisceration
Wound • Superficial • Deep • Organ space
Pathogens • Staphylococcus(coagulase neg) 25% • Enterococcus(D) 11.5% • Staph aureus 8.7% • E. coli 6.5%
Wound classification • Clean • Clean contaminated • Contaminated • Dirty
Temperature regulation • Issues of hypothermia
Malignant hyperthermia • 1 in 30,000 cases • Mortality less than 10% • Autosomal dominant with variable penetrance • Altered calcium metabolism • Halothane, isoflurane, succinylcholine • Cause rise myoplasmic calcium
MH • Tachycardia • Arrhythmia • Raised temperature • Acidosis • Muscle rigidity • Tachypnea • Flushing • (inability to open mouth)
Treatment • Discontinue triggering anesthetic • Hyperventilate with 100% oxygen • Terminate surgery • Dantrolene 2.5mg/kg as bolus and repeat every 5 minutes • Monitoring • Sodium bicarbonate • Beta blockers • Lidocaine • Lasix
Pulmonary complications • Atelectasis • Pneumonia • Pulmonary embolism • Aspiration • Pulmonary edema • ARDS
Weaning criteria • RR <25 breaths/min • Pa02 >70mmHg(Fi02 of 40%) • PaC02<45 mm Hg • MV 8-9L/m • TV 5-6mL/kg • NIF -25cm H20
Cardiac • Greatest risk in first 48 hours • Non-Q wave, non ST segment elevation
Prevention • Major predictors of risk • Unstable chest pain, CHF, sympotomatic arrhythmias, severe valvular disease
Management • Cardiology consult • Tachyarrhythmia • Unstable-cardioversion • SVT-Beta blocker, esmolol, amiodarone • PSVT-vagal stimulation, adenosine, amiodarone • MAT-B blocker or amiodarone • VTach-lidocaine or amiodarone • Brady-atropine • Heart block-high grade second or third degree-insertion of permanent pacemaker
Amiodarone • Phosphodiesterase inhibitor • Inhibits breakdown of camp • Increase cardiac output and decreases preload and after load without increasing myocardial oxygen demand • May cause vasodilitation and GI problems and thrombocytopenia
Adrenal • Chronic use of steroids causes suppression of the HPA axis • Potentially life threatening • Give 250ug cosyntropin intravenousl
Hemodialysis indications • Serum potassium >5.5 • BUN>80-90 • Persistent metabolic acidosis • Acute fluid overload • Uremic symptoms(pericarditis, encephalopathy, anorexia) • Removal of toxins • Platelet dysfunction • Hyperphosphatemia with hypercalcemia
SIADH • Common cause of chronic normovolemic hyponatremia • Serum sodium<135 • Treat underlying disease process • Fluid restriction • Rapid correction may result in seizures
Gastrointestinal • Ileus • Early SBO • Compartment syndrome • GI bleeding • Stomal complications • C. difficile colitis
Anastomotic leak • Strategies for prevention • Low anterior resection
Enterocutaneous fistula • Low output <200 cc/24h • Moderate 200-500 cc/24 h • High >500 cc/24 h
“The Checklist” • Provonost • Gawande
Airline Industry • Crew resource management • Communication • No hierarchy • Checklist, checklist, checklist • Debriefing
Universal Protocol • Preprocedure Verification • Presurgical “timeout” • Post procedure “debriefing”
Prospective Case Conference • Dr. Judson Randolph • 1988-Childrens Hospital Center, Washington, DC • A priori discussion of all upcoming pediatric surgery cases involving multiple disciplines
