  1. Open Pelvic Fracture Intern 蕭福慶

  2. Brief History • 42 y/o female, denied systemic disease • Pedestrian hit by car on 94.12.9 • Lower limbs numbness, back pain • Open pelvic fracture, bilateral scapular fracture • Operation in 和平 Hospital

  3. Event 1 • X-ray: L’t pelvic fracture • Spine CT: no obvious abnormality • 12.11: hypotension, tachycardia • 12.12: fecal material in drain • Abd CT: gas at rectal wall • Laparotomy with sigmoid and colostomy

  4. Question 1 • Does rectal injury have correlation with open pelvic fracture?

  5. Open Pelvic Fracture • A direct communication between a skin, rectal, or vaginal wound and the fracture • Motality: 5% to 50% (25~30%)

  6. The American Journal of Surgery 190 (2005) 833

  7. Risk • Incidence of anorectal injury: 18~64% • Incidence of urogenital injury: 23~53% • Rectal injury: pubic symphysis, SI joint • Bladder injury: SI joint, pubic symphysis, fractures of the sacrum • Urethral injury: superior, inferior pubic rami, pubic symphysis

  8. Examination • Anteroposterior pelvic X-ray • Inspection of the perianal tissues • Digital rectal examination • Sigmodoiscopy or proctoscopy, • Pelvic CT: localised extraluminal gas haemorrhage bowel wall thickening

  9. Treatment • Pelvic fracture stabilization • Wound debridement • Selective diverting colostomy • Colostomy takedown (6weeks~3months)

  10. Brief History • 12.12: Shock, dopamin was used (hypotension, respiratory failure, elevated liver function, oliguria, pancytopenia, limbs discoloration) • Doppler: no flow at bilateral dorsa pedis, medial, lateral malleolus arteries in ankles • 12.17: tentative fasciotomy

  11. Event 2 • 94.12.22: CVS: PGE1, pletaal NS: suspect T8 injury • 12.23: Wound: Proteus mirabilis, Klebsiella pneumoniae, Pseudomonas aeruginosa • 12.27: Left AK amputation • 95.1.2: Right AK amputation

  12. Question 2 • Why does her four limbs have gangrene change?

  13. Symmetrical Peripheral Gangrene • Symmetrical distal ischemic damage in two or more sites • Absence of large vessel obstruction • Rare(?) • Motality: up to 40% with DIC • Amputation: 50% • Ischemia of other organ (gut)

  14. Mechanism • Vasospasm • Pathology in microcirculation • Slugging of platelet or fibrin degeneration product

  15. Risk • Disseminated intravascular coagulation • Sepsis (Streptococcus, Staphylococcus) • Vasopressor • Malignant disease(paraneoplastic syndrome) • Ergotism • Protein C deficiency • Cold injury • Scleroderma, polymyalgia rheumatica • Impaired renal function • Splenectomy • Diabetes mellitus • Immunosuppression • Alcoholism

  16. Course • Marked coldness, pallor, cyanosis or pain in the extremity • Progress rapidly to acrocyanosis • Gangrene

  17. Treatment • Control underlying problem (DIC, sepsis, vasopressor) • Local or intravenous infusion of an α-blocker (phentolamine, chlorpromazine) • Intravenous infusion of prostaglandin (epoprostenol) • Sympathetic blockade (ganglion block or intravenous trimethaphan therapy) • Intravenous nitropruside therapy • Topical nitroglycerine ointment • Amputation (usually not emergency)

  18. Brief History • 12.12: Shock: oliguria • 12.14~: H/D • BUN/Cre: 127.6/5.6 • U/O: 250-300ml • Bilateral pleural effusion, pitting edema

  19. Event 3 • 12.27: Left AK amputation • Contrast CT was need to evaluate the situation of infection (possible abscess)

  20. Question 3 • Can we perform contrast CT on the patient with acute renal failure?

  21. Contrast-induced Nephropathy • Within 48 hours after administration of contrast media. • Increased Serum creatinine > 44μmol/L (0.5 mg/dl) • Relative increase of at least 25% • Oliguria 2~5 days, recover on Day 7

  22. Mechanism • Renal hemodynamic change: • medullar hypoxia • Direct toxic effect: • tubular epithelial cell • Osmolality: • compress intrarenal microcirculation • decreased glomerular filtration rate

  23. Prevention • Hydration (U/O>150 mL/hr for the first 6 hours after the procedure) • IOCM, iso-osmolar contrast medium(Iodixanol) • Low contrast volume (<100 mL, Spacing at least 10 days) • N-acetylcysteine(NAC)(600 mg, by mouth, twice a day (two dosages before and two doses after contrast exposure)) • Hemofiltration for critical ill or ICU

  24. Treatment • Supportive management • Hemodialysis (eGFR<15)

  25. Take home message 1 • Open pelvic fracture: • High motality • Stabilize hemodynamics • Complete examination(rectal, vaginal, wound) • Colostomy, debridement

  26. Take home message 2 • Symmetrical peripheral gangrene • Early notice of ischemic sign • Beware of multiple organ ischemia • Control DIC, sepsis • Decrease the use of vasopressor as possible • Amputation rate: 50%

  27. Take home message 3 • Contrast-induced nephropathy • Evaluate risk • Alternative examination • Hydration if could tolerate • Low contrast volume • N-Acetylcysteine • Hemofiltration in critical ill
