POSTOPERATIVE MANAGEMENT OF ORTHOPEDIC PATIENTS

1. POSTOPERATIVE MANAGEMENT OF ORTHOPEDIC PATIENTS THE SURGEONS PERSPECTIVE ED SZALAPSKI JR., M.D. TWIN CITIES ORTHOEDICS

2. PHYSIOLOGIC RESPONSE TO TRAUMA • VASODILATION • INCREASED MEMBRANE PERMEABILITY • THIRD SPACING • FLUID RETENTION

3. RESULT • PATIENTS REQUIRE VOLUME SUPPORT • LOW BP • LOW URINE OUTPUT • ORGAN DAMAGE • RENAL FAILURE

4. MODIFIERS • GENERAL HEALTH • MEDICATIONS • LOCATION OF SURGERY • MAGNITUDE OF DISSECTION • OUR INTERVENTIONS

5. RECOVERY • AS PATIENTS RECOVER, THEY MOBILIZE/REABSORB FLUIDS • INCREASED URINE OUTPUT • OCCASIONAL FLUID OVERLOAD

6. PRIMARY HIP REPLACEMENT CMS CHECKS BLOOD LOSS URINE OUTPUT/RENAL FUNCTION BLOOD PRESSURE (HTN MEDS!) DISLOCATIONS

7. PRIMARY KNEE REPLACEMENT • PAIN MANAGEMENT!!!!! • BLOOD LOSS (250 TO 1250 ml) • URINE OUTPUT/RENAL FUNCTION • MOTION • VITAL SIGNS (HTN MEDS)

8. PATELLA FRACTURE • MINIMAL DISSECTION • MINIMAL BLOOD LOSS • STRAIGHTFORWARD PAIN MANAGEMENT • MINIMAL THIRD SPACING • NON-WEIGHT BEARING • PATIENT STRENGTH & MOBILITY FACTORS

9. TIB FIB FRACTURE • BLOOD LOSS IS USUALLY MILD • THIRD SPACING IS USUALLY MILD • PAIN MANAGEMENT • COMPARTMENT SYNDROME!!!!

10. COMPARTMENT SYNDROME PRESSURE WITHIN THE FASCIAL COMPARTMENT RISES ABOVE PRESSURE WITHIN THE SMALL VESSELS ISCHEMIA RAPID ONSET OF PERMANENT DAMAGE TO MUSCLE AND NERVES

11. COMPARTMENT SYNDROME • PAIN, PAIN, PAIN • LOSS OF ACTIVE MOTION • PAIN WITH PASSIVE MOTION • LOSS OF PULSE IS TOO LATE • LOSS OF PERFUSION IS TOO LATE • BEDSIDE PRESSURE MEASUREMENT • SURGICAL EMERGENCY

12. INTERTROCHANTERIC HIP FRACTURE • BLOOD LOSS DEPENDS ON DISPLACEMENT AND COMMINUTION • BLOOD LOSS IS HIDDEN IN THIGH MUSCLES, NOT IN THE DRAIN, IF ANY • WATCH THE URINE OUTPUT • WATCH THE VITALS

13. PERIPROSTHETIC FRACTURE • MODERATE BLEEDING AND THIRD SPACING • LOW CMS RISK • NON WEIGHT BEARING • MOTION • MODERATE PAIN

14. PERIPROSTHETIC FRACTURE • EXTENSIVE DISSECTION • MAJOR BLOOD LOSS AND THIRD SPACING • GREAT DEAL OF DRAINAGE • WATCH URINE OUTPUT • THIRD SPACING

15. SEPTIC TOTAL KNEE • 84 YO MALE • DIABETIC • HTN • VENOUS STASIS • SEVERAL WEEKS OF DENIAL

16. REIMPLANTATION • QUADRICEPS TURNDOWN—RESTRICTED MOTION AND WEIGHT BEARING • THREE UNITS OF BLOOD • MILD ACUTE RENAL FAILURE • MILD CHF SEVERAL DAYS LATER

17. SEPTIC TOTAL HIP • 60 YO MALE • PRIOR IM NAIL • 300+ POUNDS • MRSA INFECTION • VANCOMYCIN ALLERGY • THREE DEBRIDEMENTS TO ERADICATE INFECTION

18. HIP REIMPLANTATION • 8 UNITS PRBC • 10 LITERS OF FLUID • PRESSORS FOR 12 HOURS • MILD RISE IN Creatinine—resolved • FULL WEIGHT BEARING

19. SUMMARY • IT’S NOT JUST THE BONES • THINK ABOUT GENERAL PHYSIOLOGY OF SURGERY
