TKR: surgicalcharacteristics • Surgicalriskmoderate • Surgical duration 60 – 240 minutes !!! • Bleeding • intraoperative + • Postoperative +++ • Postoperative painrelated to flessum
Anesthetic technique ? • GA ? Why not? • Preoperativeepidural or femoralcatheter • Spinal anesthesia • Combined Spinal-epidural • Femoralcatheter • Nerve blocks • Psoas block (catheter) + sciatic block • Intraoperativesedation or TIVA
Prevention of Spinal anesthesia- induced hypotension in the elderlyBuggy D, A&A 1997
Mortality / Morbidity: RA – GA : No difference • Operating time • Mortality • Cardiovascularmorbidity • DVT / Pulmonaryembolism • Intra-operativebloodloss
Bleedingafter major orthopedicsurgeryGA = Reg Anesth % major bleeding
TKR: tourniquet or not ? • Anyeffect on bleeding?NO • Hersekli MA, IntOrthop. 2004 • Schuh A, ZentralblChir. 2003 • Tetro AM, Can J Surg. 2001 • Jorn LP, ActaOrthop Scand. 1999 • Anyeffect on venousthrombosis? • Wauke K, Arch Orthop Trauma Surg. 2002 Yes • Harvey EJ, J Arthroplasty. 1997No
Why Regional Analgesia ? • Superior to iv PCA (opioids) • Excellent “dynamic analgesia”… 72h • Avoids opioid-side effects • nausea-vomiting +++ • sedation
Total knee replacement • Epidural analgesia ? • Psoas, femoral block, iliofascial block ? • Is an obturator nerve block reallyuseful ? • Sciatic block ? • Single shot or catheter? • Infiltration ?
Peripheral nerve catheters > Epidural • Efficacy: PNB Epid • Side effects: PNB <Epid • Major Complications: PNB < Epid * Epidural abcess* Epidural hematoma
Watson M.W, RAPM 2005 Spinal anesthesia Sciatic 15 ml levoB Psoas Catheter: - bolus 25 ml levoB - perfusion * placebo * L-Bupi PCA iv (morphine) Is a femoral catheter really indicated ?
Is the catheterreallynecessary ? • Prolongedanalgesia • similar 3 monthsoutcome FunctionalOutcome Resting and Peak VAS Pain Systemicanalgesicrequirement
Sciatic nerve block for total-knee replacement: isitreallynecessary in all patients ? Levesque S, DelbosA, RAPM 2005 • Predictive risk factors of pain 1- Flessum 2- important preoperative pain 200 TKR patients N= 25 (12.5%) needed a single sciatic block in PACU
Pham Dang C, RAPM 2005 • PCA Morphine (mg) 23 mg vs 4 mg* • Vomiting 43% vs 14%* Is the femoralcatheterenough or is a sciatic block necessary ?
What about 0,3mg spinal morphine ? • Effective • Adverse effects: PONV– Pruritus
Total knee replacementis the femoral catheter enough ? • (D0- D1): pain anterior & posterior ! • The catheter is not enough • - Sciatic block (Allen, Weber, Mansour) • - morphine: iv PCA, spinal, s/cut … • (D2- D4): physiotherapy …. • the femoral catheter is sufficient
Total knee replacment …Regional analgesia >> PCA morphine • Quality of analgesia • Quality of early physiotherapy: KINETEC • Discharge criteria: Knee Flexion at 90 • Duration of physiotherapy +++ • PCA 50 days • Epidural 37 days • PNB 40 days
Femoral Nerve Block ImprovesAnalgesiaOutcomesafter Total KneeArthroplastyA Meta-analysis of RandomizedControlledTrials(JE Paul, Anesthesiology 2010) • Single shot FNB >> iv PCA till 48h • Compared to a single shot FNB: • Addition of Sciatic block no benefit • Femoralcatheterno benefit

Total knee replacement Regional Analgesia > PCA morphine But … The final functional result of the operated knee is not related to any analgesia technique or drug … Colwell 1992, Munin JAMA 1998

INFILTRATION : EFFECTIVE EVIDENCE INFILTRATION VS OPIODS Better analgesia Less consumption of opiods

Total Knee Replacement The Past ... The Present ... And the Future ! • Anesthesia GA = Spinal = Blocks • PostoperativeRegionalAnalgesia • Femoral block is the standard today • Femoralcatheter … longer analgesia • Obturator block … weakinterest • Sciatic block … for the first 24h • LIA … promising but requireslargersurveys
