As a CA1 & 2, our TKA protocol was a femoral nerve catheter, spinal with morphine, postop PCA, monitored bed overnight (fear of PCA + intrathecal morphine). Carrying the pain service pager on call was torture. We were always getting called on them. Every time that pager went off an hour of my life was lost.
Around the beginning of my CA3 year, the TKA protocol changed to
- preop scopalamine patch
- preop Celebrex 200
- preop Neurontin 600
- preop Tylenol 1000
- femoral nerve catheter preop bolus of ~20 cc 0.5% ropiv
- spinal with morphine
- postop PCA (but rarely used by patient)
- PCA dc'd POD1, percocet started
- CFNC ran 0.2% ropiv until removal on AM of POD2
Difference was night and day ... can count on one hand the number of pain calls I got to postop TKAs while a CA3.
