I am due to have a TLIF fusion Jan 27th.. I have a severe DDD at l5-s1.. I am concerned with the post-op pain in recovery and after in general.. I havent met with my anestisiologist yet but worried because I am opiate tolerant and not sure how to ask for meds for post-op recovery and while on the PCA.. I have had morphine after surgery b4 and dilaudid also.. The dilaudid worked alot better with the pain than the Morphine.. They were giving me Fentanyl in recovery and it suxed for me.. I know they usually use morphine in the PCA at a 6-10 min lockout and 10mg per hour.. Not sure about dilaudid but assume it would be 1/10 of that because of its strength.. Has anyone had similar surgery and what was used in recovery to control the pain? What was used in the PCA pump? I know after home the oral meds will be Percocet 10/325 and zanaflex.. The hospital is my concern the 3-5 days i will be there.. Thank U!!!!
