Brief summary
The purpose of this study is to compare the analgesic effectiveness of three techniques: the femoral nerve block, intraarticular infiltration or a combination of both in the control of pain in total knee arthroplasty (KA). The hypothesis to be tested in this study is that the performance multimodal postoperative pain KA combining two analgesic techniques to obtain better analgesia than when applied separately.
Interventions
DRUGseveral drugs: morphine chloride,ropivacaine,epinephrine,ketorolac
This technique is performed intraoperatively with a 100 ml solution containing: 225 mg of ropivacaine 1% (22.5 ml) + 5 mg of morphine chloride 0.1% (5ml) + 30 mg of epinephrine 1:1000 (0.3 ml ) + ketorolac 30mg (1ml) +71 ml of 0.9% saline
DRUGropivacaine,morphine chloride,epinephrine,ketorolac
This technique is performed intraoperatively with a 100 ml solution containing: 225 mg of ropivacaine 1% (22.5 ml) + 5 mg of morphine chloride 0.1% (5ml) + 30 mg of epinephrine 1:1000 (0.3 ml ) + ketorolac 30mg (1ml) +71 ml of 0.9% saline
DRUGropivacaine
The lock is held before starting the operation, viewing with ultrasound and confirmed the femoral nerve with nerve stimulation at an intensity of 0.5 mA and a frequency of 2 Hz Pajunk 50mm needle, patellar flexion. It be administered 30ml of ropivacaine 0.75% (225mg)
DRUGmorphine ,ketorolac
ultrasound-assisted femoral nerve block is performed and leaks intraoperatively with a 100 ml solution containing: 5 mg of morphine to 0.1% (5ml) +30 mg of ketorolac (1 ml) +96 ml of 0.9% saline.
