USG-Guided Infiltration Popliteal Artery Capsule Knee Block Versus Adductor Canal Block Application as Postoperative Analgesia

In the present study, the purpose was to evaluate the effect of Ultrasound(USG)-guided adductor canal block(ACB) and infiltration popliteal artery capsule knee block(IPACK) combination on postoperative analgesia before total knee arthroplasty(TKA). A total of 40 patients,who were aged 18-75 with the American Society of Anesthesiologists score(ASA) I-III physical status,and who were scheduled for TKA under general anesthesia,were included in the present study.ACB and IPACK were performed in group A(ACB+IPACK) accompanied by USG, Bupivacaine and 10 mL of 0.9% sodium chloride were applied in each block application.No block was applied to the patients in group B.Patient-controlled analgesia was administered to both groups 30 minutes before the end of the surgery.Tramadol HCL was infused at a concentration of 4mg/ml.A bolus of 20 mg of tramadol hydrochloride was given with a lock-in interval of 30 minutes.Postoperative systolic arterial pressure(SAP),diastolic arterial pressure(DAP),mean arterial pressure(MAP),heart rate(HR),visual analog scale(VAS),analgesic consumption,nausea,vomiting, and patient satisfaction scores were recorded.
