To evaluate the effectiveness of Adductor Canal Block and combined Adductor Canal plus IPACK block in reducing postoperative pain and analgesic requirements in patients undergoing knee surgery.
In total knee arthroplasty, ultrasound-guided Adductor canal block or Adductor Canal block combined with local anesthetic infiltration between the popliteal artery and the capsule of the knee (IPACK) will provide adequate postoperative analgesia.
Study Type
OBSERVATIONAL
Enrollment
60
All patients in Group I will receive a preoperative adductor canal block. In all groups, an intravenous patient-controlled analgesia device containing morphine will be administered for postoperative pain management.

RECRUITINGopioid consumption
In the recovery room, all patients will given a patient- controlled analgesia device containing morphine 0.5 mg/ml, set to deliver a 1mg bolus dose of morphine with an 15 min lockout time and 4 mg 1 h limit.Total morphine consumption during the 24 hours postoperative period will recorded at 5 times intervals ( 2, 4, 6, 12, 24 hours).
Time frame: 24 hours after surgery
Verbal analog Pain Scores on rest and movement
A Research assistant, blinded to the group allocation, interviewed patients and collected data at 5 times intervals ( 2, 4, 6, 12, 24, hours) in the 24 hours postoperatively. Patients were asked to rate their pain using verbal analog scale, where 0= no pain and 10= worst pain possible.
Time frame: 24 hours after surgery
incidences of adverse effects (like nausea and vomiting)
incidences of nausea and vomiting during the 24 hours postoperative period will recorded at 6 time intervals ( 2, 4, 6, 12, 24 hours).
Time frame: 24 hours after surgery
