Evaluation of Postoperative Analgesic Efficacy of Suprainguinal Fascia Iliaca Block
Condition: Regional Anesthesia
Study type: Interventional

Summary: 
      It was aimed to evaluate the postoperative analgesic efficacy of the suprainguinal fascia
      iliaca block applied in the postoperative period in terms of 24-hour opioid consumption, pain
      score, additional analgesic need, and side effects and complications in the postoperative
      period, and to see the postoperative analgesic effectiveness of this block in patients who
      underwent knee arthroplasty.
    

Detailed description: 
      Total knee arthroplasty (TKA) is one of the major orthopedic surgeries that cause severe
      postoperative pain. A successful post-operative outcome is possible with strong and effective
      pain control followed by early mobilization and a good functional recovery.

      There are many studies in the literature showing successful results regarding the
      effectiveness of suprainguinal fascia iliaca block on postoperative pain in pain control
      after hip surgery. However, there is not enough information about the use of suprainguinal
      fascia iliaca block in knee arthroplasty. With this study, the investigators aim to
      contribute to the literature on the use and effectiveness of suprainguinal fascia iliaca
      block in knee arthroplasty.

      An identification number (ID) number will be randomly assigned to each participants, whose
      written consent was obtained before the surgery, when they are admitted to the postoperative
      recovery room. In the postoperative period, participans will be followed up with these
      numbers in patient follow-up. Which group the participants will be included in will be
      determined by the closed envelope method.

      Participants who underwent unilateral knee arthroplasty will be included in the prospective
      and randomized study. The participants will be divided into two groups and suprainguinal
      fascia iliaca block and patient-controlled analgesia (Group SFI) will be applied to one group
      and patient-controlled analgesia (Group PCA) will be applied to the other group.

      No block attempt will be made to the participants in the patient-controlled analgesia group
      (Group PCA), and when the patient is taken to the recovery room after surgery,
      patient-controlled analgesia will be administered and transferred to the ward.

      Group SFI; the block procedure will be applied to the participant lying in the supine
      position under sterile conditions with a high-frequency linear probe (ESAOTE Fixed Color
      Doppler Ultrasonography Device, Italy).In the block method, 0.25% bupivacaine (Buvasin Vem
      İlaç, Turkey) (15 ml physiological saline + 15 ml 0.5% bupivacaine) total amount of 30 ml,
      same volume and same concentration will be used. The participant with the block will be
      followed in the recovery room and if the block is successful, PCA treatment will be started
      and the participant will be taken to the ward.

      Evaluation of postoperative pain will be done with numerical rating scale (NRS).Pain levels
      will be questioned in two different ways as rest and passive moving.
