Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Participants Caregivers Investigators

The patient will not know which study group he is in. The anesthetist, who will perform the regional block, will give the block to be applied in a sealed envelope by an assistant staff outside the study, and at the same time, the patient will not know which block has been made. The anesthesiologist who made the block will not participate in the pain follow-up of the patients. Postoperative pain assessment and data collection will be performed by another investigator blinded to the study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group SFI (Suprainguinal fascia iliaca block)

In the patient lying in the supine position, a high-frequency linear probe is inserted under sterile conditions, using an in-plane technique, 1 cm cephalad of the inguinal ligament with an 85 mm needle. Using hydro-dissection, the fascia iliaca is separated from the iliac muscle and a space is created where the needle can be advanced cranially, and the procedure will be completed by injecting local anesthetic into this space.

When the patient whose block procedure is successful, is taken to the recovery room, controlled analgesia will be applied to the patient and he will be transferred to the ward. Tramadol HCL will be used for postoperative pain control for PCA.
