Fascia Iliaca Compartment Block and IPACK Block in Total Knee Arthroplasty

The investigators sought to compare the effectiveness of postoperative pain control between the standard intravenous multimodal analgesia procedure used in managing patients undergoing total knee surgery, who experience severe postoperative analgesia needs, and multimodal analgesia procedures that incorporate ultrasound-guided peripheral nerve blocks (Fascia Iliaca Compartment Block or iPACK Block) during postoperative follow-up. The aim is to determine which procedure is more effective.

About this study

All patients who received a total knee replacement surgery conducted by orthopaedic surgeons at the operating theatre of Health Sciences University Ankara Atatürk Sanatorium Training and Research Hospital and underwent postoperative pain assessment by anaesthetists will be retrospectively reviewed as part of the study.

Postoperative pain management follow-up for patients who have undergone surgical procedures at Anaesthesiology and Reanimation Clinic is standard practice during patients hospitalization. Patients who have undergone painful and significant surgical procedures are typically given postoperative patient-controlled analgesia devices and are administered intravenous painkillers that are under the patient's control. As part of multimodal analgesia procedure, the investigators apply peripheral nerve blocks routinely to eligible patients, provided that the necessary criteria are met. Once the postoperative Anesthesiology and Reanimation clinic's follow-up form, the regional anaesthesia follow-up form, is completed, patients receive coordinated follow-up care from anaesthesiologists and surgical physicians in postoperative ward to monitor analgesic requirements and increase patient satisfaction. Hourly monitoring ensures that patients receive optimal care.

The aims of study to examine the effectiveness of these procedures. The investigators will include all patients who received elective total knee arthroplasty surgery in the operating room of Ankara Atatürk Sanatorium Training and Research Hospital within the past year (between 01 March 2022 and 31 March 2023) in retrospective file review and postoperative pain follow-up study.

Treatment and study plan

no peripheral block

Procedure

No peripheral block was applied. Standard multimodal analgesia method was applied.

Fascia iliaca compartment block

Procedure

Fascia Iliaca Compartment Block is performed with the patient in a supine position. A high-frequency (6-14 MHz) linear ultrasound probe is positioned transversely to locate the femoral artery in the inguinal crease. The hyperechoic femoral nerve is usually visualized lateral to the femoral artery, between the iliopsoas and fascia iliaca. The probe is manoeuvred in a cranial and caudal direction to capture high-quality images of the femoral nerve and fascia iliaca. Identification of the triangular-shaped sartorius muscle and anterior superior iliac spine (ASIS) is achieved by lateral movement of the probe. Post-skin disinfection, the needle tip is directed just beneath the fascia iliaca. Local anaesthetic is administered following negative pressure aspiration into the area. The local anaesthetic spreads towards the femoral nerve medially and towards the iliac process laterally.

IPACK block

Procedure

During the iPACK procedure, the patient assumes a supine position with the lower extremity flexed at the knee and abducted at the hip (in frog-leg position). The ultrasound transducer is placed in the lower third of the medial thigh, and then pushed backward and downward to visualize the gap between the popliteal artery and the femoral shaft, straight above the femoral condyles. After ensuring that the needle tip is placed 2 cm beyond the lateral border of the artery, local anaesthetic solution is administrated in divided doses to infiltrate the tissue space. The needle is then withdrawn after confirming negative aspiration.

Primary outcomes

  1. Numerical Rating Scale (NRS)

    Time frame: postoperative 24 hours score change

    NRS was used to assess postoperative pain. The NRS is a segmented numerical version of the visual analog scale (VAS), in which the respondent chooses an integer (0-10 integer) that best reflects the intensity of his pain. It is considered a one-dimensional measure of pain intensity in adults. It is an 11-point numerical scale. It ranges from "0" representing no pain to "10" representing extreme pain.

Secondary outcomes

  1. 5-point likert satisfaction scale

    Time frame: postoperative 24th hour

    The patient's satisfaction with postoperative pain treatment will be recorded. 5 options; very dissatisfied, dissatisfied, neither dissatisfied or satisfied, satisfied, very satisfied
