Comparison of QIPB and SIFICB in Hip Surgery

Comparison of the Effects of Quadroiliac Plane Block Versus Suprainguinal Fascia Iliaca Compartment Block on Postoperative Pain in Hip Surgery

The aim is to compare the postoperative analgesic effects of Quadroiliac Plane Block (QIPB) and Suprainguinal Fascia Iliaca Compartment Block (SIFICB) in patients undergoing hip surgery.

Study Overview

• Status: Not yet recruiting
• Conditions: Postoperative Pain; Hip Surgery
• Intervention / Treatment: Procedure: Quadro-İliac Plane Block(QİPB); Procedure: Suprainguinal Fascia Iliaca Compartiment Block

Detailed Description

Patients were divided into two randomized groups: Group 1 (QIPB group, n=30) and Group 2 (SIFICB group, n=30). All patients will receive the same standard general anesthesia per hospital protocol. All blocks will be applied with the same ultrasonography and block equipment, and by the same physician. After the anesthesia induction, patients in Group 1 will receive Quadroiliac Plane Block (QIPB) with 40 mL of 0.25% bupivacaine. Patients in Group 2 will receive Suprainguinal Fascia Iliaca Compartment Block (SIFICB) with 30 mL of 0.25% bupivacaine. All patients will receive Paracetamol 1gr and Dexketoprofen 50mg intravenous (IV) 10 minutes prior to skin closure. Routine analgesic procedure consisting of 3x400mg Ibuprofen will be followed postoperatively for 24 hours. Numeric Rating Scale (NRS) will be used to assess postoperative pain on 1st, 6th, 12th, 18th and 24th hours after the surgery. Tramadol 1mg/kg IV will be administered as a rescue analgesic for all patients if NRS score is higher than 4. Total Tramadol consumption will be calculated.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Quadro-İliac Plane Block(QİPB); For this group, after the surgical procedure is completed, the patient will be placed in a lateral position with the operated side facing up, and a QIPB will be performed. With the patient in the lateral position, the spinous process of the L3 vertebra will first be imaged with an ultrasound probe positioned transversely in the midline. Then, by slightly shifting the probe laterally, the transverse process of the vertebra will be visualized within the erector spinae muscle. The probe will then be rotated in the sagittal plane and advanced caudally about 1 cm, visualizing the crista iliaca. On the cranial side of the crista iliaca, the erector spinae muscle, quadratus lumborum, and psoas major muscles will be visualized sequentially. With the needle direction cranial to caudal, the crista iliaca will be gently touched, and the needle will be positioned between the erector spinae and the quadratus lumborum muscle. After injecting 40 ml of 0.25% bupivacaine, the needle will be injected.	Procedure: Quadro-İliac Plane Block(QİPB); 40 mL of 0.25% bupivacaine
Active Comparator: Suprainguinal Fascia Iliaca Compartiment Block (SIFICB); Probe Placement: A high-frequency linear ultrasound probe is placed in a sagittal orientation over the Anterior Superior Iliac Spine (ASIS) and then moved medially. Anatomical Landmark: The key visual target on the ultrasound screen is the "bowtie" sign, which is formed by the junction of the sartorius and internal oblique muscles over the iliacus muscle.Injection Point: The target for injection is the potential space located directly beneath the fascia iliaca (seen as a bright, hyperechoic line) and superficial to the iliacus muscle.Needle Insertion: The block needle is advanced using an "in-plane" technique (parallel to the probe's long axis), typically from a caudal-to-cranial direction (from bottom to top).Injection: After confirming correct needle tip placement with hydrodissection (visualizing fluid separating the fascia from the muscle), 30-40 mL of local anesthetic is slowly injected. The spread of the anesthetic proximally (upward) beneath the fascia is monitored in real-time	Procedure: Suprainguinal Fascia Iliaca Compartiment Block; 30 mL of 0.25% bupivacaine

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Numeric Rating Scale (NRS) Scores	Numerical rating scale is used for pain assessment. The scores of the numerical rating scale changes between 0 to 10 points. 10 points mean "the most severe pain that the patient ever had". 0 point means "there is no pain." Higher scores mean worse outcome.	Postoperative 24 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Total tramadol consumption	Postoperative total analgesic need was recorded as "milligram" in unit.	Postoperative 24 hours
