Brief Summary

Our aim was to investigate the effect of quadro iliac plane block on postoperative analgesia in patients undergoing percutaneous nephrolithotomy surgery and to determine which areas of the skin this block anesthetizes.

Conditions

Postoperative Pain; Percutaneous Nephrolithotomy

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: OTHER
• Blinding Strategy: QUADRUPLE

Study Groups

Control group

No non-routine procedures will be performed on this group.

Group Type: NO_INTERVENTION

No interventions assigned to this group

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.
