Summary

Percutaneous nephrostomy (PCN) is one of the interventions in the radiology department in which pain control is necessary. Quadratus Lumborum (QL) block will be tried to limit the use of systemic analgesics and its accompanying untoward effects in those frail patients requiring PCN that is performed in the prone position.

Detailed description

Quadratus Lumborum block is a novel technique in which extension into the thoracic paravertebral space may occur. QL block would seem to be able to alleviate both somatic and visceral pain so it's expected to decrease the need for systemic sedation\\analgesia to a minimum.

Conditions

• Nephrostomy; Complications
• Upper Urinary Tract Dilatation and Obstruction
• Regional Anesthesia Morbidity
• Adverse Anesthesia Outcome

Interventions

Type	Name	Description
PROCEDURE	Local Anesthetic infiltration	Lignocaine infiltration through the nephrostomy track
PROCEDURE	Quadratus Lumborum block	A linear 12-MHz ultrasound probe will be placed in the anterior axillary line to visualize the typical triple abdominal layers. Then, the probe will be placed in the midaxillary line and at this point the layers of abdominal layers starte to taper. The probe will be placed in the posterior axillary line, sonoanatomy will show first the transversus abdominis disappearing then the internal oblique and external oblique forming aponeurosis and appearance of QL will be noticed. At the posterior border of the quadratus lumborum muscle and outside the fascia, Touhe needle will be inserted in plane and confirmed its position by injecting saline. Under ultrasound (US) guidance, local anesthetic mixure will be deposited separating the fascia
DRUG	MAC	Incremental doses are given to the targed sedation and analgesia
