Brief Summary

The current investigation aimed to assess the postoperative analgesic efficacy of quadratus lumborum block against erector spinae plane block in sleeve gastrectomy surgeries

Conditions

Quadratus Lumborum Block; Erector Spinae Plane Block; Sleeve Gastrectomy

Outcome Measures

Primary Outcomes (1)

• the initial request for analgesia post-surgery

  analgesia request willbe assessed by Pain intensity was measured using the Visual Analogue Scale (VAS) score, the scale from 0 to 10 and 10 is the worst pain

  24 hours

Quadratus lumborum Block Group

ACTIVE COMPARATOR

The patient was in the lateral position, and the US probe was placed in the anterior axillary line to visualize the typical triple abdominal layers. Then, the probe was placed in the midaxillary line, and at this juncture, the layers of abdominal layers started to taper. When the probe was placed in the posterior axillary line as per the posterior approach, sonoanatomy showed first the transversus abdominis disappearing, then the internal oblique and external oblique forming aponeurosis, and the appearance of the QL muscle was noticed. The posterior aspect of the QL muscle was confirmed, and a 22-G block needle was guided, in plane, and the needle tip was inserted into this aspect of the QL muscle. Following aspiration, the local anesthetic was injected into the lift behind the QL muscle. The same procedure was performed bilaterally

Procedure: Technique of erector spinae plane block:

Erector spinae plane block Group

ACTIVE COMPARATOR

The patient will be placed in a sitting position. Under aseptic conditions, a high-frequency linear transducer will be placed on the spinous process at the T8 level on the parasagittal plane and then slide 2.5-3 cm laterally to visualize the transverse process and erector spinae muscle. Using the in-plane technique, the needle was advanced between the transverse process and erector spinae muscle. The correct location was confirmed, and local anesthetic was injected between the muscle and transverse process. The same procedure was performed bilaterally

Procedure: Technique of posterior quadratus lumborum block (QL 2 block):
