Postoperative Analgesia

Brief summary

The patients were randomly allocated into 3 parallel groups of 20 patients in each group by using computer generated tables. group(Q):received bilateral sonar-guided quadratus lumborum bolck using 20 ml bupivacaine 0.25%on each side.group(E): received bilateral ultrasound-guided erector spinae block using 20 ml bupivaciane 0.25%on each side. group(C):didn't received any block

Detailed description

on arrival to the operative room all patients were monitored with standared monitoring. then IV cannula were inserted. preoxygenation with 100% oxygen and induction of GA by 1mic/kg fentanyl and 2 mg/kg of 1%propofol. endotracheal intubation was facilitated by 0.5mg/kg of atracurium. isoflurane 1-2% with oxygen was used for anesthetic maintenance and 0.15 mg/kg intermittent doses of atracurium to maintain adequate muscle relaxation. ventilation was controlled to maintain end tidal CO2 at 35-40 mmHg and SaO2 between 95-100. after stabilization of the patient's hemodynamics and before surgical incision, quadratus lumborum and erector Spinae block were performed according to patient's group by the same anesthetist with the patient in lateral or prone position respectively.

Interventions

PROCEDUREnerve block

bilateral ultrasound-guided posterior quadratus lumborum block was done in the lateral decubitus and linear or curvilinear probe was used according to the depth and placed in the midaxillary line in the transverse plane above the iliac crest
