Ultrasound Guided Psoas Compartment Block vs Suprainguinal Fascia Iliaca Compartment Block

Ultrasound Guided Psoas Compartment Block vs Suprainguinal Fascia Iliaca Compartment Block for Pain Management in Pediatric Patients With Developmental Dysplasia Sia of the Hip Joint, Randomized Controlled Trial

The aim of this study was to compare the intraoperative and the postoperative analgesic effect of psoas compartment block (PCB) and supra-inguinal fascia iliaca compartment block (SFIB) in pediatric patients undergoing developmental dysplasia of the hip

All subjects after entering operation room will be connected to standard monitor electrocardiograph, non-invasive blood pressure, heart rate, oxygen saturation. Three mg/kg of propofol, 0.2 μg/kg of fentanyl and 0.1 mg/kg midazolam will be used for sedation. Oxygen at the concentration of 100% will be administrated under the mask in all patients after satisfactory sedation, tracheal intubation will be performed after intravenous anesthesia with administration of 3 mg/kg of propofol, 0.6 μg/kg of fentanyl and 0.9 mg/kg of rocurium. After intubation 2-3% of sevoflurane and 0.2-0.3 mcg/kg/min of fentanyl will be used to maintain anesthesia guided by PSI and hemodynamic monitoring. The two groups will receive nerve block with local anesthetics. In the SFIB group, the patients will receive ultrasound-guided SFIB, while the patients in the PCB group will receive PCB under the guidance of ultrasound. Local anesthetic 0.25% Ropivacaine will be used at 1 ml/kg for SFIB and PCB. (the dose of local anesthetic for SFIB or PCB was not more than 35ml). All blocks will be performed by the same experienced anesthesiologist.

After induction of anesthesia; ultrasound guided psoas compartment block will be done using ropivacaine 0.25% 1ml/kg.

After induction of anesthesia; ultrasound guided suprainguinal fascia iliaca compartment block will be done using ropivacaine 0.25% 1ml/kg.

0.25% Ropivacaine will be used at 1 ml/kg will be injected Ultrasound guided after induction of general anesthesia.

Intraoperative anesthetic requirement including intraoperative sevoflurane concentration and total fentanyl consumption

Inclusion Criteria: Patients undergoing undergo acetabuloplasty Anesthesiologists (ASA) physical status of I to II Exclusion Criteria: Known allergy to local anesthetic Infection at the block site.
