Erector Spinae Plane Block in Pediatric Lower Limb Surgery

Impact of Ultrasound Guided Erector Spine Plane & Caudal Block For Postoperative Analgesia In Pediatric Lower Limb Surgeries

Anesthesia will be induced in all patients using Fentanyl 1µg,propofol 2mg/kg and cisatracurium 0.15 mg/kg IV to facilitate endotracheal intubation, maintenance of anaesthesia afterward will be achieved by isoflurane1.5-2% in oxygen and air mixture, cisatracurium0.03 mg/kg.

In both groups , ultrasound guided block will be performed by an experienced anesthesiologist who has no subsequent role in the study after induction of anesthesia and before starting of surgery in lateral position, sterilized and covered with sterile sheets. Aseptic precautions is taken by wearing sterile gowns and gloves A sterile preparation of the ultrasound probe is obligatory. Outcome parameters will be assessed by another anesthesiologist blinded to the groups of assignment.

Study Overview

• Status: Completed
• Conditions: Efficacy of Erector Spinae Plane Block in Lower Limb Surgery in Pediatric
• Intervention / Treatment: Procedure: erector spinae plane block; Procedure: ultrasound guided caudal block

Detailed Description

Ethical considerations:

• After approval from institutional ethics committee, an informed consent will be obtained from all parents of participants in this research. All data of patients will be confidential with secret codes and private file for each patient, and all given data will be used for the current medical research only.
• Any unexpected risks appear during the course of the research will be cleared to the participants and ethical committee on time and proper measures will be taken to overcome or minimize these risks Patients will be randomized into two equal groups at a ratio of 1:1 to receive either Erector spine plane block (Group I n= 25) or Caudal block (Group II n= 25).

Randomization will be performed using sealed opaque envelopes indicating the group of assignment. A blinded nurse, who will not participate in the study or data collection, read the number contained in the envelope and made group assignments.

A preoperative evaluation in form of history taking, clinical examination and routine laboratory investigations, On arrival to the operating room, an intravenous (IV) cannula 24-22 gauge will be inserted and standard monitoring in terms of electrocardiogram (ECG), non-invasive blood pressure, capnograph and pulse oximeter for oxygen saturation (SpO2) will be connected to each participants. Patient received ,05mg midazolam and 4 mg ondansetron.

Anesthesia will be induced in all patients using Fentanyl 1µg,propofol 2mg/kg and cisatracurium 0.15 mg/kg IV to facilitate endotracheal intubation, maintenance of anaesthesia afterward will be achieved by isoflurane1.5-2% in oxygen and air mixture, cisatracurium0.03 mg/kg.

In both groups , ultrasound guided block will be performed by an experienced anesthesiologist who has no subsequent role in the study after induction of anesthesia and before starting of surgery in lateral position, sterilized and covered with sterile sheets. Aseptic precautions is taken by wearing sterile gowns and gloves A sterile preparation of the ultrasound probe is obligatory. Outcome parameters will be assessed by another anesthesiologist blinded to the groups of assignment.

Group 1: Technique of ultrasound guided Erector spine plane block:

The pa¬tient will be placed in in left lateral decubitus and the ultrasound-guided ESP block was performed at the(T12-L4) level on the left side.A 18_20 needle was inserted with the bevel in cephalo- caudal direction and 0.5 ml Kg of 0.25% Bupivacaine were injected Group 11: Technique of ultrasound guided Cauda block: With the patient in the left lateral decubitus position and the hips and knees flexed, the sacral hiatus can be identified using ultrasound First of all, the posterior superior iliac spines are palpated via anatomical landmarks, the line between both spines representing the base of an equilateral triangle the tip of which indicates the position of the sacral hiatus. The sacro coccygeal ligament can be palpated between the two sacral cornua, which is where the needle should penetrate the skin at an approximate 45 angle. Once the ligament has been passed, a flatter angle is adjusted by descending the needle before it can be advanced to the correct final position. Local anesthesia 0.5 ml Kg of 0.25% Bupivacaine were injected. Before application of local anesthetic , cautious aspiration or passive drainage is required to rule out an inadvertent intravascular or spinal needle location. Ultrasound guidance, by comparison ,offers two key advantages: it helps to identify small anatomical structures, and allows the spread of the local anesthetic to be seen by placing it longitudinally in a position slightly Para median to the lumbar spine .
