Ultrasound-Guided Transversalis Fascia Plane Block Versus Caudal Block for Postoperative Analgesia in Children Undergoing Inguinal Herniorrhaphy: A Randomized Controlled Non-Inferiority Trial

The aim of this study is to compare ultrasound-guided transversalis fascia plane block and caudal block for postoperative analgesia in children undergoing inguinal herniorrhaphy.

Study Overview

Detailed Description

Surgical repair of inguinal hernia is one of the most common day-case surgeries in the pediatric population. It is associated with significant postoperative pain and discomfort.

Caudal block analgesia is a popular and reliable technique for lower abdominal surgeries and found to be safe and effective for providing intra and postoperative analgesia in pediatric patients.

transversal fascia plane block (TFPB) aims to provide analgesia for invasive procedures of the inguinal and sublingual areas by blocking the subcostal (T12), ilioinguinal (L1) and iliohypogastric (T12-L1) nerves. Several studies have reported TFPB as the analgesic method of choice for procedures involving the T12-L1 dermatome region, including iliac bone graft harvesting, cesarean section, and inguinal hernia repair

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time to the 1st rescue analgesia
Time Frame: 24 hours postoperatively
Time to the first request for the rescue analgesia (time from the end of surgery to first dose of paracetamol administrated).
24 hours postoperatively

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Intraoperative fentanyl consumption
Time Frame: Intraoperatively
Additional fentanyl bolus dosages of 1 µg/kg IV will be administered if heart rate or mean arterial blood pressure elevated more than 20% of the baseline (after exclusion of other causes than pain).
Intraoperatively
Total paracetamol consumption
Time Frame: 24 hours postoperatively
Each of the five items of the Face, legs, activity, cry, and consolability (FLACC) scale will be scared, ranging from 0 to 2, which will be then aggregated to obtain a total score ranging from 0 to 10. Higher scores on the scale indicated a higher level of pain intensity. If the FLACC scale exceeds three, IV paracetamol (15 mg/kg) will be given.
24 hours postoperatively
Degree of pain
Time Frame: 24 hours postoperatively
Degree of pain will be assessed using the Face, legs, activity, cry, and consolability (FLACC) scale. Each of the five items of the FLACC scale will be scared, ranging from 0 to 2, which will be then aggregated to obtain a total score ranging from 0 to 10. Higher scores on the scale indicated a higher level of pain intensity.
24 hours postoperatively
Hear rate
Time Frame: Every 15 min till the end of surgery (Up to 2 hours)
Hear rate will be recorded preoperatively, before performing of block, and every 15 min till the end of surgery.
Every 15 min till the end of surgery (Up to 2 hours)
Mean arterial pressure
Time Frame: Every 15 min till the end of surgery (Up to 2 hours)
Mean arterial pressure will be recorded preoperatively, before performing of block, and every 15 min till the end of surgery.
Every 15 min till the end of surgery (Up to 2 hours)
Degree of patient's parents satisfaction
Time Frame: 24 hours postoperatively
Degree of patient's parents satisfaction will be assessed on a 5-point Likert scale patient satisfaction (1, extremely dissatisfied; 2, unsatisfied; 3, neutral; 4, satisfied; 5, extremely satisfied)
24 hours postoperatively
Incidence of adverse events
Time Frame: 24 hours postoperatively
Incidence of adverse events such as bradycardia, hypotension, nausea, vomiting, respiratory depression, or any other complication related to block such as hematoma, neurological injury, deep visceral injury, or local anesthetic toxicity will be recorded.
24 hours postoperatively
