Brief Summary

This study aims to evaluate the accuracy of temperature change (ΔT) measurements using infrared thermography to predict a successful erector spinae plane block in pediatric patients undergoing inguinal hernia repair under general anesthesia.

Conditions

Infrared; Thermography; Prediction; Erector Spinae Plane Block; Unilateral Inguinal Hernia Surgery; Paediatric

Outcome Measures

Primary Outcomes (1)

• Predict successful ESPB

  The ability to predict a successful erector spinae plane block by infrared thermography through the change in temperature (ΔT) (degrees Celsius) between the blocked and unblocked sides of the same dermatomal level in the mid-clavicular line throughout 20 minutes of block.

  Throughout 20 minutes of block

Secondary Outcomes (6)

• Degree of pain

  12 hours after surgery

• Heart rate

  Till discharge of the patient (Up to 12 hours)

• Systolic blood pressure

  Till discharge of the patient (Up to 12 hours)

• Mean arterial blood pressure

  Till discharge of the patient (Up to 12 hours)

• Number of doses of rescue analgesia

  12 hours after surgery

Study Arms (1)

Study group

Children undergoing elective unilateral open inguinal hernia surgery.

Device: Infrared Thermography

Interventions

Infrared Thermography DEVICE

Infrared thermography will be used to predict the success of an erector spinae block by measuring the temperature difference between the blocked and unblocked sides.
