Overview

Ultrasound-guided suprazygomatic maxillary nerve block (SMNB) will be performed in paediatric patients with or without the aid of ultrasound guidance. Magnetic resonance imaging (MRI) is used to visualize the spread of the local anaesthetic (LA) spread after suprazygomatic injection and to verify LA contact with the maxillary nerve in the pterygopalatine fossa (PPF).

Eligibility

Inclusion Criteria:

  • Paediatric patients scheduled for cleft palate (CP) surgery with SMNB as part of their perioperative pain treatment
  • American Society of Anesthesiologists physical status 1 - 2
  • Age 10 to 24 months
  • Given informed written consent by legal guardian

Exclusion Criteria:

  • American Society of Anesthesiologists physical status > 2
  • Patients with cranial deformation
  • Patients with concomitant medical treatments or medical conditions interfering with peripheral nerve block treatment
  • Patients with concomitant medical treatments or medical conditions interfering with MRI
  • Patients that are allergic to bupivacaine or other local anaesthetic agents.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
