Maxillary Nerve Blocks in Children - An MRI Study of the Suprazygomatic

Sponsor

Oslo University Hospital

Enrollment

20 participants

Start Date

Jun 7, 2023

Study Type

INTERVENTIONAL

Conditions

Analgesia Nerve Block Cleft Palate

Summary

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

Min Age: 10 MonthsMax Age: 24 Months

Inclusion Criteria4

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 Criteria5

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.
