Case series: Use of Glyceryl Trinitrate patches to improve peripheral circulation in children with severe neurodisability.

ABSTRACT

AIM: Evaluation of topical Glyceryl trinitrate as a therapeutic option to improve peripheral circulation in 16 children with severe complex neurodisability, poor capillary return and signs of vascular insufficiency, including discomfort. METHODS: If insufficient improvement in capillary return was obtained using conservative measures, a 5 mg GTN patch was placed each day on the front of the tibia of each leg. Children were reviewed clinically for up to 12 months of treatment. Distal limb comfort was measured using a Likert scale, either patient or carer reported. Standardised capillary refill time was assessed at each clinical review. RESULTS: Use of the patches led to improved capillary refill time and parent/patient reported comfort in all children. Healing of skin ulcers in lower limbs after application of the patch was also noted. There was universal parent/patient satisfaction with use of the patch. One child with Aicardi Goutieres syndrome had a skin reaction with prolonged use and minor adverse effects were reported in 4 others but this did not result in discontinuation of treatment. SUMMARY: GTN patches were relatively well tolerated in this group of children. We suggest that use of GTN patches be considered for children with severe neurodisability and poor peripheral circulation causing discomfort. GTN patches may also have a role in healing of persistent skin ulcers for these children.
