A new approach to skin extravasation injury management during the neonatal period

Abstract

Abstract Background To identify a standard protocol for managing extravasation injuries in neonates. Methods We recruited all the neonates with extravasation wounds from the neonatal intensive care unit of Shariati hospital, Tehran, Iran, between October 2018 and October 2020. Sixteen patients with grade 3–4 extravasation were evaluated in this retrospective study. All grade 3 and 4 extravasation wounds were injected with hyaluronidase at 5 points of the wound circle; the procedure was repeated every 5 min at different points in a smaller circle to the core. The wound was then covered with a warm compress for 24 h. Twenty-four hours after injection, the cover was changed twice a day with normal saline irrigation. Fibrinolysin ointment was applied on top of the wound. The ulcer was then dressed with phenytoin ointment until healing. Results Out of 16 neonates who were followed up, 10 of them were male, with the average birth weight being 1.37 (range 1.05–3.75) kg. The mean (± SD) wound healing duration was 13.12 (± 6) (range: 7–29) days. Factors including the cannulation duration before the appearance of the lesion (R:0.2, P = 0.2), birth weight (R = -.37, P = 015), and extravasated substances (p = 0.2) were not associated with the duration of hospital stay. The only exception to this trend is the wound size factor of 7.31(± 7.45) (R = .83, P < 0.001). Continuous and categorical variables were summarized as mean (SD) and proportions, respectively, and the Kruskal–Wallis test and Spearman correlation coefficients were used. Conclusions Limited evidence exists on the effects of different protocols on extravasation management in neonates in the NICU. We recommend our method as a standard protocol in NICU for high-stage extravasated lesions because of the shorter duration of healing, non-invasive nature of this procedure, and lack of side effects or surgical involvement.
