Necrotising Fasciitis of Neck in a 7 Day Neonate Following Insect Bite

Abstract

Necrotizing fasciitis is severe inflammation of the muscle sheath that leads to necrosis of the subcutaneous tissue and adjacent fascia. The disease entity is more commonly described in adults and the literature seems quite sparse with respect to children and even lesser in neonates. Monomicrobial infection with necrotizing fasciitis in Neck following insect bite is rare and even rarer in neonates. 07 day old neonate had history of rapid onset discoloration and swelling of the Right side of Neck following an insect bite which was followed fever and irritability and eventually black discoloration. The neonate was irritable with excessive crying, had tachycardia, tachypnea and was febrile. There was a diffuse swelling in the right side of neck with multiple patchy areas of tissue necrosis in form of blackening of the skin over the swelling Management: Necrotizing fasciitis was identified early and the neonate prepped for surgery. All the biochemical parameters were WNL. CRP was raised. Empirical treatment with Cefotaxime, Clindamycin and cloxacillin started and neonate taken for local debridement. All necrotic tissue was removed including tail of parotid. Over next 5 days serial debridement and wound wash with Hydrogen peroxidase, Betadine, saline and metronidazole was done. The edges of the wound became healthy with no new slough formation and necrotic tissue. An early diagnosis and definitive management with both surgery and antibiotics is the key to a reduce mortality in the neonates. It needs to be followed up with good local wound care.
