The fluid inside the blister is clear, yellowish and shows negative results on bacterial cultures.
[12] A newborn who was born to a 26-year-old Caucasian women at the 41st week of gestation was seen with 2 round erosions on the left wrist in the postpartum examination.
[5] Another newborn who was born to 34-year-old woman via untraumatic natural delivery at her 39th week of gestation was seen with an erosion on her left forearm via examination happening just after birth.
There was no relevant history regarding the mother's or neonate's health condition during gestation to explain the cause of this lesion.
During examination, the newborn did show sucking of the affected area which helped to ease their parents that the blister happened in the womb.
This was to prevent the baby to suck on their own hand, and allow the wound to stay clean and dry for proper healing.
[14] A newborn, who was born at the 38th week of gestation, was seen with blisters on both lips during a physical examination happening right after birth.
[2] Demographic data There was a prospective cohort descriptive study conducted on one thousand newborns born from September 2015 to 2016 in Northeast Thailand to try and identify any types of skin conditions during their first five days post-birth.
To check for infection, the process includes examining the neonate's body for signs of inflammation, purulent discharge, or lesions.
If there is no presence of those features and the neonate seems generally healthy, it is safe to suggest it is a sucking blister, and not an infection.
[18] Due to this skin condition being so rare, this makes it difficult on clinicians to diagnose, especially those who are unfamiliar with sucking blisters specifically.
[20] If the child doesn't appear to have any infectious or other skin conditions, the diagnosis of sucking blister is made.
[13] A 1963 review estimated that every 1 in 250 children born had sucking blisters, but recent experts in the field think this number is even lower.
[21] The ones that aid successfully feeding an infant by bottle or on the breast later are rooting and sucking reflex.
[23] Frequency of sucking activity will increase toward the end of the pregnancy due to the impact of completed development of taste buds.
This vernix caseosa is important for newborns as they provide multiple functions such as prevention of water loss, skin hydration, temperature regulation, and assistance with innate immunity.
[13] Fluid initially collects between the epidermis and dermis in order to protect the deeper tissues and promote healing.
If not properly treated or left untreated, they can potentially cause major harm to the baby or even death.
For the management of closed blisters, moisturizer can be applied after the skin is cleaned with gentle cleanser and warm water.
