Summary

This summary is machine-generated.

Natural drying significantly reduced umbilical cord separation time compared to 95% alcohol cleansing in neonates. This finding suggests traditional alcohol cleaning is unnecessary for routine umbilical cord care.

Area of Science:

Neonatal care
Dermatology

Background:

Umbilical cord care practices vary globally.
The efficacy of 95% alcohol cleansing versus natural drying for umbilical cord separation is debated, especially in humid climates.

Purpose of the Study:

To compare the effects of 95% alcohol cleansing and natural drying on umbilical cord separation time.
To evaluate the necessity of traditional alcohol-based cord care in subtropical regions.

Main Methods:

A randomized controlled trial involving 150 neonates.
Participants were assigned to either 95% alcohol cleansing or natural drying groups.
Data on cord separation time and complications were collected.

Main Results:

Natural drying significantly reduced umbilical cord separation time (p=0.014).
No significant difference in omphalitis or skin infection rates was observed between groups.
Caesarean delivery was associated with longer separation times (p=0.001).

Conclusions:

Routine 95% alcohol umbilical cord cleansing is not necessary and does not expedite separation.
Natural drying is an effective and potentially superior method for umbilical cord management.
These findings challenge traditional neonatal care practices in high-humidity environments.
