Discussion
Conclusions
Limitation in our study
-
Accessing haemodynamic stability limits the application of KMC to a higher gestational age (32 +/- 2 weeks) and weight (2080 +/- 270 gm) of studied infants. Even though there is a possibility for extended application of KMC for neonates with lower gestational age and lower birth weight.
-
The relatively small sample size.
-
There are other advanced ultrasonography that can calculate more measurements.
