Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Continuous intravenous insulin infusion starting at 0.05 units/kg.hour, titrated to maintain target blood glucose levels. In the intervention group insulin will be started in hyperglycaemic babies after two concecutive blood glucose levels of > 8.5 mmol/l, 4 hours apart. The insulin will be titrated to maintain the blood glucose level from 4-6 mmol/l.
Intervention code [1] 1106 0
Treatment: Drugs
Comparator / control treatment
n the control group insulin will only be started in hyperglycaemic babies who are over 3 days old, and have persistently elevated blood gluocose levels > 10 mmol/l, and unable to tolerate 100 cal/kg.day. Once insuin is started the dose will be titrated to maintain the blood glucose level 8-10 mmol/l. The trial will continue until 36 weeks post menstrual age.
