Continuous feeding may have little to no effect on length of body growth or head circumference and the effects of continuous feeding on the risk of developing necrotising enterocolitis is not clear.Since preterm infants with gastro-oesophageal reflux disease do not have a fully developed antireflux mechanism, deciding on the most effective approach for nutrition is important. It is not clear if continuous bolus intragastric tube feeding is more effective compared to intermittent bolus intragastric tube feeding for feeding preterm infants with gastro-oesophageal reflux disease.For infants who would benefit from intermittent bolus feeding, some infants may be fed using the "push feed" method using a syringe to gently push the milk or formula into the stomach of the infant. Others may be fed using a gravity feeding system where the syringe is attached directly to a tube and the milk or formula drips into the infants stomach. It is not clear from medical studies which approach to intermittent bolus feeding is more effective or reduces adverse effects such as apnoea, bradycardia, or oxygen desaturation episodes. High volume feeds
High-volume (more than 180 mL per kilogram per day) enteral feeds of fortified or non-fortified human breast milk or formula may improve weight gain while the pre-term infant is hospitalized, however, there is insufficient evidence to determine if this approach improves growth of the neonate and other clinical outcomes including length of hospital stay.
The chances of survival without any long-term difficulties are lower. Signs and symptoms
Signs and symptoms of preterm labor include four or more uterine contractions in one hour. In contrast to false labour, true labor is accompanied by cervical dilatation and effacement. Also, vaginal bleeding in the third trimester, heavy pressure in the pelvis, or abdominal or back pain could be indicators that a preterm birth is about to occur. A watery discharge from the vagina may indicate premature rupture of the membranes that surround the baby. While the rupture of the membranes may not be followed by labor, usually delivery is indicated as infection (chorioamnionitis) is a serious threat to both fetus and mother. In some cases, the cervix dilates prematurely without pain or perceived contractions, so that the mother may not have warning signs until very late in the birthing process. Causes
The main categories of causes of preterm birth are preterm labor induction and spontaneous preterm labor. Risk factors
The exact cause of spontaneous preterm birth is difficult to determine and it may be caused by many different factors at the same time as labor is a complex process.
