Prevention

Because the causes of CP are varied, a broad range of preventive interventions have been investigated.

Electronic fetal monitoring has not helped to prevent CP, and in 2014 the American College of Obstetricians and Gynecologists, the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, and the Society of Obstetricians and Gynaecologists of Canada have acknowledged that there are no long-term benefits of electronic fetal monitoring. Before this, electronic fetal monitoring was widely used to prop up obstetric litigation.

In those at risk of an early delivery, magnesium sulphate appears to decrease the risk of cerebral palsy. It is unclear if it helps those who are born at term. In those at high risk of preterm labor a review found that moderate to severe CP was reduced by the administration of magnesium sulphate, and that adverse effects on the babies from the magnesium sulphate were not significant. Mothers who received magnesium sulphate could experience side effects such as respiratory depression and nausea. However, guidelines for the use of magnesium sulfate in mothers at risk of preterm labour are not strongly adhered to; in 2017 only 2 in 3 eligible women in the UK received the medication despite it being recommended by NICE guidelines. An NHS quality improvement programme increased its usage in England from 71% in 2018 to 83% in 2020.

Caffeine is used to treat apnea of prematurity and reduces the risk of cerebral palsy in premature babies, but there are also concerns of long term negative effects. A moderate quality level of evidence indicates that giving women antibiotics during preterm labor before her membranes have ruptured (water is not yet not broken) may increase the risk of cerebral palsy for the child. Additionally, for preterm babies for whom there is a chance of fetal compromise, allowing the birth to proceed rather than trying to delay the birth may lead to an increased risk of cerebral palsy in the child. Corticosteroids are sometimes taken by pregnant women expecting a preterm birth to provide neuroprotection to their baby. Taking corticosteroids during pregnancy is shown to have no significant correlation with developing cerebral palsy in preterm births.

Cooling high-risk full-term babies shortly after birth may reduce disability, but this may only be useful for some forms of the brain damage that causes CP.
