The following treatments are frequently indicated for infants with HIE: Babies with HIE often develop physical and intellectual disabilities and long-term health conditions. It may also be necessary to deliver via C-section before the membranes rupture, so the baby is not exposed to infection via vaginal delivery. There are often secondary effects of hypoxia on cardiac myocytes, causing reduced cardiac output and causing further secondary neurological injury. hypoxic-ischemic brain injury is diffuse brain damage due to reduced blood flow (ischemia) and/or reduced oxygen supply or utilization (hypoxia) to brain tissue; cardiac arrest is the most common cause in adults ( Pract Neurol 2011 Feb;11 (1):4) Also Called hypoxic-ischemic encephalopathy hypoxic encephalopathy globally ischemic brain Definitions Pupils are non-reactive to light.

Because the umbilical cord is the babys sole source of oxygen and nutrients, it is critical that the umbilical cord function properly. About 90 percent of the causes occur in utero, about 10 percent after birth. Encephalopathy from head injuries, toxins, cardiac arrest, or lack of oxygen to the brain causes physical damage to the brain that is usually permanent.

Diffusion-weighted MR imaging is the earliest imaging modality to become positive, usually within the first few hours after a hypoxic-ischemic event due to early cytotoxic edema. In some cases, like when a mother has an active infection during delivery, it is imperative to give antibiotics. In many cases, adequate screening and proper prophylactic treatment (preventative measures) can stop the baby from becoming infected or stop the infection before it causes brain damage.
