DHA Registered Midwifery - Exam Topics Sample Questions

Transient hyperammonemia of the newborn (THAN) is a disorder occasionally present in preterm newborns but not always symptomatic. The most common and most effective treatment for THAN is which of the following?





Correct Answer:
hemofiltration
transient hyperammonemia of the newborn (than) is a metabolic disturbance observed primarily in premature infants, characterized by a sudden rise in serum ammonia levels during the first few days of life. this condition can lead to serious neurological damage if not treated promptly, although it usually resolves within a few days without specific treatment. however, in severe cases or when symptoms are evident, intervention is required.

the most common and effective treatment for than is continuous dialysis or hemofiltration. this approach helps to remove excess ammonia from the blood directly and rapidly, thereby preventing potential brain damage or other serious complications associated with high ammonia levels. hemofiltration is particularly effective because it can be adjusted to the specific needs of neonates, who are often more sensitive to changes in fluid and electrolyte balances compared to adults.

alongside hemofiltration, additional treatments may be employed to manage or support the infant's condition. nutritional support is crucial, as it helps ensure that the newborn receives adequate nutrients while avoiding excessive protein intake, which can exacerbate ammonia production. in some cases, healthcare providers may recommend limiting protein in the diet temporarily until ammonia levels stabilize.

sodium benzoate and arginine are also used as adjunct therapies in managing than. sodium benzoate works by helping to convert ammonia into a less toxic substance that can be more easily eliminated from the body. arginine, an amino acid, plays a role in the urea cycle, helping to process ammonia into urea, which is then excreted in the urine.

protein restriction may be recommended as a short-term therapeutic strategy. since the transamination of proteins (a process where amino groups are transferred from amino acids to form new amino acids) is a significant source of ammonia production, reducing protein intake can help decrease the ammonia load until the infant's condition improves.

in summary, while than can resolve on its own, severe cases require prompt and effective treatment to prevent long-term damage. hemofiltration remains the most effective treatment modality for rapidly reducing serum ammonia levels in affected newborns. this, combined with nutritional management and supportive therapies like sodium benzoate and arginine, forms the cornerstone of managing transient hyperammonemia in the newborn.
