Neonatal jaundice can be defined as a relatively common condition in which there is a yellow discolouration of the skin and eyes of a newborn. The condition occurs due to relatively high blood levels of bilirubin- the yellow pigment formed during degeneration of the red blood cells in the body. It usually is a harmless condition although some present the need for attention from the medics. It is in knowing, from its rationale to the treatment options, what causes it, its signs, and its causative treatment options, to the extent of knowing whether a neonate who had acquired it would still be able to stay healthy thereafter.
Neonatal jaundice or neonatal icterus is the yellowish discolouration of the skin and mucous membrane within the initial postnatal week due to the excessive bilirubin of the circulating blood. Usually, bilirubin represents the breakdown product of the heme part of haemoglobin and is metabolized in the liver and excreted into urine and stool. However, the neonatal stage is not an uncommon phase in which the liver is immature enough to handle the workload of bilirubin gathering in the self and hence present oneself with jaundice.
Neonatal diagnosis of jaundice is indeed very important on the part of health practitioners and the parent. Early diagnosis and treatment will enable the child to evade its associated complications such as kernicterus - a complication very rare resulting from the extremely high levels of bilirubin that causes brain damage. The cause, signs, and modes of treatment will be informative to parents in enabling them to take necessary precautions concerning their newborns' health.
It is, therefore, classified as physiological jaundice-the most common form of neonatal jaundice-and it affects about 60% of full-term newborns and 80% of preterm infants. It tends to appear from days two to four of life and disappears by two weeks of life. It is thus called normal physiological neonatal jaundice since it occurs because of an inability of the immature liver to process the bilirubin fast enough. Pathological Jaundice
However, pathological jaundice is comparatively serious and may even develop in some babies within 24 hrs of being born. It can thus be associated with some underlying abnormality, generally because of excessive hemolysis or inefficient handling of bilirubin. Unlike physiological jaundice, pathological jaundice invariably demands attention from the medical fraternity.
Blood group incompatibility jaundice: The blood group incompatibility between mother and child usually destroys the newborn RBC; hence, it affects the occurrence of blood group incompatibility jaundice. Preterm birth: in the case of a preterm infant, the liver is immature and hence highly vulnerable to failure in processing bilirubin out of the body. Poor feeding problems: poor lactation may result in dehydration; and less bilirubin being excreted because of less frequency passing urine and stool.
Infections Infection, through sepsis, can cause liver failure to process bilirubin Clinical Manifestations of Neonatal Jaundice Identifying the Signs and Symptoms of Jaundice The most obvious manifestation of neonatal jaundice is when the skin and also the whites of the eyes become yellow. The yellow discolouration starts from the face down to the chest, abdomen and lower extremities, depending on the severity of bilirubin. Characteristics of more serious conditions that exhibit jaundice include the following:
Poor feeding Lethargy High-pitched crying Dark-coloured urine Pale-coloured stool How Jaundice Presents in Newborns The presentation of jaundice may vary in the newborn depending on the cause and degree of rise. It may be mild where yellow discoloration of mucous membranes appears only on the face and the upper part of the body or it may be so high that the whole body may assume yellow colouration. Back bending of the body, and seizure in newborns with very high levels of bilirubin amongst other neurological manifestations may be present. It can be regarded as a neurological emergency.
Diagnosis of neonatal jaundice mainly includes physical examination and a set of tests that determine the level of bilirubin. This includes but is not limited to the following.
Transcutaneous Bilirubinometry: A non-invasive device employed in measuring the bilirubin levels through the skin.
Serum Bilirubin Test: A blood test that is utilised in exacting bilirubin levels in the bloodstream.
It is measured in milligrams per deciliter of blood. The level that is considered normal for all newborns, whatever the age or gestational age is usually less than 1 to 12 mg/dL. Those whose levels exceed this may be considered for treatment. A decision to treat is based on the infant's age, bilirubin level and risk factors.
It should be labelled whether physiological or pathological as such information would provide appropriate management. Physiologic jaundice tends to present later and is self-limiting whereas pathologic jaundice tends to present early and is part of other symptomatology and conditions that have to be treated.
Watch for the following signs and symptoms in your newborn and call their doctor if you suspect jaundice: Yellow appearance of the skin and sclera Poor feeding or unable to feed Unusual sleepiness, lethargy Dark Coloured urine Pale or clay-coloured stools.
Jaundice that begins within the first 24 hours of life, its early progression or severe manifestations in the form of excessive lethargy, high-pitched cry, or seizure demand immediate consultation with the physician.
Management Interventions for Neonatal Jaundice
One of the most general methods of treatment relating to neonatal jaundice is phototherapy. A baby will be kept under a special kind of light that helps in breaking bilirubin into an easily excreting form. Phototherapy often becomes necessary for babies with moderately high levels of bilirubin and is continued until levels go down to a safer range.
The indication for replacement transfusion is severe hyperbilirubinemia which, despite adequate phototherapy, remains jaundiced. It is a procedure of removal of the baby's blood in small amounts and its immediate replacement with donor blood, thus reducing the bilirubin concentration. However, replacement transfusion can be done only in infants with a particularly high chance of developing kernicterus or other devastating complications.
Available Interventions apart from the Above Discussed Phototherapy and Exchange Transfusion;
Intravenous immunoglobulin: this is used in case of blood group incompatibility to avoid exchange transfusion
Hydration and feeding supportive care: good hydration and nutrition would help to reduce the bilirubin levels through frequent bowel movements and excretion.
It is a rare form of jaundice associated with the feeding through breast milk. This probably occurs in the second week or late during the first week of life. The actual cause is thought to be because of some substances' action in the milk of the breast which breaks down the breakdown pathway of bilirubin. Unlike other types of neonatal jaundice, no particularly onerous noxious effects afflict the infant. Thus, if one reads between the lines of scientific literature then one may find that it subsidises the passage of time as part of its natural course and sans any need for treatment.
It is also said to differ in time and etiology from all the rest in that it usually presents much later. However, no underlying medical condition has ever been identified that presents this form of neonatal jaundice. Otherwise, infants with breast milk jaundice are healthy showing normal weight gains.
Most breast milk jaundice is benign and does not require intervention. It has always been advised that breastfeeding must be continued. It is only if the bilirubin does rise to an unusually high level of serious concern that intervention may be required in such instances. This is very seldom encountered and whenever this is necessary, it can be carried out with the aid of using phototherapy.
Treatments of neonatal jaundice are focused on the reduction of bilirubin to avoid the complication. Their modes of treatment vary in their degree of severity and include:
Phototherapy: Under bright light
Exchange transfusion: Very severe cases where the problem isn't affected by the treatment of phototherapy
Intravenous immunoglobulin: In case of blood type incompatibility.
Efficacy and Risks of Various Treatments
Each of these has certain advantages and disadvantages. Among all the above three therapies, phototherapy is the safest and most effective as the fewest numbers of its side effects are recorded. Much effective treatment through exchange transfusion may provide a passage of infection and blood clots. The IVIg is thought to be quite safe though in some infants it was found that allergy due to this type of treatment has taken place.
Each Newborn would fit into one of the management categories depending on the condition as well as the associated risk, which could result in a complication.
Fortunately, most neonatal jaundice resolves without harm. Significantly jaundiced neonates and those on treatment do require close follow-up at the time of discharge to ensure bilirubin levels remain safe. This may often be accomplished in the context of routine well-baby office
visits but sometimes require further testing.
Untreated severe jaundice results in the state of a damaged brain medically termed kernicterus manifested leading to permanent disablement. Other sequelae of untreated severe jaundice are impairment of hearing and problems in vision.
All these sequels are avoided because of one thing; early detection and management.
Although neonatal jaundice per se cannot be completely prevented, some measures can be taken to prevent the risk for neonatal jaundice as follows:
Antenatal care: Routine antenatal visits will help the doctors identify most of the risk factors well in advance that may be the cause of jaundice in a newborn.
Good attachment and frequent feeding are required or else the baby will poorly suck and get dehydrated and jaundiced.
Monitoring of high-risk infants: Because of so many risk factors, either because the baby was premature or due to blood group incompatibility, the baby has to be keenly monitored after birth.
Counselling on prenatal and postnatal care
In other words, good prenatal and postnatal care offers the requisite opportunity for prevention and control of neonatal jaundice: antenatal care, good nutrition, proper feeding, and hydrating of the infant.
Neonatal jaundice is one of the most frequent problems a newborn baby has to put up with. It usually happens some days after birth and, in most cases, manages to cure itself. Sometimes it may require some medical interference, though. Good knowledge of its causes and symptoms bodes comfort on the part of the parents or guardians; hence, having such a baby go through and grow healthy is easy.
They must be aware of the signs, diagnose whether jaundice has kidnapped their baby, and refer to an infant doctor if they are the least worried by symptoms and signs. Fortunately, for most babies who experience neonatal jaundice, proper care, and treatment lead a full and healthy life.
Yes, if there is no proper diagnosis and treatment followed by such a diagnosis, then it could be complicated.
If there is any plausible occurrence of complicacies, where the life of the neonatal is under question, at that time counselling matters.
Phototherapy: Under bright light; Exchange transfusion: Very severe cases where the problem isn't affected by the treatment of phototherapy; Intravenous immunoglobulin: In case of blood type incompatibility.
