What Causes Jaundice In Newborns - Causes | Symptoms | Treatments - Wit Biology

                                        INFANT JAUNDICE 


     Neonatal jaundice (Infant Jaundice)... So just to run through what we're discuss undergo Definitions, the causes of neonatal jaundice, clinical features, investigations and management.

    So why can we got to study neonatal jaundice overflow 60% of newborns become Dauntless this might be physiological or it's going to flow from to underlying disease and this might have serious consequences as high unconjugated serum bilirubin is neurotoxic and may cause deafness connectors and athetoid spastic paralysis . Just to run through some definitions a neonate is defined as between birth and until 28 days postnatally and jaundice is when the serum bilirubin is over 30 millimoles per liter.


       So what are the causes of neonatal jaundice well it's best to divide these into causes according to the age of onset of jaundice as this is a useful guide to the likely cause. So if the baby develops darkness within 24 hours it's always a hematological condition like recess hemolytic disease ABO incompatibility g6pd deficiency or maybe it might be a congenital infection between 24 hours and a couple of weeks might be physiological jaundice which we'll discuss in additional detail later or breast milk.

    Jundice also are infection again hemolytic disorders or breathing if the baby develops jaundice when they're over fortnight old it is vital to divide these inter unconjugated bilirubin and conjugated bilirubin. The unconjugated causes are again physiological and breast milk jaundice again infection. But also hypothyroidism and the hemolytic disorders. If the bilirubin is conjugated then the causes might be sepsis, TPN, Neonatal hepatitis, CF or common bile duct obstruction. So just to debate during a bit more detail physiological jaundice is extremely common so often starts when the baby is 24 hours old it peaks at a couple of days but always resolves by day 14 the mechanism is thanks to the immaturity of hepatic bilirubin conjugation an action is required.

    If the serum bilirubin is over 260 millimoles per liter breast milk .Jaundice is when jaundice is exacerbated just thanks to the contents of what is within the breast milk the cause for this is often often unknown infection is additionally a crucial explanation for jaundice and this is thanks to variety of mechanisms. Firstly poor fluid intake by the infant hemolysis reduced hepatic function or a rise in entero hepatic circulation conjugated jaundice is usually recommended by dark urine and pale stools. Billary atresia is a crucial cause to recollect therefore the clinical features of neonatal jaundice are firstly that the jaundice progresses during a cough alack caudal direction. It's observed most easily by directly blanching the skin and in direct sunlight the manifestations of connectors are lethargy poor feeding irritability and increased tone.

    So to run through the investigations that you simply do for a neonate that was doing this firstly you'll just do a urine dip to rule out a urinary tract infection and send this off the culture if necessary the investigations done within the Bloods would be that you simply had checked the extent of the serum bilirubin. There are now tons of transcutaneous bilirubin meters in hospitals. But these are often inaccurate so best to require a venous sample you'll check the hemolytic disorders by doing an FBC in film checking the blood type and doing an immediate Coombs test to see for infection a capillary blood gas is usually useful and you'll consider a septic screen. Such as lfts a tort screen TFT may be a beaker to rule out hypothyroidism.

    You can also do hepatitis serology our red blood corpuscle deflects and tests for CF imaging is required to rule out biliary atresia this might be a liver ultrasound scan or a liver biopsy or maybe medicine liver scans.

So now to debate the management of neonatal jaundice.

    The management of neonatal jaundice depends totally on the extent of the serum bilirubin and therefore the age in days of the baby. This is an example of the rules from Norway but every hospital has their own guidelines and that they all looked fairly almost like this in essence.

    The basic management is to encourage regular feeding as dehydration exacerbates jaundice and phototherapy.

    If consistent with the rules it's required this is often commonly used and lightweight waves convert the unconjugated bilirubin into harmless water soluble pigment very rarely an transfusion is required when the serum bilirubin is extremely high the prognosis for neonatal jaundice is usually good and fortunately connector assess a rare complication nowadays. But it's serious and wishes to be remembered.

    So in summary we've gone through the basic definitions of jaundice, the common causes, how to investigate it and the principles of management thanks for Reading ❤️✌️...
