So you were wrong when you initially stated that you pursue the same standard diagnostics as the rest of the world? Because what you're saying now is radically different than what you said earlier in this post. Hey, if you've got no resources to work with, then you do what you can. I don't begrudge that. But if you're going to compare your methods to that of industrialized nations, you are bound to get questions about why you didn't pursue a basic laboratory workup in a neonate. Why does that suprise you?
This is our management guidelines for all cases of neonatal jaundice
the probable causes as in any part of the world
- hemolytic dx...Rh and ABO incompatility
- G6PD Deficiency - a very common cause here, since mothers usually store babies clothing in naphthalene balls. And of course naphthalene causes hemolysis in G6PD full defect.
- Sepsis - the TORCHES or any of the common virulent flora in the birth canal
- physiologic ( which is a diagnosis of exclusion)
- enclosed bleeds or bruising
- less common causes here are hypothyroidism, galactosemia and obstructive jaundice
The initial labs would be based on the initial clinical suspicion. we don't routinely perform a battery of investigations. We try to be as specific as possible. There is a bit of disadvantage in that, because patients might present with other comobidities. A ct scan as outlined in the initial post is not done here routinely as an initial workup
These investigations form the initial work up
- Full blood count well CBC under your setting with film comment
- malaria though a common cause of Intravascular hemolysis in our environment, is not screened for in the newborn period routinely, since there is an acquisition of maternal antibodies. we live in a hyperendemic area.
- Serum Bil estimation
- Blood group of both the mother and baby
- direct coombs test on the baby's blood
- indirect coombs test on the mothers blood
- G6PD - is routinely done here, since its quite common
- Blood culture, urine and CSF cultures
- we do a full septic screen.
The prevention of kernicterus is a major aim in the managment of unconjugated hyperbilirubinaemia. our levels for starting phototherapy in a baby > 2Kg is 240 micromols per litre.
we increase fulid requirements to about 20 percent, and take the necessary precautions in phototherapy.
Exchange transfusion is usually started if the serum bil level is about 340 micmols per lit.
though it can be started at much lower levels if the rate of rise of serum bilirubin is rapid. It is also done if the cord Hb is less than 12g per dl.
However the threshold for the intervention by phototherapy or exchange transfusion is started at much lower bilirubin levels if the child is very sick, LBW, aspyxiated, prolonged hypoxaemia, acidosis or sepsis.
We perform a double volume exchange transfusion...we routinely use the veno venous technique with a three way stop cock.
For this particular case the problem was to do with fact that it was a late presentation. The serum levels of bilirubin were excessively high. And with our experience in our unit..a great portion of the babies died when they presented that late. The patient could not afford the tests. i therefore paid for the initial estimation of the levels of bilirubin, i also paid for the the initial blood culture. We started empirical antibiotic therapy since in our experience a good number of causes are due to sepsis. The history and examination was also suggestive of a possible sepsis.
We laid down the facts to the parents. The fact that the chances of survival for their baby wasn't too good. Doctors are respected here as much as they are in your country. Patients are more likely to accept the opinion of a doctor where i come from. We made it clear to them that the chances of survival of their child was still low, form our experience. They couldn't afford the exchange transfusion. I could have paid for that too, but i decided otherwise. We are not playing God, but if you see cases like the one i have described coming back to haunt you as a clinician then it becomes difficult. People see disability as a curse. Parents do not follow up at neurodevelopmental clinics. They give up on their disabled children because they don't see any hope for them. They are too poor to afford medications prescribed for them at neuro follow ups. There have been instances of patients abandoning their children. And indeed there is little hope for them when they are abandoned.
These pictures come back to haunt you as a clinician. We follow a management protocol. And in exceptional cases like this we do what we feel will be right for the parents and our poor society as a whole.
