Neonatology is the study and care of neonates. A neonatologist is a paediatrician specially trained in the care of neonates. A neonate is another word for a newborn baby and babies are considered newborn or neonates until they are one month old. Why? Because most babies die in the first month of life. So special attention has to be given to them and specially trained doctors and nurses care for them.
Unfortunately, specially trained neonatal hospital administrators do not exist in developing countries. Our administrators have difficulty understanding the need for adequate nurse:patient ratios in a NICU (1:1) or dedicated medical personnel or proper physical surroundings.
Half of all babies who die before they are one year old, die in the first month of their life. And half of those deaths occur in low birth weight (LBW) babies, ie babies who weigh under 2.5 kilos or five pounds eight ounces. The lighter the baby the higher the mortality. Worldwide, it is estimated that more than 1.4 million neonatal deaths annually are the consequence of infections with deaths occurring more commonly in LBW newborns.
Outbreaks of infection are devastating in neonatal intensive care units (NICUs). Neonates are especially susceptible because they have almost no defences against infection, have a deficient immune system which does not respond appropriately to invasion by bacteria etc, their organs are premature and do not function well, and the use of invasive devices, feeding tubes, urinary tract catheters, endotracheal tubes attached to ventilators that breathe for tiny babies who should be in their mother’s wombs and intravenous needles for administration of fluids and medications and blood and sometimes food, is necessary. All of these are abnormal and potential entry sites for germs, so infections are common and about one in every ten newborns admitted to NICUs develop infections.
Surveys conducted in NICUs in the United States in 1999 and in Europe in 2011 have shown that 11.2 per cent and 10.7 per cent of neonates were affected by infections, respectively.
In 2021, the German Neonatal Network reported on data collected between 2009 and 2017 on 14,926 infants with a birthweight below 1,500 gms (just over three pounds). Almost 12 per cent, of them developed severe infection.
This is a fact of life. Despite the impressive advances made in the care of neonates, even in the best of hands deaths from infection occur.
Managing such infants is complex and requires multidisciplinary care approach (clinicians, nurses, pharmacists, lactation consultants, social workers, biomedical engineers, attendants etc) supported by medical decisions made during family-based care rounds.
In 1977 when I returned home, we had “Premature” Units at the major hospitals. We did not have NICUs.
In those days, half of all the babies admitted to the Premature Unit died and nobody cared. The three general paediatricians, who all returned within three months of each other at that time, walked around in a state of shock for months. Fifty per cent mortality, about thirty each month. That went on for about ten years until two Trinidadian neonatologists returned home and the mortality fell accordingly. Despite major problems in the neonatal units, it’s fascinating how far we have come.
One of the major problems, if not the major, is that we do not have a proper, purpose-built NICU in the country. We have converted “Prem Units” that are overcrowded and understaffed. We have known this since 2003, when Jamaican Dr Barbara Johnson, PAHO temporary Adviser on Paediatrics and Trinidadian Yvette Holder, Consultant Biostatistician and Epidemiologist, presented a PAHO-sponsored review of the four neonatal units at POSGH, SFGH, Mt Hope Women’s Hospital and the Sangre Grande County Hospital, titled, “Analysis of perinatal and neonatal mortality.”
Their major finding was the “Unsatisfactory Design of the Neonatal Units at PoSGH and SFGH, with chronic overcrowding at Port-of-Spain, San Fernando and Mt Hope.” Recommendations were made to “Expedite plans to extend and modify the nursery at SFGH; extend the PoSGH nursery into unused area and erect the new nursery at PoSGH as proposed.” That was 22 years ago.
They also found that there were “Regular outbreaks of infections at the three larger institutions due to a shortage of trained ICU nursing staff with unsatisfactory nurse-patient ratios and an absence of trained ICU dedicated medical staff” and recommended among other things that “Infection Control Units be strengthened”.
That some of this has taken place is undoubtedly true but the babies are still taken care of in the old-time “Prem Unit” areas.
Despite optimal treatment, neonatal sepsis continues to have high mortality rates and poor outcomes. While the mortality rates have declined substantially, further progress is difficult unless the recommendations of the 2003 PAHO team are followed. But that depends on politicians and administrators and it ain’t going to happen soon.
