NICU Language

With your baby being admitted to the NICU you will learn a whole new language. Use this glossary to help you understand and even speak this foreign language with as little effort as possible. Terminology and people included are according to the South African context. This page is brought to you with the courtesy of Prematurity – Adjusting your Dream.

GLOSSARY OF NICU TERMS

The people and terminology for them:

  • ICU: Intensive Care Unit
  • NICU (Neonatal Intensive Care Unit): This specialized unit is where premature babies or very sick babies are monitored and cared for. It can also be referred to as Special Care Nursery (SCN) or Intensive Care Nursery (ICN).
  • Neonate: This is how an infant is described for the first thirty days of their life.
  • Premature infants: This is a baby born before 37 weeks gestation. These babies are often referred to as 'premmies'.
Prematurity can be further defined according to the baby's birth weight:
Low birth weight baby < 2500 grams at birth
Very low birth weight baby < 1500 grams at birth
Extremely low birth weight baby < 1000 grams (micro premmie)


PEOPLE

Many professionals work together to care for premmie babies. You may meet some or all of the following:

  • Audiologist: person who specialises in hearing problems, tests for hearing loss and the treatment thereof.
  • Cardiologist: doctor who specialises in heart problems.
  • Case manager: person involved with medical aids. She will reassess your baby's medical status daily and keep the medical aid informed. She will also contact you if there are any problems from the medical aid's side. If you have queries on whether you have sufficient funds from your medical aid to cover the care of your baby while in NICU, this will be the person to speak to.
  • Endocrinologist: doctor that specialises in gland and hormonal problems.
  • Lactation consultant: health care provider who has advanced training and certification in breastfeeding management. In some NICUs the lactation consultant is available to help the nursing mother establish and maintain a breast milk supply until her baby is ready to breastfeed. The consultant then helps mothers with the actual skill of breastfeeding. If your NICU does not have a lactation consultant appointed to the unit, the neonatal nurses might help you in this regard, but you might find it useful to contact a lactation consultant once you go home and need additional support.
  • Neonatal nurse: registered nurse who is specially trained (referred to as a trained neonatal sister) or experienced (referred to as an experienced neonatal sister) to provide nursing care to high-risk, premature and ill newborns. She performs and coordinates the many tasks necessary to care of your baby. She will also look after the family and show you how to take care of your baby.
  • Neonatologist: specialised paediatrician in high-risk, premature babies. She will supervise the medical care of your baby.
  • Nephrologist: specialised doctor in kidney (urine) problems.
  • Neurologist: specialised doctor in brain and nervous system problems.
  • Occupational therapist: specially qualified person in the promotion of development and treating of developmental problems. You may encounter this person either in the NICU or in a follow-up clinic visit.
  • Opthamologist: specialised doctor who will check your baby's eyes and provide appropriate treatment.
  • Paediatrician: specialised doctor in child health care. You will probably take your baby to your own paediatrician after discharge from the NICU.
  • Pathologist: specialised doctor in blood problems. This doctor will analyse your baby's blood results and send a report with the results to the NICU.
  • Physiotherapist: specially qualified person in assessing movement and muscle problems in babies. They are sometimes also involved in the treatment of respiratory problems. You may meet one in the nursery or later in a follow-up clinic.
  • Radiographer: person who will take X-rays of your baby's lungs and abdomen. These X-rays may be repeated a few times a day when your baby is still very ill or when necessary when your baby is getting stronger.
  • Radiologist: specialised doctor who evaluates and writes a report on the X-rays.
  • Shift leader: neonatal nurse who is second in charge when the unit manager is on duty. She is responsible for the management of the NICU when the unit manager is unavailable.
  • Social worker: qualified person who can help you with non-medical issues. She can assist you by providing counselling, emotional support, information on community resources and where the need arises, financial information.
  • Speech and language specialist: qualified person trained in speech and language development and problems. If this person is also a qualified feeding therapist, she will play an important role in assisting your baby with feeding problems, such as sucking and swallowing difficulties.
  • Unit manager: neonatal nursing sister who is in charge of the NICU. She supervises all nurses and clerks in the NICU. You are welcome to contact her with any queries or problems you might experience that cannot be solved by speaking with other nursing staff.
  • Ward secretary: receptionist in the NICU. She will often be the one answering the phone in the unit and can help you with all kinds of administrative information and activities.

 

SPECIAL TESTS

  • Ultrasound: a standard test that takes an ultrasound image of any of your baby's organs by means of sound waves producing images. Ultrasound scans are simple, painless procedures and contain no radiation. Head sonar scans can be used to check for areas of bleeding from weakened or broken blood vessels in the brain. An ultrasound of the heart can be used to examine the heart to detect any abnormalities or expected conditions for premature babies, such as a patent ductus arteriosus (PDA), which is a little hole in the heart that did not close soon enough after birth. Ultrasounds can also be performed on your baby's kidneys and stomach.
  • X-ray: the most common type of imaging scan. It can show the condition of the lungs and other organs and check the position of any tubes or catheters inserted in your baby's body. For some conditions, your baby may have several X-rays a day. This may be worrying, but there is no need to be concerned, since an X-ray is a painless procedure and experts agree that the amount of radiation used is too low to cause harm to your baby, now or in the future.
  • Echocardiogram: an ultrasound of the heart that shows the blood flow and heart chambers and vessels to determine any heart problems.

 

LABORATORY TESTS

  • Blood gases: to check levels of oxygen, carbon dioxide, and acids in the blood.
  • Blood cultures: to tell if your baby has an infection.
  • Chemical (electrolyte) balance: to determine levels such as salt and bicarbonates.
  • Blood glucose levels: to determine blood sugar levels.
  • Bilirubin level: to check for jaundice.

  • Hematocrit: to check for anaemia, which is an abnormal low number of oxygen-carrying red blood cells in the blood.

 

MEDICAL TERMS

  • Alveoli: These are tiny sacs in the lungs that exchange oxygen and carbon dioxide with the bloodstream.
  • Antibodies: These are proteins that help to fight harmful viruses or bacteria.
  • Aorta: This is the main artery leading from the heart. Oxygen-rich blood is supplied to the rest of the body this way.
  • B.I.D.: An abbreviation derived from a Latin term, meaning twice daily.
  • Bilirubin (Bili): This yellow substance occurs when red blood cells break down. Your baby's skin may take on a yellowish tint because of excess bilirubin. In large quantities, bilirubin may cause a certain form of brain damage.
  • Blood pressure (BP): The top number of your baby's blood pressure is called the systolic pressure. This indicates the pressure that is exerted when your baby's heart contracts and sends blood to your baby's body. The lower number, the diastolic pressure indicates the pressure that is exerted between heartbeats. see Low Blood Pressure
  • Breast Milk (B/M): Self Explanatory
  • Breastfed or Breastfeeding (BF): Self Explanatory
  • Bronchial tubes: These are the larger tubes that go from your baby's trachea to their lungs.
