A micro preemie is a baby who is built-in weighing less than 750 grams, or before 26 weeks gestation. Since micro preemies are born months earlier their due dates, they face long stays in the neonatal intensive care unit (NICU). Although many extremely premature babies grow upward with no long-term effects of premature birth, some face severe health problems throughout life.

Premature Baby vs. Micro Preemie

Any babe who is born earlier 37 weeks gestation is considered to be premature (too known as preterm). The World Health Organization (WHO) defines prematurity based on when a baby is built-in. Babies built-in earlier 28 weeks are considered "extremely preterm." Those built-in betwixt 28 and 32 weeks are considered "very preterm." Babies are considered "moderate" to "late preterm" if they are born between 32 and 37 weeks.

Micro preemies are the nearly premature babies of all, born on or before 26 weeks. Many people are surprised by how small micro preemies are. Their skin is thin, with visible veins, and information technology may wait viscous or gelatinous. If you are visiting a micro preemie in the NICU, you lot can expect to encounter the following:

Respiratory back up: Micro preemies usually have endotracheal tubes (ET tubes) coming from their mouths. The tube is attached to a ventilator that helps the babe breathe. Some micro preemies tin can breathe on their own and will be on continuous positive airway force per unit area (CPAP) instead. These babies will have CPAP masks strapped over their noses.
Intravenous lines (IVs): If a micro preemie's digestive arrangement is too immature to absorb nutrition, they will be fed intravenously. Most volition have lines in their umbilical cord stumps (called umbilical lines) for the first calendar week or two of life, and a PICC line or peripheral Four later.
Monitoring equipment: All NICU patients are closely monitored. Micro preemies may have wired stickers on their chests, anxiety, wrists, arms, and legs. These are used to cheque blood pressure level, breathing rates, and oxygen levels in the blood.
NG/OG tube: Because micro preemies are as well immature to eat from a bottle or from the breast, a tube volition go from their mouths (OG tube) or noses (NG tube) into the stomach.

Micro Preemie Health Concerns

When a baby is born very prematurely, they are at risk for a number of wellness atmospheric condition. Some are brusque-term, while others may bear on them for the rest of their lives.

Curt-Term Health Concerns

Immediately after birth and during a micro preemie'south NICU stay, doctors and nurses watch closely for several serious medical atmospheric condition, such as these.

Intraventricular hemorrhage (IVH): IVH is bleeding into parts of the brain. Micro preemies have frail blood vessels in their brains, and these vessels tin rupture hands. About a quarter of micro preemies take serious IVH. Nearly cases of IVH resolve on their ain, but some babies may demand surgery to help drain the extra fluid.
Necrotizing enterocolitis (NEC): Since micro preemies accept young digestive systems, their intestines are susceptible to infection. In NEC, the linings of the bowels go infected and begin to die. In micro preemies, the condition tin can be extremely serious. NEC is treated with Four fluids and medication. Surgery may be required.
Patent ductus arteriosus (PDA): A PDA is a persistent connection between the big blood vessels most the heart. The connection is normal for a fetus but should close when a baby is built-in and begins to breathe. PDAs are treated with medication or surgery.
Respiratory distress syndrome (RDS): Most micro preemies take difficulty breathing after nascence. This syndrome is treated with respiratory support and medication.

Retinopathy of prematurity (ROP): The claret vessels in a micro preemie'due south eyes are not fully formed at nascency. When the vessels develop, they may grow so rapidly that they damage the retina. While some cases resolve on their own, surgery may be required in severe cases.
Sepsis: Premature babies are decumbent to infection for several reasons. Micro preemies have immature immune systems and face many invasive procedures in the NICU, each of which tin allow leaner to enter the body.

Long-Term Health Concerns

Many micro preemies prove no long-term effects of prematurity. However, other micro preemies may accept lifelong health issues.

Cognitive palsy: A portion of micro preemies accept moderate to astringent cerebral palsy.
Chronic lung illness: Many micro preemies need oxygen at NICU belch. Micro preemies may also have asthma or other respiratory bug, including bronchopulmonary dysplasia, or BPD.
Cognitive problems: Developmental delays, trouble in school, and other cognitive problems are common furnishings of prematurity.
Digestive problems: Micro preemies are prone to digestive problems such as gastroesophageal reflux disease (GERD), food refusal, or poor feeding.
Vision or hearing loss: A small pct of micro preemies have permanent vision or hearing problems due to complications of prematurity.

Survival Rate for Micro Preemies

Micro preemies are very fragile, and every day that they can spend inside the womb increases their hazard of survival.

Nascency Calendar week	Boilerplate Survival Rate
22 weeks	About 10% of babies survive
23 weeks	fifty% to 66% of babies survive
24 weeks	66% to 80% of babies survive
25 weeks	75% to 85% of babies survive
26 weeks	More than 90% of babies survive

Improve Your Baby's Chances

Although micro premies may confront serious health problems, there are many things that yous can practice every bit a parent to give your baby the best possible start.
