Overview
A Preterm birth means a baby is born before they have completed 37 weeks of gestation. Preterm births are a leading cause of newborns suffering from complications and eventually dying. Early assessment of all risk factors, good prenatal care where appropriate, will greatly improve outcomes for both mom & baby.

1. Introduction.
To sum it up, preterm births, otherwise known as premature births, occur when a baby is born before the end of 37 weeks. Premature births occur when a mother delivers a baby prior to reaching the optimal time for delivery (37 weeks). Those babies tend to experience significant problems related to organ immaturity due to preterm birth. Due to the insufficient amount of time for organs to reach full maturity when born outside of the optimal time frame, premature babies face a watchful eye to help with monitoring for problems and provide supportive services as needed much sooner than full-term infants would.
2. Definition:
Birth of a baby that is less than 37 weeks
Leading reasons that newborns have complications
Most preterm births can be prevented with good prenatal care if you have risk factors or a history of premature deliveries.
Timely medical care will greatly reduce the impact of preterm birth on both the mother & baby.
3. Classification of Preterm Birth.
There are three classifications for preterm delivery. The classifications are based on the gestational ages of the infants (or the time when babies were born) and may be classified as:
1. Extremely preterm (<28 weeks).
2. Very preterm (28-32 weeks).
3. Moderately to late preterm (32-36 weeks).
Also, the shorter the length of gestation, the greater the risk of neonatal mortality and morbidity resulting from preterm delivery and any associated complications. As the gestation period increases (i.e., the length of time between last menstrual cycle (LMP) and date infant is born), risk of neonatal morbidity and mortality associated with preterm delivery and complications decreases.
4. Worldwide and Regionally, the Burden of Preterm Birth
Preterm birth is an ongoing global health problem, particularly in low and middle income nations. The World Health Organization states that it is also one of the main causes of death in children under 5 years of age.
- Developing nations have higher rates of prematurity.
- There are fewer neonatal care units to provide optimal care for preterm babies, creating more risk.
- Malnourished mothers are a significant contributor to preterm birth.
- Delayed access to antenatal healthcare also adversely affects outcomes.
5. Causes and Risk Factors for Preterm Birth.
Preterm birth is influenced by multiple factors, including maternal, fetal, and environmental influences. Identifying these factors early in pregnancy may aid in preventing preterm birth or managing when a preterm birth does occur.
5.1 Maternal Risk Factors.
The health of the mother is critical for a successful pregnancy. Chronic health conditions and infections place mothers at a greater risk of having preterm deliveries.
Prior preterm delivery.
- Hypertension, pre-eclampsia
- Gestational diabetes.
- Maternal infections such as urinary or sexually transmitted infections.
- Anemia.
- Malnutrition.
- Smoking and/or substance abuse.
- Maternal age extremes.
5.2 Fetal and Placenta Risk Factors.
The fetus must grow appropriately, and the placenta must be functioning normally, in order to maintain a pregnancy. Any abnormality (compromise) during growth and development can trigger preterm delivery.
- Intrauterine growth retardation.
- Placental insufficiency.
- Placenta previa or abruption.
- Reduced O2 supply.
5.3 Environmental and Lifestyle Risk Factors.
While there are many external (environmental) factors that affect pregnancy outcomes, many lifestyle choices also are linked with preterm birth. Chronic stress and inadequate prenatal care are major contributors.
- Chronic stress.
- Heavy physical labor.
- Inadequate prenatal care.
- Low socioeconomic status.
6. Signs To Look For That Indicate Premature Labor.
Identifying these symptoms promptly is essential in preventing possible complications. Symptoms can seem insignificant, but they warrant medical attention right away to avoid delivery complications.
- Frequent uterus contractions.
- Pain in the lower abdomen.
- Continuous lower or mid-back pain.
- Bleeding or fluid coming from the vagina.
- Frequent urination or incontinence.
7. Ways to Prevent Premature Labor:
Risk factors should be identified as early as possible, and proper care should be taken for the mother during her pregnancy to prevent complications. In many instances, even simple things that cost very little money can prevent complications from premature labor.
Prevention
- Early registration for maternity care.
- Routine antenatal visits.
- Testing for high-risk conditions.
- Changes in lifestyle.
- Eat a healthy diet and drink plenty of fluids.
- Get the proper amount of iron and folic acid.
- Get plenty of rest.
- Manage stress.
- Medical Interventions.
- Progesterone treatment (if indicated).
- Monitoring cervical length.
- Treating infections if present.
- The goal of management is to defer birth and ensure the best possible outcome for the fetus.
- Early intervention has been shown to reduce complications for newborns.
8. Management of Premature Labor:
- Antenatal Early Intervention
- Ultrasound exam
- Cervical assessment
- Risk stratification
- During Active Labor
- Medication used to delay contractions (tocolytics)
- Drugs to assist fetal lung maturity (corticosteroids)
- Drugs to treat infections (antibiotics)
- Medication to protect the brain of the fetus (magnesium sulfate)
9.Support for Neonates Born Prematurely:
Specialized healthcare providers are need to help a preterm baby survive and grow. Neonatal Intensive Care Units or NICU are there to help improve a baby's outcome.
- Respiratory Assistance
- Body Temperature Control
- Food Support
- Monitoring for Infections
- Problems Depending on Timing of Birth
- Preterm infants can have problems caused by both immediately after they are born and for a long time after they are born.
The severity of many of these problems will depend on how many weeks old the baby is when born and the type of medical care available to the baby after birth.
10. Problems in the Last Short Term.
10.1 Problems related to Pregnancy/Birthing
- Respiratory distress syndrome.
- Problems with feeding.
- Low body temperature.
- Infections.
10.2 Problems Long-term.
- Delayed development.
- Vision problems.
- Hearing problems.
- Chronic lung disease.
11. When to Seek Emergency Medical Help.
If you seek medical attention quickly after symptoms start, you have the best chance of preventing an ongoing and potentially serious health issue. Always pay attention to warning signs!
- Bleeding from the vagina before 37 weeks.
- Having regular contractions.
- Leakage of fluid from the vagina suddenly.
- Severe stomach cramps.
- Baby moving less than usual.
- Important Points.
Knowing about premature delivery will help to intervene early and improve outcomes. Therefore, awareness and prompt intervention represent the best way to intervene early and provide the best outcome.
12. Getting Medical Assistance:
Early antenatal care is vital
Many risk factors are preventable
Recognizing warning signs will save lives
Proper medical treatment will increase the chances of survival.
13. Some of the questions we often hear regarding premature delivery:
Q1. What are the major contributors to preterm delivery?
Answer.
In addition to numerous possible maternal health and infection causes, maternal health problems/infections can lead to preterm birth.
Some of these include:
- Maternal infections.
- Hypertension and/or diabetes.
- Prior preterm birth.
- Poor nutrition.
Q2.:Is it possible to stop preterm labor?
Answer.
Preterm labor can sometimes be delayed (not completely stopped), allowing the baby to be born later; and for steroids (to promote fetal lung development).
Medications can delay labor for 24-48 hours. However, not all women respond to treatment.
Q3. What are some of the first signs of labor?
Answer.
While the early symptoms of labor may be fairly mild, it is never appropriate to ignore these signs:
- Regular contractions
- Back pain or pressure in the pelvis
- Vaginal discharge and bleeding
- Fluid leaking from the vagina
Q4.What can be done to avoid preterm delivery?
Answer.
Proper prenatal care and following a healthy lifestyle can help lower the risk of preterm delivery:
- Routine prenatal care
- Eating a balanced diet plus taking prenatal vitamins
- Avoiding smoking or experiencing too much stress
- Getting enough sleep
Q5. Is preterm delivery dangerous for the infant?
Preterm deliveries may be dangerous for infants due to their incomplete organ development; however, there are improvements in modern medicine that will help improve infants’ chances of survival. Preterm infants are at risk for:
- Breathing issues
- Problems with feeding
- Increased risk of infection
- Inevitably delays in their development
Q6. What is the survival rate for preterm infants?
Answer.
The survival rate for preterm infants is determined by the gestational age of the preterm infant as well as the medical care available at the hospital.
- >32 weeks of gestation: the infant's survival rate is high
- 28-32 weeks of gestation: the infant's survival rate is moderate
- <28 weeks of gestation: the infant's survival rate is low.
- Preterm infants will need time in a NICU.
14. Final Thoughts.
Preterm delivery continues to be considered one of the most complex medical conditions, however; if diagnosed early and treated properly, preterm delivery can be managed effectively. Improving maternal health care services, making the public aware of the risk factors for preterm delivery and providing education about premature delivery will significantly reduce the incidence of preterm delivery and thereby improve survival of infants born prematurely.

15. Guidance for New Parents of Preterm Infants.
The responsibility of caring for a premature infant can be stressful for both parents and caregivers in the first few weeks of life, but with good direction, support from others, and appropriate health care, many parents will feel confident about providing for their child’s needs and improving their long-term health.
- Essential Recommendations for Care
- Follow Your NICU Discharge Instructions Exactly
- Be consistent with feeding times, administering medications, and attending follow-up visits.
- Be Sure to Provide Kangaroo Mother Care (Skin-to-Skin Contact)
- This will help to regulate your infant's temperature and breathing, as well as strengthen the bond between caregiver and infant.
- Use Strict Hygiene Practices
- To minimize the risk of infection in your infant with a suppressed immune system.
- Make Sure the Infant Gets Adequate Nutrition
- When possible, it is highly recommended that all premature infants receive breast milk (either by breastfeeding or using a breast pump).
- Regularly Monitor the Infant's Growth and Development
- Keep a record of your infant's weight gain, feeding habits, and developmental milestones to help determine if your infant is developing normally.
