Preterm Labour Causes and Risk Factors

Preterm Labour

Causes And Risk Factors

• Infection: Urinary tract infections and certain reproductive infections can trigger preterm labour.
• Multiple pregnancies: Carrying twins, triplets, or more increases the risk.
• Previous preterm births: History of preterm delivery significantly raises risk.
• Chronic health issues: Conditions like diabetes, hypertension, and obesity can contribute.
• Cervical or uterine abnormalities: Structural issues can lead to premature contractions.
• Lifestyle factors: Smoking, excessive alcohol use, and illicit drug use are linked to higher risk.
• Age: Women younger than 17 or older than 35 are at increased risk.
• Stress: High levels of physical or emotional stress can trigger preterm labour.

Preventive Measures

• Regular prenatal care: Early and consistent check-ups can help identify risks.
• Avoidance of smoking and drugs: Reducing or eliminating these substances is crucial.
• Managing chronic conditions: Proper management of diabetes and hypertension can lower risk.
• Nutrition and hydration: A balanced diet and adequate hydration support pregnancy health.
• Limit physical exertion: Avoiding strenuous activities may help reduce triggers.
• Stress management techniques: Practices like mindfulness, yoga, or counseling can be beneficial.

Long-term Effects On Infants

• Respiratory issues: Increased risk of bronchopulmonary dysplasia and asthma.
• Neurological problems: Higher likelihood of cerebral palsy and developmental delays.
• Vision impairments: Risks for retinopathy of prematurity.
• Feeding difficulties: Many preterm infants face challenges with breastfeeding or bottle feeding.
• Behavioral issues: Potential for increased anxiety, ADHD, and learning difficulties in childhood.

Management And Treatment

• Medications:
  • Tocolytics to delay labour.
  • Corticosteroids to promote fetal lung maturity.
• Hospitalization: Monitoring for signs of preterm labour may necessitate in-hospital care.
• Cervical cerclage: Surgical procedure to reinforce the cervix in high-risk women.
• Bed rest: Often recommended to reduce physical stress on the body.
• Hydration: Maintaining fluid intake can help with uterine contractions.

Symptoms And Diagnosis

• Symptoms:
  • Regular contractions or cramping before 37 weeks.
  • Change in vaginal discharge (increased or blood-tinged).
  • Lower back pain or pelvic pressure.
  • Abdominal pressure or discomfort.
• Diagnosis:
  • Physical exam to assess contractions.
  • Ultrasound to evaluate cervical length and fetal condition.
  • Fetal monitoring techniques to track heart rate and movement.
  • Testing for infection if suspected as a cause.

Preterm Labour Causes

• Infections like urinary tract infections and reproductive infections can trigger preterm birth.
• Multiple pregnancies (twins, triplets, etc.) significantly increase risk.
• History of preterm birth makes future pregnancies more likely to be premature.
• Chronic health conditions like diabetes, hypertension, and obesity increase risk.
• Cervical or uterine abnormalities can lead to premature contractions.
• Lifestyle factors like smoking, excessive alcohol use, and drug use are linked to higher risk.
• Age - women under 17 or over 35 are at increased risk.
• Stress - High levels physical and emotional stress can trigger preterm labor.

Preterm Labour Prevention

• Regular prenatal care can help identify risks and provide early intervention.
• Avoidance of smoking and drugs is crucial to lower risk.
• Management of chronic conditions like diabetes and hypertension is essential for healthy pregnancies.
• Nutrition and hydration through a balanced diet and adequate water intake support pregnancy health.
• Limited physical exertion by avoiding strenuous activities can reduce risk.
• Stress management techniques like mindfulness, yoga, or counseling can benefit pregnant women.

Preterm Labour Long-term Effects On Infants

• Increased risk of respiratory issues like bronchopulmonary dysplasia and asthma.
• Higher likelihood of neurological problems like cerebral palsy and developmental delays.
• Vision impairments like retinopathy of prematurity are more likely.
• Feeding difficulties including breastfeeding or bottle feeding problems are common in preterm infants.
• Behavioral issues like anxiety, ADHD, or learning difficulties may be more prevalent in childhood for these babies.

Preterm Labour Management and Treatment

• Medications are used to treat preterm labour including:
  • Tocolytics to delay labour.
  • Corticosteroids to promote fetal lung maturity.
• Hospitalization may be necessary to monitor preterm labour symptoms.
• Cervical cerclage, a surgical procedure to reinforce the cervix, is used for high-risk women.
• Bed rest is often recommended to reduce physical stress.
• Hydration through maintaining fluid intake is important to help regulate uterine contractions.

Preterm Labour Symptoms and Diagnosis

• Symptoms of preterm labour include:
  • Regular contractions or cramping before 37 weeks.
  • Changes in vaginal discharge (increased or blood-tinged).
  • Lower back pain or pelvic pressure.
  • Abdominal pressure or discomfort.
• Diagnosis involves:
  • Physical exam to assess contractions.
  • Ultrasound to evaluate cervical length and fetal condition.
  • Fetal monitoring techniques to track heart rate and movement.
