A high-risk pregnancy is one where the mother, the unborn baby, or both face a significantly higher chance of health problems or death compared to a normal pregnancy. In Nigerian midwifery practice, recognizing these cases early during routine antenatal care is a primary duty. Common contributing factors in our local setting include extremes of maternal age, grand multiparity, severe anaemia, pre-existing medical conditions like hypertension and diabetes, and a history of previous obstetric complications such as ruptured uterus or repeated miscarriages.
Midwives working in primary health centres and tertiary hospitals must understand that risk status is dynamic. A woman who begins her pregnancy in a low-risk category can easily transition to high-risk due to new complications like gestational hypertension or intrauterine growth restriction. Early identification allows for prompt interventions, timely referrals, and ultimately, a reduction in our country's maternal and perinatal mortality statistics.
Triage is the process of rapidly sorting pregnant women upon arrival at the health facility based on the urgency and severity of their condition. In high-risk antenatal clinics, midwives use triage to separate stable routine attendees from those requiring immediate emergency intervention.
Key red flags that demand immediate medical attention include:
Managing high-risk pregnancies successfully is never a one-person job. It requires seamless collaboration among midwives, obstetricians, anaesthetists, paediatricians, and laboratory scientists. Midwives often act as the central coordinators of this team, monitoring the patient continuously and relaying vital changes to the medical doctors.
When a primary health centre encounters a complication beyond its capacity—such as severe pre-eclampsia or transverse lie—a prompt referral must be initiated. A proper referral requires three core components:
Surveillance involves the careful, ongoing monitoring of both the mother and the developing fetus to detect early signs of distress or worsening disease. For mothers with conditions like chronic hypertension or renal disease, routine checks include serial blood pressure measurements, urine protein assays, and baseline blood chemistry.
Fetal surveillance relies heavily on both clinical methods and advanced technology. Midwives routinely assess fetal growth using fundal height measurements and abdominal palpation. When complications arise, more specialized tests are employed:
Management plans for high-risk pregnancies depend entirely on the specific diagnosis, gestational age, and the well-being of mother and fetus. The primary goals are to prolong the pregnancy safely until fetal maturity is reached, or to effect a timely delivery if the intrauterine environment becomes hostile.
Medical management often involves administering targeted drugs, such as antihypertensives for severe blood pressure elevations, anticonvulsants like magnesium sulphate to prevent eclamptic seizures, and corticosteroids to speed up fetal lung maturation if preterm birth is expected. Surgical interventions may range from emergency cerclage placement for cervical incompetence to planned caesarean sections for placenta praevia. Throughout all interventions, continuous reassessment guides whether expectant management can continue or if delivery is urgently required.
Accurate, contemporaneous documentation is a legal and professional necessity in high-risk midwifery practice. Every assessment, triage decision, drug administration, and conversation with the patient or medical team must be recorded clearly in the case notes. Incomplete records compromise continuity of care and leave the midwife unprotected in medico-legal investigations.
Communication extends beyond paper records. Midwives must practice effective handover using structured formats such as SBAR (Situation, Background, Assessment, Recommendation) to prevent miscommunication during shift changes. Furthermore, midwives serve as crucial patient advocates. Many women in high-risk situations experience fear and confusion regarding complex medical procedures. Taking time to explain diagnoses in simple, local terms, respecting their cultural beliefs, and supporting their informed consent empowers women to participate actively in their own healthcare decisions.
