The partograph is a critical pictorial and graphic summary of established labour recorded on a single sheet of paper. It provides a continuous, at-a-glance clinical overview of the progress of labour and the condition of both mother and foetus. Originating from WHO recommendations, its primary goal is to prevent prolonged labour and reduce maternal and perinatal morbidity and mortality. In busy clinical settings across Nigeria, from primary health centres to tertiary teaching hospitals, this tool serves as an early warning system. It alerts midwives and obstetric nurses to deviations from normal progress, allowing timely interventions or referrals before complications escalate into emergencies.
Using a partograph transforms labour management from guesswork to objective observation. It reduces unnecessary interventions like routine inductions or augmentations while ensuring that genuine delays are managed promptly.
The standard WHO partograph is divided into distinct sections that capture every vital parameter during the active phase of labour. Understanding how these sections interlock is essential for accurate documentation.
| Section | Primary Parameters Recorded | Timing / Frequency |
|---|---|---|
| Foetal Condition | Heart rate, liquor state, moulding | Every 30 minutes to 1 hour |
| Progress of Labour | Cervical dilation, descent, contractions | Every 4 hours (dilation), half-hourly (contractions) |
| Maternal Condition | Pulse, blood pressure, temperature, urine | BP every 4 hours, pulse hourly, urine passed |
| Drugs and Fluids | Oxytocin, IV fluids, medications given | As administered |
Monitoring the unborn baby ensures that the stress of uterine contractions is well tolerated.
Tracking how quickly the cervix opens and how far the baby descends prevents prolonged obstructed labour. Cervical dilation is plotted on the vertical axis against time on the horizontal axis. In active labour, the cervix should dilate at least 1 cm per hour. Uterine contractions are also tracked in this section by counting how many contractions occur in a 10-minute window and noting their duration in seconds, represented by shading grid squares.
Maternal physiological stability directly impacts foetal wellbeing. Nurses must regularly check and record blood pressure every four hours and pulse every half-hour to hourly. Temperature is recorded every four hours to catch early signs of chorioamnionitis. Urine output, volume, and the presence of protein or acetone must be assessed and documented. Medications, intravenous fluids, and oxytocin drips are logged precisely to track fluid balance and pharmacological interventions.
The alert line starts at 4 cm of cervical dilation and travels upwards and to the right at a rate of 1 cm per hour. When the plotting of cervical dilation crosses the alert line, it warns the nurse that labour is slower than normal and the patient must be transferred to a comprehensive emergency care facility if managed at a primary level. The action line is parallel, drawn four hours to the right of the alert line. Crossing the action line demands immediate medical intervention, re-evaluation, and definitive management such as augmentation or Caesarean section.
Accurate partograph completion is a core professional duty for midwifery and nursing students. Documentation must happen in real time, not from memory hours later. Nurses are responsible for interpreting the graphic trends, recognizing abnormal patterns such as prolonged latent phase or secondary arrest of dilation, and initiating prompt referrals. Collaborative communication with doctors ensures that when lines are crossed, clinical action occurs swiftly to safeguard mother and child.
