Labour is an intense and transformative experience, but it doesn’t always go according to plan. When complications arise during delivery, quick recognition and skilled intervention can make all the difference for both mother and baby. Understanding how healthcare teams manage issues like fetal distress, prolonged labour, and pre-eclampsia helps nursing professionals provide safer, more effective care during this critical time.

Recognizing and managing fetal distress
Fetal distress occurs when a baby isn’t receiving adequate oxygen during labour. Healthcare providers primarily detect this through continuous electronic fetal heart rate monitoring, which tracks patterns that may indicate the baby is in trouble. An abnormal heart rate pattern doesn’t always mean the baby is in danger, but it signals the need for immediate evaluation and possible intervention.
When fetal distress is suspected, the first response involves a series of measures called intrauterine fetal resuscitation. These techniques aim to improve oxygen delivery to the baby while healthcare teams decide on the next steps. The approach includes repositioning the mother to the left lateral position, which relieves pressure on major blood vessels and improves blood flow to the placenta. If that doesn’t help, trying the right lateral or knee-elbow position may provide relief.
Immediate intervention strategies
Beyond repositioning, several other measures can help stabilize a distressed baby. Administering high-flow oxygen to the mother increases oxygen availability for the baby, though this should be done carefully and for limited periods. If uterine contractions are too frequent or intense, stopping oxytocin infusions or giving tocolytic medications like terbutaline can reduce contraction frequency and improve placental blood flow.
Rapid intravenous fluid administration is another key intervention. Giving one liter of crystalloid solution quickly can improve maternal blood pressure and uterine blood flow, even when the mother’s blood pressure appears normal. For mothers with low amniotic fluid, amnioinfusion-infusing warm saline into the uterine cavity-can relieve cord compression and improve fetal heart rate patterns.
These resuscitation measures buy valuable time. They may allow labour to continue safely or improve the baby’s condition before an emergency cesarean delivery becomes necessary. The key is acting quickly when monitoring shows concerning patterns while avoiding unnecessary interventions when the baby is coping well with labour.
Addressing prolonged labour
Prolonged labour, also called failure to progress, happens when labour moves too slowly or stalls entirely. This complication affects about 8% of people giving birth but accounts for roughly one-third of all cesarean deliveries. The condition can occur during either the first stage, when the cervix dilates, or the second stage, when the baby moves through the birth canal.
Labour is considered prolonged when it lasts more than 25 hours for a first baby or 20 hours for subsequent births. During the first stage, prolonged labour usually means the cervix has stopped dilating before reaching the necessary 10 centimeters. Common causes include inefficient uterine contractions, a baby that’s too large for the pelvis, or an incorrectly positioned baby.
Risks and complications
The implications of prolonged labour differ depending on which stage is affected. During the first stage, the main concerns are maternal exhaustion and psychological distress. However, prolonged second stage labour carries more serious risks. These include increased risk of infection, postpartum hemorrhage, and potential long-term issues like incontinence or pelvic organ prolapse.
For babies, prolonged labour can lead to several complications. Oxygen deprivation becomes more likely as labour extends, potentially causing fetal distress. Babies may develop birth injuries including shoulder dystocia, where they become stuck in the birth canal, or more serious conditions like hypoxic ischemic encephalopathy, a brain injury caused by insufficient oxygen.
Management approaches
Managing prolonged labour requires balancing patience with timely intervention. During the first stage, healthcare providers may recommend breaking the amniotic sac (amniotomy) to encourage stronger contractions. Medications like oxytocin can strengthen and regularize contractions when they’re weak or irregular. Sometimes, simple measures like changing positions, walking, or resting can help labour progress.
When prolonged labour occurs during the second stage, management depends on how far the baby has descended. If the baby is in the birth canal but delivery isn’t progressing, assisted delivery with forceps or vacuum extraction may be necessary. When these methods aren’t appropriate or when either mother or baby shows signs of distress, emergency cesarean delivery becomes the safest option.
Managing pre-eclampsia during labour
Pre-eclampsia is a serious pregnancy complication characterized by high blood pressure and signs of organ damage, typically affecting the kidneys. While it usually develops during pregnancy, about 24% of pre-eclampsia cases have their onset during labour itself. Managing this condition during delivery requires careful monitoring and prompt medical intervention.
The primary treatment for pre-eclampsia is delivery of the baby, as this is the only way to completely resolve the condition. However, timing and method of delivery depend on disease severity and gestational age. For severe pre-eclampsia, labour may need to be induced immediately to prevent life-threatening complications.
Medication management during delivery
Several medications play crucial roles in managing pre-eclampsia during labour. Magnesium sulfate is administered intravenously to prevent seizures, which are a major risk when pre-eclampsia progresses to eclampsia. Healthcare teams monitor knee reflexes closely during magnesium therapy, as loss of these reflexes can indicate dangerous magnesium levels.
Blood pressure control is another priority. Medications like nifedipine or hydralazine are used to gradually lower blood pressure, reducing the risk of stroke and other cardiovascular complications. The goal isn’t to normalize blood pressure immediately but to bring it down to a safer range that protects both mother and baby.
Delivery considerations
Most women with pre-eclampsia can deliver vaginally if the condition is well-controlled. For most pregnant people with pre-eclampsia, it’s safe to have an epidural for pain management as long as blood test results are normal. However, women with very low platelet counts may not be candidates for epidural anesthesia due to bleeding risks.
The early third stage of labour-immediately after the baby is born-requires special attention in pre-eclampsia cases. Blood pressure can fluctuate significantly during this period, and the risk of postpartum hemorrhage may be elevated. Continuous monitoring and having emergency medications readily available are essential components of safe care.
The role of the healthcare team
Managing labour complications effectively requires coordination among multiple healthcare professionals. Obstetricians, midwives, nurses, and anesthesiologists each bring specialized knowledge to address different aspects of care. Nurses play a particularly vital role in continuous monitoring, early detection of problems, and supporting mothers and families through challenging situations.
Clear communication within the team is essential. When fetal heart rate patterns change or a mother’s blood pressure spikes, every team member needs to understand the situation and their role in the response. Standardized protocols and regular training in emergency procedures help ensure quick, coordinated action when complications arise.
Documentation throughout labour provides crucial information for decision-making. Tracking contraction patterns, cervical dilation, fetal heart rate changes, and maternal vital signs creates a clear picture of how labour is progressing and when intervention might be needed.
What do you think? How might better understanding of these complications change the way nurses approach labour monitoring? What challenges might healthcare teams face when deciding between conservative management and immediate intervention?
