Pain Management During the First Stage of Labour

Nursing Tip: Always avoid the supine (flat on back) position to prevent maternal hypotension and hypoxemia. Use a wedge pillow or blanket to maintain a lateral tilt.

• Hydrotherapy: The use of warm showers, baths, or birth tubs can promote significant relaxation.
• TENS (Transcutaneous Electrical Nerve Stimulation): The application of electrical impulses via electrodes on the back to interfere with pain signaling.
• Acupressure: Applying pressure to specific points, such as the Ho-Ku point (the fleshy area between the thumb and index finger), may help enhance contractions without increasing pain.
• Intradermal Sterile Water Injections: A specialized technique where 0.1 mL of sterile water is injected into four specific locations on the lower back to relieve back pain.

Psychological and Cognitive Strategies

• Breathing Techniques: Controlled breathing helps the birther focus and manage the physiological response to contractions.
• Imagery and Visualization: Using focal points and mental imagery to redirect attention away from pain.
• Aromatherapy and Music: Sensory environmental controls used to promote a calm, relaxing atmosphere.

Pharmacological Interventions

When non-pharmacological methods are insufficient, pharmacological options can be introduced. The choice of medication depends on the stage of labour and the birther's preferences.

Systemic Analgesia

Systemic medications enter the bloodstream and affect the central nervous system.

• Nitrous Oxide (Laughing Gas): A 50/50 mix of oxygen and nitrous oxide administered via a mask. It has a rapid onset and termination, allowing the patient to remain alert and in control, though it may cause nausea or dizziness.
• Opioid Agonists (e.g., Morphine, Fentanyl): These provide systemic relief but can cross the placenta.

Clinical Alert: Because opioids can cause neonatal respiratory depression, Naloxone (Narcan) must be available for the newborn if respiratory depression is suspected.

Regional Anesthesia: The Epidural

The epidural is the most common and effective method for pain relief during the first stage of labour. It involves injecting a local anesthetic and/or an opioid into the epidural space via a catheter inserted near the lumbar vertebrae.

Key Considerations for Epidural Care:

1. Effectiveness: It can block pain and temperature transmission while often preserving motor function.
2. Risks: The most significant risk is maternal hypotension. Nurses must monitor blood pressure and fetal heart rate (FHR) frequently (e.g., every 2 minutes for 10 minutes after administration).
3. Nursing Role: Support the patient in a lateral position, monitor dermatome levels (the level at which sensation is blocked), and assess motor function before any ambulation.

Summary of Nursing Responsibilities

Regardless of the chosen method, the nurse's role is to continuously assess the effectiveness of the intervention, monitor both the birther and the fetus, and provide emotional support.
