Intrathecal morphine as sole analgesic during labour.

Area of Science:

• Obstetrics and Gynecology
• Anesthesiology
• Pain Management

Background:

• Labor pain management is crucial for maternal well-being.
• Traditional analgesics can have systemic side effects.
• Intrathecal drug delivery offers targeted pain relief.

Purpose of the Study:

• To evaluate the efficacy of subarachnoid morphine sulfate for labor pain relief.
• To assess maternal awareness and cooperation during labor and delivery.
• To determine the incidence and severity of side effects.

Main Methods:

• 12 consecutive unselected patients received a single 1.5 mg injection of subarachnoid morphine sulfate.
• Pain levels were assessed during the first and second stages of labor and early puerperium.
• Side effects were monitored and recorded.

Main Results:

• Complete pain abolition during the first stage of labor was achieved in all patients.
• Significant pain reduction or abolition was observed in the second stage and early puerperium.
• Mild side effects (itching, nausea, headache) were reported and easily managed.

Conclusions:

• Subarachnoid morphine sulfate is a highly effective analgesic for labor pain.
• It preserves maternal awareness and cooperation throughout labor and delivery.
• Further controlled trials are recommended to confirm these findings.
