    Neonatal circumcision pain is reduced with penile nerve blocks. Local anesthesia significantly decreased physiologic stress and agitation in infants undergoing the procedure, with no adverse effects observed.

    Area of Science:

    • Neonatal care
    • Pediatric surgery
    • Pain management

    Background:

    • Neonatal circumcision is commonly performed without anesthesia or analgesia.
    • This procedure is associated with significant pain, crying, agitation, and physiological stress in infants.

    Purpose of the Study:

    • To evaluate the efficacy of penile nerve block using local anesthesia for pain and stress reduction during neonatal circumcision.

    Main Methods:

    • A comparative study involving 20 infants receiving a penile nerve block and 10 infants undergoing circumcision without anesthesia.
    • Physiological parameters including heart rate, blood pressure, and oxygen saturation were monitored.
    • Infant agitation and crying were also assessed.

    Main Results:

    Related Experiment Videos

    • Infants receiving the penile nerve block showed no significant changes in heart rate or blood pressure, unlike the unblocked group.
    • Oxygen saturation decline was significantly less in the anesthetized group (6%) compared to the unanesthetized group (16%).
    • Anesthetized infants exhibited reduced agitation and crying; lidocaine plasma levels were below toxic thresholds with no complications.

    Conclusions:

    • Penile nerve block with local anesthesia is a safe and effective method to reduce pain and physiological stress during neonatal circumcision.
    • This technique offers significant benefits for infant well-being during the procedure.
    • Routine use of local anesthesia should be considered for neonatal circumcision.
