Insights

Smelling amniotic fluid significantly reduced pain in preterm infants during peripheral cannulation. This olfactory intervention offers a promising, non-invasive method to alleviate infant distress during medical procedures.

Area of Science:

  • Neonatal care
  • Pain management in neonates
  • Infant stress response

Background:

  • Peripheral cannulation is a common yet painful procedure for preterm infants.
  • Minimizing pain and stress is crucial for preterm infant well-being and development.
  • Non-pharmacological interventions are sought to manage procedural pain in neonates.

Purpose of the Study:

  • To evaluate the efficacy of olfactory stimulation with amniotic fluid in reducing pain and stress during peripheral cannulation in preterm infants.
  • To compare pain and stress levels between preterm infants exposed to amniotic fluid scent and those receiving routine care.

Main Methods:

  • Randomized controlled trial involving 61 preterm infants.
  • Intervention group: exposure to amniotic fluid scent for 15 minutes before, during, and after peripheral cannulation.
  • Control group: received routine care. Pain assessed using the Premature Infant Pain Profile (PIPP); stress assessed via salivary cortisol levels.

Main Results:

  • Infants in the amniotic fluid group experienced significantly lower pain scores during and after peripheral cannulation compared to the control group.
  • Salivary cortisol levels were lower in the amniotic fluid group post-procedure, though this difference was not statistically significant.
  • Baseline characteristics were similar between the two groups.

Conclusions:

  • Olfactory stimulation with amniotic fluid is an effective intervention for reducing pain in preterm infants undergoing peripheral cannulation.
  • This practice shows potential as a non-pharmacological method to manage procedural pain and stress in vulnerable neonates.
  • Further research may explore the impact on stress markers and long-term outcomes.
