Melatonin As an Analgesic in Preterm Neonate

January 15, 2025 updated by: Ain Shams University

Efficacy of Melatonin As an Analgesic in Preterm Neonate

Melatonin (N-acetyl-5-methoxytryptamine) is a neurohormone secreted by the pineal gland with several important functions, including regulation of the circadian rhythms, antioxidant and anti-inflammatory effects, accumulating evidence revealed that it also plays an important role in pain modulation through multiple mechanisms. The investigators aimed to evaluate the analgesic effect of enteral melatonin given 30 minutes before cannula insertion in preterm neonates by assessing Premature Infant pain Profile score (PIPP) before and 5 minutes after the procedure. Additionally, the study aimed to explore the relationship between procedural pain and oxidative stress, along with the effectiveness of pain management of melatonin by measuring Malondialdehyde (MDA), a well-accepted marker of oxidative stress, 60 minutes after the procedure.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Malondialdehyde (MDA), marker of oxidative stress
Time Frame: 60 minutes of the procedure
Serum Malondialdehyde (MDA), a marker of oxidative stress through measuring serum MDA after 60 minutes of the procedure
60 minutes of the procedure
Evaluate the analgesic effect of melatonin in preterm
Time Frame: 5 minutes starting just before cannula insertion to 5 minutes after the procedure

Evaluate the analgesic effect of melatonin during venous cannula insertion in preterm neonates by assessing Premature Infant pain Profile score (PIPP) before and 5 minutes after the procedure.

Premature Infant pain Profile score (PIPP) scale 0-21, with 0-6 reflecting no pain, 6-12 reflecting mild-moderate pain, and above 12 indicating severe pain
5 minutes starting just before cannula insertion to 5 minutes after the procedure
