Dexmedetomidine Versus Fentanyl for Sedation of Postoperative Mechanically Ventilated Neonates

Phase 2
Completed
Conditions
Postoperative Pain
Interventions
Registration Number
NCT05324891
Lead Sponsor
Mansoura University
Brief Summary

Newborn infants experience pain after surgical procedures,prevention and management of pain in neonates is important due to its deleterious consequences. Fentanyl is a widely used analgesic which promotes rapid analgesia,however, is not free of adverse effects including chest wall rigidity, hypothermia, hypotension, respiratory depression and tolerance.Dexmedetomidine is a selective α 2-adrenergic agonist can cause sedation, anxiolysis, analgesia and minimal respiratory depression.Therefore, the objective of the study is to evaluate the safety and efficacy of dexmedetomidine compared to fentanyl in postoperative mechanically ventilated neonates.

Detailed Description

A prospective, randomized trial, which was conducted upon neonates who needed postoperative mechanical ventilation in Neonatal Intensive Care Unit, Mansoura University Children's Hospital.The patients were randomized to two groups according to the drug they received for postoperative sedation. The first group received dexmedetomidine infusion and the second group received fentanyl infusion.Our primary outcome was the efficacy of postoperative sedation score, and the secondary outcomes were plasma cortisol level, time to extubation, time to reach 100ml/kg enteral feed, need for adjuvant sedative and skeletal muscle relaxant, length of the hospital stay, side effects of sedative drugs and mortality.

Primary Outcome Measures
NameTimeMethod
The efficacy of postoperative sedation according to pain score.upto five days after surgical intervention

Assessment of Neonatal Pain, Agitation and Sedation Scale immediately after the operations then every 12 hours till 5 days

Secondary Outcome Measures
NameTimeMethod
Plasma cortisol levelWithin 48 hours after surgical intervention

Plasma as a base line after the operation and another two measures one after 24 hours from the operation and the other after 48 hours

Need of adjuvant analgesics or sedativesupto five days after surgical intervention

Infants in both groups received open-label intravenous fentanyl boluses at a dose of 1µg/kg, as adjuvant analgesic when the pain score was more than 3 points. The dose was repeated, based on pain score assessment, at a minimum interval of 2-4 hours. Also, both groups received midazolam bolus at a dose of 0.1 mg/ kg/dose IV as adjuvant sedative in both groups when the patient was agitated.

Need of skeletal muscle relaxantupto five days after surgical intervention

Neonates in both groups received Pancuronium at a dose of 0.1 mg/ kg /dose IV as a skeletal muscle relaxant when two boluses of midazolam failed to control agitation

Time to extubation.upto 21 days postoperative

Days upon mechanical ventilation

Length of hospital stay.upto 30 days postoperative

Days of hospital admission

Mortalityupto 21 days postoperative

Death

Adverse effects of the sedative drugsupto seven days after surgical intervention

Hypotension, bradycardia, chest wall rigidity, feeding intolerance withdrawal signs,re-intubation within 48 hours

Time to reach 100ml/kg/day enteral feed.upto 21 days postoperative

Days to reach 100ml/kg/day enteral feed.

Culture-proven sepsisupto 30 days after surgical intervention
