Trial Outcomes & Findings for Intravenous Dexmedetomidine for Cesarean Section (NCT NCT03065530)
NCT ID: NCT03065530
Last Updated: 2020-01-13
Results Overview
visual analogue scale (VAS; with 0, no pain; to 10, the worst imaginable pain) is a validated assessing scale for pain intensity. VAS at rest was assessed when the patient was in supine position
COMPLETED
PHASE4
120 participants
6h after cesarean section.

Participant Flow
Parturients (\>18 and \<45 years old) with a singleton pregnancy admitted to our institute who underwent elective caesarean delivery under epidural anaesthesia were recruited in this study between February 2017 and October 2017.

SECONDARY outcome
Timeframe: 48h after cesarean section.Relative infant dose (RID) =Dose (infant, mg•kg-1•day-1) /Dose (mother, mg•kg-1•day-1) μg·kg-1·h-1. The Dose (infant) in mg•kg-1 is calculated by multiplying the concentration of the drug in breast milk by the volume of breast milk consumed daily (about 150 mL•kg-1).
