Spinal Anesthesia | Neonatal Spinal Anesthesia: Effects of the Addition of Clonidine

Spinal Anesthesia research study

What is the primary objective of this study?

This prospective, double blinded study investigates spinal anesthesia with or without clonidine added to bupivacaine in newborns. This study is based on duration measurement of spinal anesthesia and cardio respiratory recording during 24h for apnea detection.

Who is eligible to participate?

Inclusion Criteria: - Newborns less than 60 weeks old post-conceptional, former premature or not - Newborns requiring inguinal hernia or lower limbs surgery, - infants needing no more critical care assistance - Informed consent of parents Exclusion Criteria: - Spinal malformation, - Coagulopathy, - critical hemodynamics, - uncontrolled neurologic or metabolic pathology. - infection at injection point.

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Spinal Anesthesia


Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
