Epidural Volume Extension and Intrathecal Use of Local Anesthetics in Cesarean Sections

Phase 2
Conditions
Stillborn Caesarean Section
Interventions
Drug: Bupivacaine- Fentanyl - Normal Saline
Drug: Ropivacaine-Fentanyl-Normal Saline
Drug: Levobupivacaine- Fentanyl- Normal Saline
Registration Number
NCT01558713
Lead Sponsor
University of Patras
Brief Summary

Intrathecal (i.t.) administration of isobaric bupivacaine, ropivacaine and levobupivacaine with addition of fentanyl for c-section either combined or not with administration of 10 ml of N/S 0,9% epidurally, in order to extent epidural space.Sensory and motor block profile, haemodynamics and side effects were assessed.

Detailed Description

Parturients scheduled for elective caesarean section are randomly allocated to 6 groups: they receive double-blindly intrathecal isobaric bupivacaine 10 mg ( Group B), ropivacaine 15mg (Group R) , levobupivacaine 10mg (Group L) combined with 10 μg fentanyl and followed by epidural administration of 10 ml of N/S 0,9% respectively, and isobaric bupivacaine 10 mg ( Group BupivacaineF), ropivacaine 15mg (Group RopivacaineF) , and levobupivacaine 10mg (Group LevobupivacaineF) combined with 10 μg fentanyl without epidural administration of 10 ml of N/S 0,9%. Clinical endpoints are the sensory and motor block profile, haemodynamics (arterial pressure, heart rate) and side effects.

Primary Outcome Measures
NameTimeMethod
Dermatomes of Sensory blockup to 120 minutes average

Dermatomes of sensory block(pin prick test) are assessed every minute for the first 30 minutes after the intrathecal administration of local anesthetics and there after every 5 minutes until withdrawal of sensory block

Motor blockup to 120 minutes average

Motor block according to the Bromage scale are assessed every minute for the first 30 minutes after the intrathecal administration of local anesthetics and there after every 5 minutes until withdrawal motor block

Secondary Outcome Measures
NameTimeMethod
Arterial Blood Pressureup to 120 minutes average

Measurements assesed every minute within the first 30 minutes after the intrathecal administration of local anesthetics and every 5 minutes until withdrawal of sensory and motor block
