Registration Number
NCT04645823
Lead Sponsor
Women's Hospital HUS
Brief Summary

A total of 60 parturients undergoing induction of labour will be consented to participate in the study where they will be randomized to receive either spinal fentanyl (20 µg) or epidural analgesia (fentanyl 100µg and lidocaine 80 mg).

They will be monitored for the development of analgesia for a duration of 30 minutes.

GroupInterventionDescription
Spinal fentanylFentanyl CitrateUsing a combined spinal epidural technique a single dose of 20 µg of fentanyl diluted into 2 ml with NaCl 0.9 % will be injected into the CSF at lower lumbar interspace. An epidural catheter is left in place for subsequent analgesic doses.
Epidural lidocaine and fentanylLidocaine 1% Injectable SolutionUsing a catheter in the epidural space in the lower lumbar interspace a single dose of lidocaine (80 mg) and fentanyl (100 µg) is given. The epidural catheter is left in place for subsequent analgesic doses.

Primary Outcome Measures
NameTimeMethod
Analgesia at 20 minutes20 minutes

Reduction of visual analog scale (VAS) pain during contraction from pre-intervention value. 0 mm means no pain while 100 mm means worst possible pain.

Secondary Outcome Measures
NameTimeMethod
Pruritus0-30 minutes

The incidence of pruritus within 30 minutes after the intervention, graded: none, mild, moderate, severe, unbearable

Changes in the cardiotocography (fetal heart rate) within 30 minutes after the intervention0-30 minutes

Graded as normal, susceptible, pathological

Time until pain returns to 60 mm VAS30-180 minutes

Time from intervention until the maximum pain during contraction return to 60 mm on VAS scale

Ambulation during the analgesia provided by the intervention30-180 minutes

HAs the parturient been walking during the analgesia provided by the intervention

Use of oxytocin during the analgesia study period30 min

Oxytocin administered i.v. during 0-30 minutes after the analgesia (yes or no)

Cervical dilatation rate cm/h during the analgesia intervention0-180 min

(The cervical dilatation (1-10 cm) 1-3 hours post analgesia - The cervical dilatation (1-5 cm) before analgesia) / time between measurements (hours)

SAtisfaction of the parturient with the analgesia provided by the interventionat 30 minutes

On 0-100 mm visual analog scale (VAS). Where 0 means no satisfaction at all and 100 mm means maximum satisfaction.
