Labor Pain, Induced; Birth
Conditions
Keywords
epidural analgesia, spinal analgesia, labor pain
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.
Interventions
Fentanyl citrate 20 µg in 2 ml of saline injected into csf
Fentanyl citrate 100µg and lidocaine hydrochloride 80 mg in 10 ml volume

Study design
Masking description
The parturient and the midwife as well as the researcher doing the interview for analgesia will be masked. The anesthesiologist performing either spinal fentanyl administration or epidural analgesia will not be masked
Intervention model description
60 parturients randomized to two different treatment arms (30 in each group)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Analgesia at 20 minutes | 20 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
| Measure | Time frame | Description |
|---|---|---|
| Ambulation during the analgesia provided by the intervention | 30-180 minutes | HAs the parturient been walking during the analgesia provided by the intervention |
| Changes in the cardiotocography (fetal heart rate) within 30 minutes after the intervention | 0-30 minutes | Graded as normal, susceptible, pathological |
| Pruritus | 0-30 minutes | The incidence of pruritus within 30 minutes after the intervention, graded: none, mild, moderate, severe, unbearable |
| Time until pain returns to 60 mm VAS | 30-180 minutes | Time from intervention until the maximum pain during contraction return to 60 mm on VAS scale |
| Cervical dilatation rate cm/h during the analgesia intervention | 0-180 min | (The cervical dilatation (1-10 cm) 1-3 hours post analgesia - The cervical dilatation (1-5 cm) before analgesia) / time between measurements (hours) |
| Use of oxytocin during the analgesia study period | 30 min | Oxytocin administered i.v. during 0-30 minutes after the analgesia (yes or no) |
| SAtisfaction of the parturient with the analgesia provided by the intervention | at 30 minutes | On 0-100 mm visual analog scale (VAS). Where 0 means no satisfaction at all and 100 mm means maximum satisfaction. |
