Official title
Randomized Trial Comparing the Injection of Intrathecal Fentanyl Versus Epidural Fentanyl for the Initiation of Labour Analgesia on the Incidence of Pruritis.
Overview
The purpose of this study is to investigate the effect of neuraxial analgesia initiation on the incidence of pruritus in laboring women. Specifically, this study aim to compare intrathecal fentanyl with epidural fentanyl in order to determine whether the epidural route is associated with a lower occurrence and severity of pruritus. By clarifying these differences, the research seek to optimize analgesic strategies during labor while minimizing opioid-related side effects
Interventions
- Procedure Spinal analgesia
All procedures performed will be standardized. When neuraxial analgesia is required, an non-implicated anesthesiologist will performe the technique (not blind) The procedure will involve two steps. The first will involve an intraspinal injection of the solution using a 25-gauge Whitacre needle, while the second will be administered through the epidural catheter. STEP 1: Intraspinal SPINAL Group: Bupivacaine 0.25% Isobaric 1 ml + Fentanyl 15 mcg, (0,3ml) STEP 2: Epidural SPINAL group: 0.9% NaCl - Procedure Epidural Analgesia

STEP 1: Intraspinal EPI Group: Bupivacaine 0.25% Isobaric 1 ml + NaCl 0.9% 0.3 ml STEP 2: Epidural EPI group: Fentanyl 100 mcg, (2 ml
Primary outcome measures
- Pruritus [Time frame: Every 15 minutes for the first hour, then every 30min for 2 hours until neuraxial analgesia]
Secondary outcome measures (5)
- Nausea Vomiting [Time frame: 2 hours until neuraxial analgesia]
- Hypotension [Time frame: 2 hours until neuraxial analgesia]
- Urinary rentention [Time frame: 24 hours until the neuraxial analgesia]
- Maternal satisfaction [Time frame: 24 hours until neuraxial analgesia]
- Fetal Bradycardia [Time frame: 2 hours until neuraxial analgesia]
