- Ages 18 to 50 years
- Women only
- Healthy volunteers accepted
- Adult
Study population: The target population of this study would correspond to women who underwent a caesarean section (therefore, of childbearing age) in the first 48 hours of their puerperium, who underwent surgery at the HUiP La Fe. Among these, the patients who, following the practice usual clinical presentation in a standard cesarean section at the study center, receive a TRON or an infusion through the epidural catheter with ropivacaine.
Who may be able to join
- Woman over 18 years old undergoing caesarean section
- She agrees to participate voluntarily.
- She is already receiving any of the analgesic strategies studied.
Who cannot join
- Receiving an analgesic medication other than the one mentioned as "routine multimodal analgesia" (either as regular medication or for acute post-surgical pain)
- Medical history that determines the baseline data of the scales and data that we collect ( pain or previous disabilities; addiction to drugs, alcohol or drugs; another disease that worsens the quality of life)
- Medical history that conditions the pharmacological effect (allergy, intolerance or atypical reaction to any of the drugs involved in its treatment or possible cross-reactions )
- Contraindication for neuraxial techniques (patient refusal, difficulty in understanding or communication, localized infection, increased intracranial pressure, or other medical criteria)
- Two or more previous caesarean sections
- Difficulty in understanding or communication
- Mother care will not be available to the newborn in the postpartum period for any reason

About this study
Official title: The Effect of Intravenous Infusion of Tramadol-ondansetron on Recovery After Caesarean Section. A Prospective, Observational and Non-inferiority Study Against Epidural Analgesia.
It will be a prospective observational cohort study. The investigators will compare post-cesarean section recovery in patients receiving intravenous infusion of tramadol-ondansetron versus epidural catheter with infusion of local anesthetics.
Read the detailed description
The primary outcome is to assess the non-inferiority in terms of post-cesarean section recovery of the intravenous perfusion of tramadol + ondansetron compared to the perfusion of local anesthetics through an epidural catheter.
This will be a prospective observational cohort study, with a total N of 312 patients who underwent a cesarean section. 156 who maintain the epidural catheter as the main measure of analgesia for 24 h, and 156 who receive an infusion of tramadol-ondansetron from the end of the cesarean section and for the following 24 h. The following data will be collected at 24 and 48 hours: need for unscheduled pharmacological reinforcement, adverse effects, QoR (Quality of Recovery) score 15, ObsQor-10 (Obstetric Quality of Recovery) score, and Visual Analogue Pain Scale (VAS) every 4 hours for 48 hours. The incidence of chronic pain 90 days after cesarean section will be assessed using the Numerical Pain Rating Scale (NRS).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Tramadol-ondansetron continuous infusionDrug
Analgesia strategy determined by routine use according to protocols, without investigator intervention.
Ropivacaine via epidural catheterDrug
Analgesia strategy determined by routine use according to protocols, without investigator intervention.
| Study group | Role | What they receive |
|---|---|---|
| TRON (Tramadol-Ondansetron) | Women who receive an infusion of tramadol-ondansetron from the end of the cesarean section and for the following 24 h. The infusion (TRON) is composed of 300 mg of tramadol and 12 mg of ondansetron dissolved in 250 ml of 0.9% saline, which is routinely programmed at 11 ml/h until the content is exhausted (approximately 23 hours). Receives: Drug: Tramadol-ondansetron continuous infusion | |
| AL-EPI (Local anesthetics via epidural) | Women who maintain the epidural catheter as the main measure of analgesia for 24 h. The epidural catheter after caesarean section is programmed with a 0.2% ropivacaine PCA (Patient controlled analgesia) pump at 7 ml/h with 7 ml on-demand boluses, with block every 20 min. Receives: Drug: Ropivacaine via epidural catheter |

Questions about this trial
What is this clinical trial studying?
An observational study of Post Operative Pain and Cesarean Section, run by Hospital Universitario La Fe at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Post-surgical recovery (time frame: Day 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05879536, which also lists 28 linked publications.
Does a listing mean the treatment is approved or proven to work?
