Brief summary

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.

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).

Inclusion criteria

* Woman over 18 years old undergoing caesarean section * She agrees to participate voluntarily. * She is already receiving any of the analgesic strategies studied.

Exclusion criteria

* 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

Design outcomes

Primary

MeasureTime frameDescription
