About this study
Official title: Evaluation of the Effect of Postoperative Analgesia Techniques on Obstetric Recovery Quality With ObsQoR-10
The primary objective of this study is to evaluate the effects of postoperative analgesia techniques-transversus abdominis plane (TAP) block and wound infiltration-on recovery in patients undergoing elective cesarean section, using the Obstetric Quality of Recovery-10 (ObsQoR-10) questionnaire. The secondary objective is to assess pain scores, analgesic consumption, and adverse effects such as nausea, vomiting, and pruritus within the first 24 hours postoperatively.
Read the detailed description
The patients will be divided into 3 groups as Group T (transversus abdominis plane block), Group W (wound infiltration) and Group K (control). All of them will be given spinal anesthesia in sitting position.Group C will receive spinal anesthesia. In Group T (Transversus abdominis plane block) cases, in addition to spinal anesthesia at the end of the surgery, 20 ml of 0.25% bupivacaine will be applied bilaterally between the transversus abdominis muscle and the internal oblique muscle. Group WI (wound infiltration) will be administered 20 ml 0.25% bupivacaine to the wound area in addition to spinal anesthesia at the end of the surgery.Numerical pain scores (NRS Resting and Movement), heart rate, mean arterial pressure, peripheral oxygen saturation, analgesic consumption, nausea and vomiting score, pruritus, Ramsey sedation scale and other postoperative complications will be recorded at the 2nd hour, 6th hour, 12th hour and 24th hour postoperatively .Obstetric Quality of Recovery -ObsQoR-10 questionnaire will be applied to the patients at the end of 24 hours.

What is being measured
The primary outcome is the main question the study is designed to answer.
Obstetric Quality of Recovery-10
The ObsQoR-10 questionnaire consists of 10 questions that assess the patient-reported quality of recovery in obstetric patients' postoperative period using an 11-point scale (0 = strongly negative; 10 = strongly positive) that points to a minimum score of 0 (worst possible recovery) and a maximum score of 100 (best possible recovery).
Measured: At postoperative 24th hours
Secondary outcomes (1)
Postoperative pain score, analgesic consumption
Numeric rating scale pain from 0 (no pain) to 10 (worst pain).
Measured: At postoperative 24 hours (0, 2, 6,12,24)

Questions about this trial
What is this clinical trial studying?
A study testing Group C, Group T and Group W in people with Pain, Postoperative and Postoperative Complications, run by Eskisehir Osmangazi University at 1 site in Turkey (Türkiye).
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 1 inclusion and 6 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 18 May 2026. 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 Turkey (Türkiye). 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?
Obstetric Quality of Recovery-10 (time frame: At postoperative 24th hours). 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 NCT06978491, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
