An observational study in Cesarean Section, Postoperative Pain After Cesarean Section and Acute Pain, sponsored by Bursa City Hospital. Recruiting at 1 site in Turkey (Türkiye). Open to female participants aged 18 Years to 45 Years. Per ClinicalTrials.gov, last updated 2026-08-27.
Sponsored by Bursa City Hospital · Observational
This prospective observational study aims to identify predictors of severe postoperative pain during the first 24 hours after elective cesarean delivery under spinal anesthesia. Preoperative, intraoperative, and postoperative factors will be evaluated to determine their association with severe postoperative pain.
1,073 studies on the registry are indexed under Acute Pain; 166 are open to participants now.
This study's planned enrollment of 200 is above the median of 128 across 131 observational studies indexed under Acute Pain.

Women undergoing elective cesarean delivery under spinal anesthesia. Preoperative, intraoperative, and postoperative variables will be recorded to identify predictors of severe pain during the first 24 postoperative hours. All participants will receive routine clinical care without additional interventions.
Other: Observational Assessment of Postoperative Pain
Participants will receive routine spinal anesthesia and standard perioperative care for elective cesarean delivery. Preoperative, intraoperative, and postoperative variables will be recorded without any study-specific intervention.
Incidence of Severe Postoperative Pain
Severe postoperative pain will be defined as a Numerical Rating Scale score of 6 or higher. The scale ranges from 0 to 10, with higher scores indicating greater pain intensity.
Time frame: Within 24 hours after surgery
Preoperative Anxiety Score
Preoperative anxiety will be assessed using the Amsterdam Preoperative Anxiety and Information Scale anxiety subscale. Scores range from 4 to 20, with higher scores indicating greater anxiety.
Time frame: Before surgery
Preoperative Information Requirement Score
Information requirements will be assessed using the Amsterdam Preoperative Anxiety and Information Scale information subscale. Scores range from 2 to 10, with higher scores indicating greater information needs.
Time frame: Before surgery
Expected Postoperative Pain
Expected postoperative pain will be assessed using a Numerical Rating Scale ranging from 0 to 10, with higher scores indicating greater expected pain.
Time frame: Before surgery
Intraoperative Visceral Pain
The proportion of patients who experience visceral pain during cesarean delivery under spinal anesthesia will be recorded as a binary outcome (Yes/No).
Time frame: During surgery
Incidence of Intraoperative Shoulder Pain
The proportion of patients who experience shoulder pain during cesarean delivery under spinal anesthesia will be recorded as a binary outcome (Yes/No).
Time frame: During surgery
Incidence of Intraoperative Hypotension
The occurrence of hypotension during cesarean delivery under spinal anesthesia will be recorded.
Time frame: During surgery
Intraoperative Vasopressor Requirement
The requirement for vasopressor administration during cesarean delivery under spinal anesthesia will be recorded.
Time frame: During surgery
