Background and Aims It is aimed to compare the effect of three different analgesic techniques used for pain control after elective cesarean section operations on quality of recovery as stated by the patient, using the ObsQoR-10 scoring system.

Methods 30 women scheduled for cesarean section under spinal anaesthesia were randomly allocated into three groups. Spinal anaesthesia was maintained with 11.2 mg hyperbaric bupivacaine+15 µg fentanyl in Groups II-III, while morphine was also added in Group I. In Group II, bilateral ultrasound-guided QLB-I was performed and in Group III the same volume and concentration of anaesthetic was instilled on uterus, infiltrated on rectus aponeurosis and through the wound site. The patients filled out ObsQoR-10 and EuroQol 5-dimension 3L at 24 hours postoperatively.

Results Validity was evaluated by hypothesis test and structural validity. There was no difference considering ObsQoR-10 scores at 24 hours postoperatively between the groups. Scores were in correlation with age, ambulation time, passive and active pain scores at 24 hours. ObsQoR-10 values were found to be lower in those treated with ondansetrone and who had nausea and vomiting. (p<0.05). There was a moderate correlation of ObsQoR-10 score with EuroQol 5-dimension 3L scores (r=- 0.690). The ObsQoR-10 is found to be consistent internally and has excellent test-retest reliability. The highest ranked items were, nausea or vomiting, dizziness, shivering, and lowest was pain. (NCT06341049)

Conclusions In this study, it was found that groups had no difference in terms of ObsQoR-10 scores and that this scoring sytem is a valid and reliable tool to evaluate pain recovery.
