Clinical Trial Summary

This study evaluates the post-operative analgesic effects of quadratus lomborum block 2 and 3 (QLB 2, 3) in patients having cesarean section with spinal anesthesia. Spinal anesthesia will be performed to all patients for the surgery.

Description:

In this study, patients are divided into two groups. After the spinal anesthesia is performed and cesarean section surgery is over; QLB 2 block will be performed to patients in Group A ; while QLB 3 block will be performed to patients in Group B.

In addition, patient controlled analgesia (PCA) will be used in the first 24 hours postoperatively.

Group A - Patients in group A will have QLB 2 block after the surgery. In addition, patient controlled analgesia (PCA) will be used in the first 24 hours postoperatively.

Group B - Patients in group B will have QLB 3 block after the surgery. In addition, patient controlled analgesia (PCA) will be used in the first 24 hours postoperatively.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Opioid consumption in the first 24 hours after surgery	Morphine consumption in the first 24 hours will be counted by IV patient controlled analgesia device (PCA). Patients will be able to request opioids via PCA device when the nrs score is above 4.	1 day
Secondary	Post-operative acute pain	Pain status will be evaluated based on NRS scores. Pain status will be evaluated at 1, 3, 6, 9, 12, 18, 24. hours after surgery. Each NRS is scores 0-10. (0=no pain ; 10=pain as bad as can be)	1 day
