About this trial
This is an interventional treatment trial for Postoperative Pain
Eligibility Criteria
Inclusion Criteria:
- 18+ years of age.
- Scheduled for elective Caesarean Section in spinal anaesthesia.
- Have received thorough information, verbally and in written, and signed the "Informed Consent" form on participation in the trial.
Exclusion Criteria:
- Inability to cooperate

Outcomes
Primary Outcome Measures
Time to first opioid
The time from catheters placement to the administration of opioids
Secondary Outcome Measures
Pain intensity (NRS 0-10/10)
NRS (numeric rating scale) score in the study period at 3, 6, 9, 12 and 24 hours postoperatively. In addition, NRS score will be recorded electronically on all morphine administrations, since all patients must enter their NRS score on the Patient-Controlled Analgesia (PCA) pump display prior to administration of the PCA boluses. NRS is a pain scale where the patient gives her pain a number from 0-10, where 0 is no pain and 10 is the worst pain imaginable.
Total morphine consumption.
Morphine consumption at 3, 6, 9, 12 and 24 postoperative hours (data from PCA pump and patient medical record).
Catheter displacement.
Frequency of displacement of catheters (early displacement evaluated after 2 hours (T2), late displacement evaluated after 24 hours (T24)).
Patient satisfaction with application of the catheters.
NRS 0-10/10 during placement of catheters
The degree of morphine-related side effects (PONV, itching, fatigue, etc.).
On a scale from 0-3, where 0 is none, 1 is mild, 2 is moderate and 3 is severe.
Time from operation to ambulation.
Time from operation to ambulation.

5. Study Description
Brief Summary
The aim of this study is to investigate whether it is possible to prolong time to first opioid with the TQL block by inserting catheters bilaterally, providing continuous analgesia, in patients undergoing elective CS. Our hypothesis is that it will be possible to significantly extend time to first opioid with the blockade by 66.6%, increasing it from a mean of 5.6 hours to a mean of 10 hours.
