Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: 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, and that bilateral TQL catheters will significantly reduce the Numerical Rating Scale (NRS) pain score (0-10/10) compared to the placebo group.;Secondary Objective: Not applicable;Primary end point(s): Time to first opioid.;Timepoint(s) of evaluation of this end point: 24 hours postoperative | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): (A) Pain intensity (NRS 0-10/10) 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. (B) Total morphine consumption. Morphine consumption at 3, 6, 9, 12 and 24 postoperative hours (data from PCA pump and patient medical record). (C) Frequency of displacement of catheters (early displacement evaluated after 2 hours (T2), late displacement evaluated after 24 hours (T24)). (D) Patient satisfaction with application of the catheters. (E) The degree of morphine-related side effects (PONV, itching, fatigue, etc.). (F) Time from operation to ambulation.;Timepoint(s) of evaluation of this end point: 24 hours postoperative | — |
