Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Cumulative opioid consumption within 48 hours after surgery, expressed as oral morphine equivalents (OME) | From the end of surgery to 48 hours after surgery | Cumulative amount of opioid consumed from the end of surgery through 48 hours postoperatively, expressed as oral morphine equivalents (mg OME). Only sufentanil delivered by the patient-controlled intravenous analgesia device is counted and is converted to OME using standard equianalgesic conversion tables. Intravenous flurbiprofen axetil given as rescue analgesia is a non-opioid and is not counted. Any additional opioid administered during or after surgery is converted and included in the total. |
| Secondary | Area under the curve (AUC) of resting pain NRS scores from 0 to 48 hours after surgery | 0 to 48 hours after surgery | Area under the curve of resting pain intensity calculated by the trapezoidal rule from numerical rating scale (NRS, 0 to 10) scores recorded at 2, 6, 12, 24 and 48 hours after surgery. Higher values indicate greater cumulative pain intensity. |
| Secondary | Resting, movement-evoked and visceral pain NRS scores | 2, 6, 12, 24, 48 and 72 hours after surgery | Pain intensity assessed with an 11-point numerical rating scale (NRS, 0 = no pain, 10 = worst imaginable pain) at rest, on movement (turning in bed, coughing) and as visceral pain (deep dull or dragging pain arising from the renal capsule and ureteric stent). Resting and movement-evoked pain are assessed at 2, 6, 12, 24, 48 and 72 hours; visceral pain is assessed at 6, 12, 24 and 48 hours. |
| Secondary | Time to first request for rescue analgesia | From completion of the block procedure to 72 hours after surgery | Time from completion of the block procedure to the first request for rescue analgesia, used as a surrogate measure of the duration of analgesia. |
| Secondary | Onset time and dermatomal extent of sensory block | 30 minutes after the block procedure; 24 hours after surgery | Onset time is the interval from injection of local anaesthetic to a demonstrable reduction in cold sensation, assessed 30 minutes after the block in the awake participant. The dermatomal extent of sensory block is mapped once at 24 hours after surgery using cold stimulation and is recorded as the blocked dermatomal levels. |
| Secondary | Incidence of adverse events | From the block procedure through 72 hours after surgery | Occurrence of postoperative nausea and vomiting, puncture-related complications (haematoma, pneumothorax, infection), systemic local anaesthetic toxicity and non-steroidal anti-inflammatory drug-related adverse reactions (gastrointestinal discomfort, bleeding). Timing, severity, management and outcome are recorded for each event. |
| Secondary | Patient satisfaction with postoperative analgesia | Before hospital discharge, an average of 3 days after surgery | Satisfaction with postoperative pain treatment assessed before discharge using a 5-point Likert scale (very dissatisfied, dissatisfied, neutral, satisfied, very satisfied). |
