Outcome
|
Timepoint(s) at which outcome measured
|
Primary Outcome |
Time in minutes to 1st request of rescue analgesia in PACU and defined by pain score ˃4/10. |
started 15 min after extubation |
Secondary Outcome |
Pain score assessed by Wong-Baker Faces Scale . Score ranges from 0 to 10
with 0 means no pain and 10 means worst pain imaginable. |
at the following intervals: 15, 30, 45 and 60 min, 6, and 12 hours after surgery post-extubation |
Secondary Outcome |
Block failure rate where the block was considered a failed block when the patient required more than two doses of rescue analgesia in the first hour postoperatively. |
during the 1st hour post-extubation |
Secondary Outcome |
Number of doses of rescue analgesia |
post-extubation up to 60 min postoperatively |
Secondary Outcome |
Onset and incidence of complications, such as:
- Intraoperative bradycardia (decrease in heart rate ˃ 20% of
baseline value), hypotension (decrease in systolic blood
pressure ˃ 20% baseline value)
- Postoperative nausea and vomiting, urinary retention
(inability to pass urine even once during the first 24 hours),
lower limb weakness
- Injury to the underlying structures (injury to the liver or a
viscus), or hematoma formation as recorded under
ultrasound guidance
- Need of postoperative mechanical ventilation or ICU
admission
- LA toxicity. |
intraoperative and postoperative |
Secondary Outcome |
Hemodynamic parameters (heart rate, systolic and mean arterial
blood pressure) |
5 min after intubation, 5 min after block injection, 15 min after skin incision, 30 min after skin incision, 60 min after skin incision, 90 min after skin incision, 5 min after extubation |
