2.4. Outcome Measures
nerve block-related, pain, cough, vascular injury, muscle pain, hypotension
SECONDARY, COMPLICATIONS
The primary outcomes were the visual analogue scale (VAS) scores at rest and cough during 48 h postoperatively and the postoperative consumption of pain rescue. The secondary outcomes include the QoR15 score at 24 h and 48 h postoperatively, data related to the usage of opioids during and after an operation, and nerve block-related complications, such as hypotension, vascular injury, and muscle pain at the injection site. Intraoperative hypotension was defined as a decrease in mean arterial pressure greater than 20% of the baseline. Additionally, the dermatomal distribution of the sensory blockade (area between anterior axillary and middle axillary) was collected.
