简要总结
This study aims to compare visual analogue scale with pupillary diameter for assessment of postoperative pain in patients undergoing lower abdominal surgeries under spinal anaesthesia It is a prospective observational study conducted on 90 patients Pain scores using visual analogue scale and pupillary diameter using handheld infrared pupillometer will be recorded at 4 6 8 12 and 24 hours after surgery along with haemodynamic parameters The correlation between pupillary diameter and visual analogue scale will be evaluated to determine if pupillometry can serve as an objective tool for pain assessment
