Comment on: “Impact of opioid-free anaesthesia on postoperative nausea, vomiting and pain after gynaecological laparoscopy - A randomised controlled trial”

[...]the selection of study drugs and the post-operative pain management methods chosen here might have contributed to the difference in the PONV as well as pain scores and the cumulative morphine consumption compared to previously published studies on OFA. Ultimately, the similar dose of postoperative morphine consumption seen here may have accounted for the similar PONV patterns. [...]we believe that OFA based on drugs with brief effects, and without utilization of all recommended modalities, might not offer a fair evaluation of the technique.
