193-Child Tonsil-Surgery Comparison Linked Anesthetic Choice to Recovery Measures Without Random Assignment
A comparative pediatric series reported faster recovery with remimazolam. Its group allocation and limited follow-up leave uncertainty about the independent drug effect and broader psychological claims.

What the groups represented
Wan and colleagues examined 193 tonsillectomy and adenoidectomy patients: eighty-three received propofol and 110 received remimazolam. The study compared perioperative vital signs, spontaneous breathing, eye opening, extubation, postoperative ratings, and hospital stay.
The remimazolam group had more favorable values on several recovery measures. Surgical duration was not significantly different, showing that the observed pattern was not uniform across all recorded times.
Why selection matters
A nonrandom comparative design can reflect clinician choice, patient characteristics, timing, and other care differences. Similar measured demographics cannot exclude all those explanations. Recovery ratings also do not directly establish lasting psychological well-being, despite the broad wording of the title.
The single-center setting and limited postoperative assessment restrict generalization. Different sedation and pain scales measure different aspects of recovery and should not be collapsed into one cognitive endpoint.
Use in testimony
Separate a shorter extubation time from reliable recall, emotional recovery, or long-term safety. The study can describe an association in the observed surgical population, but cannot show that changing anesthetic alone would have changed another child’s outcome.
