Prospective data collection does not remove treatment-selection bias.
The single-center study assigned 135 endoscopy patients nonrandomly to midazolam–dezocine sedation, anesthetic endoscopy or ordinary endoscopy. Sedation patients reported less pain and greater satisfaction than the ordinary group. The anesthesia group had more recorded complications than the other groups.
The groups were unblinded and nonrandomized. Patient selection and procedure characteristics can affect comfort and adverse events. Midazolam was paired with an analgesic, so pain differences cannot be assigned to the benzodiazepine alone. Similar outcome averages do not establish treatment equivalence.
For an expert opinion, identify the actual comparator and the meaning of each complication. Distinguish patient-reported comfort, depth of anesthesia and respiratory monitoring. The report supports a setting-specific association, not proof that the combination supplies the same benefits and risks as general anesthesia.
