Summary
Dixyrazine and diazepam were compared as premedicants for geriatric cataract surgery. Dixyrazine showed less anxiolytic effect and required more sedation than diazepam.
Area of Science:
- Anesthesiology
- Geriatric Medicine
- Pharmacology
Background:
- Premedication is crucial for managing patient anxiety and sedation before surgery.
- Geriatric patients undergoing cataract surgery require careful consideration of premedicant choice due to potential comorbidities and altered drug metabolism.
Purpose of the Study:
- To compare the efficacy of peroral dixyrazine versus diazepam as premedicants in geriatric patients undergoing cataract surgery.
Main Methods:
- A randomized study involving 100 geriatric patients (50 per group) undergoing cataract surgery.
- Patients received either peroral dixyrazine (15-30 mg) or diazepam (4-10 mg) as premedication.
- Anxiety levels and need for supplemental intravenous sedatives were assessed throughout the study period.
Main Results:
- A significantly higher incidence of anxiety was observed in the dixyrazine group compared to the diazepam group.
- Dixyrazine patients required more frequent supplementation with intravenous sedatives.
- The difference in anxiety levels between the two groups was statistically significant.
Conclusions:
- Peroral dixyrazine is less effective than diazepam in reducing anxiety for geriatric patients undergoing cataract surgery.
- Dixyrazine may be suitable for calm patients requiring minimal sedation or avoidance of somnolence.
- Diazepam appears to be a more effective premedicant for managing anxiety in this patient population.
