Summary

Patient-controlled sedation with midazolam or propofol effectively reduced anxiety during cataract surgery. Both agents helped control heart rate, with midazolam also managing arterial pressure increases.

Area of Science:

  • Anesthesiology
  • Ophthalmology
  • Pharmacology

Background:

  • Cataract surgery often requires sedation to manage patient anxiety and improve surgical conditions.
  • Peribulbar block is a common anesthesia technique for cataract surgery.
  • Patient-controlled sedation (PCS) offers a potential method for tailored anxiety management.

Purpose of the Study:

  • To evaluate the efficacy of patient-controlled midazolam versus propofol for sedation during cataract surgery under peribulbar block.
  • To compare the anxiolytic effects and hemodynamic stability provided by self-administered midazolam and propofol.

Main Methods:

  • Randomized controlled trial involving patients undergoing cataract surgery with peribulbar block.
  • Three groups: patient-controlled midazolam, patient-controlled propofol, and a saline control group (for blinding).

  • Median doses administered: midazolam 2.54 mg, propofol 87.4 mg.

    • Main Results:

    • Patient-controlled sedation significantly reduced anxiety scores in both midazolam and propofol groups compared to saline (P < 0.05).
    • Midazolam and propofol prevented increases in heart rate during surgery.
    • Midazolam uniquely prevented increases in arterial pressure, unlike propofol and saline.

    Conclusions:

    • Patient-controlled administration of midazolam or propofol is effective in reducing anxiety during cataract surgery.
    • Midazolam offers an advantage by also controlling arterial pressure increases, in addition to heart rate.
    • Further research may explore optimal dosing and patient selection for PCS in ophthalmic procedures.
