Sevoflurane and propofol anesthesia both effectively reduce intraocular pressure (IOP) during surgery. This study found no significant difference in IOP control between sevoflurane and propofol maintenance anesthesia.

Area of Science:

  • Anesthesiology
  • Ophthalmology

Background:

  • Intraocular pressure (IOP) control is crucial during anesthesia and surgery.
  • Previous studies have explored various anesthetic agents for IOP management.

Purpose of the Study:

  • To compare the effects of sevoflurane versus propofol anesthesia on intraocular pressure during maintenance and recovery.
  • To evaluate IOP control in patients undergoing elective non-ophthalmic surgery.

Main Methods:

  • A randomized study involving 33 patients (ASA I-II) undergoing elective non-ophthalmic surgery.
  • Anesthesia maintained with either sevoflurane (1.5-2.5 vol%) or propofol (4-8 mg kg(-1) h(-1)).
  • Intraocular pressure measured using Perkins applanation tonometry by a blinded ophthalmologist.

Main Results:

Related Experiment Videos

  • Both sevoflurane and propofol anesthesia led to a significant decrease in intraocular pressure post-induction and during maintenance.
  • No statistically significant differences in intraocular pressure were observed between the sevoflurane and propofol groups.

Conclusions:

  • Sevoflurane provides comparable intraocular pressure reduction to propofol during anesthesia maintenance.
  • Both anesthetic agents are effective in maintaining a reduced intraocular pressure level.
