title: Effect of tracheal intubation or laryngeal mask airway insertion on intraocular pressure using balanced anesthesia with sevoflurane and remifentanil.
abstract: OBJECTIVE
  To study the effect of tracheal intubation or laryngeal mask airway (LMA) insertion on intraocular pressure (IOP) in strabismus patients undergoing balanced anesthesia with sevoflurane and remifentanil.
  
  
  METHODS
  Open, prospective, randomized study.
  
  
  METHODS
  Tertiary care academic medical institution.
  
  
  METHODS
  40 adult ASA physical status I and II patients scheduled for elective strabismus surgery.
  
  
  METHODS
  Patients were randomized to receive either tracheal intubation or LMA insertion following mask induction with sevoflurane in combination with IV remifentanil.
  
  
  METHODS
  Intraocular pressure, mean arterial pressure (MAP), and heart rate (HR) were measured before induction, immediately following induction, and after airway insertion.
  
  
  RESULTS
  Intraocular pressure after tracheal intubation or LMA insertion did not differ significantly from preoperative baseline values. Mean arterial pressure and HR did not significantly differ between groups at any time point.
  
  
  CONCLUSIONS
  Remifentanil and sevoflurane are not associated with an increase in IOP response during tracheal intubation or LMA insertion above baseline in healthy patients undergoing ophthalmic surgery.
