Summary

The oculocardiac reflex (OCR), a trigeminal-vagal response, occurred in 25% of blepharoplasty patients during eye manipulation. Awareness is crucial for managing this potentially life-threatening reflex.

Area of Science:

  • Ophthalmology
  • Cardiology
  • Anesthesiology

Background:

  • The oculocardiac reflex (OCR) is a trigeminal-vagal-mediated reflex arc.
  • This reflex, characterized by bradycardia or dysrhythmia during ocular manipulation, has not been previously described in aesthetic blepharoplasty.

Purpose of the Study:

  • To describe the occurrence and characteristics of the oculocardiac reflex during aesthetic blepharoplasty.
  • To identify patient and surgical factors associated with the oculocardiac reflex.

Main Methods:

  • A prospective study involving 100 patients undergoing aesthetic blepharoplasty.
  • Intraoperative monitoring of heart rate and rhythm.
  • Data collection using a standardized operating room data sheet to identify reflex-prone patients (RPPs).

Main Results:

  • The oculocardiac reflex occurred in 25% of patients (25 out of 100).
  • Reflex-prone patients were identified as young, anxious females with a cardiac history, undergoing light anesthesia with aggressive fat pad resection.
  • OCR was more frequent during medial fat pad traction and in the left eye.

Conclusions:

  • The oculocardiac reflex is a significant phenomenon in aesthetic blepharoplasty.
  • Identifying reflex-prone patients and understanding triggers are essential for prevention and management.
  • Close patient surveillance and prompt intervention are mandatory to manage this potentially life-threatening reflex.
