Early intervention for perioperative hypertension in cataract surgery

Area of Science:

• Ophthalmology
• Cardiology
• Anesthesiology

Background:

• Perioperative blood pressure control is crucial, particularly for high-risk individuals undergoing surgery.
• Limited research exists on early monitoring of blood pressure fluctuations before cataract surgery.
• Hypertension management during ophthalmic procedures requires careful consideration.

Purpose of the Study:

• To evaluate the efficacy of early intervention for perioperative hypertension in patients undergoing cataract surgery with topical anesthesia.
• To compare a standardized blood pressure monitoring and control protocol against conventional methods.

Main Methods:

• A retrospective observational study comparing 134 patients (standardized group) with early monitoring to 134 controls (conventional management).
• Phacoemulsification and intraocular-lens insertion were performed in all participants.
• Perioperative blood pressure, pulse pressure, and heart rate were recorded at multiple time points.

Main Results:

• The standardized group showed significantly lower systolic pressure changes upon entering the operating room, and at the beginning and end of surgery.
• No significant differences in blood pressure control were observed between etizolam and nicardipine use.
• The early monitoring protocol effectively managed perioperative hypertension.

Conclusions:

• Early monitoring and control of blood pressure are effective in managing perioperative hypertension during cataract surgery.
• This standardized approach can be implemented without requiring additional pharmacologic agents.
• The findings suggest broad applicability in clinical settings for ophthalmic surgery.
