Background. Retrospective study in patients undergoing cataract surgery by facoemulsification in order to evaluate the incidence of regional peribulbar anaesthesia compared with MAC (Monitored Anesthesia Care).
Methods. Between January 1999 and December 2000, 1902 patients were studied. Peribulbar anaesthesia was performed by using a double or single infero-lateral injection with a mixture of Lidocaine 2% and Bupivacaine 0.5% or, as a single agent, of Ropivacaine 0.75%. Jaluronydase 10 UI/ml was added to either agents.
Results. Only in 8% of patients intravenous drugs were added during surgery to correct bradycardia in 3%, hypertension in 3% and for sedation in 2%.
Conclusions. Regional anesthesia represents the most suitable anesthesia technique in patients undergoing cataract surgery by facoemulsification. Only in 8% of patients MAC was suitable, due to excessive anxiety or cardiovascular imbalance. Compared to other anesthesia techniques, regional anaesthesia is significantly safer. The utility of preoperative tests in reducing the morbidity associated with surgery, is also discussed.
