METHOD FOR RETROBULBAR ANAESTHESIA IN VITREORETINAL SURGERIES

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine, namely anaesthiology in ophthalmosurgery, and may be used in vitreoretinal surgeries, including those terminated by the stage of introducing silicone oil. For this purpose, 40-45 minutes before the operation, the retrobulbar introduction of a mixture of 2% lidocaine and 0.75% ropivacaine in proportions 1:1 in the amount of 4-5 ml is prescribed. It is followed by the intraoperative intravenous titration introduction of 0.01% nitroglycerine starting with 1 ml 1-2 minute before the introduction of silicone oil in response to a surgeon's signal. The nitroglycerine introduction is terminated when patient's systolic blood pressure becomes lower than the initial values by 10-20%.;EFFECT: method provides adequate anaesthesia combined with a reduced risk of developing complications due to blood pressure correction at the specific stage of surgery.;1 ex
