Purpose

To evaluate systolic and diastolic blood pressure during phacotrabeculectomy performed under regional anaesthesia with retrobulbar block and intravenous analgosedation with midazolam and fentanyl.

Material and methods

68 patients were involved into the study: I Group: 37 patients with chronic cardiovascular and metabolic diseases: 22 women and 15 men (45 operations), mean aged 72,02 years, mean weight 73,4 kg, II Group: 31 patients without additional diseases: 20 women and 11 men (44 operations), mean aged 70 years, mean weight 68,9 kg. Systolic and diastolic arterial blood pressure was recorded at 5-minutes intervals throughout the intraoperative period and anesthetist intervened medically when necessary.

Results

In I Group statistically significant mean systolic BP decrease was observed in 5 and 20 minute after injection of midazolam and fentanyl and mean diastolic BP decrease was observed in 5 and 15 minute after analgosedation. In II Group statistically significant mean systolic BP decrease was noted in 5 minute and mean diastolic BP decrease in 5 and 35 minute. During phacotrabeculectomy mean systolic and diastolic BP was statistically higher in I group. In I group 12 patients and in II group 4 patients required additional antihypertensive drug.

Conclusions

Regional anaesthesia with retrobulbar block and intravenous analgosedation provides hemodynamic stability.
