Accumulation of carbon dioxide under ophthalmic drapes during eye surgery: a comparison of three different drapes

Abstract: Carbon dioxide accumulation under ophthalmic drapes is caused by their impaired permeability to exhaled carbon dioxide in spontaneously breathing patients. Three different ophthalmic drapes were examined under clinical conditions. Sixty unpremedicated patients of each gender, aged over 60 years and with an ASA status of I–III undergoing cataract surgery under retrobulbar anaesthesia were included in the study. Patients with known pulmonary diseases were excluded. The patients were divided into three groups of … Show more

“…It has been reported that during the investigative period, no significant differences were measured in MAP or HR in patients undergoing cataract surgery with local anesthesia. 1,3,21,22 Similarly, we did not observe any changes in SBP, DBP, MAP, or HR in our fentanyl group. Cardiovascular parameters were more stable in the fentanyl group than they were in the control group.…”

“…5 Expired CO 2 accumulates under the surgical drapes and patients breathe in the air containing the higher CO 2 concentration, resulting in an increased arterial CO 2 concentration. 3,5,19,21 To reduce the arterial CO 2 concentration, patients increase their RR. [3][4][5]21 We observed a statistically significant increase in RR in the control group but did not observe any significant change in the fentanyl group.…”
