I'm an anesthesiologist but I've been in pain practice for many years. Spent years in academics doing anesthesia and pain but now just pain for long enough that a lot of things like eyes I have little recollection of. I have a famil member (mom) age 89, morbid obesity and moderate to severe copd with bronchiectasis. On supplemental oxygen at 2-3 liters/min, bronchodilators and inhaled steroids. Vision deteriorating due to cataracts. I have putting it off and putting it off but now she can barely read and that is one of her few remaing pleasures. My question is to those of you who regularly do eyes. I understand that this is a "peripheral" surgery that can be done with topical anesthesia or regional. However, from a practical standpoint can this be done in someone with these comorbities that prevent someone from lying flat and may experiencing coughing during the procedure? I recall eye patients having multiple medical problems but I don't recall these severe pulmonary issues and do recall coughing is a no-no. Appreciate any input
