Greetings. Welcome to HCM and thank you for your question. I understand your concern. Well, our main concern, as doctors, as the side effects of general anaesthesia. It is commonly known that a large amount of risk in perioperative period can come from side effects of anaesthesia. My opinion is that this is the case. You see, during general anaesthesia all the organism is controlled basically by machines and vital parameters are controlled externally. It is more than understandable that there will be a slight disturbance in organism equilibrium after weaning off from anaesthesia, such as blurry vision or speech, high heart rate or low saturation, due to intubation applied during anaesthesia. I am glad that surgical removal of the lesion went fine. The other effects may be easily attributed to general anaesthesia, and normal gain of function is just a matter of little time. My opinion is that there is nothing to worry about and these symptoms will abolish in no time. I hope I was helpful with my answer. Take care. Best regards, Dr. Meriton
