Much cosmetic surgery is typically performed under full general anaesthesia but it may, in skilled hands, be performed under sedation and local anaesthesia.
There are various factors that indicate suitability for this but if appropriate for you, these techniques can result in much lower quantities of anaesthetic drugs being used with consequent benefits in rapid recovery and less nausea. This has particular benefits in those prone to sickness after anaesthesia and in those who particularly wish to avoid general anaesthesia for whatever reason.
You can find out more in my Frequently Asked Questions. I will be happy to discuss this with you in detail in the setting of your cosmetic surgery consultation.
