(Please list the details of your past surgical procedures, in particular if you have undergone a lap band (laparoscopic gastric banding) procedure. If you have ever had any anaesthetic problems or anaesthetic complications (eg. severe nausea/vomiting, perioperative cardiac events etc) please ensure you mention them here including the name of the hospital(s). Providing these details can help in retrieving previous anaesthetic records meaning past problems could potentially be avoided)
