The prevalence of obesity is on the upward trend world-wide. In the United States of America, the incidence of obesity has doubled over the past 20 years. The extent of obesity is usually quantified through the body mass index (BMI), which is defined as the relationship between height and weight. The use of regional anaesthetic techniques for obese patients is increasing in popularity as this offers distinct advantages over general anaesthesia for these patients. Anesthetists must completely assess the patients before the surgery to identify anesthesia- related potential risk factors and prepare for management. Key words: Anaesthetic, Bariatric, Surgery
