The use of highKeywords: Intrathecal,diamorphine,neuroaxial,bariatric,bariatric surgery Abstract: The use of intrathecal diamorphine is not commonplace in laparoscopic bariatric surgery. At our institution, a major UK bariatric centre, high-dose intrathecal diamorphine is routinely utilised. Data were analysed retrospectively. Fifty-three patients who had a spinal anaesthetic were matched against age, sex, body mass index and surgical procedure type to generate controls. Pain scores were recorded in the post-anaesthetic care unit on arrival, after 1?hour and on discharge to the ward. Post-operative nausea and vomiting; post-operative hypertension; pruritus; 24-hour morphine consumption and length of stay were measured. Pain scores were better in the spinal anaesthetic group in all measured categories (p?=?0.033, p?<?0.01, p?<?0.01); post-operative nausea and vomiting was less common in the spinal anaesthetic group (p?<?0.01); post-operative hypertension was less common in the spinal anaesthetic group (p?=?0.25); pruritus was more common in the spinal anaesthetic group (p?<?0.01); morphine consumption was less common in the spinal anaesthetic group (p?=?0.037). Length of hospital stay was reduced by 12.4?hours (p?=?0.025). We propose that this is a practical and safe technique to adopt. A randomised-control trial will need to be conducted in order to find the most efficacious volume of local anaesthetic and dose of diamorphin
