BACKGROUND: Anaesthesiologists are facing the problem of an increasing population of morbidly obese patients. In order to minimize the risk of opioid-induced postoperative respiratory failure, the intraoperative administration of opioids should be reduced or replaced with other drugs. The purpose of this study was to compare haemodynamic response elicited by intubation in morbidly obese patients between two variants of anaesthesia induction: fentanyl-based or low-opioid using dexmedetomidine...

Obesity is an increasing problem worldwide. The number of people with obesity doubled since the 1980's to affect an estimated 671 million people worldwide. Obese patients in general have an altered respiratory physiology and can have an impaired lung function, which leads to an increased risk of developing pulmonary complications during anaesthesia and after bariatric surgery (approximately 8%). Therefore the respiratory management of the bariatric surgical patient provides a number of challenges. This review will focus on the perioperative respiratory care in bariatric surgical patients discussing respiratory physiology in the obese and perioperative respiratory care in bariatric surgery...

INTRODUCTION: Type 2 diabetes (T2D) in association with obesity is an increasing disease burden. Bariatric surgery is the only effective therapy for achieving remission of T2D among those with morbid obesity. It is unclear which of the two most commonly performed types of bariatric surgery, laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB), is most effective for obese patients with T2D. The primary objective of this study is to determine whether LSG or LRYGB is more effective in achieving HbA1c<6% (<42 mmol/mol) without the use of diabetes medication at 5 years...

Bariatric surgery is a rapidly growing and dynamic discipline necessitating a specialised anaesthetic approach coordinating high-risk patients with appropriate post-operative intensive care (ICU) support. The relationship between the anaesthetic and ICU utilisation after bariatric surgery is poorly understood. All adult bariatric surgery patients admitted to any ICU over a five-year period between 2007 and 2011 in Western Australia were identified from hospital admission records and cross-referenced against the Western Australian Department of Health Data Linkage Unit database...

PURPOSE OF REVIEW: The purpose of this review is to describe an evidence-based drug strategy applicable to any obese patient, rather than to present one standard 'ideal' anaesthetic drug combination. The ultimate choice of specific drugs in any given situation will depend upon clinician experience, patient specifics, and drug availability. The fundamental principle in anaesthesia for the obese patient is to use the shortest acting, least fat soluble agents to ensure rapid recovery to safe levels of alertness and mobility...

The use of angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARB) for the treatment of hypertensive obese patients is steadily increasing. Some studies have reported that the use of these drugs was associated with an increased risk of hypotensive episodes, during general anaesthesia. The number of bariatric procedures is also increasing worldwide, but there is a lack of studies investigating the hypotensive effect of renin-angiotensin system (RAS) blockers in severely obese patients during general anaesthesia for bariatric surgery...

Bariatric surgery has been proved to be the safest and efficient procedure in treating morbid obese patients, but data is still lacking in the elderly population. The aim of our study was to compare the safety and efficacy of laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG) in patients aged more than 55 years. We performed a retrospective review of a prospectively collected database. All patients with body mass index (BMI) ≧32 kg/m(2) and aged more than 55 years undergoing LRYGB or LSG in BMI Surgery Centre, E-Da Hospital between January 2008 and December 2011 with at least one year of follow up were included for the analysis...

BACKGROUND: The use of videolaryngoscopes is recommended as a part of routine practice in anaesthesia for morbidly obese patients. The aim of this study was to evaluate C-Mac in a group of morbidly obese patients to see if it improves intubation conditions. METHODS: 86 morbidly obese (BMI > 40 kg m⁻²) patients scheduled for bariatric surgery were included in the study. In every studied case, C-Mac was used with a Mackintosh shaped blade. For the first attempt, the anaesthetists performing the intubation were asked to use a videolaryngoscope as a standard laryngoscope (they were blinded to the monitor display) and evaluate the glottic view in direct laryngoscopy...

BACKGROUND: As a result of the increasing prevalence of obesity in the UK, anesthetists are increasingly encountering overweight and obese patients in routine practice. There is currently a paucity of evidence to guide best clinical practice for anesthetists managing overweight and obese patients. The current guidelines from the Association of Anaesthetists of Great Britain and Ireland (AAGBI), entitled Peri-Operative Management of the Morbidly Obese Patient, give an excellent overview of organizational issues, but leave much clinical detail to the discretion of the individual clinician...
