Nasal High Flow in Bariatric Surgery

Morbid Obesity

High frequency nasal cannula (HFNC) provides an inspiration O2 fraction of 21-1% and it has a minimal dead space and can be well tolerated due to humidified air. Group I patients will be applied HFNC before and after bariatric surgery, Group II patients will be applied a constant O2 concentration via face mask. Oxygen pressure, oxygen saturation, carbon dioxide, respiration frequency, forced vital capacity will be measured before and after surgery.

Investigation of Microbiome-based Prognostical Biomarkers in Patients With Morbid Obesity and Bariatric...

ObesityMorbid3 more

Morbid obesity leads to non-alcoholic fatty liver disease (NAFLD), and not all NAFLD cases benefit from weight loss e.g. after bariatric surgery. Our aim is to find out, which intrahepatic factors and / or biomarkers might be beneficial or can be identified as prognostic factors for remission of NAFLD after weight loss. As other factors such as the microbiome or muscle and fatty tissue also influence the development of obesity and liver diseases, it is planned to examine these parameters before and after bariatric surgery as well. Tissue biopsies will therefore be taken during the surgery, and blood as well as stool samples will be collected and compared for suitable biomarkers before and after the intervention.

Laryngeal Mask in Morbid Obesity

Morbid Obesity

Investigators study the performance of both masks, Proseal Laryngeal Mask Airway (PLMA) and I-gel, as temporary ventilatory supraglottic airway devices (SGDs) before tracheal intubation in morbidly obese patients. Data are lacking in such population of patients

Evaluation of Preoperative Nasoendoscopy to Predict Difficult Intubation

Difficult or Failed IntubationObesity1 more

Despite the availability of different methods for airway assessment, unexpectedly difficult intubations occur at a frequency of up to 15%. A variety of pre-intubation clinical screening tests have been advocated to predict difficult laryngoscopy and airway but their usefulness is limited in obese patients. Could awake invasive airway assessment be more predictive for difficult airways in obese patients? The use of nasendoscopy assessment for the airway could be a useful additional invasive tool to predict the difficult airway in obese

Incidence of Complications Associated With Anesthesia in Obesity Parturient Undergoing Cesarean...

Cesarean Section ComplicationsAnesthesia Complication2 more

The incidence of obesity parturient has been increasing worldwide. There was a report revealing one third of pregnant women in United state considered obesity. Obesity is associated with increased in maternal and neonatal complications. Also, there was an increasing in the rate of cesarean delivery. Anesthetic management of the obese parturient is differ from non-obese parturients. There were higher risk of difficult intubation, failed intubation, pulmonary aspiration and difficult regional anesthesia such as spinal anesthesia or epidural catheter placement comparing with non-obese parturient. The aim of the study is to report complication associated with anesthesia in obese patients undergoing cesarean delivery in Single University hospital, Bangkok, THAILAND.

Impact of Social Distancing on Bariatric Versus Non-Surgical Obese Patients During COVID-19 Pandemic...

Diabetes MellitusType 23 more

In response to the COVID-19 pandemic, weight management programs and metabolic surgery have been deferred to contain the virus. Quarantine and social distancing negatively impact dietary, exercise and psychological health of obese individuals. The study aims to evaluate the impact of social distancing measures on post-metabolic surgery patients compare to non-surgical obese patients and discuss potential strategies for management post COVID-19.

Physiological Effects of Gastric Sleeve Operation

ObesityMorbid1 more

After gastric sleeve patients undergo a substantial weight loss, but the physiological mechanisms behind the weight loss is not fully elucidated. Studies suggest that gut-hormone secretion is altered comparable to what is also seen after Roux-en-Y gastric bypass, however to which extent is not fully established and furthermore, the mechanisms behind an altered secretion are unclear. The purpose of this study is to investigate absorption and postprandial metabolism of glucose and protein in addition to gut hormonal responses after gastric sleeve compared with a group of un-operated subjects machted on sex, age and BMI. Furter, a group of Roux-en-Y gastric bypass operated patients matched on pre-operative BMI, current BMI, sex and age will be included for comparison.

Changes in Ingestive Behaviour Following Gastric Bypass

Morbid Obesity

The gastric bypass procedure is known to be one of the most successful treatments for morbid obesity and Type 2 diabetes mellitus, and has been shown to decrease appetite, energy intake, body weight and glycemia both in the short and long term. A number of reports hypothesise that these changes may be driven, at least in part, by positive shifts in food preferences following surgery. However, findings are drawn from self-reported dietary intakes which are beset with measurement bias, thus precluding definite conclusions. The current work aims to directly observe food intake to test the hypothesis that after gastric bypass food intake changes in a manner which leads to beneficial outcomes on body weight when compared to weight stable control participants. Patients (n=32) with a planned gastric bypass procedure will be recruited from Phoenix Health (Ireland and England) and Letterkenny University Hospital (Ireland), alongside control participants (n=32) with no planned weight loss. All subjects will attend the Human Intervention Studies Unit (HISU), Ulster University on five occasions (1-month pre-surgery and 3, 12, 24 and 60 months post-surgery, with controls being time-matched). Study visits will be fully residential involving two overnight stays within the facility during which participants' 24-hour food intake will be covertly measured (7am-11pm Day 2 and breakfast Day 3) and the following procedures undertaken; basal metabolic rate, body composition, bone health, assessment of liking/wanting high fat foods and post-meal gut hormone responses. On each study visit participants will have ad lib access to a range of foods of varying macronutrient composition and which are compatible with their stated food preferences (assessed prior to the start of the study). Changes in all ingestive behaviours will be evaluated over time as compared to the control participants.
