BACKGROUND: Non-anesthesia administered propofol (NAAP) has been shown to be a safe and effective method of sedation for patients undergoing gastrointestinal endoscopy. Bariatric surgery patients are potentially at a higher risk for sedation-related complications due to co-morbidities including obstructive sleep apnea. The outcomes of NAAP in bariatric patients have not been previously reported. METHODS: In this retrospective cohort study, severely obese patients undergoing pre-surgical outpatient esophagogastroduodenoscopy (EGD) were compared to non-obese control patients (BMI ≤ 25 kg/m(2)) undergoing diagnostic EGD at our institution from March 2011-September 2015 using our endoscopy database...

BACKGROUND: Bronchoscopy is a safe and minimally invasive diagnostic tool, but no studies have reported prospectively on sedation and outcomes in patients with objectively defined obesity. OBJECTIVES: The purpose of the study is to determine if obese patients require more sedation or had more procedural complications during bronchoscopy under moderate sedation than non-obese patients. METHODS: We evaluated complications and sedation requirements in non-obese versus obese patients, defined by multiple criteria including body mass index (BMI), neck circumference, abdominal height, and Mallampati scores...

This article reviews the data for diagnostic and uncomplicated therapeutic upper endoscopy, which show it is safe and effective to perform the procedure under moderate sedation with a combination of benzodiazepine and opioids. For more complex procedures or for superobese patients anesthesia support is recommended. Performing endoscopy in this population should alert providers to plan carefully and individualize sedation plans because there is no objective way to quantify this risk pre-endoscopically.

BACKGROUND AND OBJECTIVES: Current treatments for overweight adults include reduced-calorie diet, exercise, behavior modification, and selective use of medications. Many achieve suboptimal results with these measures and progress to obesity. Whether the intragastric balloon (IGB), a reversible device approved for treatment of obesity, is a safe and effective option in overweight adults is less well studied. We conducted a study to prospectively analyze the safety and effectiveness of IGB in overweight adults, to compare the results to a simultaneously studied cohort of obese patients, and to share procedural tips for safe IGB placement and removal...

INTRODUCTION: Obstructive sleep apnoea (OSA), the most common type of sleep-disordered breathing, is associated with significant immediate and long-term morbidity, including fragmented sleep and impaired daytime functioning, as well as more severe consequences, such as hypertension, impaired cognitive function and reduced quality of life. Perioperatively, OSA occurs frequently as a consequence of pre-existing vulnerability, surgery and drug effects. The impact of OSA on postoperative respiratory complications (PRCs) needs to be better characterised...

BACKGROUND: The prevalence of obesity in developed countries is rising. Currently, Europe has a prevalence of 9-30% with significant impact on public health systems. Obese patients in ICUs require special management and treatment. Altered anatomy in obese patients complicates procedures such as mechanical ventilation. Obesity affects cardiopulmonary physiology and requires elevated ventilation pressures. In our retrospective study, we determined the effect of early percutaneous dilatational tracheotomy (PDT) and cessation of sedation on respiratory parameters in severely obese subjects...

BACKGROUND AND STUDY AIMS: Colonoscopy with inhaled methoxyflurane (Penthrox) is well tolerated in unselected subjects and is not associated with respiratory depression. The aim of this prospective study was to compare the feasibility, safety, and post-procedural outcomes of portable methoxyflurane used as an analgesic agent during colonoscopy with those of anesthesia-assisted deep sedation (AADS) in subjects with morbid obesity and/or obstructive sleep apnea (OSA). PATIENTS AND METHODS: The outcomes of 140 patients with morbid obesity/OSA who underwent colonoscopy with either Penthrox inhalation (n = 85; 46 men, 39 women; mean age 57...

BACKGROUND AND AIMS: A purely endoluminal method of GI bypass would be desirable for the treatment of obstruction, obesity, or metabolic syndrome. We have developed a technology based on miniature self-assembling magnets that create large-caliber anastomoses (Incisionless Anastomosis System [IAS]). The aim of this study was to evaluate procedural characteristics of IAS deployment and long-term anastomotic integrity and patency. METHODS: We performed a 3-month survival study of Yorkshire pigs (5 interventions, 3 controls)...

A 41-year-old woman with concomitant severe obesity, obstructive sleep apnea syndrome, and asthma was scheduled for endoscopic cholecystectomy. She was 165.8 cm tall and weighed 141.2 kg, with BMI of 51.4. We were concerned with difficulty in ventilation and intubation at the time of anesthesia induction and intra- and post-operative ventilatory failure. After sedation with fentanyl and droperidol together with intraoral local anesthesia with lidocaine (Xylocaine Viscous), the intubating laryngeal mask (ILMA) was inserted while awake, and after the confirmation of adequate ventilation, the bronchoscope was inserted into the guide...

OBJECTIVES: Procedural sedation/anesthesia outside the operating room for a variety of procedures is well described with an overall low adverse event rate in certain settings. Adverse event associated with procedural sedation/anesthesia outside the operating room for gastrointestinal procedures have been described, albeit in small, single-center studies with wide variance in outcomes. Predictors of such outcomes are unclear. We aimed to estimate the prevalence of adverse event in children undergoing procedural sedation/anesthesia outside the operating room for esophagogastroduodenoscopy, colonoscopy, or both to identify predictors of adverse event...

BACKGROUND: Opioids are commonly used after bariatric surgery for pain control because of their potent analgesic effects. Nevertheless, the morbidly obese patient has increased risk for developing adverse effects produced by opioids (such as sedation, apnea, hypoxemia, ileus, and vomiting). Intravenous acetaminophen (IVA) has been evaluated in some specialties showing a reduction in opioid consumption. The purpose of this study was to evaluate the effect on opioid consumption when IVA is administered in bariatric surgery patients...

We present a 17-year-old man who underwent brain magnetic resonance imaging and laboratory exams for uncontrolled seizure. Patients with an autistic disorder require deep sedation or, occasionally, general anesthesia even for radiologic exams or simple procedures. The anesthetic management of an obese, violent patient with a severe autistic disorder and mental retardation can be challenging to anesthesiologists and requires a more careful approach in selecting adequate anesthetics and doses. This case emphasizes the importance of having a detailed plan to ensure the smooth process of premedication, anesthetic induction, maintenance, emergence and safe discharge of incorporated patients in the event of unexpected situations...

Endoscopic submucosal dissection (ESD) has been proposed as the gold standard in the treatment of early gastric cancer because it facilitates a more accurate histological assessment and reduces the risk of tumor recurrence. However, the time course of ESD for large gastric tumors is frequently prolonged because of the tumor size and technical difficulties and typically requires higher doses of sedative and pain-controlling drugs. Sedative or anesthetic drugs such as midazolam or propofol are used during the procedure...
