BACKGROUND/AIMS: It is unclear whether patients with irritable bowel syndrome (IBS) require a high dose of sedatives during colonoscopy. In this study, we investigated the pre-procedural anxiety levels, sedative consumption, procedure times, complications, and patient's satisfaction between patients with IBS and controls for ambulatory colonoscopy under sedation. MATERIALS AND METHODS: Rome III criteria were used in the diagnosis of IBS. Anxiety levels were measured using Spielberger's State-Trait Anxiety Inventory (STAI) and Beck Anxiety Inventory (BAI)...

REVIEW
Jonas Andersson Lindholm
Veno-venous extracorporeal membrane oxygenation (VV ECMO) is used for support in patients with severe respiratory failure. The method allows extracorporeal gas exchange and may replace the patient's lung function for weeks and even years. ECMO is not a contraindication for lung transplant. The most important factor for a good outcome is the physiological status of the patient when accepted for transplantation. Ambulatory ECMO makes it possible for the patient to exercise and walk, and provides the best outcome for high risk patients in severe respiratory failure...

BACKGROUND: May patients with interstitial lung disease (ILD) require supplementary oxygen (O2 ) therapy to maintain normoxia. However, ambulatory O2 delivery devices are constraining and cumbersome. The physiologic and symptomatic impact of these devices on ILD patients is unknown. METHODS: We conducted a prospective study of 30 clinically stable ILD patients (with varying disease severity), half of whom used O2 at baseline. Each subject completed two six-minute walk tests (6MWTs); for O2 users, one walk was completed while wearing a backpack (weight 7...

BACKGROUND: The supraglottic airway (SGA) represents an alternative to endotracheal intubation (endotracheal tube [ETT]) in many types of ambulatory surgery. Adoption of the SGA has progressed slowly in sinonasal surgery due to concerns about airway protection. The purpose of this study was to compare quality of life measures and indices of airway protection between patients undergoing sinonasal surgery who were ventilated via an SGA or ETT. METHODS: Patients undergoing outpatient sinonasal surgery were enrolled into a randomized, single-blind study in which patients would be ventilated with either an SGA or ETT...

We investigated the relationship between ambulatory blood pressure (BP) and oxygen desaturation index (ODI), while accounting for pulse rate and age. ODI was assessed by overnight finger pulse oximetry in 2342 participants on the day of ambulatory BP monitoring, and calculated as the number of desaturation episodes per sleeping hour. Both BP and pulse rate increased significantly (P ≤ .006) from normal (< 5 events/h) to mildly (5-14), moderately (15-30), and severely (≥ 30 events/h) elevated ODI...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO), when used as bridge to lung transplantation (BTT) identifies high-risk candidates. Recent advances in cannula design and patient selection fosters "awake ambulatory ECMO" as a viable option for critically ill candidates in an attempt to retard deconditioning while awaiting allografts. METHODS: From 2012 to 2015, 30 patients underwent ECMO as BTT. Candidacy for ECMO was determined prior to listing for transplant...

Two landmark trials conducted more than 35 years ago provided scientific evidence that, under very specific circumstances, long-term oxygen therapy (LTOT) may prolong life. These two trials enrolled 290 patients with chronic obstructive pulmonary disease and severe daytime hypoxemia documented by direct arterial blood gas measurement. From that time, LTOT became a standard of care, and the indications for oxygen therapy expanded to include nocturnal oxygen therapy for isolated nocturnal oxygen desaturation, ambulatory oxygen to correct exercise-induced desaturation, and short-burst oxygen to relieve dyspnea...

Oxidative stress has been implicated in the development of hypertension, arterial stiffness and atherosclerosis. Optimal functioning of the enzymatic antioxidant system is central to prevent increased oxidative stress and its consequences. We aimed to investigate the relationships of ambulatory blood pressure and carotid intima-media thickness with enzyme activities of the glutathione cycle in 396 young, black and white South Africans of the African-PREDICT study. Ambulatory blood pressure and carotid intima-media thickness were measured and glutathione peroxidase and glutathione reductase activities were analyzed...

BACKGROUND: Ambulatory oxygen (O2 ) is the recommended treatment for hypoxemia at rest or induced by exercise. Commercial aircraft often fly at altitudes of 30,000 feet; their cabins are pressurized to altitudes of 6,000-8,000 feet, with an equivalent FIO2 of 0.15. O2 supplementation, for those receiving baseline ambulatory O2 , is paramount. METHODS: We gathered information on subjects' experience traveling with supplementary oxygen and reasons individuals receiving O2 do not travel...

Adenosine plays a role in the energy supply of cells and provokes differential, hormone-like functions in circulating cells and various tissues. Its release is importantly regulated by oxygen tension. This renders adenosine and its kinetics interesting to investigate in humans subjected to low oxygen conditions. Especially for space exploration scenarios, hypoxic conditions - together with reduced gravity - represent two foreseen living conditions when planning manned long-duration space missions or planetary habitats...
