BACKGROUND: Atherosclerotic conditions have been demonstrated to be associated with sleep- disordered breathing (SDB). Peripheral arterial disease (PAD) represents severe atherosclerosis with a high mortality. In early stages of PAD a substantial prevalence of sleep apnoea has already been shown. Here, we sought to determine the frequency of undiagnosed sleep apnoea in a homogeneous group of advanced PAD patients undergoing percutaneous revascularization. METHODS: 59 consecutive patients (mean age: 71...

BACKGROUND: Hypoxemia increases the risk of intubation markedly. Such concerns are multiplied in the emergency department (ED) and during retrieval where patients may be unstable, preparation or preoxygenation time limited and the environment uncontrolled. Apneic oxygenation is a promising means of preventing hypoxemia in this setting. AIM: To test the hypothesis that apnoeic oxygenation reduces the incidence of hypoxemia during endotracheal intubation in the ED and during retrieval...

BACKGROUND AND AIMS: Neonates and infants are prone to oxygen desaturation during the induction of general anaesthesia. Pharyngeal oxygen insufflation has been shown to delay the onset of desaturation and hypoxaemia during apnoea. We tested the hypothesis that deep laryngeal oxygenation with Oxiport(®) Miller blade would delay the onset of desaturation compared to laryngoscopy without supplemental oxygen (Miller blade). METHODS: One hundred neonates and infants undergoing general anaesthesia with endotracheal intubation for surgery were recruited and randomly assigned to one of the two groups: Miller or Oxiport group (laryngoscopy performed with Miller or Oxiport(®) blade, respectively)...

BACKGROUND: Vitamin D (Vit D) insufficiency has been implicated in the pathophysiology of numerous diseases. Obstructive sleep apnoea syndrome (OSAS), a disorder associated with increased cardiovascular and cerebrovascular morbidity, has been associated with lowered Vit D levels, but reports are inconclusive. AIM: To evaluate the association between serum 25-hydroxyvitamin D [25(OH)D], a marker of Vit D status, and anthropometric and sleep characteristics of OSAS patients and to compare those levels between OSAS patients and non-apnoeic controls...

Background.: Apnoeic oxygenation during anaesthesia has traditionally been limited by the rapid increase in carbon dioxide and subsequent decrease in pH. Using a Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) technique a slower increase in carbon dioxide than earlier studies was seen. Notably, apnoeic oxygenation using THRIVE has not been systematically evaluated with arterial blood gases or in patients undergoing laryngeal surgery. The primary aim of this study was to characterize changes in arterial P O 2 , P CO 2 and pH during apnoeic oxygenation using THRIVE under general anaesthesia...

Obstructive sleep apnoea syndrome (OSAS) is characterized by recurrent partial or complete pharyngeal collapses during sleep. The pathophysiology of OSAS is complex and multifactorial. Factors influencing upper airway patency include a reduction in upper airway dimensions that can result from both anatomical and functional alterations (obesity, fluid shift or maxillo-facial structural changes), and increased pharyngeal collapsibility owing to reduced neuromuscular compensation and lack of the pharyngeal protective reflex during sleep...

BACKGROUND: Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) was introduced to adult anaesthesia to improve the safety of airway management during apnoea before intubation. The objective of our study was to determine whether THRIVE safely prolongs apnoeic oxygenation in children. METHODS: This was a randomized controlled trial in 48 healthy children, with normal airways and cardiorespiratory function, in age groups 0-6 and 7-24 months, 2-5 and 6-10 yr old, presenting for elective surgery or imaging under general anaesthesia...

Apnoeic oxygenation during intubation is used to prevent desaturation during intubation. The aim of this review was to assess whether apnoeic oxygenation during endotracheal intubation reduced the incidence of hypoxaemia. Five major databases were systematically searched for all relevant studies published up to May 2016. All study designs with a control group and a group receiving apnoeic oxygenation were included in this review. These studies were then assessed for level of evidence and risk of bias. The data were then analysed using a meta-analysis...

The various physiological changes in pregnancy make the parturient vulnerable for early and rapid desaturation. Severe hypoxaemia during intubation can potentially compromise two lives (mother and foetus). Thus tracheal intubation in the pregnant patient poses unique challenges, and necessitates meticulous planning, ready availability of equipment and expertise to ensure maternal and foetal safety. The All India Difficult Airway Association (AIDAA) proposes a stepwise plan for the safe management of the airway in obstetric patients...

PURPOSE: High-flow nasal cannula oxygen (HFNC) has the potential to provide apnoeic oxygenation. We decided to assess in a proof-of-concept study whether the addition of HFNC to non-invasive ventilation (NIV) could reduce oxygen desaturation during intubation, compared with NIV alone for preoxygenation, in severely hypoxaemic intensive care unit (ICU) patients with respiratory failure. METHODS: We conducted a randomised, controlled, single-centre trial with assessor-blinded outcome assessment in patients admitted to the ICU...

Affecting a large number of middle-aged, frequently overweight subjects, obstructive sleep apnea (OSA) is the most common sleep related breathing disorder. Partial or complete upper airway (UA) collapse during sleep causing repeated apneic episodes, which is the leading pathophysiological mechanism underlying the disorder, results in arterial oxygen desaturation and recurrent arousals from sleep to re-establish airway patency. Untreated OSA is commonly associated with a range of adverse consequences, including cardiovascular complications, such as arterial and/or pulmonary hypertension, arrhythmias, stroke, as well as diabetes mellitus and metabolic syndrome, and motor vehicle accidents...

INTRODUCTION: Tracheal intubation in the intensive care unit (ICU) is associated with severe life-threatening complications including severe hypoxaemia. Preoxygenation before intubation has been recommended in order to decrease such complications. Non-invasive ventilation (NIV)-assisted preoxygenation allows increased oxygen saturation during the intubation procedure, by applying a positive end-expiratory pressure (PEEP) to prevent alveolar derecruitment. However, the NIV mask has to be taken off after preoxygenation to allow the passage of the tube through the mouth...

Recent studies have shown that nasal oxygen delivery can prolong the time to desaturation during apnoea in the non-pregnant population. We investigated the benefits of apnoeic oxygenation during rapid sequence induction in the obstetric population using computational modelling. We used the Nottingham Physiology Simulator, and pre-oxygenated seven models of pregnancy for 3 min using Fi O2 1.0, before inducing apnoea. We found that increasing Fi O2 at the open glottis increased the time to desaturation, extending the time taken for Sa O2 to reach 40% from 4...

A shortcut review of the literature was carried out to establish whether the use of apnoeic oxygenation technique during endotracheal intubation reduces the incidence of critical desaturation. Four trials were found to be directly relevant to the three-part question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line is that there is emerging evidence that the use of apnoeic oxygenation decreases the incidence of critical desaturation during endotracheal intubation...

BACKGROUND: The optimal method for out-of-hospital ventilation during cardiopulmonary rescue (CPR) is controversial. The aim of this study was to test different modes of ventilation during CPR for a prolonged period of 60 min. METHODS: Pigs were randomized to four groups after the induction of ventricular fibrillation, which was followed by one hour of mechanical cardiac compressions. The study comprised five pigs treated with free airways, five pigs treated with ventilators, six pigs treated with a constant oxygen flow into the tube, and six pigs treated with apnoeic oxygenation...

BACKGROUND: The 'classical' technique of rapid sequence induction (RSI) of anaesthesia was described in 1970. With the introduction of new drugs and equipment in recent years, a wide variation in this technique has been used. The role of cricoid pressure is controversial because of the lack of scientific evidence. Moreover, gentle mask ventilation has been recommended in situations such as obesity and critically ill patients, to prevent hypoxaemia during the apnoeic period. In identifying multiple techniques, we conducted a national postal survey to establish the current practice of RSI in the UK...

PURPOSE: Inflammation and oxidative stress play important roles in the pathogenesis of obstructive sleep apnoea syndrome (OSAS). Omentin is expressed in visceral adipose tissue and is associated with the inflammatory response. The aim of this study was to assess the relationship between OSAS and omentin based on a comparison of its serum levels at baseline and after 3 months of continuous positive airway pressure (CPAP) therapy. METHODS: Ninety-six newly diagnosed OSAS patients and 31 non-apnoeic controls were enrolled in this study...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is a technique widely used worldwide to improve gas exchange. Changes in ECMO settings affect both oxygen and carbon dioxide. The impact on oxygenation can be followed closely by continuous pulse oximeter. Conversely, carbon dioxide equilibrates much slower and is not usually monitored directly. METHODS: We investigated the time to stabilization of arterial carbon dioxide partial pressure (PaCO2) following step changes in ECMO settings in 5 apnoeic porcine models under veno-venous ECMO support with polymethylpentene membranes...
