No full textObstructive sleep apnoea syndrome (OSAS) is a rather common sleep disorder and
constitutes a risk or an aggravating factor for various underlying diseases. OSAS is
characterised by repeated upper airway collapse during sleep causing fragmented
sleep, hypoxemia and hypercapnia. It may also cause considerable changes in intrathoracic
pressure and an increase in sympathetic nervous activity, which represent
the basis of associated pathologies such as arterial hypertension, ischaemic heart
disease, diabetes mellitus, stroke and sudden death [1]. Moreover, there is a wellestablished
association between OSAS and postoperative complications [2, 3].
Nevertheless, a significant proportion of patients affected by OSAS undergo surgery
without diagnosis and, consequently, without therapy [4]. Therefore, it is crucial for
the anaesthesiologist to identify patients at risk of OSAS before surgery for a correct
definition of a perioperative strategy to reduce the risk of perioperative complication.
This process should be done independently and regardless of whether the
patient undergoes general or locoregional anaesthesia
Physiopathological rationale of using high-flow nasal therapy in the acute and chronic setting: A narrative review
Full text linkChronic lung disease and admissions due to acute respiratory failure (ARF) are becoming increasingly common. Consequently, there is a growing focus on optimizing respiratory support, particularly non-invasive respiratory support, to manage these conditions. High flow nasal therapy (HFNT) is a noninvasive technique where humidified and heated gas is delivered through the nose to the airways via small dedicated nasal prongs at flows that are higher than the rates usually applied during conventional oxygen therapy. HFNT enables to deliver different inspired oxygen fractions ranging from 0.21 to 1. Despite having only recently become available, the use of HFNT in the adult population is quite widespread in several clinical settings. The respiratory effects of HNFT in patients with respiratory failure may be particularly relevant for clinicians. In this narrative review, we discuss the main pathophysiological mechanism and rationale for using HFNT in the acute and chronic setting
