Filter by:This study compares a volume targeted pressure support non-invasive ventilation with an automatic PEP regulation (AVAPS-AE mode) to a pressure support non-invasive ventilation (S/T mode) in patients with acute hypercapnic respiratory failure with acidosis. This study focuses on patients at risk of obstructive apneas or obesity-hypoventilation syndrom (BMI≥30 kg/m²). Half of participants (33 patients) will receive non invasive ventilation with AVAPS-AE mode, the other half will receive non-invasive ventilation with S/T mode.
The aim of this study is to validate the downloadable mobile snore applications by polysomnography.
Adenotomy, together with tonsillectomy, belongs among the most frequently performed surgical procedures in paediatric patients. These surgical procedures are associated with the second highest incidence of post-operative nausea and vomiting (PONV) (following strabism correction surgery) in paediatric surgery. PONV is associated, apart from the discomfort for the child, with a number of complications: dehydration, metabolic disruption or danger of haemorrhage and aspiration of the gastric content. Adenotomy is a typologically completely different surgical procedure, with a different target structure of the surgery, and the length and invasiveness of the procedure. Thus, it is possible to expect a difference in PONV incidence when compared to tonsillectomy. Adenotomy is a surgical procedure performed namely in children of the pre-school age. This is associated, among others, also with the problem of objectivization of post-operative nausea, which is very difficult to verbalize in small children, being a subjective feeling of body discomfort. It is possible to expect that the overall incidence of PONV will be significantly underestimated.
Oral appliances (OA) have emerged as an alternative to continuous positive airway pressure (CPAP) for obstructive sleep apnea (OSA) treatment. The most commonly used OA reduces upper airway collapse by advancing the mandible (mandibular advancement devices, MAD). There is a strong evidence base demonstrating that MADs improve OSA in the majority of patients, including some with more severe disease. However, MADs are not efficacious for all, with approximately one-third of patients experiencing no therapeutic benefit. Patients often prefer MADs to gold-standard CPAP treatment. Head-to-head trials confirm CPAP is superior in reducing OSA parameters on polysomnography; however, this greater efficacy does not necessarily translate into better health outcomes in clinical practice. Comparable effectiveness of MADs and CPAP has been attributed to higher reported nightly use of MADs, suggesting that inferiority in reducing apnoeic events may be counteracted by greater treatment adherence. The MAD in study, called Bite-Velo Linguale (BVL), features a novel monobloc device including a tongue retainer, a suction cavity that maintains the tongue down onto the mouth floor in order to prevent it from raising towards the hard palate, and therefore increasing the retro lingual aerial space. Its design requires the presence of only four occlusal points, allowing for a direct anchorage onto the mandibular bone, thus reducing the risk for occlusal changes, tooth loosening and the development of an anterior cross bite, which represent some of the major long-term adverse effects of oral appliances. MADs are generally well tolerated, although short-term adverse effects during acclimatization are common. Long-term dental changes do occur, but these are for the most part subclinical and do not preclude continued use. The BVL in study features technological advances aimed at preventing long-term dental changes, as well as improving tolerability and easiness of use.
The purpose of this study is to compare the effect of mandibular advancement bite block and high flow nasal cannula to standard bite block for oxygenation, capnographic measurement, prevention of hypoxemia, intervention events and adverse effects during endoscopic examinations.
