Filter by:The aim of our study is to show that continuous oxygen reserve index monitoring is a non-invasive monitoring method that can be used as a supporting parameter to PaO2 in blood gas in hypoxia and hyperoxia monitoring when different fresh gas flow is used in general anesthesia.
The induction of general anaesthesia is associated with a fall in lung volume due in particular to a decrease in muscle tone and the formation of denitrogenation atelectasis. Many recent studies insist on the need to apply a so-called "protective" strategy of intraoperative ventilation, which combines the use of recruitment manoeuvres, reduced tidal volume (Vt) (6-8ml/kg) and positive expiratory pressure (PEEP) to prevent these phenomena. However, the setting of PEEP remains debated and several authors agree on the need to individualize ventilatory parameters, particularly in obese patients, without describing the individualization tools. In the ICU, it has been shown that electrical impedance tomography (EIT) can be used to individualise the PEEP level in a simple and non-invasive way. Therefore, we wish to determine whether the use of this technique during general anaesthesia allows for the individualization of PEEP, and whether the value determined is correlated with the body mass index (BMI).
This study is designed as an open label, single dose combination of HSK3486 and etomidate in healthy adult male subjects. The study will evaluate the anesthetic/sedation effect of the combination of the 2 drugs and the safety profile including pain on injection, hypotension, tachycardia or bradycardia effects (HSK3486), and involuntary muscle movements, nausea and vomiting potential and adrenal suppression (etomidate). All subjects will be administered HSK3486 plus etomidate. Subjects will be confined to the study unit from the evening of Day -1 until the morning of Day 2, then will be required to return for a follow up visit on Day 7. Intensive PD, PK, safety and tolerability and assessments will be performed prior to dosing on Day 1 until 24 hours post-dose (Day 2).
