2023年1月29日 · Upper airway obstruction during general anesthesia usually necessitates the insertion of a laryngeal mask airway or endotracheal tube to preserve airway patency. Likewise, the patient's spontaneous ventilation is often inadequate, requiring partial or complete mechanical support with positive pressure ventilation.

Spontaneous ventilation during general anaesthesia has been shown to favour atelectasis formation and decreased functional residual capacity. Therefore, general anaesthesia is commonly associated with endotracheal intubation and mechanical ventilation.

Usually, general anaesthesia is associated with controlled ventilation and endotracheal intubation, but, when a neuromuscular blockade is not necessary for the type of surgery, the patients can be maintained in spontaneous breathing or in different assisted ventilation modes …

2019年8月10日 · Physiology, advantages, disadvantages and potential role of spontaneous breathing during surgery as compared to intermittent positive pressure ventilation will be described in this article.

It has been stated that spontaneous breathing during general anesthesia is associated with hypercapnic acidosis and an increased work of breathing in both healthy patients and those with known comorbidities. In order to smooth this process, assisted ventilation modes have been introduced in anesthesia machines.

In acute hypoxemic respiratory failure (AHRF) and acute respiratory distress syndrome (ARDS) patients, spontaneous breathing is associated with multiple physiologic benefits: it prevents muscles atrophy, avoids paralysis, decreases sedation needs and is …

2024年7月5日 · Patient self-inflicted lung injury (P-SILI) is a controversial, emerging concept, whereby intense inspiratory efforts by spontaneously breathing patients – whether assisted or unassisted – may exacerbate lung injury.

Methods: The use of spontaneous ventilation general anesthesia without intubation is proposed for all operations not requiring muscular paralysis and where the patient's conditions are compatible. The authors describe the technique used and its utilisation in over 4,000 patients undergoing orthopedic surgery of the leg.

2020年2月13日 · Spontaneous ventilation VATS (SV-VATS) techniques have unique advantages that can avoid the shortcomings of intubated anesthesia: (I) spontaneous ventilation can be maintained; (II) only simple intravenous drug use, local infiltration anesthesia, intercostal nerve block, or epidural block is needed for anesthesia and analgesia; (III) the use of ...

2010年6月1日 · Spontaneous ventilation during general anaesthesia has been shown to favour atelectasis formation and decreased functional residual capacity. Therefore, general anaesthesia is commonly associated with endotracheal intubation and mechanical ventilation.
