New concepts of atelectasis during general anaesthesia.
At the beginning of the last century, Pasteur described postoperative pulmonary atelectasis, analysed postoperative pulmonary complications (PCC; see below) and noted: `when the true history of postoperative lung complications comes to be written, active collapse of the lung, from de®ciency of inspiratory power, will be found to occupy an important position among determining causes'. Indeed, at...
متن کاملDynamics of re-expansion of atelectasis during general anaesthesia.
A major cause of impaired gas exchange during general anaesthesia is atelectasis, causing pulmonary shunt. A 'vital capacity' (VC) manoeuvre (i.e. inflation of the lungs up to 40 cm H2O, maintained for 15 s) may re-expand atelectasis and improve oxygenation. However, such a manoeuvre may cause adverse cardiovascular effects. Reducing the time of maximal inflation may improve the margin of safet...
متن کاملA ventilation strategy during general anaesthesia to reduce postoperative atelectasis
BACKGROUND Atelectasis is common during and after general anaesthesia. We hypothesized that a ventilation strategy, without recruitment manoeuvres, using a combination of continuous positive airway pressure (CPAP) or positive end-expiratory pressure (PEEP) and a reduced end-expiratory oxygen fraction (FETO2) before ending mask ventilation with CPAP after extubation would reduce the area of post...
متن کاملInfluence of age on atelectasis formation and gas exchange impairment during general anaesthesia.
We have studied the effects of anaesthesia on atelectasis formation and gas exchange in 45 patients of both sexes, smokers and nonsmokers, aged 23-69 yr. None of the patients showed clinical signs of pulmonary disease, and preoperative spirometry was normal. In the awake patient, partial pressure of arterial oxygen (PaO2) decreased with increasing age (P less than 0.001) and the alveolar-arteri...
متن کاملMinimizing atelectasis formation during general anaesthesia—oxygen washout is a non-essential supplement to PEEP
BACKGROUND Following preoxygenation and induction of anaesthesia, most patients develop atelectasis. We hypothesized that an immediate restoration to a low oxygen level in the alveoli would prevent atelectasis formation and improve oxygenation during the ensuing anaesthesia. METHODS We randomly assigned 24 patients to either a control group (n = 12) or an intervention group (n = 12) receiving...
