Postoperative Pulmonary Complications
Br J Anaesth. 2017;118(3):317-334.
Changes to the respiratory system occur immediately on induction of general anaesthesia: respiratory drive and muscle function are altered, lung volumes reduced, and atelectasis develops in > 75% of patients receiving a neuromuscular blocking drug..The respiratory system may take 6 weeks to return to its preoperative state after general anaesthesia for major surgery.
clinicians should be aware of non-modifiable and modifiable factors in order to recognize those at risk and optimize their care.Preventative measures include preoperative optimization of co-morbidities, smoking cessation, and correction of anaemia, in addition to intraoperative protective ventilation strategies and appropriate management of neuromuscular blocking drugs. Protective ventilation includes low tidal volumes, which must be calculated according to the patient's ideal body weight.
the most beneficial level of PEEP is required,
