Abstract    Major surgical procedures usually cause or exacerbate respiratory insufficiency, and postoperative pain is one of the common reasons. However, clinicians seldom or never use any analgesics for such patients, when considering the respiratory side effects of the analgesics, as results in a vicious circle of “baseline respiratory insufficiency-surgical attack and postoperative pain-deteriorated respiratory insufficiency”. It is important to choose an appropriate postoperative analgesic pattern in patients with baseline respiratory insufficiency to promote their function recovery and to reduce postoperative complications.
