BackgroundIntubation and extubation of ventilated patients are not risk-free procedures in the intensive care unit (ICU) and can be associated with morbidity and mortality. Intubation in the ICU is frequently required in emergency situations for patients with an unstable cardiovascular or respiratory system. Under these circumstances, it is a high-risk procedure with life-threatening complications (20–50%). Moreover, technical problems can also give rise to complications and several new techniques, such as videolaryngoscopy, have been developed recently. Another risk period is extubation, which fails in approximately 10% of cases and is associated with a poor prognosis. A better understanding of the cause of failure is essential to improve success procedure.Results and conclusionIn constructing these guidelines, the SFAR/SRLF experts have made use of new data on intubation and extubation in the ICU from the last decade to update existing procedures, incorporate more recent advances and propose algorithms.

A best evidence topic was constructed according to a structured protocol. The question addressed was whether the use of transcutaneous electrical nerve stimulation (TENS) is effective in reducing post-thoracotomy pain. Of the 74 papers found with a report search, nine prospective randomized controlled trials (RCT), among which three were double-blind, presented the best evidence to answer the clinical question. All investigated the effect of TENS as an adjunct therapy for relieving acute post-thoracotomy pain in patients undergoing thoracic surgery. The authors, journal, date and country of publication, study type, group studied, relevant outcomes and results of these papers are given. We conclude that a vast majority - seven of the nine retrieved studies - were in favor of TENS as an adjuvant to narcotic analgesics for improving outcome after thoracic surgery. Indeed, the interest and benefit has been shown not only in the treatment of acute post-thoracotomy pain (pain scores and narcotic requirements were consistently lower in the TENS group as opposed to the Placebo-TENS group), but also when used together with narcotic analgesics to reduce the duration of recovery room stay and to increase chest physical tolerance (better coughing attempts during chest physiotherapy) with positive effects on pulmonary ventilator function [forced expiratory volume in 1 s (FEV(1)) and/or forced vital capacity (FVC)]. Specifically, the TENS treatment was shown to be ineffective when used alone in severe post-thoracotomy pain (i.e. posterolateral thoracotomy incision), but useful as an adjunct to other medications in moderate post-thoracotomy pain (i.e. muscle sparing thoracotomy incision) and very effective as the sole pain-control treatment in patients experiencing mild post-thoracotomy pain (i.e. video-assisted thoracoscopy incision). Hence, current evidence shows TENS associated with postoperative medications to be safe and effective in alleviating postoperative pain and in improving patient recovery, thus enhancing the choice of available medical care and bettering outcome after thoracic surgery.

A best evidence topic was constructed according to a structured protocol. The question addressed was whether the use of non-invasive ventilation (NIV) associated with chest physiotherapy (CPT) is effective in preventing respiratory complications in patients undergoing lung resection surgery. Of the 172 papers found using a report search, five presented the best evidence to answer the clinical question. The authors, journal, date and country of publication, study type, group studied, relevant outcomes and results of these papers are given. We conclude that, on the whole, the five studies were all in favor of NIV as an adjuvant to CPT for improving outcome after lung resection surgery. Indeed, the interest and benefit has been shown not only in the treatment of postoperative acute respiratory failure, but also in the prevention and treatment of respiratory complications (atelectasis, pneumonia and bronchial congestion). Hence, current evidence shows NIV associated with acute CPT management to be safe and effective in reducing postoperative complications and in improving patient recovery, thus enhancing the choice of available medical care and bettering outcome in lung resection surgery.
