Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Pain and physical function are similar following axillary, muscle-sparing vs posterolateral thoracotomy.
We set out to determine whether there is a difference in postoperative pain and recovery after the patient undergoes the axillary muscle-sparing incision (ie, muscle-sparing thoracotomy [MT]) vs the modified posterolateral incision (ie, posterolateral thoracotomy [PT]). ⋯ When comparing patients who had undergone vertical, axillary, wholly MT to those who had undergone modified serratus muscle-sparing PT, postoperative differences in pain were not apparent. One should not anticipate reduced pain or more rapid overall recovery following MT, at least when epidural analgesia is used aggressively for perioperative pain control.

Randomized Controlled Trial Comparative Study Clinical Trial
Dornase alfa reduces air trapping in children with mild cystic fibrosis lung disease: a quantitative analysis.
To evaluate quantitative air trapping measurements in children with mild cystic fibrosis (CF) lung disease during a 1-year, double-blind, placebo-controlled, recombinant human deoxyribonuclease (rhDNase) [dornase alfa] intervention trial and compare results from quantitative air trapping with those from spirometry or visually scored high-resolution CT (HRCT) scans of the chest. ⋯ Quantitative air trapping is a more consistent sensitive outcome measure than either spirometry or total HRCT scores, and can discriminate differences in treatment effects in children with minimal CF lung disease.

Effects of aerosolized adenosine 5'-triphosphate vs adenosine 5'-monophosphate on dyspnea and airway caliber in healthy nonsmokers and patients with asthma.
Extracellular adenosine 5'-triphosphate (ATP) causes neurogenic bronchoconstriction, inflammation, and coughs, and may play a mechanistic role in obstructive airway diseases. The aims of this study were to determine the effects of inhaled ATP on airway function, and to compare these effects with those of adenosine 5'-monophosphate (AMP). ⋯ ATP is a more potent bronchoconstrictor and has greater effects on dyspnea and other symptoms than AMP in asthmatic patients. Therefore, ATP could potentially be used as a bronchoprovocator in the clinical setting.

Dexamethasone: benefit and prejudice for patients undergoing on-pump coronary artery bypass grafting: a study on myocardial, pulmonary, renal, intestinal, and hepatic injury.
Cardiac surgery with cardiopulmonary bypass (CPB) results in perioperative organ damage caused by the systemic inflammatory response syndrome (SIRS) and ischemia/reperfusion injury. Administration of corticosteroids before CPB has been demonstrated to inhibit the activation of the systemic inflammatory response. However, the clinical benefits of corticosteroid therapy are controversial. This study was designed to document the effects of dexamethasone on cytokine release and perioperative myocardial, pulmonary, renal, intestinal, and hepatic damage, as assessed by specific and sensitive biomarkers. ⋯ Even while inhibiting SIRS, dexamethasone treatment offered no protection against transient, subclinical, perioperative abdominal organ damage. Tryptase release could have a preconditioning effect, offering protection against perioperative intestinal and renal damage. Dexamethasone treatment resulted in more pronounced postoperative pulmonary dysfunction, prolonged time to tracheal extubation, and initiated postoperative hyperglycemia in patients undergoing elective on-pump coronary artery bypass graft surgery.

Manual hyperinflation improves alveolar recruitment in difficult-to-wean patients.
To investigate the effect of manual hyperinflation (MH) in patients with atelectasis associated with ventilation support. ⋯ MH performed on patients with atelectasis from ventilation support significantly improved alveolar recruitment.
