Randomized Controlled Trial Comparative Study
Dexmedetomidine vs remifentanil intravenous anaesthesia and spontaneous ventilation for airway foreign body removal in children.
To compare the safety and efficacy of dexmedetomidine/propofol (DP)-total i.v. anaesthesia (TIVA) vs remifentanil/propofol (RP)-TIVA, both with spontaneous breathing, during airway foreign body (FB) removal in children. ⋯ Compared with RP-TIVA, DP-TIVA provided more stable respiratory and haemodynamic profiles, but required a longer recovery time. Clinical trial registration China Clinical Research Information Service, ChiCTR-TRC-13003018.

Randomized Controlled Trial Comparative Study
Comparison of gas exchange after lung resection with a Boussignac CPAP or Venturi mask.
Postoperative continuous positive airway pressure (CPAP) can improve lung function. The aim of our study was to assess the efficacy of prophylactic CPAP on the Pa(O2)/FI(O2) ratio measured the day after surgery in patients undergoing lung resection surgery (LRS). ⋯ In patients undergoing LRS, prophylactic CPAP during the first 6 h after surgery with a pressure of 5-7 cm H2O improved the Pa(O2)/FI(O2) ratio at 24 h. This effect was more evident in patients with increased risk of postoperative pulmonary complications.

Randomized Controlled Trial
Reduced local immune response with continuous positive airway pressure during one-lung ventilation for oesophagectomy.
Transthoracic oesophagectomy requires prolonged one-lung ventilation causing systemic and local inflammatory responses. Application of continuous positive airway pressure (CPAP) to the collapsed lung potentially reduces pulmonary damage, hypoxia, and consequent inflammation. This randomized controlled trial studied the influence of CPAP applied to the collapsed right lung during thoracoscopic oesophagectomy on local and systemic inflammatory response. ⋯ A significantly lower local immune response was observed during one-lung ventilation when CPAP was applied to the collapsed lung. The findings suggest a beneficial effect of CPAP on the collapsed lung during oesophagectomy with one-lung ventilation.

Neurogenic stress cardiomyopathy (NSC) is a well-known syndrome complicating the early phase after an acute brain injury, potentially affecting outcomes. This article is a review of recent data on the putative role of localization and lateralization of brain lesions in NSC, cardiac innervation abnormalities, and new polymorphisms and other genetic causes of the sympathetic nervous system over-activity. Concerns regarding the management of stress-related cardiomyopathy syndromes during the perioperative period are also discussed. Future clinical research should explore whether specific factors explain different patient susceptibilities to the disease and should be directed towards early identification and stratification of patients at risk, so that such patients can be more carefully monitored and appropriately managed in critical care and during the perioperative period.

Randomized Controlled Trial
Opioid-free total intravenous anaesthesia reduces postoperative nausea and vomiting in bariatric surgery beyond triple prophylaxis.
Patients undergoing bariatric surgery are at high risk of postoperative nausea and vomiting (PONV). Despite triple PONV prophylaxis, up to 42.7% of patients require antiemetic rescue medication (AERM). ⋯ This prospective randomized study demonstrates that opioid-free TIVA is associated with a large reduction in relative risk of PONV compared with balanced anaesthesia. Clinical trial registration NCT 01449708 (ClinicalTrials.gov).
