Randomized Controlled Trial
The effects of doxapram on time to tracheal extubation and early recovery in young morbidly obese patients scheduled for bariatric surgery: A randomised controlled trial.
Bariatric surgery is a well established treatment of the obese. Postoperative respiratory failure and airway obstruction after bariatric surgery can often be attributed to the residual depressant effects of anaesthetics, sedatives and opioids. Peri-operative management of morbidly obese patients is still a concern for operating room professionals. ⋯ Iranian Registry of Clinical Trials (IRCT) http://www.irct.ir/ number IRCT2017060712203N9.

Observational Study
Pre-anaesthesia ultrasonography of the subclavian/infraclavicular axillary vein for predicting hypotension after inducing general anaesthesia: A prospective observational study.
Bedside sonography of the inferior vena cava has been demonstrated to be a reliable tool for assessing intravascular volume status. Subclavian vein (SCV) assessment was proposed as a reasonable adjunct for measuring the inferior vena cava. ⋯ The collapsibility index of the SCV-AV during deep inspiration was a significant predictor of IOH occurrence and the percentage decrease in MAP after inducing anaesthesia. Further studies in patients with higher collapsibility index are needed to confirm our findings, before the collapsibility index of the SCV-AV can be recommended unequivocally for clinical use.

Randomized Controlled Trial
Internal carotid artery blood flow is enhanced by elevating blood pressure during combined propofol-remifentanil and thoracic epidural anaesthesia: A randomised cross-over trial.
Anaesthesia reduces mean arterial pressure (MAP), and to preserve organ perfusion, vasopressors are often used to maintain MAP above 60 mmHg. Cognitive dysfunction is common following major surgery and may relate to intra-operative cerebral hypoperfusion. ⋯ During combined propofol-remifentanil and thoracic epidural anaesthesia, ICA flow increased by approximately 15% when the MAP was elevated from about 60 to 80 mmHg. Treatment of a reduction in MAP brought about by anaesthesia seems to enhance ICA flow.

Randomized Controlled Trial
Comparison of conventional and fibreoptic-guided advance of left-sided double-lumen tube during endobronchial intubation: A randomised controlled trial.
Postoperative sore throat and airway injuries are relatively common after double-lumen tube (DLT) intubation. ⋯ The fibreoptic-guided advancement seems to reduce irritation to the airway, leading less postoperative complications.
