Randomized Controlled Trial Comparative Study
Analgesia and pulmonary function after lung surgery: is a single intercostal nerve block plus patient-controlled intravenous morphine as effective as patient-controlled epidural anaesthesia? A randomized non-inferiority clinical trial.
Thoracic epidural anaesthesia (EDA) is regarded as the 'gold standard' for postoperative pain control and restoration of pulmonary function after lung surgery. Easier, less time-consuming, and, perhaps, safer is intercostal nerve block performed under direct vision by the surgeon before closure of the thoracotomy combined with postoperative i.v. patient-controlled analgesia with morphine. We hypothesized that this technique is as effective as thoracic EDA. ⋯ In patients undergoing lung surgery, single intercostal nerve block plus i.v. patient-controlled analgesia with morphine is not as effective as patient-controlled EDA with respect to pain control and restoration of pulmonary function.

Randomized Controlled Trial
Dexmedetomidine inhibits gastric emptying and oro-caecal transit in healthy volunteers.
Dexmedetomidine is a potent and selective α2-adrenoceptor agonist used for perioperative and intensive care sedation with certain beneficial qualities. However, based on preclinical observations, it might inhibit gastric emptying and gastrointestinal transit, which could result in unwanted effects in intensive care patients. This study evaluated the effects of dexmedetomidine on gastric emptying and oro-caecal transit time in healthy volunteers. ⋯ Dexmedetomidine markedly inhibits gastric emptying and gastrointestinal transit in healthy volunteers.
