Randomized Controlled Trial Comparative StudyRole of sevoflurane in organ protection during cardiac surgery in children: a randomized controlled trial.
The protective effects of volatile anaesthetics against ischaemia-reperfusion injury have been shown in vitro, but clinical studies have yielded variable results. We hypothesized that, in children, sevoflurane provides superior cardioprotection after cardiac surgery on cardiopulmonary bypass (CPB) compared with totally intravenous anaesthesia (TIVA). ⋯ Sevoflurane did not provide superior myocardial protection in our general paediatric cardiac surgical population. In children under 6 months, however, sevoflurane might be beneficial in comparison with midazolam. The conditioning effects of sevoflurane in specific paediatric subgroups need to be further investigated.

Randomized Controlled Trial Comparative StudyA home-made animal model in comparison with a standard manikin for teaching percutaneous dilatational tracheostomy.
As airway management specialists, thoracic surgeons should be familiar with percutaneous dilatational tracheostomy. To optimize the learning curve, we propose a home-made pig model obtained from a slaughterhouse for training residents in the technical aspects of performing percutaneous dilatational tracheostomy. The satisfaction of the residents' training experience using this model was compared with that using a standard manikin model. ⋯ Our pig model allowed residents to develop the skills required for successful percutaneous dilatational tracheostomy. In particular, they developed confidence with certain manoeuvres such as needle and guide-wire placement, dilatation of the trachea and insertion of a cannula, before attempting the procedure on a live patient.

Multicenter Study Observational StudyRed blood cell transfusion is a determinant of neurological complications after cardiac surgery.
The aim of this study was to evaluate the impact of red blood cell (RBC) transfusions on the occurrence of stroke and transient ischaemic attack (TIA) after cardiac surgery. ⋯ Transfusion of more than 2 units of RBCs after cardiac surgery is associated with a significantly increased risk of postoperative stroke and TIA.

Randomized Controlled TrialThe dose-related effects of dexmedetomidine on renal functions and serum neutrophil gelatinase-associated lipocalin values after coronary artery bypass grafting: a randomized, triple-blind, placebo-controlled study.
Acute kidney failure after coronary artery bypass grafting (CABG) is a serious complication that increases morbidity and mortality rates. Early detection and prevention of this complication are very important. A novel biomarker named neutrophil gelatinase-associated lipocalin (NGAL) can play an important role in early diagnosis of acute kidney injury. Recent studies on the favourable effects of Dexmedetomidine on cardiac surgery have been published. The aim of this study is to investigate whether there is a dose-dependent positive effect of Dexmedetomidine on neutrophil gelatinase-associated lipocalin levels and renal functions when used after CABG. ⋯ In our study, we found that Dexmedetomidine infusion for sedation after CABG under cardiopulmonary bypass can be useful in the prevention of kidney injury. Conventional renal function tests, including blood urea nitrogen, serum creatinine, urine output and creatinine clearance rate measurements typically may not detect the development of acute kidney dysfunction in the first 48-h postoperative period. Differences were detected in renal function in the early postoperative period and the development of acute kidney injury, as determined by measurements of blood NGAL levels, was significant and dose-dependent.

Comparative StudyThe validity of the original EuroSCORE and EuroSCORE II in patients over the age of seventy.
EuroSCORE II, despite improving on the original EuroSCORE system, has not solved all the calibration and predictability issues. We investigated the sensitivity, specificity and predictability of original EuroSCORE and EuroSCORE II system in elderly patients. ⋯ The original EuroSCORE and the EuroSCORE II risk models should be used with caution in patients aged 70 or older undergoing cardiac surgery in the modern era. Below the age of 70, both models are sensitive, specific and have good predictive power. Our work needs validation by other large groups.
