Risk models for patients undergoing robotic surgery, minimal invasive heart surgery and open-heart surgery

In this study; we tried to compile risk scoring systems (Original EuroSCORE, EuroSCORE II and STS) used in robotic surgery, minimally invasive cardiac surgery and open-heart surgery in the context of the literature.As a result, literature study of risk scoring systems in the robotic surgery was not found. In minimally invasive cardiac surgery, few studies are available. The effectiveness of existing risk scoring systems has not been established in these studies. Therefore, further investigations are required for developing risk scoring systems in robotic surgery and minimally invasive cardiac surgery. In open heart surgery, there is still no gold standard scoring system in all populations. Due to the increased case diversity, we believe that the commonly used risk scoring systems must be updated. Widely used risk-scoring systems are not effective in minimally invasive cardiac surgery and this is supporting our idea. Each clinic should choose the appropriate risk scoring system according to their own experience and case diversity. [Med-Science 2018; 7(4.000): 959-61

"Overtime Hours Effect" on Emergency Surgery of Acute Type A Aortic Dissection

Abstract Objective: Treatment of acute diseases of the aorta is still associated with high mortality and morbidity. It is believed that interventions for these diseases on overtime hours (night shifts or weekend shifts) may increase mortality. In this study, we investigated the effect of performing acute type A aortic dissection surgery on overtime hours in terms of postoperative outcomes. Methods: 206 patients who underwent emergency surgery for acute type A aortic dissection were retrospectively evaluated. Two groups were constituted: patients operated on daytime working hours (n=61), and patients operated on overtime hours (n=145), respectively. Results: Chronic obstructive pulmonary disease and repeat surgery were higher in group 1. There was no statistically significant difference between the two groups in terms of operative and postoperative results. Mortality rates and postoperative neurological complications in group 1 were 9.8% and 13.1%, respectively. In group 2, these rates were 13.8% and 12.4%, respectively (P=0.485 - P=0.890). Multivariate analysis identified that cross-clamp time, amount of postoperative drainage, preoperative loss of consciousness and postoperative neurological complications are the independent predictors of mortality. Conclusions: As the surgical experience of the clinics improves, treatment of acute type A aortic dissections can be successfully performed both overtime and daytime working hours

Which Distant Organ is Most Affected by Lower Extremity Ischemia-Reperfusion?

Background: It has been experimentally shown that reperfusion injury occurs in many remote organs after ischemia-reperfusion (I/R) of the lower extremity. However, which distant organ is affected more after I/R of the lower extremity has not been investigated. In this study, we investigate which remote organ is predominantly affected after lower extremity I/R
