The journey to achieve perfect surgical prophylaxis

A new interval approach for setting the distance relay zones to achieve perfect selectivity and maximum sensitivity

In this paper, an interval approach is presented to achieve perfect selectivity and maximum sensitivity in distance relay zones, considering uncertainties. For this purpose, first, the uncertainties affecting the settings of the three zones of a distance relay are discussed. Then, by using the Monte-Carlo simulation, the uncertainties are modelled and the impedances seen by the distance relay a...

Vancomycin for surgical prophylaxis?

The increasing prevalence of methicillin-resistant Staphylococcus aureus (MRSA) has resulted in a reevaluation of the role of vancomycin for surgical prophylaxis. Two systematic reviews of randomized control studies have concluded that cephalosporins are as effective as vancomycin for the prevention of surgical site infections (SSIs). However, most of these studies were conducted more than 10 y...
