Introduction
Presently, I'm working on a project to find a new method that can instantaneously detect the correct placement of the endotracheal tube in the trachea. Apart from that I'm busy with my book about airway management that would take some time before being published.Fortunately, my book titled," Airway management" got published with Springer publishers in Switzerland in Sept. 2014. My new book, “ Challenging topics in neuroanesthesia and neurocritical care” also got published with Springer publishers in Switzerland in 2017. This book tackles all the controversial subjects in the field by a team of renowned writers worldwide invited for the task with exquisite precision.The book was intended for neuroanesthesiologists, neurointensivists and emergency medicine specialists.
