Is it possible to look at any medical specialty through the eyes of another specialist? It is useful to look through the eyes of another specialist at a related specialty: this allows you to better know it, improve your own and exchange views with related specialists on problems common to the two specialties. And they themselves, "strangers," albeit related specialists, will improve their specialty on the basis of such an exchange, if they consider it necessary. In critical care medicine, which always includes anesthesiology entirely, and obstetrics - according to situational necessity, such a mutual examination is especially important.
