“I would pay at least double the cost for this handy little reference.”

Dr Jessica Otte, drottematic blog


junior residents, interns and medical students

In medical school, we learn a lot about diseases and the basis for their management. However, we are traditionally less exposed to apparently easy problems like pain, nausea or hypokalemia. Quite often, those issues are brought to the attention of the nursing staff in the evening. At that time, the treating team is away and you're on call, running all over the hospital.

MD on Call gives you tips on how to QUICKLY assess and manage (acutely) common problems so you can go on assessing the next patient, or to your room to get some well deserved sleep. -- it is NOT meant to replace a textbook --

MD on call is divided into 5 main sections:

• Issues • 26 frequent on call situations (including management of some specific conditions)

Abdominal Pain*
Acute Coronary Syndrome*
