Neuromonitoring is a tool of the trade in intensive care, and should incorporate cutting-edge technology with patience, repeated clinical observation, and careful identification of neuroworsening. The aim of the book is to be of practical use, and to assist the clinical practice of the busy physician. The clinical examination is the introductory section of the book, and an abundance of technology, with specific emphasis on the importance of intracranial pressure, follows. Since the patient with an injured brain can survive only if other organs and systems (such as the lungs, the acid-base equilibrium, etc.) are preserved, a section of the book covers the interactions between the affected brain and other organs. The intracranial pressure measurement starts (or unfortunately ends) with a well-maintained catheter, which becomes vital when the drainage of hydrocephalus is involved. Dealing with patients with severe brain damage has plenty of ethical implications, up to and including the problems related to brain death and organ donation.
