Fluid management is the basis of all clinical management in neurosurgical patients. This is a complete book on transfusion practice in clinical neurosciences. It covers in detail the fluids and blood transfusion practice, also discussing the role of total parenteral nutrition in relation to neurologic patients. The importance of fluid management clinically can be seen as on one hand it plays a significant role in maintaining the hydration of the patient and on the other provides sufficient relaxation to the brain to facilitate surgery. The use of hyperosmolar therapy is unique to the practice of clinical neurosciences. Certain fluid types such as those containing glucose are detrimental to the brain. Likewise, large fluid shifts and blood loss are often observed during neurosurgical procedures. It is relevant to understand the physiology of blood and blood transfusion. This book covers all of these topics in their true relevance. It also provides an evidence-based practice of fluid administration for all neurologic patients including, pediatric and geriatric. The proposed book will be useful for trainees and clinicians in any field of clinical neurosciences. It would be very useful for residents and fellows pursuing their courses in neuroanesthesia, neurocritical care, neurosurgery, emergency medicine, anesthesia, and critical care. Fellows, Resident doctors, postgraduates, and even undergraduates would be benefited from this book. The book would be a ready-reckoner and useful during the clinical practice of physicians from varied specialties.
