Through this book, we have tried to compile the various laboratory tests and parameters which are important for the paramedical graduates. We have presented the various important topics in a concise and oriented manner that are easy to comprehend for the students. It is a recommended reading for the trainees and laboratory physicians. It is an excellent source of biochemistry literature on current practices, indispensable for course review and examination.

Endotracheal intubation is an integral part of the anesthesiologist's contribution to patient care. It becomes an essential component of general anesthesia. The placement of an endotracheal tube in the trachea is an extremely noxious stimulus. In response to this stimulation, there is a significant rise in catecholamine levels.

The present study was designed to compare the effect of labetalol and esmolol on sympathomimetic response to laryngoscopy and endotracheal intubation in normotensive patients undergoing surgeries under general anesthesi
