How much are we justified in getting the photocopy of original books?
What psychology do we have that we do not mind spending any amount of money on entertainment, electronic gadgets, fashion, food or fiction books, but for professional books, we feel burdened in spending even a little amount which may be just a cost of popcorn at the multiplex or a burger meal at a fast food point. Do not we think that it is the same profession by which we are earning for entertainment, electronic gadgets, fashion, food or fiction books?
By doing this, are not we insulting our profession or in fact ourselves?
You being the most educated class of society, just think over it and decide.
Preface to the Sixth Edition
As we know that medicine is ever changing, anesthesia has seen rapid changes in the last few years. In this edition, I have tried my best to incorporate the most recent advances in drugs, equipment and techniques; Cardiopulmonary resuscitation (CPR) guidelines are based on American Heart Association (AHA) 2015 guidelines. All the chapters have been thoroughly revised and updated with addition of few new chapters; there have been significant changes in almost all chapters.
This edition has been divided into nine sections providing a basic knowledge of physiology and pharmacology related to anesthesia, anesthesia machine and equipment, various anesthetic drugs and techniques in normal subjects and patients suffering from medical ailments and subspecialty management. I hope that chapters on intensive care management and cardiopulmonary resuscitation will be very useful to students.
To make the revision easier at the last time where a student does not get enough time to read the whole subject, the most important points are presented in italics, and moreover, key points are given at the end of each chapter. Wherever possible, a summary of topics has been presented in tabulated form. However, I will sincerely advise the students to go through the whole text at least once.
Although every effort has been made to minimize the scope of error, but still no one is perfect in this world. So, minor grammatical errors may be overlooked, but any major error or controversy may immediately be brought to the notice of author/publisher either through e-mail address or in writing. My e-mail address is dryadavajay@rediffmail.com. We will be highly obliged and try to rectify the mistake or clear up the controversy as soon as possible.
I hope that this edition of the book would be of immense value in providing the basic knowledge of anesthesia to undergraduate students. I am sure that this book would not only help in solving the anesthesia questions, but also questions related to intensive care therapy, applied physiology and emergency medicine.
I thank M/s Jaypee Brothers Medical Publishers (P) Ltd., New Delhi, India, for their efforts in bringing out this book in this elegant shape.

Preface to the First Edition
Anesthesia is often the overlooked subject during undergraduation; however, the requirement of basic knowledge of anesthesia at undergraduate level has become necessary because of multiple reasons. Firstly, because of the increasing scope of this specialty which is not only restricted to operation theaters, but also to intensive care units, pain management and emergency medicine. Secondly, and also very importantly, the questions of anesthesiology asked in different postgraduate (PG) entrance examinations are not only increasing in number, but also getting tougher and can only be answered if the student is having reasonable knowledge of the subject.
To fulfill these requirements, I decided to write Short Textbook of Anesthesia.
In this book, I put my efforts to provide a comprehensive text keeping more focus on topics which are frequently asked in various pre-PG examinations.
One more point I kept in mind while writing this book was to take care of the controversies commonly encountered during preparation of pre-PG examination because of different values and criteria mentioned in different books. For example, the color of oxygen cylinder in India and in most of the countries is black, while in USA, it is green. A blood transfusion criterion in India is volume loss more than 20%, while in western countries, it is 25–30%. In my book, values and criteria which are applicable in India have been mentioned and wherever found necessary difference to western countries has also been mentioned. I would like to advise the students to abide by the Indian standards, at least in anesthesiology.
Any suggestions, criticisms and controversies which can really help in improving this book are most welcome.
I wish best of luck to all the students appearing for the various pre-PG examinations.
Ajay Yadav
Acknowledgments
First of all I would like to thank my teachers at PGIMS, Rohtak, Haryana, India, who enabled me to do my undergraduation.
I wish to express my sincere thanks to my first teachers Dr Neelam and Dr Meenakshi, SMS Medical College, Jaipur, Rajasthan, India, from whom I learned the ABC of anesthesia.
I would be failing in my duty if I do not express my gratitude to my eminent guide, Dr Vijender Sharma, under whom I not only did my thesis, but also learnt a lot about life. I have yet to come across a person gentler than him; whatever goodness I have, I owed it to him.
I would also like to thank my seniors, Dr Madhu Jain, Dr Madhu Dixit, Dr S Kumar, and my colleagues, at Hindu Rao Hospital, New Delhi, India, whose indispensable help led me to start this venture.
I feel pleasure in conveying my sincere thanks to Mr Nishant Bajaj, CEO and Dr Ragni Agrawal, Medical Director, W Pratiksha Hospital, Gurugram, Haryana, India, for providing such an excellent and encouraging academic atmosphere in the hospital.
I am very thankful to my department colleagues, at the W Pratiksha Hospital, the discussions with whom have really helped me in keeping update with recent advances.
I would like to pay my very special thanks to my wife Promila, who has been a constant source of inspiration for me every moment. I would also like to pay my thanks to my sons, Vasu and Eklavya, friends and family members, who always stood like pillars for me.
I would be failing in my duty if I do not express my thanks to all undergraduate students who have really inspired me to write this book.
And last but not least, I would like to thank M/s Jaypee Brothers Medical Publishers (P) Ltd., New Delhi, India, for their technical help and kind support without which this venture would have not been possible.
