The college is happy that YBA is accepted well amongst all practitioners and postgraduates as a compendium of anesthesia developments. Like in the past, a serious effort is shown in selecting topics of international importance, reviewing the contents multiple times, and presenting it in the most readable format to attract all and widen the knowledge and skill.

ICA congratulates the Editors and Contributors to this eleventh yearbook and wishes you all an excellent career forward.

After a long, successful, and illustrious inning as editors of this popular book, Dr Raminder Saigal and Dr Anjan Trikha decided to hand over the editorial reins to a new editorial team. We express our gratitude to the management team of the ‘Indian College of Anaesthesiologists’ for believing in us and bestowing the responsibility of the book on us. The new team has made efforts to publish articles penned by pioneers and forerunners in various subspecialties of Anesthesiology. We hope to meet the high expectations of our readers.

Knowledge in the field of healthcare is dynamic. There is constant evolution in therapy, assessment, monitoring, and patient management modes to improve patient outcomes. For success in the field of medicine, there is a continual need to upgrade knowledge. Knowledge and technology in Anesthesiology and Critical Care are advancing at an incredible pace. It is challenging to keep pace with this progress. One needs to aggregate information from multiple journals, books, and online resources. This yearbook assimilates a large amount of data and facilitates the availability of this advanced knowledge in a precise manner.

The days of ‘Jack of All and Master of None’ are over. Today, the knowledge pool is exceptionally vast. We needed to identify Masters in different subject fields to bring forth the best and most credible learning. We are incredibly grateful to many internationally acclaimed academic leaders and authors for accepting to contribute to this edition of the book. The knowledge presented is diverse and covers recent developments in various subjects.

Online education has changed the spectrum of teaching and dissemination of knowledge. The easy sourcing of information is weaning professionals away from standard printed literature. The emergence of COVID and the consequent lockdown promoted this online sourcing of knowledge. Several start-up companies, run by young Turks, are offering professional teaching aids with easy access. The benefits of this web-based information are, however, not absolute. A significant shortcoming of this model is the absence of an expert to moderate and correctly present this plethora of knowledge. The knowledge offered by this media is usually fragmented and not comprehensive. Only an expert in a field can cover a subject comprehensively and succinctly. The success ‘mantra’ of the successive editions of the yearbook possibly lies in the comprehension of the book's chapters by experts.

We want to express our extreme gratitude to our respective families. They graciously sacrificed their family time to facilitate this book edition. They believe that we can enhance professional competence by sharing knowledge, and family commitments should not be stumbling blocks. We acknowledge the role of our colleagues who helped us in this endeavor. Lastly, we would fail in our duty if we do not express our gratitude to our patients, who are our most valuable teachers.
