This small book is aimed at the young surgeons who would like to know something about anesthesia while developing expertise in their own field. The topics and chapters have been chosen in such a way that it may be useful to the postgraduates in surgery as well as practicing surgeons. Preanesthetic assessment and preparation of the patient which would tell upon the ultimate outcome of surgery has been adequately dealt with. Without going deep into the subject, all the practical aspects are discussed with their clinical relevance. This will certainly help the surgeons to easily spot and identify the anesthesia-related problems in the perioperative period so that remedial steps could be taken without delay; and if necessary, call the anesthetic colleague for help.
