Surgery Abbreviations

This list collects 798 surgery abbreviations — operating theatre, anaesthesia and surgical ward terms used in operation notes and perioperative charts. Every entry shows the full form and a plain-English meaning. One abbreviation can appear in several specialty lists when it is genuinely used in more than one area, and abbreviations with more than one common meaning get a row for each meaning. Terms flagged ⚠ Error-prone are on recognised error-prone lists: write them out in full wherever possible.
