Post-Anesthetic Care Unit
Pronunciation: PAK-yoo
Also written as: PACU — Post-Anesthetic Care Unit
A designated recovery area staffed by trained personnel where patients are monitored and managed following anesthesia until they meet established discharge criteria.
Full Definition
The post-anesthetic care unit (PACU), colloquially known as the 'recovery room,' provides the immediate post-operative environment for monitoring patients as anesthetic agents are metabolised and consciousness returns. In dental anesthesiology, particularly in office-based settings, a designated PACU area with appropriate monitoring equipment and trained staff is mandated by state dental board regulations. Documentation in the PACU includes vital signs, pain and sedation scores, emesis, oxygen requirement, and the Aldrete score used to determine readiness for discharge. Editors should use the full term on first reference and the abbreviation PACU thereafter, noting that 'recovery room' is acceptable in semi-formal communications but not in regulatory filings.
Usage
Usage note: Preferred abbreviation is PACU; 'recovery room' is acceptable in semi-formal contexts but should be avoided in regulatory or medicolegal documents. Note: some sources spell 'post-anaesthetic' (British English); standardise per house style.
