Fig. 3. This figure shows the total length of time patients at five sites spent in recovery units (both the postanesthesia care unit [PACU] and the second-stage recovery unit [SSRU]) after ambulatory surgery. This information is first stratified by anesthetic procedure—general anesthesia versus monitored anesthesia care versus other anesthetic regimens. The information is further stratified according to the use (SA) or nonuse (non-SA) of only the short-acting, fast-emergence agents listed in table 2. Finally, the information is broken down according to those who bypassed the PACU, designated as Yes, and those who did not, designated as No. The box represents the median duration, first and third quartiles. The lines extend to the minimum and maximum durations.
