The patients were considered as 'ready for discharge' from the recovery room when they had no pain, a calm status and a modified Aldrete score
The groups were compared with respect to secondary outcomes applicable to the PACU stay, which included: the need for airway support (defined as jaw thrust, insertion of nasopharyngeal, oropharyngeal or laryngeal mask airway or reintubation); the incidence of desaturation (which we defined by an oxygen saturation of less than 90% while receiving oxygen via Hudson mask); the time from arrival in PACU to eligibility for discharge (defined by an Aldrete score
(11) >9); and the time to actual discharge.
In the following the modified Aldrete score (17) of the patient was obtained to evaluate the possibility to bypass the recovery room.
In a large study covering 1580 patients, BIS monitoring failed to show a significant effect on the time to achieve an Aldrete score of 9 to 10 after extubation when compared to standard clinical practice (29).
In the PACU, a modified Aldrete score (11), QoR score, presence or absence of nausea, vomiting, headache, drowsiness or dizziness before discharge, and time to hospital discharge were recorded.
Patients with one or more postoperative symptoms (nausea, vomiting, headache, dizziness or drowsiness) took longer to reach an Aldrete score >9 than patients without symptoms (8 [1-28] vs 5 [0-35] min; P=0.
