Rujirojindakul et al identified risk factors for reintubation of a patient in the post-anesthetic care unit. These can help to identify a patient who may benefit from more aggressive management before and after extubation. The authors are from Prince of Songkla University in Thailand.
Patient selection: post-anesthesia care unit, ASA I to IV
Parameters:
(1) age in years
(2) COPD
(3) hypoalbuminemia (serum albumin < 4 g/dL)
(4) estimated creatinine clearance
(5) emergency surgery
(6) ASA status
(7) type of surgery
(8) duration of surgery in hours
(9) neuromuscular blocking agent used
