Reintubation in the ICU following cardiac surgery: is it more difficult than first-time intubation in the operating room?: A prospective, observational study
BACKGROUND After cardiac surgery, a patient's trachea is usually extubated; however, 2 to 13% of cardiac surgery patients require reintubation in the ICU. OBJECTIVE The objective of this study was to compare the initial intubation in the cardiac operating room with reintubation (if required) in the ICU following cardiac surgery. DESIGN A prospective, observational study. SETTING Department of Anesthesiology and Intensive Care Medicine, Clinical Hospital of Santiago, Spain. PATIENTS With approval of the local ethics committee, over a 44-month period, we prospectively enrolled all cardiac surgical patients who were intubated in the operating room using direct laryngoscopy, and who required reintubation later in the ICU. MAIN OUTCOME MEASURES The primary endpoint was to compare first-time success rates for intubation in the operating room and ICU. Secondary endpoints were to compare the technical difficulties of intubation (modified Cormack–Lehane glottic view, operator-reported difficulty of intubation, need for support devices for direct laryngoscopy) and the incidence of complications. RESULTS A total of 122 cardiac surgical patients required reintubation in the ICU. Reintubation was associated with a lower first-time success rate than in the operating room (88.5 vs. 97.6%, P = 0.0048). Reintubation in the ICU was associated with a higher incidence of Cormack–Lehane grades IIb, III or IV views (34.5 vs. 10.7%, P < 0.0001), a higher incidence of moderate or difficult intubation (17.2 vs. 6.5%, P = 0.0001) and a greater need for additional support during direct laryngoscopy (20.5 vs. 10.7%, P = 0.005). Complications were more common during reintubations in the ICU (39.3 vs. 5.7%, P < 0.0001). CONCLUSION Compared with intubations in the operating room, reintubation of cardiac surgical patients in the ICU was associated with more technical difficulties and a higher incidence of complications.
