Perioperative management of patients with coronary artery disease undergoing non-cardiac surgery: Summary from the French Society of Anaesthesia and Intensive Care Medicine 2017 convention.

This review summarises the specific stakes of preoperative, intraoperative, and postoperative periods of patients with coronary artery disease undergoing non-cardiac surgery. All practitioners involved in the perioperative management of such high cardiac risk patients should be aware of the modern concepts expected to decrease major adverse cardiac events and improve short- and long-term outcomes. A multidisciplinary approach via a functional heart team including anaesthesiologists, cardiologists and surgeons must be encouraged. Rational and algorithm-guided management of those patients should be known and implemented from preoperative to postoperative period.

Case 251: Nontraumatic Drug-associated Rhabdomyolysis of Head and Neck Muscles.

History A 21-year-old man with a history of abuse of multiple drugs and mild cognitive impairment who initially underwent treatment for excited delirium developed respiratory arrest shortly after admission and was successfully resuscitated. Unenhanced computed tomography (CT) of the head and neck and contrast material-enhanced CT of the chest, abdomen, pelvis, and complete spine were performed shortly after the initial treatment. Head and neck magnetic resonance (MR) imaging was performed 24 hours after admission. No other abnormalities were noted. There were no fractures, and there was no vascular injury in the head and neck region. The patient had no external neck injuries, congestion, or petechiae suggesting neck compression. He had no history of chronic or recurrent pain or skin rash. Urine testing was positive for cocaine, cannabis, and methamphetamine. Serum creatine kinase level was initially high (31 117 U/L [520 µkat/L]; normal, 1000 U/L [16.7 µkat/L]). Corrected calcium level was 2.22 mmol/L, and ionized calcium level was 1.09 mmol/L (lower end of the normal range). There was no acute renal failure at the initial phase, but serum creatinine levels reached 180 µmol/L 24 hours after admission, and creatine kinase peaked at 61 000 U/L [1019 µkat/L]. Urine was initially red, but the patient was not tested for myoglobinuria.
