Thoracic epidurals remain the optimal method for providing postoperative analgesia after complex open abdominal and thoracic surgeries. However, they can be challenging to both place and maintain, as evidenced by a failure rate that exceeds 30%.1 Proper identification of the epidural space and accurate placement of the catheter are critical in order to deliver effective postoperative analgesia and avoid failure.2,3 This case series investigated the difficulty in correctly identifying the proper vertebral level for thoracic epidural catheter procedures when performed in the lateral decubitus position.

Case Reports
A Case Report of an Incidental Ultrasound Finding in a Suspected Malignant Hyperthermia Patient.
Malignant hyperthermia (MH) is a rare but life-threatening genetic disorder of the skeletal muscles triggered by inhalation anesthetics or succinylcholine. A 49-year-old female developed symptoms of MH shortly after a lumbar surgery. ⋯ On receiving dantrolene, her symptoms improved within 20 minutes; a subsequent ultrasound revealed no fasciculations. Although halothane contracture testing was not available, the fasciculations that resolved with dantrolene administration in a MH suspected patient opens up a new potential avenue of diagnostics.

Medium-chain acyl-CoA dehydrogenase (MCAD) deficiency is one of the most common fatty acid oxidation disorders. The choice of anesthetics and blood glucose management are crucial to prevent metabolic decompensation. A 5-year-old Japanese boy with MCAD deficiency was scheduled to undergo surgery for an inguinal hernia. ⋯ Anesthesia was induced and maintained with remimazolam, remifentanil, and intermittent rocuronium. No metabolic decompensation was observed. This case indicates the importance of a continuous intravenous glucose infusion, and that remimazolam can be the first-line anesthetic for a patient with MCAD deficiency.

Case Reports
Acute Intraoperative Hyperkalemia During Robot-Assisted Radical Cystectomy: A Case Report.
A 50-year-old man with muscle-invasive bladder cancer was scheduled for a robotic radical cystectomy. Four hours into the surgery, his electrocardiogram showed rhythm disturbances. Arterial blood gas analysis showed a serum potassium concentration of 6.6 mEq/L. ⋯ The procedure was completed after conversion to an open surgery. The postoperative serum potassium concentration was reduced to 4.6 mEq/L, and the patient was extubated. The remainder of his hospital stay was uneventful.

Complex regional pain syndrome (CRPS) poses a diagnostic and management challenge for many clinicians, particularly when disease symptomatology waxes and wanes. Monitoring symptom variations with digital and infrared thermal images allows for more accurate evaluation of disease progression overtime. ⋯ The images were instrumental toward establishing the initial diagnosis of CRPS, monitoring disease progression, and assessing response to treatment. We discuss the present understanding of infrared thermography in CRPS and advocate for its routine use at the beside.
