Case ReportsPeripheral nerve blocks as the sole anesthetic technique in a patient with severe Duchenne muscular dystrophy.
General anesthesia and central neuraxial blockades in patients with severe Duchenne muscular dystrophy are associated with high risks of complications, including rhabdomyolysis, malignant hyperthermia, hemodynamic instability, and postoperative mechanical ventilation. Here, we describe peripheral nerve blocks as a safe approach to anesthesia in a patient with severe Duchenne muscular dystrophy who was scheduled to undergo surgery. A 22-year-old male patient was scheduled to undergo reduction and internal fixation of a left distal femur fracture. ⋯ The patient underwent a successful operation using peripheral nerve blocks with no complications. In conclusion general anesthesia and central neuraxial blockades in patients with severe Duchenne muscular dystrophy are unsafe approaches to anesthesia because of hemodynamic instability and respiratory depression. Peripheral nerve blocks are the best way to reduce the risks of critical complications, and are a safe and feasible approach to anesthesia in patients with severe Duchenne muscular dystrophy.

Effects of landiolol on refractory tachyarrhythmia after total cavopulmonary connection: a retrospective, observational, cohort study.
The onset of tachyarrhythmia after the Fontan procedure (total cavopulmonary connection; TCPC) should be considered a medical emergency. Landiolol is an ultra-short-acting β1-selective blocker whose effect on tachyarrhythmia after TCPC is unclear. We evaluated the efficacy and safety of landiolol for tachyarrhythmia after TCPC. ⋯ Landiolol reduced the heart rate from 151.8 ± 23.2 at the start to 132.9 ± 20.0 at 1 h and 126.1 ± 24.9 at 2 h (P < 0.01 and P < 0.01, respectively), without blood pressure decrease (P = 0.235). Landiolol was effective in treating critical tachyarrhythmia without hemodynamic deterioration. We believe that landiolol is a promising option for postoperative tachyarrhythmia after the Fontan procedure.

Case ReportsAn alternative method to achieve one-lung ventilation by surgical pneumothorax in difficult lung isolation patient: a case report.
It is challenging to establish one-lung ventilation in difficult airway patients. Surgical pneumothorax under spontaneous breathing to obtain well-collapsed lung is a feasible method for thoracic surgery. A 76-year-old man with right empyema was scheduled for decortication. ⋯ This technique has never been applied into the management of difficult one-lung ventilation. By this method, we provide an ideal surgical condition with safer, less time-consuming, and less skill-demanding anesthesia. It would be an alternative choice for management of one-lung ventilation in the difficult lung isolation patient.

A detailed evaluation of the new acute kidney injury criteria by KDIGO in critically ill patients.
Two previous classifications of acute kidney injury (AKI) have shown that AKI is associated with increased mortality. In 2012, Kidney Disease Improving Global Outcomes (KDIGO) created new AKI criteria by combining the two previous classifications. However, such combination might cause inconsistency among each definition in the criteria. We have investigated all the definitions in the new KDIGO criteria. ⋯ AKI defined by the new KDIGO criteria was associated with increased hospital mortality. Although definitions in the KDIGO criteria seem to be appropriate because of the clear relationship between mortality and stage progression on the whole, several limitations may exist, especially in stage 3. Further research should be needed to clarify the validity of the KDIGO criteria and the detailed categories.
