Successful resuscitation from asystole induced by bupivacaine requires the reestablishment of a sufficient coronary flow (CF) quickly. This study was designed to test whether levosimendan was superior to epinephrine in the reestablishment of crucial coronary flows after bupivacaine-induced asystole. ⋯ Levosimendan is superior to epinephrine in producing higher CFs and faster recovery when reversing bupivacaine-induced asystole in the isolated rat hearts.

Case Reports
A case report of multiple anesthesia for pediatric surgery: 80 anesthesia applications in a period of 6 years.
The side and adverse effects of anesthesia and its neurotoxicity to children have become major concerns of anesthesiologists in recent years. Currently, no clinical trials have provided clear evidence indicating the suitable minimum age for a patient's first anesthetic application, importance of anesthesia duration, number of anesthetic applications or interval between two consecutive anesthesia applications. A very rare case concerning the side, adverse and neurotoxic effects of multiple anesthesia in a child is presented. ⋯ In our case, there were no permanent side or adverse effects due to multiple anesthesia. The minimal psychological and scholastic problems of our case were tied to frequent hospitalization by the pediatric psychiatry consultation.

Sevoflurane preconditioning induces brain ischemic tolerance, but the mechanism remains poorly elucidated. Nitration is an important form of post-translational modification in pathological signaling. This study was to investigate the role of thioredoxin-1 (Trx-1) nitration in neuroprotection effect induced by sevoflurane preconditioning in a transient stroke model in rats. ⋯ Ischemic stroke reduces Trx-1 activity via post-translational nitrative modulation in rats. Sevoflurane preconditioning induces brain ischemic tolerance and anti-apoptosis by partially preserving Trx-1 activity via inhibiting nitration.

Mortality in patients with acute respiratory distress syndrome (ARDS) remains high. These patients require mechanical ventilation strategies that include high positive end-expiratory pressure (PEEP). It remains controversial whether high PEEP can improve outcomes for ARDS patients, especially patients who show improvement in oxygenation in response to PEEP. In this meta-analysis, we aimed to evaluate the effects of high PEEP on ARDS patients. ⋯ For ARDS patients who responded to increased PEEP by improved oxygenation, high PEEP could reduce hospital mortality, ICU mortality and 28-d mortality. High PEEP does not increase the risk of clinically objectified barotrauma.
