Anesthetic management with subcostal transversus abdominis plane block in recessive dystrophic epidermolysis bullosa for peritoneal dialysis catheter replacement : a case report

Background: Recessive dystrophic epidermolysis bullosa (RDEB) is a rare, hereditary mucocutaneous disorder that can involve renal insufficiency. If a vascular access for hemodialysis is unavailable, peritoneal dialysis can be utilized. This report describes an anesthetic management with ultrasound-guided transversus abdominis plane block (TAPB) in a patient with RDEB for peritoneal dialysis catheter replacement. Case presentation: A 49-year-old woman with RDEB needed to undergo peritoneal dialysis catheter replacement. As general, neuraxial and local infiltration anesthesia can lead to serious complications; we planned anesthetic management with subcostal TAPB as the primary analgesia modality. In the operating theater, surgery was initiated after performing left-sided subcostal TAPB. The patient complained of moderate pain at some points during surgery, and the pain was controlled with intravenous or local anesthetics without serious complications. Conclusions: In summary, subcostal TAPB could be a useful option for peritoneal dialysis catheter surgery in patients with RDEB

Subanesthetic ketamine exerts antidepressant-like effects in adult rats exposed to juvenile stress

Juvenile stress, like that caused by childhood maltreatment, is a significant risk factor for psychiatric disorders such as depression later in life. Recently, the antidepressant effect of ketamine, a noncompetitive N-methyl-d-aspartate receptor antagonist, has been widely investigated. However, little is known regarding its efficacy against depressive-like alterations caused by juvenile stress, which is clinically relevant in human depression. In the present study, we evaluated the antidepressant-like effect of ketamine in adult rats that had been subjected to juvenile stress. Depressive-like behavior was assessed using the forced swim test (FST), and electrophysiological and morphological alterations in the layer V pyramidal cells of the prelimbic cortex were examined using whole-cell patch-clamp recordings and subsequent recording-cell specific fluorescence imaging. We demonstrated that ketamine (10 mg/kg) attenuated the increased immobility time caused by juvenile stress in the FST, restored the diminished excitatory postsynaptic currents, and caused atrophic changes in the apical dendritic spines. Ketamine's effects reversing impaired excitatory/inhibitory ratio of postsynaptic currents were also revealed. These results indicated that ketamine could be effective in reversing the depression-like alterations caused by juvenile stress
