Randomized Controlled TrialEffect of cooled hyperbaric bupivacaine on unilateral spinal anesthesia success rate and hemodynamic complications in inguinal hernia surgery.
We hypothesized that cooling hyperbaric bupivacaine from 23 to 5 °C may limit the intrathecal spread of bupivacaine and therefore increase the success rate of unilateral spinal anesthesia and decrease the rate of hemodynamic complications. ⋯ Cooling of hyperbaric bupivacaine to 5 °C increased the density and viscosity of the solution and the success rate of unilateral spinal anesthesia, and decreased the hemodynamic complication rate.

Changes in presepsin concentrations in surgical patients with end-stage kidney disease undergoing living kidney transplantation: a pilot study.
Presepsin is a useful marker for differentiating sepsis from non-infection-related systemic inflammatory response syndrome. There are data describing elevated presepsin concentrations in patients with kidney dysfunction even in the absence of sepsis, but corresponding data for patients with end-stage kidney disease (ESKD) undergoing living kidney transplantation (LKT) are lacking. We investigated the changes in presepsin concentrations in this patient group in order to elucidate any relationship with renal function. ⋯ Presepsin concentrations consistently decreased after LKT. Moreover, presepsin concentration was strongly correlated with serum creatinine (r (2) = 0.72, n = 24, p < 0.001). These data suggest that the kidney clearly plays an important role in the metabolism and excretion of presepsin.

Case ReportsMonitored anesthesia care based on ultrasound-guided subcostal transversus abdominis plane block for continuous ambulatory peritoneal dialysis catheter surgery: case series.
Planning safe perioperative management for patients undergoing continuous ambulatory peritoneal dialysis (CAPD) catheter surgery (insertion and extraction of the catheter) is often difficult because many of these patients not only have renal insufficiency but also have co-existing disorders, such as heart diseases. As increased indications for perioperative anticoagulation therapy have limited the choice of anesthesia, selecting an appropriate anesthetic method, particularly for patients with poor systemic conditions, is becoming more challenging. ⋯ Despite co-existing cardiac disease and/or coagulation disorders, all patients were safely managed without any other major anesthetic methods. Subcostal TAP block is a useful anesthetic option for CAPD catheter surgery, particularly for patients with poor systemic conditions and/or in whom neuraxial blocks are contraindicated.

Case ReportsElectrical impedance tomography-guided prone positioning in a patient with acute cor pulmonale associated with severe acute respiratory distress syndrome.
Electrical impedance tomography (EIT) is a noninvasive technique used to assess regional gas distribution in the lung. We experienced a patient with acute cor pulmonale during high positive-pressure ventilation for the treatment of severe acute respiratory distress syndrome. Prone positioning was beneficial for unloading the right ventricle for treatment of acute cor pulmonale. ⋯ Timing of termination of prone positioning and ventilator settings such as lowering positive end-expiration pressure was determined to maintain dorsal recruitment as seen by EIT. The patient was weaned from mechanical ventilation on day 32 and discharged on day 200. EIT assessed the effects of prone positioning with real-time dynamic imaging and guided less injurious mechanical ventilation in a patient with acute cor pulmonale with dorsal lung derecruitment.

The efficacy of continuous subcostal transversus abdominis plane block for analgesia after living liver donation: a retrospective study.
Postoperative pain management for living liver donors has become a major concern as a result of the increasing number of living liver donations. Transversus abdominis plane (TAP) block has been known to provide effective analgesia for abdominal surgery. The aim of this study was to evaluate the efficacy of ultrasound-guided continuous subcostal TAP block as a part of a multimodal analgesic regimen in comparison with conventional intravenous (IV) fentanyl-based analgesia in living liver donors. ⋯ In conclusion, continuous subcostal TAP block provided an effective opioid-sparing analgesia for living liver donors.
