ReviewLasting effects of general anesthetics on the brain in the young and elderly: "mixed picture" of neurotoxicity, neuroprotection and cognitive impairment.
General anesthetics are commonly used in major surgery. To achieve the depth of anesthesia for surgery, patients are being subjected to a variety of general anesthetics, alone or in combination. It has been long held an illusory concept that the general anesthesia is entirely reversible and that the central nervous system is returned to its pristine state once the anesthetic agent is eliminated from the active site. ⋯ The vulnerability of aging brain to general anesthetics, specifically in the context of cognitive disorders and Alzheimer's disease pathogeneses are also discussed. Moreover, we will review emerging evidence regarding the neuroprotective property of xenon and anesthetic adjuvant dexmedetomidine in the immature and mature brains. In conclusion, "mixed picture" effects of general anesthetics should be well acknowledged and should be implemented into daily clinical practice for better patient outcome.

Handover of anesthesia care is associated with an increased risk of delirium in elderly after major noncardiac surgery: results of a secondary analysis.
In patients undergoing major surgery, complete handover of intraoperative anesthesia care is associated with adverse postoperative outcomes including high mortality and more major complications. The purpose of this study was to explore the association between the intraoperative complete handover between anesthesiologists and the occurrence of postoperative delirium. This was a secondary analysis of the database of a previously published clinical trial. ⋯ Patients with intraoperative complete handover also had higher incidence of non-delirium complications (P = 0.003) and stayed longer in hospital after surgery (P = 0.002). For elderly patients admitted to the intensive care unit after noncardiac surgery, intraoperative complete handover of anesthesia care was associated with an increased risk of postoperative delirium.

Factors affecting phantom limb pain in patients undergoing amputation: retrospective study.
The efficacy of preemptive analgesia for prevention of phantom limb pain has been controversial although pain management before amputation is empirically important. The aim of this study was to determine the associated factors with perioperative phantom limb pain. ⋯ The types of anesthesia and the degree of postoperative pain were not related to the development of phantom limb pain. The present data suggest that insufficient preoperative pain with NSAIDs and diabetes mellitus would give an impact on the development of phantom limb pain.

Practice GuidelineGuidelines for the use of cerebral oximetry by near-infrared spectroscopy in cardiovascular anesthesia: a report by the cerebrospinal Division of the Academic Committee of the Japanese Society of Cardiovascular Anesthesiologists (JSCVA).
Cerebral Oximetry by Near-infrared Spectroscopy (NIRS) has been used in cardiovascular anesthesia, but there was no guideline of regional cerebral oxygen saturation measured by cerebral oximetry by NIRS. This guideline provides recommendations applicable to patients at a risk of developing cerebral ischemia in cardiovascular surgery. Guidelines are intended to define practices meeting the needs of patients in most, but not all, circumstances, and should not replace clinical judgment. ⋯ Adherence to recommendations could be enhanced by shared decision making between healthcare providers and patients. This guideline was focused on cerebral oximetry of pediatric and adult cardiovascular disease. We hope this guideline would play an important role in using cerebral oximetry by measured NIRS.

Prophylactic sivelestat for esophagectomy and in-hospital mortality: a propensity score-matched analysis of claims database.
Transthoracic esophagectomy is an invasive surgery, and the excessive surgical stress produces inflammatory cytokines, which provoke acute respiratory distress syndrome (ARDS). Sivelestat sodium hydrate-a selective neutrophil elastase inhibitor-is used to treat or prevent ARDS in patients undergoing esophagectomy, although clear evidence is lacking. We investigated the benefits and risk of prophylactic sivelestat. ⋯ Because mortality and postoperative complications were similar, our findings do not support prophylactic sivelestat administration for patients undergoing esophagectomy.
