Observational StudyEffect of sensor location on regional cerebral oxygen saturation measured by INVOS 5100 in on-pump cardiac surgery.
Near-infrared spectroscopy sensors often cannot be attached at the commercially recommended locations because combined use of neurological monitoring systems is common during on-pump cardiac surgery. The primary purpose of this study was to compare the incidence of regional cerebral oxygen desaturation and regional cerebral oxygen saturation values detected using near-infrared spectroscopy between the upper and lower forehead during on-pump cardiac surgery. ⋯ Regional cerebral oxygen saturation was significantly lower at the upper than lower forehead during on-pump cardiac surgery. However, disagreements in detection of cerebral regional oxygen desaturation were only significant at 1 h after initiation of aortic cross-clamping.

Review Practice GuidelineJSA guideline for the management of malignant hyperthermia crisis 2016.
Malignant hyperthermia (MH) can be fatal if the crisis is not appropriately treated. It is an inherited disease usually triggered by the administration of volatile inhalational anesthetics and/or succinylcholine, a muscle relaxant. In a patient with suspected MH, the mechanism of calcium release from storage in the sarcoplasmic reticulum in the skeletal muscle is abnormally accelerated. ⋯ MH should be treated by discontinuation of the triggering agents, administration of intravenous dantrolene (initially 1 mg/kg), and reduction of the body temperature. Early diagnosis and sufficient dantrolene with body temperature reduction are essential to relieve the patient's MH crisis. This guideline in Japanese translation has been posted on the website: http://www.anesth.or.jp/guide/pdf/guideline_akuseikounetsu.pdf .

Randomized Controlled Trial Comparative StudyOral 30% glucose provides sufficient sedation in newborns during MRI.
Newborns are often sedated during MRI but sedation itself creates adverse events and management is more challenging in this environment. Oral glucose/sucrose administration has been studied in newborns during painful procedures; however, its effectiveness in keeping newborns sleepy and motionlessness during painless procedures has not been demonstrated. The objective of this study was to describe effectiveness of oral 30% glucose administration by comparing with intravenous midazolam sedation for newborns during MRI. ⋯ Oral 30% glucose administration for newborns during MRI is as effective as standard sedation protocol with midazolam. Thereby, we recommend and support the integration of this safe and reliable technique into routine practice for newborns during MRI.

Randomized Controlled TrialThe protective effect of human atrial natriuretic peptide on renal damage during cardiac surgery.
Acute kidney injury (AKI) is one of the critical complications after cardiac surgery. In the kidney, angiotensin II (Ang II) is formed by independent mechanisms, and activity of the intrarenal renin-angiotensin-aldosterone (RAAS) system contributes to the progression of kidney damage. Although atrial natriuretic peptide (ANP) exerts protective effects against renal injury by inhibiting the RAAS, the mechanisms of this effect have not been completely clarified. We investigated how human ANP (hANP) could prevent renal damage induced by cardiopulmonary bypass. ⋯ hANP demonstrated renal protective effects during cardiac surgery, and could possibly reduce the incidence of AKI after ischemia-reperfusion surgery. Moreover, this protective effect of hANP is likely induced by inhibition of the intrarenal RAAS.

The effect of esophagogastroduodenoscopy probe insertion on the intracuff pressure of airway devices in children during general anesthesia.
Given the size of the esophagogastroduodenoscopy (EGD) probe and the compressibility of the pediatric airway, the EGD probe may increase the intracuff pressure (IP) of an airway device. The current study evaluated IP changes during EGD examination under general anesthesia in pediatric patients. Following the induction of anesthesia, a laryngeal mask airway (LMA) or endotracheal tube (ETT) was placed without neuromuscular blockade. ⋯ The IP of the LMA or ETT increased during EGD probe insertion and remained elevated while the probe was in place. High IP may compromise mucosal perfusion resulting in a sore throat when using an LMA or the potential for airway damage if an ETT is used. Removal of air from the cuff and titration of the IP should be considered after EGD insertion.
