PURPOSE: Preoperative sleep study helps to predict post-adenotonsillectomy morphine requirements. However, in some institutions, many suspected children with obstructive sleep apnoea syndrome have an adenotonsillectomy without polysomnography assessments. This study investigated the relationship between the results of a fentanyl test performed before extubation and the postoperative morphine requirements in children after adenotonsillectomy. METHODS: Intravenous fentanyl (1 µg/kg) was given as a test before extubation when spontaneous ventilation was restored in 80 children aged 3-7 years who underwent adenotonsillectomy...

Ventilation with large tidal volumes (V T), greater than 10 ml/kg of predicted body weight (PBW), is associated with worse outcomes in critically ill and surgical patients. We hypothesized that the availability of quick reference cards with proposed V T ranges specific to gender and different heights would reduce the intraoperative use of large V T during prolonged abdominal surgery. We compared retrospectively the incidence of median V T used during prolonged (≥4-h-long) abdominal surgery before ("before") and after ("after") the quick reference V T cards were made available in all anesthesia machines in operating rooms of a single academic US medical center...

Respiratory management during general anesthesia aims to safely secure the airway and maintain adequate ventilation to deliver oxygen to the vital organs, maintaining homeostasis even during surgery. Despite its clinical importance, anesthesiologists often encounter difficulties in properly managing respiration during the perioperative period, leading to severe respiratory complications. In this year's JA symposium, 5 editorial board members of Journal of Anesthesia (JA) who are experts in the field of respiratory management in anesthesia discussed the following topics: quitting smoking before surgery: exposure to passive smoke is damaging to children, ventilator-associated pneumonia, high inspiratory oxygen concentration and lung injury, aspiration pneumonia, and postoperative respiratory management strategy in patients with obstructive sleep apnea...

BACKGROUND: Neuropeptide S (NPS) is an endogenous neuropeptide controlling anxiolysis, wakefulness, and analgesia. NPS containing neurons exist near to the locus coeruleus (LC) involved in the descending anti-nociceptive system. NPS interacts with central noradrenergic neurons; thus brain noradrenergic signaling may be involved in NPS-induced analgesia. We tested NPS analgesia in noradrenergic neuron-lesioned rats using a selective LC noradrenergic neurotoxin, N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4)...

PURPOSE: Current analgesic strategies for propofol injection pain may cause adverse reactions during electroconvulsive therapy (ECT), such as shortening seizure duration. This study investigated whether dexmedetomidine could attenuate propofol injection pain in ECT. METHODS: Participants were randomly allocated to receive 0.2 μg/kg dexmedetomidine (Dex-0.2 group), 0.5 μg/kg dexmedetomidine (Dex-0.5 group) or saline (control group) prior to ECT. The composite pain scale and objective Surgical Pleth Index (SPI) were used to measure the intensity of injection pain, and the percentage of patients with pain score > 2 was the primary outcome...

BACKGROUND: The underlying mechanisms of propofol-induced neurotoxicity in developing neurons are still not completely understood. We examined the role of PTEN-induced kinase 1 (Pink1), an antioxidant protein, in propofol-induced apoptosis in developing neurons. MATERIALS AND METHODS: Primary hippocampal neurons isolated from neonatal Sprague-Dawley rats were exposed to propofol 20 μM for 2, 4, 6 and 12 h. Subsequently, neurons underwent overexpression and knockdown of Pink1, followed by propofol exposure (20 μM, 6 h)...

PURPOSE: Routine preoperative pulmonary function tests (PFTs) are not recommended prior to low-risk surgery because their prognostic value is limited. However, only a few studies have assessed the utilization of healthcare resources regarding preoperative PFTs in a real-world setting. Here, we aimed to assess the prevalence and determinant factors of preoperative PFTs before low-risk surgery in Japan. METHODS: In this retrospective cohort study, we used the nationwide insurance claims databases...

PURPOSE: We aimed to evaluate the effect of the intraoperative dexmedetomidine (DEX) on the incidence and severity of catheter-related bladder discomfort (CRBD) after non-urologic surgery. The secondary aim was to find the correlation between the levels of CRBD and postoperative pain sensation. METHODS: Adult male patients undergoing lumbar microdiscectomy were enrolled. Patients were randomized into two groups. After propofol administration, group D (n = 35) received DEX at a loading dose of 1 μg/kg over 10 min, followed by a continuous infusion of 0...

PURPOSE: Little information is available on the predictive ability of previously published pharmacokinetic models of dexmedetomidine in patients under spinal anesthesia. We evaluated nine published pharmacokinetic models that were constructed in different study settings. METHODS: Sixteen patients received dexmedetomidine infusions after spinal anesthesia according to the manufacturer's recommended regimen (6 µg/kg/h over 10 min followed by 0.2-0.7 µg/kg/h) or target-controlled infusion (initial target of 1...

PURPOSE: Data from animal experiments suggest that exposure to general anesthetics in early life inhibits neurogenesis and causes long-term memory deficit. Considering short operating times and the popularity of sevoflurane in pediatric anesthesia, it is important to verify the effects of short-period exposure to sevoflurane on the developing brain. METHODS: We measured the effects of short-term exposure (2 h) to 3%, 6%, or 8% sevoflurane, the most commonly used anesthetic, on neural precursor cells derived from human embryonic stem cells, SNUhES32...

BACKGROUND: Acute kidney injury (AKI) after cardiopulmonary bypass (CPB) is a well-known postoperative complication. Remifentanil, which is a commonly used ultra-short-acting opioid, has antiinflammatory and sympatholytic effects with improvement of microcirculation. METHODS: A retrospective study was conducted to clarify the effect of the use of remifentanil during CPB on the incidence of postoperative AKI. Patients who underwent valve surgery while under cardiopulmonary bypass between January 2012 and December 2014 in our hospital were enrolled in this study...

PURPOSE: Hypotension and decreased cardiac output (CO) are common adverse effects during anesthesia induction depending on the patient's pre-anesthetic cardiac condition. The aim of this study was to assess the ability of hydroxyethyl starch (HES) 130/0.4 to prevent hypotension and decreased CO during the induction of general anesthesia. METHODS: Ninety patients undergoing laparoscopic surgery were randomly divided into a HES group and a crystalloid group. Following the insertion of an intravenous line, fluid was administered to each patient at a rate of 25 ml/min using either crystalloid or HES 130/0...

We report three cases of implantation of the SureScan(®) system and magnetic resonance imaging (MRI) for investigating causes of pain. Although there were metal-induced artifacts on the MR images of 2 patients, the artifacts did not affect the images of structures that needed to be assessed to make the diagnosis. The SureScan(®) system enabled patients implanted with spinal cord stimulation devices to undergo MRI.
