WHAT WE ALREADY KNOW ABOUT THIS TOPIC: Driving pressure (plateau minus end-expiratory airway pressure) is a target in patients with acute respiratory distress syndrome, and is proposed as a target during general anesthesia for patients with normal lungs. It has not been reported for thoracic anesthesia where isolated, inflated lungs may be especially at risk. WHAT THIS ARTICLE TELLS US THAT IS NEW: In a double-blinded, randomized trial (292 patients), minimized driving pressure compared with sta

BACKGROUND: Surgery for gynecologic malignancy via midline-laparotomy leads to severe postoperative pain. Adequate pain control while sparing opioid consumption does offer benefits in postoperative complications and recovery. Intrathecal morphine (ITM) provides simple and effective analgesia. In this randomized trial, we compared postoperative opioid consumption in patients who received either ITM or a sham procedure. METHODS: We enrolled 68 adult patients undergoing open gynecologic oncology su

Abstract Background Patients are administered supplemental oxygen upon emergence from general anesthesia against the risk of hypoxia. However, few studies have assessed the weaning from supplemental oxygen therapy. This study investigated the frequency and risk factors of failure to discontinue supplemental oxygen at a postanesthesia care unit (PACU). Methods This retrospective cohort study was conducted in a tertiary hospital. We reviewed the medical records of adult patients admitted to the PA

Ultrasound-guided ESPB did not decrease total fentanyl equivalent consumption during the first 24 hour after open gastrectomy. It only reduced postoperative pain intensity until 3 hour postoperatively compared with the control group. Ultrasound-guided single-shot ESPB cannot provide an efficient opioid-sparing effect after open gastrectomy.

Despite the empirical use of human albumin during pancreatectomy to replace intraoperative volume loss while preventing fluid overload and edema, its impact on postoperative outcomes remains unclear. In addition, most previous studies have focused on the effects of therapeutic albumin usage. Here, we investigated whether preemptive administration of human albumin to prevent edema during pancreatectomy could reduce the incidence of moderate postoperative complications. Adult patients undergoing p

INTRODUCTION: Engorgement of the epidural venous plexus (EVP) is a rare cause of nerve root impingement. Dilated epidural veins cause compression of the thecal sac and spinal nerve roots, leading to lumbar radiculopathy. PATIENT CONCERNS: Here we describe a case of severe lumbar radiculopathy in a 15-year-old morbidly obese boy. DIAGNOSIS: Enhanced lumbar magnetic resonance imaging revealed left sided L1-L2 disc protrusion and engorgement of the lumbar EVP, resulting in narrowing of the thecal s

Remimazolam is a recently developed anesthetic agent for general anesthesia and sedation. Currently, the optimal infusion rate for the induction of general anesthesia within two minutes remains unclear. We estimated the 50% and 90% effective doses (ED50 and ED90) of remimazolam required for loss of responsiveness within two minutes in adult patients using the up-and-down method. The starting infusion rate of remimazolam was 0.1 mg/kg/min and was increased or decreased by 0.02 mg/kg/min intervals

Patient’s cooperation and respiration is necessary in percutaneous radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). We compared the respiratory patterns of dexmedetomidine and propofol sedation during this procedure. Participants were randomly allocated into two groups: the continuous infusions of dexmedetomidine-remifentanil (DR group) or the propofol-remifentanil (PR group). We measured the tidal volume for each patient’s respiration during one-minute intervals at five points

Corticosteroids have been empirically administered to reduce the rate of acute respiratory distress syndrome (ARDS) after esophagectomy. However, their efficacy remains controversial, and corticosteroids may increase the risk of graft dehiscence and infection, which are major concerns after esophagectomy. Therefore, we compared the incidence of composite complications (ARDS, graft dehiscence and infection) after esophagectomy between patients who received a preventive administration of corticost

BACKGROUND: A high fraction of inspired oxygen (Fio2) is administered during one-lung ventilation (OLV). However, a high Fio2 is not physiologic and may lead to various complications. We hypothesized that continuous titration of Fio2 using the oxygen reserve index (ORI) reduces oxygen exposure compared to conventional management during OLV. METHODS: In this randomized, double-blinded trial, patients undergoing thoracic surgery were assigned to an ORI (n = 64) or a control group (n = 60). In the

Many studies have reported that hypoalbuminemia could be associated with organ failure after liver transplantation. However, most of them focused on serum albumin levels measured at specific time points and not on the trend of serum albumin change. We investigated whether a cumulative postoperative change in serum albumin level up to postoperative day (POD) 5 is related to organ failure in patients who underwent living-donor liver transplantation (LDLT). Data of adult recipients who underwent LD
