We aimed to investigate the impact of comorbidity burden on mortality in patients with coronavirus disease (COVID-19). We analyzed the COVID-19 data from the nationwide health insurance claims of South Korea. Data on demographic characteristics, comorbidities, and mortality records of patients with COVID-19 were extracted from the database. The odds ratios of mortality according to comorbidities in these patients with and without adjustment for age and sex were calculated. The predictive value o

BACKGROUND: The long-term incidence of chronic postsurgical pain (CPSP) after thoracic surgery has not yet been reported. METHODS: We retrospectively reviewed the electronic medical records of 4218 consecutive patients who underwent thoracic surgery for lung cancer between 2007 and 2016. We evaluated the long-term incidence of CPSP after thoracic surgery at intervals of 3 months for 36 months. A Cox proportional hazard regression analysis was performed to investigate the predictors of CPSP after

Protective ventilation is a prevailing ventilatory strategy these days and is comprised of small tidal volume, limited inspiratory pressure, and application of positive end-expiratory pressure (PEEP). However, several retrospective studies recently suggested that tidal volume, inspiratory pressure, and PEEP are not related to patient outcomes, or only related when they influence the driving pressure. Therefore, this review introduces the concept of driving pressure and looks into the possibility

BACKGROUND AND OBJECTIVES: Epidural analgesia is the gold standard for post-thoracotomy pain management and can be started before or after surgical incision. This systematic review and meta-analysis investigated whether pre-emptive epidural analgesia before thoracotomy incision reduces acute and chronic post-thoracotomy pain in adults compared with epidural analgesia after incision. METHODS: We searched databases including MEDLINE, Embase, and CENTRAL for randomized controlled trials comparing e

Abstract Background Although the intraoperative alveolar recruitment maneuver (RM) efficiently treats atelectasis, the effect of F io 2 on atelectasis during RM is uncertain. We hypothesized that a high F io 2 (1.0) during RM would lead to a higher degree of postoperative atelectasis without benefiting oxygenation when compared to low F io 2 (0.4). Methods In this randomized controlled trial, patients undergoing elective laparoscopic surgery in the Trendelenburg position were allocated to low- (

OBJECTIVE: To compare the impact of propofol-based total intravenous anesthesia (TIVA) versus inhalational anesthesia (IA) on the overall survival following cancer surgery. BACKGROUND: The association between intraoperative anesthetics and patients' long-term outcomes following cancer surgery remains controversial. METHODS: This retrospective cohort study used nationwide data from the Korean National Health Insurance Service. Adult patients who underwent cancer resection surgery (breast, gastric

BACKGROUND: During induction of general anesthesia, it is common practice to delay neuromuscular blockade until the ability to deliver mask ventilation has been confirmed. However, the benefits of this approach have never been scientifically validated. We thus compared the early and late administration of rocuronium before and after checking mask ventilation to investigate the efficiency of mask ventilation and the time to tracheal intubation in patients with normal airways. METHODS: Patients (n

BACKGROUND: Mechanical power (MP), the rate of mechanical energy (ME) delivery, is a recently introduced unifying ventilator parameter consisting of tidal volume, airway pressures, and respiratory rates, which predicts pulmonary complications in several clinical contexts. However, ME has not been previously studied in the perioperative context, and neither parameter has been studied in the context of thoracic surgery utilizing one-lung ventilation. METHODS: The relationships between ME variables

BACKGROUND: An intervention to potentiate hypoxic pulmonary vasoconstriction may reduce intrapulmonary shunt and hypoxemia during one-lung ventilation. Previous animal studies reported that repeated intermittent hypoxic stimuli potentiated hypoxic pulmonary vasoconstriction, but no clinical study has examined the effects of this intervention on hypoxemia during one-lung ventilation. We thus performed a single-center, parallel-group, double-blind, randomized controlled trial to investigate whethe

BACKGROUND: Although nefopam has been reported to have opioid-sparing and analgesic effects in postsurgical patients, its effectiveness in video-assisted thoracoscopic surgery (VATS) is unknown. OBJECTIVES: This study aimed to investigate the opioid-sparing and analgesic effects of perioperative nefopam infusion for lung resection. STUDY DESIGN: Double-blinded randomized controlled trial. SETTING: Operating room, postoperative recovery room, and ward at a single tertiary university hospital. MET
