Risk factors associated with hypotensive bradycardic events during open shoulder surgery in the beach chair position.

Background: Shoulder surgery in the beach chair position frequently causes hypotensive bradycardic events (HBEs), which are potentially associated with an increased risk of cerebral hypoperfusion. Here, we aimed to investigate the incidence and characteristics of symptomatic HBEs that require pharmacological interventions, and to identify specific risk factors associated with symptomatic HBEs.

Methods: We retrospectively examined the records of all patients aged ≥ 18 years who underwent shoulder arthrotomy in the beach chair position between January 2011 and December 2018 at Samsung Medical Center.

Severe lumbar radiculopathy with epidural venous plexus engorgement in a morbidly obese pediatric patient: A case report.

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.

Driving Pressure during Thoracic Surgery: A Randomized Clinical Trial.

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 standard protective ventilation was associated with less postoperative pneumonia or acute respiratory distress syndrome.

Clinical effect of the proximity of epidural blood patch injection to the leakage site in spontaneous intracranial hypotension.

Background: Epidural blood patch (EBP) has been shown to be an effective treatment option for spontaneous intracranial hypotension (SIH). We investigated whether response to the EBP was related to the distance of the injection site from the leakage site in patients with SIH.

Methods: We reviewed patients with SIH who underwent EBP at a single hospital.

Impact of surgical approach on postoperative delirium in elderly patients undergoing gastrectomy: laparoscopic versus open approaches.

Background: Postoperative delirium is a frequent complication in elderly patients undergoing major abdominal surgery and is associated with a poor outcome. We compared postoperative delirium in elderly patients following laparoscopic gastrectomy (LG) versus open gastrectomy (OG).

Methods: In total, 130 patients aged ≥ 65 years with gastric cancer undergoing LG and OG were enrolled prospectively.

Effect of pre-warmed intravenous fluids on perioperative hypothermia and shivering after ambulatory surgery under monitored anesthesia care.

Purpose: The aim of this study was to evaluate the effects of pre-warmed (approximately 41 °C) intravenous fluids (IV) on perioperative hypothermia and postoperative shivering in female patients undergoing short, ambulatory urological surgery under monitored anesthesia care (MAC).

Methods: Patients between the ages of 35 and 80 years were randomly assigned to either the pre-warmed (n = 27) or the room temperature (n = 26) group. According to group allocation, either pre-warmed IV fluids that had been stored in a warming cabinet for at least 8 h or room temperature IV fluids were administered intraoperatively up to approximately 600-700 ml, including a bolus infusion of 10 ml/kg within 20 min.
