Epidural, Inadvertent Subdural, and Combined Epidural-Subdural Anesthesia in Lumbar Spine Surgery: A Retrospective Analysis.

This study aimed to categorize contrast media images associated with epidural, subdural, and combined epidural-subdural anesthesia in patients who had undergone fluoroscopy-guided epidural anesthesia using contrast media combined with monitored anesthesia care (MAC) targeted at deep sedation, incorporating capnography over 5 years. Additionally, a correlation was established between the anesthetic effects and radiographic findings according to the categorized imaging appearances. This study included 628 patients who underwent endoscopic, open, or fusion surgery under epidural anesthesia at Nanoori Hospital in Gangnam between March 2018 and September 2023.

The Comparison of Fluoroscopy-Guided Epidural Anesthesia with Conscious Sedation and General Anesthesia for Endoscopic Lumbar Decompression Surgery: A Retrospective Analysis.

Background: With advances and refinements in endoscopic lumbar spine surgery showing effective and satisfactory results, the need for simple yet effective anesthetic techniques for minimally invasive endoscopic spine surgery has increased. The aim of this study was to compare feasibility and postoperative outcomes of fluoroscopy-guided epidural anesthesia with general anesthesia in patients undergoing endoscopic lumbar decompression surgery (≤3 levels).

Methods: Patients who underwent 1-3 levels of endoscopic lumbar decompression surgery under either fluoroscopy-guided epidural or general anesthesia between January 2019 and October 2020 were retrospectively reviewed.

Advantages of the Combination of Conscious Sedation Epidural Anesthesia Under Fluoroscopy Guidance in Lumbar Spine Surgery.

Background: With the increase in life expectancy seen throughout the world, the prevalence of degenerative spinal pathology and surgery to treat it has increased. Spinal surgery under general anesthesia leads to various problems and complications, especially in patients with numerous medical comorbidities or elderly patients. For this reason, there is a need for safer anesthetic methods applicable to unhealthy, elderly patients undergoing spinal surgery.

Contact and fumigant toxicity of oriental medicinal plant extracts against Dermanyssus gallinae (Acari: Dermanyssidae).

The acaricidal activity of methanolic extracts from 40 oriental medicinal plant species and a steam distillate of Cinnamomum camphora towards poultry house-collected adult Dermanyssus gallinae De Geer was examined using direct contact and vapour phase toxicity bioassays. Results were compared with those of 15 acaricides currently used. In filter paper contact toxicity bioassays using adult D.
