About the Lab

Professor Won-gyun Son's research lab specializes in veterinary anesthesiology and pain management, with a focus on optimizing anesthetic techniques and enhancing patient outcomes in small animals. The lab investigates novel drug delivery systems, such as temperature-responsive hydrogels, to prolong regional anesthesia, while also exploring multimodal anesthetic protocols to reduce anesthetic requirements and improve hemodynamic stability. Key research directions include the development of advanced airway management techniques and the identification of peri-anesthetic metabolic changes, such as hyperglycemia, in non-diabetic dogs. The lab integrates clinical anesthesiology with translational research to improve safety and efficacy in veterinary surgical patients.

OBJECTIVES: To compare the duration of regional anesthesia of the pelvic limb using bupivacaine with and without a temperature-responsive hydrogel (TRH) in dogs. METHODS: epinephrine) to block the femoral and sciatic nerves bilaterally via ultrasound with nerve stimulation guidance. Bupivacaine was used on one pelvic limb (Bup treatment), and bupivacaine with TRH was used on the contralateral limb (Bup-TRH treatment). The nerve block was considered successful upon the absence of responses to pin

Modified retrograde intubation through the cricothyroid membrane in a cat with temporomandibular joint ankylosis
Dalhae Kim, Inhyung Lee, Won‐gyun Son
SJR Q1Veterinary Medicine and ScienceOA

A 6-month-old, 2.9-kg, male, Korean short hair cat was referred for inadequate mouth opening (4 mm), and condylectomy was scheduled for ankylosis of the left temporomandibular joint. Retrograde intubation via the cricothyroid membrane was planned since direct visualisation of the larynx was not possible. In dorsal recumbency, the cricothyroid membrane was punctured with an 18-gauge needle, and a J-tip guidewire, inserted via the needle, was advanced and identified at the mouth. A 6-Fr truncated

Objective To determine the incidence of intra-anesthetic hyperglycemia and identify associated risk factors in non-diabetic dogs undergoing general anesthesia. Study design Retrospective, single-center cohort study. Animals Four hundred client-owned, non-diabetic dogs anesthetized for surgical or diagnostic procedures between May and December 2024. Methods Medical records were reviewed to collect data on patient characteristics, anesthetic management, and intra-anesthetic blood glucose concentra

OBJECTIVES: This study aimed to evaluate the clinical effects of ethmoidal and maxillary nerve blocks during rhinoscopy in dogs. MATERIALS AND METHODS: Fourteen dogs underwent rhinoscopy. Under general anaesthesia with isoflurane, ethmoidal and maxillary nerve blocks were applied bilaterally using 2% lidocaine before rhinoscopy in eight dogs (EM group). Six dogs were premedicated with hydromorphone (0.05 mg/kg) as a substitute for local nerve block (H group). During rhinoscopy, the heart rate, a

Transient postoperative glycosuria after isoflurane exposure in two dogs

SJR Q1Journal of Small Animal Practice

The present report describes two surgical cases involving the development of sudden glycosuria after isoflurane anaesthesia, despite the dogs having normal blood glucose levels and renal glucose reabsorption. The glycosuria manifested 1 day after surgery and resolved spontaneously within 2 days in both cases. Considering that the surgeries (subcutaneous mandibular mass removal and fracture repair) were unrelated to the kidneys, and there were no remarkable events during anaesthesia, the glycosur

Opioid‐Induced Myoclonus During Premedication in Two Dogs With Hydrocephalus Proactively Managed With Antiepileptic Medications
Changhoon Nam, Inhyung Lee, Won‐gyun Son
SJR Q1Veterinary Medicine and ScienceOA

This report describes opioid-induced neurotoxicity (OIN) in two dogs with hydrocephalus undergoing the investigation of recurrent seizures; in both dogs, myoclonus occurred following premedication with butorphanol and remifentanil and resolved following the administration of midazolam. Thorough clinical evaluation excluded underlying systemic disease and increased intracranial pressure as possible causes, and opioid-induced modulation of gamma-aminobutyric acid (GABA) inhibitory and dopaminergic
