研究室紹介
Professor Jeong Min Sung's research lab specializes in perioperative medicine and surgical critical care, with a focus on optimizing outcomes in urological and abdominal surgeries. The lab investigates pharmacological interventions—such as PDE5 inhibitors and erythropoietin—to enhance postoperative recovery, particularly in erectile function and liver regeneration. It also explores anesthetic techniques and hemodynamic management to improve patient safety during general anesthesia, especially in high-risk populations. The lab integrates clinical trials with translational research to address functional recovery and physiological stability in surgical patients.

13Background: Nerve-sparing radical prostatectomy (NSRP) had to be performed because approximately 94% of patients are diagnosed with localized prostate cancer (PCa). Although NSRP is generally done to improve functional outcomes, erectile dysfunction (ED) is one of the most prevailing complications after radical prostatectomy (RP). Phosphodiesterase type 5 inhibitors (PDE5-Is) are the most well-known treatment agent for postoperative ED. This study aimed to assess the efficacy of PDE5-Is in patie
Background The induction of general anesthesia may cause hemodynamic instability. Remifentanil is often administered to suppress the hemodynamic response. We aimed to evaluate the effect of remifentanil infusion on the hemodynamic response to induction of anesthesia in hypertensive and normotensive patients. Methods Patients were divided into two groups: Group H (n = 102) were hypertensive patients and Group C (n = 107) were normotensive patients. During induction, all patients received 1 µg/kg
Erythropoietin and iron have individually shown beneficial effects on early-phase liver regeneration following partial hepatectomy (PHx); however, there are limited data on the combined effect on late-phase liver regeneration after PHx. Here we examined combined effects of recombinant human erythropoietin (rhEPO, 3,000 IU/kg) and iron isomaltoside (IIM, 40 mg/kg) on late-phase liver regeneration following PHx and investigated the possible underlying mechanism. Rats administrated with rhEPO showe
Abstract Background Proper mask ventilation is important to prevent air inflow into the stomach during induction of general anesthesia, and it is difficult to send airflow only through the trachea without gastric inflation. Changes in gastric insufflation according to mask ventilation during anesthesia induction were compared. Methods In this prospective, randomized, single-blind study, 230 patients were analyzed to a facemask-ventilated group (Ventilation group) or no-ventilation group (Apnea g
INTRODUCTION: Previous studies comparing the effects of general and regional anaesthesia on postoperative opioid use have focused primarily on the immediate postoperative period, with limited investigations into long-term outcomes. METHODS: This retrospective cohort study included 558,944 patients aged ≥ 18 y who underwent one of nine surgical procedures (thoracotomy; total hip arthroplasty; total knee arthroplasty; shoulder arthroplasty; transurethral resection of the prostate; inguinal hernia
RATIONALE: Liver transplantation is an increasingly common treatment for patients with liver cirrhosis or hepatocellular carcinoma. Liver transplantation in patients with heart disease can pose a significant challenge to the transplant teams. PATIENT CONCERNS: A 46-year-old woman was diagnosed with hepatitis B virus-related hepatocellular carcinoma 3 years ago and had received 3 times transarterial chemoembolization. DIAGNOSES: The patient was diagnosed as end-stage liver disease due to hepatoce
본 연구는 영유아 교사의 원내 교사학습공동체 참여에 관한 인식을 살펴보고 원내 교사학습공동체 참여가 영유아 교사의 교수효능감에 미치는 영향을 알아보는 것을 목적으로 한다. 이를 알아보기 위하여 어린이집에 근무하고 있는 영유아 교사 196명을 연구대상으로 2021년 3월 24일부터 4월 2일까지 자료를 수집 하였다. 수집된 자료는 기술통계분석, 중다회귀분석으로 처리하였고 본 연구에 대한 결과는 다음과 같다. 영유아 교사의 원내 교사학습공동체 참여에 대한 조사결과, 원내 학습공동체가 필요하다고 인식하고 있었다. 원내 교사학습공동체 참여는 영유아 교사의 전체 교수효능감에 25%의 설명력을 나타내는 유의미한 변인인 것으로 나타났다. 교수효능감의 하위요인별로 살펴보면 개인적 교수효능감에서는 16%의 설명력이 있으며 일반적 교수효능감에서는 15%의 설명력을 나타내어 유의미한 변인임을 밝혔다. 본 연구결과 영유아 교사의 원내 교사학습공동체 참여는 어린이집에서 어려움을 겪을 수 있는 교사들이 동료
Abstract Purpose Changes in thickening or hardening of blood vessel walls due to aging can hinder arterial catheter placement in elderly patients. We compared the dynamic needle tip positioning (DNTP) technique and the long-axis in-plane (LAIP) technique in elderly patients. Methods This study was conducted on elderly patients aged 75 years or older who underwent general anesthesia requiring placement of an arterial catheter. A total of 160 patients was randomly allocated to the DNTP group or LA
Background: Chronic opioid use has become a socioeconomic as well as a medical problem. This study aimed to identify risk factors and develop prediction models for postoperative chronic opioid use (PCOU).Methods: This retrospective cohort study used data from the Korean National Health Insurance Service (NHIS) between January 2008 and December 2018. Of 2 077 825 patients aged seven years or older who underwent surgery, survived at least one year, and had no additional surgeries, 1 108 119 were r
Abstract Background To update previous meta-analyses by evaluating the association between body mass index (BMI) categories (underweight, overweight, and obesity) and gallbladder cancer (GBC) risk, and to compare findings between earlier and more recent studies. Methods A systematic search of PubMed and Web of Science identified 10 observational studies published between January 2017 and May 2025. Studies reporting risk ratios (RRs), hazard ratios, or odds ratios with 95% confidence intervals (C
