Pain after laparoscopic cholecystectomy (LC) is multifactorial and usually not effectively treated. Rectus sheath block (RSB) has been proven to reduce the pain from midline abdominal incision surgery. We investigated preemptive analgesic effect of RSB LC.In this prospective, randomized, single-center trial, 200 patients undergoing LC were randomized into preoperative (pre-RSB) or postoperative (post-RSB) group. An ultrasound-guided was performed before skin in pre-RSB group closure post-RSB...

Background: Increasing evidence supporting the clinical effectiveness of cooled radiofrequency ablation (RFA) therapy for genicular nerves in patients with chronic knee osteoarthritis (OA) exists. However, no study has been conducted to eliminate potential influence a placebo effect associated this procedure. Therefore, we evaluated efficacy RFA compared sham procedure painful knees due OA. Methods: In double-blind, randomized, controlled study, participants were randomly assigned receive...

Summary Post‐induction hypotension is common and associated with postoperative complications. We hypothesised that pneumatic leg compression reduces post‐induction in elderly patients undergoing robot‐assisted laparoscopic prostatectomy. In this double‐blind randomised study, were allocated randomly to the group (n = 50) or control 50). intervention group, was initiated before induction of anaesthesia. 20 min after anaesthesia induction. The primary outcome incidence these groups. defined as...

Preservation of adequate perfusion pressures to the graft is a main focus intraoperative management during kidney transplantation. We undertook this study investigate incidence higher use inotropes in transplant recipients and identify patient outcomes preoperative variables related this. retrospectively analyzed 1053 patients who underwent transplantation at Asan Medical Center between January 2006 February 2012, stratified by their inotropic score ([dopamine] + [dobutamine] [epinephrine ×...

Abstract Individuals with myotonic dystrophy type 1 (DM1) reportedly have a higher risk of postoperative complications than those without DM1; however, factors related to perioperative in DM1 patients remain unclear. We aimed identify the that may be associated patients. reviewed medical records 256 from 1998 2018, among whom 42 (16.4%) had previously undergone 51 surgeries under general and regional anaesthesia. Among patients, 11 (21.5%) 13 including respiratory complications, sustained...

Background: The ganglion impar (ganglion of Walther) block has been used to manage coccygeal and perineal (perianal genital) pain due both benign malignant causes. However, the factors associated with successful responses are unknown. Therefore, in present study, we aimed identify independent patients chronic regions. Methods: From January 2008 December 2017, performed a retrospective review 106 who underwent block. Patients were considered responders if they reported decrease more than 50%...

The preemptive visceral analgesic effect of regional nerve block has not been adequately investigated to date. We evaluated the thoracic paravertebral (TPVB) in patients undergoing laparoscopic cholecystectomy (LC) whom pre-incisional rectus sheath (RSB) was used minimize somatic surgical pain.In this prospective, randomized, assessor-blind study, 70 scheduled for elective LC were randomly assigned pre-TPVB (n = 35) or post-TPVB group. Both groups received RSB, and group TPVB before skin...

Background: Cervical epidural block (CEB) is an effective intervention for managing cervical radicular pain.This study aimed to investigate the current status of performing CEB in South Korea.Methods: Pain physicians affiliated with Korean Society were asked complete anonymous questionnaires regarding between September and October 2022.The questionnaire consisted 24 questions assessing methods detail.Results: Of 198 surveys collected, 171 (86.4%) reported CEB.Among those, majority (94.7%)...

Background Cervical epidural steroid injection is associated with rare but potentially catastrophic complications. The contralateral oblique (CLO) view may be a safe and feasible alternative to the lateral (LAT) for fluoroscopic-guided cervical injection. However, evidence clinical usefulness of CLO lacking. We assessed in managing herniated intervertebral discs. Methods Patients were randomly assigned receive under LAT or at 50±5° degrees groups. primary outcome was needling time comparison...

Introduction Although the contralateral oblique (CLO) view at 50°±5° is clinically useful for cervical epidural access, no previous studies have confirmed its safety. This prospective observational study was conducted to assess safety profile, including risk of dural puncture, in fluoroscopically guided access using CLO view. Methods In view, incidence puncture investigated as primary outcome. Other intraprocedural complications, intravascular entry, subdural spinal cord injury and vasovagal...

Recent attention has been directed towards fatty infiltration in the cervical extensor muscles for predicting clinical outcomes several disorders. This study aimed to investigate potential association between multifidus and treatment response following interlaminar epidural steroid injection (CIESI) patients with radicular pain.The data of pain who received CIESIs March 2021 June 2022 were reviewed. A responder was defined as a patient numerical rating scale decrease ≥ 50% from baseline...

Introduction Stenotic thoracic ligamentum flavum hypertrophy can cause leg and/or low back pain similar to that caused by lumbar spinal stenosis. However, the spine may occasionally be overlooked in patients with pain. An accurate understanding of prevalence stenotic and its associated factors is necessary. Methods In this study, we reviewed whole-spine MRI scans who visited clinic complaining between 2010 2019. We analyzed overall according age group, sex, grade disc degeneration, level....

General anesthesia (GA) has been considered the anesthetic technique which most frequent leads to phantom limb pain (PLP) after a amputation. However, these prior reports were limited by small sample sizes. The aims of this study evaluate incidence PLP according various techniques used for amputation and also compare occurrence etiology using Korean Health Insurance Review Assessment Service large-scale demographic information.The claims patients who underwent reviewed analyzing codes...

Degenerative lumbar spondylolisthesis (DLS) is frequently associated with spinal stenosis (LSS) and conservative treatments such as epidural steroid injection do not have long-term benefits in LSS patients DLS. This study evaluated the effectiveness of percutaneous neuroplasty using a balloon catheter DLS.Patients' sex, age, body mass index, diabetes, hypertension, grading, pain duration, location, intensity, medications were retrieved from electronic medical records. At 1, 3, 6 months...

Smoking is clinically associated with high postoperative pain scores and increased perioperative analgesic requirements. However, the association between duration of smoking cessation opioid requirements remains unclear. Therefore, this study aimed to evaluate We retrospectively analyzed data 144 male patients who received intravenous patient-controlled analgesia (IV PCA) after laparoscopic distal gastrectomy gastroduodenostomy. All were divided into three groups: G0, nonsmoker; G1, smoker...

Several treatment modalities have been proposed for foraminal stenosis, but the options remain unsatisfactory. Previous studies shown that transforaminal balloon adhesiolysis may be effective in patients with refractory lumbar stenosis. However, a high iliac crest, catheter insertion difficult via conventional approach (particularly targeting L5-S1 foramen). It has reported an epidural can placed easily by contralateral interlaminar retrograde approach. Therefore, we applied this to crest....
