OBJECTIVES: Catheter malposition after subclavian venous catheterization (SVC) is not uncommon and can lead to serious complications. This study hypothesized that the left access is superior to the right access in terms of catheter malposition after ultrasound-guided infraclavicular SVC due to the asymmetry of the bilateral brachiocephalic veins. DESIGN: Parallel-armed randomized controlled trial. SETTING: A tertiary referral hospital in Korea. PATIENTS: Patients 20-79 years old who were schedul

Summary We studied the predictive performance of the Minto pharmacokinetic model during cardiopulmonary bypass in patients undergoing cardiac surgery. Patients received remifentanil target‐controlled infusion using the Minto model during total intravenous anaesthesia with propofol. From 56 patients, 275 arterial blood samples were drawn before, during and after bypass to determine the plasma concentration of remifentanil, and the predicted concentrations were recorded at each time. For pooled da

OBJECTIVES: Intraoperative ultrasonography (IOUS) offers the advantage of providing real-time imaging features, yet it is not generally used. This study aims to discuss the benefits of utilizing IOUS in spinal cord surgery and review related literature. MATERIALS AND METHODS: Patients who underwent spinal cord surgery utilizing IOUS at a single institution were retrospectively collected and analyzed to evaluate the benefits derived from the use of IOUS. RESULTS: A total of 43 consecutive patient

BACKGROUND: Cerebral vasospasm after aneurysmal subarachnoid hemorrhage (ASAH) is a serious complication and has a strong relationship with systemic inflammatory responses. Given previously reported relationships between leukocytosis and anemia with ASAH-related cerebral vasospasm, this study examined the association between the preoperative white blood cell-to-hemoglobin ratio (WHR) and postoperative symptomatic cerebral vasospasm (SCV) in patients with ASAH. METHODS: Demographic, preoperative

BACKGROUND: Major adverse cardiovascular and cerebrovascular events (MACCEs) after noncardiac surgery can lead to substantial morbidity, mortality, and health care costs. Therefore, accurate and rapid risk prediction is crucial for targeted perioperative management. This study aimed to develop and validate a minimally burdensome multimodal deep learning model integrating demographic data, the International Classification of Diseases (ICD)-10 procedure codes, and raw preoperative 12-lead electroc

BACKGROUND: Erector spinae plane block (ESPB) can has been used for analgesia after lumbar spine surgery. However, its effect on postoperative quality of recovery (QoR) remains underexplored in patients undergoing transforaminal lumbar interbody fusion (TLIF) or oblique lumbar interbody fusion (OLIF). This study hypothesized that ESPB would improve postoperative QoR in this patient cohort. METHODS: Patients undergoing TLIF or OLIF were randomized into ESPB (n=38) and control groups (n=38). In th

PURPOSE: Applying a cervical collar during videolaryngoscopic intubation can increase the lifting force required to achieve adequate glottic view, potentially increasing cervical spine motion. We aimed to compared cervical spine motion during videolaryngoscopic intubation between applying only the posterior piece (posterior-only group) and applying both the anterior and posterior pieces (anterior-posterior group) in patients wearing a cervical collar. METHODS: We conducted a dingle-centre, paral

BACKGROUND: Inflammation is involved in the pathophysiology of postoperative acute kidney injury (AKI). We investigated whether preoperative platelet-to-white blood cell ratio (PWR), a novel serum biomarker of systemic inflammation, was associated with postoperative AKI following cerebral aneurysm treatment. We also compared the discrimination power of preoperative PWR with those of other preoperative systemic inflammatory indices in predicting postoperative AKI. METHODS: Perioperative data incl

BACKGROUND: Strict blood pressure control can be used to prevent or treat cerebral hyperperfusion syndrome. This study investigated whether scalp nerve block (SNB) is associated with a reduced risk of postoperative symptomatic cerebral hyperperfusion syndrome (SCHS) by reducing postoperative blood pressure in adult patients who underwent combined revascularization surgery for moyamoya disease. METHODS: Patients were retrospectively divided into the SNB (n=167) and control (n=221) groups dependin

Background: Preoperative comorbidities are associated with postoperative acute kidney injury (AKI). However, whether this association is direct or mediated by intraoperative hypotension (IOH) is unclear. We hypothesized that IOH mediates the relationship between preoperative comorbidities and postoperative AKI. Methods: Data from adult patients undergoing non-cardiac surgery under general anesthesia were analyzed. Inverse probability of treatment weighting (IPTW) was applied to achieve a balance
