Clinical trials

This prospective, multicenter observational study aims to evaluate the effect of different flow rates of high-flow nasal oxygen (HFNO) on the quality of the laryngoscopic view during videolaryngoscopy in adult patients undergoing general anesthesia. Each patient will serve as their own control, with repeated measurements obtained at three different HFNO flow settings (0, 40, and 60 L/min). The study will assess objective and subjective parameters of glottic visualization using standardized scoring systems.

We prospectively enrolled patients with a thoracic or lumbar spine fracture indicated for instrumented posterior stabilization. We consequently randomized the patient for either a conventional open approach procedure or minimally invasive surgery. 3DGA analysis was carried out at specific time points after surgery together with electromyography of deep-plane back muscles.

This prospective multicenter observational study aims to evaluate the agreement between artificial intelligence (AI)-based interpretation and expert interpretation of rotational thromboelastometry (ROTEM) findings in clinically relevant settings. ROTEM is widely used to guide hemostatic therapy in perioperative and critically ill patients, but its interpretation is complex and subject to interobserver variability. The primary objective is to determine whether AI-based interpretation achieves agreement comparable to variability between expert clinicians. Secondary objectives include comparison of interpretation time, assessment of consistency of AI outputs, and evaluation of potential differences in clinical decision-making. ROTEM datasets will be independently assessed by multiple expert anesthesiologists and by an AI-based model using standardized input. Agreement between methods and variability of interpretation will be analyzed. The study aims to determine whether AI-assisted interpretation could serve as a reliable decision-support tool and reduce variability in ROTEM-guided clinical practice.

This prospective controlled clinical trial evaluates the effectiveness and safety of radial artery cannulation using the Seldinger technique under ultrasound guidance when performed by two different operator groups: experienced physicians and trained registered nurses. The study aims to determine whether a structured, competency-based training program enables nurses without prior experience in arterial cannulation to achieve comparable outcomes to physicians in terms of first-attempt success rate, procedural efficiency, and complication rates.

The goal of this observational study is to describe characteristics of catheter related thrombosis (CRT) that persists after catheter extraction in condition of intensive care unit. The main questions it aims to answer are: 1. What is the incidence of CRT that persists after catheter extraction in patients hospitalized in the intensive care unit? 2. What are the risk factors for this phenomenon? 3. What is the fate of such a thrombus, including recanalization or the development of complications such as pulmonary embolism or post-thrombotic syndrome?

The goal of this study is to evaluate the performance of the new video laryngeal masks for securing airway in patients undergoing general anaesthesia. Main goal is to evaluate the first insertion attempt success rate, time to adequate ventilation, sealing pressures and adverse events.

This clinical study investigates a minimally invasive treatment called percutaneous transcatheter embolization of knee arteries for patients with chronic knee pain caused by advanced knee osteoarthritis or persistent pain after total knee replacement. Osteoarthritis of the knee is a common degenerative condition that can lead to long-term pain, reduced mobility, and decreased quality of life, and some patients do not achieve sufficient relief with standard treatments. The study is based on the hypothesis that targeted embolization of small arteries supplying the inflamed tissues of the knee can safely reduce abnormal blood flow associated with inflammation, leading to pain relief and improved knee function. During the procedure, a thin catheter is guided through the blood vessels to the affected area of the knee, where a temporary embolic agent is administered to reduce pathological blood supply. The aim of the study is to evaluate the safety and effectiveness of this procedure by assessing changes in pain intensity, knee function, and quality of life over a follow-up period of up to 24 months. The results of this study may help determine whether this minimally invasive approach can offer a new treatment option for patients who have limited alternatives for managing chronic knee pain

This questionnaire-based study aims to evaluate the adherence to and current clinical practices regarding intraoperative lung-protective ventilation (IOLPV) among anesthesiologists in the Czech Republic. Despite the established role of IOLPV in reducing postoperative pulmonary complications in selected populations, its routine application during general anesthesia for elective surgeries remains variable. The survey focuses on identifying common ventilation strategies, attitudes toward lung recruitment maneuvers, tidal volume selection, use of PEEP, and awareness of existing recommendations. The results will provide insight into national practice patterns, perceived barriers, and educational needs, helping to inform future guidelines, training initiatives, and efforts to enhance patient safety and postoperative outcomes across Czech anesthesia departments.

Analgesia related to the administration of local anesthetic solution into the fascia of erector spinae muscle is mediated by the effect of local anesthetic on the posterior and lateral branches of the anterior part of the spinal nerve. Comparable analgesic efficiency after the administration of both nerve blocks would reject the widespread theory of the paravertebral site of effect of the local anesthetic in ESPB.
