NCT05780385
The aim of this prospective randomized trail is to compare nasotracheal versus orotracheal intubation in critically ill patients. We aim to study: * required sedation depth * rate of spontaneous breathing * extend and possibility of physiotherapy * vasopressor and sedative drug doses Participants are randomized 1:1 to receive either nasotracheal or orotracheal intubation.
NCT05614414
Postoperative sore throat is a complication of orotracheal intubation. The aim of our study was to assess the impact of videolaryngoscopy on postoperative sore throat during the first 24 hours following surgery. This was a prospective, randomized study, over a period of 9 months. The investigators included 136 patients with non-difficult airway, classified ASA I to III and over 18 years old. The patients were randomized into 2 groups: the VL group including 70 patients intubated with direct laryngoscopy and the LD group including 66 patients intubated with videolaryngoscopy.

To determine the safe inspiratory pressure to prevent the occurrence of gastric insufflation during facemask ventilation using point-of-care ultrasonography of antrum 3. To compare the effectiveness and safety between video intubating stylet and video laryngoscope in the placement of tracheal tubes 4. To apply minimally invasive CO monitors in guiding goal-directed hemodynamic therapy and assess its impact on major complications and postoperative recovery
NCT04948359
Background and Aim: Cuffed endotracheal tubes with appropriate size, good cuff design and cuff pressure monitoring in pediatric patients can be used safely without increasing airway morbidity. Inflating the endotracheal tube cuff with more than normal volume may lead to decreased capillary blood flow and mucosal damage, while inflating the endotracheal tube cuff with less than normal volume may lead to an increase in the risk of inadequate ventilation and pulmonary aspiration. In this study, we aimed to determine an optimal cuff inflation volume to achieve safe cuff pressure (20-25 cm H2O) in cuffed endotracheal tubes with an inner diameter of 4.5, 5.0, 5.5 mm, which are commonly used in pediatric anesthesia clinical practice.
NCT05173220
Tracheal intubation in an out-of-hospital setting is a frequent and potentially difficult procedure. The risk of adverse events increases dramatically with the number of attempts. The failure rate of the first intubation attempt ranges from 5 to 32% and the risk factors are unclear. In recent study, the prevalence of a failed first intubation attempt was 31.4% \[95% CI = 30.2-32.6\] among 1546 patients managed in an out-of-hospital setting. In this multicenter study, our center (N=462) had a rate of 36% of failure of the first attempt. Seven variables were independently associated with a failed first intubation attempt. Some of the associated factors can be improved (operator training and experience), but most cannot. Moreover some of them can not be anticipated in this context. A randomized control trial performed in an emergency department and a prospective, observational, pre-post study design showed that systematic use of a bougie during the first intubation attempt improved the success rate. Our objective is to measure the impact of a modification of our intubation modalities introducing the incitation of the use of the bougie on the first intubation attempt in the prehospital setting.
NCT02966392
The purpose of the study is to determine whether automated cuff pressure control results in a reduction in the proportion of patients developing ventilator associated respiratory infections during their stay in intensive care.
NCT03486171
In prehospital emergency setting, tracheal intubation is a frequent procedure (8% of interventions). Its objective is to control and protect upper airways and to optimize ventilation and oxygenation in patients with life-threatening distress. Intubation is a technical procedure which is associated with few difficulties with, in rare cases, the impossibility to do it. There are specificities of the out-of-hospital emergency with some risk factors that have been recognized in this context as well as the impossibility of assessing predictive factors of difficult intubation linked to the patient. The objective of the investigators was to describe the quality of tracheal intubation in prehospital emergency setting.
NCT03471884
A novel nonintubated thoracoscopic technique is promising to enhance recovery after thoracic surgery. However, the effects of nonintubated technique on specific organ protection in not clear yet. In this randomized trial, the effect of nonintubated technique on lung function protection will be evaluated via PaO2/FiO2 ratio, oxidative stress and inflammatory cytokines serially in lung cancer patients undergoing thoracoscopic lobectomy.
NCT02671877
The aim of this study is the evaluation of preoperative transnasal fiberoscopy, as a possible predictor of difficult laryngoscopy and intubation during elective general anesthesia in an adult population. Transnasal fibercoscopy is a minimally invasive examination and is routinely performed during ENT evaluation; on the other hand, current strategies used to predict the ease of intubation are still not sufficiently sensitive and specific, and an unexpected difficult or failed intubation at the induction of general anesthesia is a seriuos, and potentially fatal, emergency in anesthesia. In literature, a correlation between anatomical and functional parameters highlighted by fiberoscopy and difficulty of laryngoscopy and intubation has never been demonstrated nor indagated. If proven, this might give the Anesthestiologist further information about the expected difficulty of laryngoscopy and intubation, guiding a different - and hopefully safer - anesthesiological strategy.
NCT01351259
Underinflation and overinflation of tracheal cuff are common in intubated patients, including those intubated with polyurethane-cuffed tubes. The aim of this study is to determine the efficiency of a pneumatic device in controlling cuff pressure.
NCT01215422
There are two new instruments on the market that anesthesiologists use when putting a breathing tube into the lungs of patients. The purpose of this study is to see how easily anesthesiologists can learn to use them in children.
NCT01369381
Current methods for endotracheal intubation in the presence of cervical spine (c-spine) instability are not evidence-based. This is so because the relationships between the forces applied during intubation (by the laryngoscope) and the resulting c-spine movement have not yet been quantitatively characterized. As a result, with the current level of knowledge, it is not known, and it is not possible to predict, which types of c-spine instability have the greatest risk of cervical spinal cord injury with intubation. This shortcoming makes it impossible to know which intubation devices and techniques are likely to be safest in the presence of c-spine instability. To address this critical lack of knowledge, the overarching purpose of the proposed research is to: 1) quantitatively relate c-spine movement that results from the forces applied to the peri-airway tissues during intubation (force-motion relationships), and 2) use these data to develop a mathematical model of the c-spine that will predict which types of c-spine instability result in the greatest amount of abnormal c-spine motion and associated spinal cord compression during intubation. This clinical study will utilize laryngoscope blades that are instrumented with a high resolution pressure mapping system to make high-resolution measurements of the forces and pressures of intubation while making simultaneous measurements of c-spine motion. In this study, study subjects will be intubated using both a conventional (Macintosh) laryngoscope and an alternative (Airtraq) laryngoscope. By using two different laryngoscopes, we, the investigators, will introduce forces of differing magnitudes and distributions to peri-airway tissues. The Airtraq does not require a direct line of sight to visualize the vocal cords, and among the various new alternative laryngoscopes it is the only one that has been shown to result in 30-50% less cervical motion than a conventional (Macintosh) laryngoscope. Accordingly, we hypothesize 1) 30-50% less force will be applied with the Airtraq laryngoscope than with the conventional (Macintosh) laryngoscope and 2) 30-50% less c-spine motion will occur with the Airtraq. By studying (intubating) each subject twice, any differences in the c-spine force-motion relationships between devices will be due to the devices themselves. By studying each subject twice, we can account for (and eliminate) differences among study subjects in c-spine biomechanical properties.
