NCT05902013
The aim of this study is to perform a pilot study investigating the first attempt intubation success rate differing between video laryngoscope nasotracheal intubation and direct laryngoscope nasotracheal intubation. The study population will consist of 60 neonates and infants with congenital heart disease less than 1 year of age who need nasotracheal intubation during general anesthesia for cardiac procedures. Standard nasotracheal intubation will be performed using either a video laryngoscope or direct laryngoscopy. Neonates and infants will be randomly assigned (1:1) to standard video laryngoscopy (with one of the following systems: Storz C-MAC Miller Video Laryngoscope, Karl Storz, Tuttlingen, Germany or Mc Grath Video Laryngoscope, Medtronic, Boulder,USA) or to direct laryngoscopy with one of the following blades: Miller or Macintosh (Heine, Hersching, Germany).
NCT06687395
Background: FONA (front of neck access) is a surgical airway management technique used in emergency situations, primarily as the "last option" when less invasive airway management methods have failed. The need for FONA is extremely rare, which makes regular training in this skill all the more important. Study Objective: The objective of this study is to test "skill retention" three to four months after training on different cricothyrotomy models. The goal is to demonstrate that there is no intolerable difference in skill retention, regardless of whether FONA training is conducted on a commercially available cricothyrotomy model or on a self-made model. Population: The study population consists of 42 participants who are randomly assigned to two groups. Study Design: All participants begin with the same theoretical input. Following this, they complete training on their assigned practice model before undergoing an initial evaluation. Three to four months after the first evaluation, a reevaluation takes place, this time without any prior training. Parameters: The primary outcome parameter of the study is the score achieved on the checklist. Secondary outcome parameters include the time from the start of the procedure to the first successful ventilation and subjective assessment using a Likert scale questionnaire. Possible associations between checklist results and factors such as year of training, prior experience, clinical experience, and individual items on the subjective assessment questionnaire will be presented graphically in an exploratory manner and quantified using appropriate correlation coefficients. Hypothesis: The study aims to show that there is no intolerable difference in skill retention, regardless of whether FONA training takes place on a commercially available cricothyrotomy model or on a self-made model. This would open up the possibility of using cost-effective and readily accessible practice models for effective skill training.
NCT05759299
According to WHO, more than 230 million major surgical procedures are carried out under general anaesthesia each year worldwide. Despite important technological advances, airway management remains a major challenge in anaesthesiology. Data from large perspective studies on current incidence of major peri-intubation adverse events are lacking in the anaesthesia setting, especially on outcomes such as peri-intubation cardiovascular collapse, severe hypoxemia, and cardiac arrest. These events are more common in case of difficulties with airway management so that first pass intubation failure significantly increase the risks. Moreover, it has been documented that even transient hypotension during general anaesthesia, may have long-term consequences and may be associated with a worse outcome in patients undergoing non-cardiac surgery. The primary aim of the study is to assess the current incidence of major adverse events during advanced airway management for anaesthesia in patients undergoing elective or emergency surgery and in the setting of nonoperating room anesthesia. The secondary aim is to assess the current practice of airway management during anesthesia worldwide. STARGATE Study will be a large international observational study recruiting all consecutive adult (≥ 18 years old) patients undergoing general anesthesia in operating room and outside operating room. Primary outcome will be a composite of cardiovascular collapse, cardiac arrest and severe hypoxemia.
NCT05201339
According to previous studies, head and neck rotation reduces the tongue from being rolled back by gravity, which resulted in increasing patency of the upper airway. Therefore, the purpose of this study is to verify whether head and neck rotation increases the first attempt success rate of i-gel™.
NCT06611917
This study evaluates the effectiveness of ultrasonographic measurements compared to traditional physical examination tests in predicting difficult airways. With no definitive gold standard for anticipating airway challenges, this research explores the diagnostic capabilities of newer, non-invasive techniques like ultrasonography-which is gaining popularity due to its ease of use and widespread availability-in the field of anesthesia. The study focuses on defining highly sensitive and easy-to-use ultrasonographic markers that could aid anesthesiologists, intensive care specialists, and emergency physicians in effective airway management.
NCT05783050
Sedoanalgesia is applied to patients during gastrointestinal endoscopy. Sedoanalgesia may cause respiratory depression and hypoxia in patients. During these procedures, patients should be given oxygen support to reduce the incidence of hypoxia.This study aimed to compare the efficacy and procedural performance of two different airway devices (Wei Nasal Jet Tube vs Nasal Cannula Oxygen Support) in Gastrointestinal Endoscopy
NCT06403696
Laryngospasm and post-extubation stridor are major postoperative airway difficulties in pediatric patients using tracheal tubes. These conditions are frequently caused by epithelium edema and anesthesia-related problems. Because it could reveal tracheal and laryngeal issues, ultrasound is an essential method for establishing the proper endotracheal tube size and minimizing difficulties. This research focuses on the use of ultrasonography to predict and understand pediatric postoperative airway complications.
NCT05190757
The purpose of this research is to compare if insertion of laryngeal mask airway (LMA) vs. use of face mask, will reduce the time needed to achieve adequate ventilation prior to insertion of the breathing tube.
NCT05680909
SaCo videolaryngeal mask airway is a novel third generation supraglottic device allowing for continuous observation of entrance to larynx via inserted in special channel videoscope connected with cable with external monitor. In obese patients airway management can be difficult so use of new devices that improve safety and potentially efficacy of airway management is indicated. In prospective observational study the SaCo VLM will be evaluated in terms of maintaining airway patency and effectiveness of intubation through it's lumen in morbidly obese scheduled for elective general surgery under general anesthesia.
NCT03462550
The Laryngeal Mask Airway is a supraglottic airway device that has been used in anesthesia for decades. Now the third generation (LMA Supreme) is commonly used. Recently the LMA Protector is manufactured. The primary hypothesis of this study is: the oropharyngeal leak pressure of the LMA Protector is 5 cmH2O higher than the oropharyngeal leak pressure of the LMA Supreme. Secondary outcome measures are: ease of insertion, fibreoptic position, ease of gastric tube placement. Differences between LMA Supreme and LMA Protector are: the LMA protector has a dual gastric drainage channel, LMA supreme one. For LMA protector, airway tube and cuff are 100% silicone, in LMA supreme the cuff is polivinylchloride. Silicone cuffs have shown to reduce risk of sore throat and achieve higher seal pressures. There are no aperture bars in the LMA protector (2 in LMA supreme). The tube of LMA protector is more flexible. An integrated cuff pressure indicator for single use airway management devices that enables continuous cuff pressure monitoring only in the LMA protector.
NCT03395782
Earlier studies has shown a correlation between older age and longer time for the rise in the end-tidal O2 concentration during pre-oxygenation. In this study the investigators aim to analyse this correlation more closely and investigate if the arterial partial pressure of oxygen (PaO2) as measured before the start of pre-oxygenation, with the patient breathing air, is a better predictor than age for estimating the time necessary for achieving the goal of pre-oxygenation.
NCT04623645
