Filter by:The goal of this clinical trial is to compare the airway management effects of flexible reinforced laryngeal mask and endotracheal tube in childhood adenotonsillectomy. Participants will be randomly allocated to two groups: endotracheal tube group (ETT) and flexible reinforced laryngeal mask group (FLMA). For those in ETT group: they will be intubated after induction of anesthesia .For those in FLMA group: they will be put in flexible reinforced laryngeal mask after induction of anesthesia . The investigators will compare FLMA with ETT to see if flexible reinforced laryngeal mask can be used safely and effectively in childhood adenotonsillectomy，and if there will be less severe adverse events in FLMA.
Our study aimed to compare two different laryngeal masks, SaCoVLM™ Video Laryngeal Mask and blind placement with LMA Supreme, in adult patients undergoing short elective surgeries. The aim is to optimize the use of commonly used laryngeal masks in clinical practice and examine the differences in oropharyngeal leak pressures.
This study aims to three-dimensionally assess the changes in the airway morphology after anterior segment retraction using maximum anchorage.
Our study aimed to compare the manual placement, direct laryngoscopy and video laryngoscopy assisted placement techniques of LMA Proseal, a new generation laryngeal mask (LMA), and to find an effective placement technique that does not allow airway leakage in one go.
Rationale: Effective and fast topical anaesthesia of the upper airway is of paramount importance in awake (conscious) videolaryngoscopy of the airway in order to avoid patient discomfort. Different methods of anesthetizing the airway have been described. Conventional topical airway anaesthesia is not always effective due to non-optimal flow patterns and generation of ineffective local anaesthetic aerosols. Other methods of anaesthetizing the airway are more invasive. In order to optimize topical anaesthesia of the airway a soft mist spray device (Trachospray) for topical anaesthesia of the airway has been developed, in which optimal airflow patterns are obtained and local anaesthetic aerosols are generated which will reach the target zone for anesthetizing the airway. Objective: In this study, the Trachospray will be used for awake videolaryngoscopy, to evaluate its use, effectiveness and comfort level for patients and anaesthesiologist. Study design: Interventional study. Study population: 20 healthy human volunteers, ASA 1, 18-60 years old. Intervention: Subjects will be asked to inhale 4 ml lidocaine 4% via the Trachospray device Main study parameters/endpoints: Anaesthesia of the airway as evaluated with successful awake videolaryngoscopy with minimal discomfort for the subject. Nature and extent of the burden and risks associated with participation: Risk management on the Trachospray device shows that all user risks are mitigated and no residual risks remain for the use of the device. Testing of the device and the application of the device in daily practice has no additional risks than the present technique of performing anaesthesia of the airways.There may be some discomfort during the procedure, mainly airway irritation which may cause coughing or gag reflex.
Pediatric patients are exposed to increased risk during general anesthesia. A myriad of problems can be encountered in the pediatric population by misplaced endotracheal tubes. Especially, during one-lung ventilation (OLV) a right-sided or left-sided tube is inserted to facilitate the surgery. However, inadvertent tube use, caused by misinterpretation of the distances of the trachea and the main bronchi, may cause unintended hypoxemia, postoperative atelectasis and even mortality. In this study, investigators will measure the distance between distal margin of right lung upper lobe orifice-carina and carina-lip with the help of fiberoptic bronchoscopy (FOB).
The study was designed to evaluate the success rate, time of insertion, sealing efficacy and security of the Ambu® AuraGain in patients undergoing ambulatory surgery by one anesthetist
This study compares two intubation boxes, that is the Taiwan "Aerosol Box" versus the UMMC "Intubation Box". The importance of this intubation box has come to light recently in view of the COVID-19 pandemic and the fact that intubation is an aerosol-generating procedure. Risks of the healthcare worker attending to the airway of COVID-19 patients is high and the intubation box aims to minimize that and reduce contamination of the environment. The original design of the "Aerosol Box" has limitations and is not easily used by intubators. This study evaluates the clinical usefulness of an innovation of the "Aerosol Box" design that is made to be more ergonomic and increases the rate of successful intubation. Anaesthetists with more than 5 years of clinical experience in intubating airways as well as more than 20 successful intubations using videolaryngoscopy , will be available to participate. This study will employ manikin and will be a randomized cross-over trial, conducted in UM.
Cricothyroid membrane (CTM) localization is a critical step prior to emergent surgical airway access. Ultrasound-guided localization of the CTM on the skin of the neck had been suggested prior to induction of general anesthesia so that a marked entry point can be used to quickly establish emergent front of neck access if required. In this prospective observational study, the investigators aim to determine the potential for migration of the CTM markings in the sagittal plane during neck repositioning.
The study was designed to evaluate the success rate, time of insertion, sealing efficacy and security of the Protector Laryngeal Mask, a new second generation disposable supraglottic airway device, in patients undergoing elective surgery.
