Filter by:The investigators test the hypothesis that oropharyngeal leak pressure and fiberoptic position differ between the size 2 LM Ambu AuraOnce and the LM Ambu AuraGain in non-paralyzed anaesthetized pediatric patients.
CT and MRI based measurements of the pediatric airway has changed the age-old cone shape concept of the pediatric airway and define airway shape as elliptical structure. The cone shape was based on the cadaveric measurements done by Bayeux in 1897 and described later by Eckenhoff in 1951. The present study is based on three-dimensional CT images of the airway column replicating the cylinders used by Bayeux for his cadaveric measurements. The purpose of this study was to determine the cone shape of the pediatric airway.
The goal of this study is to track the intraoperative changes that occur in the airways of patients undergoing 1) laparoscopic surgeries in the Trendelenburg position, and 2) spinal surgeries in the prone position, as well as the regression of these changes postoperatively. These surgeries are known to cause edema and swelling of the soft tissues of the head and neck, temporarily worsening airway anatomy, but there is little data quantifying these changes, and no studies have investigated the time course required for the airway to return to its baseline after extubation. This would be important clinical information given that airway management is always a major concern perioperatively. The investigators will test hypotheses by evaluating patients' airways preoperatively, immediately post-extubation, and at regular intervals thereafter using the Modified Mallampati Score class (MMS), in which a patient's airway is scored from class 1 to 4 (in which 4 indicates the highest likelihood of a difficult intubation) based on the visibility of the soft palate, uvula, and faucial pillars inside the oral cavity.
The study title "Clinical trial of comparative evaluation of the Modified Mallampati Score and Modified Mallampati Score along with Thyromental distance, Anatomical abnormality, and Cervical mobility (M-TAC) in Predicting Difficult Airway " was undertaken to evaluate prediction of difficult airway by comparing preoperative airway evaluation tests. Mallampati classification is the most used screening test for detection of difficult intubation it is a classification of oropharyngeal view. Other tests include sternomental distance, thyromental distance, Wilson risk sum score, upper lip bite test, protrusion of mandible, tooth morphology, head extension, mouth opening, body mass index, 3-3-2 rule and ultrasonography of neck soft tissue. We studied 200 adult ASA I & II patients of either sex, aged between 18-60 yrs undergoing elective surgery receiving general anesthesia. Modified mallampati classification had four grades & each grade was given a score, similarly thyromental distance (TMD), anatomical abnormality (AA) & cervical mobility (CM) was classified into three grades & each grade was given a score. For M-TAC individual scores were added.
This study will look at key performance indicators of 2 supraglottic airway devices in anaesthetised adults in a crossover manner.
Retromolar Intubation is a successful option for intubation in patients with an existing retromolar gap in the case that the conventional method fails. Therefore the investigators want to test if the retromolar gap is essential for performing the retromolar intubation technique.
Multicenter randomized trial centered on critically-ill tracheostomized patients, comparing two different decannulation protocols: 1. based on capping trials to decide decannulation, 2. based on the aspiration frequency to decide decannulation time. High-flow conditioned oxygen therapy will be applied to all patients through the tracheal cannula. In patients included in the suctioning frequency based protocol along the study period and in patients included in the capping trial protocol along periods out of capping trials.
The aim of the study is to compare the performance of two supraglottic airway devices (SGA), the new Ambu AuraGain and the LMA Supreme, in sixty female patients undergoing gynaecologic laparoscopy in the trendelemburg position. Primary outcome is the airway seal pressure. Secondary outcomes are ease of insertion, quality of ventilation, endoscopic view of the glottis, gastric tube passage and complications.
This study aimed to compare the advantages and disadvantages of LMA Supreme, LMA Classic and LMA Fastrach regarding ease of insertion, repositioning, insertion time, effects on hemodynamic parameters, provision of adequate and safe airway, and oropharyngeal and systemic complications.
Does spatial orientation of a novice in relation to a mannequin (supine vs upright) impact on the development of fiberoptic intubation skills? Is it necessary to teach both orientations or is the supine view transferable to the upright position? Which method demonstrates longer skill retention? The hypotheses: Both orientations must be practiced and the upright skill is harder to learn but is retained for longer.
