NCT ID: NCT06058481 Completed - Clinical trials for Supraglottic Airway Device

Comparing the Clinical Performance of BlockBuster vs Proseal-LMA in Unparalysed Patients Undergoing General Anesthesia

Start date: July 31, 2019
Phase: N/A
Study type: Interventional

Patients aged 19 to 78 years with ASA status I-II scheduled for elective surgery under general anesthesia, were recruited and randomized into two groups, Group A (BlockBuster) and Group B (Proseal-LMA). Anesthesia induction for both groups was standardized with no paralysis given. Supraglottic airway (SGA) insertion (either Blockbuster or Proseal-LMA) was executed by a single experienced investigator. The investigator inserted the BlockBuster in Group A patients and the Proseal-LMA in Group B patients. These parameters were compared between the groups; the number of attempts, time taken to achieve successful insertion, oropharyngeal leak pressure (OLP), fiberoptic view of SGA position, hemodynamics changes and complications from the insertion.

NCT ID: NCT05783128 Recruiting - Airway Management Clinical Trials

The Effect of Different Methods of Airway Management on the Stomatognathic System: an Observational Prospective Study.

Start date: March 1, 2023
Phase:
Study type: Observational

The manipulations required during airway management and the different methods of establishing an airway (endotracheal intubation, supraglottic airway device etc) during anesthesia, as well as certain drugs used during anesthesia and sedation, may have an impact to the stomatognathic system. These effects can vary from a subtle temporomandibular joint disc displacement with reduction to the onset of temporomandibular disorders to previously healthy subjects.This observational prospective study aims at investigating the effect of different methods of airway management during anesthesia on the stomatognathic system (including temporomandibular joint, mastication muscles, occlusion etc).

NCT ID: NCT05705206 Completed - Pediatric ALL Clinical Trials

Feasibility and Accuracy of Core Temperature Measurements Using the Esophageal Temperature Probe Inserted Through the Gastric Lumen of Supraglottic Airway Device in Pediatrics

Start date: March 25, 2021
Phase:
Study type: Observational [Patient Registry]

In pediatric patients, the accuracy of body temperature measured with an esophageal temperature probe placed through the gastric lumen of the supraglottic airway device is investigated.

NCT ID: NCT05499754 Completed - Clinical trials for Intracranial Pressure Increase

Effect of Different Supralottic Airway Devicess on Optic Nerve Sheath Diameter

Start date: July 1, 2019
Phase:
Study type: Observational

Direct laryngoscopy and tracheal intubation are associated with increases in intraocular pressure (IOP), intracranial pressure (ICP), heart rate (HR), and blood pressure. The use of supraglottic airway devices (SADs) are known to be beneficial in overcoming the disadvantages of laryngoscopy and tracheal intubation, especially ocular and pressure stress responses. In recent years, it has been reported that ultrasonographic measurement of optic nerve sheath diameter (ONSD) can be used in the diagnosis of increased ICP. The aim of our study is to compare the effects of Proseal laryngeal mask airway (pLMA), Suprem laryngeal mask airway (sLMA) and I-gel on hemodynamic response and ONSD during insertion in adult patients.

NCT ID: NCT05201339 Completed - Clinical trials for Intubation; Difficult or Failed

Effect of Head-neck Rotation on I-gel™ Insertion

Start date: February 25, 2022
Phase: N/A
Study type: Interventional

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™.

NCT ID: NCT04652466 Not yet recruiting - Ultrasound Imaging Clinical Trials

Ultrasound Imaging to Validate I-gel Placement in pediatrıc Patients

Start date: December 15, 2020
Phase:
Study type: Observational

For nearly half a century, supraglottic airway devices (SGA) have been used in pediatric patients, which are more practical than face masks, facilitate oxygenation and ventilation without the need for endotracheal intubation, and less invasive than endotracheal tubes. I-Gel is a supraglottic airway management device introduced in 2007, made of a medical grade thermoplastic elastomer, designed to create a non-inflatable, anatomical seal in the pharyngeal, laryngeal and perilaryngeal structures that prevents compression trauma. Recently, the use of I-Gel has become popular in children undergoing surgery that does not require muscle relaxation. It is important to place an I-Gel in the most appropriate position in order to provide adequate ventilation and prevent complications such as mucosal injury, glottic ptosis, and gastric insufflation with potential aspiration. Successful placement is usually clinically assessed by a capnogram with endtidal carbon dioxide (ETCO2) value, visual examination and auscultation with appropriate chest elevation, absence of oropharyngeal leakage at 20 cm H2O peak inspiratory pressure. Although Fiberoptic Bronchoscope (FOB) is accepted as the preferred verification tool for direct visualization, some studies on I-Gel position using FOB reported that I-Gel placement should be repositioned in some children (12.8-49%). Ultrasonography (USG), which has recently entered the practice of upper airway examination, has become a valuable, non-invasive, simple and portable technology for evaluating airway management even in upper airway anatomy impaired by pathology or trauma. The aim of this study is to compare the use of USG with the FOB to evaluate I-Gel placement in pediatric patients. The primary endpoint is to compare the incidence of for I-Gel malposition between USG and FOB. Secondary endpoints are to find the correlation between I-Gel's USG and FOB-detected malposition and to determine the diagnostic performance of the USG.

NCT ID: NCT03643029 Not yet recruiting - General Anesthesia Clinical Trials

The Accuracy of the Performance and Placement Test for Predicting Supraglottic Airway Device (SAD) Position in the Hypopharynx as Confirmed With Video Laryngoscopy

Start date: September 2018
Phase: N/A
Study type: Interventional

The supraglottic airway device (SAD) is currently widely used in patients undergoing general anaesthesia as a method of securing the airway. The usage of SAD does not require the patient to be paralysed prior to insertion, as opposed to an endotracheal tube. Five tests have been recommend to ensure that the SAD can be used for advanced procedure after a blind insertion. These tests however are not confirmed with visual validation and hence the confirmation of optimal position can be misleading. This study is conducted to validate by video laryngoscopy the five recommended tests for confirming the placement and efficacy of a SAD, thus enabling its safe application in institutions with limited availability of video laryngoscopes. Subjects for this study will consist of patients scheduled for procedures under general anaesthesia in the University of Malaya Medical Centre (UMMC) who are amenable to supraglottic airway management.

NCT ID: NCT02260427 Completed - Clinical trials for Supraglottic Airway Device

A Comparison of the I-gel and Self-pressurised Air-Q Intubating Laryngeal Airway (Air-Q sp) in the Elderly Patients

Start date: September 2014
Phase: N/A
Study type: Interventional

Supraglottic airway devices (SADs) are well established in anesthetic practice. Among these devices, the i-gel has been typically widely used. The self-pressurised air-Q intubating laryngeal airway (air-Q sp) is newly developed supraglottic airway devices. It is a new single-use device that may optimise the airway sealing while reducing the potential for postoperative complications such as sore throat. The overall structure of the air-Q sp is similar to the original air-Q, except the inflatable cuff. The aim of this randomized trial was to compare the clinical performance of the i-gel and the air-Q sp in elderly patients
