i-gel

Supraglottic airway devices such as laryngeal masks and i-gels are useful for airway management. The i-gel is a relatively new device that replaces the air-inflated cuff of the laryngeal mask with a gel-filled cuff. It remains unclear which device is more effective for neonatal resuscitation. We aimed to evaluate the dependence of successful airway management in neonatal simulators on the device type and providers' backgrounds. Ninety-one healthcare providers performed four attempts at airway management using a laryngeal mask and i-gel in two types of neonatal manikins...

Supraglottic airway (SGA) is an alternative to endotracheal intubation, however endotracheal intubation is often essential. One method to convert from an SGA to an endotracheal tube (ETT) is utilizing the SGA as a conduit for fiberoptic-guided advancement of an Aintree catheter (airway exchange catheter), and exchange of the SGA for an ETT. In this prospective randomized study, we compared two SGA devices in facilitating this exchange. Subjects were randomized to receive either the i-gel® or LMA® Supreme™ SGA...

INTRODUCTION: Laryngeal mask airway-blockbuster (LMA-BT) is a relatively new supraglottic airway device (SGAD). In this study, we compared LMA-BT with I-Gel LMA for efficacy of blind tracheal intubation. MATERIAL AND METHODS: We conducted a single-blind prospective study after ethical approval. One hundred American Society of Anesthesiology (ASA) Grade I-III (age 18-60 years) patients scheduled for elective surgery under general anaesthesia with endotracheal intubation were included and randomly divided into 2 groups...

INTRODUCTION: Current guidelines for neonatal resuscitation suggest the use of a laryngeal mask when ventilation with both facemask and endotracheal tube has failed in newborns weighing >2000 g or delivered ≥ 34 weeks of gestation age. Paediatric I-gel® is one of the latest supraglottic airway management devices suitable for children and newborns. I-gel® use was effective in guaranteeing adequate ventilation in patients with anatomic abnormalities in case of respiratory impairment or during surgical procedures after the induction of anaesthesia...

PURPOSE: Remimazolam is a recently developed ultra-short-acting benzodiazepine used for anesthesia induction and maintenance. Nevertheless, the effective bolus dose of remimazolam for i-gel® (Intersurgical Ltd., Wokingham, Berkshire, UK) insertion without the use of neuromuscular blocking agents (NMBAs) has not been well established. METHODS: This study included 25 adult patients scheduled for surgery under general anesthesia who were eligible for i-gel use...

INTRODUCTION: Accidental extubation during prone position can be a life-threatening emergency requiring rapid establishment of the airway. However, there is limited evidence of the best airway rescue method for this potentially catastrophic emergency. The aim of this study was to determine the most effective method to recover the airway in case of accidental extubation during prone positioning by comparing three techniques (supraglottic airway, video laryngoscopy, and fiber-optic bronchoscopy) in a simulated environment...

OBJECTIVE: Unlike randomized controlled trials, practical real-world studies can offer important information about implementation of prehospital interventions, particularly in community settings where there may be reluctance to adopt new practices. We present the results of a natural experiment that was driven by mandated COVID-19 pandemic-driven shift from endotracheal intubation (ETI) to the i-gel® supraglottic airway (SGA) as a primary advanced airway management device in the prehospital setting to reduce emergency medical services (EMS) personnel exposure to potentially infectious secretions...

PURPOSE: Anesthesiologists can use supraglottic airway devices as a rescue technique for failed intubation even in patients with an increased risk of gastric regurgitation. In this randomized study, we aimed to evaluate the effects of cricoid pressure and paratracheal pressure on placement of the i-gel® (Intersurgical Ltd., Wokingham, Berkshire, UK). METHODS: After induction of anesthesia in 76 adult patients, we inserted the i-gel under paratracheal or cricoid pressure, and assessed the success rate of i-gel insertion, resistance during insertion, time required for insertion, accuracy of the insertion location, tidal volumes, and peak inspiratory pressure with or without each maneuver after i-gel insertion...

BACKGROUND: Annulus fibrosis (AF) defects have been identified as the primary cause of disc herniation relapse and subsequent disc degeneration following discectomy. Stem cell-based tissue engineering offers a promising approach for structural repair. Menstrual blood-derived mesenchymal stem cells (MenSCs), a type of adult stem cell, have gained attention as an appealing source for clinical applications due to their potential for structure regeneration, with ease of acquisition and regardless of ethical issues...

This study is the first to report 50% and 95% effect-site concentrations (EC50 and EC95 , respectively) of the new short-acting benzodiazepine, remimazolam, for the successful insertion of i-gels with co-administration of fentanyl. Thirty patients (38 ± 5 years old, male/female = 4/26) were randomly assigned into five groups to receive one of five different remimazolam doses (0.1, 0.15, 0.2, 0.25, and 0.3 mg/kg bolus followed by infusion of 1, 1.5, 2, 2.5, and 3 mg/kg/h, respectively, for 10 min), which were designed to maintain a constant effect-site concentration of remimazolam at the time of i-gel insertion...

Wound management practices have made significant advancements, yet the search for improved antiseptics persists. In our pursuit of solutions that not only prevent infections but also address broader aspects of wound care, we investigated the impact of integrating trimethyl chitosan (TMC) into a widely used poly(vinylpyrrolidone)-iodine gel (PVP-I gel). Our study assessed the antimicrobial efficacy of the PVP gel with TMC against Escherichia coli , Staphylococcus aureus , multidrug-resistant S. aureus MRSA, and Candida albicans ...

(1) Background: The physiological and pharmacological variations between men and women are known to influence drug efficacy. The objective of this study was to determine the 50% and 95% effective doses (ED50 and ED95 ) of remimazolam required for i-gel supraglottic airway (ISA) insertion under remifentanil infusion without neuromuscular blocking agents (NMBAs) in both males and females. (2) Methods: Patients aged 19-65 years, scheduled for general anesthesia using ISA, were enrolled in this study. Patients were divided into two groups based on their sex...

Negative pressure pulmonary edema (NPPE) is a rare complication that occurs mainly after tracheal extubation. We report a case of postoperative NPPE associated with the use of the i-gel. A 28-year-old woman was scheduled for an emergency right axillary sentinel lymph node excision. During emergence, the patient experienced a sudden onset of airway obstruction, and spontaneous ventilation through the i-gel was impossible. Pink and frothy secretions were noted in the i-gel and the patient's oral cavity. Positive airway pressure with 100% oxygen was applied using a facemask, and the patient was subsequently treated with high-flow oxygen therapy...

BACKGROUND AND AIMS: Different techniques of i-gel insertion have been described with variable success rates. This study aimed to assess the incidence of malposition of i-gel in children with 90° rotation, 180° rotation, jaw thrust-assisted and standard insertion techniques. METHODS: The study included 132 children undergoing elective surgery under general anaesthesia without neuromuscular blockade after approval from the Institutional Ethics Committee...

OBJECTIVE: The Los Angeles County Fire Department Lifeguard Division responds to water rescues and medical and dive emergencies across 72 miles of Southern California coastline and Catalina Island. Limited advanced life support resources make cardiac arrest resuscitations logistically challenging during transport to shore or the hyperbaric chamber. This proof-of-concept study looked to determine if an i-Gel (Intersurgical Complete Respiratory Systems, Wokingham, Berkshire, UK) supraglottic airway device would either become dislodged or compromise ventilations during prolonged resuscitation at high speeds over open water with an ongoing automatic chest compression device (ACCD)...

Composite collagen gels with hyaluronic acid are developed tissue-engineered structures for filling and regeneration of defects in various organs and tissues. For the first time, phytic acid was used to increase the stability and improve the mechanical properties of collagen gels with hyaluronic acid. Phytic acid is a promising cross-linker for collagen hydrogels and is a plant-derived antioxidant found in rich sources of beans, grains, and oilseeds. Phytic acid has several benefits due to its antioxidant, anticancer, and antitumor properties...

The optimal timing of I-Gel removal in children with mild respiratory symptoms remains controversial. Consequently, we tried to assess the impact of early versus late I-Gel removal on the incidence of perioperative respiratory adverse events among children aged one to five years undergoing ambulatory surgery under general anaesthesia with I-Gel airway ventilation. The anaesthesia protocol was the same for all patients. Children were divided into two groups according to the approach of I-Gel removal (early versus late)...

Biota samples are used to monitor chemical stressors and their impact on the ecosystem and to describe dietary chemical exposure. These complex matrices require an extraction step followed by clean-up to avoid damaging sensitive analytical instruments based on chromatography coupled to mass spectrometry. While interest for non-targeted analysis (NTA) is increasing, there is no versatile or generic sample preparation for a wide range of contaminants suitable for a diversity of biotic matrices. Among the contaminants' variety, persistent contaminants are mostly hydrophobic (mid- to non-polar) and bio-magnify through the lipidic fraction...
