Abstract
BackgroundTo preliminary evaluate the application of SaCoVLM™ video laryngeal mask airway in airway management of general anesthesia.MethodsWe recruited 100 adult patients (ages 18–78 years, male 19, female 81, weight 48–90 kg) with normal predicted airway (Mallampati I ~ II, unrestricted mouth opening, normal head and neck mobility) and ASA I-II who required general anaesthesia. The SaCoVLM™ was inserted after anesthesia induction and connected with the anesthesia machine for ventilation. Our primary outcome was glottic visualization grades. Secondary outcomes included seal pressure, success rate of insertion, intraoperative findings (gastric reflux and contraposition), gastric drainage and 24-h complications after operation.ResultsThe laryngeal inlet was exposed in all the patients and shown on the video after SaCoVLM™ insertion. The status of glottic visualization was classified: grade 1 in 55 cases, grade 2 in 23 cases, grade 3 in 14 cases and grade 4 in 8 cases. The first-time success rate of SaCoVLM™ insertion was 95% (95% CI = 0.887 to 0.984), and the total success rate was 96% (95% CI = 0.901 to 0.989). The sealing pressure of SaCoVLM™ was 34.1 ± 6.2 cmH2O and the gastric drainage were smooth. Only a small number of patients developed mild complications after SaCoVLM™ was removed (such as blood stains on SaCoVLM™ and sore throat).ConclusionsThe SaCoVLM™ can visualize partial or whole laryngeal inlets during the surgery, with a high success rate, a high sealing pressure and smooth gastroesophageal drainage. SaCoVLM™ could be a promise new effective supraglottic device to airway management during general anesthesia.Trial registrationChiCTR,ChiCTR2000028802.Registered 4 January 2020.
Highlights
To preliminary evaluate the application of SaCoVLMTM video laryngeal mask airway in airway manage‐ ment of general anesthesia
Using new technology combining camera and Laryngeal mask, it can visualize the conditions around the glottis, achieving rapid and accurate insertion
The purpose of this study was to observe the visibility of SaCoVLMTM video laryngeal mask in clinical use and to preliminarily evaluate its application in airway management under general anesthesia
Summary
To preliminary evaluate the application of SaCoVLMTM video laryngeal mask airway in airway manage‐ ment of general anesthesia. Since the introduction of laryngeal mask in the late 1980s, the “blind” insertion technique described by Dr Brain has been widely used in clinical practice [1]. Previous studies found that approximately 40 to 60% of the laryngeal masks inserted blindly did not achieve ideal alignment with bronchofiberscope, and some even require re-alignment to improve ventilation [2, 3]. Using new technology combining camera and Laryngeal mask, it can visualize the conditions around the glottis, achieving rapid and accurate insertion. The purpose of this study was to observe the visibility of SaCoVLMTM video laryngeal mask in clinical use and to preliminarily evaluate its application in airway management under general anesthesia
