Abstract:Background
To preliminary evaluate the application of SaCoVLM™ video laryngeal mask airway in airway management of general anesthesia.
Methods
We 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… Show more
“…The rst-attempt success rate of SaCoVLM insertion was 92.7% (95%CI = 1.03-1.13)in children ,which con rms that the success rate of devices insertion is lower than that in adults with normal airway [13][14], This may be due to the anatomical differences in children with microtia,which may existing a narrow laryngeal space .After manual adjustment 15 and reinsertion, the nal success rate of device insertion can reach 100%.…”
Backgrounds: To preliminary evaluate the application of novel SaCoVLM video laryngeal mask -guided intubation for anesthetized children.
Methods:.124 children with microtia (ages 5-15years,) who required general intubation anaesthesia, were enrolled in the study. After induction of general anesthesia,guided tracheal intubation under direct vision of the SaCoVLM was performed. Our primary outcome was first-pass success rate of guided tracheal tube placement. Secondary outcome included glottic visualization grades, the first-attempt success rate of LMA placement, the time for LMA placement and time to endotracheal intubation as well as the time for LMA removal after successful intubation, the fiberoptic grade of laryngeal view, the baseline and postinduction hemodynamic parameters were also recorded,and the incidence 24h complications after operation.
Results: The first-pass success rate of guided tracheal tube placement was 91.1%（95%CI=1.04-1.14）, the status of glottic visualization was classified:grade 1 in 27cases,grade 2 in 36 cases,grade 3 in 41 cases and grade 4 in 20 cases. the first success rate of LMA placement was 92.7%（95%CI=1.03-1.13）,the time for LMA insertion was 15.7(±9.1)s,intubation time was 30.9(±17.6)s and withdrawl time was 24.9(±9.3)s, the MAP value was higher after intubation than before intubation(p<0.05),The incidence of postoperative sore throat at 2h was 29%, and 16.1% at 24h,without dysphagia and hypoxia.
Conclusion:The SaCoVLM video laryngeal mask-guided intubation is feasible in children, with a high success rate ,could be a new promising device to guide intubation in airway management.

“…[28][29][30][31] The SaCoVLM has shown advantages in clinical applications since its creation in 2018. 32 The SaCoVLM is comparable in price with a common LMA and can easily be clinically promoted, allowing visualisation of the conditions around the glottis and thus achieving rapid and accurate insertion. Additionally, the operator can visualise the passage of the tracheal tube through the glottis during intubation.…”
IntroductionThe SaCoVLM is a new type of video intubating laryngeal mask airway (LMA), and it is the first LMA to realise continuous visual monitoring. There is a lack of studies on intubation using the SaCoVLM. The aim of this study is to compare the success rate of intubation with polyvinyl chloride (PVC) tubes and wire-reinforced (WR) tubes using the SaCoVLM.Methods and analysisThis prospective, single-centre, single-blind, parallel-arm, randomised controlled study will be conducted in a tertiary university hospital in China. We will include 104 patients undergoing elective laparoscopic surgery under general anaesthesia. Patients will be randomly assigned to the PVC tracheal tube group (n=52, PVC group) or the WR tracheal tube group (n=52, WR group). The primary outcome is the total success rate of intubation. The secondary outcomes are the first success rate of intubation, the time of tracheal intubation, the site of the first contact, the adjustment action for tracheal intubation, haemodynamic fluctuation during intubation and extubation, incidence of trauma as evidenced by blood, and the incidence rates of postoperative sore throat, hoarseness, and dysphagia.Ethics and disseminationThis study was approved by the Ethics Committee of the First Affiliated Hospital of Shandong First Medical University (YXLL-KY-2022 (008)). All participants will provide written informed consent. The results will be disseminated through peer-reviewed publications and at conferences or congresses.Trial registration numberNCT05338827.
Backgrounds
To preliminary evaluate the application of novel SaCoVLM video laryngeal mask -guided intubation for anesthetized children.
Methods
One hundred twenty-four children with microtia (ages 5-15 years,) who required general intubation anaesthesia, were enrolled in the study. After induction of general anesthesia,guided tracheal intubation under direct vision of the SaCoVLM was performed. Our primary outcome was first-pass success rate of guided tracheal tube placement. Secondary outcome included glottic visualization grades, the first-attempt success rate of LMA placement, the time for LMA placement and time to endotracheal intubation as well as the time for LMA removal after successful intubation, the fiberoptic grade of laryngeal view, the baseline and postinduction hemodynamic parameters were also recorded,and the incidence 24 h complications after operation.
Results
The first-pass success rate of guided tracheal tube placement was 91.1% (95%CI = 1.04–1.14), the status of glottic visualization was classified: grade 1 in 27cases, grade 2 in 36 cases, grade 3 in 41 cases and grade 4 in 20 cases. The first success rate of LMA placement was 92.7% (95%CI = 1.03–1.13), the time for LMA insertion was 15.7 (±9.1) s, intubation time was 30.9 (±17.6) s and withdrawl time was 24.9 (±9.3) s. The incidence of postoperative sore throat at 2 h was 29%, and 16.1% at 24 h, without dysphagia and hypoxia.
Conclusion
The SaCoVLM video laryngeal mask-guided intubation is feasible in children, with a high success rate, could be a new promising device to guide intubation in airway management.
