Abstract

Background & Objectives: Totaltrack is a new video laryngoscope which is built in a laryngeal mask allowing the anesthesiologist the ventilation during the whole process of intubation. Materials & Methods: This case series includes 43 patients undergoing elective surgery under general anesthesia. Standard monitorization was performed. All patients were preoxygenated with 80% oxygen for 3 minutes. General anesthesia was induced with: propofol 2mg/Kg, Fentanyl 2mcg/Kg, dexamethasone 0.1mg/Kg. Rocuronium was used as neuromuscular blocker at a dose of 0.6mg/Kg not util the vocal cords were seen with the videolaringoscope. Once the laryngeal mask was correctly placed, leak pressure was measured by measuring the inspiratory pressure at which and audible noise was noticeable. (1) All 43 patients were intubated by experienced anesthesiologists with a Totaltrack® device. All data were analyzed using PSPP 0.8.5 GNU statistical software. Results: All 43 patients were succesfully intubated and extubated without incidences. There was no lip, dental or laryngeal trauma. Mean leak pressure was 39 cmH2O. (SD=3) (see figure 1). Mean time for intubation was 311,2 (SD=77,46) (see figure 2). The relationship between minimum SPO2 and the time of insertion was not significant. And minimum desaturation observed in all patients was 95% in only one of the cases (see figure 3). All this data may probably be due to the possibility of being ventilating during all the process of intubation. Knowing all the details about the devices we use is important. Leak pressure is important data in order to ventilation at high pressure in situations we may need to do it. In comparison with other devices, bibliography refers to a mean 25.27 cmH2O leak pressure of the igel, and 29.6 cmH2O for the LMA-proseal (2). A mean time for intubation procedure of 311 can be too long for the normal intubation process, but we have to take into account the absence of desaturation and the security of the process.Conclusion: · Totaltrack® is a new device that allows ventilation during the whole process of intubation. It has a supraglotic device included in it for this task. Supraglotic Totaltrack® leak pressure in our study is mean 39 H2Ocm (SD=3) No desaturation was observed in none of the patients of this series, with a mean time of insertion and intubation of 311 seconds.
