Background: Video laryngoscope (VL) is a tool that has increased the intubation success rate, but it is expensive and difficult to carry outside the hospital. Ramathibodi mobile Video laryngoscope (RAMA-mVL) thus was invented for having effectiveness equivalent to the current device and lower price.
Objective: To determine the effectiveness of intubation by comparing between RAMA-mVL and McGrath®.
Methods: This study conducted a randomized, single-blinded study in manikin comparing RAMA-mVL and McGrath®. Medical personnel with intubation experiences were included and will be trained in 2 devices before performing the procedures. Intubation success rate, time to intubation, satisfaction, and the cost between both VLs were compared.
Results: A total of 208 persons were enrolled in the research, 104 in each group. The first pass succession rate for intubation by using both VLs is 100%. Time to intubation using RAMA-mVL was significantly less than that of McGrath® (mean [SD], 9.12 [4.28] and 11.19 [5.04] seconds, respectively; P = .002). The 5-point Likert scale in satisfaction rate on the easy to build in RAMA-mVL and McGrath® were mean (SD) of 4.88 (0.32) and 4.23 (0.96) points respectively (95% CI, 0.46 - 0.85; P < .001). Additionally, the cost of RAMA-mVL was cheaper than McGrath®.
Conclusions: The first pass intubation success rate in a manikin of RAMA-mVL is equivalent to McGrath®. The cost of RAMA-mVL is cheaper.
