4.1. Significance of the Study Results
4.2. Comparison with Other Published Studies on This Topic-Similarities and Differences
4.3. Limitations of the Study
- This is the first study that compares two types of videolaryngoscopes, channeled and non-channeled, in relation to the effectiveness and possible complications of tracheal intubation in specific patient positioning in both the sitting and prone positions.
- New techniques and devices for airway management should be tested for possible application in very difficult airway scenarios (e.g., in entrapped patients or for intubation in patients requiring prone position such as for spinal neurosurgery procedures). This study provides answers on the efficacy of the evaluated videolaryngoscopes in such situations.
- Although main limitation of this study is that it was a manikin study, the human study can be performed as a follow up of this study, taking into consideration the important results of this work.
