“…The intubation success rate of 91% was comparable with a previous study from Kleine‐Brueggeney in the i‐gel and single Intubation laryngeal mask (sILMA™). A recent study by Gawlowski et al showed a successful blind intubation rate through the i‐gel of 95.7%. Because of the “hanging up” of the endotracheal tube, as previous described, two patients in the AuraGain™ and one patient in the i‐gel group needed a second intubation …”

“…Many studies on optimal intubating methods for patients in such cases mainly focused on the demonstration of superiority by comparing novel devices with conventional laryngoscopes [ 28 ]. However, our study aimed to provide specific values on why the use of a conventional laryngoscope is difficult.…”

Cervical collar makes difficult airway: a simulation study using the LEMON criteria

ObjectiveEndotracheal intubation is extremely difficult to perform in patients wearing a cervical collar for a head and neck injury. Therefore, we analyzed actual measurements using the look externally, evaluate 3-3-2, Mallampati score, obstruction, and neck mobility (LEMON) criteria before and after cervical collar application to investigate the causes of a difficult airway.MethodsThis simulation study was performed in 76 healthy volunteers. We measured the mouth opening, modified Mallampati classification, and neck extension before and after cervical collar application.ResultsThe mean inter-incisor distance significantly decreased from 4.3 to 2.6 cm (P<0.001). Fifty-seven participants classified as I and II were newly classified as III and IV according to the modified Mallampati classification after cervical collar application (16% to 91%). The angles of neck extension significantly decreased from 44° to 22° after cervical collar application (P<0.001). Before cervical collar application, our simulations predicted that 14 of 76 participants (18%) would have a difficult airway, whereas after cervical collar application, 76 of 76 (100%) were predicted to have a difficult airway.ConclusionAll values for the LEMON criteria (mouth opening, modified Mallampati classification, and neck extension) worsened significantly after cervical collar application. Additionally, a difficult airway was predicted in all participants after cervical collar application.

“…It is worth emphasising, that the degree of mouth opening is directly correlated with the effectiveness of endotracheal intubation performed using the direct laryngoscopy. However, as indicated by the number of studies conducted by Madziala et al [10,11] and Gawlowski et al [6,12], the efficacy of endotracheal intubation using a videolaryngoscope in the case of cervical spine stabilisation is as high as in normal airways.…”

INTRODUCTION: Securing the stability of the cervical spine is one of the basic procedures performed by medical personnel in trauma patients. Unfortunately, standard cervical collars limit the effectiveness of some procedures, including endotracheal intubation, as well as affect the pain sensations of the injured person. The aim of the study was to compare the influence of two different types of cervical collars on the technical conditions of endotracheal intubation and the patient's sense of comfort. METHOD: The study was designed as a randomised, cross-over research and included 32 healthy paramedics, who had a cervical collar installed for 20 minutes in a randomised way. During the examination, the patient's comfort and pain resulting from the pressure on mastoid processes were evaluated. RESULTS: Prior to the study, the mouth opening in the examined group was 51 ± 12 mm. After the setup of the Patriot collar, the mouth opening amounted to 37 ± 10 mm, while in the NECKLITE collar group amounted to 49 ± 13 mm (p < 0.001). The use of a cervical collar reduced the degree of mouth opening by 27% when using a standard cervical collar, and less than 4% when using a NECKLITE collar. The pressure on the mastoid processes assessed on a 10-point scale varied between the cervical collars and amounted to 7 ± 2 points for Patriot and 1 ± 1 points for NECKLITE collar (p < 0.001). The pain sensations associated with the cervical collar were also varied and amounted to 6 ± 3 points for Patriot collar vs. 1 ± 1 points for NECKLITE collar (p < 0.001). Ninety-seven per cent of study participants declared, that they preferred the NECKLITE collar comparing to the Patriot cervical collar. CONCLUSIONS: A standard cervical collar causes an increase in pain due to the pressure on the mastoid processes and a sense of discomfort for the patient. The NECKLITE collar thanks to the possibility of better fit to the patient's neck, does not cause any pain, and using this collar it is possible to perform endotracheal intubation without the need to unfasten it.
