PurposeEndotracheal intubation is a lifesaving procedure for airway management but is more complex when performed in patients lying on the ground and requiring cervical spine immobilization. This study aims to compare the optimal technique between prone and kneeling positions in increasing intubation success rate on these prehospital trauma patients.Patients and MethodsThis study was an experimental study on a mannequin. Paramedic students performed intubation on the supine mannequin, which was applied with a rigid cervical collar and manual in-line stabilization. The participants were randomly assigned to intubate in a prone or kneeling position as the first method, then perform another method seven days later. Study outcomes include the percentage of successful intubation, time to perform intubation successfully, and Cormack and Lehane’s classification of laryngeal view.ResultsThirty-nine participants were enrolled in this study; 22 were male (56.41%). The mean age, weight, and height were 23.15 ± 4.75 years, 67.38 ± 17.39 kg, and 167.36 ± 8.70 cm., respectively. The percentage of successful intubation in prone (37 [94.90%]) was higher than kneeling position (35 [89.74%]), but there was no statistically significant (p-value = 0.675). Time to intubation successfully, the number of attempts, and Cormack & Lehane's laryngeal view classification were not significantly different between prone and kneeling groups (p-value = 0.808, 0.814, and 0.948, respectively).ConclusionIntubation with the prone or kneeling position on a mannequin, lying on the ground with cervical spine immobilization, has no statistical difference. Both intubation approaches appear to be effective in successful and rapid intubation, proper glottic visualization and low attempts.
