Background:Rapid sequence intubation (RSI) has been an established practice, but is not without risks to patient. In different situations, a modification of the standard RSI technique may be more appropriate. The definition of a modified rapid sequence intubation (MRSI) is not well-documented. The purpose of this survey was to determine the working definition of MRSI as well as the modality of its use.Materials and Methods:This descriptive study consisted of a survey of pediatric anesthesiologists and included basic questions related to the anesthesiologist's experience, practice setting and use of MRSI. Responses were compiled and analyzed to identify the working definition, technique, perceived indications/complications as well as hands-on performance of tracheal intubation during use of MRSI in children.Results:The mean ± SD years in practice of the 228 respondents were 14.9 ± 8.16 years, with pediatric patients comprising 77 ± 33% of their practice. 76.8% completed a fellowship in pediatric anesthesia. 60% of the respondents’ practice setting was at a Children's Hospital. Different respondents agreed with different techniques of MRSI with the majority (65%) defining a MRSI as equivalent to a RSI, but with mask ventilation. The major indication of use of a MRSI was a concern about apnea time tolerance with traditional RSI (74%).Conclusion:Technique of a MRSI varies among pediatric care providers.
