AbstractEmergency airway management outside the operating room (OR) is a higher risk procedure as compared to the OR setting. Inappropriate airway management leading to complications, including pulmonary aspiration, dental trauma, esophageal intubation, prolonged recovery, unplanned intensive care unit admission and death. The emergency difficult airway management team of Siriraj hospital has been established since 2018 under the name of Code-D delta. The aim of this study is to determine the rate of Code D-delta activation, the performance of the code, the complications and outcome of the patients. This is a single-centered, observational, and retrospective study included all adult patient who was emergency intubated outside the OR between July and November 2020. The criteria for code D-delta activation included failed intubation for more than 2 attempts and suspected difficult intubation. The collected data were categorized into Code D-delta activation and non-activation group. The primary outcome was a frequency of Code D-delta activation. The demographic data, ward and indication of activation, intubation process, the complications of intubation were also collected and analyzed. During the study period, 247 patients with 307 intubations were included. The incidence of code D-delta activation was 8.14%. Regarding indication of activation, failed intubation more than 2 attempts was 40%, while suspected difficult intubation was 92%. Respiratory failure was the highest main diagnosis at 36%. The highest rate of activation was from medicine ward (60%), followed by surgery ward (16%) and emergency department (16%). Regarding the code responses and intubation performance, 7 and 10 minutes were the median time from call to scene in- and out- of official hours. The success rate of intubation at scene by code D-delta team was 85%. The airway and other complications were comparable between groups. This is the first study about emergency difficult airway management team in university hospital of Thailand. This study showed the rate of Code-D delta activation, the emergency airway management code, was 8.14% with the success rate of 85% at scene. Emergency airway management outside the operating room is particularly challenging. Airway assessment, planning, decision making of the team relevant to the patients outcomes.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
