Impact of Suction-Assisted Laryngoscopy and Airway Decontamination Technique on Intubation Quality Metrics in a Helicopter Emergency Medical Service: An Educational Intervention.

OBJECTIVE: Suction-assisted laryngoscopy and airway decontamination (SALAD) was created to assist with the decontamination of a massively soiled airway. This study aims to investigate the usefulness of SALAD training to prehospital emergency providers to improve their ability to intubate a massively contaminated airway. METHODS: This was a prospective study conducted as a before and after teaching intervention. Participants were made up of prehospital providers who were present at regularly scheduled training sessions and were asked to intubate a high-fidelity mannequin simulating large-volume emesis before and after SALAD instruction. They were subsequently tested on 3-month skill retention. Twenty subjects participated in all stages of the study and were included in the analysis. RESULTS: The median time to successful intubation for all study participants before instruction was 60.5 seconds (interquartile range [IQR] = 44.0-84.0); post-training was 43.0 seconds (IQR = 38.0-57.5); and at the 3-month follow-up, it was 29.5 seconds (IQR = 24.5-39.0). The greatest improvement was seen on subgroup analysis of the slowest 50th percentile where the median time before instruction was 84.0 seconds (IQR = 68.0-96.0); post-instruction was 41.5 seconds (IQR = 36.0-65.0); and at the 3-month follow-up, it was 29.5 seconds (IQR = 25.0-39.0). CONCLUSION: The implementation of the SALAD technique through a structured educational intervention improved time to intubation and the total number of attempts.

Effect of Suction Assisted Laryngoscopy Airway Decontamination (SALAD) Training on Intubation Quality Metrics.

INTRODUCTION: VCU Health Critical Care Transport Network paramedics and nurses staff three rotary-wing aircraft and one ground ambulance that provide scene response and interfacility transports throughout Virginia. Prehospital rapid sequence induction and intubation are among the highest risk procedures employed by these providers, particularly when the airway is massively contaminated with blood or vomit. A quality assurance review of attempted prehospital intubations determined issues with suction to be a key factor in those requiring more than one attempt. A targeted training session introducing Suction Assisted Laryngoscopy and Airway Decontamination (SALAD) was implemented and quality improvement data collected. METHODS: SALAD was introduced during scheduled quarterly training. In attendance were 15 nurses and 10 paramedics for a total of 25 participants. With no prior notice, training or cognitive priming each participant attempted intubation using videolaryngoscopy on a custom high fidelity training mannequin designed to emit 650 ml per minute of simulated vomit into the airway. Following their first attempt, participants were instructed on SALAD technique by an EMS-fellowship trained emergency physician. Participants then had another opportunity to intubate the mannequin using SALAD technique. Data was collected on number of attempts and time to successful intubation before and after training. RESULTS: Mean time to successful intubation improved from 68.28 seconds to 49.76 seconds (95% confidence interval [CI], -34.976 to -2.064; P = 0.0282). There was a trend toward improvement in mean number of intubation attempts overall from 1.12 per participant to 1.0 (CI, -0.0135 to 0.2535; P = <0.0001). Subgroup analysis, however, found there to be significant improvement for participants whose first attempt time was greater than 91 seconds, from a mean of 127.40 seconds to 53.80 seconds (CI, -116.674 to -30.526; P = 0.043) and 1.6 attempts per participant to 1.0 (CI, -1.165 to -0.0349; P = 0.0400) post intervention. CONCLUSION: In a controlled environment, SALAD training improves both first pass success and total time to successful intubation. The greatest improvement was observed in the group with the most difficulty and longest time to intubation prior to the targeted educational intervention. This indicates that the introduction of an effective, standardized suction technique for massively contaminated airways can significantly improve quality metrics for intubation by prehospital providers. Further research is needed to determine skill retention and generalizability to an uncontrolled environment.

Intubation Success after Introduction of a Quality Assurance Program Using Video Laryngoscopy.

OBJECTIVE: The deployment of video laryngoscopy devices that include recording capability presents a new and unique opportunity for medical directors to review prehospital patient encounters. We sought to evaluate the effect of introducing a video laryngoscope and video quality assurance program to an air medical program on measures of intubation success including overall success, first-pass success, success within 2 attempts, and the total number of attempts. METHODS: This was a retrospective review of data collected on intubations by nurses and paramedics of the Virginia State Police Med-Flight 1 air medical program. RESULTS: After introduction of the video laryngoscope and quality assurance program, the overall intubation success improved to 100% but did not reach statistical significance (95% confidence interval [CI], -4.40 to 12.57; P = .25). First-pass success improved from 76.19% to 92.86% (CI, 1.14-33.14; P = .02), whereas the average attempts declined from 1.31 to 1.09 per patient encounter (CI, -.41 to -.03; P = .02). Success within 2 attempts was 92.86% before the intervention and 98.21% after (CI, 4.25-17.82; P = .19). CONCLUSION: Video laryngoscopy and a robust means for medical director oversight are important components of a high-performance airway management program and demonstrably improve intubation first-pass success.
