RESUMEN

OBJECTIVE: Our objective was to determine if implementing a standard lights and sirens (L&S) protocol would reduce their use and if this had any effect on patient disposition. METHODS: In a prospective cohort study, we trained emergency medical services (EMS) personnel from 4 towns in an L&S protocol and enrolled control personnel from 4 addition towns that were not using the protocol. We compare the use of L&S between them over a 6-month period. Our protocol restricted the usage of L&S to patients who had maladies requiring expedited transport. Emergency medical services personnel from the control towns had no such restrictions and were not aware that we were tracking their usage of L&S. We also considered if patient disposition was affected by the judicious usage of L&S. RESULTS: Prehospital EMS personnel who were trained in an L&S protocol were 5.6 times less likely to use L&S when compared with those not trained. Of the 808 patients transported by both types of workers, no difference in patient disposition was observed. CONCLUSIONS: Our protocol significantly reduced the use of L&S. Judicious use of L&S has significant implications for transport safety. By allowing for selective transport with L&S usage, we observed no impact in patient disposition.

RESUMEN

BACKGROUND: Several studies have been published in the literature about intubation methods, but little is available on intubation equipment used in this setting. This is the first prehospital comparison of disposable plastic vs disposable stainless steel laryngoscope blades used by paramedics. STUDY OBJECTIVE: The objective of this study was to compare prehospital intubation success rates on first attempt and overall number of attempts to obtain intubations using disposable plastic laryngoscopes blades vs disposable stainless steel laryngoscope blades. METHODS: A retrospective prehospital cohort study was conducted during two 3-year periods. Two-way contingency table and χ(2) test were conducted to determine if there was a difference between the 2 types of blades. A proportional odds model with calculated 95% confidence interval (CI) and odd ratios were then calculated. RESULTS: A total of 2472 paramedic intubations were recorded over the 6-year period. The stainless steel single-use blades had a first attempt success rate of 88.9% vs 78.5% with plastic blades (P = .01; odds ratio, 1.94; 95% CI, 1.17-3.41). The stainless steel single-use laryngoscope blade had a lower number of attempts to successful intubation than the plastic blade (88.8% vs 74.3%, respectively) (P < .01; odds ratio, 1.64; 95% CI, 1.34-2.00). CONCLUSIONS: In the prehospital setting, stainless steel disposable blades were superior to plastic disposable blades in first attempt and overall number of attempts to intubation. Until further research is done, we recommend use of stainless steel blades for intubations in the prehospital setting by paramedics.
