Abstract

Purpose: The role of load distributing band device (LDB, AutoPulse® Zoll Medical Corporation, Chelmsford, MA, USA) in out-of-hospital cardiac arrest is still a matter of debate, with few studies reaching conflicting results available in literature. We sought to assess whether the use of the LBD device could affect survival to hospital discharge in the different Utstein categories. Materials and methods: All consecutive patients enrolled in our provincial cardiac arrest registry (Pavia CARe) from January 2015 to December 2017 were included and pre-hospital data were computed as well as survival to hospital discharge. Results: Among 1401 resuscitation attempts, the LDB device was used in 235 (17%) patients. The LDB device was significantly more used for shockable cardiac arrest (42.6% vs 13.7%, p < 0.001). The rate of ROSC and of survival to hospital discharge in the LDB group compared to the manual group was 40% vs 17% (p < 0.001) and 10% vs 7% (p = 0.2), respectively. However, after correction for independent predictors of LDB use, LDB device was a strong independent predictor of survival to hospital discharge only for non-shockable witnessed OHCA [n = 624/1401, OR 11.9 (95% CI 1.5–95.2), p = 0.02]. In this categories of patients LDB group showed longer resuscitation time [49.3 min (IQR 37–71) vs 23.6 (IQR 15–35), p < 0.001] and a higher rate of conversion to a shockable rhythm (33/83 = 40% vs 29/541 = 5%, p < 0.001). Conclusion: Utstein categories-based analysis showed that the LDB device positively affect survival to hospital discharge for non-shockable witnessed cardiac arrests with a neutral effect for shockable rhythms.
