Association of Respiratory Parameters at Venovenous Extracorporeal Membrane Oxygenation Liberation With Duration of Mechanical Ventilation and ICU Length of Stay: A Prospective Cohort Study.

ABSTRACT: Although the criteria for initiation of venovenous extracorporeal membrane oxygenation (VV ECMO) are well defined, the criteria and timing for VV ECMO decannulation are less certain. The aim of this study was to describe the ventilation and physiologic factors at the time of VV ECMO decannulation and to determine if these factors have association with mechanical ventilation or ICU length of stay after ECMO decannulation.

Design

Multicenter, prospective cohort study.

Setting

Eleven ICUs in Australia.

Patients

Adult patients treated with VV ECMO from March 19, 2019, to September 20, 2020.

Interventions

Liberation from VV ECMO.

Results

Of 87 patients receiving VV ECMO, the median age was 49 years (interquartile range, 37-59 yr), 61 of 87 (70%) were male, and 52/87 (60%) had a diagnosis of acute respiratory distress syndrome. There were 24 of 87 patients (28%) who died prior to day 90. No patient required a second run of VV ECMO. In a multivariate models, a higher partial pressure of arterial carbon dioxide (p < 0.01) and respiratory rate at the time of decannulation (p = 0.01) were predictive of a longer duration of mechanical ventilation and ICU length of stay postdecannulation in survivors. Higher positive end-expiratory pressure at ECMO decannulation was associated with shorter duration of ICU length of stay post-ECMO decannulation in survivors (p = 0.01).

Conclusions

A higher partial pressure of arterial carbon dioxide and higher respiratory rate at ECMO decannulation were associated with increased duration of mechanical ventilation and increased duration of ICU stay postdecannulation, and increased positive end-expiratory pressure at decannulation was associated with decreased duration of ICU stay postdecannulation. Future research should further investigate these associations to establish the optimal ventilator settings and timing of liberation from VV ECMO.

Project description:Patients on extracorporeal support for severe acute respiratory distress syndrome may require a prolonged period of deep sedation. In these patients, volatile sedation may represent a valid alternative to IV drugs. The aim of our study was to describe the feasibility of volatile sedation in a large cohort of acute respiratory distress syndrome patients undergoing venovenous extracorporeal membrane oxygenation and ultraprotective ventilation.DesignRetrospective monocentric study.SettingAdult ICU, ASST Monza, Italy.PatientsAdult patients who underwent volatile sedation with isoflurane during venovenous extracorporeal membrane oxygenation between 2009 and 2019.InterventionsIsoflurane was delivered via the AnaConDa system. The sedation level, hemodynamics, and laboratory tests were compared between the volatile sedation phase and the IV sedation phases before and after the isoflurane sedation period.Measurements and main resultsAbout 74 patients (50 yr [43-56 yr]) were included. Median duration of venovenous extracorporeal membrane oxygenation support was 22 days (14-51 d). Volatile sedation started on day 3 (2-6) of extracorporeal membrane oxygenation support, and its median duration was 7 days (4-13 d), ranging from 1 to 38 days. A total of 970 venovenous extracorporeal membrane oxygenation days were analyzed. During the volatile phase, the sedation level was slightly deeper (bispectral index 39 ± 6) compared with the IV phase before and after isoflurane (42 ± 8 and 43 ± 9, respectively, p < 0.001). Requirements of fentanyl and remifentanyl were reduced during the volatile phase. Minor differences in hemodynamics were observed during volatile sedation: mean arterial pressure was lower (75 ± 13 vs 79 ± 14 and 80 ± 15; p < 0.001), whereas cardiac output was higher (8.5 ± 1.9 vs 7.9 ± 1.8 and 8.0 ± 1.8; p = 0.003). Aspartate aminotransferase levels were lower during the volatile sedation phases (p < 0.001), whereas alanine aminotransferase, triglycerides, and creatine phosphokinase were more altered during the IV sedation phase before isoflurane (p < 0.001).ConclusionsVolatile sedation represents an alternative to IV agents to achieve long-term deep sedation in critically ill patients on extracorporeal membrane oxygenation undergoing ultraprotective ventilation.
