Association between inflammation in acute phase and early onset pneumonia in patients with out-of-hospital cardiac arrest treated with extracorporeal cardiopulmonary resuscitation.

ABSTRACT:

Background

Early onset pneumonia (EOP) in patients with cardiac arrest treated with targeted temperature management is a recently debated issue. We assessed the association between C-reactive protein (CRP) levels and development of EOP in patients treated with extracorporeal cardiopulmonary resuscitation (ECPR).

Methods and results

We reviewed the data of all patients admitted to our hospital after out-of-hospital cardiac arrest treated with ECPR between April 2006 and April 2019 who survived for at least 48 h. We collected demographic data, cardiac arrest characteristics, prophylactic antibiotic use, and neurologic outcomes. Diagnosis of EOP was made based on clinical, radiological, and microbiological criteria. The primary endpoint was the association between the incidence of EOP and CRP levels from day 1 to day 4. A total of 55 patients were included, of which 20 developed EOP. CRP levels on days 3 and 4 were significantly elevated in patients who developed EOP (13.1 [11.8-21.1] mg/dL versus 11.6 [7.4-15.2] mg/dL, P = 0.005; and 19.0 [16.9-27.1] mg/dL versus 14.7 [7.4-21.2] mg/dL, P = 0.019, respectively). In the multivariable logistic regression model, the CRP level on day 3 was significantly associated with the development of EOP (odds ratio 1.22; 95% confidence interval 1.06-1.41; P = 0.001).

Conclusions

Increased inflammation in acute phase was associated with development of EOP in patients treated with ECPR.

Project description:BACKGROUND:The prognosis in refractory out-of-hospital cardiac arrest (OHCA) with ongoing cardiopulmonary resuscitation (CPR) at hospital arrival is often considered dismal. The use of extracorporeal cardiopulmonary resuscitation (eCPR) for perfusion enhancement during resuscitation has shown variable results. We aimed to investigate outcome in refractory OHCA patients managed conservatively without use of eCPR. METHODS:We included consecutive OHCA patients with refractory arrest or prehospital return of spontaneous circulation (ROSC) in the Copenhagen area in 2002-2011. RESULTS:A total of 3992 OHCA patients with resuscitation attempts were included; in 2599, treatment was terminated prehospital, and 1393 (35%) were brought to the hospital either with ROSC (n?=?1285, 92%) or with refractory OHCA (n?=?108, 8%). Of patients brought in with refractory OHCA, 56 (52%) achieved ROSC in the emergency department. There were no differences between patients with refractory OHCA or prehospital ROSC with regard to age, sex, comorbidities, or etiology of OHCA. Time to emergency medical services (EMS) arrival was similar, whereas time to ROSC (when ROSC was achieved) was longer in refractory OHCA patients (EMS, 6 (5-9] vs. 7 [5-10] min, p?=?0.8; ROSC, 15 [9-22] vs. 27 [20-41] min, p?<?0.001). Independent factors associated with transport with refractory OHCA instead of prehospital termination of therapy were OHCA in public (OR, 3.6 [95% CI, 2.2-5.8]; p?<?0.001), witnessed OHCA (OR, 3.7 [2.0-7.1]; p?<?0.001), shockable rhythm (OR, 3.0 [1.9-4.7]; p?<?0.001), younger age (OR, 1.2 [1.1-1.2]; p?<?0.001), and later calendar year (OR, 1.4 [1.2-1.6]; p?<?0.001). Thirty-day survival was 20% in patients with refractory OHCA compared with 42% in patients with prehospital ROSC (p?<?0.001). Four of 28 refractory OHCA patients with duration of resuscitation >?60 min achieved ROSC. No difference in favorable neurological outcome in patients surviving to discharge was found (prehospital ROSC 84% vs. refractory OHCA 86%; p?=?0.7). CONCLUSIONS:Survival after refractory OHCA with ongoing CPR at hospital arrival was significantly lower than among patients with prehospital ROSC. Despite a lower survival, the majority of survivors with both refractory OHCA and prehospital ROSC were discharged with a similar degree of favorable neurological outcome, indicating that continued efforts in spite of refractory OHCA are not in vain and may still lead to favorable outcome even without eCPR.

Project description:IntroductionExtracorporeal cardiopulmonary resuscitation (ECPR) is an emerging invasive rescue therapy for treatment of refractory out-of-hospital cardiac arrests (OHCA). We aim to describe the incidence of traumatic and hemorrhagic complications among patients undergoing ECPR for OHCA and examine the association between CPR duration and ECPR-related injuries or bleeding.MethodsWe examined prospectively collected data from the Extracorporeal Resuscitation Outcomes Database (EROD), which includes ECPR-treated OHCAs from participating hospitals (October 2014 to August 2019). The primary outcome was traumatic or hemorrhagic complications, defined any of the following: pneumothorax, pulmonary hemorrhage, major bleeding, cannula site bleeding, gastrointestinal bleeding, thoracotomy, cardiac tamponade, aortic dissection, or vascular injury during hospitalization. The primary exposure was the cardiac arrest to ECPR initiation interval (CA-ECPR interval), measured as the time from arrest to initiation of ECPR. Descriptive statistics were used to compare demographic, cardiac arrest, and ECPR characteristics among patients with and without CPR-related traumatic or bleeding complications. Multivariable logistic regression was used to examine the association between CA-ECPR interval and traumatic or bleeding complications.ResultsA total of 68 patients from 4 hospitals receiving ECPR for OHCA were entered into EROD and met inclusion criteria. Median age was 51 (interquartile range 38-58), 81% were male, 40% had body mass index > 30, and 70% had pre-existing medical comorbidities. A total of 65% had an initial shockable cardiac rhythm, mechanical CPR was utilized in at least 29% of patients, and 27% were discharged alive. The median time from arrest to ECPR initiation was 73 min (IQR 60-104). A total of 37% experienced a traumatic or bleeding complication, with major bleeding (32%), vascular injury (18%), and cannula site bleeding (15%) being the most common. Compared to patients with shorter CPR times, patients with a longer CA-ECPR interval had 18% (95% confidence interval - 2-42%) higher odds of suffering a mechanical or bleeding complication, but this did not reach statistical significance (p = 0.08).ConclusionsTraumatic injuries and bleeding complications are common among patients undergoing ECPR. Further study is needed to investigate the relation between arrest duration and complications. Clinicians performing ECPR should anticipate and assess for injuries and bleeding in this high-risk population.
