Epidemiology and outcome predictors in 450 patients with hanging-induced cardiac arrest: a retrospective study

BackgroundCardiac arrest is the most life-threatening complication of attempted suicide by hanging. However, data are scarce on its characteristics and outcome predictors.MethodsThis retrospective observational multicentre study in 31 hospitals included consecutive adults admitted after cardiac arrest induced by suicidal hanging. Factors associated with in-hospital mortality were identified by multivariate logistic regression with multiple imputations for missing data and adjusted to the temporal trends over the study period.ResultsOf 450 patients (350 men, median age, 43 [34–52] years), 305 (68%) had a psychiatric history, and 31 (6.9%) attempted hanging while hospitalized. The median time from unhanging to cardiopulmonary resuscitation was 0 [0–5] min, and the median time to return of spontaneous circulation (ROSC) was 20 [10–30] min. Seventy-nine (18%) patients survived to hospital discharge. Three variables were independently associated with higher in-hospital mortality: time from collapse or unhanging to ROSC>20 min (odds ratio [OR], 4.71; 95% confidence intervals [95%CIs], 2.02–10.96; p = 0.0004); glycaemia >1.4 g/L at admission (OR, 6.38; 95%CI, 2.60–15.66; p < 0.0001); and lactate >3.5 mmol/L at admission (OR, 6.08; 95%CI, 1.71–21.06; p = 0.005). A Glasgow Coma Scale (GCS) score of >5 at admission was associated with lower in-hospital mortality (OR, 0.009; 95%CI, 0.02–0.37; p = 0.0009).ConclusionIn patients with hanging-induced cardiac arrest, time from collapse or unhanging to return of spontaneous circulation, glycaemia, arterial lactate, and coma depth at admission were independently associated with survival to hospital discharge. Knowledge of these risk factors may help guide treatment decisions in these patients at high risk of hospital mortality

Impact of routine percutaneous coronary intervention after out-of-hospital cardiac arrest due to ventricular fibrillation.

International audienceINTRODUCTION: Since 2003, we have routinely used percutaneous coronary intervention (PCI) and mild therapeutic hypothermia (MTH) to treat patients < 80 years of age after out-of-hospital cardiac arrest (OHCA) related to ventricular fibrillation. The aim of our study was to evaluate the prognostic impact of routine PCI in association with MTH and the potential influence of age. METHODS: We studied 111 consecutive patients resuscitated successfully following OHCA related to shock-sensitive rhythm. They were divided into five groups according to age: < 45 years (n = 22, group 1), 45 to 54 years (n = 27, group 2), 55 to 64 years (n = 22, group 3), 65 to 74 years (n = 23, group 4) and ≥75 years (n = 17, group 5). Emergency coronary angiography was performed in hemodynamically stable patients < 80 years old, regardless of the electrocardiogram pattern. MTH was targeted to a core temperature of 32°C to 34°C for 24 hours. RESULTS: Most patients (73%) had coronary heart disease, although its incidence in group 1 was lower than in other groups (41% versus 81%; P = 0.01). In group 1, all patients but one underwent coronary angiography, and 33% of them underwent associated PCI. In group 5, only 53% of patients underwent a coronary angiography and 44% underwent PCI. Overall in-hospital survival was 54%, ranging between 52% and 64% in groups 1 to 4 and 24% in group 5. Time from collapse to return of spontaneous circulation was associated with mortality (odds ratio (OR) = 1.05 (25th to 75th percentile range, 1.03 to 1.08); P < 0.001), whereas PCI was associated with survival (OR = 0.30 (25th to 75th percentile range, 0.11 to 0.79); P = 0.01). CONCLUSIONS: We suggest that routine coronary angiography with potentially associated PCI may favorably alter the prognosis of resuscitated patients with stable hemodynamics who are treated with MTH after OHCA related to ventricular fibrillation. Although age was not an independent cause of death, the clinical relevance of this therapeutic strategy remains to be determined in older people

Identifying early indicators of secondary peritonitis in critically ill patients with cirrhosis

International audienceAscitic fluid infection (AFI) is a life-threatening complication of cirrhosis. We aimed to identify early indicators of secondary peritonitis (SP), which requires emergency surgery, and to describe the outcomes of SP and spontaneous bacterial/fungal peritonitis (SBFP). Adults with cirrhosis and AFI admitted to 16 university or university-affiliated ICUs in France between 2002 and 2017 were studied retrospectively. Cases were identified by searching the hospital databases for relevant ICD-10 codes and hospital charts for AFI. Logistic multivariate regression was performed to identify factors associated with SP. Secondary outcomes were short-and long-term mortality and survivors' functional outcomes. Of 178 included patients (137 men and 41 women; mean age, 58 ± 11 years), 21 (11.8%) had SP, confirmed by surgery in 16 cases and by abdominal computed tomography in 5 cases. Time to diagnosis exceeded 24 h in 7/21 patients with SP. By multivariate analysis, factors independently associated with SP were ascitic leukocyte count > 10,000/mm 3 (OR 3.70; 95%CI 1.38-9.85; P = 0.009) and absence of laboratory signs of decompensated cirrhosis (OR 4.53; 95%CI 1.30-15.68; P = 0.017). The 1-year mortality rates in patients with SBFP and SP were 81.0% and 77.5%, respectively (Logrank test, P = 0.92). Patients with SP vs. SBFP had no differences in 1-year functional outcomes. This multicenter retrospective study identified two indicators of SP as opposed to SBFP in patients with cirrhosis. Using these indicators may help to provide early surgical treatment

Long-term follow-up of cardiac arrest survivors: Protocol of the DESAC (Devenir des survivants d'Arrets Cardiaques) study, a French multicentric prospective cohort

International audienceBackground: While the short-term prognosis of cardiac arrest patients - nearly 250,000 new cases per year in Europe - has been extensively studied, less is known regarding the mid and long-term outcome of survivors. Objective: The aim of the DESAC study is to describe mid- and long-term survival rate and functional status of cardiac arrest survivors, and to assess the influence of pre and intra hospital therapeutic strategies on these two outcomes. Methods: Between Jul 2015 and Oct 2018, adult patients over 18 years who were discharged alive from any intensive care units (public and private hospitals) in the Ile-de-France area (Paris and suburbs, France) after a non-traumatic cardiac arrest were screened for participation in this multicentric study. Survivors were included after they signed (or the proxies) an informed consent before discharge during initial hospitalisation. We calculated that including 600 patients in total would allow an 80% power to demonstrate a 2 years survival rate difference of 10% between patients who did and those who did not receive therapeutic hypothermia after resuscitation. Pre- and in-hospital data related to the circumstances surrounding the event and to the therapeutic interventions (such as cardio-pulmonary resuscitation, defibrillation, emergent coronary revascularization, neuroprotective therapeutics) were collected. After discharge, patients were interviewed at 3 months, 6 months and every year thereafter for a minimum follow-up of 26 months and a maximum follow-up of 48 months. Information on vital status, occurrence of cardiovascular events, medications and a comprehensive assessment of the functional status (qualitive of life as assessed by the Short-Form General Health Survey (SF36) scale, activities of daily living (ADL) scale, neurological Cerebral Performance Categories (CPC) and Overall Performance Categories (OPC) scales, socio-professional activities) were collected at follow-up interviews. Discussion: The DESAC study should provide important information regarding several dimensions of the mid and long-term prognosis of cardiac arrest survivors and on the benefit (and potentially harm) of early therapeutic strategies

Predictors of functional outcome after intraoperative cardiac arrest.

BACKGROUND: Few outcome data are available about intraoperative cardiac arrest (IOCA). The authors studied 90-day functional outcomes and their determinants in patients admitted to the intensive care unit after IOCA. METHODS: Patients admitted to 11 intensive care units in a period of 2000-2013 were studied retrospectively. The main outcome measure was a day-90 Cerebral Performance Category score of 1 or 2. RESULTS: Of the 140 patients (61 women and 79 men; median age, 60 yr [interquartile range, 46 to 70]), 131 patients (93.6%) had general anesthesia, 80 patients (57.1%) had emergent surgery, and 73 patients (52.1%) had IOCA during surgery. First recorded rhythms were asystole in 73 patients (52.1%), pulseless electrical activity in 44 patients (31.4%), and ventricular fibrillation/ventricular tachycardia in 23 patients (16.4%). Median times from collapse to cardiopulmonary resuscitation and return of spontaneous circulation were 0 min (0 to 0) and 10 min (5 to 20), respectively. Postcardiac arrest shock was identified in 114 patients (81.4%). Main causes of IOCA were preoperative complications (n = 46, 32.9%), complications of anesthesia (n = 39, 27.9%), and complications of surgical procedures (n = 36, 25.7%). On day 90, 63 patients (45.3%) were alive with Cerebral Performance Category score 1/2. Independent predictors of day-90 Cerebral Performance Category score 1/2 were day-1 Logistic Organ Dysfunction score (odds ratio, 0.78 per point; 95% CI, 0.71 to 0.87; P = 0.0001), ventricular fibrillation/tachycardia as first recorded rhythm (odds ratio, 4.78; 95% CI, 1.38 to 16.53; P = 0.013), and no epinephrine therapy during postcardiac arrest syndrome (odds ratio, 3.14; 95% CI, 1.29 to 7.65; P = 0.012). CONCLUSIONS: By day 90, 45% of IOCA survivors had good functional outcomes. The main outcome predictors were directly related to IOCA occurrence and postcardiac arrest syndrome; they suggest that the intensive care unit management of postcardiac arrest syndrome may be amenable to improvement

Targeted temperature management after intraoperative cardiac arrest: a multicenter retrospective study.

PURPOSE: Few outcome data are available about temperature management after intraoperative cardiac arrest (IOCA). We describe targeted temperature management (TTM) (32-34 degrees C) modalities, adverse events, and association with 1-year functional outcome in patients with IOCA. METHODS: Patients admitted to 11 ICUs after IOCA in 2008-2013 were studied retrospectively. The main outcome measure was 1-year functional outcome. RESULTS: Of the 101 patients [35 women and 66 men; median age, 62 years (interquartile range, 42-72)], 68 (67.3%) were ASA PS I to III and 57 (56.4%) had emergent surgery. First recorded rhythms were asystole in 44 (43.6%) patients, pulseless electrical activity in 36 (35.6%), and ventricular fibrillation/tachycardia in 20 (19.8%). Median times from collapse to cardiopulmonary resuscitation and return of spontaneous circulation (ROSC) were 0 min (0-0) and 10 min (4-20), respectively. The 30 (29.7%) patients who received TTM had an increased risk of infection (P = 0.005) but not of arrhythmia, bleeding, or metabolic/electrolyte disorders. By multivariate analysis, one or more defibrillation before ROSC was positively associated with a favorable functional outcome at 1-year (OR 3.06, 95% CI 1.05-8.95, P = 0.04) and emergency surgery was negatively associated with 1-year favorable functional outcome (OR 0.36; 95% CI 0.14-0.95, P = 0.038). TTM use was not independently associated with 1-year favorable outcome (OR 0.82; 95% CI 0.27-2.46, P = 0.72). CONCLUSIONS: TTM was used in less than one-third of patients after IOCA. TTM was associated with infection but not with bleeding or coronary events in this setting. TTM did not independently predict 1-year favorable functional outcome after IOCA in this study

A Glasgow Coma Scale (GCS) score of >5 at admission was associated with lower in-hospital mortality (OR, 0.009; 95%CI, 0.02–0.37; p = 0.0009). Conclusion: In patients with hanging-induced cardiac arrest, time from collapse or unhanging to return of spontaneous circulation, glycaemia, arterial lactate, and coma depth at admission were independently associated with survival to hospital discharge. Knowledge of these risk factors may help guide treatment decisions in these patients at high risk of hospital mortality.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Outcomes in 886 Critically Ill Patients After Near-Hanging Injury

International audienceBackground: Near-hanging experiences are life-threatening events about which few data are available. Research Question: What are the outcomes and early predictors of hospital mortality in critically ill patients who have undergone a near-hanging experience? Study Design and Methods: Adult patients who were resuscitated successfully after suicidal near-hanging injury admitted to 31 university or university-affiliated ICUs in France and Belgium between 1992 and 2014 were studied retrospectively. Patients were identified by searching the hospital databases for International Statistical Classification of Diseases and Related Health Problems, 9th and 10th revisions, codes and hospital charts for hanging. Logistic multivariate regression was performed to identify factors associated vital and functional outcomes at hospital discharge as the primary end points. Secondary outcomes were evaluation of temporal trends and identification of predictors of hospital mortality. Results: Of the 886 patients (181 women and 705 men; median age, 43 years; interquartile range, 34-52 years), 266 (30.0%) had attempted suicide previously, 600 (67.7%) had a diagnosed mental illness, and 55 (6.2%) attempted hanging while hospitalized. Median time from hanging awareness to unhanging was 0 min (interquartile range [IQR], 0-0; range, 0-82 min). Median Glasgow Coma Scale score was 3 (IQR, 3-5) at ICU admission. Hanging induced cardiac arrest in 450 of 886 patients (50.8%). Overall, 497 of 886 patients (56.1%) were alive at hospital discharge, including 479 of 497 patients (96.4%) with a favorable neurocognitive outcome (defined as a Glasgow Outcome Scale score of 4 or 5). By multivariate analysis, factors associated with hospital mortality were hanging-induced cardiac arrest (OR, 19.50; 95% CI, 7.21-60.90; P 1.4 g/L (OR, 4.34; 95% CI, 1.82-10.81; P = .0007) and of lactate level > 3.5 mmol/L (OR, 9.98; 95% CI, 4.17-25.36; P < .00001). Interpretation: The findings from this large multicenter retrospective cohort emphasize the very high mortality after hanging injury chiefly because of hanging-induced cardiac arrest. However, patients who survive near-hanging experiences achieve excellent neurocognitive recovery. Studies of early neuroprotective strategies for patients who have undergone near-hanging experiences are warranted. Trial Registry: ClinicalTrials.gov; No.: NCT04096976; URL: www.clinicaltrials.go
