Purpose: Intraoperative cardiac arrest (IOCA) is rare, unpredictable, and may result in a poor outcome. The features of IOCA during cancer surgery and factors related to survival following an IOCA were examined.Methods: This was a retrospective study of patients who had cancer surgery under general anesthesia between March 2009 and March 2021 (n = 84,615) to determine the number of patients who had an IOCA. Patients’ clinical information, cause of IOCA, hypoxemia during anesthesia, and the duration of hypotension and CPR were analyzed.Results: A total of 22 cases of IOCA occurred during cancer surgery (overall incidence: 2.6 per 10,000 surgeries). Return of spontaneous circulation was achieved in 17 patients, but only 13 survived until discharge. There were statistically significant differences between the deceased and the survival cancer patient groups in; (1) duration of hypoxemia (survival group: 5 minutes, range: 2-18 minutes; deceased group: 60 minutes, range, 22.5-120 minutes; p = 0.019); (2) duration of hypotension (survival group: 35 minutes, range, 15-55 minutes; deceased group 160 minutes, range, 140-185 minutes; p = 0.007); and (3) total duration of CPR (survival group: 3 minutes, range: 1-15 minutes; deceased group: 40 minutes, range: 19-149 minutes; p = 0.005).Conclusion: The duration of hypoxemia and hypotension prior to the onset of IOCA, as well as the duration of CPR were associated with the prognosis of IOCA, highlighting the need to reduce multiorgan damage caused by hypoxemia and hypotension during surgery in high-risk patients.

Objective: Reliable early prognostication of neurologic recovery in comatose cardiac arrest (CA) survivors remains a major clinical challenge. We hypothesized that continuous somatosensory evoked potentials (SSEP) in the immediate post-CA period could enable early quantification of cortical recovery. Methods: Pigs were instrumented for hemodynamic and SSEP monitoring. For SSEP, stimulation was applied to the right median nerve and electrodes in the brachial plexus and scalp acquired recordings. The primary cortical signal was the N20. Animals were then subjected to ventricular fibrillation CA that was left untreated for up to 4 minutes and followed by advanced cardiac life support until return of spontaneous circulation (ROSC). SSEP monitoring started before CA and continued after ROSC until SSEPs were unchanged for 60 minutes. Results: Six experiments were performed. In all animals, peripheral, subcortical, and cortical SSEPs were acquired prior to CA, demonstrating morphology similar to that of humans. Cortical potentials completely disappeared during CA. Average arrest duration was 6.9 ± 3.0 min. After ROSC, the N20 signal returned but with variable recovery rate and amplitude. The final N20 amplitude inversely trended with total duration of arrest (Figure 1). The N20 amplitude recovery over time took a logarithmic shape and ranged from 5 to 180 minutes to reach maximum (Figure 2). Conclusions: Continuous SSEP monitoring allows for quantification of cortical recovery within hours of short duration CA in a porcine model. The maximum N20 amplitude and rate of increase may be useful tools for quantifying recovery of cortical function in comatose cardiac arrest survivors.

AbstractCardiac arrest (CA) is a prominent cause of mortality worldwide. A large number of patients after post-cardiac arrest is often associated with a phase of impaired immunity. Through an asphyxial cardiac arrest rat model, we investigate the peripheral blood T cells subsets and the expressions of surface molecules after restoration of spontaneous circulation (ROSC). Sprague-Dawley rats (weight, 300-400 g) were randomly divided into cardiac arrest (CA) group and sham-operated group. CA group rats were induced by 6 minutes of asphyxia. After successful ROSC, 24 surviving rats in two groups were randomly assigned to be sacrificed (n = 8 per subgroup) at 3, 24 and 72 h. The proportion of T cells and CD4+, CD8+ subsets as well as the expression of surface molecules (CTLA-4, PD-1, CD28) on T cells were identified by flow cytometry. The protein concentrations of cytokines (TNF-α, IL-6, IL-10, IL-4, IFN-γ, IL-17A) in serum were measured by ELISA. Compared with sham-operated control group, CD3+ lymphocytes in CA group were significantly decreased at 24 and 72 h post-ROSC. The expression levels of CD28, PD-1, and CTLA-4 on T cells were markedly increased in CA groups at 24 h post-ROSC. Additionally, the concentrations of IFN-γ were significantly declined, while IL-4 was markedly elevated in the CA group at 24 and 72 h post-ROSC. T cells function is moderately changed after CA, which is associated with decreased percentage of T cells, the upregulation of co-inhibitory molecules, and the shift from T helper (Th) 1 to Th2.

Introduction: ECPR, « extracorporeal cardiopulmonary resuscitation » is a second line treatment for refractory cardiac arrest (CA), and low-flow time is clearly identified as a prognostic factor. Our prehospital ECPR team is made of a physician, an anesthetic nurse and a paramedic. During the day (8am to 6pm), the physician, specifically dedicated to the ECPR team, is on site at the EMS call center, where he can have other clinical or research activities; at night and during the weekend, he is on call at home. The nurse and paramedic are on site 24/7, dedicated to the mobile ICU activities, but available for the ECPR team if necessary. Triggering of the ECPR team occurs as early as possible after cardiac arrest, if possible at the same time as the BLS and ALS teams are sent out. Our ECPR team operates inside the city limits but also outside the city in surrounding cities, without access to ECPR. After ECPR team activation, cancellation can occur during transportation or on site of the CA in several situations including return of spontaneous circulation (ROSC), or absence of inclusion criteria for ECPR. Methods: Retrospective monocentric study from January to December 2017. The following data were collected: number of ECPR team activation calls, place and time of intervention, reason for cancellation, number of patients implemented with ECPR. Results: Over the 12 month period, ECPR team was activated 336 times; ECPR triggering occurred during the on call period in 185 cases (55%). Most of the time, interventions were within the city limits (N=209, 62%). Reasons for cancelation were as follows: ROSC (N=116, 34%), no inclusion criteria for ECPR (N=102, 30%), absence of CA (N=25, 7%), unknown (N=42, 12%). All together, 61 patients were actually implemented with ECPR for refractory CA (18%). Conclusion: In the end, 18% of ECPR activation calls lead to actual ECPR implementation. The necessity of early ECPR implementation justifies for early triggering of the ECPR team, despite the high risk of cancellation, whether it be for ROSC or absence of CA. This intense activity justifies for a dedicated complete ECPR team available 24/7. ECPR process requires specific training and precise coordination of personnel in the EMS call center and in the prehospital setting (ALS and ECPR teams).

A well-functioning chain of survival is critical for good outcomes following out-of-hospital cardiac arrest, a major public health concern in Singapore. While the percentage of survivors to hospital admission has increased over the years, the percentage of survivors to hospital discharge and the number of patients with good neurological recovery can be greatly improved. This underscores the urgent need to focus on ‘post-cardiac arrest care’, the fifth link in the chain of survival, to improve the outcomes of patients who are admitted to the intensive care unit (ICU) after return of spontaneous circulation. This review builds on earlier recommendations of the Singapore National Targeted Temperature Management Workgroup in 2017 to provide a focused update on post-cardiac arrest management and a practical guide for physicians managing resuscitated patients with cardiac arrest in the ICU.

AbstractThe study reported in this paper is aimed at evaluating the effectiveness of a knowledge-based expert system (ICTERUS) in diagnosing jaundiced patients, compared with a statistical system based on probabilistic concepts (TRIAL). The performances of both systems have been evaluated using the same set of data in the same number of patients. Both systems are spin-off products of the European project Euricterus, an EC-COMACBME Project designed to document the occurrence and diagnostic value of clinical findings in the clinical presentation of jaundice in Europe, and have been developed as decision-making tools for the identification of the cause of jaundice based only on clinical information and routine investigations. Two groups of jaundiced patients were studied, including 500 (retrospective sample) and 100 (prospective sample) subjects, respectively. All patients were independently submitted to both decision-support tools. The input of both systems was the data set agreed within the Euricterus Project. The performances of both systems were evaluated with respect to the reference diagnoses provided by experts on the basis of the full clinical documentation. Results indicate that both systems are clinically reliable, although the diagnostic prediction provided by the knowledge-based approach is slightly better.

Abstract Background After successful cardiopulmonary resuscitation with return of spontaneous circulation (ROSC), many patients show signs of an overactive immune activation. Monocytes are a heterogenous cell population that can be distinguished into three subsets. Purpose The aim of this prospective, observational study was to analyze whether monocyte subset distribution is associated with mortality at 6 months in patients after cardiac arrest. Methods We included 53 patients admitted to our medical ICU after cardiac arrest. Blood was taken on admission and monocyte subset distribution was analyzed by flow cytometry and distinguished into classical monocytes (CM; CD14++CD16-), intermediate monocytes (IM; CD14++CD16+CCR2+) and non-classical monocytes (NCM; CD14+CD16++CCR2-). Results Median age was 64.5 (IQR 49.8–74.3) years and 75.5% of patients were male. Mortality at 6 months was 50.9% and survival with good neurological outcome was 37.7%. Of interest, monocyte subset distribution upon admission to the ICU did not differ according to survival. However, patients that died within 6 months showed a strong increase in the pro-inflammatory subset of intermediate monocytes (8.3% (3.8–14.6)% vs. 4.1% (1.5–8.2)%; p=0.025), and a decrease of classical monocytes (87.5% (79.9–89.0)% vs. 90.8% (85.9–92.7)%; p=0.036) 72 hours after admission. In addition, intermediate monocytes were predictive of outcome independent of initial rhythm and time to ROSC and correlated with the CPC-score at 6 months (R=0.32; p=0.043). Discussion Monocyte subset distribution is associated with outcome in patients surviving a cardiac arrest. This suggests that activation of the innate immune system may play a significant role in patient outcome after cardiac arrest.

Abstract Background Despite the increasing availability of clinical data due to the digitalisation of healthcare systems, data often remain inaccessible due to the diversity of data collection systems. In the Netherlands, Cardiology Centers of the Netherlands (CCN) introduced “one-stop shop” diagnostic clinics for patients suspected of cardiac disease by their general practitioner. All CCN clinics use the same data collection system and standardised protocol, creating a large regular care database. This database can be used to describe referral practices, evaluate risk factors for cardiovascular disease (CVD) in important patient subgroups, and develop prediction models for use in daily care. Construction and content The current database contains data on all patients who underwent a cardiac workup in one of the 13 CCN clinics between 2007 and February 2018 (n = 109,151, 51.9% women). Data were pseudonymised and contain information on anthropometrics, cardiac symptoms, risk factors, comorbidities, cardiovascular and family history, standard blood laboratory measurements, transthoracic echocardiography, electrocardiography in rest and during exercise, and medication use. Clinical follow-up is based on medical need and consisted of either a repeat visit at CCN (43.8%) or referral for an external procedure in a hospital (16.5%). Passive follow-up via linkage to national mortality registers is available for 95% of the database. Utility and discussion The CCN database provides a strong base for research into historically underrepresented patient groups due to the large number of patients and the lack of in- and exclusion criteria. It also enables the development of artificial intelligence-based decision support tools. Its contemporary nature allows for comparison of daily care with the current guidelines and protocols. Missing data is an inherent limitation, as the cardiologist could deviate from standardised protocols when clinically indicated. Conclusion The CCN database offers the opportunity to conduct research in a unique population referred from the general practitioner to the cardiologist for diagnostic workup. This, in combination with its large size, the representation of historically underrepresented patient groups and contemporary nature makes it a valuable tool for expanding our knowledge of cardiovascular diseases. Trial registration: Not applicable.

Purpose: A case of loperamide-induced recurrent torsades de pointes is reported to raise awareness of an increasingly common phenomenon that could be encountered by medical providers during the current opioid epidemic. Summary: A 40 year-old-man with a prior history of opioid abuse who presented to the emergency department after taking up to 100 tablets of loperamide 2 mg daily for 5 years to blunt opioid withdrawal symptoms and was subsequently admitted to the intensive care unit for altered mental status and hyperthermia. The patient had prolonged QTc and 2 episodes of torsades de pointes (TdP) that resulted in cardiac arrest with return of spontaneous circulation. He was managed with isoproterenol, overdrive pacing, and methylnatrexone with no other events of TdP or cardiac arrest. Conclusion: A 40-year-old male who developed torsades de pointes from loperamide overdose effectively treated with overdrive pacing, isoproterenol, and methylnatrexone.

Abstract Objective Lactate has been shown to be preferentially metabolized in comparison to glucose after physiological stress, such as strenuous exercise. Derangements of lactate and glucose are common after out-of-hospital cardiac arrest (OHCA). Therefore, we hypothesized that lactate decreases faster than glucose after return-to-spontaneous-circulation (ROSC) after OHCA. Results We included 155 OHCA patients in our analysis. Within the first 8 h of presentation to the emergency department, 843 lactates and 1019 glucoses were available, respectively. Lactate decreased to 50% of its initial value within 1.5 h (95% CI [0.2–3.6 h]), while glucose halved within 5.6 h (95% CI [5.4–5.7 h]). Also, in the first 8 h after presentation lactate decreases more than glucose in relation to their initial values (lactate 72.6% vs glucose 52.1%). In patients with marked hyperlactatemia after OHCA, lactate decreased expediently while glucose recovered more slowly, whereas arterial pH recovered at a similar rapid rate as lactate. Hospital non-survivors (N = 82) had a slower recovery of lactate (P = 0.002) than survivors (N = 82). The preferential clearance of lactate underscores its role as a prime energy substrate, when available, during recovery from extreme stress.

High-quality cardiopulmonary resuscitation (CPR) is a key element in out-of-hospital cardiac arrest (OHCA) resuscitation. Mechanical CPR devices have been developed to provide uninterrupted and high-quality CPR. Although human studies have shown controversial results in favor of mechanical CPR devices, their application in pre-hospital settings continues to increase. There remains scant data on the pre-hospital use of mechanical CPR devices in Asia. Therefore, we conducted a retrospective cohort study between September 2018 and August 2020 in an urban city of Taiwan to analyze the effects of mechanical CPR devices on the outcomes of OHCA; the primary outcome was attainment of return of spontaneous circulation (ROSC). Of 552 patients with OHCA, 279 received mechanical CPR and 273 received manual CPR, before being transferred to the hospital. After multivariate adjustment for the influencing factors, mechanical CPR was independently associated with achievement of any ROSC (OR = 1.871; 95%CI:1.195–2.930) and sustained (≥24 h) ROSC (OR = 2.353; 95%CI:1.427–3.879). Subgroup analyses demonstrated that mechanical CPR is beneficial in shorter emergency medical service response time (≤4 min), witnessed cardiac arrest, and non-shockable cardiac rhythm. These findings support the importance of early EMS activation and high-quality CPR in OHCA resuscitation.
