Abstract Background Electroencephalography (EEG) significantly contributes to the neuroprognostication after resuscitation from cardiac arrest. Recent studies suggest that the prognostic value of EEG is highest for continuous recording within the first days after cardiac arrest. Early continuous EEG, however, is not available in all hospitals. In this observational study, we sought to evaluate the predictive value of a ‘late’ EEG recording 5–14 days after cardiac arrest without sedatives. Methods We retrospectively analyzed EEG data in consecutive adult patients treated at the medical intensive care units (ICU) of the Charité—Universitätsmedizin Berlin. Outcome was assessed as cerebral performance category (CPC) at discharge from ICU, with an unfavorable outcome being defined as CPC 4 and 5. Results In 187 patients, a ‘late’ EEG recording was performed. Of these patients, 127 were without continuous administration of sedative agents for at least 24 h before the EEG recording. In this patient group, a continuously suppressed background activity < 10 µV predicted an unfavorable outcome with a sensitivity of 31% (95% confidence interval (CI) 20–45) and a specificity of 99% (95% CI 91–100). In patients with suppressed background activity and generalized periodic discharges, sensitivity was 15% (95% CI 7–27) and specificity was 100% (95% CI 94–100). GPDs on unsuppressed background activity were associated with a sensitivity of 42% (95% CI 29–46) and a specificity of 92% (95% CI 82–97). Conclusions A ‘late’ EEG performed 5 to 14 days after resuscitation from cardiac arrest can aide in prognosticating functional outcome. A suppressed EEG background activity in this time period indicates poor outcome.

Blood-based brain injury biomarkers show promise to prognosticate outcome for children resuscitated from cardiac arrest. The objective of this multicenter, observational study was to validate promising biomarkers to accurately prognosticate outcome at 1 year. Early brain injury biomarkers will be associated with outcome at one year for children with cardiac arrest. Fourteen centers in the US enrolled children aged < 18 years with in- or out-of-hospital cardiac arrest and pediatric intensive care unit admission if pre-cardiac arrest Pediatric Cerebral Performance Category score was 1-3. Glial fibrillary acidic protein (GFAP), ubiquitin carboxyl-terminal esterase L1 (UCHL1), neurofilament light (NfL), and Tau protein concentrations were measured in samples drawn post-arrest day 1 using Quanterix Simoa 4-Plex assay. The primary outcome was unfavorable outcome at one year (Vineland Adaptive Behavioral Scale < 70). Of 164 children enrolled, 120 children had evaluable data (n=50 with unfavorable outcome). Children were median (interquartile range) 1 (0-8.5) years of age, 41% female, and 60% had asphyxia etiology. Of children with unfavorable outcome, 93% had unwitnessed arrests and 43 died. While all 4 day 1 biomarkers were increased in children with unfavorable vs. favorable outcome at 1-year post-arrest, NfL had the best univariate area under the receiver operator curve to predict 1 year outcome at 0.731. In a multivariate logistic regression, NfL concentration trended toward significance on day 1 and was associated with unfavorable outcome at 1-year on days 2 and 3 (day 1: Odds Ratio [95% Confidence Interval] 1.004 [1.000-1.008], p=.062; day 2: 1.005 [1.002-1.008], p=.003, and day 3: 1.002 [1.001-1.004], p=.003, respectively). UCHL1 was associated with outcome on days 2: 1.005 [1.002-1.009], p=.003 and 3: 1.001 [1.000-1.002], p=.019) and Tau trended toward association with outcome on days 2: 1.003 [1.000-1.005], p=.08) and 3: 1.001 [1.000-1.002], p=.077. Brain injury biomarkers predict unfavorable outcome post-pediatric cardiac arrest. Accuracy of biomarkers alone and together with other prognostication tools should be evaluated to predict long term child centered outcomes post-cardiac arrest.

Objectives: Current prognostication guidelines for cardiac arrest (CA) survivors predate the use of therapeutic hypothermia (TH). The prognostic value and ideal timing of the neurological examination remain unknown in the setting of TH. Design: Patients (N = 291) admitted between 2007 and 2015 to Columbia University intensive care units for TH following CA had neurological examinations performed on days 1, 3, 5, and 7 postarrest. Absent pupillary light response (PLR), absent corneal reflexes (CRs), and Glasgow coma scores motor (GCS-M) no better than extension were considered poor examinations. Poor outcome was recorded as cerebral performance category score ≥3 at discharge and 1 year. Predictive values of examination maneuvers were calculated for each time point. Main Results: Among the 137 survivors to day 7, sensitivities and negative predictive values were low at all time points. The PLR had false positive rates (FPRs) of 0% and positive predictive values (PPV) of 100% from day 3 onward. For the CR and GCS-M, the FPRs decreased from day 3 to 5 (9% vs 3%; 21% vs 9%), while PPVs increased (91% vs 96%; 90% vs 95%). Excluding patients who died due to withdrawal of life-sustaining therapy (WLST) did not significantly affect FPRs or PPVs, nor did assessing outcome at 1 year. Conclusions: A poor neurological examination remains a strong predictor of poor outcome, both at hospital discharge and at 1 year, independent of WLST. Following TH, the predictive value of the examination is insufficient at day 3 and should be delayed until at least day 5, with some additional benefit beyond day 5.

Introduction: Extracorporeal cardiopulmonary resuscitation (ECPR) has been reported to be effective in out-of-hospital cardiac arrest (OHCA) patients in whom ventricular fibrillation (VF) as an initial rhythm were refractory to conventional cardiopulmonary resuscitation (CPR). However, it remains unclear whether ECPR is effective even though cardiac rhythm would change from VF to non-VF during CPR. Methods: This multicenter prospective observational study was conducted in 46 hospitals. A total of 457 patients with OHCA aged 20-74 years in whom initial rhythm was VF and the duration from collapse to hospital arrival was within 45 minutes were originally registered. After given CPR for more than 15 minutes in hospital, these patients received combination therapy with ECPR including therapeutic hypothermia (TH), or not received. The patients underwent ECPR (n=250) were classified into the following 2 groups according to rhythm changes during CPR; Group-A (sustained VF; n=127) and Group-B (changing from VF initially to non-shockable rhythm; n=123). The endpoint was a favorable outcome defined as Cerebral Performance Category 1-2 at 6 months after collapse. Results: There were no significant differences of age, sex, time from collapse to ECPR start and the rate of TH between the 2 groups. The rate achieving favorable outcome was significantly higher in Group-A than Group-B. (19.7% vs. 3.3%, p<0.001) (Figure1). When focusing on sustained VF (Group-A), the rate achieving favorable outcome improved about 5.5-fold by ECPR (ECPR, n=127; 19.7% vs. non-ECPR, n=55; 3.6%, p<0.001) (Figure2). In the multivariate logistic-regression analysis, sustained VF during CPR was the strongest predictor for the favorable outcomes among the pre-hospital parameters including age, bystander CPR and time from collapse to ECPR (Odds ratio 4.43, p=0.018). Conclusions: These findings indicates that the patients with sustained VF seem to be a particular population that could merit ECPR.

Introduction: Several studies have shown that the alpha-delta ratio (ADR) is associated with ischemic brain injury. Recently, an animal study has revealed that the ADR reaches the maximum point at 11 hours after ROSC, followed by downward curve (ADR peak) in the continuous EEG recordings of the rats with good outcome after cardiac arrest. We examined the existence of the early ADR peak after cardiac arrest in human. Methods: This is a prospective, observational study. Forty patients who survived out-of-hospital cardiac arrest underwent 33°C-targeted temperature management. We induced 33°C within 5 hours after ROSC and maintained for 24 hours, followed by 12 hours of rewarming period. All patients received sedative and paralytic agents until the restoration of normothermia. We started continuous EEG monitoring within 20 hours after ROSC until 72 hours after ROSC or mental recovery. We calculated alpha (8 - 13 Hz) and delta (0.5 - 4 Hz) frequency bands and computed ADR in the bifrontal channel (F3 - F4), bicentral channel (C3 - C4) and biparietal channel (P3 - P4). We did not remove artifact nor seizure events. Therefore, the whole continuous recordings were analyzed. Good neurologic outcome was defined as cerebral performance category 1 and 2 one month after ROSC. Results: Twenty-five patients showed poor outcome, while 15 patients showed good outcome. The figure is showing mean ADR ± SD change over time. The ADR reaches its highest amplitude 10 hours after ROSC and gradually decreases in the patients with good outcome regardless of the recording channel. However, the 10-hour ADR was not significantly different between the groups due to the large variances. Conclusions: Similar to the rats, the ADR peak appears early in the human patients with good outcome. However, due to the highly variable trend, application of ADR peak as a prognostic marker is limited. Regardless, the ADR implicates the crucial window of brain recovery time and remains an important subject requiring further study.

ObjectiveTo determine the additional value of EEG reactivity (EEG-R) testing to EEG background pattern for prediction of good outcome in adult patients after cardiac arrest (CA).MethodsIn this post hoc analysis of a prospective cohort study, EEG-R was tested twice a day, using a strict protocol. Good outcome was defined as a Cerebral Performance Category score of 1–2 within 6 months. The additional value of EEG-R per EEG background pattern was evaluated using the diagnostic odds ratio (DOR). Prognostic value (sensitivity and specificity) of EEG-R was investigated in relation to time after CA, sedative medication, different stimuli, and repeated testing.ResultsBetween 12 and 24 hours after CA, data of 108 patients were available. Patients with a continuous (n = 64) or discontinuous (n = 19) normal voltage background pattern with reactivity were 3 and 8 times more likely to have a good outcome than without reactivity (continuous: DOR, 3.4; 95% confidence interval [CI], 0.97–12.0; p = 0.06; discontinuous: DOR, 8.0; 95% CI, 1.0–63.97; p = 0.0499). EEG-R was not observed in other background patterns within 24 hours after CA. In 119 patients with a normal voltage EEG background pattern, continuous or discontinuous, any time after CA, prognostic value was highest in sedated patients (sensitivity 81.3%, specificity 59.5%), irrespective of time after CA. EEG-R induced by handclapping and sternal rubbing, especially when combined, had highest prognostic value. Repeated EEG-R testing increased prognostic value.ConclusionEEG-R has additional value for prediction of good outcome in patients with discontinuous normal voltage EEG background pattern and possibly with continuous normal voltage. The best stimuli were clapping and sternal rubbing.

Objective: To study the effect of short-term use of oral contraceptive pills on intra-ocular pressures of women of childbearing age.   Methods: It was a comparative observational study, conducted at Arif memorial teaching hospital and Allied hospital Faisalabad for a period of six months. Hundred female subjects were divided into two groups of 50 each. Group A, included females, who had been taking oral contraceptive pills (OCP) for more than 6 months and less than 36 months. Group B, included 50 age-matched controls, who had never used OCP. Ophthalmic and systemic history was taken. Careful Slit lamp examination was performed and intraocular pressures (IOP) were measured using Goldman Applanation tonometer. Fundus examination was done to rule out any posterior segment disease. After collection of data, we analyzed and compared the intra ocular pressures between the two groups by using ANOVA in SPSS version 21.   Results: Average duration of using OCP was 14.9 months. There was no significant difference of Cup to Disc ratios between the two groups (p= 0.109). However, significant difference was noted between the IOP of OCP group and controls. (p=0.000). Conclusion: OCP significantly increase IOP even when used for short time period.

Background: Impella CP is a left ventricular pump which may serve as a circulatory support during cardiopulmonary resuscitation (CPR) for cardiac arrest (CA). Nevertheless, the survival rate and factors associated with survival in patients undergoing Impella insertion during CPR for CA are unknown. Methods: We performed a retrospective multicenter international registry of patients undergoing Impella insertion during on-going CPR for in- or out-of-hospital CA. We recorded immediate and 30-day survival with and without neurologic impairment using the cerebral performance category score and evaluated the factors associated with survival. Results: Thirty-five patients had an Impella CP implanted during CPR for CA. Refractory ventricular arrhythmias were the most frequent initial rhythm (65.7%). In total, 65.7% of patients immediately survived. At 30 days, 45.7% of patients were still alive. The 30-day survival rate without neurological impairment was 37.1%. In univariate analysis, survival was associated with both an age < 75 years and a time from arrest to CPR ≤ 5 min (p = 0.035 and p = 0.008, respectively). Conclusions: In our multicenter registry, Impella CP insertion during ongoing CPR for CA was associated with a 37.1% rate of 30-day survival without neurological impairment. The factors associated with survival were a young age and a time from arrest to CPR ≤ 5 min.

Abstract Background Cardiopulmonary resuscitation (CPR) manoeuvres involve vigorous compressions with the proper depth and rate in order to keep sufficient perfusion to organs, especially the brain. Accordingly, high incidences of CPR-related injuries (CPR-RI) have been observed in survivors after cardiac arrest (CA). Purpose To analyse whether CPR-related injuries have an impact on the survival and neurological outcomes of comatose survivors after CA. Methods Observational prospective database of consecutive patients (pts) admitted to the acute cardiac care unit of a tertiary university hospital after in-hospital and out-of-hospital CA (IHCA and OHCA) treated with targeted temperature management (TTM 32–34°) from August 2006 to December 2019. CPR-RI were diagnosed by reviewing medical records and analysing image studies during hospitalization. Results A total of 498 pts were included; mean age was 62.7±14.5 years and 393 (78.9%) were men. We found a total of 145 CPR-RI in 109 (21.9%) pts: 79 rib fractures, 20 sternal fractures, 5 hepatic, 5 gastrointestinal, 3 spleen, 1 kidney, 26 lung and 6 heart injuries. Demographic characteristics and cardiovascular risk factors did not differ between the non-CPR-RI group and CPR-RI group. Also, we did not find differences in CA features (Table 1). Survival at discharge was higher in the CPR-RI group [74 (67.8%) vs 188 (48.3%); p&lt;0.001]. Moreover, Cerebral Performance Category (CPC) 1–2 within a 3-month follow-up was significantly higher in the CPR-RI group [(71 (65.1%) vs 168 (43.2%); p&lt;0.001; Figure 1]. Finally, pts who recieved blood transfusions were proportionally higher in the CPR-RI group [34 (32.1%) vs 65 (16.7%)]; p=0.004). Conclusions In our cohort, the presence of CPR-RI was associated with higher survival at discharge and better neurological outcomes during follow-up.
