ABSTRACT

First reported in 2011, the spiked helmet sign (SHS) is an electrocardiographic pattern of ST-segment elevation anecdotally associated with poor prognosis. This study aims to systematically evaluate the electrocardiographic characteristics, clinical presentations, and outcomes of all cases of SHS reported in the literature. PubMed, Scopus, Web of Science, and EMBASE were searched electronically from their inception until November 2022. The Joanna Briggs Institute Critical Appraisal Checklist for Case Reports was used to critically appraise included studies. Studies written in English describing at least one patient with SHS were included. Altogether, 26 case reports or series describing 39 patients with SHS were included. All included studies were rated of acceptable quality. Associated conditions were heterogeneous, with intracranial hemorrhagic complications being the most common (9 patients), followed by pneumothorax (6 patients) or severe pneumonia (4 patients), bowel ischemia or obstruction (6 patients), and autonomic dysfunction (3 patients with Takotsubo cardiomyopathy and 3 patients with spinal injury, cocaine overuse, and stellate gangliectomy). Two patients had multiple complications and 12 other patients suffered from sepsis, myocardial infarction, etc. Clinical outcomes were reported for 32 patients, of whom 19 (59%) died during hospitalization (6 patients with pneumothorax or pneumonia, 4 patients with intracranial hemorrhagic complications, 2 patients with bowel ischemia or obstruction, and 7 patients due to other reasons). SHS may be associated with poor prognosis, necessitating its prompt recognition by clinicians and swift evaluation for underlying causes. Larger studies are needed to elucidate its prevalence, clinical implications, and precipitating mechanisms.

ABSTRACT

OBJECTIVES: To assess the effect of vasopressin, steroid and epinephrine (VSE) combination therapy on return of spontaneous circulation (ROSC) after in-hospital cardiac arrest (IHCA), and test the conclusiveness of evidence using trial sequential analysis (TSA). METHODS: The systematic search included PubMed, EMBASE, Scopus, and Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs) that included adult patients with IHCA, with at least one group receiving combined VSE therapy were selected. Data was extracted independently by two reviewers. The main outcome of interest was ROSC. Other outcomes included survival to hospital discharge or survival to 30 and 90 days, with good neurological outcomes. RESULTS: We included a total of three RCTs (n = 869). Results showed that VSE combination therapy increased ROSC (risk ratio = 1.41; 95% CI: 1.25-1.59) as compared to placebo. TSA demonstrated that the existing evidence is conclusive. This was also validated by the alpha-spending adjusted relative risk (1.32 [1.16, 1.49], P < 0.0001). Other outcomes could not be meta-analysed due to differences in timeframe in the included studies. CONCLUSIONS: VSE combination therapy administered in cardiopulmonary resuscitation led to improved rates of ROSC. Future trials of VSE therapy should evaluate survival to hospital discharge, neurological function and long-term survival.

ABSTRACT

Objective: This meta-analysis aimed to compare clinical outcomes of warm and cold cardioplegia in cardiac surgeries in adult patients, with trial sequential analysis (TSA) used to determine the conclusiveness of the results. Methods: Electronic searches were performed on PubMed, Medline, Scopus, EMBASE, and Cochrane library to identify all studies that compared warm and cold cardioplegia in cardiac surgeries. Primary end points were in-hospital or 30-day mortality, myocardial infarction, low cardiac output syndrome, intra-aortic balloon pump use, stroke, and new atrial fibrillation. Secondary end points were acute kidney injury, hospital length of stay, and intensive care unit length of stay. Prespecified subgroup analyses were performed for (1) studies published since publication of Fan and colleagues in 2010, (2) randomized controlled studies, (3) studies with low risk of bias, (4) coronary artery bypass graft surgeries, and (5) studies with cold blood versus those with cold crystalloid cardioplegia. TSA was performed to determine conclusiveness of the results, using on all outcomes without significant heterogeneity from studies of low risk of bias. Results: No significant differences were found between post-operative rates of mortality, myocardial infarction, low cardiac output syndrome, intra-aortic balloon pump use, stroke, new atrial fibrillation, and acute kidney injury between warm and cold cardioplegia. TSA concluded that current evidence was sufficient to rule out a 20% relative risk reduction in these outcomes. Conclusions: Concerning safety outcomes, current evidence suggests that the choice between warm and cold cardioplegia remains in the surgeon's preference.

ABSTRACT

OBJECTIVE: The choice of anesthetic technique in carotid endarterectomy (CEA) has been controversial. This study compared the outcomes of general anesthesia (GA) and local anesthesia (LA) in CEA. DESIGN: Systematic review and meta-analysis of comparative studies. SETTING: Hospitals. PARTICIPANTS: Adult patients undergoing CEA with either LA or GA. INTERVENTIONS: The effects of GA and LA on CEA outcomes were compared. MEASUREMENTS AND MAIN RESULTS: PubMed, OVID, Scopus, and Embase were searched to June 2018. Thirty-one studies with 152,376 patients were analyzed. A random effect model was used, and heterogeneity was assessed with the I2 and chi-square tests. LA was associated with shorter surgical time (weighted mean difference -9.15 min [-15.55 to -2.75]; p = 0.005) and less stroke (odds ratio [OR] 0.76 [0.62-0.92]; p = 0.006), cardiac complications (OR 0.59 [0.47-0.73]; p < 0.00001), and in-hospital mortality (OR 0.72 [0.59-0.90]; p = 0.003). Transient neurologic deficit rates were similar (OR 0.69 [0.46-1.04]; p = 0.07). Heterogeneity was significant for surgical time (I2 = 0.99, chi-square = 1,336.04; p < 0.00001), transient neurologic deficit (I2 = 0.41, chi-square = 28.81; p = 0.04), and cardiac complications (I2 = 0.42, chi-square = 43.32; p = 0.01) but not for stroke (I2 = 0.22, chi-square = 30.72; p = 0.16) and mortality (I2 = 0.00, chi-square = 21.69; p = 0.65). Randomized controlled trial subgroup analysis was performed, and all the aforementioned variables were not significantly different or heterogenous. CONCLUSION: The results from this study showed no inferiority of using LA to GA in patients undergoing CEA. Future investigations should be reported more systematically, preferably with randomization or propensity-matched analysis, and thus registries will facilitate investigation of this subject. Anesthetic choice in CEA should be individualized and encouraged where applicable.

ABSTRACT

BACKGROUND: Acute heart failure is a common cause of hospital admission. This study aims to compare continuous infusion and intermittent boluses of furosemide in treating acute heart failure. METHODS: Electronic searches were performed on PubMed, Medline, Scopus, and EMBASE. English articles comparing intermittent boluses and continuous infusion of furosemide in treating acute heart failure were included. Non-comparative studies or articles, and articles that did not report specific data for acute heart failure patients were excluded. Primary endpoints included post-treatment daily urine output, weight, length of stay, and serum sodium, potassium, and creatinine. Secondary endpoints included other pre-treatment and treatment variables. Post hoc trial sequential analysis (TSA) was performed on selected variables. RESULTS: Ten randomized controlled trials were included with a total of 735 patients (371 with intermittent boluses and 364 with continuous infusion). Mean daily urine output (P < .001) and weight loss (P = .04) were significantly higher in the continuous infusion group. Other variables were not significantly different between the two groups. TSA showed that current evidence is sufficient to draw the above conclusions about mean daily urine output, but more studies were required to compare the 2 regimens in terms of weight loss. CONCLUSION: Choice of furosemide regime in acute heart failure remains physician preference. Both bolus and continuous infusion yields satisfactory outcomes.
