24th hour vasoactive inotrope score is associated with poor outcome in adult cardiac surgery.

OBJECTIVE: The aim of this study was to investigate the efficacy of vasoactive inotrope score at the 24th postoperative hour for mortality and morbidity in elective adult cardiac surgery. METHODS: Consecutive patients who underwent elective adult coronary artery bypass and valve surgery in a single tertiary center for cardiac surgery between December 2021 and March 2022 were prospectively included. The vasoactive inotrope score was calculated with the dosage of inotropes that were continuing at the 24th postoperative hour. Poor outcome was defined as any event of perioperative mortality or morbidity. RESULTS: The study included 287 patients, of whom 69 (24.0%) were on inotropes at the 24th postoperative hour. The vasoactive inotrope score was higher (21.6±22.5 vs. 0.94±2.7, p=0.001) in patients with poor outcome. One unit increase in the vasoactive inotrope score had an odds ratio of 1.24 (95% confidence interval: 1.14-1.35) for poor outcome. The receiver operating characteristic curve of vasoactive inotrope score for poor outcome had an area under the curve of 0.857. CONCLUSION: Vasoactive inotrope score at the 24th hour can be a very valuable parameter for risk calculation in the early postoperative period.

Microbiological Spectrum of Nosocomial ECMO Infections in a Tertiary Care Center

Abstract Introduction: Extracorporeal membrane oxygenation (ECMO) is a life-saving treatment in cardiogenic and respiratory shock. It is prone to various complications, infection being among the most frequent. This study aims to define the prevalence and characteristics of infections in ECMO patients in a tertiary care center for cardiac diseases. Methods: All ECMO patients between 2012 and 2016 in a single cardiac center were retrospectively included. Demographic data, ECMO indications, type, site, duration, and infection-related data were recorded. Data were analyzed among all patients and separately between pediatric and adult patient groups. Results: One hundred and twenty-six patients, 66 (53.4%) pediatric and 60 (47.6%) adult, received ECMO within the study period. Mean age was 3.54±4.27 years in the pediatric group and 54.92±15.57 years in the adult group. The main indication for ECMO was postcardiotomy shock (77.8%). Forty-six (36.5%) of all cases developed a culture-proven nosocomial infection with a rate of 49/1000 ECMO days. Infection was associated with > 5 days of ECMO duration and hemodialysis requirement in all patients and lower age in the pediatric group. The most frequent infection site was the lower respiratory tract (14.3%), while the most common isolated organisms were Klebsiella (8.7%) and Streptococcus (4.8%) species. Conclusion: The respiratory tract is the most common site of infection, however, all sites impose a threat to recovery, with longer treatment durations required for patients with culture-proven infections. A better understanding of the infectious spectrum and its effect on the mortality and morbidity is required for more successful treatment of ECMO patients.

Early and late results in surgical excision of primary cardiac tumors: Our single-institution experience.

BACKGROUND: In the present study, we present our experience for surgical excision for cardiac masses and to analyze survival characteristics of these patients. METHODS: Between January 2004 and December 2015, a total of 131 patients (88 females, 43 males; mean age 49.4±16.2 years; range, 1.2 months to 81 years) with primary cardiac tumors who underwent surgery in our center were included in this study. Demographic and other patient-related data were retrospectively reviewed from medical records of our center. RESULTS: All benign tumors were completely resected, whereas only palliative procedures were performed for malignant tumors. Pathology results revealed 88.5% (n=116) benign and 11.5% (n=15) malignant tumors. Tumors were most frequently located in the left atrium (76.3%, n=100), followed by the right atrium (11.5%, n=15), and the right ventricle (5.3%, n=7). Among all patients, 116 (88.5%) survived, while late mortality was seen in 15 patients (11.5%). The mean survival was 130.6±4.5 months. The latest mortality was observed at 124 months, whereby the cumulative survival rate was 79.2%. There was a statistically significant relationship between mortality and pathological characteristics of the tumor, and malignant cases had significantly higher mortality rates (p=0.002). CONCLUSION: Surgical resection of primary cardiac tumors can be performed with low morbidity and mortality rates. Although survival rates in benign tumors are satisfactory, patients with malignant tumors have poor prognosis. The main clinical predic.
