BACKGROUND: The widespread increase in the number and types of cardiac surgery necessitate the study of frequency and risk factors of postoperative purulent-septic infections (PSIs). AIM: to provide a comparative assessment of the PSI frequency and risk factors in adult patients after various types of cardiac surgery. MATERIALS AND METHODS: Based on the cardiac surgery hospital materials, medical records of 4.815 patients over 18 years of age, who underwent open (n = 1.540) and closed (n = 3.275) heart surgeries within 1 year, were analyzed. The typical and prenosological forms of PSIs were taken into account in accordance with the epidemiological standard of case definition. RESULTS: The incidence rates for typical and prenosological PSI forms amounted to 39.6 and 72.7 per 1000 surgeries after open heart surgery, respectively, and 3.1 and 3.9 after minimally invasive endovascular surgical interventions, respectively. The main clinical forms of PSI after open and closed heart surgeries were surgical site infections, nosocomial pneumonia, urinary tract infection, and bloodstream infection. In an open heart surgery, the maximum incidence rates for typical and prenosological forms of PSIs were recorded after surgeries on the aorta and less often after heart valve replacement or coronary artery bypass grafting. The increased incidence rate after aortic surgery was mainly due to urinary tract infection and nosocomial pneumonia. In the case of closed heart surgery, no statistically significant differences were detected between the incidence rates of PSIs after coronary artery stenting, cardiac arrhythmia and carotid artery stenosis surgery, and other interventions. The duration of both the surgery itself and the subsequent patient stay in the intensive care unit was found to be important as risk factors for PSIs after cardiac surgery. CONCLUSION: The incidence rate of PSIs after open heart surgery is significantly higher than after closed heart surgery, which is mostly associated with the duration of surgical intervention and the subsequent patient stay in the intensive care unit.

Abstract Background Candida species are among the most frequent causative agents of health care–associated bloodstream infections, with mortality >40% in critically ill patients. Specific populations of critically ill patients may present peculiar risk factors related to their reason for intensive care unit admission. The primary objective of the present study was to assess the predictors of candidemia after open heart surgery. Methods This retrospective, matched case–control study was conducted in 8 Italian hospitals from 2009 to 2016. The primary study objective was to assess factors associated with the development of candidemia after open heart surgery. Results Overall, 222 patients (74 cases and 148 controls) were included in the study. Candidemia developed at a median time (interquartile range) of 23 (14–36) days after surgery. In multivariable analysis, independent predictors of candidemia were New York Heart Association class III or IV (odds ratio [OR], 23.81; 95% CI, 5.73–98.95; P < .001), previous therapy with carbapenems (OR, 8.87; 95% CI, 2.57–30.67; P = .001), and previous therapy with fluoroquinolones (OR, 5.73; 95% CI, 1.61–20.41; P = .007). Crude 30-day mortality of candidemia was 53% (39/74). Septic shock was independently associated with mortality in the multivariable model (OR, 5.64; 95% CI, 1.91–16.63; P = .002). No association between prolonged cardiopulmonary bypass time and candidemia was observed in this study. Conclusions Previous broad-spectrum antibiotic therapy and high NYHA class were independent predictors of candidemia in cardiac surgery patients with prolonged postoperative intensive care unit stay.

Background: Acute renal failure (ARF) development after cardiac surgery carries high mortality and morbidity. Methods: Out of 14 437 consecutive patients undergoing open-heart surgery between January 1991 and May 2001, 168 (1.16%) developed postoperative ARF mandating hemodialysis. Possible perioperative risk factors, and the prognosis of this dreadful, often fatal complication were investigated. Results: The mortality rate in this group was 79.7% (134 patients). The risk factors associated with postoperative ARF were advanced age (p-0.000), diabetes mellitus (p-0.000), hypertension (p-0.000), high preoperative serum creatinine levels (p-0.004), impaired left ventricular function (p-0.002), urgent operation (p-0.000) or reoperation (p-0.007), prolonged cardiopulmonary bypass (CPB) (p-0.000) and aortic cross-clamp (ACC) (p-0.000) periods, level of hypothermia (p-0.000), concomitant procedures (p-0.000), low cardiac output state (p-0.000), re-exploration for bleeding or pericardial tamponade (p-0.000), and deep sternal or systemic infection (p-0.000). Of those who could be discharged from hospital, renal functions were restored in 21 patients (12.5%); however, eight patients (4.7%) became hemodialysis dependent. The mean follow-up period was 5.79/3.2 years (range: 4 months to 13 years; a total of 195 patient-years), and 10-year survival was 58.69/10.2% in the discharged patients. Conclusions: ARF development after cardiac surgery often results in high morbidity and mortality. Recognizing risk factors permits the timely institution of proper treatment, which is the key to reducing untoward outcomes.

Dexmedetomidine-associated hyperthermia has not been previously studied. Analysis is warranted to determine whether this potentially dangerous complication is more prevalent than previously realised. We aimed to examine the association between dexmedetomidine and temperature ≥39.5°C, including patient characteristics, temporality and potential risk factors. We conducted a retrospective cohort study of all intensive care unit (ICU) admissions between 1 July 2009 and 31 May 2016 in a tertiary ICU in Australia. Temperature data was available for 9,782 ICU admissions. Dexmedetomidine was given intravenously to 611 (6.3%) patients at a dose of 0 to 1.5 g/kg/hour. Temperatures ≥39.5°C were recorded in 341 (3.5%) patients. Overall hospital mortality was 10.8% for all admissions and 29.3% for patients with temperatures ≥39.5°C. Dexmedetomidine exposure was more frequent in patients with temperature recordings ≥39.5°C compared to those with temperatures <39.5°C, 11.94% versus 2.94% (odds ratio [OR] 4.49; 95% confidence intervals [CI] 3.37, 5.92; P <0.001). The association was stronger for patients post-open heart surgery (OHS) with temperatures ≥39.5°C (OR 12.9; 95% CI 5.01, 31.62; P <0.001). Multivariate analysis showed an independent association between dexmedetomidine and a temperature ≥39.5°C in two particular patient groups: OHS (OR 2.72; 95% CI 1.1, 6.9; P <0.001), and obesity (OR 3.44; 95% CI 1.5, 7.9; P <0.001). Dexmedetomidine exposure is associated with an increased risk of hyperthermia. Possible risk factors are open heart surgery and obesity.

Relevance. The problem of purulent postoperative septic infection (the hospital acquired infection or HAI) is still one of the main cause of fatal outcomes of patients in cardiac hospitals, which demands significant material costs. The aim of the work is to evaluate the intensity of the epidemic process and risk factors for HAI among adults after various types of open heart surgery.Materials and methods. The study of medical records of 1540 patients over 18 years old, who underwent open heart surgery for the purpose of coronary artery bypass grafting (CABG), prosthetics of valves and elimination of aortic defects, was held. Typical and donozological forms of HAI were taken into account in accordance with the epidemiological standard definition of cases.Results. The incidence rates of typical and donozological forms of HAI in average was 39.6 and 72.7 per 1000 operations. The maximum incidence of HAI was detected after aortic surgery due to urinary tract infection (UTI) and hospital-acquired pneumonia.Conclusions. It was found that the increased incidence of UTI and hospital-acquired pneumonia after aortic surgery is contingent on a longer cardiosurgical operations and, accordingly, a longer stay of patients in the Department of anesthesia and resuscitation, accompanied by artificial ventilation and catheterization of the bladder, than in other cardiac operations

Abstract Background Type A aortic dissection is a very dangerous, fatal, and emergency condition for surgery. Acute aortic dissection is a rare condition, such that many patients will not survive without reconstructive surgery. Case presentation We present a case 24-year-old male who came with symptoms of shortness of breath and cough. The patient underwent ECG, chest radiology, and ultrasound, where the patient was found to have right pleural effusion while his ECG was normal. In the history taken from the patient, he had no underlying disease, no history of heart diseases in his family. For a better diagnosis, ETT and aortic CT angiography was performed on the patient which confirmed the evidence of dissection. Immediately after the diagnosis, necessary arrangements were made for open heart surgery and the patient was prepared for surgery. The patient was admitted in the cardiac surgery ICU for 5 days and his medication was carefully administered. After the conditions were stabilized, the patient was transferred to the post-cardiac surgery ICU ward. The patient was discharged from the hospital one week after the surgery and returned to the office as an OPD one week after his discharge. Conclusion Various risk factors can play a role in creating aortic dissection. Therefore, it is necessary to pay attention to patients’ history for achieving a quick and definitive diagnosis. Therefore, to control the complications of placing the cannula as well as the duration of the surgery, it is very important to reduce the duration of pumping on the patient and to be very careful during the cannula placement.

Background: Acute kidney injury (AKI) is one of the most serious complications during the postoperative period of cardiac surgery. Multiple variables predict the ARF after cardiac surgery. Objective of this study was to evaluate the significance of pre and peri-operative variables which may help in predicting the chances of developing ARF after cardiac surgery.Methods: This study was an observational, prospective study conducted among patients who were scheduled to undergo open heart surgery under cardiopulmonary bypass.Results: In total, 50 patients who underwent open-heart surgery, ARF was seen in 5 patients, with the incidence rate of 10%. Acute renal failure was present in one patient with ejection fraction <35, 2 patients had ejection fraction between 35 to 50 and 2 patients with ejection fraction >50. It was seen in 4 patients with 1-2 hrs of cardiopulmonary bypass and in 1 patient with >2 hrs of cardiopulmonary bypass. ARF was also seen in 4 patients with hematocrit between 22-26% and in 1 patient with >26%.Conclusions: The study provided a clinical variable score that can predict ARF after open-heart surgery. The score enhances the accuracy of prediction by accounting for the effect of all major risk factors of ARF.
