Prediction of duration of a patient's stay in the ICU after cardiac surgery is difficult. In 652 consecutive adult patients undergoing elective coronary artery bypass graft (CABG) surgery, we analysed prospectively preoperative and immediate postoperative variables thought to influence duration of stay in the ICU. With univariate analysis, we found that age, preoperative left ventricular ejection fraction, bypass time, aortic cross-clamp time, blood transfusions and the number of inotropic agents administered in the immediate postoperative period (for at least 6 h) were significant correlates of duration of stay in the ICU. However, logistic regression analysis showed that the number of inotropes was the most important determinant of stay in the ICU, with an overall prediction accuracy of 94.8%. The main cause of prolonged stay in the ICU (more than 2 days) was low cardiac output syndrome. We conclude that analysis of perioperative variables enhanced our ability to accurately predict duration of stay in the ICU in cardiac surgery patients. The number of inotropic agents administered during the first 6 h after operation was the most important determinant of duration of stay in the ICU.
Controlled clinical trials have shown that antimicrobial prophylaxis can lower the incidence of infection after certain operations, thus reducing morbidity, hospital stay, antibiotic usage and mortality due to sepsis. An effective prophylactic regimen should be directed against the most likely infecting organisms, but need not be active against every potential pathogen. Infection can be prevented when effective concentrations are present in the blood and the tissue during and shortly after the procedure. Therefore, antimicrobial prophylaxis should begin just before the operation: beginning earlier is unnecessary and potentially dangerous, beginning later is less effective. A single-dose prophylaxis after the induction of anesthesia is sufficient. If surgery is delayed or prolonged, a second dose is advisable if an antimicrobial drug with a short half-life is used. Postoperative administration is unnecessary and is harmful. Cephalosporins are considered to be the drug of choice, because they offer fewer allergic reactions. From the first generation cephalosporins, cefazolin has been widely recommended with success. From the second generation cephalosporins, cefuroxime, cefamandole and cefoxitin are increasingly recommended. Their antistaphylococcal activity is somewhat less strong but their activity against gram-negative bacteria is stronger. In addition, cefoxitin has good activity against anaerobes. Third generation cephalosporins, such as cefotaxime, cefoperazone, ceftriaxone, ceftazidime or ceftizoxime are generally not recommended for surgical prophylaxis. Despite these recommendations, they have been accepted by the medical community and are today in use in many countries as the most common drugs in surgical prophylaxis. Ceftriaxone in particular, is far exceeding the sales of any other drug for prophylaxis. Contra-indications, limitations, additional or other drugs and practical recommendations for specific procedures are discussed and the results of several prospective randomized studies are presented.
We concluded that a significant percentage of patients who remained in the cardiothoracic ICU for more than 9 days developed systemic candidiasis. Systemic candidiasis resulted in a significant prolongation of ICU and hospital length of stay, thus increasing extensively total hospitalization costs. Fluconazole seems to be an effective and well-tolerated agent in the treatment of severe life-threatening systemic candidiasis, and a very good alternative to amphotericin B, in cardiac surgery patients.
Objectives: Evaluation of SIRS and sepsis, in cardiac surgery patients (pts).Methods: We prospectively studied 2615 adult pts, mean aged 60.8+8.7 years, consecutively admitted to the Cardiothoracic ICU, following open heart surgery. Patients were included in the protocol if they had SIRS (hyperthermia, tachycardia, and/or leukocytosis) or clinical signs of sepsis and pathogen isolated in blood culture(s). Staphylococcus epidermidis was the predominant pathogen isolated (48.1%). 5. Mortality rate was 1.1% in SIRS group and (31.7%) in septic pts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
