ObjectiveTo discuss the key nursing points for patients with infective endocarditis and congenital isolated kidney after valve replacement. MethodsIn December 2012, one infective endocarditis patient with isolated kidney underwent heart valve replacement in our hospital. In addition to actively preventing postoperative infection of the heart valve, our nursing focused mainly on the isolated kidney protection and monitoring, and the related complications. ResultsThe surgery was successful, and the isolated kidney was effectively protected. The patient recovered and was discharged from the hospital. ConclusionFor patients with congenital isolated kidney with infective endocarditis, patients' urine output per hour and 24 h discrepancy quantity should be closely observed after valve replacement surgery. It is also very important to intervene early and carry out comprehensive protection of the renal function.

Methods From July 2009 to February 2010, 36 patients were diagnosed to have DeBackey Ⅲ aortic dissection in our department. All patients received off-pump intervention surgery. We used sodium nitroprusside to control hypertension during the operation. Mental disorders caused by brain damage from surgery, anesthesia and other factors were ruled out. Results Five patients suffered from psychiatric disorders. Oral antihypertensive drugs were used, and we reduced the dose and shortened the time of using sodium nitroprusside. After intensive treatment and care, the symptoms of mental disorders alleviated and disappeared. Conclusion Long-term and large dose of sodium nitroprusside can easily lead to mental disorders, which requires intensive care, timely detection and treatment.
ObjectiveTo retrospectively evaluate the risk factors of mortality in postoperative acute kidney injury (AKI) patients undergoing continuous renal replacement therapy (CRRT) after cardiopulmonary bypass (CPB). MethodsWe retrospectively analyzed the clinical data of 66 patients (38 males and 28 females with mean age of 59.11±12.62 years) underwent CRRT after cardiovascular surgery in our hospital between May 2009 and June 2014. The patients were divided into a survival group (18 patients) and a death group (48 patients) according to treatment outcome at discharge. Univariate analysis for risk factors of death was carried out for preoperative characteristics and lab results among study population. Significant univariate factors were then further analyzed by multivariable logistic regression models. ResultsSignificant predictors of death included blood transfusion volume during operation, peak level of blood sugar and lactate during operation, the total bilirubin level and platelet count on the first day after operation, hypotension on the first day after operation, pulmonary infection, multiple organ dysfunction syndrome (MODS) and the interval time of oliguria and CRRT (P<0.05). Logistic regression showed that there were statistical differencs in hypotension on the first day after operation, postoperative platelet count, and interval time of oliguria and CRRT respectively (P<0.05). ConclusionImproving intraoperative management, reducing bleeding and blood transfusion, controlling blood sugar level, dealing with complications such as hypotension, pulmonary infection and MODS more aggressively, starting CRRT when needed may be helpful to reduce mortality. Monitoring of the blood pressure and platelet count on the first day after operation is useful for prognosis estimation.
Delirium is an acute, transient, usually reversible, fluctuating disturbance in consciousness, attention, cognition, and perception. Delirium after cardiac operations is associated with increased morbidity, reduced cognitive functioning, increased short-term and long-term mortality, longer hospitalization and higher hospitalization cost. The diagnosis, prevention and treatment of delirium are of great importance for perioperative care of patients undergoing cardiac surgery. Effective delirium screening tools are very helpful for the recognition and monitoring of delirium after cardiac surgery. In recent years, there has been many new strategies for the treatment, nursing care and prevention of delirium after cardiac surgery. This review focuses on the incidence, risk factors, diagnostic methods, treatment and preventive strategies of delirium after cardiac surgery.
Objective To systematically evaluate the risk factors for hypoxemia after Stanford type A aortic dissection (TAAD) surgery. Methods Electronic databases including PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, Wanfang Data, VIP and CBM were searched by computer to collect studies about risk factors for hypoxemia after TAAD published from inception to November 2021. Two authors independently assessed the studies' quality, and a meta-analysis was performed by RevMan 5.3 software. ResultsA total of 19 case-control studies involving 2 686 patients and among them 1 085 patients suffered hypoxemia, included 21 predictive risk factors. The score of Newcastle-Ottawa scale≥7 points in 16 studies. Meta-analysis showed that: age (OR=1.10, 95%CI 1.06 to 1.14, P＜0.000 01), body mass index (OR=1.87, 95%CI 1.49 to 2.34, P＜0.000 01), preoperative partial pressure of oxygen in arterial blood/fractional concentration of inspiratory oxygen (PaO2/FiO2)≤300 mm Hg (OR=7.13, 95%CI 3.48 to 14.61, P＜0.000 01), preoperative white blood cell count (OR=1.34, 95%CI 1.18 to 1.53, P＜0.000 1), deep hypothermic circulatory arrest time (OR=1.33, 95%CI 1.14 to 1.57, P=0.000 4), perioperative blood transfusion (OR=1.89, 95%CI 1.49 to 2.41, P＜0.000 01), cardiopulmonary bypass time (OR=1.02, 95%CI 1.00 to 1.03, P=0.02) were independent risk factors for hypoxemia after TAAD surgery. Preoperative serum creatinine, preoperative myoglobin, preoperative alanine aminotransferase were not associated with postoperative hypoxemia. Conclusion Current evidence shows that age, body mass index, preoperative PaO2/FiO2≤300 mm Hg, preoperative white blood cell count, deep hypothermic circulatory arrest time, perioperative blood transfusion, cardiopulmonary bypass time are risk factors for hypoxemia after TAAD surgery. These factors can be used to identify high-risk patients, and provide guidance for medical staff to develop perioperative preventive strategy to reduce the incidence of hypoxemia. The results should be validated by higher quality researches.
