Elective in-patient surgery is a common occurrence among older persons and primary care physicians are routinely called on to provide preoperative assessment and perioperative risk management of these patients. Older patients undergoing noncardiac surgery may be at increased risk for cardiac or cardiovascular complications, thus perioperative assessment of risk in this population is prudent. Although the range of possible screens and diagnostic tools can make this task unwieldly, the clinical practice guidelines make it more manageable. Two guidelines in particular--one published jointly by the American College of Cardiology and American Heart Association, the other by the American College of Physicians--are particularly suited to perioperative assessment and risk management. 相似文献

Cardiovascular deaths account for about 40% of all deaths of patients with chronic kidney disease (CKD), particularly those on dialysis, while sudden cardiac death (SCD) might be responsible for as many as 60% of SCD in patients undergoing dialysis. Studies have demonstrated a number of factors occurring in hemodialysis (HD) that could lead to cardiac arrhythmias. Patients with CKD undergoing HD are at high risk of ventricular arrhythmia and SCD since changes associated with renal failure and hemodialysis-related disorders overlap. Antiarrhythmic therapy is much more difficult in patients with CKD, but the general principles are similar to those in patients with normal renal function - at first, the cause of arrhythmias should be found and eliminated. Also the choice of therapy is narrowed due to the altered pharmacokinetics of many drugs resulting from renal failure, neurotoxicity of certain drugs and their complex interactions. Cardiac pacing in elderly patients is a common method of treatment. Assessment of patients’ prognosis is important when deciding whether to implant complex devices. There are reports concerning greater risk of surgical complications, which depends also on the extent of the surgical site. The decision concerning implantation of a pacing system in patients with CKD should be made on the basis of individual assessment of the patient. 相似文献

The aims of this study were: (i) to analyze the perioperative outcomes of laparoscopic radical nephrectomy for renal cell carcinoma in patients with dialysis‐dependent end‐stage renal disease and (ii) to reveal perioperative management problems that are unique to these patients. Between June 2004 and June 2011, laparoscopic radical nephrectomy was performed in 39 patients who had renal cell carcinoma and dialysis‐dependent end‐stage renal disease. The operative outcomes of these patients were compared with the operative outcomes of 104 non‐end‐stage renal disease patients with sporadic renal cell carcinoma who underwent laparoscopic radical nephrectomy during the same period. Laparoscopic surgery was completed in thirty‐eight end‐stage renal disease patients. One patient was converted to open surgery because of an intraoperative injury to the inferior vena cava. This patient was excluded from the analysis. The mean operative time was 240 min; blood loss, 157 mL; and postoperative hospital stay, 9.6 days. Postoperative complications were observed in six patients, as follows: retroperitoneal hematoma and abscess in one patient, thrombosis of the arteriovenous fistula in three patients, pneumonia in one patient, and gastrointestinal bleeding in one patient. Eleven patients required blood transfusions. There was no significant difference between the end‐stage renal disease patients and the non‐end‐stage renal disease patients in the mean operative time or the amount of blood loss. In conclusion, laparoscopic radical nephrectomy is feasible for dialysis‐dependent end‐stage renal disease patients, as well as for non‐end‐stage renal disease patients; however, end‐stage renal disease patients may have a higher probability of experiencing non‐life‐threatening complications. 相似文献

Long-term outcomes of scleroderma renal crisis 总被引:11,自引:0,他引:11
BACKGROUND: Although scleroderma renal crisis, a complication of systemic sclerosis, can be treated with angiotensin-converting enzyme (ACE) inhibitors, its long-term outcomes are not known. OBJECTIVE: To determine outcomes, natural history, and risk factors in patients with systemic sclerosis and scleroderma renal crisis. DESIGN: Prospective observational cohort study. SETTING: University program specializing in scleroderma. PATIENTS: 145 patients with scleroderma renal crisis who received ACE inhibitors and 662 patients with scleroderma who did not have renal crisis. MEASUREMENTS: Among patients with renal crisis, the four outcomes studied were no dialysis, temporary dialysis, permanent dialysis, and early death. Demographic, clinical, and laboratory data were compared to identify risk factors for specific outcomes. Follow-up was 5 to 10 years. RESULTS: 61% of patients with renal crisis had good outcomes (55 received no dialysis, and 34 received temporary dialysis); only 4 of these (4%) progressed to chronic renal failure and permanent dialysis. More than half of the patients who initially required dialysis could discontinue it 3 to 18 months later. Survival of patients in the good outcome group was similar to that of patients with diffuse scleroderma who did not have renal crisis. Some patients (39%) had bad outcomes (permanent dialysis or early death). CONCLUSIONS: Renal crisis can be effectively managed when hypertension is aggressively controlled with ACE inhibitors. Patients should continue taking ACE inhibitors even after beginning dialysis in hopes of discontinuing dialysis. 相似文献

This article reviews the current data on mortality rates of elderly patients undergoing major thoracic and abdominal surgery, those procedures most applicable to cancer surgery. The major morbidity of surgery is discussed in relation to normal aging physiology of the heart, lungs, and kidneys. Preoperative risk assessment is discussed in relation to clinical assessment, laboratory and radiologic assessment, and the use of indexes developed to estimate surgical risk. General recommendations important in the perioperative period are given as well as specific recommendations for patients with cardiac disease, cerebrovascular disease, hypertension, thromboembolic disease, diabetes mellitus, and renal disease. 相似文献

This study aimed to compare the outcomes of laparoscopic radical nephrectomy (LRN) between patients undergoing dialysis for ≤240 and >240 months. Data from all dialysis patients with non‐metastatic renal cell carcinoma (RCC) treated with LRN between 2008 and 2015 in our hospital were evaluated retrospectively. Patients were divided into two groups, shorter‐ and longer‐term dialysis patients, according to the preoperative duration of dialysis (≤240 vs. >240 months). Of 174 patients, 58 (33.3%) were on longer‐term dialysis. Perioperative minor complications were significantly more frequent in the longer‐term dialysis patients (P = 0.03). There was no significant difference between the two groups in other perioperative outcomes. Patients on longer‐term dialysis more frequently had pathologically advanced RCC (P = 0.009) with poorer prognosis (P = 0.005). LRN for RCC in longer‐term dialysis patients appears to be safe and feasible; however, careful follow‐up is needed because these patients tend to have poorer prognosis. 相似文献

The review discusses the epidemiology and the possible underlying mechanisms of sudden cardiac death (SCD) in chronic kidney disease (CKD), and highlights the unmet clinical need for noninvasive risk stratification strategies in these patients. Although renal dysfunction shares common risk factors and often coexists with atherosclerotic cardiovascular disease, the presence of renal impairment increases the risk of arrhythmic complications to an extent that cannot be explained by the severity of the atherosclerotic process. Renal impairment is an independent risk factor for SCD from the early stages of CKD; the risk increases as renal function declines and reaches very high levels in patients with end‐stage renal disease on dialysis. Autonomic imbalance, uremic cardiomyopathy, and electrolyte disturbances likely play a role in increasing the arrhythmic risk and can be potential targets for treatment. Cardioverter defibrillator treatment could be offered as lifesaving treatment in selected patients, although selection strategies for this treatment mode are presently problematic in dialyzed patients. The review also examines the current experience with risk stratification tools in renal patients and suggests that noninvasive electrophysiological testing during dialysis may be of clinical value as it provides the necessary standardized environment for reproducible measurements for risk stratification purposes. 相似文献

Diabetic nephropathy and diabetes related nephropathies represents one of the most common causes of end‐stage renal disease (ESRD), and diabetic patients with chronic renal failure represent the most important high risk cohort of uraemic patients requiring renal replacement therapy. Interventions to slow progression of kidney disease and measures to reduce the risk of cardiovascular disease are highly effective in early renal damage and should be the main task of nephrologists, but diabetic patients are more frequently referred late to the nephrologist. Factors involved in the rate of mortality of diabetic patients with ESRD are multiple, including nutritional status, comorbidity, age, etc, but the duration and quality of pre‐dialysis nephrological care constitute a key for improving outcomes of diabetic patients with ESRD. 相似文献

Frailty in chronic kidney disease: challenges in nephrology practice. A review of current literature
Alice Kennard Nicholas Glasgow Suzanne Rainsford Girish Talaulikar 《Internal medicine journal》2023,53(4):465-472
Frailty is a multidimensional clinical syndrome characterised by low physical activity, reduced strength, accumulation of multi-organ deficits, decreased physiological reserve and vulnerability to stressors. Frailty pathogenesis and ‘inflammageing’ is augmented by uraemia, leading to a high prevalence of frailty potentially contributing to adverse outcomes in patients with advanced chronic kidney disease (CKD), including end-stage kidney disease (ESKD). The presence of frailty is a stronger predictor of CKD outcomes than estimated glomerular filtration rate and more aligned with dialysis outcomes than age. Frailty assessment should form part of routine assessment of patients with CKD and inform key medical transitions. Frailty screening and interventions in CKD/ESKD should be a research priority. 相似文献

Obstructive sleep apnea (OSA) is the most common breathing disorder, with a high prevalence in both the general and surgical populations. OSA is frequently undiagnosed, and the initial recognition often occurs during medical evaluation undertaken to prepare for surgery. Adverse respiratory and cardiovascular outcomes are associated with OSA in the perioperative period; therefore, it is imperative to identify and treat patients at high risk for the disease. In this review, we discuss the epidemiology of OSA in the surgical population and examine the available data on perioperative outcomes. We also review the identification of high-risk patients using clinical screening tools and suggest intraoperative and postoperative treatment regimens. Additionally, the role of continuous positive airway pressure in perioperative management of OSA and a brief discussion of ambulatory surgery in patients with OSA is provided. Finally, an algorithm to guide perioperative management is suggested. 相似文献

Chronic kidney disease (CKD) increased the incident cardiac implantable electronic device (CIED) infection, but risk factors of CIED infection in CKD patients remain unclear.Patients who received new CIED implantation between January 1, 1997 and December 31, 2011 were selected from the Taiwan National Health Insurance Database and were divided into 3 groups: patients with normal renal function, CKD patients without dialysis, and CKD patient with dialysis. Two outcomes, CIED infection during index hospitalization and within 1 year after discharge, were evaluated.This study included 38,354 patients, 35,060 patients in normal renal function group, 1927 patients in CKD without dialysis group, and 1367 patients in CKD with dialysis group. CKD patients without dialysis (adjusted odds ratio [aOR], 2.14, 95% confidence interval [CI], 1.32-3.46) and CKD patients with dialysis (aOR, 3.78, 95% CI, 2.37-6.02) increased incident CIED infection during index hospitalization compared to patients with normal renal function. Use of steroid (aOR: 2.74, 95% CI, 1.08-6.98) increased the risk of CIED infection in CKD patients without dialysis while chronic obstructive pulmonary disease (COPD) (aOR: 2.76, 95% CI, 1.06-7.16) increased the risk of CIED infection in CKD patient with dialysis during index hospitalization.CKD is a risk of CIED infection during index hospitalization. Use of steroid and COPD are important risks factors for CIED infection in CKD patients. 相似文献

BACKGROUND: Accurate risk factor analysis is a critical element in contemporary cardiac surgical practice. In the USA, the Society of Thoracic Surgeons Database allows institutions and individual surgeons to carry out detailed patient risk assessment and to review their cardiac surgical outcomes in a comparative fashion. METHODS: To evaluate outcomes of isolated coronary artery bypass grafting, data from all patients operated upon at the Alfred Hospital, Melbourne, Australia, over a 3 year period were entered into the Society of Thoracic Surgeons Database. RESULTS: Our results (mortality and morbidity) compared favourably with those contained within this large international database. CONCLUSION: It is hoped that a similar Australasian database can be established to facilitate a meaningful local risk assessment and a comparative analysis of outcomes of cardiac surgical procedures. 相似文献

Almost half the patients on peritoneal dialysis are diabetic and glycemic control is essential to improve both patient and technique survival. Hemoglobin A1c (HbA1c) is widely used in the general population for diabetes diagnosis and monitoring as it highly correlates with blood glucose levels and outcomes. Its use has been extrapolated to the peritoneal dialysis population, despite HbA1c being commonly underestimated. In renal failure patients, HbA1c is influenced by variables affecting not only glycemia but also hemoglobin and the time of interaction between the two. Importantly, the impact of these variables differs in peritoneal dialysis compared to non‐dialysis chronic kidney disease and hemodialysis patients. Although HbA1c in peritoneal dialysis patients is less directly associated with blood glucose levels than in the general population, studies have confirmed its association with patient mortality. In this paper we review the variables that can influence HbA1c value emphasizing their impact in peritoneal dialysis patients. By providing clinicians with a comprehensive understanding of HbA1c results, we provide them with tools for a better patient management care and potential improved outcomes of peritoneal dialysis patients. 相似文献

Dialysis immediately before liver transplantation for patients with methylmalonic academia (MMA) with the mut0 mutation is considered to be necessary to reduce plasma methylmalonic acid (MMA) levels and prevent metabolic decompensation for a successful surgical outcome; however, this has not yet been conclusively confirmed. Ten pediatric patients underwent living donor liver transplantation at the National Center for Child Health and Development, Tokyo, Japan. Seven patients received dialysis immediately before surgery, but the three most recent patients did not receive dialysis. We monitored plasma MMA levels and evaluated metabolic status during the perioperative period. Plasma MMA levels of patients who received preoperative dialysis were significantly decreased. However, lactic acidosis developed in two patients during surgery. One of the patients who had decreased renal function suffered from severe lactic acidosis after the transplantation and died on post operative day 44. In the three patients who did not receive preoperative dialysis, high plasma MMA levels persisted, but they did not develop metabolic decompensation. Their plasma MMA levels gradually decreased after transplantation. Our results indicated that reducing MMA with preoperative dialysis does not decrease the risk of metabolic decompensation. We will need to evaluate whether preoperative dialysis is necessary for the success of surgery with more cases in the future. Adequate perioperative glucose infusion and careful lactate monitoring are pivotal for success. 相似文献

Patients with chronic obstructive pulmonary disease (COPD) are at increased risk for both the development of primary lung cancer, as well as poor outcome after lung cancer diagnosis and treatment. Because of existing impairments in lung function, patients with COPD often do not meet traditional criteria for tolerance of definitive surgical lung cancer therapy. Emerging information regarding the physiology of lung resection in COPD indicates that postoperative decrements in lung function may be less than anticipated by traditional prediction tools. In patients with COPD, more inclusive consideration for surgical resection with curative intent may be appropriate as limited surgical resections or nonsurgical therapeutic options provide inferior survival. Furthermore, optimizing perioperative COPD medical care according to clinical practice guidelines including smoking cessation can potentially minimize morbidity and improve functional status in this often severely impaired patient population. 相似文献

- Transcatheter aortic valve replacement (TAVR) seems superior to surgical aortic valve replacement (SAVR) for intermediate‐term outcomes in patients with aortic stenosis and moderate to severe chronic kidney disease (CKD).
- Intermediate‐term mortality and the major adverse cardiac and renal event increase if the renal function worsens soon after TAVR or SAVR.
- Patient's demographic profile, comorbid conditions, and procedural characteristics influence the clinical outcomes emphasizing the need for careful risk assessment in deciding TAVR versus SAVR in CKD patient.

With the changing global demographic pattern, our health care systems increasingly have to deal with a greater number of elderly patients, which consequently also takes its toll on our surgical services. The elderly are not simply older adults. They represent a heterogeneous branch of the population with specific physiological, psychological, functional and social issues that require individualised attention prior to surgery. Increased acknowledgement that chronological age alone is not an exclusion criterion, along with advances in surgical and anaesthetic techniques have today lead to decreased reluctance to deny the elderly surgical treatment. In order to ensure a safe perioperative period, we believe that a comprehensive, multidisciplinary and proactive preoperative assessment will be helpful to detect the multiple risk factors and comorbidities common in older patients, to assess functional status and simultaneously allow room for early preoperative interventions and planning of the intra- and postoperative period. In this review we outline the currently available preoperative geriatric risk assessment tools and provide an insight on how a comprehensive, multidisciplinary and proactive approach can help improve perioperative outcome. 相似文献

In a rapidly expanding population of patients with chronic kidney disease, including 2 million people requiring renal replacement therapy, cardiovascular mortality is 15 times greater than the general population. In addition to traditional cardiovascular risk factors, more poorly defined risks related to uremia and its treatments appear to contribute to this exaggerated risk. In this context, the microcirculation may play an important early role in cardiovascular disease associated with chronic kidney disease. Experimentally, the uremic environment and dialysis have been linked to multiple pathways causing microvascular dysfunction. Coronary microvascular dysfunction is reflected in remote and more easily studied vascular beds such as the skin. There is increasing evidence for a correlation between systemic microvascular dysfunction and adverse cardiovascular outcomes. Systemic microcirculatory changes have not been extensively investigated across the spectrum of chronic kidney disease. Recent advances in non‐invasive techniques studying the microcirculation in vivo in man are increasing the data available particularly in patients on hemodialysis. Here, we review current knowledge of the systemic microcirculation in dialysis populations, explore whether non‐invasive techniques to study its function could be used to detect early stage cardiovascular disease, address challenges faced in studying this patient cohort and identify potential future avenues for research. 相似文献

Peripheral arterial disease (PAD) confers an elevated risk of major amputation and delayed wound healing in diabetic patients with foot ulcers. The major international vascular societies recently developed evidence‐based guidelines for the assessment and management of patients with chronic limb‐threatening ischaemia (CLTI). CLTI represents the cohort of diabetic and non‐diabetic patients who have PAD which is of sufficient severity to delay wound healing and increase amputation risk. Diabetic patients with CLTI are more likely to present with tissue loss, infection and have less favourable anatomy for revascularization than those without diabetes. Although diabetes is not consistently reported as a strong independent risk factor for limb loss, major morbidity and mortality in CLTI patients, it is impossible in clinical practice to isolate diabetes from comorbidities, such as end‐stage renal disease and coronary artery disease which occur more commonly in diabetic patients. Treatment of CLTI in the diabetic patient is complex and should involve a multi‐disciplinary team to optimize outcomes. Clinicians should use an integrated approach to management based on patient risk assessment, an assessment of the severity of the foot pathology and a structured anatomical assessment of arterial disease as suggested by the Global Vascular Guidelines for CLTI. 相似文献
