    Electrical impedance tomography (EIT) can determine ventilation and perfusion relationship. Most of the data obtained so far originates from experimental settings and in healthy subjects. The aim of this study was to demonstrate that EIT measures the perioperative changes in pulmonary blood flow after repair of a ventricular septum defect in children with haemodynamic relevant septal defects undergoing open heart surgery. In a 19 bed intensive care unit in a tertiary children's hospital ventilation and cardiac related impedance changes were measured using EIT before and after surgery in 18 spontaneously breathing patients. The EIT signals were either filtered for ventilation (ΔZV) or for cardiac (ΔZQ) related impedance changes. Impedance signals were then normalized (normΔZV, normΔZQ) for calculation of the global and regional impedance related ventilation perfusion relationship (normΔZV/normΔZQ). We observed a trend towards increased normΔZV in all lung regions, a significantly decreased normΔZQ in the global and anterior, but not the posterior lung region. The normΔZV/normΔZQ was significantly increased in the global and anterior lung region. Our study qualitatively validates our previously published modified EIT filtration technique in the clinical setting of young children with significant left-to-right shunt undergoing corrective open heart surgery, where perioperative assessment of the ventilation perfusion relation is of high clinical relevance.

    Sixteen children with hematological disease who had undergone allogeneic stem cell transplantation (SCT) were evaluated to determine the adverse effect of anthracycline (ATC) and cyclophosphamide (CY) used as the conditioning regimen on pre- and post-transplant cardiac function. Methods employed were resting electrocardiogram (ECG), echocardiography and {sup 123}I-BMIPP (beta-methyl-iodophenyl-pentadecanoic acid) imaging. A cumulative ATC dose over 300 mg/m{sup 2}, especially over 400 mg/m{sup 2}, was predictable for pre-transplant abnormal findings by parameters such as uptake score (US) and heart mediastinum ratio (H/M). However, the cumulative ATC dose and pre-transplant mild abnormal cardiac findings did not correlate with post-transplant cardiac function. A 200 mg/kg dose of CY was predictable for decreased summated QRS amplitude (QRS sum) and left ventricular mass index (LVMI), however, there was no correlation between the CY dose and the values obtained through BMIPP imaging. Moreover, the CY dose was not a risk factor for worsening post-transplant fractional shortening (FS) as evaluated by echocardiography. In summary, {sup 123}I-BMIPP imaging was useful for evaluating subclinical cardiac damage due to ATC before transplant, but not for predicting cardiac damage during the course of SCT. (author)

    Children diagnosed with congenital heart disease often undergo cardiac catheterization for their treatment, which involves the use of ionizing radiation and therefore a risk of radiation-induced cancer. The purpose of this study was to calculate the effective and equivalent organ doses (H{sub T}) in those children and estimate the risk of exposure-induced death. Fifty-three children were divided into three groups: atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA). In all procedures, the exposure conditions and the dose-area product meters readings were recorded for each individual acquisition. Monte Carlo simulations were run using the PCXMC 2.0 code and mathematical phantoms simulating a child's anatomy. The H{sub T} values to all irradiated organs and the resulting E and risk of exposure-induced death values were calculated. The average dose-area product values were, respectively, 40 {+-} 12 Gy.cm{sup 2} for the ASD, 17.5 {+-} 0.7 Gy.cm{sup 2} for the VSD and 9.5 {+-} 1 Gy.cm{sup 2} for the PDA group. The average E values were 40 {+-} 12, 22 {+-} 2.5 and 17 {+-} 3.6 mSv for ASD, VSD and PDA groups, respectively. The respective estimated risk of exposure-induced death values per procedure were 0.109, 0.106 and 0.067%. Cardiac catheterizations in children involve a considerable risk for radiation-induced cancer that has to be further reduced. (orig.)

  7. Cardiac tumours in children

    Full Text Available Abstract Cardiac tumours are benign or malignant neoplasms arising primarily in the inner lining, muscle layer, or the surrounding pericardium of the heart. They can be primary or metastatic. Primary cardiac tumours are rare in paediatric practice with a prevalence of 0.0017 to 0.28 in autopsy series. In contrast, the incidence of cardiac tumours during foetal life has been reported to be approximately 0.14%. The vast majority of primary cardiac tumours in children are benign, whilst approximately 10% are malignant. Secondary malignant tumours are 10–20 times more prevalent than primary malignant tumours. Rhabdomyoma is the most common cardiac tumour during foetal life and childhood. It accounts for more than 60% of all primary cardiac tumours. The frequency and type of cardiac tumours in adults differ from those in children with 75% being benign and 25% being malignant. Myxomas are the most common primary tumours in adults constituting 40% of benign tumours. Sarcomas make up 75% of malignant cardiac masses. Echocardiography, Computing Tomography (CT and Magnetic Resonance Imaging (MRI of the heart are the main non-invasive diagnostic tools. Cardiac catheterisation is seldom necessary. Tumour biopsy with histological assessment remains the gold standard for confirmation of the diagnosis. Surgical resection of primary cardiac tumours should be considered to relieve symptoms and mechanical obstruction to blood flow. The outcome of surgical resection in symptomatic, non-myxomatous benign cardiac tumours is favourable. Patients with primary cardiac malignancies may benefit from palliative surgery but this approach should not be recommended for patients with metastatic cardiac tumours. Surgery, chemotherapy and radiotherapy may prolong survival. The prognosis for malignant primary cardiac tumours is generally extremely poor.

  8. Perioperative Education of Patient Undergoing Cardiac Surgery

    Full Text Available In recent years, the number of patients undergoing cardiac surgeries is steadily increasing. In Greece, approximately 10,500 patients per year are admitted to some kind of cardiac operation. Constant evolution of heart surgery techniques calls for adaptation of the perioperative nursing care given. Patient education, as an important part of the perioperative care, is directly related to the reduction of postoperative complications and stress management, thus promoting the patient's overall postoperative well-being. Aim: The aim of this review was to present the most important aspects of the patient's perioperative education and the role that the nurse has to play in it. Methods: Data from selected articles were extracted from Pubmed, Chinahl and Cohrane, as well as from non-electronically published scientific studies ranging from 1998-2010 and 2003-2008 respectively. Results: According to the literature, perioperative patient education can be implemented in various ways, such as through verbal updates, the use of audiovisual means and the provision of informative leaflets. The teaching topics can be divided into those of the preoperative and postoperative phase. Stress management prepares the patients psychologically and also enhances the therapeutic nurse-patient relationship. The teaching of breathing techniques and isometric exercises of the lower limbs, the cessation of smoking, the diet to be followed, as well as the management of medication, aim in the patients' physical preparation, in order to optimize their postoperative course. Conclusion: Perioperative patient education, regardless of how it is implemented, constitutes both an integral part of the nursing care and an independent nursing intervention per se, which strengthens the nurses' autonomy and improves the patient's postoperative course.

    In an attempt to determine whether noninvasive cardiac testing could be used to assess cardiac risk in patients undergoing surgery for vascular disease, the authors studied 96 patients. Seventy-seven patients eventually underwent major vascular surgery with 11 (14%) experiencing a significant cardiac complication. Thallium imaging was much more likely to be positive (p less than 0.01) in patients with a cardiac complication; however, there was a significant number of patients with cardiac complications who had a positive history or electrocardiogram for myocardial infarction. When grouped by complication and history of infarction, thallium imaging, if negative, correctly predicted low cardiac risk in the group with a history of infarction. Thallium imaging, however, did not provide a clear separation of risk in those without a history of infarction. Age and coronary angiography, on the other hand, did reveal significant differences within the group without a history of infarction. The resting radionuclide ejection fraction followed a similar pattern to thallium imaging. It is concluded that a positive history of myocardial infarction at any time in the past is the strongest risk predictor in this population and that the predictive value of noninvasive testing is dependent on this factor. Considering these findings, a proposed scheme for assessing risk that will require further validation is presented.

  11. Medanta insulin protocols in patients undergoing cardiac surgery

    Full Text Available Hyperglycemia is common in patients undergoing cardiac surgery and is associated with poor outcomes. This is a review of the perioperative insulin protocol being used at Medanta, the Medicity, which has a large volume cardiac surgery setup. Preoperatively, patients are usually continued on their preoperative outpatient medications. Intravenous insulin infusion is intiated postoperatively and titrated using a column method with a choice of 7 scales. Insulin dose is calculated as a factor of blood glucose and patient′s estimated insulin sensitivity. A comparison of this protocol is presented with other commonly used protocols. Since arterial blood gas analysis is done every 4 hours for first two days after cardiac surgery, automatic data collection from blood gas analyzer to a central database enables collection of glucose data and generating glucometrics. Data auditing has helped in improving performance through protocol modification.

    Although red blood cells(RBCs) transfusion is sometimes associated with adverse reactions,anemia could also lead to increased morbidity and mortality in highrisk patients. For these reasons,the definition of perioperative strategies that aims to detect and treat preoperative anemia,prevent excessive blood loss,and define "optimal" transfusion algorithms is crucial. Although the treatment with preoperative iron and erythropoietin has been recommended in some specific conditions,several controversies exist regarding the benefit-to-risk balance associated with these treatments. Further studies are needed to better define the indications,dosage,and route of administration for preoperative iron with or without erythropoietin supplementation. Although restrictive transfusion strategies in patients undergoing cardiac surgery have been shown to effectively reduce the incidence and the amount of RBCs transfusion without increase in side effects,some high-risk patients(e.g.,symptomatic acute coronary syndrome) could benefit from higher hemoglobin concentrations. Despite all efforts made last decade,a significant amount of work remains to be done to improve hemoglobin optimization and transfusion strategies in patients undergoing cardiac surgery.

    Purpose: Recently, performance of cardiac surgery in hemodialysis patients has increased, but the mortality rate is high. Methods: We retrospectively examined the early and long-term outcomes in 128 dialysis patients who underwent cardiac surgery with or without carperitide infusion and were followed for 2 years. Sixty-three patients received carperitide infusion during surgery and 65 patients did not. Results: The hospital mortality rate was 1.6% in the carperitide group and 12.3% in the non-carperitide group, being significantly lower in the carperitide group. The 2-year actuarial survival rate was 90.5% ± 3.7% in the carperitide group, and 76.9% ± 5.2% in the non-carperitide group, while the major adverse cardiovascular and cerebrovascular events (MACCE)-free rate at 2 years postoperatively was 90.5% ± 3.7% in the carperitide group and 67.7% ± 5.8% in the non-carperitide group. Conclusions: These findings suggest that carperitide improves the early postoperative outcome in dialysis patients undergoing cardiac surgery, as has already been demonstrated in non-dialysis patients. An early postoperative cardioprotective effect of carperitide and improvement of renal function in oliguric patients might have contributed to this outcome. However, this was a retrospective study, so a prospective investigation is required to demonstrate the mechanisms involved. In addition, further evaluation of the long-term results would be desirable. PMID:27025780

  14. Radiation Dose Estimation for Pediatric Patients Undergoing Cardiac Catheterization

    Science.gov (United States)

    Wang, Chu

    Patients undergoing cardiac catheterization are potentially at risk of radiation-induced health effects from the interventional fluoroscopic X-ray imaging used throughout the clinical procedure. The amount of radiation exposure is highly dependent on the complexity of the procedure and the level of optimization in imaging parameters applied by the clinician. For cardiac catheterization, patient radiation dosimetry, for key organs as well as whole-body effective, is challenging due to the lack of fixed imaging protocols, unlike other common X-ray based imaging modalities. Pediatric patients are at a greater risk compared to adults due to their greater cellular radio-sensitivities as well as longer remaining life-expectancy following the radiation exposure. In terms of radiation dosimetry, they are often more challenging due to greater variation in body size, which often triggers a wider range of imaging parameters in modern imaging systems with automatic dose rate modulation. The overall objective of this dissertation was to develop a comprehensive method of radiation dose estimation for pediatric patients undergoing cardiac catheterization. In this dissertation, the research is divided into two main parts: the Physics Component and the Clinical Component. A proof-of-principle study focused on two patient age groups (Newborn and Five-year-old), one popular biplane imaging system, and the clinical practice of two pediatric cardiologists at one large academic medical center. The Physics Component includes experiments relevant to the physical measurement of patient organ dose using high-sensitivity MOSFET dosimeters placed in anthropomorphic pediatric phantoms. First, the three-dimensional angular dependence of MOSFET detectors in scatter medium under fluoroscopic irradiation was characterized. A custom-made spherical scatter phantom was used to measure response variations in three-dimensional angular orientations. The results were to be used as angular dependence

  15. Preoperative information needs of children undergoing tonsillectomy.

    2012-02-01

    AIMS AND OBJECTIVES: To identify the information needs of children undergoing tonsillectomy with reference to content of information, method of delivery, information providers and timing of information provision. BACKGROUND: Tonsillectomy can be anxiety provoking for children and preoperative preparation programmes are long recognised to reduce anxiety. However, few have been designed from the perspectives of children and to date little is known about how best to prepare children in terms of what to tell them, how to convey information to them, who can best provide information and what is the best timing for information provision. DESIGN: A qualitative descriptive study. METHOD: Data were collected from nine children (aged 6-9) using interviews supported by a write and draw technique. Data were coded and categorised into themes reflecting content, method, providers and timing of information. RESULTS: Children openly communicated their information needs especially on what to tell them to expect when facing a tonsillectomy. Their principal concerns were about operation procedures, experiencing \\'soreness\\' and discomfort postoperatively and parental presence. Mothers were viewed as best situated to provide them with information. Children were uncertain about what method of information and timing would be most helpful to them. CONCLUSION: Preoperative educational interventions need to take account of children\\'s information needs so that they are prepared for surgery in ways that are meaningful and relevant to them. Future research is needed in this area. RELEVANCE TO CLINICAL PRACTICE: Practical steps towards informing children about having a tonsillectomy include asking them what they need to know and addressing their queries accordingly. Child-centred information leaflets using a question and answer format could also be helpful to children.

    Acute kidney injury (AKI) is a major complication in children who undergo cardiopulmonary bypass surgery. We performed metabonomic analyses of urine samples obtained from 40 children that underwent cardiac surgery for correction of congenital cardiac defects. Serial urine samples were obtained from each patient prior to surgery and at 4 h and 12 h after surgery. AKI, defined as a 50% or greater rise in baseline level of serum creatinine, was noted in 21 children at 48-72 h after cardiac surgery. The principal component analysis of liquid chromatography/mass spectrometry (LC/MS) negative ionization data of the urine samples obtained 4 h and 12 h after surgery from patients who develop AKI clustered away from patients who did not develop AKI. The LC/MS peak with mass-to-charge ratio (m/z) 261.01 and retention time (tR) 4.92 min was further analyzed by tandem mass spectrometry (MS/MS) and identified as homovanillic acid sulfate (HVA-SO4), a dopamine metabolite. By MS single-reaction monitoring, the sensitivity was 0.90 and specificity was 0.95 for a cut-off value of 24 ng/microl for HVA-SO4 at 12 h after surgery. We concluded that urinary HVA-SO4 represents a novel, sensitive, and predictive early biomarker of AKI after pediatric cardiac surgery.

The objective of our study was to evaluate the correlation between continuous ScvO2 by the application of a fiber-optic oximetry catheter (PediaSat and intermittent ScvO2 by using standard blood gas measurements. These results were compared to those obtained by cerebral near infrared spectroscopy (cNIRS. Setting: Tertiary pediatric cardiac intensive care unit (PCICU. Methods and main results: A retrospective study was conducted in consecutive patients who were monitored with a 4.5 or 5.5 F PediaSat catheter into the right internal jugular vein. An in vivo calibration was performed once the patient was transferred to the PCICU and re-calibration took place every 24 hours thereafter. Each patient had a NIRS placed on the forehead. Saturations were collected every 4 hours until extubation. Ten patients with a median age of 2.2 (0.13-8.5 years and a weight of 12.4 (3.9-24 kg were enrolled. Median sampling time was 32 (19-44 hours: 64 pairs of PediaSat and ScVO2 saturations showed a poor correlation (r=0.62, 95% CI 44-75; p<0.0001 and an average difference of -0.38 with a standard deviation of 13 and 95% limits of agreement from -26 to 25.

Saturations were collected every 4 hours until extubation. Ten patients with a median age of 2.2 (0.13-8.5 years and a weight of 12.4 (3.9-24 kg were enrolled. Median sampling time was 32 (19-44 hours: 64 pairs of PediaSat and ScVO2 saturations showed a poor correlation (r=0.62, 95% CI 44-75; p<0.0001 and Bland Altman analysis for repeated measures showed an average difference of 0.34 with a standard deviation of 7,9 and 95% limits of agreement from -15 to 16. Thirty-six pairs of cNIRS and ScVO2 saturations showed a fair correlation (r=0.79, 95% CI 0.60-0.89; p<0.0001 an average difference of -1.4 with a standard deviation of 6 and 95% limits of agreement from -13 to 10. Analysis of median percentage differences between PediaSat and ScvO2 saturation over time revealed that, although not statistically significant, the change in percentage saturation differences was clinically relevant after the 8th hour from calibration (from -100 to +100%. Conclusion: PediaSat catheters showed unreliable performance in our cohort. It should be further investigated whether repeating

    Both diabetes mellitus and hyperglycemia per se are associated with negative outcomes after cardiac surgery. In this article, we review these associations, the possible mechanisms that lead to adverse outcomes, and the epidemiology of diabetes focusing on those patients requiring cardiac surgery. We also examine outpatient and perioperative management of diabetes with the same focus. Finally, we discuss our own efforts to improve glycemic management of patients undergoing cardiac surgery at our institution, including keys to success, results of implementation, and patient safety concerns.

    Full Text Available Background. Psychiatric comorbidity is common in patients with cardiovascular disease, with the literature indicating that this population may be at risk for apathy. The current study examined the prevalence of apathy in patients with cardiovascular disease and its relation to aspects of cognitive function. Methods. 123 participants from an outpatient cardiology clinic completed a brief neuropsychological battery, a cardiac stress test, and demographic information, medical history, and depression symptomatology self-report measures. Participants also completed the Apathy Evaluation Scale to quantify apathy. Results. These subjects reported limited levels of apathy and depression. Increased depressive symptomatology, history of heart attack, and metabolic equivalents were significantly correlated with apathy (P<0.05. Partial correlations adjusting for these factors revealed significant correlations between behavioral apathy and a measure of executive function and the other apathy subscale with a measure of attention. Conclusion. Findings revealed that apathy was not prevalent in this sample though associated with medical variables. Apathy was largely unrelated to cognitive function. This pattern may be a result of the mild levels of cardiovascular disease and cognitive dysfunction in the current sample. Future studies in samples with severe cardiovascular disease or neuropsychological impairment may provide insight into these associations.

    Background Awareness under general anesthesia is a serious complication which leads to psychiatric disorders. The incidence of awareness in patients undergoing cardiac surgery has been reported in as many as 1.5%-23% in foreign countries. But so far, medical literature about awareness during cardiac surgery is still rare in China. Therefore, we investigated the incidence of awareness in patients undergoing different kinds of cardiac surgery, the phases when awareness occured and the effect of cardiopulmonary bypass on the incidence of awareness in coronary artery bypass grafting in Beijing.Methods Patients' recall of awareness during cardiac surgery was assessed. One hundred patients undergoing coronary artery bypass grafting (CABG) in Chaoyang Hospital, Beijing, one hundred patients undergoing CABG and one hundred patients undergoing valve replacement or septal defect repair in Fuwai Hospital, Beijing, were interviewed 3-6 days after surgery. Every report obout patients on recall of awareness was recorded. An independent research team, blinded to patients' surgery and anesthesia, assessed every report of awareness.Results The incidence of awareness of patients received CABG under cardiopulmonary bypass (CPB), off -pump CABG, septal repair or valve replacement under CPB was 4.7% (5 of 106 cases), 9.6% (9 of 94 cases) and 4% (4 of 100 cases), respectively. CPB did not greatly affect the incidence of awareness during the period of CABG (P>0.05). The incidence of awareness of patients who received CABG under CPB did not increase significantly, in comparison with that of patients who received septal repair or valve replacement under CPB in Fuwai Hospital (P>0.05). Awareness easily occurred before bypass grafting or CPB.Conclusions Awareness mainly occurs before bypass grafting or CPB in cardiac surgery. Most cases with awareness have auditory perceptions. CPB is not a main factor which affects the incidence of awareness of CABG. Surgical types do not affect the

    Full Text Available Backgrounds and Objectives — Respiratory complications after open heart surgeries are common problems which can lead to death if not properly managed. The aim of this study was to evaluate the role of pulmonary rehabilitation before and after surgery for reducing the risk of pulmonary complications after surgery also correlations of the six-minute walk test and respiratory following open heart surgery. Material and Methods — In a randomized clinical trial, 60 patients undergoing heart surgery were divided into two groups randomly (groups A and B. In group A it was performed physiotherapy before and after chest physiotherapy surgery, but on patients in group B were done only chest physiotherapy after surgery. Effects of preoperative pulmonary rehabilitation were compared between two groups, using spirometry and six-minute walk test. Results — Thirty nine of males (65% and 21 females (35% with a mean age of 8.10±9.56 was been analyzed. The mean difference in predicted forced vital capacity (CI95%: 1.3 to 8.7 and predicted peak flow indices (CI95%: 1.9 to 9.4 of spirometery indicator was significant, also evaluation of six-minute walk test showed, mean difference in walking distant (CI95%: 8.8 to 21.0 and mean oxyhemoglobin saturation (CI95%: 0.59 to 1.67 in group A was more than group B. Inverse correlation of heart rate with forced vital capacity showed that patients with more restriction had more heart rate during the walking test. Conclusion — Pulmonary rehabilitation program before surgery is recommended to reduce complications of heart surgery. Further evaluations are necessary in relation to the sensitivity and specificity of six-minute walk test parameters alone in the evaluation of respiratory performance.

    As of 2000, more adults than children are alive with congenital heart disease. Each year, more of these adults with congenital heart disease undergo surgery. Adults with congenital heart disease require lifelong surveillance, follow-up imaging, and clinical decision making by appropriately trained and familiar physicians and extenders. Three common challenges facing adults with congenital heart disease are the neglected patient, weak programmatic infrastructure, and the planning and management of pregnancy in the adult with congenital heart disease. Many challenges must be overcome in order to establish and maintain a comprehensive medical and surgical program for adults with congenital heart disease. Three common and challenging groups of adults with congenital heart disease who may require surgery are adults requiring tricuspid valve surgery for Ebstein's malformation, those requiring reoperation for failing Fontan circulation, and those requiring pulmonary valve replacement (PVR). Surgery for Ebstein's anomaly is now offered to older patients at low risk and with good late outcome. The operation includes tricuspid valve repair or replacement and frequent concomitant procedures such as atrial septal defect closure, arrhythmia surgery (the Maze procedure), and coronary artery bypass grafting. Patients undergoing previous iterations of the Fontan operation are especially prone to arrhythmia and failing circulation. Fontan conversion with arrhythmia surgery and pacemaker therapy was developed by Constantine Mavroudis, Barbara Deal, and Carl Backer to treat these challenging patients, with the first such operation performed in 1994. Fontan conversion involves: (1) conversion of the previously created atriopulmonary connection to a total cavopulmonary connection (TCPC), extracardiac Fontan; (2) arrhythmia surgery, typically with a modified biatrial Maze procedure along with placement of an antitachycardia, dual-chamber pacemaker with steroid-eluting epicardial leads

    The cardiac status of 18 hyperthyroid (HT) children (9 black and 9 white) was evaluated by echocardiography. Mitral regurgitation (MR) was diagnosed clinically in 33% (6 of the 9 blacks). None of the 9 white children had MR. Left ventricular end-diastolic diameter (LVEDD) and volume (LVEDV) did not differ from the predicted normal (PN) based on body surface area and heart rate, except in those with MR where increased LVEDD and LVEDV were noted (p less than 0.02). LV mass was +1.75 standard deviations (sigma) of the PN (p less than 0.01), due to increased wall thickness of LVEDV. Left ventricular output (LVO) was +0.35 sigma PN (p = ns); however, when compared to that of normal children, LVO of HT was higher (p less than 0.001) due to the increased heart rate. Enhanced left ventricular contractility was suggested by increased rate of dimensional change during ejection (peak dD/dt-syst), with a mean value of -11.39 cm/sec as compared to the normal of -9.54 cm/sec (p less than 0.01). A linear multivariate regression equation differentiated the cardiac status of HT from that of normal children. Following treatment to euthyroid state, MR disappeared in 2 and became less in 4 patients. LVO, LV mass, and peak dD/dt-syst also became less. Significant cardiac changes occur in children with hyperthyroidism, which may be reversible in part after euthyroidism is restored.

Malnutrition is known as a co-morbidity factorthat might predict and influence outcomes after surgery.Objectives To evaluate the effect of malnutrition and otherassociated risk factors on post-operative outcomes in childrenwith CHDs underwent cardiac surgery.Methods We conducted a retrospective cohort study in a singlecenter tertiary pediatric cardiac intensive care unit (PCICUin Indonesia. Our cohort included all children between 5 and36 months of age undergoing congenital heart surgery withcardiopulmonary bypass from November 2011 until February2014. Outcomes measured were the length of intubation and thelength of ICU stay. Variables for potential influence investigatedwere the nutritional status, age, gender, type of cardiac anomaly(acyanotic vs. cyanotic, Aristotle score, cardiopulmonary bypasstime, aortic cross-clamp time, and Pediatric Risk of Mortality(PRISM III score.Results Out of 249 patients included, 147 (59% showedmalnourishment on admission. Malnourished patients weresignificantly younger in age, presented with an acyanotic heartdefects, and had higher PRISM III score. Additionally, they alsohad a longer mechanical ventilation time and ICU stay thanthose with a normal nutritional status. After adjusting for variousvariables using a multiple logistic regression model it could bedemonstrated that a higher Z-score for weight to age was asignificant protective factor for the intubation time of more than29 hours with an odds ratio of 0.66 (95% CI 0.48 to 0.92, P =0.012. Non-malnourished patients had a 49% significantly higherchance for extubation with a hazard ratio of 1.49 (95% CI 1.12to 1.99, P= 0.007.Conclusion Malnourishment is clearly associated in a linearfashion with longer mechanical ventilation and ICU stay.

    Full Text Available Introduction: Modulating the stress response and perioperative factors can have a paramount impact on the neurodevelopmental outcome of infants who undergo cardiac surgery utilizing cardiopulmonary bypass. Materials and Methods: In this single center prospective follow-up study, we evaluated the impact of three different anesthetic techniques on the neurodevelopmental outcomes of 19 children who previously underwent congenital cardiac surgery within their 1 st year of life. Cases were done from May 2011 to December 2013. Children were assessed using the Stanford-Binet Intelligence Scales (5 th edition. Multiple regression analysis was used to test different parental and perioperative factors that could significantly predict the different neurodevelopmental outcomes in the entire cohort of patients. Results: When comparing the three groups regarding the major cognitive scores, a high-dose fentanyl (HDF patients scored significantly higher than the low-dose fentanyl (LDF + dexmedetomidine (DEX (LDF + DEX group in the quantitative reasoning scores (106 ± 22 vs. 82 ± 15 P = 0.046. The bispectral index (BIS value at the end of surgery for the -LDF group was significantly higher than that in LDF + DEX group (P = 0.011. For the entire cohort, a strong correlation was seen between the standard verbal intelligence quotient (IQ score and the baseline adrenocorticotropic hormone level, the interleukin-6 level at the end of surgery and the BIS value at the end of the procedure with an R 2 value of 0.67 and P < 0.04. There was an inverse correlation between the cardiac Intensive Care Unit length of stay and the full-scale IQ score (R = 0.4675 and P 0.027. Conclusions: Patients in the HDF group demonstrated overall higher neurodevelopmental scores, although it did not reach statistical significance except in fluid reasoning scores. Our results may point to a possible correlation between blunting the stress response and improvement of the neurodevelopmental

    Full Text Available Background: Patients with significant bilateral carotid artery stenosis requiring urgent cardiac surgery have an increased risk of stroke and death. The optimal management strategy remains inconclusive, and the available evidence does not support the superiority of one strategy over another. Materials and Methods: A number of noninvasive strategies have been developed for minimizing perioperative stroke including continuous real-time monitoring of cerebral oxygenation with near-infrared spectroscopy (NIRS. The number of patients presenting with this combination (bilateral significant carotid stenosis requiring urgent cardiac surgery in any single institution will be small and hence there is a lack of large randomized studies. Results: This case series describes our early experience with NIRS in a select group of patients with significant bilateral carotid stenosis undergoing urgent cardiac surgery (n = 8. In contrast to other studies, this series is a single surgeon, single center study, where the entire surgery (both distal ends and proximal ends was performed during single aortic clamp technique, which effectively removes several confounding variables. NIRS monitoring led to the early recognition of decreased cerebral oxygenation, and corrective steps (increased cardiopulmonary bypass flow, increased pCO 2 , etc., were taken. Conclusion: The study shows good clinical outcome with the use of NIRS. This is our "work in progress," and we aim to conduct a larger study.

    Background Sedatives and analgesics are often administered to achieve conscious sedation for diagnostic and therapeutic procedures. Appropriate concerns have been raised regarding post procedure delirium related to peri-procedural medication in the elderly. The objective of this study was to investigate the effect of premedication on new onset delirium and procedural care in elderly patients. Methods Patients≥70 years old and scheduled for elective cardiac catheterization were randomly assigned to receive either oral diphenhydramine and diaze-pam (25 mg/5 mg) or no premedication. All patients underwent a mini mental state exam and delirium assessment using confusion assess-ment method prior to the procedure and repeated at 4 h after the procedure and prior to discharge. Patients’ cooperation during the procedure and ease of post-procedure were measured using Visual Analog Scale (VAS). The degree of alertness was assessed immediately on arrival to the floor, and twice hourly afterwards using Observer’s Assessment of Alertness/Sedation Scale (OAA/S). Results A total of 93 patients were enrolled. The mean age was 77 years, and 47 patients received premedication prior to the procedure. None of the patients in either group developed delirium. Patients’ cooperation and the ease of procedure was greater and pain medication requirement less both during and after the procedure in the pre-medicated group (P < 0.05 for both). Nurses reported an improvement with patient management in the pre-medicated group (P=0.08). Conclusions In conclusion, premedication did not cause delirium in elderly patients undergoing cardiac catheterization. The reduced pain medication requirement, perceived procedural ease and post procedure management favors premedication in elderly patients undergoing cardiac catheterization.

    Full Text Available Background. The prognostic value of cardiopulmonary exercise testing (CPET is known, but the predictive value of 6MWT in patients with heart failure (HF and patients undergoing coronary artery bypass grafting (CABG is not established yet. Objective. We conducted a systematic review exploring the prognostic value of 6MWT in HF patients undergoing cardiac surgery. The aim was to find out whether the change in the distance walked during follow-up visits was associated with prognosis. Data Source. We searched “PubMed” from January 1990 to December 2012 for any review articles or experimental studies investigating the prognostic value of 6MWT in HF patients and patients undergoing cardiac surgery. Results. 53 studies were included in the review, and they explored the role of 6MWT in cardiology, cardiac surgery, and rehabilitation. The results did not show the relation between the six-minute walk distance and adverse events after CABG. The predictive power of the distance walked for death in HF patients undergoing cardiac surgery was not found. It is not yet proved if the change in the six-minute walk distance is associated with prognosis. The predictive power of the six-minute walk distance for death in HF patients undergoing cardiac surgery remains unclear.

    Milrinone can reverse acute postischemic myocardial dysfunction after cardiopulmonary bypass, although neither the appropriate bolus dose nor its pharmacokinetics has been established for cardiac surgical patients. Consenting patients undergoing cardiac surgery received milrinone (25, 50, or 75 micrograms/kg) in an open-label, dose-escalating study if their cardiac index was plasma concentrations and pharmacokinetic analysis. Twenty-nine of 60 consenting patients had cardiac indices 15%. The 75-micrograms/kg dose was associated with a case of ventricular tachycardia. The three-compartment model better described milrinone drug disposition than the two-compartment model by both visual inspection and Schwartz-Bayesian criterion. There was only limited evidence of dose-dependence, so data from all three doses are reported together (and normalized to the 50-micrograms/kg dose). Data from one patient was discarded (samples mislabeled). Using mixed-effects nonlinear regression (for n = 28), the following volumes were determined for the three compartments: V1 = 11.1 L, V2 = 16.9 L, and V3 = 363 L. Similarly, the following clearances were estimated for the three compartments: Cl1 = 0.067 L/min, Cl2 = 1.05 L/min, and Cl3 = 0.31 L/min. The 50-micrograms/kg loading dose appeared more potent than the 25-micrograms/kg dose, and, as potent, but with possibly fewer side-effects than the 75-micrograms/kg dose. The short context-sensitive half-times of 6.7 or 10.2 min after 1- or 10-min bolus infusions underscore the need for prompt institution of a maintenance infusion when milrinone concentrations must be maintained.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:7574011

    Ketamine is a non-barbiturate cyclohexamine derivative which produces a state of sedation, immobility, analgesia, amnesia, and dissociation from the environment. One of the most important advantages of ketamine premedication is production of balanced sedation with less respiratory depression and less changes in blood pressure or heart rate. As its effects on intracranial pressure, the possible effect of ketamine on intraocular pressure has been controversial overtime. In this study, we aimed to demostrate all the advantages and possible side effects of ketamine premedication in 100 children with retinablastoma undergoing ophthalmic surgery. All the children were premedicated with ketamine 5 mg kg-1 15 minutes before the examination orally and peroperative complications, reaction to intravenous catheter insertion, need for additive dose and intraocular pressures of children were recorded. We showed that ketamine administration orally is a safe and effective way of premedication for oncologic patients undergoing examination under general anaesthesia. The incidence of agitation, anxiety at parental separation and reaction to insertion of intravenous catheter was very low while adverse side effects were seen rarely. Intraocular pressure which is very important for most of the ophthalmic surgery patients remained in normal ranges. PMID:26885101

    Anxiety about and fear of dental treatment have been recognized as sources of problems in the management of child dental patients. It has been suggested that some individuals who are fearful of or anxious about dental treatment have a constitutional vulnerability to anxiety disorders as is evidenced by the presence of multiple fears, generalized anxiety or panic disorders. Concerning the child population, maternal anxiety is considered to be a major factor affecting the behaviour of young children expecting dental intervention. The aim of the study was to the measure general anxiety of children undergoing dental intervention and to compare it with some personality characteristics, such as psychopathology, extroversion and neuroticism. The evaluated sample comprises 50 children (31 girls and 19 boys), randomly selected at the University Dental Hospital, Skopje. The mean age for girls was 11.4 (± 2.4) years, and for boys 10.7 (± 2.6) years. Two psychometric instruments were used: the General Anxiety Scale for Children (GASC) and the Eysenck Personality Questionnaire (EPQ). The study confirms the presence of a high anxiety level (evaluated with GASC) among all children undergoing dental intervention. It also confirmed differences in anxiety scores between girls and boys, girls having higher scores for anxiety. Personality characteristics (evaluated with EPQ) showed low psychopathological traits, moderate extroversion and neuroticism, but accentuated insincerity (evaluated with L scale). L scales are lower with increasing age, but P scores rise with age, which could be related to puberty. No correlation was found between personality traits (obtained scores for EPQ) and anxiety except for neuroticism, which is positively correlated with the level of anxiety. In the management of dental anxiety some response measures (psychological support, biofeedback, and relaxation techniques) are recommended. PMID:24566020

    Full Text Available The incidence and prevalence of cardiovascular disease (CVD are increasing rapidly in developing countries. Most patients with CVD do not respond to medical treatment and have to undergo cardiac surgery. This highly stressful experience results in increased levels of anxiety for patients. The objective of this review was to evaluate the efficacy of massage therapy on postoperative outcomes among patients undergoing cardiac surgery. A comprehensive literature search was made on PubMed-Medline, CINAHL, Science Direct, Scopus, Web of Science and the Cochrane library databases for original research articles published between 2000 and 2015. Original articles that reported the efficacy of massage therapy in patients undergoing cardiac surgery were included. The Cochrane data extraction form was used to extract data. A total of 297 studies were identified in the literature search. However, only seven studies were eligible for analysis. Of the seven studies, six studies demonstrated the effects of massage therapy on improving post-operative outcomes of patients, while one study found no evidence of improvement. Although the methods varied considerably, most of the studies included in this review reported positive results. Therefore, there is some evidence that massage therapy can lead to positive postoperative outcomes. Evidence of the effectiveness of massage therapy in patients undergoing cardiac surgery remains inconclusive. Additional research is needed to provide a strong evidence base for the use of massage therapy to improve post-operative outcomes and recovery among cardiac surgery patients

    Standard care of burn wounds consists of cleaning and debridement (removing devitalized tissue), followed by daily dressing changes. Children with burns undergo multiple, painful and anxiety-provoking procedures during wound care and rehabilitation. The goal of procedural sedation is safe and efficacious management of pain and emotional distress, requiring a careful and systematic approach. Achieving the best results needs understanding of the mechanisms of pain and the physiologic changes in burn patients, frequent evaluation and assessment of pain and anxiety, and administration of suitable pharmacological and nonpharmacological therapies. Pharmacological therapies provide the backbone of analgesia and sedation for procedural pain management. Opioids provide excellent pain control, but they must be administered judiciously due to their side effects. Sedative drugs, such as benzodiazepines and propofol, provide excellent sedation, but they must not be used as a substitute for analgesic drugs. Ketamine is increasingly used for analgesia and sedation in children as a single agent or an adjuvant. Nonpharmacological therapies such as virtual reality, relaxation, cartoon viewing, music, massage and hypnosis are necessary components of procedural sedation and analgesia for children. These can be combined with pharmacological techniques and are used to limit the use of drugs (and hence side effects), as well as to improve patient participation and satisfaction. In this article, we review the pathophysiologic changes associated with major thermal injury in children, the options available for sedation and analgesia for wound care procedures in these children and our institutional guidelines for procedural sedation.

    BACKGROUND: Studies on the relationship between left ventricular reverse remodeling and cardiopulmonary exercise capacity in heart failure patients undergoing cardiac resynchronization therapy (CRT) are scarce and inconclusive. METHODS AND RESULTS: Eighty-four patients with a 1st-time CRT...... response (left ventricular end-systolic volume decrease ≥15%) and a comprehensive set of CPX results was examined. Echocardiographic responders (54%) demonstrated higher peak oxygen consumption and better exercise performance than nonresponders at baseline and at 6-month follow-up. Furthermore, only...... correlates of higher average oxygen consumption during exercise, and that nonischemic etiology and smaller pre-implantation QRS width were associated with better ventilatory efficiency over time. CONCLUSIONS: During the first 6 months of CRT there was a significant positive association between reverse...

    Full Text Available Introduction: Peripheral muscle strength has been little explored in the literature in the context of cardiac rehabilitation. Objective: To evaluate the peripheral muscle strength of patients undergoing elective cardiac surgery. Methods: This was a longitudinal observational study. The peripheral muscle strength was measured using isometric dynamometry lower limb (knee extensors and flexors at three different times: preoperatively (M1, the day of discharge (M2 and hospital discharge (M3. Participants received physiotherapy pre and postoperatively during the days of hospitalization during the morning and afternoon. Results: Twenty-two patients were evaluated. The values of peripheral muscle strength of knee extensors preoperative found were about 50% lower than those predicted for the healthy population. When comparing muscle strength prior (M1, with the remaining evaluation, found himself in a fall of 29% for the movement of knee extension and 25% for knee flexion in M2 and a decrease of 10% movement for knee extension and 13% for knee flexion in M3 when comparing with M1. Conclusion: The values of peripheral muscle strength prior of the study patients were lower than predicted for the healthy population of the same age. After the surgical event this reduction is even more remarkable, being reestablished until the time of discharge, to values close to baseline.

    The aim of this study was to determine the effect of choice of invasive monitoring on cost, morbidity, and mortality in cardiac surgery. Two hundred and twenty-six adults undergoing elective cardiac surgery were initially assigned at random to receive either a central venous pressure monitoring catheter (group I), a conventional pulmonary artery (PA) catheter (group II), or a mixed venous oxygen saturation (SvO2) measuring PA catheter (group III). If the attending anesthesiologist believed that the patient initially randomized to group I should have a PA catheter, that patient was then reassigned to receive either a conventional PA catheter (group IV) or SvO2 measuring PA catheter (group V). The total costs were defined as the total amount billed to the patient for the catheter used; the professional cost of its insertion; and the determinations of cardiac output, arterial blood gas tensions, hemoglobin level, and hematocrit. Mean total monitoring and laboratory costs in Group I ($591 +/- 67) were statistically significantly (P less than 0.05) less than costs in Group II ($856 +/- 231). Further, mean monitoring and laboratory costs in Group II were statistically significantly (P less than 0.05) less than those in Group III ($1128 +/- 759). Patients in group IV incurred mean total costs of $986 +/- 578, while those in group V had mean total costs of $1126 +/- 382 (NS). There were no significant differences between any of the groups with respect to length of stay in the intensive care unit, morbidity, or mortality.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2505641

  11. Radiation Dose to the Thyroid and Gonads in Patients Undergoing Cardiac CT Angiography

    International Nuclear Information System (INIS)

    The present data show a global increase in the rate of cardiovascular disease. Cardiac CT angiography has developed as a fast and non-invasive cardiac imaging modality following the introduction of multi-slice computed tomogaraphy. The aim of this study was to measure the radiation dose to the thyroid and pelvis regions in patients undergoing cardiac CT angiography using the Care Dose 4D method of 64-slice scanner. Eighty-one patients (41 males and 40 females) who were diagnosed with suspected coronary artery disease and were referred to Golestan Hospital, Imaging Department were recruited. Inclusion criteria were based on the protocol of multi-slice CT coronary angiography. The radiation dose to the thyroid and pelvis regions was measured using thermo luminescent dosimeters (TLDs). The mean radiation dose to the thyroid in male and female subjects was 0.32 mSv and 0.41 mSv, respectively (P = 0.032) (total mean, 0.36 mSv). The mean radiation dose to the pelvis in male and female subjects was 81 μSv and 112 μSv, respectively (P = 0.026) (total mean, 96.5 μSv), The total mean radiation dose to the thyroid and gonads was 0.36 mSv, and 96.5 μSv, respectively for the subjects. These values were high for one organ in a single study. Gender can affect the radiation dose to the thyroid and gonads. This can be attributed to the anatomical characteristic differences of the male and female subjects

  12. Predicted risks of radiogenic cardiac toxicity in two pediatric patients undergoing photon or proton radiotherapy

    International Nuclear Information System (INIS)

    Hodgkin disease (HD) and medulloblastoma (MB) are common malignancies found in children and young adults, and radiotherapy is part of the standard treatment. It was reported that these patients who received radiation therapy have an increased risk of cardiovascular late effects. We compared the predicted risk of developing radiogenic cardiac toxicity after photon versus proton radiotherapies for a pediatric patient with HD and a pediatric patient with MB. In the treatment plans, each patient’s heart was contoured in fine detail, including substructures of the pericardium and myocardium. Risk calculations took into account both therapeutic and stray radiation doses. We calculated the relative risk (RR) of cardiac toxicity using a linear risk model and the normal tissue complication probability (NTCP) values using relative seriality and Lyman models. Uncertainty analyses were also performed. The RR values of cardiac toxicity for the HD patient were 7.27 (proton) and 8.37 (photon), respectively; the RR values for the MB patient were 1.28 (proton) and 8.39 (photon), respectively. The predicted NTCP values for the HD patient were 2.17% (proton) and 2.67% (photon) for the myocardium, and were 2.11% (proton) and 1.92% (photon) for the whole heart. The predicted ratios of NTCP values (proton/photon) for the MB patient were much less than unity. Uncertainty analyses revealed that the predicted ratio of risk between proton and photon therapies was sensitive to uncertainties in the NTCP model parameters and the mean radiation weighting factor for neutrons, but was not sensitive to heart structure contours. The qualitative findings of the study were not sensitive to uncertainties in these factors. We conclude that proton and photon radiotherapies confer similar predicted risks of cardiac toxicity for the HD patient in this study, and that proton therapy reduced the predicted risk for the MB patient in this study

    Acute kidney injury (AKI) is closely associated with the mortality of hospitalized patients and long-term development of chronic kidney disease, especially in children. The purpose of our study was to assess the evidence of contrast-induced AKI after cardiac catheterization in children with heart disease and evaluate the clinical usefulness of candidate biomarkers in AKI. A total of 26 children undergoing cardiac catheterization due to various heart diseases were selected and urine and blood samples were taken at 0 hr, 6 hr, 24 hr, and 48 hr after cardiac catheterization. Until 48 hr after cardiac catheterization, there was no significant increase in serum creatinine level in all patients. Unlike urine kidney injury molecule-1, IL-18 and neutrophil gelatinase-associated lipocalin, urine liver-type fatty acid-binding protein (L-FABP) level showed biphasic pattern and the significant difference in the levels of urine L-FABP between 24 and 48 hr. We suggest that urine L-FABP can be one of the useful biomarkers to detect subclinical AKI developed by the contrast before cardiac surgery.

    Cardiac imaging plays an important role in both congenital and acquired heart diseases. Cardiac computed tomography (angiography) cCT(A) is a non-invasive, increasingly popular, complementary modality to echocardiography in evaluation of congenital heart diseases (CHD) in children. Despite radiation exposure, cCT(A) is now commonly used for evaluation of the complex CHD, giving information of both intra-cardiac and extra-cardiac anatomy, coronary arteries, and vascular structures. This review article will focus on the fundamentals and essentials for performing cCT(A) in children, including radiation dose awareness, basic techniques, and strengths and weaknesses of cCT(A) compared with cardiac magnetic resonance imaging (cMRI), and applications. The limitations of this modality will also be discussed, including the CHD for which cMRI may be substituted.

  18. Non-invasive anesthesia for children undergoing proton radiation therapy

    International Nuclear Information System (INIS)

    Background: Proton therapy is a newer modality of radiotherapy during which anesthesiologists face specific challenges related to the setup and duration of treatment sessions. Purpose: Describe our anesthesia practice for children treated in a standalone proton therapy center, and report on complications encountered during anesthesia. Materials and methods: A retrospective review of anesthetic records for patients ⩽18 years of age treated with proton therapy at our institution between January 2006 and April 2013 was performed. Results: A total of 9328 anesthetics were administered to 340 children with a median age of 3.6 years (range, 0.4–14.2). The median daily anesthesia time was 47 min (range, 15–79). The average time between start of anesthesia to the start of radiotherapy was 7.2 min (range, 1–83 min). All patients received Total Intravenous Anesthesia (TIVA) with spontaneous ventilation, with 96.7% receiving supplemental oxygen by non-invasive methods. None required daily endotracheal intubation. Two episodes of bradycardia, and one episode each of; seizure, laryngospasm and bronchospasm were identified for a cumulative incidence of 0.05%. Conclusions: In this large series of children undergoing proton therapy at a freestanding center, TIVA without daily endotracheal intubation provided a safe, efficient, and less invasive option of anesthetic care

  20. Cardiac dual-source CT for the preoperative assessment of patients undergoing bariatric surgery

    International Nuclear Information System (INIS)

    Aim: To assess the diagnostic value of coronary dual-source computed tomography (DSCT) as a comprehensive, non-invasive tool in the preoperative cardiac evaluation of patients undergoing bariatric surgery. Materials and methods: Thirty consecutive obese [average body mass index (BMI): 45 ± 7.6, range: 35–59] patients (24 women; six men; median age: 52 ± 15 years) were enrolled in this institutional review board (IRB)-approved, Health Insurance Portability and Accountability Act of 1996 (HIPAA)-compliant prospective study. Calcium scoring (CaS) and electrocardiography (ECG)-gated images of the coronary arteries were obtained with a large body habitus protocol (120 kV; 430 mAs; 100 ml iodinated contrast medium at 7 ml/s injection rate) on a DSCT machine. Qualitative (four-point: 1 = excellent to 4 = not delineable) coronary segmental analysis, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) measurements were performed. The presence and degree of vascular disease (four-grade scale: mild to severe) was correlated with CaS and cardiovascular (CV) risk stratification blood tests. In patients with severe stenosis (>70%), findings were compared with cardiac nuclear medicine imaging (single photon-emission computed tomography; SPECT) imaging. Results: The average HR, enhancement, and quality score were 64 ± 7 beats/min, 288 ± 66 HU and 1.8 ± .5, respectively. Ninety-three percent (417/450) of the coronary segments were rated diagnostic. The SNRs and CNRs were 17 ± 9 and 12 ± 7 for the right coronary artery; 17 ± 8 and 12 ± 7 for the left main coronary artery; 16 ± 9 and 11 ± 7 for the left anterior descending coronary artery; and 15 ± 7 and 10 ± 6 for the left circumflex coronary artery. Ten of the 30 patients (33%) demonstrated coronary artery disease (CAD) of which two (6%) showed three-vessel disease. Four (13%) patients showed severe disease: in three of which the presence of significant stenosis was confirmed by SPECT and by catheter

    Background and Objective. Pain evaluation in children can be a difficult task, since it possesses sensory and affective components that are often hard to discriminate. Infrared thermography has previously been used as a diagnostic tool for pain detection in animals; therefore, the aim of this study was to assess the presence of temperature changes during dental extractions and to evaluate its correlation with heart rate changes as markers of pain and discomfort. Methods. Thermographic changes in the lacrimal caruncle and heart rate measurements were recorded in healthy children scheduled for dental extraction before and during the procedure and compared. Afterwards, correlation between temperature and heart rate was assessed. Results. We found significant differences in temperature and heart rate before the procedure and during the dental extraction (mean difference 4.07°C, p < 0.001, and 18.11 beats per minute, p < 0.001) and no evidence of correlation between both measurements. Conclusion. Thermographic changes in the lacrimal caruncle can be detected in patients who undergo dental extractions. These changes appear to be stable throughout time and to possess very little intersubject variation, thus making them a candidate for a surrogate marker of pain and discomfort. Future studies should be performed to confirm this claim. PMID:27445611

    2008-01-01

    Full Text Available Background. Voiding cystourethrograms are distressing for children and parents. Nonpharmacological methods reduce distress. Pharmacological interventions for VCUG focus on sedation as well as analgesia, anxiolysis, and amnesia. Sedation has cost, time, and safety issues. Which agents and route should we use? Are we sure that sedation does not influence the ability to diagnose vesicoureteric reflux? Methods. Literature search of Medline, EMBASE, and the Cochrane Database. Review of comparative studies found. Results. Seven comparative studies including two randomised controlled trials were reviewed. Midazolam given orally (0.5-0.6 mg/kg or intranasally (0.2 mg/kg is effective with no apparent effect on voiding dynamics. Insufficient evidence to recommend other sedating agents was found. Deeper sedating agents may interfere with voiding dynamics. Conclusion. Midazolam reduces the VCUG distress, causes amnesia, and does not appear to interfere with voiding dynamics. Midazolam combined with simple analgesia is an effective method to reduce distress to children undergoing VCUG.

    In the healthy heart, left ventricular (LV) filling generates flow patterns which have been proposed to optimize blood transport by coupling diastole and systole phases. We present a novel image-based method to assess how flow patterns influence LV blood transport in patients undergoing cardiac resynchronization therapy (CRT). Solving the advection equation with time-varying inflow boundary conditions allows to track the transport of blood entering the LV in the different filling waves, as well as the transport barriers which couple filling and ejection. The velocity fields were obtained using echocardiographic color Doppler velocimetry, which provides two-dimensional time-resolved flow maps in the apical long axis three-chamber view of the LV. We analyze flow transport in a group of patients with CRT devices as well as in healthy volunteers. In the patients under CRT, the device programming was varied to analyze flow transport under different values of the atrioventricular (AV) conduction delay and to model tachycardia. This analysis illustrates how CRT influences the transit of blood inside the LV, contributes to conserving kinetic energy and favors the generation of hemodynamic forces that accelerate blood in the direction of the LV outflow tract.

    Purpose: To demonstrate the dosimetric advantages of cardiac-sparing (CS) intensity modulated radiation therapy (IMRT) in children undergoing whole lung irradiation (WLI). Methods and Materials: Chest CT scans of 22 children who underwent simulation with 3-dimensional (n=10) or 4-dimensional (n=12) techniques were used for this study. Treatment planning was performed using standard anteroposterior-posteroanterior (S-RT) technique and CS-IMRT. Left and right flank fields were added to WLI fields to determine whether CS-IMRT offered any added protection to normal tissues at the junction between these fields. The radiation dose to the lung PTV, cardiac structures, liver, and thyroid were analyzed and compared. Results: CS-IMRT had 4 significant advantages over S-RT: (1) superior cardiac protection (2) superior 4-dimensional lung planning target volume coverage, (3) superior dose uniformity in the lungs with fewer hot spots, and (4) significantly lower dose to the heart when flank RT is administered after WLI. Conclusions: The use of CS-IMRT and 4-dimensional treatment planning has the potential to improve tumor control rates and reduce cardiac toxicity in children receiving WLI.

    Full Text Available Genetic variants within the endothelin-1 gene (EDN1 have been associated with several cardiovascular diseases and may act as genetic prognostic markers. Here, we explored the overall relevance of EDN1 polymorphisms for long-term survival in patients undergoing on-pump cardiac surgery. A prospectively collected cohort of 455 Caucasian patients who underwent cardiac surgery with cardiopulmonary bypass was followed up for 5 years. The obtained genotypes and inferred haplotypes were analyzed for their associations with the five-year mortality rate (primary endpoint. The EDN1 T-1370G and K198N genotype distributions did not deviate from Hardy-Weinberg equilibrium and the major allele frequencies were 83% and 77%, respectively. The cardiovascular risk factors were equally distributed in terms of the different genotypes and haplotypes associated with the two polymorphisms. The five-year mortality rate did not differ among the different EDN1 T-1370G and K198N genotypes and haplotypes. Haplotype analysis revealed that carriers of the G-T (compound EDN1 T-1370G G/K198N T haplotype had a higher cardiac index than did non-carriers (p = 0.0008; however, this difference did not reach significance after adjusting for multiple testing. The results indicate that common variations in EDN1 do not act as prognostic markers for long-term survival in patients undergoing on-pump cardiac surgery.

    Full Text Available Background and objectives: In children undergoing congenital heart surgery, plasma brain natriuretic peptide levels may have a role in development of low cardiac output syndrome that is defined as a combination of clinical findings and interventions to augment cardiac output in children with pulmonary hypertension. Methods: In a prospective observational study, fifty-one children undergoing congenital heart surgery with preoperative echocardiographic study showing pulmonary hypertension were enrolled. The plasma brain natriuretic peptide levels were collected before operation, 12, 24 and 48 h after operation. The patients enrolled into the study were divided into two groups depending on: (1 Development of LCOS which is defined as a combination of clinical findings or interventions to augment cardiac output postoperatively; (2 Determination of preoperative brain natriuretic peptide cut-off value by receiver operating curve analysis for low cardiac output syndrome. The secondary end points were: (1 duration of mechanical ventilation ≥72 h, (2 intensive care unit stay >7days, and (3 mortality. Results: The differences in preoperative and postoperative brain natriuretic peptide levels of patients with or without low cardiac output syndrome (n = 35, n = 16, respectively showed significant differences in repeated measurement time points (p = 0.0001. The preoperative brain natriuretic peptide cut-off value of 125.5 pg mL−1 was found to have the highest sensitivity of 88.9% and specificity of 96.9% in predicting low cardiac output syndrome in patients with pulmonary hypertension. A good correlation was found between preoperative plasma brain natriuretic peptide level and duration of mechanical ventilation (r = 0.67, p = 0.0001. Conclusions: In patients with pulmonary hypertension undergoing congenital heart surgery, 91% of patients with preoperative plasma brain natriuretic peptide levels above 125.5 pg mL−1 are at risk of developing low cardiac

    Full Text Available Background: The identification of biomarkers for predicting morbidity and mortality, particularly in pediatric population undergoing cardiac surgery will contribute toward improving the patient outcome. There is an increasing body of literature establishing the clinical utility of hyperlactatemia and lactate clearance as prognostic indicator in adult cardiac surgical patients. However, the relationship between lactate clearance and mortality risk in the pediatric population remains to be established. Objective: To assess the role of lactate clearance in determining the outcome in children undergoing corrective surgery for tetralogy of Fallot (TOF. Methods and Study Design: A prospective, observational study. Setting: A tertiary care center. Study Population: Two hundred children undergoing elective surgery for TOF. Study Method: Blood lactate levels were obtained as baseline before operation (T0, postoperatively at admission to the cardiac intensive care unit after surgery (T1, and then at every 6 h for the first 24 h of Intensive Care Unit (ICU stay (T6, T12, T18, and T24, respectively. The lactate clearance in the study is defined by the equation ([lactate initial - lactate delayed]/lactate initial ×100%. Lactate clearance was determined at T1-T6, T1-T12, T1-T18, and T1-T24 time interval, respectively. The primary outcome measured was mortality. Secondary outcomes measured were the duration of mechanical ventilation, duration of inotropic requirement, and duration of ICU stay. Results: Eleven out of the two hundred patients enrolled in the study died. Nonsurvivors had higher postoperative lactate concentration (P 10%, relative to patients with a lactate clearance 10% after 6 h have improved outcome compared with those with lower lactate clearance.

    Fetal and pediatric cardiac autopsies have a crucial role in the counseling of parents with regard to both the cause of death of their child and the implications of such findings for future pregnancies, as well as for quality assurance of antenatal screening programs and antemortem diagnostic procedures. Postmortem imaging allows an opportunity to investigate the heart in situ prior to dissection, and both postmortem CT and postmortem MRI have shown excellent accuracy in detecting the majority of clinically significant cardiac lesions in the perinatal and pediatric population. As less-invasive autopsy becomes increasingly popular, clinical guidelines for maximal diagnostic yield in specific circumstances can be developed. (orig.)

    The cardiac status of 64 children (ages 0.2 to 18 yr) with sickle cell anemia documented by hemoglobin electrophoresis was evaluated by echocardiography. Left atrial, left ventricular and aortic root dimensions were significantly increased in over 60 percent of these children at all ages compared to values for 99 normal black (non-SCA) control subjects. Left ventricular wall thickness was increased in only 20 percent of older children with sickle cell anemia. Estimated LV mass/m2 and left ventricular cardiac index were increased compared to control subjects (p less than 0.001). Left heart abnormalities expressed as a single composite function, derived from multivariate regression analysis, correlated well with severity of anemia expressed as grams of hemoglobin (r = -0.52, p = less than 0.001) and with percentage of hemoglobin S (r = 0.51, p less than 0.001), but not to the same extent with age. Echocardiographically assessed left ventricular function at rest was comparable to that of control subjects. These data suggest that the major cardiac abnormalities in children are related to the volume overload effects of chronic anemia, and that in this age group, there is no evidence for a distinct "sickle cell cardiomyopathy" or cardiac dysfunction.

    The hierarchical interaction between electrical signals of the brain and heart is not fully understood. We hypothesized that the complexity of cardiac electrical activity can be used to predict changes in encephalic electricity after stress. Most methods for analyzing the interaction between the heart rate variability (HRV) and electroencephalography (EEG) require a computation-intensive mathematical model. To overcome these limitations and increase the predictive accuracy of human relaxing states, we developed a method to test our hypothesis. In addition to routine linear analysis, multiscale entropy and detrended fluctuation analysis of the HRV were used to quantify nonstationary and nonlinear dynamic changes in the heart rate time series. Short-time Fourier transform was applied to quantify the power of EEG. The clinical, HRV, and EEG parameters of postcatheterization EEG alpha waves were analyzed using change-score analysis and generalized additive models. In conclusion, the complexity of cardiac electrical signals can be used to predict EEG changes after stress.

    Background: Most congenital heart diseases (CHDs) have specific hemodynamics, including volume and pressure overload, as well as cyanosis and pulmonary hypertension, associated with anatomical abnormalities. Such hemodynamic abnormalities can cause activation of neurohormones, inflammatory cytokines, fibroblasts, and vascular endothelial cells, which in turn contribute to the development of pathologic conditions such as cardiac hypertrophy,fi brosis, and cardiac cell damages and death. Measuring biomarker levels facilitates the prediction of these pathological changes, and provides information about the stress placed on the myocardial cells, the severity of the damage, the responses of neurohumoral factors, and the remodeling of the ventricle. Compared to the ample information on cardiac biomarkers in adult heart diseases, data from children with CHD are still limited. Data sources: We reviewed cardiac biomarkers-specifi cally focusing on troponin as a biomarker of myocardial damage, amino-terminal procollagen type III peptide (PIIIP) as a biomarker of myocardialfi brosis and stromal remodeling, and B-type natriuretic peptide (BNP)/N-terminal proBNP as biomarkers of cardiac load and heart failure, by introducing relevant publications, including our own, on pediatric CHD patients as well as adults. Results: Levels of highly sensitive troponin I are elevated in patients with atrial septal defects (ASDs) and ventricular septal defects (VSDs). PIIIP levels are also elevated in patients with ASD, VSD, pulmonary stenosis, and Tetralogy of Fallot. Measurement of BNP and N-terminal proBNP levels shows good correlation with heart failure score in children. Conclusions: In the treatment of children with CHD requiring delicate care, it is vital to know the specifi c degree of myocardial damage and severity of heart failure. Cardiac biomarkers are useful tools for ascertaining the condition of CHDs with ease and are likely to be useful in determining the appropriate care of

    Full Text Available Antifibrinolytic agents are used during cardiac surgery to minimize bleeding and reduce exposure to blood products. Several reports suggest that tranexamic acid (TA can induce seizure activity in the postoperative period. To examine factors associated with postoperative seizures in patients undergoing cardiac surgery who received TA. University-affiliated hospital. Case-control study. Patients undergoing cardiac surgery with cardiopulmonary bypass (CPB between January 2008 and December 2009 were identified. During this time, all patients undergoing heart surgery with CPB received TA. Cases were defined as patients who developed seizures that required initiation of anticonvulsive therapy within 48 h of surgery. Exclusion criteria included subjects with preexisting epilepsy and patients in whom the convulsive episode was secondary to a new ischemic lesion on brain imaging. Controls who did not develop seizures were randomly selected from the initial cohort. From an initial cohort of 903 patients, we identified 32 patients with postoperative seizures. Four patients were excluded. Twenty-eight cases and 112 controls were analyzed. Cases were more likely to have a history of renal impairment and higher preoperative creatinine values compared with controls (1.39 ± 1.1 vs. 0.98 ± 0.02 mg/dL, P = 0.02. Significant differences in the intensive care unit, postoperative and total lengths of stay were observed. An association between high preoperative creatinine value and postoperative seizure was identified. TA may be associated with the development of postoperative seizures in patients with renal dysfunction. Doses of TA should be reduced or even avoided in this population.

    The postoperative low cardiac output is one of the most important complications following cardiac surgery and is associated with increased morbidity and mortality. The condition requires inotropic support to achieve adequate hemodynamic status and tissue perfusion. While catecholamines are utilised as a standard therapy in cardiac surgery, their use is limited due to increased oxygen consumption. Levosimendan is calcium sensitising inodilatator expressing positive inotropic effect by binding with cardiac troponin C without increasing oxygen demand. Furthermore, the drug opens potassium ATP (KATP) channels in cardiac mitochondria and in the vascular muscle cells, showing cardioprotective and vasodilator properties, respectively. In the past decade, levosimendan demonstrated promising results in treating patients with reduced left ventricular function when administered in peri- or post- operative settings. In addition, pre-operative use of levosimendan in patients with severely reduced left ventricular ejection fraction may reduce the requirements for postoperative inotropic support, mechanical support, duration of intensive care unit stay as well as hospital stay and a decrease in post-operative mortality. However, larger studies are needed to clarify clinical advantages of levosimendan versus conventional inotropes.

    Raquel A Sirvente

    Full Text Available BACKGROUND: Sympathetic hyperactivity may be related to left ventricular (LV dysfunction and baro- and chemoreflex impairment in hypertension. However, cardiac function, regarding the association of hypertension and baroreflex dysfunction, has not been previously evaluated by transesophageal echocardiography (TEE using intracardiac echocardiographic catheter. METHODS AND RESULTS: We evaluated exercise tests, baroreflex sensitivity and cardiovascular autonomic control, cardiac function, and biventricular invasive pressures in rats 10 weeks after sinoaortic denervation (SAD. The rats (n = 32 were divided into 4 groups: 16 Wistar (W with (n = 8 or without SAD (n = 8 and 16 spontaneously hypertensive rats (SHR with (n = 8 or without SAD (SHRSAD (n = 8. Blood pressure (BP and heart rate (HR did not change between the groups with or without SAD; however, compared to W, SHR groups had higher BP levels and BP variability was increased. Exercise testing showed that SHR had better functional capacity compared to SAD and SHRSAD. Echocardiography showed left ventricular (LV concentric hypertrophy; segmental systolic and diastolic biventricular dysfunction; indirect signals of pulmonary arterial hypertension, mostly evident in SHRSAD. The end-diastolic right ventricular (RV pressure increased in all groups compared to W, and the end-diastolic LV pressure increased in SHR and SHRSAD groups compared to W, and in SHRSAD compared to SAD. CONCLUSIONS: Our results suggest that baroreflex dysfunction impairs cardiac function, and increases pulmonary artery pressure, supporting a role for baroreflex dysfunction in the pathogenesis of hypertensive cardiac disease. Moreover, TEE is a useful and feasible noninvasive technique that allows the assessment of cardiac function, particularly RV indices in this model of cardiac disease.

    The effect of heparin on blood clotting was studied by measuring the activated clotting time (ACT) in 120 infants and children with congenital heart disease after a single intravenous bolus of 100 IU heparin/kg body weight. Before heparinization, infants and children with cyanotic heart disease showed signs of hypocoagulation. Heparin bolus led to a threefold increase of ACT after 15 min. After 1 h, the ACT was still two times the normal value. Any further administration of heparin may be based on ACT monitoring.

    Although the centrifugal pump has been widely used as a nonpulsatile pump for cardiopulmonary bypass (CPB), little is known about its performance as a pulsatile pump for CPB, especially on its efficacy in producing hemodynamic energy and its clinical effectiveness. We performed a study to evaluate whether the Rotaflow centrifugal pump produces effective pulsatile flow during CPB and whether the pulsatile flow in this setting is clinically effective in adult patients undergoing cardiac surgery. Thirty-two patients undergoing CPB for elective coronary artery bypass grafting were randomly allocated to a pulsatile perfusion group (n = 16) or a nonpulsatile perfusion group (n = 16). All patients were perfused with the Rotaflow centrifugal pump. In the pulsatile group, the centrifugal pump was adjusted to the pulsatile mode (60 cycles/min) during aortic cross-clamping, whereas in the nonpulsatile group, the pump was kept in its nonpulsatile mode during the same period of time. Compared with the nonpulsatile group, the pulsatile group had a higher pulse pressure (P centrifugal pump is associated with a small gain of EEP and SHE, which does not seem to be clinically effective in adult cardiac surgical patients.

    The tolerability of a 2.5% lidocaine/prilocaine hydrogel (Nanorap, Biolab Indústria Farmacêutica Ltd., Sao Paulo, Brazil) was evaluated in 20 children ages 2 to 11 years undergoing cryotherapy for molluscum contagiosum (MC). The product was well tolerated, with only two children presenting with eczema at the application site. These adverse reactions were considered unlikely to be related to the test product, because a patch test was negative in one of the individuals and the other event occurred in only one of the two treated areas. Nanorap is an efficacious and well-tolerated option for topical anesthesia in children undergoing cryotherapy for MC. PMID:27041686

    We report the case of successful resuscitation after prolonged cardiac arrest during orthotopic liver transplantation. After reperfusion, the patient developed ventricular tachycardia, complicated by intracardiac clot formation and massive hemorrhage. Transesophageal echocardiography demonstrated stunned and nonfunctioning right and left ventricles, with developing intracardiac clots. Treatment with heparin, massive transfusion and prolonged cardiopulmonary resuscitation ensued for 51 minutes. Serial arterial blood gases demonstrated adequate oxygenation and ventilation during cardiopulmonary resuscitation. Cardiothoracic surgery was consulted for potential use of extracorporeal membrane oxygenation, however, the myocardial function improved and the surgery was completed without further intervention. On postoperative day 6, the patient was extubated without neurologic or cardiac impairment. The patient continues to do well 2 years posttransplant, able to perform independent daily activities of living and his previous job. This case underscores the potential for positive outcomes with profoundly prolonged, effective advanced cardiovascular life support in patients who experience postreperfusion syndrome. PMID:27233818

    Pineal cysts, both simple and complex, are commonly encountered in children. More cysts are being detected with MR technology; however, nearly all pineal cysts are benign and require no follow-up. To discover the prevalence of pineal cysts in children at our institution who have undergone high-resolution 3-T MRI. We retrospectively reviewed 100 consecutive 3-T brain MRIs in children ages 1 month to 17 years (mean 6.8 {+-} 5.1 years). We evaluated 3-D volumetric T1-W imaging, axial T2-W imaging, axial T2-W FLAIR (fluid attenuated inversion recovery) and coronal STIR (short tau inversion recovery) sequences. Pineal parenchymal and cyst volumes were measured in three planes. Cysts were analyzed for the presence and degree of complexity. Pineal cysts were present in 57% of children, with a mean maximum linear dimension of 4.2 mm (range 1.5-16 mm). Of these cysts, 24.6% showed thin septations or fluid levels reflecting complexity. None of the cysts demonstrated complete T2/FLAIR signal suppression. No cyst wall thickening or nodularity was present. There was no significant difference between the ages of children with and without cysts. Cysts were more commonly encountered in girls than boys (67% vs. 52%; P = 0.043). There was a slight trend toward increasing pineal gland volume with age. Pineal cysts are often present in children and can be incidentally detected by 3-T MRI. Characteristic-appearing pineal cysts in children are benign, incidental findings, for which follow-up is not required if there are no referable symptoms or excessive size. (orig.)

    Ever since percutaneous endoscopic gastronomy (PEG) was used for the first time in 1980 by Gauderer, Ponsky, Izant et al., It has been widely used in patients incapable of oral feeding. It is a safe and effective technique for long-term nutritional support in children, and easy to perform, as only local anesthesia or heavy sedation is required PEG can prevent children from suffering from nasopharyngeal and esophageal erosions due to repeated insertion of nasogastric tubes and the complication of aspiration pneumonia. It is therefore an alternative for children who need long-term feeding. In this article we review the literature on PEG and give a full description of its indications, complications, as well as advice on when to change gastrostomy tubes, and on nursing care, in the hope that this will be useful reference material for medical staff.

    Sickle cell anaemia (SCA) is one of the commonest chronic hemolytic anaemias in the Sudan; it is a disease with high mortality and morbidity. This study was conducted aiming to observe the clinical pattern of cardiac abnormalities in children with sickle cell anaemia, and to assess the relationship between the cardiac abnormalities and the severity of the disease. The study was conducted in sickle cell disease clinic at Khartoum Children Emergency Hospital. The study group consisted of 289 patients with sickle cell anaemia, age range from 6 months to 18 years. Data were collected using a questionnaire which include full history, clinical examination findings, chest x-rays, and Electro-cardiography. Tachycardia, systolic murmurs, and cardiomegaly were detected in 28%, 61%, and 54% of patients with SCA respectively. Left ventricular dilatation was observed in 51% of the study group, while right ventricular dilatation was observed in 22% of the patients. Left and right atrial dilatations were observed in 16% and 6% of the patients respectively. Contractility, ejection fraction (EF) were found almost always normal in all study subjects. Chamber dilatations were not associated with any abnormality in Left ventricular functions. Hemglobin (Hb) levels correlated negatively with cardiomegaly. Left Ventricular End Diastolic Dimension (LVEDD) correlates negatively with Hb levels and positively with the severity index. Only four patients (1%) had abnormal valves. In conclusion, cardiac abnormalities in patients with SCA correlate with the age of the patients and the severity of the disease. PMID:27493331

    The close relationship between patent foramen ovale(PFO)and cryptogenic ischemic cerebrovascular disease and migraine has been concerned for years. However,in the field of non-cardiac surgery and anesthesiology, PFO and related clinical problems are less recognized. Under perioperative circumstances,PFO may generate many challenges such as paradoxical systematic embolism and severe hypoxemia. This article briefly introduces the epidemiology, paradoxical embolism, and detection methods of PFO and discribes the perioperative complications and corresponding perioperative strategies for prevention and cure.

    Full Text Available Bedside emergency ultrasound has rapidly developed over the past several years and has now become part of the standard of care for several applications. While it has only recently been applied to critically ill pediatric patients, several of the well-established adult indications may be applied to pediatric patients. One of the most important and life-saving applications is bedside echocardiography. While bedside emergency ultrasonography does not serve to replace formal comprehensive studies, it serves as an extension of the physical examination. It is especially useful as a rapid and effective tool in the diagnosis of pericardial effusions, tamponade and in distinguishing potentially reversible causes of pulseless electrical activity from asystole. Most recently, left ventricular function and inferior vena cava measurements have proven helpful in the assessment of undifferentiated hypotension and shock in adults and children. Future research remains to be carried out in determining the efficacy of bedside ultrasonography in pediatric-specific pathology such as congenital heart disease. This article serves as a comprehensive review of the adult literature and a review of the recent applications in the pediatric emergency department. It also highlights the techniques of bedside ultrasonography with examples of normal and pathologic images.

    MRI is an important additional tool in the diagnostic work-up of children with congenital heart disease. This review aims to summarise the role MRI has in this patient population. Echocardiography remains the main diagnostic tool in congenital heart disease. In specific situations, MRI is used for anatomical imaging of congenital heart disease. This includes detailed assessment of intracardiac anatomy with 2-D and 3-D sequences. MRI is particularly useful for assessment of retrosternal structures in the heart and for imaging large vessel anatomy. Functional assessment includes assessment of ventricular function using 2-D cine techniques. Of particular interest in congenital heart disease is assessment of right and single ventricular function. Two-dimensional and newer 3-D techniques to quantify flow in these patients are or will soon become an integral part of quantification of shunt size, valve function and complex flow patterns in large vessels. More advanced uses of MRI include imaging of cardiovascular function during stress and tissue characterisation of the myocardium. Techniques used for this purpose need further validation before they can become part of the daily routine of MRI assessment of congenital heart disease. (orig.)

    This qualitative study examined the subjective experience of children undergoing an invasive examination in the hospital when accompanied by a medical clown. In-depth semi-structured interviews were conducted with nine such children and nine of their accompanying parents. The children were patients in two outpatient departments (Pediatric Gastroenterology and a Center for the Sexually Abused) in a hospital in Israel. Interviews were coded thematically using an Atlas.ti software program. Analysis of the interviews indicated that the intervention of the clown positively changed the children's perceptions of the hospital, of experiencing the examination, and of their life narrative. Medical clowns thus appear to be a central, meaningful, and therapeutic source for children undergoing invasive examinations in hospital, as well as for their parents. Therefore, it may be advisable to incorporate medical clowns as an integral part of medical teams performing invasive procedures and to include the clowns in all stages of the hospital visit.

    Although single individual reports have documented outcomes in children with pentalogy of are few data available for postoperative outcome of this cohort of patients after cardiac surgery. The aim of this study was to retrospectively review the clinical details of patients with pentalogy of Cantrell managed at two centers. Two cardiac surgical institutions retrospectively studied all patients with pentalogy of Cantrell and significant congenital heart disease who underwent surgical intervention, excluding PDA ligation, between 1992 and 2004. Seven children with pentalogy of Cantrell underwent surgical intervention at a median age of 60 days (range, 1-11 months). Three patients had tetralogy of Fallot, two double outlet right ventricle, one patient had tricuspid atresia, and one patient a perimembranous ventricular septal defect. The mean duration of postoperative ventilation was 112.8 days (range, 4-335 days) but three patients required ventilation for more than 100 days. Patients who had a preoperative diaphragmatic plication required a longer duration of ventilation (mean = 186.5 days [range, 100-273 days] compared with mean = 132 days [range, 4-335 days]). Four patients survived, with three patients weaned from ventilation. Three patients had withdrawal of care following failure to wean from ventilation, following multisystem organ failure, and at the request of their parents. In conclusion, the postoperative care of children with pentalogy of Cantrell after cardiac surgery is often complicated by prolonged need for ventilatory support and multiple postoperative complications. Earlier surgical intervention does not necessarily reduce morbidity and mortality. These data may help in the counseling of parents prior to surgical intervention.

    Full Text Available Abstract Background Preoperative anxiety and physical unfitness have been shown to have adverse effects on recovery from cardiac surgery. This study involving cardiac surgery patients was primarily aimed at assessing the feasibility of delivering physical conditioning and stress reduction programs within the public hospital setting. Secondary aims were to evaluate the effect of these programs on quality of life (QOL, rates of postoperative atrial fibrillation (AF and length of stay (LOS in hospital. Methods Elective patients scheduled for coronary artery bypass graft and/or valve surgery at a public hospital in Melbourne, Australia were enrolled. Patients were randomized to receive either holistic therapy (HT or usual care (UC. HT consisted of a series of light physical exercise sessions together with a mental stress reduction program administered in an outpatient setting for the first two weeks after placement on the waiting list for surgery. A self-administered SF-36 questionnaire was used to measure QOL and hospital records to collect data on LOS and rate of postoperative AF. Results The study population comprised 117 patients of whom 60 received HT and 57 received UC. Both programs were able to be delivered within the hospital setting but ongoing therapy beyond the two week duration of the program was not carried out due to long waiting periods and insufficient resources. HT, as delivered in this study, compared to UC did not result in significant changes in QOL, LOS or AF incidence. Conclusions Preoperative holistic therapy can be delivered in the hospital setting, although two weeks is insufficient to provide benefits beyond usual care on QOL, LOS or postoperative AF. Further research is now required to determine whether a similar program of longer duration, or targeted to high risk patients can provide measurable benefits. Trial registration This trial was conducted as part of a larger study and according to the principles contained in

    INTRODUCTION: It is thought that patients with cardiomyopathy have an increased risk of cardiac arrest on induction of anesthesia, but there is little available data. The purpose of this study was to identify the incidence and potential risk factors for cardiac arrest upon induction of anesthesia in children with cardiomyopathy in our institution. METHODS: A retrospective chart review was performed. Eligible patients included patients admitted between 1998 and 2008 with the International Statistical Classification of Disease code for cardiomyopathy (ICD-9 code 425) who underwent airway intervention for sedation or general anesthesia in the operating room, cardiac diagnostic and interventional unit (CDIU) or intensive care unit. Patients undergoing emergency airway intervention following cardiovascular collapse were excluded. For each patient, we recorded patient demographics, disease severity, anesthesia location, and anesthetic technique. RESULTS: One hundred and twenty-nine patients with cardiomyopathy underwent a total of 236 anesthetic events, and four cardiac arrests were identified. One was related to bradycardia (HR<60), two were attributed to bradycardia in association with severe hypotension (systolic blood pressure<45), and the fourth arrest was related to isolated severe hypotension. Two occurred in the operating suite and two in the CDIU. There was no resulting mortality. One patient progressed to heart transplantation. Multiple combinations of anesthetic drugs were used for induction of anesthesia. CONCLUSION: We performed a review of the last 10 years of anesthesia events in children with cardiomyopathy. We report four cardiac arrests in two patients and 236 anesthetic events (1.7%). To the best of our knowledge, this is the largest review of these patients to date but is limited by its retrospective nature. The low cardiac arrest incidence prevents the identification of risk factors and the development of a cardiac arrest risk predictive clinical

  7. Renal function interferes with copeptin in prediction of major adverse cardiac events in patients undergoing vascular surgery.

    Full Text Available Precise perioperative risk stratification is important in vascular surgery patients who are at high risk for major adverse cardiovascular events (MACE peri- and postoperatively. In clinical practice, the patient's perioperative risk is predicted by various indicators, e.g. revised cardiac index (RCRI or modifications thereof. Patients suffering from chronic kidney disease (CKD are stratified into a higher risk category. We hypothesized that Copeptin as a novel biomarker for hemodynamic stress could help to improve the prediction of perioperative cardiovascular events in patients undergoing vascular surgery including patients with chronic kidney disease.477 consecutive patients undergoing abdominal aortic, peripheral arterial or carotid surgery from June 2007 to October 2012 were prospectively enrolled. Primary endpoint was 30-day postoperative major adverse cardiovascular events (MACE.41 patients reached the primary endpoint, including 63.4% aortic, 26.8% carotid, and 9.8% peripheral surgeries. Linear regression analysis showed that RCRI (P< .001, pre- (P< .001, postoperative Copeptin (P< .001 and Copeptin level change (P= .001 were associated with perioperative MACE, but CKD remained independently associated with MACE and Copeptin levels. Multivariate regression showed that increased Copeptin levels added risk predictive information to the RCRI (P= .003. Especially in the intermediate RCRI categories was Copeptin significantly associated with the occurrence of MACE. (P< .05 Kruskal Wallis test. Subdivision of the study cohort into CKD stages revealed that preoperative Copeptin was significantly associated with CKD stages (P< .0001 and preoperative Copeptin measurements could not predict MACE in patients with more severe CKD stages.Preoperative Copeptin loses its risk predictive potential for perioperative MACE in patients with chronic kidney disease undergoing vascular surgery.

    Background Cardiac surgery for congenital heart disease covers a wide spectrum from simple to complex cardiac and extracardiac malformations.Innovations in pediatric cardiac surgery and perioperative care over the past decades have allowed surgical correction or at least palliation in almost all complex congenital heart defects in the first years of life.Diaphragmatic paralysis (DP) due to phrenic nerve injury after congenital cardiac surgery is an important respiratory complication resulting with respiratory insufficiency,lung infections,prolonged hospital stay time and even death.Methods Between April 2001 and December 2010,among patients undergoing cardiac surgery for congenital heart disease,postoperative DP was diagnosed in 47/10 200 (0.46%) patients.Diaphragmatic placation was performed in 37/47 patients.DP was suspected in children who failed to wean from mechanical ventilation or in those with persistent respiratory distress when there is no cardiac cause.Decreased respiratory sounds in auscultation,paradoxical breathing during spontaneous ventilation and elevated hemidiaphragm on chest X-ray led us to use fluoroscopy,ultrasound and/or electromyogram (EMG).When chest X-rays did not have a diagnostic value in patients with persistent respiratory distress,bilateral DP was suspected and immediate fluoroscopy of EMG was performed for diagnosis.In all patients,diaphragmatic placation was performed using a thoracic approach,through the sixth or seventh intercostals space with lateral thoracotomy.Results A total of 47 patients (21 females and 26 males) with a median age of 7.21 months (range 0.27-71 months) were diagnosed DP after cardiac surgery.The incidence of DP was 0.46% after cardiac surgery.The paralysed hemidiaphragm was left side in 26/47 (55.3%),right side in 17/47 (36.2%) and bilateral in 4/47 (8.5%) cases.The assisted ventilation time after cardiac surgery was (450±216) (116-856) hours.The median time from cardiac surgery to surgical

  9. A dosimetric study during cardiac angiography in young children

    International Nuclear Information System (INIS)

    A dosimetric study was carried out in collaboration with the SCPRI in 30 infants during cardiac catheterization for a congenital cardiopathy. As far as the doctor is concerned, the results show that the dose received by the right hand of the operator is the only one that is relatively high and notably higher than in the adult; the other results are in agreement with those published in the literature. For the manipulator the doses received are practically negligible. This finding does not agree with those of certain publications in the literature and it emphasizes the importance of the working conditions for these personnel. For infants, the gonadal dose is much higher than in the adult and the magnitude of the dose relative to the dose at the place of entry of the incident beam, taking into account the weight of the infant, certaintly represents a long-term risk, in particular, in patients who must undergo repeated examinations

    Full Text Available Introduction. While patients undergoing orthotopic liver transplantation (OLT have high cardiovascular event rates, preoperative risk stratification may not necessarily predict those susceptible patients. Troponin T (TnT may help predict patients at risk for cardiovascular complications. Methods. Consecutive patients undergoing OLT at Mayo Clinic in Florida between 1998 and 2010 who had TnT obtained within 10 days following surgery were included. Three groups were compared based on TnT level: (1 normal (TnT ≤0.01 ng/mL, (2 intermediate (TnT 0.02–0.11 ng/mL, and (3 elevated (TnT >0.11 ng/mL. Overall and cardiovascular mortality was assessed. Results. Of the 78 patients included, there was no difference in age, gender, severity of liver disease, and echocardiographic findings. Patients in the normal and intermediate TnT groups had a lower overall mortality rate (14.3% and 0%, resp. when compared with those with elevated TnT (50%; P=0.001. Patients in the elevated TnT group had a cardiovascular mortality rate of 37.5% compared with 1.4% in the other groups combined (P<0.01. The elevated TnT group had a much higher mortality rate when compared with those in the intermediate group (P<0.0001. Conclusion. TnT may accurately help risk stratify patients in the early postoperative setting to better predict cardiovascular complications.

    Full Text Available Objective: Cardiac surgery is an important event an individual’s life and can cause the collapse of the economic, personal, and professional life of the person and impair their physical functioning. Fear, anxiety, depression, and other mental health problems may be experienced by the operated patient. Assessment of the causes of anxiety and stress requires the awareness of nurses and patients of these factors which differ from each other. The aim of this review study was to examine nurses' views regarding stressors of coronary artery bypass surgery. Materials and Methods: This research was a review study and was conducted by reviewing the literature related to this topic and also visiting the Cumulative Index to Nursing and Allied Health Literature (CINAHL, PubMed, and other authentic websites. Results: It is better that nurses and patients have an open relationship at any given time and nurses encourage the patients to speak about their anxiety. Evaluating patients’ perception of fear and anxiety may help identify patients at risk of substantial psychological stress. Conclusion: According to previous studies, in general, the assessment of individuals should be one of the goals of nursing care so that appropriate trainings can be provided according to the needs of patients and patients can be assisted in coping with stressors.

    Anticoagulation of patients with cardiac tamponade (CT) complicating catheter ablation of atrial fibrillation (AF) is an ongoing problem. The aim of this study was to survey the clinical practice of periprocedural anticoagulation in such patients. This study analyzed the periprocedural anticoagulation of 17 patients with CT complicating AF ablation. Emergent pericardiocentesis was performed once CT was confirmed. The mean drained volume was 410.0 ± 194.1 mL. Protamine sulfate was administered to neutralize heparin (1 mg neutralizes 100 units heparin) in 11 patients with persistent pericardial bleeding and vitamin K1 (10 mg) was given to reverse warfarin in 3 patients with supratherapeutic INR (INR > 2.1). Drainage catheters were removed 12 hours after echocardiography confirmed absence of intrapericardial bleeding and anticoagulation therapy was restored 12 hours after removing the catheter. Fifteen patients took oral warfarin and 10 of them were given subcutaneous injection of LMWH (1 mg/kg, twice daily) as a bridge to resumption of systemic anticoagulation with warfarin. Two patients with a small amount of persistent pericardial effusion were given LMWH on days 5 and 13, and warfarin on days 6 and 24. The dosage of warfarin was adjusted to keep the INR within 2-3 in all patients. After 12 months of follow-up, all patients had no neurological events and no occurrence of delayed CT. The results showed that it was effective and safe to resume anticoagulation therapy 12 hours after removal of the drainage catheter. This may help to prevent thromboembolic events following catheter ablation of AF. PMID:25503659

    Hypoxemia is a frequent complication after coronary artery bypass graft (CABG) with cardiopulmonary bypass (CPB), usually attributed to atelectasis. Using computed tomography (CT), we investigated postoperative pulmonary alterations and their impact on blood oxygenation. Eighteen non-hypoxemic patients (15 men and 3 women) with normal cardiac function scheduled for CABG under CPB were studied. Hemodynamic measurements and blood samples were obtained before surgery, after intubation, after CPB, at admission to the intensive care unit, and 12, 24, and 48 h after surgery. Pre- and postoperative volumetric thoracic CT scans were acquired under apnea conditions after a spontaneous expiration. Data were analyzed by the paired Student t-test and one-way repeated measures analysis of variance. Mean age was 63 {+-} 9 years. The PaO{sub 2}/FiO{sub 2} ratio was significantly reduced after anesthesia induction, reaching its nadir after CPB and partially improving 12 h after surgery. Compared to preoperative CT, there was a 31% postoperative reduction in pulmonary gas volume (P < 0.001) while tissue volume increased by 19% (P < 0.001). Non-aerated lung increased by 253 {+-} 97 g (P < 0.001), from 3 to 27%, after surgery and poorly aerated lung by 72 {+-} 68 g (P < 0.001), from 24 to 27%, while normally aerated lung was reduced by 147 {+-} 119 g (P < 0.001), from 72 to 46%. No correlations (Pearson) were observed between PaO{sub 2}/FiO{sub 2} ratio or shunt fraction at 24 h postoperatively and postoperative lung alterations. The data show that lung structure is profoundly modified after CABG with CPB. Taken together, multiple changes occurring in the lungs contribute to postoperative hypoxemia rather than atelectasis alone. (author)

    Objectives of the Study: To identify the factors causing high lactate levels in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB) and to assess the association between high blood lactate levels and postoperative morbidity and mortality. Methods: A retrospective observational study including 370 patients who underwent cardiac surgeries under cardiopulmonary bypass. The patients were divided into 2 groups based on serum lactate levels; those with serum lactate levels greater than or equal to 4 mmol/L considered as hyperlactatemia and those with serum lactate levels less than 4 mmol/L. Blood lactate samples were collected intraoperatively and postoperatively in the ICU. Preoperative and intraoperative risk factors for hyperlactatemia were identified using the highest intraoperative value of lactate. The postoperative morbidity and mortality associated with hyperlactatemia was studied using the overall (intraoperative and postoperative values) peak lactate levels. Preoperative clinical data, perioperative events and postoperative morbidity and mortality were recorded. Results: Intraoperative peak blood lactate levels of 4.0 mmol/L or more were present in 158 patients (42.7%). Females had higher peak intra operative lactate levels (P = 0.011). There was significant correlation between CPB time (Pearson correlation coefficient r = 0.024; P = 0.003) and aortic cross clamp time (r = 0.02, P = 0.007) with peak intraoperative blood lactate levels. Patients with hyperlactatemia had significantly higher rate of postoperative morbidity like atrial fibrillation (19.9% vs. 5.3%; P = 0.004), prolonged requirement of inotropes (34% vs. 11.8%; P = 0.001), longer stay in the ICU (P = 0.013) and hospital (P = 0.001). Conclusions: Hyperlactatemia had significant association with post-operative morbidity. Detection of hyperlactatemia in the perioperative period should be considered as an indicator of inadequate tissue oxygen delivery and must be aggressively

    The pharmacokinetics of propranolol may be altered by hypothermic cardiopulmonary bypass (CPB), resulting in unpredictable postoperative hemodynamic responses to usual doses. The objective of the present study was to investigate the pharmacokinetics of propranolol in patients undergoing coronary artery bypass grafting (CABG) by CPB under moderate hypothermia. We evaluated 11 patients, 4 women and 7 men (mean age 57 +/- 8 years, mean weight 75.4 +/- 11.9 kg and mean body surface area 1.83 +/- 0.19 m(2)), receiving propranolol before surgery (80-240 mg a day) and postoperatively (10 mg a day). Plasma propranolol levels were measured before and after CPB by high-performance liquid chromatography. Pharmacokinetic Solutions 2.0 software was used to estimate the pharmacokinetic parameters after administration of the drug pre- and postoperatively. There was an increase of biological half-life from 4.5 (95% CI = 3.9-6.9) to 10.6 h (95% CI = 8.2-14.7; P < 0.01) and an increase in volume of distribution from 4.9 (95% CI = 3.2-14.3) to 8.3 l/kg (95% CI = 6.5-32.1; P < 0.05), while total clearance remained unchanged 9.2 (95% CI = 7.7-24.6) vs 10.7 ml min(-1) kg(-1) (95% CI = 7.7-26.6; NS) after surgery. In conclusion, increases in drug distribution could be explained in part by hemodilution during CPB. On the other hand, the increase of biological half-life can be attributed to changes in hepatic metabolism induced by CPB under moderate hypothermia. These alterations in the pharmacokinetics of propranolol after CABG with hypothermic CPB might induce a greater myocardial depression in response to propranolol than would be expected with an equivalent dose during the postoperative period.

Currently, no methods exist to map visual analog scale (VAS scores to utility values. This study aimed to develop and propose a statistical algorithm for mapping five dimensions of health, measured on VASs, to utility scores in patients suffering from cardiovascular disease. Methods: Patients undergoing coronary artery bypass grafting at Aalborg University Hospital in Denmark were asked to score their health using the five VAS items (mobility, self-care, ability to perform usual activities, pain, and presence of anxiety or depression and the EuroQol 5 Dimensions questionnaire. Regression analysis was used to estimate four mapping models from patients' age, sex, and the self-reported VAS scores. Prediction errors were compared between mapping models and on subsets of the observed utility scores. Agreement between predicted and observed values was assessed using Bland–Altman plots. Results: Random effects generalized least squares (GLS regression yielded the best results when quadratic terms of VAS scores were included. Mapping models fitted using the Tobit model and censored least absolute deviation regression did not appear superior to GLS regression. The mapping models were able to explain approximately 63%–65% of the variation in the observed utility scores. The mean absolute error of predictions increased as the observed utility values decreased. Conclusion: We concluded that it was possible to predict utility scores from VAS scores of the five

    AIM: To review gastrointestinal and liver infections in children undergoing antineoplastic chemotherapy. To look at gut microflora features in oncology children. METHODS: We selected studies published after year 2000, excluding trials on transplanted pediatric patients. We searched English language publications in MEDLINE using the keywords: “gastrointestinal infection AND antineoplastic chemotherapy AND children”, “gastrointestinal infection AND oncology AND children”, “liver infection AND antineoplastic chemotherapy AND children”, “liver abscess AND chemotherapy AND child”, “neutropenic enterocolitis AND chemotherapy AND children”, “thyphlitis AND chemotherapy AND children”, “infectious diarrhea AND children AND oncology”, “abdominal pain AND infection AND children AND oncology”, “perianal sepsis AND children AND oncology”, “colonic pseudo-obstruction AND oncology AND child AND chemotherapy”, “microflora AND children AND malignancy”, “microbiota AND children AND malignancy”, “fungal flora AND children AND malignancy”. We also analysed evidence from several articles and book references. RESULTS: Gastrointestinal and liver infections represent a major cause of morbidity and mortality in children undergoing antineoplastic chemotherapy. Antineoplastic drugs cause immunosuppression in addition to direct toxicity, predisposing to infections, although the specific risk is variable according to disease and host features. Common pathogens potentially induce severe diseases whereas opportunistic microorganisms may attack vulnerable hosts. Clinical manifestations can be subtle and not specific. In addition, several conditions are rare and diagnostic process and treatments are not standardized. Diagnosis may be challenging, however early diagnosis is needed for quick and appropriate interventions. Interestingly, the source of infection in those children can be exogenous or endogenous. Indeed, mucosal damage may allow the

    Energy imbalance in infants and children with congenital heart disease (CHD) is common and influenced by age, underlying cardiac diagnoses, and presence or absence of congestive heart failure. During the surgical hospitalization period, these children are prone to nutritional deterioration due to stress of surgery, anesthetic/perfusion techniques, and postoperative care. Poor nutrition is associated with increased perioperative morbidity and mortality. This review aims to examine various aspects of nutrition in critically ill children with CHD, including (1) energy expenditure, (2) perioperative factors that contribute to energy metabolism, (3) bedside practices that are potentially able to optimize nutrient delivery, and (4) medium- to long-term impact of energy balance on clinical outcomes. We propose a nutrition algorithm to optimize nutrition of these children in the perioperative period where improvements in nutrition status will likely impact surgical outcomes.

    Full Text Available Bachground & aim: Pulse oximetry and cardiac catheterization are concerned in the treatment of children with congenital heart disease. Diagnosis of arterial oxygen saturation in patients with congenital heart disease (CHD can be used to assess and manage their effecacy. The purpose of this study was to compare pulse oximetry and cardiac catheterizations in treatment manage of children with congenital heart disease. Methods: In the present cross sectional study, 110 patients with cyanic and non syani heart disease were studied undergoing right and left heart catheterization by pulse oximetry of index finger and simultaneously, oxygen saturation was measured by cardiac catheterization. Data were analyzed with SPSS software by using Pearson correlation and linear regression. Results: A significant correlation was seen between arterial oxygen saturation measured by pulse oximetry and arterial oxygen saturation (p<0.0001 as well as heart rate, electrocardiogram and pulse oximetry (p<0.0001 respectively. Furthermore, the presence of cyanosis (p=0.001, digital clubbing of the fingers ((p=0.001, low oxygen saturation in the superior vena cava and right atrium (p=0.002 can reduce the accuracy of pulse oximetry for detection of arterial oxygen saturation. The mean right atrial pressure can effect on accuracy of pulse oximetry to detect heartbeat (p=0.034. Maximum sensitivity and specificity for detection of pulse oximetry oxygen saturation was 88 % and 88 heart rate per minute. Conclusion: Pulse oximetric is a useful tool for estimating the arterial oxygen saturation and heart rate in children with congenital heart disease (CHD and is a non-invasive method in comparison with cardiac catheterization.

    Full Text Available Background: Exercise and rehabilitation are important methods for decreasing the risk factors of coronary artery disease (CAD. We aimed to evaluate the effect of the cardiac rehabilitation (CR exercise program on the cardiac structure and physiology in patients undergoing percutaneous coronary intervention (PCI.Methods: In this randomized controlled study, 146 patients with CAD were divided equally into two groups: case group (undertaking CR after PCI and control group (without rehabilitation after PCI. All the patients in the case group underwent echocardiography (before and after CR, and echocardiography was performed for the control group simultaneously. The CR exercise program encompassed 24 sessions, twice or three times a week, with each session lasting between 15 and 45 minutes, depending on the individual patient’s tolerance. Left ventricular (LV ejection fraction, LV diastolic function, LV end-systolic and diastolic diameter, and right ventricular (RV end-diastolic diameter were measured in the CR group before and after rehabilitation and compared to those in the control group at the same times.Results: In this study, 146 patients (46 female and 100 male were evaluated: 73 in the rehabilitation group and 73 in the control group. The mean age of the patients in the CR and control groups was 58.05 ± 10.27 and 56.76 ± 10.07 years, respectively. The CR exercise program had useful effects on LV diastolic function after PCI. The distribution of LV diastolic dysfunction after the CR exercise program was changed significantly only in the CR group (p value = 0.043. In the CR group, normal, grade I, grade II, and grade III LV diastolic dysfunction were observed in 20.5%, 69.8%, 6.8%, and 2.7%, respectively. This distribution was changed respectively to 30.1%, 61.6%, 5.4%, and 2.7% following CR, which showed a significant improvement due to CR in LV diastolic function, most prominently in the patients with grade I diastolic dysfunction (p

    Full Text Available Background The role of the autonomic nervous system (ANS in the cardiovascular regulation is of primal importance. Since it has been associated with adverse conditions such as cardiac arrhythmias, sudden death, sleep disorders, hypertension and obesity. Objectives The present study aimed to investigate the impact of recreational football practice on the autonomic cardiac function of male children, as measured by heart rate variability. Patients and Methods Forty-seven male children aged 9 - 12 years were selected according to their engagement with football oriented practice outside school context. The children were divided into a football group (FG; n = 22 and a control group (CG; n = 25. The FG had regular football practices, with 2 weekly training sessions and occasional weekend matches. The CG was not engaged with any physical activity other than complementary school-based physical education classes. Data from physical activity, physical fitness, and heart rate variability measured in time and frequency domains were obtained. Results The anthropometric and body composition characteristics were similar in both groups (P > 0.05. The groups were also similar in time spent daily on moderate-to-vigorous physical activities (FG vs. CG: 114 ± 64 vs. 87 ± 55 minutes; P > 0.05. However, the FG performed better (P < 0.05 in Yo-Yo intermittent endurance test (1394 ± 558 vs. 778 ± 408 m and 15-m sprint test (3.06 ± 0.17 vs. 3.20 ± 0.23 s. Also, the FG presented enhanced autonomic function. Significant differences were detected (P < 0.05 between groups for low frequency normalized units (38.0 ± 15.2 vs. 47.3 ± 14.2 n.u (normalized units, high frequency normalized units (62.1 ± 15.2 vs. 52.8 ± 14.2 n.u., and LF:HF ratio (0.7 ± 0.4 vs. 1.1 ± 0.6 ms2. Conclusions Children engaged with regular football practice presented enhanced physical fitness and autonomic function, by increasing vagal tone at rest.

    Despite technological improvements in dialysis connectology and dialysis technique, peritonitis remains the most common and most significant complication of peritoneal dialysis (PD) in children. Most children undergoing chronic PD experience none or only one peritonitis episode, while others have multiple episodes or episodes secondary to unusual organisms. Knowledge of potential risk factors and likely patient outcome is imperative if treatment is to be optimized. In this review we will, in turn, describe episodes of peritonitis that are characterized as either relapsing, recurrent, repeat or zoonosis-related to highlight the clinical issues that are commonly encountered by clinicians treating these infections.

    AIM: Children who are uncooperative, due either to their age or medical condition, usually require sedation or a general anaesthetic (GA) to ensure immobility during magnetic resonance imaging (MRI) examination. These procedures have a risk of respiratory compromise and loss of vital reflexes. Melatonin induces a natural sleep with no known complication or risk of respiratory compromise. We aimed to evaluate the use of melatonin in these uncooperative children. MATERIAL AND METHODS: An unselected group of 40 children, who had been referred for an MRI examination of the brain under sedation or GA, were chosen to receive melatonin instead. They all received 10 mg of melatonin and 17 children additionally underwent some form of sleep deprivation. The number of children who went to sleep and had a successful MRI examination was recorded. RESULTS: Twenty-six children (65%) went to sleep and of these 22 (55%) had a successful MRI examination. In the 17 children who underwent sleep deprivation, 13 (76%) went to sleep and had a successful MRI examination. There was no complication. CONCLUSIONS: Melatonin may provide an alternative to conventional sedation regimes and GA for uncooperative children undergoing an MRI examination. The use of sleep deprivation improves the success rate and there is no risk of respiratory compromise. Johnson, K. et al. (2002)

    Coenzyme Q10 (CoQ10) is a lipid-soluble antioxidant that could have beneficial effects in patients undergoing cardiac surgery with cardiopulmonary bypass. There is no clear evidence about its clinical effects or a systematic review published yet. We aimed to conduct a systematic review and meta-analysis of the literature to elucidate the role of coenzyme Q10 in preventing complications in patients undergoing cardiac surgery with cardiopulmonary bypass. We searched the PubMed Database using the following keywords: Coenzyme Q10, ubiquinone, ubiquinol, CoQ10, Heart Surgery, Cardiac surgery. Articles were systematically retrieved, selected, assessed and summarized for this review. We performed separate meta-analyses for different outcomes (inotropic drug requirements after surgery, incidence of ventricular arrhythmias and atrial fibrillation, cardiac index 24 h after surgery and hospital stay), estimating pooled odds ratios (ORs) or mean differences of the association of CoQ10 administration with the risk of these outcomes. Eight clinical trials met our inclusion criteria. Patients with CoQ10 treatment were significantly less likely to require inotropic drugs after surgery {OR [95% confidence interval (CI) 0.47 (0.27-0.81)]}, and to develop ventricular arrhythmias after surgery [OR (95% CI) 0.05 (0.01-0.31)]. However, CoQ10 treatment was not associated with Cardiac index 24 h after surgery [mean difference (95% CI) 0.06 (-0.30 to 0.43)], hospital stay (days) [mean difference (95% CI) -0.61 (-4.61 to 3.39)] and incidence of atrial fibrillation [OR (95% CI) 1.06 (0.19-6.04)]. Since none of the clinical trials included in this review report any adverse effects associated to CoQ10 administration, and coenzyme Q10 has been demonstrated to be safe even at much higher doses in other studies, we conclude that CoQ10 should be considered as a prophylactic treatment for preventing complications in patients undergoing cardiac surgery with cardiopulmonary bypass. However, better

    Given the increasing numbers of cardiac device implantations worldwide, it is important to determine whether permanent endocardial leads across the tricuspid valve can promote tricuspid regurgitation (TR). Virtually all current data is retrospective, and indicates a signal of TR being increased after permanent lead implantation. However, the precise incidence of moderate or greater TR post-procedure, the exact mechanisms (mechanical, traumatic, functional), and the hemodynamic burden and clinical effects of this putative increase in TR, remain uncertain. We have therefore designed a multicenter, international, prospective study of 300 consecutive patients (recruitment completed, baseline data presented) who will undergo echocardiography and clinical assessment prior to, and at 1-year post device insertion. This prospective study will help determine whether cardiac device-associated TR is real, what are its potential mechanisms, and whether it has an important clinical impact on cardiac device patients.

    Full Text Available Background: Congestive Cardiac Failure (CCF is an important cause of morbidity and mortality among children. It results from various causes, but there are only very few reports from the African sub-region. Objectives: This study aimed to define the current trends in the prevalence and causes of CCF among children admitted to the Pediatrics Department of the Lagos State University Teaching Hospital (LASUTH. Patients and Methods;: This prospective study was conducted on all the consecutive patients admitted with diagnosis of CCF between January 2011 and December 2012. The data were analyzed using Microsoft Excel. Mean, median, and standard deviation were calculated as necessary. Continuous and discrete data were analyzed using student t-test and chi-square test, respectively. P < 0.05 was considered as statistically significant. Results: Out of the 5705 children admitted to the Department of Pediatrics of LASUTH, 156 ones (2.73% had CCF. The subjects’ age ranged from 48 hours to 144 months, with the mean age of 37.1 ± 31.94 months. The common causes of CCF were Acute Lower Respiratory Tract Infections (ALRTI (32.0%, Congenital Heart Diseases (CHD (31.4%, and severe anemia (28.8%. Other less common causes were septicaemia (3.84%, acquired heart diseases (3.2%, and renal disorders (0.6%. The rate of mortality was 17.3%, and more than 90% of the deaths occurred within 48 hours of admission. Conclusions: CCF remains a major cause of morbidity and mortality in Pediatric practice in Nigeria, with ALRTI, CHD, and severe anemia being the common causes.

    Full Text Available Needle fear is a common problem in children undergoing immunization. To ensure that the individual child’s needs are met during a painful procedure it would be beneficial to be able to predict whether there is a need for extra support. The self-reporting instrument facial affective scale (FAS could have potential for this purpose. The aim of this study was to evaluate whether the FAS can predict pain unpleasantness in girls undergoing immunization. Girls, aged 11-12 years, reported their expected pain unpleasantness on the FAS at least two weeks before and then experienced pain unpleasantness immediately before each vaccination. The experienced pain unpleasantness during the vaccination was also reported immediately after each immunization. The level of anxiety was similarly assessed during each vaccination and supplemented with stress measures in relation to the procedure in order to assess and evaluate concurrent validity. The results show that the FAS is valid to predict pain unpleasantness in 11-12-year-old girls who undergo immunizations and that it has the potential to be a feasible instrument to identify children who are in need of extra support to cope with immunization.

    Children with sickle cell disease (SCD) often undergo MRI studies to assess brain injury or to quantify hepatic iron. MRI requires the child to lie motionless for 30-60 min, thus sedation/anesthesia might be used to facilitate successful completion of exams, but this poses additional risks for SCD patients. To improve children's ability to cope with MRI examinations and avoid sedation, our institution established preparation and support procedures (PSP). To investigate the impact of PSP in reducing the need for sedation during MRI exams among children with SCD. Data on successful completion of MRI testing were compared among 5- to 12-year-olds who underwent brain MRI or liver R2*MRI with or without receiving PSP. Seventy-one children with SCD (median age 9.85 years, range 5.57-12.99 years) underwent a brain MRI (n = 60) or liver R2*MRI (n = 11). Children who received PSP were more likely to complete an interpretable MRI exam than those who did not 30 of 33; 91% vs. 27 of 38; 71%, unadjusted OR = 4.1 (P = 0.04) and OR = 8.5 (P < 0.01) when adjusting for age.

    Full Text Available Background. The aim of this study was to determine the incidence of pre- and postoperative vomiting in children undergoing a Video-Assisted Gastrostomy (VAG operation. Patients and Methods. 180 children underwent a VAG operation and were subdivided into groups based on their underlying diagnosis. An anamnesis with respect to vomiting was taken from each of the children’s parents before the operation. After the VAG operation, all patients were followed prospectively at one and six months after surgery. All complications including vomiting were documented according to a standardized protocol. Results. Vomiting occurred preoperatively in 51 children (28%. One month after surgery the incidence was 43 (24% in the same group of children and six months after it was found in 40 (22%. There was a difference in vomiting frequency both pre- and postoperatively between the children in the groups with different diagnoses included in the study. No difference was noted in pre- and postoperative vomiting frequency within each specific diagnosis group. Conclusion. The preoperative vomiting symptoms persisted after the VAG operation. Neurologically impaired children had a higher incidence of vomiting than patients with other diagnoses, a well-known fact, probably due to their underlying diagnosis and not the VAG operation. This information is useful in preoperative counselling.

    Full Text Available OBJECTIVE: An aging population and increasing use of percutaneous therapies have resulted in older patients with more co-morbidity being referred for cardiac surgery. Objective measurements of physiological reserve and severity of co-morbid disease are required to improve risk stratification. We hypothesised that FEV1 would predict mortality and length of stay following cardiac surgery. METHODS: We assessed clinical outcomes in 2,241 consecutive patients undergoing coronary artery bypass grafting and/or valve surgery from 2001 to 2007 in a regional cardiac centre. Generalized linear models of the association between FEV1 and length of hospital stay and mortality were adjusted for age, sex, height, body mass index, socioeconomic status, smoking, cardiovascular risk factors, long-term use of bronchodilators or steroids for lung disease, and type and urgency of surgery. FEV1 was compared to an established risk prediction model, the EuroSCORE. RESULTS: Spirometry was performed in 2,082 patients (93% whose mean (SD age was 67 (10 years. Median hospital stay was 3 days longer in patients in the lowest compared to the highest quintile for FEV1, 1.35-fold higher (95% CI 1.20-1.52; p<0.001. The adjusted odds ratio for mortality was increased 2.11-fold (95% CI 1.45-3.08; p<0.001 per standard deviation decrement in FEV1 (800 ml. FEV1 improved discrimination of the EuroSCORE for mortality. Similar associations were found after excluding people with known pulmonary disease and/or airflow limitation on spirometry. CONCLUSIONS: Reduced FEV1 strongly predicted increased length of stay and in-hospital mortality following cardiac surgery. FEV1 is a widely available measure of physiological health that may improve risk stratification of complex patients undergoing cardiac surgery and should be evaluated for inclusion in new prediction tools.

    Full Text Available To evaluate the effect of thoracic epidural anesthesia (TEA on tissue oxygen delivery and utilization in patients undergoing cardiac surgery. This prospective observational study was conducted in a tertiary referral heart hospital. A total of 25 patients undergoing elective off-pump coronary artery bypass surgery were enrolled in this study. All patients received thoracic epidural catheter in the most prominent inter-vertebral space between C7 and T3 on the day before operation. On the day of surgery, an arterial catheter and Swan Ganz catheter (capable of measuring cardiac index was inserted. After administering full dose of local anesthetic in the epidural space, serial hemodynamic and oxygen transport parameters were measured for 30 minute prior to administration of general anesthesia, with which the study was culminated. A significant decrease in oxygen delivery index with insignificant changes in oxygen extraction and consumption indices was observed. We conclude that TEA does not affect tissue oxygenation despite a decrease in arterial pressures and cardiac output.

    Purpose To evaluate if the preoperative administration of levosimendan in patients with right ventricular (RV) dysfunction, pulmonary hypertension, and high perioperative risk would improve cardiac function and would also have a protective effect on renal and neurological functions, assessed using two biomarkers neutrophil gelatinase-associated lipocalin (N-GAL) and neuronal enolase. Methods This is an observational study. Twenty-seven high-risk cardiac patients with RV dysfunction and pulmonary hypertension, scheduled for cardiac valve surgery, were prospectively followed after preoperative administration of levosimendan. Levosimendan was administered preoperatively on the day before surgery. All patients were considered high risk of cardiac and perioperative renal complications. Cardiac function was assessed by echocardiography, renal function by urinary N-GAL levels, and the acute kidney injury scale. Neuronal damage was assessed by neuron-specific enolase levels. Results After surgery, no significant variations were found in mean and SE levels of N-GAL (14.31 [28.34] ng/mL vs 13.41 [38.24] ng/mL), neuron-specific enolase (5.40 [0.41] ng/mL vs 4.32 [0.61] ng/mL), or mean ± SD creatinine (1.06±0.24 mg/dL vs 1.25±0.37 mg/dL at 48 hours). RV dilatation decreased from 4.23±0.7 mm to 3.45±0.6 mm and pulmonary artery pressure from 58±18 mmHg to 42±19 mmHg at 48 hours. Conclusion Preoperative administration of levosimendan has shown a protective role against cardiac, renal, and neurological damage in patients with a high risk of multiple organ dysfunctions undergoing cardiac surgery.

    International Nuclear Information System (INIS)

    Objective: To assess frequency of cardiac defects among children from birth to 12 years of age on each Methodology: A cross sectional study was conducted at echocardiography centre in coronary care unit at Bahawal Victoria Hby Paediatric Transthoracic echo probe; 2-D colour Doppler, Acuson CV-70 and Niemo-30 echocardiography machines. Mothers of children with cardiac defects were interviewed at the echocardiography centre. Variables included were A- Muscular plus Vascular defects; B- Valvular defects; C-Pericardial effusion; D- Dextrocardia and E- Congestive cardiac failure. History of children for sore throat followed by joint pains; history of mothers for drug intake (antihypertensive, antipyretic, anti-emetic, hypoglycaemic) as well as chronic diseases (diabetes mellitus, hypertension, anaemia) during pregnancy were surveyed. Parity of mothers, their cousin marriages, and family socio-economic status was also inquired. The results were tabulated, analyzed and finally subjected to suitable test of significant (SR of proportion) to find out statistical significant if any. Results: It was found that out of 150 patients, 76 (50.66%) were suffering from Cardiac muscular and Vascular defects, 61 (40.66%) Valvular defects, 7 (4.66%) Pericardial effusion, 2 (1.33%) Dextrocardia and 4 (2.66%) from Congestive Cardiac Failure. According to age, 54 (36%) were from birth to 3 years of age and 51 (34%) from 10 to 12 years. There was history of Rheumatic fever among 45 (30%) children. There were 106 (70.6%) children from lower socio-economic class and 79 (52.6%) parents had history of cousin marriages. Conclusion: Frequency of cardiac defects was more in children of male sex, lower socio-economic group, from birth to three years age and children from primipara mothers in our specified locality. Rheumatic fever, cousin's marriage, and prescribed drugs intake during pregnancy (for metabolic and hormonal disorders) were other contributors to cardiac defects. (author)

    Full Text Available Abstract Background Because previous studies have indicated that otitis media may be a polymicrobial disease, we prospectively analyzed middle ear effusions of children undergoing tympanostomy tube placement with multiplex polymerase chain reaction for four otopathogens. Methods Middle ear effusions from 207 children undergoing routine tympanostomy tube placement were collected and were classified by the surgeon as acute otitis media (AOM for purulent effusions and as otitis media with effusion (OME for non-purulent effusions. DNA was isolated from these samples and analyzed with multiplex polymerase chain reaction for Haemophilus influenzae, Streptococcus pneumoniae, Alloiococcus otitidis, and Moraxella catarrhalis. Results 119 (57% of 207 patients were PCR positive for at least one of these four organisms. 36 (30% of the positive samples indicated the presence of more than one bacterial species. Patient samples were further separated into 2 groups based on clinical presentation at the time of surgery. Samples were categorized as acute otitis media (AOM if pus was observed behind the tympanic membrane. If no pus was present, samples were categorized as otitis media with effusion (OME. Bacteria were identified in most of the children with AOM (87% and half the children with OME (51%, p Haemophilus influenzae was the predominant single organism and caused 58% of all AOM in this study. Alloiococcus otitidis and Moraxella catarrhalis were more frequently identified in middle ear effusions than Streptococcus pneumoniae. Conclusions Haemophilus influenzae, Streptococcus pneumoniae, Alloiococcus otitidis, and Moraxella catarrhalis were identified in the middle ear effusions of some patients with otitis media. Overall, we found AOM is predominantly a single organism infection and most commonly from Haemophilus influenzae. In contrast, OME infections had a more equal distribution of single organisms, polymicrobial entities, and non-bacterial agents.

Children are rarely anesthetized without IV access placement. We performed a retrospective study to determine our incidence of IV access placement during examinations under anesthesia (EUA and the incidence of adverse events that required intraoperative IV access placement.Methods: Data collected from our operating room (OR information system includes but is not limited to diagnosis, anesthesiologist, surgeon, and location of IV catheter (if applicable, patient’s date of birth, actual procedure, and anesthesia/procedure times. We reviewed the OR and anesthetic records of children (>1 month and <10 years who underwent EUAs between January 1, 2003 and May 31, 2009. We determined the percentage of children who were anesthetized without IV access placement, as well as the incidence of any adverse events that required IV access placement, intraoperatively.Results: We analyzed data from 3196 procedures performed during a 77-month period. Patients’ ages ranged from 1 month to 9 years. Overall, 92% of procedures were performed without IV access placement. Procedure duration ranged from 1–39 minutes. Reasons for IV access placement included parental preference for antinausea medication and/or attending preference for IV access placement. No child who underwent anesthesia without an IV line had an intraoperative adverse event requiring insertion of an IV line.Conclusion: Our data suggest that for

    Full Text Available AIM: Aim of our study to compare the spinal anaesthesia and general anaesthesia in children undergoing surgeries below umbilicus. OBJECTIVE: to assess the patient comfort in pt. with GA and pt. with spinal anaesthesia, the adequate surgical condition, assess the hemodynamic change, assess the post op analgesia and to assess the post op complication. MATERIAL AND METHOD: 60 ASA grade I & II children of either sex, aged 5-12 yrs undergoing elective surgeries for the lower abdominal, perineal and lower limb surgeries were taken. After taking a detailed history, thorough general physical examination, all pertinent investigation were carried out to exclude any systemic disease. Patients were classified randomly into 2 groups (30 patients in each group. Group A: General anesthesia was given. Group P: subarachnoid block was given. Intraoperative monitoring consisted of SPO2, PR, NIBP, RR and assessment of duration of post-operative analgesia. P-value <0.05 consider significant. RESULT: Analysis revealed that there were no significant differences between the patients with respect to age, sex, duration and type of surgery In SAB since less general anaesthetic drug including parental opioid are used the risk and postoperative respiratory depression is minimal. The stress response to surgery is also limited and recovery is fast. Postoperatively complications like sore throat, laryngeal irritation, cough etc. was also less associated with it. CONCLUSION pediatric spinal anesthesia is not only a safe alternative to general anesthesia but often the anesthesia technique of choice in many lower abdominal and lower limb surgeries in children. The misconception regarding its safety and flexibility is broken and is now found to be even more cost effective. It is much preferred technique special for common day case surgeries generally performed in the pediatric age group.

    Full Text Available The study was supported by the grant of the President of the Russian Federation MK-2076.2012.6. In the current study, the authors evaluated the role of relationship to disease in cardiac patients undergoing vital threat in the formation of the prediction of their mental adaptation in the distant post-hospital period. Longitudinal study (in-hospital and one year after discharge included two groups: patients with urgent cardiac status (N=47, 36 men, 11 women, age 34 to 66 years and patients with atrial arrhythmias, passing minimally invasive surgery (N=41, 22 men, 19 women, age 41 to 69 years. In-hospital stage used interviews and tests, questionnaires, and post-hospital stage was conducted using a telephone interview. We found that patients with a history of life-threatening cardiac condition, are less concerned about the disease than patients expecting to be relatively safe after minimally invasive surgery. In the forecast of the emotional status of patients, the severity of anxiety and disturbance of interpersonal relationships in the hospital period play an important role. Predictor of adherence to medical recommendations for men is a high disease concern, and in women – greater emotional stability.

    Full Text Available This study was carried to assess the efficacy of multimodal analgesia using ketorolac and fentanyl, for post-operative pain relief in children undergoing ambulatory eye surgery. Total of 161 children, aged 1 to 5 years, were randomly stratified to three different analgesic regimens: Group A Ketorolac 0.75 mg.kg -1 I.M. , Group B Fentanyl 0.75 µg.kg -1 I.V. and Group C Ketorolac 0.50mg.kg -1 I.M. and Fentanyl 0.50µg.kg -1 I.V. Ketorolac I.M. was given 45 minutes before extubation and fentanyl I.V. was given soon after extubation in the respective groups. Post-operative pain was assessed in a double blinded manner using Children′s Hospital of Eastern Onatario Pain Scale (CHEOPS scoring system and by recording the heart rate at 10, 30 and 60 minutes. If the score was above 8, the child was left with the parents. In case the score did not improve and persisted to be greater than 8, fentanyl 0.50µg.kg -1 I.V. was given as the rescue analgesia. The incidence of nausea, vomiting, sleep disturbances or any other complaints were recorded by a staff nurse 24 hours post operatively. Mean CHEOPS score at 10, 30 and 60 minutes and mean heart rate at 10 and 30 minutes were significantly higher for Group A compared with Group C. Mean pain score emerged significantly higher for Group B compared with Group C at 30 and 60 minutes, (P< 0.01. Rescue analgesia required was significantly higher in Group A compared to Groups B and C, (P< 0.0001. Post-operatively, significant incidence of drowsiness was reported in children in Group B compared to Groups A and C, (P< 0.01. A multimodal approach using both ketorolac and fentanyl at low doses produce effective and safe analgesia in children undergoing ambula-tory eye surgery.

  1. The relationship between cerebral oxygen saturation changes and post operative neurologic complications in patients undergoing cardiac surgery

    International Nuclear Information System (INIS)

    To study the relationship between cerebral oxygen saturation changes and postoperative neurologic complications. Seventy two adult patients with ASA class II, III who were scheduled for elective cardiac surgery, were randomized into three groups: Group I: with CPB (on -pump) Group II: without CPB (off- pump) Group III: valve surgery. Neuropsychological outcome was assessed by the Mini-Mental State Examination (MMSE). Cerebral oxygen saturation was also measured. There was no statistical difference in desaturation of more than 20% among three groups (P=0.113) but it was significant between group I and II (P=0.042). Changes of rSo/sub 2/ in different hours of surgery was significant in group I and group II (P=0.0001 in both) but it was not significant in group III ( P=0.075) . Although cerebral oximetry is a noninvasive and useful method of monitoring during cardiac surgery, it has low accuracy to determine postoperative neurologic complications. (author)

    Since the surgery for congenital heart disease (CHD) is considered highly risky, appropriate postoperative care is crucial. After the surgery, children are often discharged with unhealed wounds, incomplete recovery, and continuing pain. Health education programs based on empowerment education model can assist clients to develop skills in self-management. This study aimed to evaluate the effectiveness of an empowerment health education program for improving caregiving knowledge, caring behaviors, and self-efficacy of parents caring for children after corrective surgery for CHD. This prospective clinical trial enrolled pediatric patients undergoing surgical correction for CHD. Patients were divided into two groups: the control group (n = 42), which received the standard education program, and the intervention group (n = 44), which participated in the empowerment theory-based education program. We collected data on left ventricular ejection fraction (LVEF); peripheral oxygen saturation (SpO2); New York Heart Association classification of the patients; and the parents' caregiving knowledge, caring behaviors, and self-efficacy before surgery and one month and three months after surgery. At one month and three months after surgery, the intervention group scored higher than the control group in caregiving knowledge, caring behavior, and self-efficacy. By the third month after surgery, the intervention group had significantly higher values of LVEF and SpO2 than the control group. PMID:26105060

    Cardiac echinococcus is a rare affliction of the heart caused by the tapeworm Echinococcus granulosus. Primary echinococcosis of the heart represents 0.5-2% of all hydatid disease cases in endemic regions. It evolves slowly, explaining its rarity in children. We report the case of a 11-year-old child affected by a giant cardiac cyst of the left ventricle (LV). The patient underwent cardiac surgery and medical treatment. A retrospective review of the current literature was realized. We found 18 cases: the mean age was 11-years old. Nine cysts were localized in the LV, four in the interventricular septum, three in the right ventricle, and two in the right atrium. All underwent surgery except six patients. Routine echocardiographic screening may be useful in endemic regions where infestation is common. Cardiac echinococcus should be diagnosed in the early and uncomplicated stages and be removed surgically even in asymptomatic patients. PMID:25249763

    Full Text Available Abstract Objective: To evaluate the influence of pulmonary hypertension in the ultra-fast-track anesthesia technique in adult cardiac surgery. Methods: A retrospective study. They were included 40 patients divided into two groups: GI (without pulmonary hypertension and GII (with pulmonary hypertension. Based on data obtained by transthoracic echocardiography. We considered as the absence of pulmonary hypertension: a pulmonary artery systolic pressure (sPAP 40 mmHg associated with additional echocardiographic signs of PH. It was established as influence of pulmonary hypertension: the impossibility of extubation in the operating room, the increase in the time interval for extubation and reintubation the first 24 hours postoperatively. Univariate and multivariate analyzes were performed when necessary. Considered significant a P value <0.05. Results: The GI was composed of 21 patients and GII for 19. All patients (100% were extubated in the operating room in a medium time interval of 17.58±8.06 min with a median of 18 min in GII and 17 min in GI. PH did not increase the time interval for extubation (P=0.397. It required reintubation of 2 patients in GII (5% of the total, without statistically significant as compared to GI (P=0.488. Conclusion: In this study, pulmonary hypertension did not influence on ultra-fast-track anesthesia in adult cardiac surgery.

    Full Text Available PURPOSE: To ascertain perioperative morbimortality and identify prognostic factors for mortality among patients >55 years who undergo non-cardiac surgery. METHODS: A retrospective cohort of 403 patients relating to perioperative morbidity-mortality. Data were collected from a standardized protocol on gender, age, comorbidities, medications used, smoking, alcohol abuse, chronic use of benzodiazepine, nutritional status, presence of anemia, activities of daily living, American Society of Anesthesiology classification, Detsky's modified cardiac risk index - American College of Physicians, renal function evaluation, pulmonary risk according to the Torrington scale, risk of thromboembolic events, presence of malignant disease and complementary examinations. RESULTS: The mean age of the subjects was 70.8 ± 8.1 years. The "very old" (>80 years represented 14%. The mortality rate was 8.2%, and the complication rate was 15.8%. Multiple logistic regression showed that a history of coronary heart disease (OR: 3.75; p=0.02 and/or valvular heart disease (OR: 31.79; p=0.006 were predictors of mortality. The American Society of Anesthesiology classification was shown to be the best scale to mark risk (OR: 3.01; p=0.016. Nutritional status was a protective factor, in which serum albumin increases of 1 mg/dl decreased risk by 63%. DISCUSSION: The results indicate that serum albumin, coronary heart disease, valvular heart disease and the American Society of Anesthesiology classification could be prognostic predictors for aged patients in a perioperative setting. In this sample, provided that pulmonary, cardiac and thromboembolic risks were properly controlled, they did not constitute risk factors for mortality. Furthermore, continuous effort to learn more about the preoperative assessment of elderly patients could yield intervention possibilities and minimize morbimortality.

    Full Text Available BACKGROUND: Results from randomized controlled trials (RCT concerning cardiac and renal effect of remote ischemic preconditioning(RIPC in patients with stable coronary artery disease(CAD are inconsistent. The aim of this study was to explore whether RIPC reduce cardiac and renal events after elective percutaneous coronary intervention (PCI. METHODS AND RESULTS: RCTs with data on cardiac or renal effect of RIPC in PCI were searched from Pubmed, EMBase, and Cochrane library (up to July 2014. Meta-regression and subgroup analysis were performed to identify the potential sources of significant heterogeneity(I(2 ≥ 40%. Eleven RCTs enrolling a total of 1713 study subjects with stable CAD were selected. Compared with controls, RIPC significantly reduced perioperative incidence of myocardial infarction (MI [odds ratio(OR = 0.68; 95% CI, 0.51 to 0.91; P = 0.01; I(2 = 41.0%] and contrast-induced acute kidney injury(AKI (OR = 0.61; 95% CI, 0.38 to 0.98; P = 0.04; I(2 = 39.0%. Meta-regression and subgroup analyses confirmed that the major source of heterogeneity for the incidence of MI was male proportion (coefficient  = -0.049; P = 0.047; adjusted R(2 = 0.988; P = 0.02 for subgroup difference. CONCLUSIONS: The present meta-analysis of RCTs suggests that RIPC may offer cardiorenal protection by reducing the incidence of MI and AKI in patients undergoing elective PCI. Moreover, this effect on MI is more pronounced in male subjects. Future high-quality, large-scale clinical trials should focus on the long-term clinical effect of RIPC.

    Full Text Available Objective: The purpose of our study was to determine the effect of induced apnea on quality of cardiopulmonary structures during computerized tomographic (CT angiography images in children with congenital heart diseases. Methods: Pediatric patients with congenital heart defects undergoing cardiac CT angiography at our facility in the past 3 years participated in this study. The earlier patients underwent cardiac CT angiography without induced apnea and while, later, apnea was induced in patients, which was followed by electrocardiogram gated cardiac CT angiography. General anesthesia was induced using sleep dose of intravenous propofol. After the initial check CT, on request by the radiologist, apnea was induced by the anesthesiologist by administering 1 mg/kg of intravenous suxamethonium. Soon after apnea ensued, the contrast was injected, and CT angiogram carried out. CT images in the "apnea group" were compared with those in "nonapnea group." After the completion of the procedure, the patients were mask ventilated with 100% oxygen till the spontaneous ventilation was restored. Results: We studied 46 patients, of whom 36 with apnea and yet another 10 without. The quality of the image, visualization of structures such as cardiac wall, outflow tracts, lung field, aortopulmonary shunts, and coronary arteries were analyzed and subjected to statistical analysis (Mann-Whitney U, Fischer′s exact test and Pearson′s Chi-square test. In the induced apnea group, overall image quality was considered excellent in 89% (n = 33 of the studies, while in the "no apnea group," only 30% of studies were excellent. Absent or minimal motion artifacts were seen in a majority of the studies in apnea group (94%. In the nonapnea group, the respiratory and body motion artifacts were severe in 50%, moderate in 30%, and minimal in 20%, but they were significantly lesser in the apnea group. All the studied parameters were statistically significant in the apnea group in

  14. Cardiac diseases as a risk factor for stroke in Saudi children

    International Nuclear Information System (INIS)

    Objective was to ascertain the role of cardiac diseases as a risk factor for stroke in a cohort of Saudi children who were evaluated in a retrospective and prospective study. Children with cardiac diseases were identified from within a cohort of 104 Saudi children who presented with stroke. They were seen as inpatients in the Pediatric Wards or evaluated at the Outpatient Clinics of the Division of Pediatric Neurology (DPN), and the Division of Pediatric Cardiology at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia during the periods July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). A comprehensive form for clinical, neuroimaging, neurophysiological and laboratory data retrieval was designed and completed for each patient. Cardiac evaluation included 12-lead ECG and serial echocardiograms. Cardiac catheterization and 24-hour ambulatory ECG (Holter) were conducted on clinical discretion. Cardiac diseases were the underlying risk factor for stroke in 6 (5.8%) of the 104 children (aged one month to 12 years). The patients (4males and 2 females) were evaluated at the DPN at a mean age of 5.3 years (range=1-8 years; median 6.5 years). Onset of stroke was at a mean age of 34 months (range= 4 months - 8 years; median = 30 months). Five patients had stroke in association with congenital heart disease (CHD), whereas the sixth had restrictive cardiomyopathy. The identified CHD consisted of membranous ventricular septal defect in a 5-year-old boy who had moyamoya syndrome and sickle cell b-thalassemia, asymptomatic patent ductus arteriosus (PDA) in a 17-months-old girl, atrioventricular canal defect and PDA in an 8-year-old boy who also had Down syndrome, partial anomalous pulmonary venous drainage in a one-year-old boy. The latter patient developed hemiparesis secondary to a septic embolus, which evolved into brain abscess involving the right fronto-preital region. This was successfully managed surgically

    This study sought to evaluate the effectiveness of virtual reality (VR) enhanced interactive videogame distraction for children undergoing experimentally induced cold pressor pain and examined the role of avoidant and approach coping style as a moderator of VR distraction effectiveness. Sixty-two children (6-13 years old) underwent a baseline cold pressor trial followed by two cold pressor trials in which interactive videogame distraction was delivered both with and without a VR helmet in counterbalanced order. As predicted, children demonstrated significant improvement in pain tolerance during both interactive videogame distraction conditions. However, a differential response to videogame distraction with or without the enhancement of VR technology was not found. Children's coping style did not moderate their response to distraction. Rather, interactive videogame distraction with and without VR technology was equally effective for children who utilized avoidant or approach coping styles.

    Full Text Available OBJECTIVE: Noninvasive cardiac assessment of newborns and infants of women with systemic lupus erythematosus. The children had no congenital total atrioventricular block and were compared with the children of healthy women. METHODS: We prospectively assessed 13 newborns and infants aged 1 to 60 days, children of women with systemic lupus erythematosus and without congenital total atrioventricular block. These children were compared with 30 children of women who had no lupus or anti-Ro/SSA antibodies, and no risk factors for congenital heart disease either. Their age groups matched. The following examinations were performed: cardiological physical examination, electrocardiography, echocardiography, and signal-averaged electrocardiography. RESULTS: The statistical analysis showed no significant difference in ventricular function or in the cardiac conduction system between the groups. CONCLUSION: In regard to the conduction system and ventricular function in the absence of total atrioventricular block, no statistically significant difference was observed between the children of women with systemic lupus erythematosus and children of healthy women.

    The improvement in mortality rates for anesthetized children over the past 50 years reflects the many improvements that have been made in pediatric perioperative care. The modern pediatric anesthesiologist is better trained than the predecessors of half a century ago, and has a vastly improved arsenal of monitoring devices and anesthetic agents from which to choose. The modern pediatric perioperative environment is better equipped to meet the unique needs of children. Techniques practiced by surgeons, nurses, radiologists, and pharmacologists help create a far more sophisticated infrastructure than existed 50 years ago. Given these changes, it is not surprising that outcomes for patients have improved. PMID:11892500

  18. The deep inspiration breath hold technique using Abches reduces cardiac dose in patients undergoing left-sided breast irradiation

    International Nuclear Information System (INIS)

    We explored whether the deep inspiration breath hold (DIBH) technique using Abches during left-sided breast irradiation was effective for minimizing the amount of radiation to the heart and lung compared to free breathing (FB). Between February and July 2012, a total of 25 patients with left-sided breast cancer underwent two computed tomography scans each with the DIBH using Abches and using FB after breast-conserving surgery. The scans were retrospectively replanned using standardized criteria for the purpose of this study. The DIBH plans for each patient were compared with FB plans using dosimetric parameters. All patients were successfully treated with the DIBH technique using Abches. Significant differences were found between the DIBH and FB plans for mean heart dose (2.52 vs. 4.53 Gy), heart V30 (16.48 vs. 45.13 cm3), V20 (21.35 vs. 54.55 cm3), mean left anterior descending coronary artery (LAD) dose (16.01 vs. 26.26 Gy, all p 3 of the LAD (41.65 vs. 47.27 Gy, p = 0.017). The mean left lung dose (7.53 vs. 8.03 Gy, p = 0.073) and lung V20 (14.63% vs. 15.72%, p 0.060) of DIBH using Abches were not different significantly compared with FB. We report that the use of a DIBH technique using Abches in breathing adapted radiotherapy for left-sided breast cancer is easily feasible in daily practice and significantly reduces the radiation doses to the heart and LAD, therefore potentially reducing cardiac risk.

    Post-surgical chest tube removal (CTR) is associated with a significant pain and discomfort for patients. Current treatment strategies for reducing CTR-associated pain and anxiety are limited and partially efficacious. To determine the effects of cold application, inhalation of lavender essential oil, and their combination on pain and anxiety during CTR was investigated. This randomized controlled open-label trial was conducted with 80 patients in the cardiac surgery intensive care unit who had a chest tube for duration of at least 24 hours after coronary artery bypass grafting (CABG). Patients were randomized (n=20 in each group) to receive cold application, aromatherapy with lavender oil, cold application in combination with lavender oil inhalation, or none of the above interventions (control group). The intensity and quality of pain and anxiety were evaluated using the visual analogue scale, short form and modified-McGill pain questionnaire (SFM-MPQ) and the Spielberger situational anxiety level inventory (STAII) scale, respectively. Patients in all treatment groups had significantly lower pain intensity and anxiety compared with the control group immediately, 5, 10 and 15 min after CTR. There was no statistically significant difference in the SFM-MPQ total scores between the intervention groups. With respect to anxiety score, there was a significantly reduced anxiety level immediately after CTR in the aromatherapy and cold-aromatherapy combination groups versus the cold application group. The present results suggested the efficacy of cold application and aromatherapy with lavender oil in reducing pain and anxiety associated with post-CABG CTR. PMID:27047319

    ABSTRACT Objective: to verify the effectiveness of nursing orientation provided to families of patients in the immediate post-operative following cardiac surgery before the first visit to the post-anesthesia care unit, in decreasing anxiety levels, compared to the unit's routine orientation. Method: open randomized clinical trial addressing family members in the waiting room before the first visit in the immediate post-operative period. The family members assigned to the intervention group received audiovisual orientation concerning the patients' conditions at the time and the control group received the unit's routine orientation. Outcome anxiety was assessed using the STAI-State. Results: 210 individuals were included, 105 in each group, aged 46.4 years old on average (±14.5); 69% were female and 41% were the patients' children. The mean score obtained on the anxiety assessment in the intervention group was 41.3±8.6, while the control group scored 50.6±9.4 (p<0.001). Conclusion: a nursing intervention focused on providing guidance to families before their first visit to patients in the immediate post-operative period of cardiac surgery helps to decrease the levels of anxiety of companions, making them feel better prepared for the moment.

    Full Text Available A comparative assessment of cardiac performance by the data of clinical-instrumental examination of 50 patients aged 5-15 years with persisting form of partially-controlled atopic bronchial asthma in the period between the attacks of the disease was made. Children were divided into two groups depending on presence of concomitant chronic tonsillitis (18 patients or absence of the latter (32 patients. In all cases by the data of spirography in children against chronic tonsillitis in the period between the attacks of the disease there were revealed ventillation disorders in the lungs by obstruction type, this promoted elevation of pressure in the pulmonary artery. Only in this group of patients in 27,8% of cases pulmonary arterial hypertension of moderate severity was revealed. By echocardiography data in children with asthma against chronic tonsillitis reliably more often (р<0,01 there was revealed decrease of contractile function of myocardium of the left cardiac ventricle; this was caused by the presence of metabolic disturbances in the myocardium in the majority of cases (83,3%. These changes were registered on the electrocardiogram in the form of repolarisation changes of the ventricular complex. Presence of concomitant chronic tonsillitis in children with bronchial asthma favored formation of pulmonary hypertension on the one side and worsening of contractile ability of myocardium of the left cardiac ventricle on the other side; this required performing therapeutic-preventive measures for sanation of chronic infectious focus in the nasopharynx to prevent formation of chronic cardiac insufficiency during asthma course.

    Background Femoral artery thrombosis is one of the most common complications of catheterizations in infants and young children. This study was conducted to investigate the feasibility and effectiveness of thrombolytic therapy for femoral artery thrombosis after left cardiac catheterization in children.Methods Thrombolytic therapy with urokinase was carried out in children with femoral artery thrombosis after left cardiac catheterization. Each patient was given a bolus injection of heparin (100 U/kg). A bolus of urokinase (30 000-100 000 U) was injected intravenously, and then a continuous infusion of 10 000-50 000 U/h was administered. Transcatheter thrombolysis was performed once previous procedures failed.Results Eight patients (aged (3.1±2.3) years (8 months to 7 years), body weight (13.1±4.2) kg (7 to 20 kg)) presented lower limbs ischemia alter left cardiac catheterizations was performed. Seven patients accepted thrombolytic therapy with urokinase. In 5 patients, peripheral intravenous thrombolysis was successful with restoration of a normal pulse. In the other 3 cases, peripheral intravenous thrombolysis failed, followed by successful transcatheter thrombolysis. The average duration of therapy was (7.25±5.31) hours (1-17 hours). The average doses of heparin and urokinase were (1600±723) U (800-3000 U) and (268 571±177 240) U (50 000-500 000 U), respectively. There were no statistically significant differences in partial thromboplastin time before and during urokinase therapy ((40.6±22.3) to (49.9±39.2) seconds). However, the prothrombin time was significantly longer ((12.7±9.58) to (48.1±18.6) seconds, P<0.05). Patency of the target vessel was evaluated in all the patients for 2 weeks and no occlusion recurred.Conclusion Thrombolytic therapy with urokinase is a safe and useful modality in children with femoral artery thrombosis after left cardiac catheterization.

    Right ventricular (RV) performance is known to have prognostic value in patients with congestive heart failure (CHF). Cardiac resynchronisation therapy (CRT) has been found to enhance left ventricular (LV) energetics and metabolic reserve in patients with heart failure. The interplay between the LV and RV may play an important role in CRT response. The purpose of the study was to investigate RV oxidative metabolism, metabolic reserve and the effects of CRT in patients with CHF and left bundle brach block. In addition, the role of the RV in the response to CRT was evaluated. Ten patients with idiopathic dilated cardiomyopathy who had undergone implantation of a biventricular pacemaker 8{+-}5 months earlier were studied under two conditions: CRT ON and after CRT had been switched OFF for 24 h. Oxidative metabolism was measured using [{sup 11}C]acetate positron emission tomography (K{sub mono}). The measurements were performed at rest and during dobutamine-induced stress (5 {mu}g/kg per minute). LV performance and interventricular mechanical delay (interventricular asynchrony) were measured using echocardiography. CRT had no effect on RV K{sub mono} at rest (ON: 0.052{+-}0.014, OFF: 0.047{+-}0.018, NS). Dobutamine-induced stress increased RV K{sub mono} significantly under both conditions but oxidative metabolism was more enhanced when CRT was ON (0.076{+-}0.026 vs 0.065{+-}0.027, p=0.003). CRT shortened interventricular delay significantly (45{+-}33 vs 19{+-}35 ms, p=0.05). In five patients the response to CRT was striking (32% increase in mean LV stroke volume, range 18-36%), while in the other five patients no response was observed (mean change +2%, range -6% to +4%). RV K{sub mono} and LV stroke volume response to CRT correlated inversely (r=-0.66, p=0.034). None of the other measured parameters, including all LV parameters and electromechanical parameters, were associated with the response to CRT. In responders, RV K{sub mono} with CRT OFF was significantly lower

    Full Text Available Objective: this study aimed to determine the incidence of nosocomial infections, the risk factors and the impact of these infections on mortality among patients undergoing to cardiac surgery. Methods: Retrospective cohort study of 2060 consecutive patients from 2006 to 2012 at the Santa Casa de Misericórdia de Marília. Results: 351 nosocomial infections were diagnosed (17%, 227 non-surgical infections and 124 surgical wound infections. Major infections were mediastinitis (2.0%, urinary tract infection (2.8%, pneumonia (2.3%, and bloodstream infection (1.7%. The in-hospital mortality was 6.4%. Independent variables associated with non-surgical infections were age > 60 years (OR 1.59, 95% CI 1.09 to 2.31, ICU stay > 2 days (OR 5, 49, 95% CI 2.98 to 10, 09, mechanical ventilation > 2 days (OR11, 93, 95% CI 6.1 to 23.08, use of urinary catheter > 3 days (OR 4.85 95% CI 2.95 -7.99. Non-surgical nosocomial infections were more frequent in patients with surgical wound infection (32.3% versus 7.2%, OR 6.1, 95% CI 4.03 to 9.24. Independent variables associated with mortality were age greater than 60 years (OR 2.0; 95% CI 1.4 to3.0, use of vasoactive drugs (OR 3.4, 95% CI 1.9 to 6, 0, insulin use (OR 1.8; 95% CI 1.2 to 2.8, surgical reintervention (OR 4.4; 95% CI 2.1 to 9.0 pneumonia (OR 4.3; 95% CI 2.1 to 8.9 and bloodstream infection (OR = 4.7, 95% CI 2.0 to 11.2. Conclusion: Non-surgical hospital infections are common in patients undergoing cardiac surgery; they increase the chance of surgical wound infection and mortality.

    S100B protein has been recently proposed as a consolidated marker of brain damage and death in adult, children and newborn patients. The present study evaluates whether the longitudinal measurement of S100B at different perioperative time-points may be a useful tool to identify the occurrence of perioperative early death in congenital heart disease (CHD) newborns. We conducted a case-control study in 88 CHD infants, without pre-existing neurological disorders or other co-morbidities, of whom 22 were complicated by perioperative death in the first week from surgery. Control group was composed by 66 uncomplicated CHD infants matched for age at surgical procedure. Blood samples were drawn at five predetermined timepoints before during and after surgery. In all CHD children, S100B levels showed a pattern characterized by a significant increase in protein's concentration from hospital admission up to 24-h after procedure reaching their maximum peak (P<0.01) during cardiopulmonary by-pass and at the end of the surgical procedure. Moreover, S100B concentrations in CHD death group were significantly higher (P<0.01) than controls at all monitoring time-points. The ROC curve analysis showed that S100B measured before surgical procedure was the best predictor of perioperative death, among a series of clinical and laboratory parameters, reaching at a cut-off of 0.1 µg/L a sensitivity of 100% and a specificity of 63.7%. The present data suggest that in CHD infants biochemical monitoring in the perioperative period is becoming possible and S100B can be included among a series of parameters for adverse outcome prediction.

    Full Text Available By means of Doppler echocardiography there have been studied disturbances of intracardiac hemodynamics in 44 children aged 8-17 years with chronic rheumatic cardiac disease and developed mitral aortal and combined heart defects, as well as in chronic rheumatic cardiac disease without developed valvar defect. Differential approach has been defined to administration of inhibitors of angiotensin-converting factor in rheumatic heart defects: developed insufficiency of mitral and/or aortal valves II-III stage leads to remodeling of the left heart portions with developing chronic insufficiency of blood circulation, being an index for prolonged, not less than a year usage of the angiotensin-converting factor. In the presence of isolated mitral regurgitation, I stage in children with chronic rheumatic cardiac disease usage of the angiotensin-converting factor may be cancelled due to insignificant disturbances of valvar hemodynamics and a small risk of developing blood circulation insufficiency. Timely sanation of chronic infection foci in nasopharynx (conservative and surgical treatment of chronic tonsillitis, adenoid vegetations, therapy of hemolytic streptococcus presence decreases risk of developing rheumatic heart defect in children suffered acute rheumatic fever.

    We assessed the state of the autonomic nervous system in 90 children with diabetes mellitus type I. The autonomic dysfunction syndrome was found in 58,9% and diabetic cardiac autonomic neuropathy in 28,9% of patients. We revealed the high risk of the development of diabetic cardiac autonomic neuropathy in children with diabetes mellitus type I in the presence of the autonomic dysfunction syndrome. It has been shown that the early treatment of functional disturbances of the autonomic nervous system using transcranial magnetic stimulation is necessary to prevent the manifestation of diabetic cardiac autonomic neuropathy.

    Goal-directed therapy (GDT) encompasses guidance of intravenous (IV) fluid and vasopressor/inotropic therapy by cardiac output or similar parameters to help in early recognition and management of high-risk cardiac surgical patients. With the aim of establishing the utility of perioperative GDT using robust clinical and biochemical outcomes, we conducted the present study. This multicenter randomized controlled study included 130 patients of either sex, with European system for cardiac operative risk evaluation ≥3 undergoing coronary artery bypass grafting on cardiopulmonary bypass. The patients were randomly divided into the control and GDT group. All the participants received standardized care; arterial pressure monitored through radial artery, central venous pressure (CVP) through a triple lumen in the right internal jugular vein, electrocardiogram, oxygen saturation, temperature, urine output per hour, and frequent arterial blood gas (ABG) analysis. In addition, cardiac index (CI) monitoring using FloTrac™ and continuous central venous oxygen saturation (ScVO2) using PreSep™ were used in patients in the GDT group. Our aim was to maintain the CI at 2.5–4.2 L/min/m2, stroke volume index 30–65 ml/beat/m2, systemic vascular resistance index 1500–2500 dynes/s/cm5/m2, oxygen delivery index 450–600 ml/min/m2, continuous ScVO2 >70%, and stroke volume variation 30%, and urine output >1 ml/kg/h. The aims were achieved by altering the administration of IV fluids and doses of inotropes or vasodilators. The data of sixty patients in each group were analyzed in view of ten exclusions. The average duration of ventilation (19.89 ± 3.96 vs. 18.05 ± 4.53 h, P = 0.025), hospital stay (7.94 ± 1.64 vs. 7.17 ± 1.93 days, P = 0.025), and Intensive Care Unit (ICU) stay (3.74 ± 0.59 vs. 3.41 ± 0.75 days, P = 0.012) was significantly less in the GDT group, compared to the control group. The extra volume added and the number of inotropic dose adjustments were

    Full Text Available Introduction: Anaemia is associated with increased post-operative morbidity and mortality. We retrospectively assess the relationship between preoperative anaemia and in-hospital mortality in valvular cardiac surgical population. Materials and Methods: Data from consecutive adult patients who underwent valvular repair/ replacement at our institute from January 2010 to April 2014 were collected from hospital records. Anaemia was defined according to WHO criteria (hemoglobin <13g/dl for males and <12g/dl for females. 1:1 matching was done for anemic and non-anemic patients based on propensity for potentially confounding variables. Logistic regression was used to evaluate the relationship between anaemia and in-hospital mortality. MatchIt package for R software was used for propensity matching and SPSS 16.0.0 was used for statistical analysis. Results: 2449 patients undergoing valvular surgery with or without coronary artery grafting were included. Anaemia was present in 37.1% (33.91% among males & 40.88% among females. Unadjusted OR for mortality was 1.6 in anemic group (95% Confidence Interval [95% CI] - 1.041-2.570; p=0.033. 1:1 matching was done on the basis of propensity score for anaemia (866 pairs. Balancing was confirmed using standardized differences. Anaemia had an OR of 1.8 for mortality (95% CI- 1.042 to 3.094, P=0.035. Hematocrit of < 20 on bypass was associated with higher mortality. Conclusion: Preoperative anaemia is an independent risk factor associated with in-hospital mortality in patients undergoing valvular heart surgery.

    Full Text Available Objective: The aim of this study to evaluate the anxiety and expectancy among parents of children undergoing surgery in the multi-centric surgery units. Methods: Following approval from the ethics committee, a questionnaire was given to the parents of 123 children who were undergoing surgery in the multi-centric surgery units. The parents were informed that their answers would not affect the care given to their children. The questionnaire was evaluated using the State-Trait Anxiety Inventory (STAI-I and STAI-II. Results: The STAI results indicated that the parents’ anxiety level increased before their children underwent surgery. In addition, there was a negative correlation between STAI-II scores and high levels of wealth (p= 0.004. Also, those with steady employment and higher levels of education had lower anxiety levels and difference was significant (p=0.001. The state anxiety levels were unaffected by family income and education, but the trait anxiety levels decreased with increasing income and education. Mothers were less anxious if their child had undergone surgery in the past, while this result was not significant statistically (p>0.05. Parents were most commonly concerned with possible complications from the surgery and/or anesthesia. Conclusion: Results of our study indicate that parents of children undergoing surgery that have steady employment, to be informed, previously has been administered anesthesia or surgery, high level of wealth and education was observed less anxiety than others.

    Influenza is associated with significant morbidity and mortality in children receiving therapy for cancer, yet recommendation for, and uptake of the seasonal vaccine remains poor. One hundred children undergoing treatment for cancer were vaccinated with the trivalent inactivated influenza vaccine according to national guidelines in 2010 and 2011. Influenza-specific hemagglutinin inhibition antibody titers were performed on blood samples taken prior to each vaccination and 4 weeks following the final vaccination. A nasopharyngeal aspirate for influenza was performed on all children who developed an influenza-like illness. Following vaccination, seroprotection and seroconversion rates were 55 and 43% for H3N2, 61 and 43% for H1N1, and 41 and 33% for B strain, respectively. Overall, there was a significant geometric mean fold increase to H3N2 (GMFI 4.56, 95% CI 3.19-6.52, P children with solid compared with hematological malignancies and in children vaccinated study population, compared with 6.8% in unvaccinated controls, providing an adjusted estimated vaccine effectiveness of 72% (95% CI -26-94%). There were no serious adverse events and a low reactogenicity rate of 3%. The trivalent inactivated influenza vaccine is safe, immunogenic, provides clinical protection and should be administered annually to immunosuppressed children receiving treatment for cancer. All children <10 years of age should receive a two-dose schedule.

    Children undergoing magnetic resonance imaging examination frequently experience anxiety and fear before and during the scanning. The aim of the present study was to assess: i) whether and to what extent psychological interventions might reduce anxiety and fear levels; ii) whether the intervention is related to a decrease in the need for sedation. The interventions consisted of three activities: a clown show, dog interaction and live music. The emotional status (anxiety and fear) of the children was evaluated before and after the activities through a rating scale questionnaire. The results showed that the activities had high effectiveness in reducing the level of anxiety and fear and decreased the need for sedation in the experimental group compared to the control group. This approach proved to be a positive patient experience, helping to alleviate children's anxiety and fear, decreasing the need for sedation, and was cost-effective. PMID:25918624

    Full Text Available Background and Aims: Rapid recovery is desirable after neurosurgery as it enables early post-operative neurological evaluation and prompt management of complications. Studies have been rare comparing the recovery characteristics in paediatric neurosurgical patients. Hence, this study was carried out to compare the effect of sevoflurane and desflurane anaesthesia on emergence and extubation in children undergoing spinal surgery. Methods: Sixty children, aged 1-12 years, undergoing elective surgery for lumbo-sacral spinal dysraphism were enrolled. Anaesthesia was induced with sevoflurane using a face mask. The children were then randomised to receive either sevoflurane or desflurane with oxygen and nitrous oxide, fentanyl (1 μg/kg/h and rocuronium. The anaesthetic depth was guided by bispectral index (BIS ® monitoring with a target BIS ® between 45 and 55. Perioperative data with regard to demographic profile, haemodynamics, emergence and extubation times, modified Aldrete score (MAS, pain (objective pain score, agitation (Cole′s agitation score, time to first analgesic and complications, thereof, were recorded. Statistical analysis was done using STATA 11.2 (StataCorp., College Station, TX, USA and data are presented as median (range or mean ± standard deviation. Results: The demographic profile, haemodynamics, MAS, pain and agitation scores and time to first analgesic were comparable in between the two groups (P > 0.05. The emergence time was shorter in desflurane group (2.75 [0.85-12] min as compared to sevoflurane (8 [2.5-14] min (P < 0.0001. The extubation time was also shorter in desflurane group (3 [0.8-10] min as compared to the sevoflurane group (5.5 [1.2-14] min (P = 0.0003. Conclusion: Desflurane provided earlier tracheal extubation and emergence as compared to sevoflurane in children undergoing surgery for lumbo-sacral spinal dysraphism.

    Full Text Available Caudal epidural analgesia with bupivacaine is common in paediatric anaesthesia for providing intra and postoperative analgesia. But duration of analgesia even with bupivacaine; long acting anaesthetic is short only 4-6hrs. Hence, several adjuvants have been tried to prolong the duration of action of bupivacaine. We evaluated the efficacy of clonidine added to bupivacaine in prolonging the analgesic effect provided by caudal bupivacaine in children undergoing infra-umbilical surgery. Forty children, aged one to seven years, American Society of Anaesthesiologists (ASA Grade I/II, undergoing infra-umbilical surgery, were included in prospective randomized double blind study to one of two groups: caudal analgesia with 0.75 ml/kg of 0.25% bupivacaine in normal saline (Group A or caudal analgesia with 0.75ml/kg of 0.25% bupivacaine with 1 μg/kg of clonidine in normal saline (Group B. Post-operative pain was assessed for 24 hours using the Objective Pain Scale (OPS. The mean duration of analgesia was significantly longer in Group B (10.2 Hrs. than in Group A (4.2 1Hrs; P0.05. The requirement of rescue medicine was lesser in Group B. Clonidine as an adjunct to bupivacaine prolongs the post-operative pain relief in children and is safe compared to bupivacaine alone in paediatric infra umbilical surgeries.

Post-operative pain was assessed for 24 hours using the FLACC scale. The mean duration of analgesia was significantly longer in Group B (593.4 ± 423.3 min than in Group A (288.7 ± 259.1 min; P < 0.05. The pain score assessed using FLACC scale was compared between the two groups, and children in Group B had lower pain scores, which was statistically significant. The requirement of rescue medicine was lesser in Group B. Clonidine in a dose of 1 μg/kg added to 0.25% bupivacaine for caudal analgesia, during sub-umbilical surgeries, prolongs the duration of analgesia of bupivacaine, without any side effects.

  20. Follow-up of children exposed to ionising radiation from cardiac catheterisation: the Coccinelle study

    International Nuclear Information System (INIS)

    Cardiac catheterisation has become an essential tool in the diagnosis and treatment of children with a wide variety of congenital and acquired forms of cardiovascular disease. Despite the clear clinical benefit to the patient, radiation exposure from paediatric cardiac catheterisation procedures (CCPs) may be substantial. Given children's greater sensitivity to radiation and the longer life span during which radiation health effects can develop, an epidemiological cohort study, named Coccinelle or 'Ladybird' (French acronym for 'Cohorte sur le risque de cancer apres cardiologie interventionnelle pediatrique'), is carried out in France to evaluate the risks of leukaemia and solid cancers in this population. A total number of 8000 included children are expected. Individual CCP-related doses will be assessed for each child included in the cohort. For each CCP performed, dosimetric parameters (dose-area product, fluoroscopy time and total number of cine frames) are retrieved retrospectively. Organ doses, especially to the lung, the oesophagus and the thyroid, are calculated with PCXMC software. The cohort will be followed up through linkage with French paediatric cancer registries.

This study evaluated the impact of iohexol and iodixanol CA on fibrinolytic factors (tissue plasminogen activator [t-PA] and plasminogen activator inhibitor-1 [PAI-1], as well as platelet-monocyte conjugates in cardiac patients undergoing elective angiography in a double-blind, randomised parallel group study.Patients (men, 50-70 years old; n = 12 were randomised to receive either iohexol (Omnipaque; n = 6 or iodixanol (Visipaque; n = 6 during elective angiography at Raigmore Hospital, Inverness, UK. Arterial and venous blood samples were drawn prior to CA delivery and following angiography. Assessment of platelet-monocyte conjugation, t-PA and PAI-1 antigen and activity was conducted in samples pre- and post-angiography.Plasma t-PA antigen was depressed equally in the study groups after angiography, but there was a greater reduction in PAI-1 antigen in the group receiving iodixanol. These findings corresponded to a substantial reduction in t-PA activity in patients receiving iohexol, with no change in those receiving iodixanol (P = 0.023 between the CA groups. Both CAs caused a reduction in platelet-monocyte conjugation, with no difference between the groups. No adverse events were reported during the trial.Avoiding reduced plasma t-PA activity might be an important consideration in choosing iodixanol over iohexol in patients at risk of thrombosis following angiography.

    The relationship between eNO and events in the alveolar-capillary unit in acute lung injury remains to be established. Since endogenous eNO largely originates from the airway epithelium, but nitroglycerin (GTN)-induced eNO is due to microvascular/alveolar metabolism, we have proposed to use basal and GTN-induced eNO as metabolic markers of the airway--and microvascular/alveolar function, respectively. The current work investigates the relationship between basal and GTN-induced eNO and oxygenation parameters (PaO(2)/FiO(2) ratio) in patients undergoing cardiac surgery utilising cardiopulmonary bypass (CPB). Breath by breath eNO measurements were made in 10 patients before, and 1 and 3 h after CPB either under basal conditions or following intravenous administration of GTN (1, 2 and 3 microg/kg). Basal eNO remained unchanged, whereas GTN-induced eNO was reduced following CPB. Also, there was a transient reduction in PaO(2)/FiO(2) ratio 1 h after CPB (32+/-4 vs. 44+/-3 kPa). A negative correlation was found between oxygenation and basal eNO by Pearson's correlation test and linear regression analysis suggesting that decreased oxygenation was associated with increased basal eNO. In contrast, a decrease in GTN-induced eNO positively correlated with reduced oxygenation index (R=0.533, p=0.002). These data suggest that differential relationships exist between basal and nitrovasodilator-induced eNO and oxygenation indices during subclinical lung injury in patients following CPB and that GTN-induced eNO evolution may reflect better microvascular events and injury.

  4. Prevalence of long QT syndrome and other cardiac defects in deaf-mute children

    International Nuclear Information System (INIS)

    Background: Long QT syndrome is considered a fatal disease because of its association with ventricular arrhythmias and sudden cardiac death. Objectives of study were to determine the prevalence of long QT syndrome and other heart diseases, in deaf-mute children. Methods: A Cross-sectional descriptive study was conducted at Cholistan special education centre and Cardiology department, Sheikh Zayed hospital Rahim Yar Khan, Pakistan in September 2006. A total of 104 congenitally deaf-mute children were assessed. Height, weight and blood pressure measured, 12-lead electrocardiogram done and QTc calculated using Bazette's formula. Children with prolonged QTc underwent 24-hour ambulatory ECG recording. All were auscultated following complete protocol. A child with murmur was further evaluated with colour Doppler echocardiography. Audiometry was performed on all the children and the result interpreted according to WHO recommendations. Diagnosis of LQTS was based on Revised Schwartz criteria. Results: Out of 104 children, 62 were male with mean age 11.89 yrs. The average systolic and diastolic BP was 97/67 mmHg. Average height was 126 Cm. All children had moderate to severe bilateral sensorineural hearing loss (40-80 dB). One child had associated Patent Ductus Arteriosis. Fifteen had an innocent murmur. Prevalence of congenital heart disease was found to be 0.1/1000. Four children had QT interval more than 440 mSec, (range 0.46-0.47 mSec.). Both genders were equally affected. Three children had high probability of LQTS and one had intermediate probability. Screening of family of these 4 patients showed prolonged QT interval in the sibling of one patient. Conclusion: Our study highlights the significant prevalence of Jervell Lange-Nielsen Syndrome in Pakistani deaf-mute children, which may be associated to the high level of consanguinity in this region. Awareness of this syndrome among health care providers is needed as timely diagnosis and subsequent treatment may prevent

    Full Text Available Children undergoing magnetic resonance imaging examination frequently experience anxiety and fear before and during the scanning. The aim of the present study was to assess: i whether and to what extent psychological interventions might reduce anxiety and fear levels; ii whether the intervention is related to a decrease in the need for sedation. The interventions consisted of three activities: a clown show, dog interaction and live music. The emotional status (anxiety and fear of the children was evaluated before and after the activities through a rating scale questionnaire. The results showed that the activities had high effectiveness in reducing the level of anxiety and fear and decreased the need for sedation in the experimental group compared to the control group. This approach proved to be a positive patient experience, helping to alleviate children’s anxiety and fear, decreasing the need for sedation, and was cost-effective.

    Full Text Available End stage liver disease is often associated with growth retardation in children with congenital and hereditary diseases of hepatobiliary system. The aim was to investigate the serum growth hormone level before and after liver transplantation in 52 children with congenital and hereditary diseases of hepatobiliary system. Data of our research work revealed increased serum level of growth hormone in children with liver cirrhosis (3,32 ± 7,7 ng/ml vs. 1,16 ± 1,46 ng/ml in healthy children, p = 0,01, which correlates with PELD score (r = 0,62, p < 0,001. In a month after liver transplantation growth hormone concentration decreases (p < 0,001 and in a year after transplantation it doesn’t differ from healthy children. There wasn’t revealed any interaction between serum growth hormone level and anthropometric parameters before liver transplantation, but in a year after there was significant correlation between growth hormone concentration and height (r = 0,79, p = 0,01. Investigation of growth hormone level in children with liver cirrhosis and its evolution after liver transplantation is of interest as objective criterion of recovery of physical development regulation and as an additional parameter, which cor- relates with severity of end-stage liver disease.

    Purpose Fatigue is an important problem in children receiving intensive chemotherapy and hematopoietic stem cell transplantation (HSCT). Exercise may be an effective intervention for fatigue. Individualized yoga represents an ideal intervention because it can be tailored according to an individual child's needs. Little is known about how to structure a standardized yoga program for intensivelytreated children. Therefore, this study describes the development of a yoga program and an approach to monitoring sessions suitable for hospitalized children receiving intensive chemotherapy or HSCT. Methods The yoga program was designed to increase mobility in hospitalized children and to provide children with relaxation techniques that could be used independently in a variety of environments. The program was founded on 4 key tenets: safety, adaptability, environmental flexibility, and appeal to children. We also developed quality and consistency assurance procedures. Results A menu format with a fixed structure was selected for the yoga program. Each yoga session contained up to 6 sections: breathing exercises, warmup exercises, yoga poses, balancing poses, cool-down poses, and final relaxation. Yoga instructors selected specific yoga poses for each session from a predetermined list organized by intensity level (low, moderate, or high). Monitoring procedures were developed using videotaping and multirater adjudication. Conclusion We created a standardized yoga program and an approach to monitoring that are now ready for incorporation in clinical trials. Future work should include the adaptation of the program to different pediatric populations and clinical settings. PMID:27146130

    We retrospectively reviewed the imaging findings, indications, technique and clinical impact in children who had undergone chest CT while undergoing extra-corporeal membrane oxygenation (ECMO). Radiology and ECMO databases were searched to identify all 19 children who had undergone chest CT (20 scans in total) while on ECMO at our institution between May 2003 and May 2012. We reviewed all CT scans for imaging findings. Chest CT is performed in a minority of children on ECMO (4.5% in our series). Timing of chest CT following commencement of ECMO varied among patient groups but generally it was performed earlier in the neonatal group. Clinically significant imaging findings were found in the majority of chest CT scans. Many scans contained several findings, with most cases demonstrating parenchymal or pleural abnormalities. Case examples illustrate the spectrum of imaging findings, including underlying pathology such as necrotising pneumonia and severe barotrauma, and ECMO-related complications such as tension haemothoraces and cannula migration. The results of chest CT led to a change in patient management in 16 of 19 children (84%). There were no adverse events related to patient transfer. An understanding of scan technique and awareness of potential findings is important for the radiologist to provide prompt and optimal image acquisition and interpretation in appropriate patients.

    Full Text Available Background: Injured phrenic nerve secondary to cardiac surgeries is the most common cause of diaphragmatic paralysis (DP in infants. The aim of this study was to determine the risk factors for DP caused by congenital heart defect corrective surgeries in pediatrics.Methods: This cross-sectional study, conducted in a 2-year period (2006–2008, included 451 children with congenital heart diseases admitted to the Pediatric Cardiac Surgery Ward of Imam Khomeini Hospital. The diaphragmatic function was examined via fluoroscopy, and the frequency of DP and its relevant parameters were evaluated.Results: Of the 451 patients, comprising 268 males and 183 females at an age range of 3 days to 204 months (28.2 ± 33.4 months, 25 (5.5% infants (60% male and 40% female, age range = 15 days to 132 months, 41.2 ± 28.1 months had DP as follows: 48% unilateral right-sided and 36% unilateral left-sided. Additionally, 68% had cyanotic congenital heart disease and 84% had DP following total correction surgery.  The highest prevalence rates of DP resulting in phrenic hemiparesis were observed after arterial switch operation, Fontan procedure, and Blalock–Taussig shunt surgery, respectively. Thirteen (52% of the 25 DP patients underwent surgical diaphragmatic plication because of severe respiratory distress and dependency on mechanical ventilation, and most of the cases of plication underwent arterial switch operation. The rate of mortality was 24% (6 patients.Conclusion: DP with a prevalence of 5.5% was one of the most common complications secondary to cardiac surgeries in the infants included in the present study. Effective factors were age, weight, cyanotic congenital heart defects, and previous cardiac surgery. Diaphragmatic plication improved prognosis in severe cases.

    The recognition of the value of pain, especially in the pediatric population, has increased over the last decade. It is known that pain-related anxiety can increase perceived pain intensity. There are several different approaches to the treatment of pre-procedural anxiety and procedural pain in children. Melatonin, a neurohormone with the profile of a novel hypnotic-anaesthetic agent, plays an important role in anxiolysis and analgesia. This study investigated the effects of oral melatonin premedication to reduce anxiety and pain in children having blood samples taken. The investigations were carried out on 60 children, aged 1-14 years, divided into 2 equal groups. Using a computer-generated randomization schedule, patients were given either melatonin orally (0.5 mg/kg BW, max 5 mg) or placebo 30 min before blood draw. Pre-procedural anxiety was assessed using the scale from the Children’s Anxiety and Pain Scales, while procedural pain used the Face, Legs, Activity, Cry and Consolability assessment tool for children under the age of 3 years, Faces Pain Scale-Revised for children aged 3-8 years and Numeric Rating Scale for children over the age of 8 years. Oral administration of melatonin before the blood withdrawal procedure significantly reduced both anxiety (pchildren under 3 years and pchildren over 3 years). These data support the use of melatonin for taking blood samples due to its anxiolytic and analgesic properties. Further studies are needed to support the routine use of melatonin to alleviate anxiety and pain in pediatric patients having blood samples taken.

    Objectives: Triclofos may be a better sedative in view of better palatability and less gastric irritation as compared to chloral hydrate. This study aimed to assess the efficacy of triclofos (a commonly used sedative in India) as a sedative for sleep electroencephalogram (EEG) study in children. Methods: This prospective observational study was carried out in a tertiary care pediatric center. Consecutive children aged 6 months to 5 years referred for sleep EEG evaluation were recruited. Their clinical details were noted in a proforma after an informed consent. After a trial for natural sleep, oral triclofos was administered. Sleep parameters and adverse effects were noted. Results: One-hundred and sixty children were then enrolled. EEG was successfully recorded in 149 (93.1%) children. Median latency of sleep onset was 30 min and median duration of sleep was 90 min. The adverse effects in the following 24 h were mild and included dizziness, irritability, and vomiting. Conclusions: Oral triclofos was found to be an effective sedative for EEG in children with minimal adverse effects.

    Endoscopic procedures of the gastrointestinal tract were successfully introduced into paediatric practice in the 1970s. Recent expansive development has become useful for improvement of both diagnosis and treatment in many children with gastrointestinal diseases. Most of these procedures are performed under procedural sedation (PSA) knowing anatomical, physiological and psychological differences and requiring good experience from the paediatrician and anaesthesiologist. These principles help to provide the procedure safely and minimise adverse events, which are greater the smaller the child is. Procedural sedation and analgesia in healthy children can be performed by a paediatrician, but children with congenital defects and serious coexisting diseases (ASA ≥ III) and also during the usage of anaesthetics (e.g. propofol), should be managed by an anaesthesiologist.

    Individuals with sleep disordered breathing (SDB) can experience changes in automatic cardiac regulation as a result of frequent sleep fragmentation and disturbance in normal respiration and oxygenation that accompany most apnea/hypopnea events. In adults, these changes are reflected in enhanced sympathetic and reduced parasympathetic activity. In this study, we examined the autonomic cardiac regulation in children with and without SDB, through spectral and detrended fluctuation analysis (DFA) of pulse rate variability (PRV). PRV was measured from pulse-to-pulse intervals (PPIs) of the photoplethysmogram (PPG) recorded from 160 children using the Phone Oximeter(™) in the standard setting of overnight polysomnography. Spectral analysis of PRV showed the cardiac parasympathetic index (high frequency, HF) was lower (p < 0.01) and cardiac sympathetic indices (low frequency, LF and LF/HF ratio) were higher (p < 0.01) during apnea/hypopnea events for more than 95% of children with SDB. DFA showed the short- and long-range fluctuations of heart rate were more strongly correlated in children with SDB compared to children without SDB. These findings confirm that the analysis of the PPG recorded using the Phone Oximeter(™) could be the basis for a new screening tool for assessing PRV in non-clinical environment. PMID:26732019

    A nonpharmacological method can be an alternative or complement to analgesics.The aim of this study was to evaluate if music medicine influences pain and anxiety in children undergoing lumbar punctures. A randomized clinical trial was used in 40 children (aged 7-12 years) with leukemia, followed by interviews in 20 of these participants. The participants were randomly assigned to a music group (n = 20) or control group (n = 20). The primary outcome was pain scores and the secondary was heart rate, blood pressure, respiratory rate, and oxygen saturation measured before, during, and after the procedure. Anxiety scores were measured before and after the procedure. Interviews with open-ended questions were conducted in conjunction with the completed procedures. The results showed lower pain scores and heart and respiratory rates in the music group during and after the lumbar puncture. The anxiety scores were lower in the music group both before and after the procedure. The findings from the interviews confirmed the quantity results through descriptions of a positive experience by the children, including less pain and fear. PMID:20386063

    Background Preincisional local anesthetic infiltration at the surgical site is a therapeutic option for postoperative pain relief for pediatric inguinal hernia. Additionally, tramadol has been used as an analgesic for postoperative pain in children. Recently, the local anesthetic effects of tramadol have been reported. The aim of this study was to determine both the systemic analgesic and the local anesthetic effects of tramadol and to determine how it differs from bupivacaine when administered preincisionally. Methods Fifty-two healthy children, aged 2–7 years, who were scheduled for elective herniorrhaphy were randomly allocated to receive either preincisional infiltration at the surgical site with 2 mg/kg tramadol (Group T, n=26) or 0.25 mL/kg 0.5% bupivacaine (Group B, n=26). At the time of anesthetic administration, perioperative hemodynamic parameters were recorded. The pain assessments were performed 10 minutes after the end of anesthesia and during the first 6-hour period, using pain scores. The time of first dose of analgesia and need for additional analgesia were recorded. Results Between T and B groups, the anesthesia time, perioperative hemodynamic changes, and pain scores were not statistically different. However, in group B, the postoperative analgesic requirement was higher than in group T. Conclusion Tramadol shows equal analgesic effect to bupivacaine and decreases additional analgesic requirement, when used for preincisional infiltration anesthesia in children undergoing inguinal herniorrhaphy.

    Full Text Available By dopplerechocardiography method there was studied functional state of cardiac ventricles and character of hemodynamic disorders in 48 patients aged 5-17 years in attack period of moderately-severe and severe bronchial asthma. Group of comparison included 40 healthy peers. Disorders of central and peripheral hemodynamic in attack period of bronchial asthma in children were accompanied both by systolic and diastolic dysfunction of the left and right heart ventricles, herewith right ventricle was functioning in the mode of hyperdynamic, and left one – in the mode of hypodynamic. Combined systolic-diastolic variant of dysfunction both of right and left ventricles was developing in 58,3% of patients with moderately-severe and in 91,6% of patients with severe bronchial asthma. In the attack period of bronchial asthma in children equal directionality of systolic and diastolic dysfunction of heart ventricles was developing; this was characterized by synchronization of their function. Assessment of functional interaction of the ventricles under conditions of severe asthma attack showed direct and high (r=0,67 correlative interaction between finding of Tei index of the left and right ventricles, which characterize their systolic function; this, under conditions of increased hemodynamic pre-loading testified to compensatory increase of systolic interaction of ventricles. Direct and high (r=0,69 correlative interaction between time indices of isovolumic relaxation of the left and right ventricles, characterizing their diastolic function, testified to compensatory increase of diastolic interaction of ventricles under conditions of increase of hemodynamic post-loading. Imbalance of central and peripheral link of hemodynamic in attack period of bronchial asthma in children testified to development of cardiac insufficiency, which was compensated predominantly at the expense of increase of heart contractions rate.

    Full Text Available Major beta thalassemia (MBT is a hereditary disease which synthesies defects in beta chains of haemoglobin, it is causes red blood cell destruction and the symptoms of anemia. Red blood cell destruction, frequent blood transfusion and low adherence to routine use of iron chelator lead to iron accumulation in the heart, liver and endocrine organs. Accumulation of iron in the myocard can lead acute myocardial infarction. One of cardiac markers that had been used for the diagnosis of myocardial infarction was cardiac troponin I (cTnI. The aim of this research is find the correlation between serum ferritin levels and cTnI in MBT children. A descriptive analytic research was conducted using a cross sectional design. The subjects were divided into 2 groups, the MBT group and the control group. In both groups, the serum ferritin and cTnI levels ere evaluated. Data were analyzed using t-test and Pearson correlation test. Eleven children in the MBT group and 11 children in the control group were involved in this study. In the MBT group, the mean of serum ferritin and cTnI levels were 4292.5 µg/L and 0.20 ng/mL respectively. The mean of serum ferritin levels in the MBT group were higher than in the control and statistically significant (p= 0.0004. The mean of serum ferritin levels in the MBT group were higher than in the control and statistically significant (p= 0.0004. The mean of serum cTnI in the MBT group were higher than in the control, but statistically not significant (p= 0.82. In the MBT group, there was a weak corellation between serum ferritin and cTnI levels (r= 0.34.

    We conducted a retrospective study to determine the incidence of aspiration after supraglottoplasty at Riley Hospital for Children in Indianapolis. We reviewed the charts of 468 patients-281 males and 187 females, aged 2 days to 20 years-who had undergone supraglottoplasty for the treatment of laryngomalacia; most patients (69.9%) were aged 28 days to 2 years. A total of 47 patients (10.0%) experienced aspiration after supraglottoplasty; the overall association between supraglottoplasty and aspiration was not statistically significant (p = 0.25). Aspiration was positively correlated with age younger than 18 months, the performance of a revision procedure, the presence of an underlying neuromuscular disorder (n = 20), and the need for a postoperative gastrostomy tube (p < 0.001 for all). When the 20 patients with a neuromuscular disorder were excluded from our data analysis, the incidence of aspiration after supraglottoplasty fell to only 5.8% (27/468). We conclude that supraglottoplasty is a safe and effective procedure for the treatment of laryngomalacia. It does not significantly increase the overall incidence of aspiration in children, and thus the risk of aspiration should not be considered a deterrent to surgery, even in children with neuromuscular problems.

    Extracorporeal membrane oxygenation (ECMO) has traditionally been and, for the most part, still is being performed using roller pumps. Use of first-generation centrifugal pumps has yielded controversial outcomes, perhaps due to mechanical properties of the same and the ensuing risk of hemolysis and renal morbidity. Latest-generation centrifugal pumps, using magnetic levitation (ML), exhibit mechanical properties which may have overcome limitations of first-generation devices. This retrospective study aimed to assess the safety and efficacy of veno-arterial (V-A) ECMO for cardiac indications in neonates, infants, and children, using standard (SP) and latest-generation ML centrifugal pumps. Between 2002 and 2014, 33 consecutive neonates, infants, and young children were supported using V-A ECMO for cardiac indications. There were 21 males and 12 females, with median age of 29 days (4 days-5 years) and a median body weight of 3.2 kg (1.9-18 kg).

    Extracorporeal membrane oxygenation (ECMO) has traditionally been and, for the most part, still is being performed using roller pumps. Use of first-generation centrifugal pumps has yielded controversial outcomes, perhaps due to mechanical properties of the same and the ensuing risk of hemolysis and renal morbidity. Latest-generation centrifugal pumps, using magnetic levitation (ML), exhibit mechanical properties which may have overcome limitations of first-generation devices. This retrospective study aimed to assess the safety and efficacy of veno-arterial (V-A) ECMO for cardiac indications in neonates, infants, and children, using standard (SP) and latest-generation ML centrifugal pumps. Between 2002 and 2014, 33 consecutive neonates, infants, and young children were supported using V-A ECMO for cardiac indications. There were 21 males and 12 females, with median age of 29 days (4 days-5 years) and a median body weight of 3.2 kg (1.9-18 kg). Indication for V-A ECMO were acute circulatory collapse in ICU or ward after cardiac repair in 16 (49%) patients, failure to wean after repair of complex congenital heart disease in 9 (27%), fulminant myocarditis in 4 (12%), preoperative sepsis in 2 (6%), and refractory tachy-arrhythmias in 2 (6%).

    [Purpose] We investigated the effect exercise training has on cardiac autonomic nervous system (ANS) and cardiovascular risk profiles in children with type 1 diabetes mellitus (DM). [Subjects] Fifteen type 1 DM children (all boys; 13.0±1.0 years of age) were enrolled in the study. [Methods] The subjects received exercise training three times a week in a 12-week program. Each child was asked to walk on a treadmill to achieve an exercise intensity of VO2max 60%. ANS activity was measured by power spectral analysis of the electrocardiogram (ECG). Blood samples were obtained for serum lipid profiles. To evaluate Doppler-shifted Fourier pulsatility index (PI) analysis, a 5-MHz continuous wave Doppler (VASCULAB D10) set was used to measure forward blood flow velocity (FLOW) in the radial artery. [Results] Total and low-frequency (LF) power of heart rate variability increased significantly after exercise intervention. Total cholesterol (TC) levels were significant lower after exercise intervention. Total and high-frequency (HF) power were significantly correlated with higher TC levels, but diastolic blood pressure and HF was significantly correlated with lower TC levels. [Conclusion] Regular exercise intervention should be prescribed for children with type 1 DM.

    In patients with congenital heart disease, haemodynamic findings demonstrated on cardiac CT might provide useful hints for understanding the haemodynamics of cardiac defects. In contrast to morphological features depicted on cardiac CT, such haemodynamic findings on cardiac CT have not been comprehensively reviewed in patients with congenital heart disease. This article describes normal haemodynamic phenomena of cardiovascular structures and various abnormal haemodynamic findings with their mechanisms and clinical significance on cardiac CT in patients with congenital heart disease.

    Rapid maxillary expansion (RME) is a widely used practice in orthodontics. Scientific evidence shows that RME can be helpful in modifying the breathing pattern in mouth-breathing patients. In order to promote the restoration of physiological breathing we have developed a rehabilitation program associated with RME in children. The aim of the study was a literature review and a model of orofacial rehabilitation in children with obstructive sleep apnea undergoing treatment with rapid maxillary expansion. Muscular training (local exercises and general ones) is the key factor of the program. It also includes hygienic and behavior instructions as well as other therapeutic procedures such as rhinosinusal washes, a postural re-education (Alexander technique) and, if necessary, a pharmacological treatment aimed to improve nasal obstruction. The program should be customized for each patient. If RME is supported by an adequate functional rehabilitation, the possibility to change the breathing pattern is considerably amplified. Awareness, motivation and collaboration of the child and their parents, as well as the cooperation among specialists, such as orthodontist, speech therapist, pediatrician and otolaryngologist, are necessary conditions to achieve the goal.

    Six uremic dhildren in periodic hemodialysis with protein-calorie malnutrition were studied. Three of them were given diet supplementation with a compound constituted by carbohydrates and essential amino acids. Evaluation at ,3 and 6 months with somatometry, rutine laboratory analysis, intravenous glucose tolerance test and plasma amino acid determinations, showed that patients with diet supplementation had a slight increase in height and body weight, improved glucose in tolerance, that was initialy detected, and an abnormal pattern of plasma amino acids not modified during the study. Patients without diet supplementation showed no changes in height, body weight, glucose tolerance and plasma amino acids. These results suggest that diet supplementation with carbohydrates and amino acids is useful to improve nutrition in uremic children on hemodialysis, but it is neccesary to study more patients.

    The appropriate pain management in neonates and children is lacking. Factors that prevent the execution of proper pain relief vary from center to center. We studied the factors responsible for it in a surgical unit. We conducted a survey at a tertiary-level institute among the resident doctors and nursing staff by means of an informal questionnaire analyzing their basic knowledge. The questions pertained mainly to pain assessment, analgesic usage, role of opioids, and formal training, and the responses so obtained were analyzed under these four headings. Seventy-three percent (22/30) of the residents and 74% (26/35) of the nursing staff knew about pain assessment scoring system in pediatric patients. However, assessment of pain in emergency cases was always done by only 6.6% of the residents. Effect of analgesia on severity of pain was never recorded by 33% (10/30) of the residents. Eighty-six percent (26/30) of the residents and 91% (32/35) of the nursing staff had adequate knowledge about analgesic dosage and interval for routine use. Ten of the 30 (33%) residents believed that analgesic administration in an acute abdomen, before definitive diagnosis, will always mask the symptoms. During a minor procedure, 56% (17/30) of the residents always used analgesia. Only 3.3% (1/30) of residents and 2.8% (1/35) of the nursing staff had received a structured training for pain management. Although, 93% (28/30) of the residents claimed to know about the safety of use of opioids, only 46% (14/30) used them routinely as analgesics. Pain management in surgical neonates and children is often ignored. Lack of formal training, inadequate knowledge, and standard protocols are the barriers in our setup, which may in turn be due to overwhelming attention given to the surgical condition. PMID:26654407

    Full Text Available Objective: To compare the glycemic control and lipid profile of children and adolescents undergoing two different dietetic treatments for type 1 Diabetes Mellitus assisted at the Children and Adolescent´s Diabetes Mellitus Health Center-UFRJ. Methods: A retrospective longitudinal study conducted between 2002 and 2006. We evaluated the same subjects in two different periods: after 1 year in TD and subsequently after 1 year in CCHO. The evolution of the nutritional status during the dietary treatments was evaluated using Body Mass Index (BMI for age. The lipid panel was evaluated according to the 1st Guideline for Prevention of Atherosclerosis in Childhood and Adolescence, used in Brazil, and the glycemic control was evaluated by measuring glycated hemoglobin (HbA1c. Results: We evaluated 93 individuals, 38.7% children and 61.3% adolescents. The mean age at study entry was 11.1 (± 2.66 years and the mean disease duration was 6.1 (± 3.2 years. A significant difference in the percentage of adequacy of HbA1c (p = 0.000 and in the values of total plasma cholesterol (p = 0.043 was found after 1 year of CCHO diet, which did not happen during the observation time of TD. The evolution of anthropometric nutritional status showed no significant difference between the beginning and the end of both dietary treatments. Conclusion: The results of this study suggest that a more flexible food orientation program can contribute to the improvement of blood glucose levels without causing deterioration of the lipid profile when compared to TD.

    Recent improvements in toxicity profiles of pediatric oncology patients are attributable, in part, to advances in the field of radiation oncology such as intensity modulated radiation (IMRT) and proton therapy (IMPT). While IMRT and IMPT deliver highly conformal dose to targeted volumes, they commonly demand the addition of 2- or 3-dimensional imaging for precise positioning--a technique known as image guided radiation therapy (IGRT). In this manuscript we address strategies to further minimize exposure risk in children by reducing effective IGRT dose. Portal X rays and cone beam computed tomography (CBCT) are commonly used to verify patient position during IGRT and, because their relative radiation exposure is far less than the radiation absorbed from therapeutic treatment beams, their sometimes significant contribution to cumulative risk can be easily overlooked. Optimizing the conformality of IMRT/IMPT while simultaneously ignoring IGRT dose may result in organs at risk being exposed to a greater proportion of radiation from IGRT than from therapeutic beams. Over a treatment course, cumulative central-axis CBCT effective dose can approach or supersede the amount of radiation absorbed from a single treatment fraction, a theoretical increase of 3% to 5% in mutagenic risk. In select scenarios, this may result in the underprediction of acute and late toxicity risk (such as azoospermia, ovarian dysfunction, or increased lifetime mutagenic risk) in radiation-sensitive organs and patients. Although dependent on variables such as patient age, gender, weight, body habitus, anatomic location, and dose-toxicity thresholds, modifying IGRT use and acquisition parameters such as frequency, imaging modality, beam energy, current, voltage, rotational degree, collimation, field size, reconstruction algorithm, and documentation can reduce exposure, avoid unnecessary toxicity, and achieve doses as low as reasonably achievable, promoting a culture and practice of "gentle IGRT

    To minimize perloperative cardiac events, we utilize a screening protocol consisting of intravenous dipyridamole thallium-201 myocardial imaging (DPT), with the selective use of coronary angiography based on the presence of reversible defect(s) on DPT test. A retrospective study was performed to determine the prognostic value of this protocol and to identify any clinical parameters predictive of an abnormal DPT test. To accomplish this, a detailed chart analysis of 176 consecutive kidney (n = 89) and kidney-pancreas (n = 87) transplant recipients who had undergone pre-transplant DPT testing was performed. The results of the DPT test were interpreted as normal in 111, fixed defect in 15, and reversible defect(s) in 50 patients. Forty-two of the 50 patients with reversible defect(s) underwent coronary angiography. Twelve of the 27 patients with significant coronary artery disease (CAD, > 50% stenosis in one or more coronary arteries) underwent pre-transplant revascularization and the remaining 15 were treated medically. Cardiac events (documented acute myocardial infarction or sudden cardiac death) within 6 wk of transplant were stratified by the results of this protocol. Also, various clinical parameters were compared between patients with normal and abnormal (fixed and reversible defect) DPT tests. Only one of the 111 (0.9%) transplant recipients with a normal DPT test had a perioperative cardiac event. None of the 15 (0%) patients with a fixed defect and none of the 15 (0%) patients with reversible defect(s), but a nonsignificant (<50% narrowing) coronary angiogram, had a perioperative cardiac event. Three of the 27 (11.1%) patients with reversible defect(s) and significant disease on coronary angiography, who had undergone pre-transplant revascularization of were managed medically, had a perioperative coronary event. Of 14 recipients parameters analyzed, age > 50 yr was the only variable predictive of an abnormal DPT test. (au) 33 refs.

    Full Text Available High cumulative doses of anthracyclines (300–500 mg/m2 used in the treatment of children with cancer may result in cardiotoxicity, a major long-term adverse effect that limits clinical usefulness of this class of chemotherapeutic agents. We assessed anthracycline-induced cardiotoxicity by measuring Pro-BNP levels and echocardiographic (ECHO findings and investigated potential protective effect of selenium (Se supplementation in a group of pediatric cancer patients. Plasma level of Pro-BNP was measured, and ECHO was performed in 67 patients (45 boys, 22 girls; ages 2–18 years; median age 12 years after they completed anthracycline-containing chemotherapy. Serum Se level was measured in 37 patients. Eleven patients had high Pro-BNP levels and/or cardiac failure with Pro-BNP levels of 10–8,022 pg/mL (median 226.3 pg/mL; laboratory normal level is less than 120 pg/mL. Serum Se levels were low (20–129 mcg/L, median 62 mcg/L in ten of these eleven patients. Eight of 10 patients with low Se and high Pro-BNP levels were supplemented with Se 100 mcg/day for a period of 4–33 months (median 6 months which resulted in improvement in Pro-BNP and/or ECHO findings. These results suggest that Se supplementation may have a role in protection against anthracycline-induced cardiac toxicity.

    The use of physical punishment for children is associated with poor psychological and behavioral outcomes, but the causal pathway is controversial, and the effects on later physical health unknown. We conducted a cross-sectional survey of asthma, cancer, and cardiac patients (150 in each category, 75 male) recruited from outpatient clinics and 250 healthy controls (125 male). All participants were 40-60 years old and citizens of Saudi Arabia, where the use of beating and insults is an acceptable parenting style. Demographic data and recalled frequency of beatings and insults as a child were assessed on an 8-point scale. Beating and insults were highly correlated (ρ = 0.846). Propensity score matching was used to control for demographic differences between the disease and healthy groups. After controlling for differences, more frequent beating (once or more per month) and insults were associated with a significantly increased risk for cancer (RR = 1.7), cardiac disease (RR = 1.3) and asthma (RR = 1.6), with evidence of increased risk for cancer and asthma with beating frequency of once every 6 months or more. Our results show that a threatening parenting style of beating and insults is associated with increased risk for somatic disease, possibly because this form of parenting induces stress. Our findings are consistent with previous research showing that child abuse and other early life stressors adversely affect adult somatic health, but provide evidence that the pathogenic effects occur also with chronic minor stress. A stress-inducing parenting style, even when normative, has long term adverse health consequences. PMID:23054177

  11. Prophylaxis of mucosal toxicity by oral propantheline and cryotherapy in children with malignancies undergoing myeloablative chemo-radiotherapy

    International Nuclear Information System (INIS)

    Mucosal toxicity is an incapacitating complication of intensive chemo-radiotherapy for children with malignant disorders, and is physically and psychologically distressful. It is therefore important to minimize mucosal toxicity in those patients. In this report, the effects of the combined prophylaxis of oral cooling (cryotherapy) and administration of propantheline, an anticholinergic drug, were studied in patients (aged 2-16 year) with acute leukemias or solid tumors, who underwent myeloablative chemo-radiotherapy and autologous peripheral blood stem cell rescue from 1993 to 1997. Patients were pretreated with the combined prophylaxis (n=12) or single prophylaxis (n=5), or left untreated (n=7). The combined prophylaxis significantly reduced the severe mucositis (combined, 8.3%; single, 20.0%; and untreated, 42.9%) and severe diarrhea (combined, 16.7%; single, 60.0%; and untreated, 57.1%). Moreover, the combined prophylaxis tended to shorten the periods of febrile episodes defined as temperature >38 deg C (combined, 3.8 days; single, 4.6 days; and untreated, 5.6 days). Therefore, the combination of propantheline and oral cryotherapy may be feasible and effective for reduction of mucosal toxicity in patients with malignancy who undergo high-dose chemotherapy.

    Full Text Available Abstract Objective: To investigate the efficiency of short-term inspiratory muscle training program associated with combined aerobic and resistance exercise on respiratory muscle strength, functional capacity and quality of life in patients who underwent coronary artery bypass and are in the phase II cardiac rehabilitation program. Methods: A prospective, quasi-experimental study with 24 patients who underwent coronary artery bypass and were randomly assigned to two groups in the Phase II cardiac rehabilitation program: inspiratory muscle training program associated with combined training (aerobic and resistance group (GCR + IMT, n=12 and combined training with respiratory exercises group (GCR, n=12, over a period of 12 weeks, with two sessions per week. Before and after intervention, the following measurements were obtained: maximal inspiratory and expiratory pressures (PImax and PEmax, peak oxygen consumption (peak VO2 and quality of life scores. Data were compared between pre- and post-intervention at baseline and the variation between the pre- and post-phase II cardiac rehabilitation program using the Student's t-test, except the categorical variables, which were compared using the Chi-square test. Values of P<0.05 were considered statistically significant. Results: Compared to GCR, the GCR + IMT group showed larger increments in PImax (P<0.001, PEmax (P<0.001, peak VO2 (P<0.001 and quality of life scores (P<0.001. Conclusion: The present study demonstrated that the addition of inspiratory muscle training, even when applied for a short period, may potentiate the effects of combined aerobic and resistance training, becoming a simple and inexpensive strategy for patients who underwent coronary artery bypass and are in phase II cardiac rehabilitation.

    Remote ischemic preconditioning (RIPC) may attenuate acute kidney injury (AKI). However, results of studies evaluating the effect of RIPC on AKI after cardiac surgery have been controversial and contradictory.The aim of this meta-analysis is to examine the association between RIPC and AKI after on-pump cardiac surgery.The authors searched relevant studies in PubMed, EMBASE, and the Cochrane Library through December 2015.We considered for inclusion all randomized controlled trials that the role of RIPC in reducing AKI and renal replacement therapy (RRT) among patients underwent on-pump cardiac surgical procedures.We collected the data on AKI, initiation of RRT, serum creatinine (sCr) levels, and in-hospital mortality. Random- and fixed-effect models were used for pooling data.Nineteen trials including 5100 patients were included. The results of this meta-analysis showed a significant benefit of RIPC for reducing the incidence of AKI after cardiac interventions (odds ratio [OR] = 0.84; 95% confidence interval [CI], 0.73-0.98; P = 0.02). No significant difference was found in the incidence of RRT between RIPC and control (OR, 0.76, 95% CI, 0.46-1.24; P = 0.36). In addition, compared with standard medical care, RIPC showed no significant difference in postoperative sCr (IV 0.07; 95% CI, -0.03 to 0.16; P = 0.20; postoperative day 1; IV 0.00; 95% CI, -0.08 to 0.09; P = 0.92; postoperative day 2; IV 0.04; 95% CI, -0.05 to 0.12; P = 0.39; postoperative day 3), and in-hospital mortality (OR, 1.21, 95% CI, 0.64-2.30; P = 0.56).According to the results from present meta-analysis, RIPC was associated with a significant reduction AKI after on-pump cardiac surgery but incidence of RRT, postoperative sCr, and in-hospital mortality. Further high-quality randomized controlled trials and experimental researches comparing RIPC are desirable. PMID:27631199

    The end-of-life (EOL) experience of children who undergo stem cell transplantation (SCT) may differ from that of other children with cancer. To evaluate perspectives and patterns of EOL care after SCT, we surveyed 141 parents of children who died of cancer (response rate, 64%) and their physicians. Chart review provided additional information. Children for whom SCT was the last cancer therapy (n = 31) were compared with those for whom it was not (n = 110). SCT parents and physicians recognized no realistic chance for cure later than non-SCT peers (both P < .001) and were more likely to have a primary goal of cure at death (parents, P < .001; physicians, P = .02). SCT children were more likely to suffer highly from their last cancer therapy and die in the intensive care unit (both P < .001), with less opportunity for EOL preparation. SCT parents who recognized no realistic chance for cure more than 7 days before death along with the physician were more likely to prepare for EOL, and if their primary goal was to reduce suffering, to achieve this (P < .001). SCT is associated with significant suffering and less opportunity to prepare for EOL. Children and families undergoing SCT may benefit from ongoing discussions regarding prognosis, goals, and opportunities to maximize quality of life. PMID:20228275

    Full Text Available Introduction. Search for harmless and simultaneously effective probiotics, which could be successfully used for treatment and prevention of infectious deseases, is currently important. A. viridans is of particular interest, as it is representative of the normal microflora of human with broad spectrum of antibacterial action. The use of this microorganism has a number of advantages: the absence of side effects on the body; high adhesive abilities; resistance to lysozyme in saliva; the ability of use in patients, sensitized to antibiotics and chemotherapeutic drugs; stimulation effects on the human immune system. Material and methods. The purpose of the study was to investigate the antagonism of A. viridans № 167 and autostrains of aerococcuses, isolated at patients, to conditionally - pathogenic microflora of the nose and oropharynx of children with cardiac patology. At the first stage of the study the microflora of the of the nose and oropharynx of 2 investigated categories was examined – 40 children 4-14 years with cardiac patology and 40 healthy children 4-5 years old. The second stage of work was to study the effect of A. viridans on the explored strains. Results and discussion. A. viridans manifests the antagonism to all studied strains of gram-positive and gram-negative microorganisms, except C. albisans. A. viridans antagonistic activity to staphylococci (10 + 3 mm and streptococci (10 + 2mm is at the approximately same level. It is interesting to compare the antagonism of aerococcuses to clinical isolates of S. pyogenes and similar strains from carriers (healthy children category. Impact of aerococcuses on P. mirabilis strain appeared at the highest level. Autosimbionts of A. viridans, isolated from healthy children, are more antagonistic to CPM strains, isolated from these children, than autostrains of A. viridans, isolated from children with with cardiac patology, and higher than the museum strain of A. viridans № 167 antagonism

    Full Text Available Background: Anxiety is an emotional state characterized by apprehension and fear resulting from anticipation of a threatening event. Objectives: The present study aimed to analyze the incidence and level of preoperative anxiety in the patients scheduled for cardiac surgery by using a Visual Analogue Scale for Anxiety (VAS-A and Amsterdam Preoperative Anxiety and Information Scale (APAIS and to identify the influencing clinical factors. Patients and Methods: This prospective, longitudinal study was performed on 300 cardiac surgery patients in a single university hospital. The patients were assessed regarding their preoperative anxiety level using VAS-A, APAIS, and a set of specific anxiety-related questions. Their demographic features as well as their anesthetic and surgical characteristics (ASA physical status, EuroSCORE, preoperative Length of Stay (LoS, and surgical history were recorded, as well. Then, one-way ANOVA and t-test were applied along with odds ratio for risk assessment. Results: According to the results, 94% of the patients presented preoperative anxiety, with 37% developing high anxiety (VAS-A ≥ 7. Preoperative LoS > 2 days was the only significant risk factor for preoperative anxiety (odds ratio = 2.5, CI 95%, 1.3 - 5.1, P = 0.009. Besides, a positive correlation was found between anxiety level (APAISa and requirement of knowledge (APAISk. APAISa and APAISk scores were greater for surgery than for anesthesia. Moreover, the results showed that the most common anxieties resulted from the operation, waiting for surgery, not knowing what is happening, postoperative pain, awareness during anesthesia, and not awakening from anesthesia. Conclusions: APAIS and VAS-A provided a quantitative assessment of anxiety and a specific qualitative questionnaire for preoperative anxiety in cardiac surgery. According to the results, preoperative LoS > 2 days and lack of information related to surgery were the risk factors for high anxiety levels.

    Nosocomial urinary tract infection (UTI) increases hospitalization, cost and morbidity. In this cohort study, we aimed to determine the incidence, risk factors, etiology and outcomes of UTIs in post-operative cardiac children. To this end, we studied all post-operative patients admitted to the Pediatric Cardiac Intensive Care Unit (PCICU) in 2012, and we divided the patients into two groups: the UTI (UTI group) and the non-UTI (control group). We compared both groups for multiple peri-operative risk factors. We included 413 children in this study. Of these, 29 (7%) had UTIs after cardiac surgery (UTI group), and 384 (93%) were free from UTIs (control group). All UTI cases were catheter-associated UTIs (CAUTIs). A total of 1578 urinary catheter days were assessed in this study, with a CAUTI density rate of 18 per 1000 catheter days. Multivariate logistic regression analysis demonstrated the following risk factors for CAUTI development: duration of urinary catheter placement (pcongenital abnormalities of kidney and urinary tract (CAKUT) (purinary catheter, the presence of CAKUT, and the presence of syndromes comprised the main risk factors for CAUTI. Gram-negative organisms were the main causes for CAUTI, and one-third of them found to be resistant in this single-center study. PMID:26829892

    Full Text Available Human platelets express Toll-like receptors (TLR 4. However, the mechanism by which TLR4 directly affects platelet aggregation and blood coagulation remains to be explored. Therefore, in this study, we evaluated the platelet TLR4 expression in patients who underwent CABG surgery; we explored the correlation between platelet TLR4 expression and the early outcomes in hospital of patients. Additionally, C57BL/6 and C57BL/6-TlrLPS−/− mice were used to explore the roles of platelet TLR4 in coagulation by platelet aggregometry and rotation thromboelastometry. In conclusion, our results highlight the important roles of TLR4 in blood coagulation and platelet function. Of clinical relevance, we also explored novel roles for platelet TLR4 that are associated with early outcomes in cardiac surgery.

    To assess the incidence of and risk factors for acute adverse drug reactions (ADRs) (occurring within 1 h) following iopromide administration in cardiac catheterization in Chinese 'real-world' practice. Acute ADRs following iopromide administration during coronary angiography or percutaneous coronary intervention (PCI) have not been systematically evaluated in China. TRUST was a prospective, multicenter, observational study conducted at 63 centers in China. Patients received iopromide (300 or 370 mgI/mL) during coronary angiography or PCI (n = 17,513). Acute ADRs occurred in 66 patients (0.38%); ADRs were mild in 58 patients (0.33%) and severe in two patients (0.01%). Most acute ADRs manifested as allergy-like symptoms such as nausea/vomiting [39 patients (0.22%)] and/or rash [15 patients (0.09%)]. The rate of acute ADRs was lower among patients who received premedication (6/3349; 0.18 %) than those who did not (60/14,164; 0.42%; p = 0.0379), and among those who did receive pre-procedural hydration (10/7993; 0.13%) compared with those who did not (56/9520; 0.59%; p contrast media increased the risk of ADRs, while premedication with corticosteroids, pre-procedural hydration and contrast volume Contrast quality was rated as 'Excellent' in 99.1% of patients. The incidence of acute ADRs was very low with iopromide in cardiac catheterization in China. The risk of acute ADRs increased in patients contrast media. Premedication with corticosteroids and pre-procedural hydration may prevent acute ADRs in at-risk patients. PMID:26058857

    Full Text Available Aims and Objectives: To validate European system for cardiac operative risk evaluation II (EuroSCORE II and Society of Thoracic Surgeons (STS risk-score for predicting mortality and STS risk-score for predicting morbidity in Indian patients after cardiac surgery. Materials and Methods: EuroSCORE II and STS risk-scores were obtained pre-operatively for 498 consecutive patients. The patients were followed for mortality and various morbidities. The calibration of the scoring systems was assessed using Hosmer-Lemeshow test. The discriminative capacity was estimated by area under receiver operating characteristic (ROC curves. Results: The mortality was 1.6%. For EuroSCORE II and STS risk-score C-statics of 5.43 and 6.11 were obtained indicating satisfactory model fit for both the scores. Area under ROC was 0.69 and 0.65 for EuroSCORE II and STS risk-score with P values of 0.068 and 0.15, respectively, indicating poor discriminatory power. Good fit and discrimination was obtained for renal failure, long-stay in hospital, prolonged ventilator support and deep sternal wound infection but the scores failed in predicting risk of reoperation and stroke. Mortality risk was correctly estimated in low ( 5% patients by both scoring systems. Conclusions: EuroSCORE II and STS risk-scores have satisfactory calibration power in Indian patients but their discriminatory power is poor. Mortality risk was over-estimated by both the scoring systems in high-risk patients. The present study highlights the need for forming a national database and formulating risk stratification tools to provide better quality care to cardiac surgical patients in India.

    OBJECTIVE: To determine whether near infrared spectroscopic measurement of tissue pH and Po2 has sufficient accuracy to assess variation in tissue perfusion resulting from changes in blood pressure and metabolic demand during cardiopulmonary bypass. DESIGN: Prospective clinical study. SETTING: Academic medical center. SUBJECTS: Eighteen elective cardiac surgical patients. INTERVENTION: Cardiac surgery under cardiopulmonary bypass. MEASUREMENTS AND MAIN RESULTS: A near infrared spectroscopic fiber optic probe was placed over the hypothenar eminence. Reference Po2 and pH sensors were inserted in the abductor digiti minimi (V). Data were collected every 30 secs during surgery and for 6 hrs following cardiopulmonary bypass. Calibration equations developed from one third of the data were used with the remaining data to investigate sensitivity of the near infrared spectroscopic measurement to physiologic changes resulting from cardiopulmonary bypass. Near infrared spectroscopic and reference pH and Po2 measurements were compared for each subject using standard error of prediction. Near infrared spectroscopic pH and Po2 at baseline were compared with values during cardiopulmonary bypass just before rewarming commenced (hypotensive, hypothermic), after rewarming (hypotensive, normothermic) just before discontinuation of cardiopulmonary bypass, and at 6 hrs following cardiopulmonary bypass (normotensive, normothermic) using mixed-model analysis of variance. Near infrared spectroscopic pH and Po2 were well correlated with the invasive measurement of pH (R2 =.84) and Po2 (R 2 =.66) with an average standard error of prediction of 0.022 +/- 0.008 pH units and 6 +/- 3 mm Hg, respectively. The average difference between the invasive and near infrared spectroscopic measurement was near zero for both the pH and Po2 measurements. Near infrared spectroscopic Po2 significantly decreased 50% on initiation of cardiopulmonary bypass and remained depressed throughout the bypass and

MÉTODO: Treinta y dos niños, con edad entre 1 mes y 10 años, citados para cirugía cardíaca con circulación extracorpórea, que fueron distribuidos aleatoriamente en dos grupos: el Grupo MDZ recibió midazolam 0,2 mg.kg-1.h-1, mientras que el Grupo DEX recibió dexmedetomidina 1 µg.kg-1.h-1 durante una hora y enseguida el ritmo de infusión se redujo a la mitad en los dos grupos. Los dos grupos recibieron fentanil 10 µg. kg-1, midazolam 0,2 mg.h-1 y vecuronio 0,2 mg.kg-1 para la inducción de la anestesia. Las mismas dosis de fentanil con vecuronio de la inducción fueron infundidas durante la primera hora después de la inducción y enseguida reducidas a la mitad. Las infusiones fueron iniciadas inmediatamente después de la inducción y mantenidas hasta el final de la cirugía. El isoflurano se administró por un corto tiempo para el control de la respuesta hiperdinámica a la incisión y esternotomía. RESULTADOS: En los dos grupos, la presión arterial sistólica y la frecuencia cardíaca se redujeron ostensiblemente después de una hora de infusión anestésica, pero el aumento de la presión arterial sistólica y diastólica y el de la frecuencia cardíaca al momento de la incisión de la piel, fueron significantemente menores en el Grupo DEX. Un número significativamente menor de pacientes exigió un suplemento con isoflurano en el Grupo DEX. Después de la CEC, los pacientes de los dos grupos tuvieron respuestas hedominámicas similares. CONCLUSIONES: La infusión sin bolo de dexmedetomidina parece ser un adyuvante efectivo del fentanil en la promoción de la sedación y el control de las respuestas hemodinámicas durante la cirugía para las cardiopatías congénitas en niños.BACKGROUND AND OBJECTIVES: To evaluate the efficacy of the combined infusion of dexmedetomidine and fentanyl on the hemodynamic response during cardiac surgery with cardiopulmonary bypass (CPB in children.

    A 53-year-old male patient with severe chronic heart failure due to ischemic cardiomyopathy (LVEF 25%) awaiting heart transplantation was admitted for resection of a bladder tumor. The patient underwent implantation of a Chronicle implantable hemodynamic monitor (IHM) two years before. Thus, perioperative monitoring of heart rate, right ventricular systolic, diastolic and pulse pressure, dP/dt and estimated pulmonary artery diastolic pressure through a lead implanted in the right ventricle was performed. In the postoperative period the patient developed low-output syndrome requiring catecholamine treatment. The patient was weaned from mechanical ventilation uneventfully the same day. However, he developed symptomatic and hemodynamic worsening of heart failure shortly after reduction of inotropes and required prolonged medical treatment with catecholamines. Patients with cardiac disease are known to be at increased risk for cardiovascular complications after noncardiac surgery. Therefore, it has been suggested that such patients could potentially benefit from perioperative invasive hemodynamic monitoring. For the first time, we report a case of perioperative continuous hemodynamic monitoring with a long term-implanted device in a potential heart transplant patient. PMID:15568151

    For the quantification of cardiac {sup 123}I-metaiodobenzylguanidine (MIBG) uptake, the mediastinum is commonly used as a reference region reflecting nonspecific background activity. However, variations in the quantity of vascular structures in the mediastinum and the rate of renal clearance of {sup 123}I-MIBG from the blood pool may contribute to increased interindividual variation in uptake. This study examined the relationship between changes in heart (H) and mediastinal (M) counts and the change in vascular {sup 123}I-MIBG activity, including the effect of renal function. Fifty-one subjects with ischemic heart disease underwent early (15 min) and late (4 h) anterior planar images of the chest following injection of {sup 123}I-MIBG. Vascular {sup 123}I-MIBG activity was determined from venous blood samples obtained at 2 min, 15 min, 35 min, and 4 h post-injection. From the vascular clearance curve of each subject, the mean blood counts/min per ml at the time of each acquisition and the slope of the clearance curve were determined. Renal function was expressed as the estimated creatinine clearance (e-CC) and the estimated glomerular filtration rate (e-GFR). Relations between H and M region of interest (ROI) counts/pixel, vascular activity, and renal function were then examined using linear regression. Changes in ROI activity ratios between early and late planar images could not be explained by blood activity, the slope of the vascular clearance curves, or estimates of renal function. At most 3% of the variation in image counts could be explained by changes in vascular activity (p = 0.104). The e-CC and e-GFR could at best explain approximately 1.5% of the variation in the slopes of the vascular clearance curve (p = 0.194). The change in measured H and M counts between early and late planar {sup 123}I-MIBG images is unrelated to intravascular levels of the radiopharmaceutical. This suggests that changes in M counts are primarily due to decrease in soft tissue

    Full Text Available Several protective measures have been described to prevent contrast-induced nephropathy (CIN. This study is aimed to evaluate the effect of a high dose of N-acetylcysteine (NAC plus hydration, a low dose of NAC plus ascorbic acid and hydration or hydration alone on the prevention of CIN in high-risk patients undergoing elective coronary artery intervention. We conducted a randomized, prospective, placebo-controlled trial of 105 high-risk patients undergoing elective cardiac catheterization. The patients were divided into three different groups: Group A (n = 30, NAC 1200 mg orally before angiography and 1200 mg orally twice daily for three doses along with good hydration; Group B (n = 30, NAC 600 mg before angiography and 600 mg orally twice daily for three doses plus ascorbic acid (3000 mg one dose before angiography and 2000 mg two doses after angiography and good hydration; and Group C (n = 45, hydration with 0.9% saline started just before contrast media injection and continued for 12 h at a rate 1.0 mL/kg/min after angiography or 0.5 mL/kg/h in cases with overt heart failure for 12 h. CIN was defined as an increase in serum creatinine of >25% of baseline or an absolute increase of 0.5 mg/dL above baseline after 48 h. The incidence of CIN was significantly lower in Group A (6.66% compared with Group B (16.66% or Group C (17.77%. The difference between Groups A and B and between Groups A and C was also highly significant (P = 0.001. In contrast, the difference between Groups B and C was not statistically significant (P = 0.37. Our study indicates that high doses of NAC plus hydration provide better protection against CIN than combination therapy of NAC and ascorbic acid plus hydration, or hydration alone.

    Objective: To investigate the effect of Shen-Fu (SF) injection on gastrointestinal tract injury and its potential mechanism. Methods: Thirty-eight patients undergoing elective open heart surgery were assigned to Group C (control group, n=18) and Group SF (n=20) randomly. In Group SF, the patients received intravenous injection of SF (0.5 ml/kg) at the beginning of the surgery followed by a continuous infusion of 100 ml SF (1.0 ml/kg) solution diluted by saline at a rate of 0.004 ml*Kg-1*min-1with a Grasby pump. The control group was injected with normal saline in the same volume. Gastric intramucosal pH (pHi), activity of blood diamine oxidase (DAO), and concentrations of blood LPS and IL-6 were measured before CPB (S0) and 1 h (S1) and 2 h (S2) after aortic declamping, respectively.Results: In Group C, pHi value was significantly lower at S1 and S2 than at S0 ( mean P<0.01) and blood DAO and concentrations of LPS and IL-6 were significantly higher at S1 and S2 than at S0 ( meanP<0.01). In Group SF, pHi was obviously lower at S1 and S2 than at S0 (P<0.05) but LPS and IL-6 levels and DAO were higher at S0 (mean P<0.05). Blood DAO and LPS level demonstrated significant negative correlations with pHi (mean P<0.01) while LPS concentration showed a positive correlation with blood DAO (P<0.01) and IL-6 concentration(P<0.05). At S1 and S2 after aortic declamping, the levels of pHi were higher in Group SF than in Group C (mean P<0.01 ) but DAO and LPS and IL-6 levels were significantly lower in Group SF than in Group C ( P<0.01).Conclusions: SF has a protective effect on gastrointestinal tract and can reduce inflammatory actions.

    Pre-existing cardiac disease contributes significantly to morbidity and mortality amongst patients undergoing non cardiac surgery. Patients with pre-existing cardiac disease or with risk factors for it, have as much as a 3.9% risk of suffering a major perioperative cardiac event (Lee et al 1999, Devereaux 2005). Furthermore, the incidence of perioperative myocardial infarction (MI) is increased 10 to 50 fold in patients with previous coronary events (Jassal 2008).

    Full Text Available OBJECTIVE: As almost any version of percutaneous nephrolithotomy (PCNL was safely and efficiently applied for adults as well as children without age being a limiting risk factor, the aim of the study was to compare the different characteristics as well as the efficacy, outcome, and safety of the pediatric and adult patients who had undergone mini-PCNL (MPCNL in a single institution. METHODS: We retrospective reviewed 331 renal units in children and 8537 renal units in adults that had undergone MPCNL for upper urinary tract stones between the years of 2000-2012. The safety, efficacy, and outcome were analyzed and compared. RESULTS: The children had a smaller stone size (2.3 vs. 3.1 cm but had smilar stone distribution (number and locations. The children required fewer percutaneous accesses, smaller nephrostomy tract, shorter operative time and less hemoglobin drop. The children also had higher initial stone free rate (SFR (80.4% vs. 78.6% after single session of MPCNL (p0.05. Both groups had low rate of high grade Clavien complications. There was no grade III, IV, V complications and no angiographic embolization required in pediatric group. One important caveat, children who required multiple percutaneous nephrostomy tracts had significant higher transfusion rate than in adults (18.8% vs. 4.5%, p = 0.007. CONCLUSIONS: This contemporary largest-scale analysis confirms that the stone-free rate in pediatric patients is at least as good as in adults without an increase of complication rates. However, multiple percutaneous nephrostomy tracts should be practiced with caution in children.

    Sensorimotor cortex plasticity induced by constraint-induced movement therapy (CIMT) in six children (10.2 ± 2.1 years old) with hemiplegic cerebral palsy (CP) was assessed by functional near-infrared spectroscopy (fNIRS). The activation laterality index and time-to-peak/duration during a finger tapping task were quantified before, immediately after, and six months after CIMT. Five age-matched healthy children (9.8 ± 1.3 years old) were also imaged at the same time points to provide comparative activation metrics for normal controls. In children with CP the activation time-to-peak/duration for all sensorimotor centers displayed significant normalization immediately after CIMT that persisted six months later. In contrast to this longer term improvement in localized activation response, the laterality index that depended on communication between sensorimotor centers improved immediately after CIMT, but relapsed six months later.

    Sudden death in the young is rare. About 25% of cases occur during sports. Most young people with sudden cardiac death (SCD) have underlying heart disease, with hypertrophic cardiomyopathy and coronary artery anomalies being commonest in most series. Arrhythmogenic right ventricular dysplasia and long QT syndrome are the most common primary arrhythmic causes of SCD. It is estimated that early cardiopulmonary resuscitation and widespread availability of automatic external defibrillators could prevent about a quarter of pediatric sudden deaths

    Full Text Available OBJECTIVE: to evaluate changes in the biochemical profile of children treated or being treated for moderate or severe stunting in a nutrition recovery and education center. METHODS: this was a retrospective longitudinal study of 263 children treated at this center between August of 2008 to August of 2011, aged 1 to 6 years, diagnosed with moderate (z-score of height-for-age [HAZ] < -2 or severe stunting (HAZ < -3. Data were collected on socioeconomic conditions, dietary habits, and biochemical changes, as well as height according to age. RESULTS: the nutritional intervention showed an increase in HAZ of children with moderate (0.51 ± 0.4, p = 0.001 and severe (0.91 ± 0.7, p = 0.001 stunting during the monitoring. Increased levels of insulin-like growth factor 1 (IGF-1 (initial: 71.7 ng/dL; final: 90.4 ng/dL; p = 0.01 were also observed, as well as a reduction in triglycerides (TG in both severely (initial: 91.8 mg/dL; final: 79.1 mg/dL; p = 0.01 and in moderately malnourished children (initial: 109.2 mg/dL; final 88.7 mg/dL; p = 0.01, and a significant increase in high-density lipoprotein cholesterol HDL-C only in the third year of intervention (initial: 31.4 mg/dL; final: 42.2 mg/dL. The values of total cholesterol (TC and low-density lipoprotein cholesterol (LDL-C levels remained high throughout the treatment (initial: 165.1 mg/dL; final: 163.5 mg/dL and initial: 109.0 mg/dL; final: 107.3 mg/dL, respectively. CONCLUSION: the nutritional treatment for children with short stature was effective in reducing stunting and improving TG and HDL-C after three years of intervention. However, the levels of LDL-C and TC remained high even in treated children. It is therefore speculated that these changes may result from metabolic programming due to malnutrition.

    Full Text Available BACKGROUND Wound infiltration with local anaesthetics may improve postoperative analgesia and has become increasingly common. It has the ability to reduce the need for opioids, additional complications, duration of hospital stay and its provision of effective postoperative analgesia. Tramadol infiltration of wound has been shown to have effects similar to those of local anaesthetics. AIMS AND OBJECTIVES To investigate the effects of wound infiltration with levobupivacaine and tramadol on postoperative analgesia in children undergoing elective unilateral inguinal hernia and undescended testis surgery. METHODS Ninety children (Age Group 1 to 7 years who were scheduled to undergo elective unilateral inguinal hernia and undescended testis surgery were included in the study. Patients were allocated to 3 groups of 30 each: Group A received wound infiltration with 2 mg/kg Tramadol in 0.2 mL/kg saline, Group B received wound infiltration with 0.2 mL/kg of 0.25% Levobupivacaine and Group C received wound infiltration with 2 mg/kg Tramadol plus 0.25% Levobupivacaine (total volume of solution as 0.2 mL/kg. Pain score was assessed using FACES pain scale at 1, 4, 8, 12 and 24 hours postoperatively. Patients with pain score of ≥4 were treated with paracetamol suppository (20 mg/kg body weight as rescue analgesia. Respiratory rate and pulse rate were also recorded at 1, 4, 8, 12 and 24 hours postoperatively. The frequency of side effects and rescue analgesic used were also recorded during the 24-hour postoperative period. RESULTS Average pain scores, respiratory rate and pulse rate were lowest in Group C compared to Group A and Group B at 1, 4, 8, 12 and 24 hours postoperatively (P value of 0.05. CONCLUSION Infiltration of the wound site with combined Levobupivacaine and Tramadol provides significantly better analgesia compared with Levobupivacaine or Tramadol alone.

    Human immunodeficiency virus (HIV) infection causes dysfunction of different organ systems. Myocardial diastolic dysfunction has been reported previously in an adult HIV population. Our aim was to study myocardial strain in children and young adults infected by HIV who have apparently normal ejection fraction. Forty HIV-infected patients (mean age 20.6 ± 1.5 years) with normal ejection fraction and 55 matched normal controls (mean age 17 ± 1.5 years) were studied by two-dimensional echocardiogram. The images were stored then exported to velocity vector imaging software for analysis. Measures considered were left-ventricular peak global systolic strain (LV S) and strain rate (LV SR) as well as right-ventricular peak global systolic strain (RV S) and strain rate (RV SR). Circumferential measures of the left ventricle included the following: LV circumferential peak global systolic strain (LV circ S), strain rate (LV circ SR), radial velocity (LV rad vel), and rotational velocity (LV rot vel) at the level of the mitral valve. Statistical significance was set at p strain and strain rate in children and young adults. Normal ejection fraction might be attributed to preserved circumferential myocardial deformation. Strain and strain rate may help identify HIV patients at high risk for cardiac dysfunction and allow early detection of silent myocardial depression.

    Full Text Available Anesthesiologists are confronted with an increasing population of patients undergoing noncardiac surgery who are at risk for cardiac complications in the perioperative period. Perioperative cardiac complications are responsible for significant mortality and morbidity. The aim of the present study was to determine the incidence of perioperative (operative and postoperative cardiac complications and correlations between the incidence of perioperative cardiac complications and type of surgical procedure, age, presence of concurrent diseases. A total of 100 patients with cardiac diseases undergoing noncardiac surgery were included in the prospective study (Group A 50 patients undergoing intraperitoneal surgery and Group B 50 patients undergoing breast and thyroid surgery. The patients were followed up during the perioperative period and after surgery until leaving hospital to assess the occurrence of cardiac events. Cardiac complications (systemic arterial hypertension, systemic arterial hypotension, abnormalities of cardiac conduction and cardiac rhythm, perioperative myocardial ischemia and acute myocardial infarction occurred in 64% of the patients. One of the 100 patients (1% had postoperative myocardial infarction which was fatal. Systemic arterial hypertension occurred in 57% of patients intraoperatively and 33% postoperatively, abnormalities of cardiac rhythm in 31% of patients intraoperatively and 17% postoperatively, perioperative myocardial ischemia in 23% of patients intraoperatively and 11% of postoperatively. The most often cardiac complications were systemic arterial hypertension, abnormalities of cardiac rhythm and perioperative myocardial ischemia. Factors independently associated with the incidence of cardiac complications included the type of surgical procedure, advanced age, duration of anaesthesia and surgery, abnormal preoperative electrocardiogram, abnormal preoperative chest radiography and diabetes.

    Full Text Available Purpose: General anaesthesia for oral surgeries in paediatric patients is always challenging for an anaesthesiologist. Aim was to compare halothane+propofol and sevoflurane+propofol in paediatric patients undergoing adenotonsillectomy without muscle relaxant. Method: In a double blind manner, eighty patients of 3-10 years were premedicated with inj. Atropine and randomly divided into two groups of forty each. In Group A, priming was done with 50% oxygen+50% nitrous oxide+4% halothane for 1 minute, after loss of eye lash reflex and centralisation of pupil intravenous cannulation done. Inj. midazolom, lignocaine and Propofol were given and trachea was intubated. Maintenance was done with 1-2% halothane+ nitrous oxide+ oxygen and continuous propofol infusion. Similar technique was used in group B except for priming done with sevoflurane 7% and maintenance with 2-3%. Both groups were compared for induction, intubating conditions, haemodynamics and emergence characteristics. Results: Induction was rapid in group B as time for loss of eye lash reflex and centralisation of pupil was less in group B (21.88±12.6 &114.40±28.8 seconds as compared to group A (33.05±4.0 & 140.05±12.1 sec p<0.001. Intubating conditions were excellent but mean intubation time was less in group B as compared to group A p<0.001. Heart rate and blood pressure remained on lower side in group A. Emergence was significantly rapid in group B. No side effect or complications were noted. Conclusion: Both groups provided excellent intubating conditions but sevoflurane+propofol group was better as it provided faster induction and rapid recovery from anaesthesia with more stable haemodynamics as compared to Halothane+propofol group.

    Full Text Available Introduction: Hearing is one of the premier human senses. Being deprived from hearing is not only being unable to hear the sounds, but it is also the disability to gain a lot of helpful experiences. Cochlear implantation is introduced worldwide in order to treat the severe to profound hearing loss. Therefore, the present study aims to determine the effect of age of cochlear implantation on improvement of the auditory performance. Methods: The present follow-up study was conducted on 96 children who had referred to Fars Cochlear Implantation Center. The patients’ information was gathered from their profiles both before and after the operation. In addition, the auditory performance score was obtained in 3 stages – 6 months, 1 year, and 2 years after the implantation – through the Cap test. Also, non-parametric tests of Fridman, Willcoxon, and Mann-Withney U were utilized in order to analyze the data of the study. Results: The mean of the children’s auditory performance 6 months, 1 year, and 2 years after the implantation was measured as 2.8+1.03, 4.36+1.04, and 5.34+1.02, respectively. Besides, the median of their auditory performance 6 months, 1 year, and 2 years after the implantation was calculated as 3, 5, and 5, respectively. Also, a statistically significant relationship was observed between the independent variable of age of cochlear implantation and the auditory performance score 6 months, 1 year, and 2 years after the implantation. Conclusion: In line with other studies conducted on the issue, the present study showed the improvement of the auditory performance in the children who benefited from cochlear implantation. Moreover, the results of the present study revealed that the age of cochlear implantation can be of great help in determining the candidates of cochlear implantation. In other words, it can be a major prognostic factor of the response to the treatment

    Objective: The purpose of this study was to compare the diagnostic accuracy of 64-slice CT with that of invasive angiography in the detection of graft and/or coronary angioplasty stenosis in children who had undergone coronary artery surgery. Population and methods: Fifteen consecutive children (8 male and 7 female; age 9.2 {+-} 6.1 years) underwent 64-slice CT because of chest pain or ECG changes mean 4.8 {+-} 3.7 years after surgical coronary artery surgery; 10 patients had coronary angioplasty using a patch from the saphenous vein, four had mammary artery bypass, and one had saphenous vein bypass. Six main segments of the coronary arteries and all the bypass graft considered as a single segment were analyzed and compared with invasive angiography used as the reference standard. Results: CT correctly identified the four children with coronary angioplasty and mammary graft lesions that were confirmed by conventional angiography: one patient had a significant stenosis (>50% stenosis) at the mammary bypass graft anastomosis site; three other had non-significant stenosis (<50% stenosis) including a mild lesion of the saphenous vein patch in two patients and a mild lesion at the anastomosis site of the mammary bypass in one. All segments identified as normal by CT in the other 11 children were also found to be normal by conventional angiography. Conclusion: In centers expert in this technique, 64-slice CT scanning is a promising, rapid, and useful diagnostic technique for evaluating both coronary angioplasty and bypass graft lesions in children who had undergone coronary artery surge0008.

    Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis and Staphylococcus aureus colonization of the adenoids and nasopharynx in 103 preschool children who underwent adenoidectomy for recurrent upper respiratory tract infections was examined. Bacterial interactions and risk factors for bacterial colonization of the nasopharynx and adenoids, separately, were analysed statistically. The prevalence of simultaneous isolation from both anatomical sites was 45·6% for S. pneumoniae, 29·1% for H. influenzae, 15·5% for M. catarrhalis and 18·4% for S. aureus. Three pathogens were significantly more frequent together from adenoid samples; nasopharyngeal swabs more often yielded a single organism, but without statistical significance. M. catarrhalis and S. aureus significantly more frequently co-existed with S. pneumoniae and H. influenzae than with each other and a positive association of S. pneumoniae and H. influenzae in adenoid samples was evident. Several differences between risk factors for nasopharyngeal and adenoid colonization by the individual pathogens were observed. We conclude that the adenoids and nasopharynx appear to differ substantially in colonization by pathogenic microbes but occurrence of H. influenzae and S. pneumoniae in the nasopharynx could be predictive of upper respiratory tract infections.

    Several minimally-invasive technologies are available for cardiac output (CO) measurement in children, but the accuracy and precision of these devices have not yet been evaluated in a systematic review and meta-analysis. We conducted a comprehensive search of the medical literature in PubMed, Cochrane Library of Clinical Trials, Scopus, and Web of Science from its inception to June 2014 assessing the accuracy and precision of all minimally-invasive CO monitoring systems used in children when compared with CO monitoring reference methods. Pooled mean bias, standard deviation, and mean percentage error of included studies were calculated using a random-effects model. The inter-study heterogeneity was also assessed using an I(2) statistic. A total of 20 studies (624 patients) were included. The overall random-effects pooled bias, and mean percentage error were 0.13 ± 0.44 l min(-1) and 29.1 %, respectively. Significant inter-study heterogeneity was detected (P residual heterogeneity remained after conducting sensitivity and subgroup analyses based on the various study characteristics. By meta-regression analysis, we found no independent effects of study characteristics on weighted mean difference between reference and tested methods. Although the pooled bias was small, the mean pooled percentage error was in the gray zone of clinical applicability. In the sub-group analysis, electrical cardiometry was the device that provided the most accurate measurement. However, a high heterogeneity between studies was found, likely due to a wide range of study characteristics. PMID:26315477

    Full Text Available BACKGROUND: The effects of physical therapy on heart rate variability (HRV, especially in children, are still inconclusive. OBJECTIVE: We investigated the effects of conventional physical therapy (CPT for airway clearance and nasotracheal suction on the HRV of pediatric patients with acute bronchiolitis. METHOD: 24 children were divided into two groups: control group (CG, n=12 without respiratory diseases and acute bronchiolitis group (BG, n=12. The heart rate was recorded in the BG at four different moments: basal recording (30 minutes, 5 minutes after the CPT (10 minutes, 5 minutes after nasotracheal suction (10 minutes, and 40 minutes after nasotracheal suction (30 minutes. The CG was subjected to the same protocol, except for nasotracheal suction. To assess the HRV, we used spectrum analysis, which decomposes the heart rate oscillations into frequency bands: low frequency (LF=0.04-0.15Hz, which corresponds mainly to sympathetic modulation; and high frequency (HF=0.15-1.2Hz, corresponding to vagal modulation. RESULTS: Under baseline conditions, the BG showed higher values in LF oscillations, lower values in HF oscillations, and increased LF/HF ratio when compared to the CG. After CPT, the values for HRV in the BG were similar to those observed in the CG during basal recording. Five minutes after nasotracheal suction, the BG showed a decrease in LF and HF oscillations; however, after 40 minutes, the values were similar to those observed after application of CPT. CONCLUSIONS: The CPT and nasotracheal suction, both used for airway clearance, promote improvement in autonomic modulation of HRV in children with acute bronchiolitis.

    Full Text Available Introduction: Human immunodeficiency virus (HIV infection is a primary cause of acquired heart disease, particularly of accelerated atherosclerosis, symptomatic heart failure, and pulmonary arterial hypertension. Cardiac complications often occur in late-stage HIV infections as prolonged viral infection is becoming more relevant as longevity improves. Thus, multi-agent HIV therapies that help sustain life may also increase the risk of cardiovascular events and accelerated atherosclerosis. Discussion: Before highly active antiretroviral therapy (HAART, the two-to-five-year incidence of symptomatic heart failure ranged from 4 to 28% in HIV patients. Patients both before and after HAART also frequently have asymptomatic abnormalities in cardiovascular structure. Echocardiographic measurements indicate left ventricular (LV systolic dysfunction in 18%, LV hypertrophy in 6.5%, and left atrial dilation in 40% of patients followed on HAART therapy. Diastolic dysfunction is also common in long-term survivors of HIV infection. Accelerated atherosclerosis has been found in HIV-infected young adults and children without traditional coronary risk factors. Infective endocarditis, although rare in children, has high mortality in late-stage AIDS patients with poor nutritional status and severely compromised immune systems. Although lymphomas have been found in HIV-infected children, the incidence is low and cardiac malignancy is rare. Rates of congenital cardiovascular malformations range from 5.6 to 8.9% in cohorts of HIV-uninfected and HIV-infected children with HIV-infected mothers. In non-HIV-infected infants born to HIV-infected mothers, foetal exposure to ART is associated with reduced LV dimension, LV mass, and septal wall thickness and with higher LV fractional shortening and contractility during the first two years of life. Conclusions: Routine, systematic, and comprehensive cardiac evaluation, including a thorough history and directed laboratory

    Objective: To study the correlation of low-dose 64-row multi-detector computed tomography (MDCT) with echocardiography and cardiac catheterization angiography (CCA) in the assessment of pulmonary arterial anatomy in children with cyanotic congenital heart disease (CCHD). Materials and methods: This prospective study included 105 children (74 males, 31 females) with CCHD, in the age group of 2 months to 20 years, who underwent 64-row MDCT examination (low-dose CT protocol), echocardiography and CCA for the assessment of pulmonary arteries, including visualization, presence of confluence, stenosis and collaterals. Statistical analysis was performed using the non-parametric statistical analysis test to evaluate the concordance or discordance between echocardiography, MDCT and CCA. Results: 64-row MDCT detected significantly more main and branch pulmonary arteries, patent pulmonary confluences, and more cases of pulmonary artery stenosis. CCA detected more major aorto-pulmonary collaterals than MDCT, whereas echocardiography failed to identify these major aorto-pulmonary collaterals. The effective CT radiation dose to patients less than 2 years of age was in the range of 0.7–2.5 mSv, where as the dose in patients more than 2 years of age ranged from that of 2.1 to 4.2 mSv, which is much less than the radiation dose reported in cardiac catheterization angiography. Conclusion: In cases where cardiac MRI cannot be performed, or is not sufficiently informative, low-dose 64-row MDCT correlates well with CCA and can provide adequate information about pulmonary arterial anatomy in children with cyanotic congenital heart disease, and can replace invasive cardiac catheterization angiography with markedly reduced radiation dosage to the patient.

    Full Text Available Background: The aim of this study was to compare the intravenous (IV and caudal routes of administration of sufentanil for children undergoing orchidopexy and also to evaluate the effects on addition of caudal adrenaline and neostigmine. Materials and Methods: Sixty patients scheduled for orchidopexy were divided into the following groups: 1 Group IVSu received IV 0.5 μg/kg sufentanil and caudal saline; 2 Group CSu received caudal 0.5 μg/kg sufentanil and IV saline; 3 Group CSuAdr received caudal sufentanil plus adrenaline 5 μg/ml (1:200,000 and IV saline; 4 Group CSuNeo received caudal sufentanil plus neostigmine, and IV saline; and 5 Group CSuNeoAdr received caudal sufentanil plus neostigmine plus adrenaline, and IV saline. Heart rate and mean blood pressure >15% was treated with increasing isoflurane concentration. Consumption of isoflurane, side effects, quality of sleep, time to first administration of analgesic, and number of doses of 24-h rescue analgesic were recorded. Results: Groups were demographically similar. Isoflurane consumption showed the following association: Group IVSu = Group CSuNeo = Group CSuNeoAdr Group CSuNeo = Group CSuNeoAdr (P < 0.005. Incidence of adverse effects was similar among groups. Conclusion: Caudal sufentanil alone was no better than when administered in the IV route, and would just be justified by the association of neostigmine, but not adrenaline. Neostigmine association resulted in better perioperative analgesia.

    Full Text Available The Coronary Artery Risk Detection In Appalachian Communities (CARDIAC Project has screened more than 80,000 children (10–12 years for cardiovascular and diabetes risk factors over the past 15 years. Simultaneous referral and intervention efforts have also contributed to the overall program impact. In this study, we examined evidence of programmatic impact in the past decade at the individual, family, community, and policy levels from child screening outcomes, referral rates, participation in subsequent services, and policies that embed the activities of the project as a significant element. Within this period of time, fifth-grade overweight and obesity rates were maintained at a time when rates elsewhere increased. 107 children were referred for additional screening and treatment for probable familial hypercholesterolemia (FH; 82 family members were subsequently screened in family-based screening efforts. 58 grants were distributed throughout the state for community-appropriate obesity intervention. A state wellness policy embedded CARDIAC as the method of assessment and national child cholesterol screening guidelines were impacted by CARDIAC findings. The sustainability and successful impact of this school-based program within a largely underserved, rural Appalachian state are also discussed.

  13. Introduction to cardiac imaging in infants and children: Techniques, potential, and role in the imaging work-up of various cardiac malformations and other pediatric heart conditions

    International Nuclear Information System (INIS)

    The increasing prevalence of congenital heart disease (CHD) can be attributed to major improvements in diagnosis and treatment. Although echocardiography is the most commonly used imaging modality for diagnosis and follow-up of subjects with CHD, the evolution of cardiovascular magnetic resonance (MR) imaging and increasingly computed tomography (CT) does offer new ways to visualize the heart and the great vessels. The development of cardiovascular MR techniques allows for a comprehensive assessment of cardiac anatomy and function. This provides information about the long-term sequlae of the underlying complex anatomy, hemodynamic assessment of residual post-operative lesions and complications of surgery. As much of the functional data in CHD patients is usually acquired with invasive X-ray angiography, non-invasive alternatives such as cardiovascular MR (and CT) are desirable. This review evaluates the role of MR imaging in the management of subjects with CHD, particularly detailing recent developments in imaging techniques as they relate to the various CHD diagnoses we commonly encounter in our practice

    Full Text Available BACKGROUND: There is a relative lack of studies on postoperative changes in nitrite (NO2 - concentrations, a marker of injury, following cardiac surgery. In this context, investigations on how exhaled NO concentrations vary in the postoperative period of cardiac surgery will certainly contribute to new clinical findings. OBJECTIVE: The objective of this study was to compare the EBC NO levels in both the pre and postoperative (24 hours periods of cardiac surgery. METHODS: Twenty - eight individuals were divided into three groups: 1 control, 2 coronary artery bypass grafting, and 3 valve surgery. The nitrite (NO2 - levels were measured by chemiluminescence in blood samples and exhaled breath condensate (EBC. Data were analyzed by the Mann - Whitney and Wilcoxon tests. RESULTS: 1 Preoperatively, the EBC NO2 - levels from groups 2 and 3 patients were higher than control individuals; 2 The postoperative (24 hours NO2 - levels in the EBC from group 3 patients were lower compared with preoperative values; 3 The NO2 - levels in the plasma from group 2 patients were lower in the preoperative compared with the postoperative (24h values and; 4 Preoperatively, there was no difference between groups 2 and 3 in terms of plasma NO2 - concentrations. CONCLUSION: These data suggest that NO measurement in EBC is feasible in cardiac surgery patients.INTRODUÇÃO: Estudos mostrando alterações das concentrações de nitrito (NO2 - exalado, com biomarcador de lesão, são raros em pacientes submetidos à cirurgia cardíaca.

    Left ventricular (LV) mechanical dyssynchrony (LVMD) was assessed by gated single-photon emission CT myocardial perfusion imaging (MPI) as an independent predictor of death from any cause in patients with known coronary artery disease (CAD) and reduced LV function. Between 2001 and 2010, 135 patients (64 {+-} 11 years of age, 84 % men) with known CAD, reduced LV ejection fraction (LVEF, 38 {+-} 15 %) and without an implanted cardiac resynchronization therapy device underwent gated MPI at rest. LV functional evaluation, which included phase analysis, was conducted to identify patients with LVMD. Kaplan-Meier survival curves were calculated for death of any cause during a mean follow-up of 2.0 {+-} 1.7 years. Uni- and multivariate Cox proportional hazards regression models were calculated to identify independent predictors of death from any cause. Of the 135 patients, 30 (22 %) died during follow-up (18 cardiac deaths and 12 deaths from other causes). Kaplan-Meier curves showed a significantly shorter survival time in the patients with severely reduced LVEF (<30 %, n = 45) or with LVMD (n = 81, log-rank test P <0.005). Cox models identified LVMD, LVEF <30 % and a total perfusion deficit at rest of {>=}20 % as independent predictors of death from any cause. While patients with LVEF <30 % in conjunction with LVMD had similar survival times irrespective of whether they had early revascularization or medical therapy, those patients with LVEF {>=}30% and LVMD who underwent revascularization had significantly longer survival. In patients with known CAD and reduced LV function, dyssynchrony of the LV is an independent predictor of death from any cause. (orig.)

    Full Text Available Objectives: To explore patients’ views on the EuroQol-5D and Coronary Revascularisation Outcome Questionnaire, tools currently used for collecting patient-reported outcome measures in the English National Health Service. The key questions were as follows: (1 whether patients consider them sensitive enough to detect change in their health after cardiovascular disease interventions and (2 whether they consider the health-related quality-of-life questions as meaningful. Methods: Data were collected on patients’ views using focus groups. We held four focus groups selecting participants on the basis of their baseline and follow-up EuroQol-5D scores. Data were analysed using framework analysis and grounded theory. Results: Focus group participants confirmed that they had derived substantial health benefits from their cardiac interventions despite the lack of measurable effects on the EuroQol-5D scores. Participants felt that the EuroQol-5D questionnaire was limited because of the following reasons: Their health fluctuates from day to day. They had difficulty assessing their general health status on the visual analogue scale. They felt that the Coronary Revascularisation Outcome Questionnaire was limited because of the following reasons: They did not understand the clinical terms used. The impact of tiredness on their quality of life was not captured. They were unable to distinguish between the effects of their heart condition and other health issues. Additionally, neither questionnaire considers the adjustments people have made to their domestic arrangements to improve their health-related quality of life. Conclusion: This study provides evidence that the two questionnaires do not capture some aspects of health that patients consider important. Furthermore, the presence of co-morbidities masks the symptoms relating to the heart disease and the effect of their cardiac interventions. Future work on patient-reported outcome measures should consider

    Cardiac Malposition refers to any position of the heart other than a left-sided heart in a situs solitus individual. Associated cardiac malformations are so complex that even angiocardiographic and autopsy studies may not afford an accurate information. Although the terms and classifications used to describe the internal cardiac anatomy and their arterial connections in cardiac malpositions differ and tend to be confusing, common agreement exists on the need for a segmental approach to diagnosis. Authors present 18 cases of cardiac malpositions in which cardiac catheterization and angiocardiography were done at the Department of Radiology, Seoul National University Hospital between 1971 and 1979. Authors analyzed the clinical, radiographic, operative and autopsy findings with the emphasis on the angiocardiographic findings. The results are as follows: 1. Among 18 cases with cardiac malpositions, 6 cases had dextrocardia with situs inversus, 9 cases had dextrocardia with situs solitus and 3 cases had levocardia with situs inversus. 2. There was no genuine exception to visceroatrial concordance rule. 3. Associated cardiac malpositions were variable and complex with a tendency of high association of transposition and double outlet varieties with dextrocardia in situs solitus and levocardia in situs inversus. Only one in 6 cases of dextrocardia with situs inversus had pure transposition. 4. In two cases associated pulmonary atresia was found at surgery which was not predicted by angiocardiography. 5. Because many of the associated complex lesions can be corrected surgically provided the diagnosis is accurate, the selective biplane angiocardiography with or without cineradiography is essential.

    International Nuclear Information System (INIS)

    The detriment, due to ionizing irradiation, ascribable to infants and children may be as high as three times that to adults. Recent interest in dose reduction, in part associated with the advent of the Diamentor dose-area product meter, has led to several studies reporting average dose-area products at a number of centres for micturating cystourethrograms (MCUGS) and other radiological examinations. In this review the data has been further processed to yield the ICRP 60 Equivalent Doses and a detriment factor applied to yield the numbers of infants and children likely to suffer detriment in future life as a result of having undergone the procedure at the centres reviewed.

  15. Effects of Radiation Exposure From Cardiac Imaging: How Good Are the Data?

    Science.gov (United States)

    Einstein, Andrew J.

    2012-01-01

    Concerns about medical exposure to ionizing radiation have become heightened in recent years due to rapid growth in procedure volumes and the high radiation doses incurred from some procedures. This article summarizes the evidence base undergirding concerns about radiation exposure in cardiac imaging. After classifying radiation effects, explaining terminology used to quantify the radiation received by patients, and describing typical doses from cardiac imaging procedures, I address the major epidemiological studies having bearing on radiation effects at doses comparable to those received by patients undergoing cardiac imaging. These include studies of atomic bomb survivors, nuclear industry workers, and children exposed in utero to x-rays, all of which have evidenced increased cancer risks at low doses. Additional higher dose epidemiological studies of cohorts exposed to radiation in the context of medical treatment are described and found to be generally compatible with these cardiac-dose-level studies, albeit with exceptions. Using risk projection models developed by the US National Academies that incorporate these data and reflect several evidence-based assumptions, cancer risk from cardiac imaging can be estimated and compared to benefits from imaging. Several ongoing epidemiological studies will provide better understanding of radiation-associated cancer risks. PMID:22300689

    Children with systemic Juvenile Idiopathic Arthritis (sJIA), the most severe subtype of JIA, are at risk from destructive polyarthritis and growth failure, and corticosteroids as part of conventional treatment can result in osteoporosis and growth delay. In children where there is failure or toxicity from drug therapies, disease has been successfully controlled by T-cell-depleted autologous stem cell transplantation (ASCT). At present, the immunological basis underlying remission after ASCT is unknown. Immune reconstitution of T cells, B cells, natural killer cells, natural killer T cells and monocytes, in parallel with T-cell receptor (TCR) diversity by analysis of the β variable region (TCRVb) complementarity determining region-3 (CDR3) using spectratyping and sequencing, were studied in five children with sJIA before and after ASCT. At time of follow up (mean 11.5 years), four patients remain in complete remission, while one child relapsed within 1 month of transplant. The CD8(+) TCRVb repertoire was highly oligoclonal early in immune reconstitution and re-emergence of pre-transplant TCRVb CDR3 dominant peaks was observed after transplant in certain TCRVb families. Further, re-emergence of pre-ASCT clonal sequences in addition to new sequences was identified after transplant. These results suggest that a chimeric TCR repertoire, comprising T-cell clones developed before and after transplant, can be associated with clinical remission from severe arthritis. PMID:24405357

    The I-123 MIBG cardiac scintigraphy can assess norepinephrine uptake. It has been shown that cardiac adrenergic neuronal function was impaired in adults with dilated cardiomyopathy. The aim of this prospective study was to assess cardiac neuronal function in children with idiopathic dilated cardiomyopathy (DCM) and to compare cardiac uptake of I-123 MIBG with left ventricular ejection fraction (LVEF). We studied 26 consecutive patients with idiopathic DCM, aged 44 {+-} 50 months, and 12 controls, aged 49 {+-}65 months. A planar scintigraphy was performed in all children 4 hours after intravenous injection of 20 to 75 MBq of I-123 MIBG. A static anterior view was acquired for 10 minutes. Cardiac uptake of I-123 MIBG was expressed as the heart to mediastinum count ratio (HMR). Equilibrium radionuclide angiography was performed following a standard protocol. Cardiac uptake of I-123 MIBG was significantly decreased in patients with idiopathic DCM when compared with cardiac uptake in controls (172{+-}34% vs 277{+-}14%, P<0.0001). There was a good correlation between RCM and LVEF in patients with idiopathic DCM (y = 2.5 x +113.3, r = 0.80, P < 0.0001). In conclusion, cardiac neuronal function was impaired in children with idiopathic DCM and related to impairment of left ventricular function. (author)

    Sensorimotor cortex plasticity induced by constraint-induced movement therapy (CIMT) in six children (10.2±2.1 years old) with hemiplegic cerebral palsy was assessed by functional near-infrared spectroscopy (fNIRS). The activation laterality index and time-to-peak/duration during a finger-tapping task and the resting-state functional connectivity were quantified before, immediately after, and 6 months after CIMT. These fNIRS-based metrics were used to help explain changes in clinical scores of manual performance obtained concurrently with imaging time points. Five age-matched healthy children (9.8±1.3 years old) were also imaged to provide comparative activation metrics for normal controls. Interestingly, the activation time-to-peak/duration for all sensorimotor centers displayed significant normalization immediately after CIMT that persisted 6 months later. In contrast to this improved localized activation response, the laterality index and resting-state connectivity metrics that depended on communication between sensorimotor centers improved immediately after CIMT, but relapsed 6 months later. In addition, for the subjects measured in this work, there was either a trade-off between improving unimanual versus bimanual performance when sensorimotor activation patterns normalized after CIMT, or an improvement occurred in both unimanual and bimanual performance but at the cost of very abnormal plastic changes in sensorimotor activity.

    Minimizing the systemic inflammatory response caused by cardiopulmonary bypass is a major concern. It has been suggested that the perfusion temperature affects the inflammatory response. The aim of this prospective study was to compare the effects of moderate hypothermia (32°C) and normothermia (36°C) during cardiopulmonary bypass on markers of the inflammatory response and clinical outcomes (time on ventilator) after surgical closure of ventricular septal defects. During surgical closure of ventricular septal defects under cardiopulmonary bypass, 20 children (median age 4.9 months, range 2.3-38 months; median weight 7.2 kg, range 5.2-11.7 kg) were randomized to a perfusion temperature of either 32°C (Group 1, n = 10) or 36°C (Group 2, n = 10). The clinical data and blood samples were collected before cardiopulmonary bypass, directly after aortic cross-clamp release, and 4 and 24 h after weaning from cardiopulmonary bypass. Time on ventilation as primary outcome did not differ between the two groups. Other clinical outcome parameters like fluid balance or length of stay in the intensive care were also similar in the two groups.

    Central anticholinergic syndrome (CAS) following general anesthesia (GA) is a well known syndrome in children and adults. Many cases of CAS have been previously reported in the literature. However, there are only two reports of post resuscitation CAS after administration of small doses of atropine. Hereby, we report a case of CAS in a child undergoing complete dental restoration under GA after receiving a small dose of atropine to reverse hypoxia induced bradycardia. Intraoperative events such as hypoxia or cardiac arrest may play a role as triggers for CAS. However, we cannot establish a causal relationship between the occurrence of CAS and such critical events.

    Full Text Available Ropivacaine having better safety profile and less motor blockade than bupivacaine is well suited for caudal analgesia. Since studies done regarding the effect of fentanyl and clonidine as adjuvants to ropivacaine for prolongation of caudal analgesia are scant and have shown conflicting results, the present study was conducted. METHODS: A total of 90 children aged between 3-6yrs belonging to ASA class I and II undergoing surgical procedures below the umbilicus were randomly allocated to one of two groups: Group R received ropivacaine 0.2%, 1 ml/kg with saline 0.02ml/kg and Group RF received ropivacaine 0.2%, 1 ml/kg with fentanyl 1 μg/kg (0.02ml/kg and Group RC (clonidine received 1ml/kg of 0.2% Ropivacaine plus clonidine 2µg / kg caudally after induction of general endotracheal anaesthesia. The pain score was evaluated using Hannallah pain scale, motor blockade using modified bromage scale and sedation assessed using 4 point sedation score at 30 minutes after extubation and at 1, 2, 4, 6, 12 and 24 h. The time to awakening, first analgesic requirement time, number of doses of rescue analgesic and side-effects in a 24 hours period were also recorded. The results were evaluated using SPSS 17 statistical method. RESULTS: There were no differences in demographic characteristics between the groups. However, mean duration of caudal analgesia was 659.5 minutes in group R, 784.5 minutes in group RF and 960.5 minutes in group RC which was statistically highly significant (P<0.01.The total dose of rescue analgesic in 24 hours was lower in groups RF and RC. Also the number of children receiving rescue analgesia at 12 hours was higher in placebo group than fentanyl group and clonidine group which was statistically highly significant (P<0.01. Increased incidence of urinary retention and pruritis was noted in group RF which was statistically not significant (P=0.366. CONCLUSION: Addition of inj.

    Full Text Available Background. Adipose tissue is an important endocrine organ that secretes cytokines, including adiponectin, levels of which are negatively correlated with the severity of the inflammatory process. Aim. To assess the time course of adiponectin levels following open heart surgery with cardiopulmonary bypass and its correlation with early postoperative outcomes. Materials and Methods. Blood samples were obtained from 24 children undergoing cardiac surgery and analyzed for adiponectin, C-reactive protein, and other inflammatory markers. Results. Baseline adiponectin levels were negatively correlated with patients’ preoperative weight and age. Postoperative adiponectin levels decreased compared to baseline ( and correlated negatively with duration of cardiopulmonary bypass (, , length of stay in the pediatric intensive care unit (, , and the inotropic score (, . Adiponectin levels were positively correlated with sVCAM 1 levels; however, there was no correlation between adiponectin levels and sP selectin, tPA, MCP1, and sCD40. Conclusions. The inflammatory response after open heart surgery with cardiopulmonary bypass is associated with a reduction in adiponectin levels. Prolonged or more complicated surgery induced a more substantial inflammatory process characterized by a significant reduction in adiponectin levels over time and a delayed return to baseline levels.

    Full Text Available Cardiac hydatid disease is rare. We report on an uncommon hydatid cyst localized in the right ventricular wall, right atrial wall tricuspid valve left atrium and pericard. A 33-year-old woman was treated for cough, fever and chest pain. Cardiac echocardiograpic examination revealed a round tumor (5.8 x 4 cm in the right ventricular free wall and two smaller cysts behind that tumor. There were cysts in right atrial wall and tricuspidal valve as well. Serologic tests for hydatidosis were positive. Computed tomography finding was consistent with diagnosis of hydatid cyst in lungs and right hylar part. Surgical treatment was rejected due to great risk of cardiac perforation. Medical treatment with albendazole was unsuccessful and the patient died due to systemic hydatid involvement of the lungs, liver and central nervous system.

    Bronchiolitis obliterans syndrome (BOS) is a devastating complication after allogeneic stem cell transplantation (allo-SCT). Early identification of high-risk patients is pivotal for success. Lung proteins, KL-6, CCSP, SP-A, and SP-D, measured in the serum may identify high-risk patients for BOS earlier than pulmonary function tests (PFTs) can identify changes or clinical symptoms. Lung proteins were measured in patients' serum at baseline and at 1, 3, 6, 9, 12, 18, and 24 months after transplantation along with history, clinical examination, and PFTs. Serum levels of lung proteins were also measured in healthy control subjects. The primary endpoint was the development of BOS confirmed by pathological biopsy or National Institutes of Health criteria. Between September 2009 and September 2011, 39 patients were enrolled. Six children developed BOS at a median time of 200 days (range, 94 to 282). KL-6 levels were low in control subjects, at a median of .1 U/mL (range, .1 to 1.5). Pre-SCT and 1-month KL-6 levels were significantly higher in surviving patients who developed BOS (n = 6) versus those who did not (n = 18) (pre-SCT: mean, 32.6 U/mL [IQR, 9.7 to 89.3] versus 5.8 U/mL [IQR, 2.1 to 12.6], P = .03; at 1 month: mean, 52.5 U/mL [IQR, 20.2 to 121.3] versus 11.4 U/mL [IQR, 5.7 to 36.0], P = .04). Three- and 6-month KL-6 levels continued to be higher in BOS group but were not statistically significant. CCSP, SP-A, and SP-D were not predictive. KL-6 measured in the serum of children receiving allo-SCT may identify patients at high risk for the development of BOS. These patients will benefit from intensive surveillance protocol and early therapy before irreversible lung damage. PMID:25963919

    Steroid-induced osteonecrosis (ON) is a challenging complication encountered during modern chemotherapy for childhood acute lymphoblastic leukemia (ALL). We retrospectively assessed the incidence of ON and its risk factors in a total of 1095 patients enrolled in 3 consecutive Japanese Children's Cancer and Leukemia Study Group ALL studies (ALL941 [1994 to 2000], n=464; ALL2000 [2000 to 2004], n=305; and ALL2004 [2004 to 2010], n=326). ON was diagnosed in 16 patients, of whom 15 were symptomatic. The cumulative incidence of ON was 0.76% in ALL941, 0.35% in ALL2000, and 3.6% in ALL2004. The incidence of ON in ALL941/2000, in which only prednisolone was administered as a steroid, was significantly lower than that in ALL2004, in which dexamethasone was used as a partial substitute for prednisolone (P<0.01). In ALL2004, sex and age were significantly correlated with the incidence of ON (1.3% in boys vs. 6.7% in girls, P=0.0132; 0.42% for age <10 y vs. 15.6% for age ≥10 y, P<0.0001), suggesting that girls aged 10 years and above are at a greater risk of ON onset. These results indicate that the risk of ON should be considered when administering dexamethasone as part of ALL protocol treatment in girls aged 10 years and above.

    Full Text Available Adult mammals undergo minimal regeneration following cardiac injury, which severely compromises cardiac function and contributes to the ongoing burden of heart failure. In contrast, the mammalian heart retains a transient capacity for cardiac regeneration during fetal and early neonatal life. Recent studies have established the importance of several evolutionarily conserved mechanisms for heart regeneration in lower vertebrates and neonatal mammals including induction of cardiomyocyte proliferation, epicardial cell activation, angiogenesis, extracellular matrix deposition and immune cell infiltration. In this review, we provide an up-to-date account of the molecular and cellular basis for cardiac regeneration in lower vertebrates and neonatal mammals. The historical context for these recent findings and their ramifications for the future development of cardiac regenerative therapies are also discussed.

    Full Text Available Single nucleotide polymorphisms (SNPs in gene encoding pro- and anti-inflammatory factors have been associated with the occurrence of aGvHD. We retrospectively tested a wide panel of 38 polymorphisms in 19 immunoregulatory genes, aiming to first establish, in a pediatric HSCT setting, which SNPs were significantly associated with the development of aGvHD. A significant association was found between aGvHD grades II–IV and SNPs of donor IL10-1082GG, and Fas-670CC + CT and recipient IL18-607 TT + TG genotype. aGvHD grades III-IV resulted associated with donor IL10-1082GG, Fas-670CC + CT, and TLR4-3612TT as well as the use of peripheral CD34+ cells as stem cell source. The multivariate analysis confirmed the association between donor IL10-1082GG and Fas-670CC + CT and aGvHD grades II–IV and between donor IL10-1082GG and TLR4-3612TT and aGvHD grades III-IV. In conclusion we found an association between IL10, FAS, and TLR4 in the donor and IL18 in the recipient and an increased risk of developing aGvHD in transplanted children. Knowledge of the SNPs of cytokine genes associated with aGvHD represents a useful tool for an integrated pretransplantation risk assessment and could guide the physicians to an optimal and more accurate HSCT planning.

  20. Coronary artery visibility in free-breathing young children with congenital heart disease on cardiac 64-slice CT: dual-source ECG-triggered sequential scan vs. single-source non-ECG-synchronized spiral scan

    International Nuclear Information System (INIS)

    The potential impact of dual-source ECG-triggered sequential CT scan on coronary artery visibility has not been evaluated in free-breathing young children. To compare coronary artery visibility in free-breathing young children with congenital heart disease on cardiac 64-slice CT between dual-source ECG-triggered sequential (DSET) scan and single-source non-ECG-synchronized spiral (SSNE) scan. In 93 young children, 108 cardiac 64-slice CT examinations were performed during free-breathing. Visibility of coronary arteries and side branches was compared between SSNE and DSET scans. Heart rates and trigger delays for DSET scan were recorded. Effective dose of each scan technique was calculated. Visual grades were significantly higher (P < 0.001 or =0.011) on DSET scan than on SSNE scan except for the distal left anterior descending artery. Coronary arteries were traceable in 79.3% on DSET scan and 54.3% on SSNE scan in the overlapped scan range (P < 0.0001), and 97.1% and 71.9% for the origins and proximal segments (P < 0.0001). Visibility of side branches was improved on DSET scan by a factor of 2.0. Heart rates and trigger delays for DSET scan were 131 ± 24 beats per min and 199 ± 44 ms, respectively. Effective doses of DSET and SSNE scans were 0.36 ± 0.12 mSv and 0.99 ± 0.23 mSv, respectively. DSET scan improves visibility of coronary arteries on cardiac 64-slice CT in free-breathing young children with congenital heart disease, compared with SSNE scan. (orig.)

    Amyloidoses are a heterogeneous group of multisystem disorders, which are characterized by an extracellular deposition of amyloid fibrils. Typically affected are the heart, liver, kidneys, and nervous system. More than half of the patients die due to cardiac involvement. Clinical signs of cardiac amyloidosis are edema of the lower limbs, hepatomegaly, ascites and elevated jugular vein pressure, frequently in combination with dyspnea. There can also be chest pain, probably due to microvessel disease. Dysfunction of the autonomous nervous system or arrhythmias may cause low blood pressure, dizziness, or recurrent syncope. The AL amyloidosis caused by the deposition of immunoglobulin light chains is the most common form. It can be performed by monoclonal gammopathy. The desirable treatment therapy consists of high-dose melphalan therapy twice followed by autologous stem cell transplantation. Due to the high peritransplantation mortality, selection of appropriate patients is mandatory. The ATTR amyloidosis is an autosomal dominant disorder caused by the amyloidogenic form of transthyretin, a plasmaprotein that is synthesized in the liver. Therefore, liver transplantation is the only curative therapy. The symptomatic treatment of cardiac amyloidosis is based on the current guidelines for chronic heart failure according to the patient's New York Heart Association (NYHA) state. Further types of amyloidosis with possible cardiac involvement comprise the senile systemic amyloidosis caused by the wild-type transthyretin, secondary amyloidosis after chronic systemic inflammation, and the beta(2)-microglobulin amyloidosis after long-term dialysis treatment.

    Objective To discuss the early diagnosis and treatment of cardiac penetrating injuries and pseudoaneurysm. Methods 18 cases of cardiac penetrating injuries, in which 2 cases were complicated with pseudoaneurysm, were diagnosed by emergency operation and color Doppler echocardiography between May 1973 and Dec. 2001 in our hospital. The basis for emergency operation is the injured path locating in cardiac dangerous zone, severe shock or pericardial tamponade. ResultsAmong 18 cases of this study, 17 cases underwent emergency operation. During the operation, 11 cases were found injured in right ventricle, 2 cases were found injured in right atrium, 1 case was found injured in pulmonary artery,4 cases were found injured in left ventricle, 2 cases were found complicated with pseudoaneurysm. 17cases underwent cardiac repair including 1 case of rupture of aneurysm. 1 case underwent elective aneurysm resection. In whole group, 15 cases survived(83.33% ), 3 cases died( 16.67%). The cause of death is mainly hemorrhagic shock. Conclusion Highly suspicious cardiac penetrating injuries or hemopericaridium should undergo direct operative exploration. Pseudoaneurysm should be resected early,which can prevent severe complications.

    The heart must continuously pump blood to supply the body with oxygen and nutrients. To maintain the high energy consumption required by this role, the heart is equipped with multiple complex biological systems that allow adaptation to changes of systemic demand. The processes of growth (hypertrophy), angiogenesis, and metabolic plasticity are critically involved in maintenance of cardiac homeostasis. Cardiac hypertrophy is classified as physiological when it is associated with normal cardiac function or as pathological when associated with cardiac dysfunction. Physiological hypertrophy of the heart occurs in response to normal growth of children or during pregnancy, as well as in athletes. In contrast, pathological hypertrophy is induced by factors such as prolonged and abnormal hemodynamic stress, due to hypertension, myocardial infarction etc. Pathological hypertrophy is associated with fibrosis, capillary rarefaction, increased production of pro-inflammatory cytokines, and cellular dysfunction (impairment of signaling, suppression of autophagy, and abnormal cardiomyocyte/non-cardiomyocyte interactions), as well as undesirable epigenetic changes, with these complex responses leading to maladaptive cardiac remodeling and heart failure. This review describes the key molecules and cellular responses involved in physiological/pathological cardiac hypertrophy. PMID:27262674

    Children undergoing cardiac surgery requiring cardiopulmonary bypass (CPB) frequently develop acute kidney injury due to renal ischemia. Theophylline, which improves renal perfusion via adenosine receptor inhibition, is a potential targeted therapy. However, children undergoing cardiac surgery and CPB commonly have alterations in drug pharmacokinetics. To help understand optimal aminophylline (salt formulation of theophylline) dosing strategies in this population, a population-based pharmacokinetic model was developed using nonlinear mixed-effects modeling (NONMEM) from 71 children (median age 5 months; 90% range 1 week to 10 years) who underwent cardiac surgery requiring CPB and received aminophylline as part of a previous randomized controlled trial. A 1-compartment model with linear elimination adequately described the pharmacokinetics of theophylline. Weight scaled via allometry was a significant predictor of clearance and volume. In addition, allometric scaled clearance increased with age implemented as a power maturation function. Compared to prior reports in noncardiac children, theophylline clearance was markedly reduced across age. In the final population pharmacokinetic model, optimized empiric dosing regimens were developed via Monte Carlo simulations. Doses 50% to 75% lower than those recommended in noncardiac children were needed to achieve target serum concentrations of 5 to 10 mg/L. PMID:26712558

    Objective The object of this study was to review the role of cardiac troponin as a prognostic factor in acute coronary syndrome patients of varying circumstances.Data sources The data used in this review were obtained mainly from the studies of cardiac troponin reported in pubmed from 1981 to 2006.Study selection Relevant articles on studies of cardiac troponin were selected.Results Elevated cardiac troponin in patients with ST elevation and non ST elevation myocardial infarction was associated with adverse outcomes, including a higher incidence of congestive heart failure, shock, and death. Patients with elevated cardiac troponin value seemed to benefit more from invasive strategies including a percutaneous coronary intervention and bypass surgery, but elevated cardiac troponin was also correlated with adverse outcomes, including a higher degree of failure, shock, and mortality in patients undergoing percutaneous coronary intervention; a higher degree of perioperative myocardial infarction, low cardiac output syndrome, cardiopulmonary resuscitation, and new-onset ventricular arrhythmia in patients undergoing bypass surgery were also observed. Elevated troponin after a percutaneous coronary intervention seemed to be associated with short-term adverse outcomes rather than long-term adverse outcomes, unless the elevation of the troponin post percutaneous coronary intervention was quite high (about 5 times above normal). On the contrary, elevated cardiac troponin after bypass surgery was more confusing to analyze since it happened in almost all patients. Furthermore, differences in cutoff values and time measurements in some studies add more confusion; thus, further research is warranted.Conclusions The prognostic value of cardiac troponin is demonstrated in almost all acute coronary syndrome patients. In addition to its high sensitivity and specificity, the prognostic value of cardiac troponin is another reason to make it the "golden cardiac marker' of this time.

    Cardiac sarcoma is a very rare neoplasm and is difficult to diagnose. The case of a 51-year-old man with a left atrial tumour, locally recurrent three months after its surgical removal, is presented. Computed tomography showed metastatic spread to the lung parenchyma. On revised histology, the mass extirpated was a sarcoma. Because of the metastatic spread, further therapy was symptomatic only; the patient died 15 months after the first manifestation of his problems. Immunohistochemical stain...

    This December Issue of Cardiology in the Young represents the 13th annual publication in Cardiology in the Young generated from the two meetings that composed "HeartWeek in Florida". "HeartWeek in Florida", the joint collaborative project sponsored by the Cardiac Centre at the Children's Hospital of Philadelphia, Philadelphia, Pennsylvania, together with Johns Hopkins All Children's Heart Institute of Saint Petersburg, Florida, averages over 1000 attendees every year and is now recognised as one of the major planks of continuing medical and nursing education for those working in the fields of diagnosis and treatment of cardiac disease in the foetus, neonate, infant, child, and adult. "HeartWeek in Florida" combines the International Symposium on Congenital Heart Disease, organised by All Children's Hospital and Johns Hopkins Medicine, and entering its 16th year, with the Annual Postgraduate Course in Paediatric Cardiovascular Disease, organised by The Children's Hospital of Philadelphia entering its 19th year. This December 2015 Issue of Cardiology in the Young features highlights of the two meetings that compose HeartWeek. Johns Hopkins All Children's Heart Institute's 15th Annual International Symposium on Congenital Heart Disease was held at the Renaissance Vinoy Resort & Golf Club, Saint Petersburg, Florida, from Friday, 6 February, 2015, to Monday, 9 February, 2015. This Symposium was co-sponsored by The American Association for Thoracic Surgery and its special focus was "Congenital Abnormalities of the Coronary Arteries". The Children's Hospital of Philadelphia's annual meeting - Cardiology 2015, the 18th Annual Update on Paediatric and Congenital Cardiovascular Disease: "Challenges and Dilemmas" - was held at the Hyatt Regency Scottsdale Resort and Spa at Gainey Ranch, Scottsdale, Arizona, from Wednesday, 11 February, 2015, to Sunday, 15 February, 2015. We would like to acknowledge the tremendous contributions made to paediatric and congenital cardiac care

    A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was 'do children with heart failure post-cardiac surgery undergoing treatment with levosimendan have an acceptable haemodynamic improvement?' The use of levosimendan as a vasoactive drug is an accepted intervention for patients with altered haemodynamics post-cardiac surgeries. However, the role of levosimendan and its efficacy have been debated. Eleven relevant papers were identified, which represented the best evidence to answer the question. The author, journal, date, country of publication and relevant outcomes are tabulated. The 11 studies comprised 3 randomized trials, 2 of which compared levosimendan and milrinone. A single-centre randomized study that included 40 infants showed that cardiac output (CO) and cardiac index (CI) increased overtime in the levosimendan group compared with the milrinone group. The significant interaction for CO (P = 0.005) and CI (P = 0.007) indicated different time courses in the two groups. A similar, European randomized study undertaken on neonates (n = 63) showed better lactate levels [P = 0.015 (intensive care admission); P = 0.048 (after 6 h) with low inotropic scores in the levosimendan group. Although the length of mechanical ventilation and mortality were less, this was statistically insignificant. A retrospective cohort analysis (n = 13) in children reported a reduced use of dobutamine and improvement in the ejection fraction from 29.8 to 40.5% (P = 0.015) with the use of levosimendan. In a questionnaire-based study from Finland, 61.1% of respondents felt that it had saved the lives of some children when the other treatments had failed. No study reported any adverse effect attributable to use of levosimendan. In conclusion, the above studies were in favour of levosimendan as a safe and feasible drug providing potential clinical benefit in low cardiac output syndrome (LCOS) and post-cardiac surgeries when

    Extracorporeal life support (ECLS) is an important device in the management of children with severe refractory cardiac and or pulmonary failure. Actually, two forms of ECLS are available for neonates and children: extracorporeal membrane oxygenation (ECMO) and use of a ventricular assist device (VAD). Both these techniques have their own advantages and disadvantages. The intra-aortic balloon pump is another ECLS device that has been successfully used in larger children, adolescents, and adults, but has found limited applicability in smaller children. In this review, we will present the “state of art” of ECMO in neonate and children with heart failure. ECMO is commonly used in a variety of settings to provide support to critically ill patients with cardiac disease. However, a strict selection of patients and timing of intervention should be performed to avoid the increase in mortality and morbidity of these patients. Therefore, every attempt should be done to start ECLS “urgently” rather than “emergently,” before the presence of dysfunction of end organs or circulatory collapse. Even though exciting progress is being made in the development of VADs for long-term mechanical support in children, ECMO remains the mainstay of mechanical circulatory support in children with complex anatomy, particularly those needing rapid resuscitation and those with a functionally univentricular circulation. With the increase in familiarity with ECMO, new indications have been added, such as extracorporeal cardiopulmonary resuscitation (ECPR). The literature supporting ECPR is increasing in children. Reasonable survival rates have been achieved after initiation of support during active compressions of the chest following in-hospital cardiac arrest. Contraindications to ECLS have reduced in the last 5 years and many centers support patients with functionally univentricular circulations. Improved results have been recently achieved in this complex subset of patients. PMID

    Objective Right ventricular (RV) function is an independent prognosis predictor in patients undergoing cardiac surgery. The objective of this study is to evaluate the feasibility of quantifying RV function by Two-dimensional speckle tracking imaging (2D-STI); and to assess the influence of LV function and the cardiac surgery on RV function. Methods 2D-ST1 was performed in 61 patients who undergone cardiac surgery and 25 healthy subjects (Control group). The imaging was analyzed offline with Qlad 6. 0 TMQA to determine the longitudinal RV peak systolic strain (e) and the peak systolic velocity (S) of the 3 segments of RV free wall. The RV functional parameters were compared between patients with preserved LVEF (LVEF>50%) and with decreased LVEF (LVEF<50%), Meanwhile, the postoperative change of RV function was monitored 1 week, 3 months and six months after the surgery, and was compared with the pre-operative data. Results Patients with decreased LVEF had lower RV systolic peak strain and velocity, as compared both with preserved LVEF group (P<0.05) and with control group (P< 0. 05). There were no differences of RV functional parameters between the patients with preserved LVEF and the controls. Both in CPB group (n=33) and in OP group (n=28), RV systolic peak strain and velocity were decreased significantly 1 week after surgery as compared with those preoperative; and then recovered 3 and 6 months after surgery, with no difference when comparing with preoperative data and with those of control group. Conclusions 2D-ST1 could be a promising technique to quantify and monitor RV function noninvasively. The longitudinal systolic peak strain of free wall would be used as RV functional parameters. Patients with abnormal LVEF had damaged RV deformation and motion function. No matter under which pattern of circulation, cardiac surgery could do harm to RV function transiently; the reversible injury would be recovered in about 3 months after the surgery.%目的 右心室功

Positive predictive values were established comparing NPR information with the clinical record of each individual.Results: A total of 2952 patients with a total of 3536 diagnoses were eligible for validation. Review of their clinical records unveiled no patient without cardiac malformation. In 98% (98%–99% of the cases, the NPR diagnosis could be found as the discharge diagnosis in the patient's clinical record, and in 90% (89%–91% of the cases the NPR diagnosis was considered a true reflection of the patient's actual malformation.Conclusions: Our study verifies that the present study population retrieved from the NPR is a valid tool for epidemiological research within the topic of congenital cardiac malformations, given that the research question is not dependent on a fully established sensitivity of the NPR. Precautions should be made regarding cardiac malformations characterized by low prevalence or poor predictive values, and the reported validity should not be

    Objective To describe changes in body composition of children during acute period after hematopoietic stem transplantation and to analyze their related factors. Methods From January to September 2012,40 patients undergoing hematopoietic stem cell transplantation in Shanghai Children's Medical Center were prospectively enrolled into the study. Height, weight and body composition were measured by direct segmental multi-frequency bioelectrical impedance analysis (DSM-BIA) were recorded before transplantation and at the 30th, 60th and 100th day after transplantation. Sex, age, transplantation method, graft source,total body irradiation,use of methylprednisolone, infection, the grade of mucositis and acute graft-versus-host disease (aGVHD) grade were also recorded. Results After hematopoietic stem cell transplantation, no significant change was observed in height Z-scores (F=0. 75,P = 0. 3883); body mass index(BMI) Z-values and fat-free mass for height (FFM-Ht) were significantly decreased but fat mass for height(FM-Ht) was also significantly increased(P<0. 05 or P<0. 01). After controlling children's age, the graft source was a significant factor affecting BMI Z and the total body irradiation was a significant factor affecting FM-Ht and infection was the a risk factor of FFM-Ht. Conclusion Children have high risks of emaciation and obesity during the acute period after hematopoietic stem cell transplantation. Irradiation may increase their fat mass, while infection may decreases fat-free mass. BMI may not be a good indicator to assess nutrition status of children undergoing transplantation.%目的 了解造血干细胞移植患儿急性期的人体组分变化情况并分析其相关因素.方法 前瞻性收集2012年1月至2012年9月在上海儿童医学中心进行造血干细胞移植的40例患儿的临床资料,在患儿进行造血干细胞移植前、移植后的第30、60和100天测量其身高、体质指数及使用直接节段多频生物电阻抗分析

The aim of this study is to examine the significance of abnormal RVEF by cardiac magnetic resonance (CMR, independent of LVEF in predicting outcomes of patients undergoing isolated CABG and valve surgery.From 2007 to 2009, 109 consecutive patients (mean age, 66 years; 38% female were referred for pre-operative CMR. Abnormal RVEF and LVEF were considered 30 days outcomes included, cardiac re-hospitalization, worsening congestive heart failure and mortality. Mean clinical follow up was 14 months.Forty-eight patients had reduced RVEF (mean 25% and 61 patients had normal RVEF (mean 50% (p<0.001. Fifty-four patients had reduced LVEF (mean 30% and 55 patients had normal LVEF (mean 59% (p<0.001. Patients with reduced RVEF had a higher incidence of long-term cardiac re-hospitalization vs. patients with normal RVEF (31% vs.13%, p<0.05. Abnormal RVEF was a predictor for long-term cardiac re-hospitalization (HR 3.01 [CI 1.5-7.9], p<0.03. Reduced LVEF did not influence long-term cardiac re-hospitalization.Abnormal RVEF is a stronger predictor for long-term cardiac re-hospitalization than abnormal LVEF in patients undergoing isolated CABG and valve procedures.

    Full Text Available Background: Post-operative fever is a common complication of cardiac operations, which is known to be correlated with a greater degree of cognitive dysfunction 6 weeks after cardiac surgery. The aim of the present study was to examine efficacy and safety of single dose intravenous Paracetamol in treatment of post-operative fever in children undergoing cardiac surgery. Materials and Methods: In this randomised, double-blind, placebo-controlled clinical trial, 80 children, aged 1-12 years, presenting for open heart surgery were entered in the trial and randomly allocated into two groups: Placebo and Paracetamol. After induction of anaesthesia, 15 mg/kg intravenous Paracetamol solution was infused during 1 h in the Paracetamol group. Patients in placebo group received 15 mg/kg normal saline infusion during the same time. Since the end of operation until next 24 h in intensive care unit, axillary temperature of the two group patients was recorded in 4-h intervals. Any fever that occurred during this period had been treated with Paracetamol suppository (125 mg and the amount of antipyretic drug consumption for each patient had been recorded. In order to examine the safety of Paracetamol, patients were evaluated for drug complication at the same time. Results: Mean axillary temperature during first 24 h after operation was significantly lower in Paracetamol group compared with placebo group (P = 0.001. Overall fever incidence during 24 h after operation was higher in placebo group compared with Paracetamol group (P = 0.012. Of Paracetamol group patients, 42.5% compared with 15% of placebo group participants had no consumption of antipyretic agent (Paracetamol suppository during 24 h after operation (P = 0.001. Conclusion: This study suggests that single dose administration of intravenous Paracetamol before paediatric cardiac surgeries using cardiopulmonary bypass; reduce mean body temperature in the first 24 h after operation.

    Paediatric cardiac catheterizations may result in the administration of substantial amounts of iodinated contrast media and ionizing radiation. The aim of this work was to investigate the effect of iodinated contrast media in combination with in vitro and in vivo X-ray radiation on lymphocyte DNA. Six concentrations of iodine (15, 17.5, 30, 35, 45, and 52.5 mg of iodine per mL blood) represented volumes of iodinated contrast media used in the clinical setting. Blood obtained from healthy volunteers was mixed with iodinated contrast media and exposed to radiation doses commonly used in paediatric cardiac catheterizations (0 mGy, 70 mGy, 140 mGy, 250 mGy and 450 mGy). Control samples contained no iodine. For in vivo experimentation, pre and post blood samples were collected from children undergoing cardiac catheterization, receiving iodine concentrations of up to 51 mg of iodine per mL blood and radiation doses of up to 400 mGy. Fluorescence microscopy was performed to assess γH2AX-foci induction, which corresponded to the number of DNA double-strand breaks. The presence of iodine in vitro resulted in significant increases of DNA double-strand breaks beyond that induced by radiation for ≥ 17.5 mg/mL iodine to blood. The in vivo effects of contrast media on children undergoing cardiac catheterization resulted in a 19% increase in DNA double-strand breaks in children receiving an average concentration of 19 mg/mL iodine to blood. A larger investigation is required to provide further information of the potential benefit of lowering the amount of iodinated contrast media received during X-ray radiation investigations.

    Objective Non-pharmacological approaches to pain management have been used by therapists for decades to reduce the anxiety and pain experienced by children during burn care procedures. With a greater understanding of pain and the principles behind what causes a child to be distracted, com-bined with access to state of the art technology, we have developed an easy to use, hand held multimodal distraction device (MMD). MMD is an interactive device that prepares the child for a procedure and uses developmentally appropriate distraction stories and games during the procedures to alleviate anxiety and pain. This paper summarizes the results of three randomized control trials. The trials aimed to understand the effec-tiveness of MMD as a distraction and preparation tool in reducing anxiety and pain in children undergoing burns and non-burns medical procedures compared to pure pharmacological approaches Standard Distraction (SD) and off the shelf video games (VG). Methods Three separate prospective randomized control tri-als involving 182 children having 354 dressing changes were conducted in the burns and orthopedic depart-ments at Royal Children's Hospital, Brisbane, Australia, to address the above aims. Pain and anxiety scores were completed for the child, caregivcr and nursing staff according to the Modified Faces, Legs, Activity, Cry and Consolability Scale, Faces Pain Scale-Revised, Visual Analogue Scale and Wong-Baker Faces Pain Rating Scale. Procedural length was recorded. Results MMD as a preparation and distraction tool were shown to have a significant impact on child, parent and nursing staff reported anxiety and pain daring proce-dures compared to standard care and video games (P<0.01). The MMD had a positive effect on clinical time and was shown to sustain its impact on pain and time with further dressing changes. Conclusions MMD is more effective in reducing the pain and anxiety experienced by children in acute medical procedures as compared with SD and VG

    Objective To investigate the myocardial protection effects of radical scavenger edaravone(MCI-186) combined with fructose-1, 6-diphosphate(FDP) in patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB). Methods Forty patients with rheumatic heart disease undergoing mitral,aortic,mitral or aortic valve replacement were randomly divided into four groups: control group (group A),group MCI-186 g(group B),group FDPCgroup C),MCI-186 and FDP combination group (group D, 72=10 each). The same volume of saline solution was infused intravenously in group A. Group B received edaravone injection 0. 5 mg/kg in cardioplegia solution. 200 mg/kg FDP was intravenously infused before aorta-clamping in group C. Edaravone 0. 5 mg/kg was mixed with CPB priming fluid and FDP 200 mg/kg was given intravenously 15 min before aortic cross clamp in group D. Plasma activity of superoxide dismulase (SOD) and levels of malondialdehyde (MDA), creatinekinase-MB and cardiac troponin I were measured before skin incision (T1), before aortic-clamping(T2), at 2 h and 6 h after CPB and 24 h postoperative (T3-T5). Meanwhile, the clinical effectiveness of each group was observed. Results Compared with T1, SOD activity decreased significantly at T2-T4in group A, while the levels of serum MDA, CK-MB at T3-T5 and cTnl at T2-T5 increased significantly in all groups(P<0. 05). Compared with group A, SOD activity at T2-T4 increased significantly, while levels of serum MDA and CK-MB at T3-T5 decreased in other groups, the levels of cTnl in group B,C,D at T3 and in group B,D at T4 were obviously decreased. (P<0. 05 or P <0. 01). The concentration of cTnl in group B and C was obviously higher than that in group D at T3 ,T4 (P<0. 05). The consumption of dopa mine and drainage quantity within 24 h after surgery were much more in group A than those in group D(P<0. 05).

Recommendations are made regarding the style of analysis used to assess heartbeat perception in such tracking tasks. PMID:348240

  1. Ultrafast MR imaging with EPI of organs undergoing nonperiodic motion

    International Nuclear Information System (INIS)

    Conventional MR imaging employing repetitive data acquisition is susceptible to motion artifacts. Gating overcomes periodic motion effects. Nonperiodic motion, as encountered in the gastronintestinal tract, cardiac arrhythmias, unsedated children, and fetal imaging, thwarts conventional MR imaging. The EPI derivatives BEST and MBEST create a complex 128 x 128-pixel image in 64 msec and 128 msec, respectively, freezing motion almost completely. Sequentially recorded gastrointestinal-tract images allow quantitative evaluation of gastric and gut motility. Cardiac morphology, movement, and blood flow patterns in valvular heart disease have been depicted during atrial fibrillation. Selected clinical results with accompanying technical details illustrate the scope of EPI as a distinctive imaging modality

    2009-01-01

    Full Text Available Pediatric cardiac surgery is undergoing a metamorphosis, with more and more critical patients being operated in our country today. Although the principles of physiology have not changed, it is imperative that care providers continue to stay abreast with developments and newer drugs that may help modify the outcome. The team dynamics have also become more complex, which necessitates the need for all care providers (surgeons, cardiologists, anesthesiologists, and intensivists to better understand the interactions and benefits of newer drugs. Vasopressin has been used in our adult patients for more than a decade and recently has found its rightful place in the pediatric armoury. The objective of this article is to review the physiology of vasopressin and the rationale of its use in critically ill children with shock, in context of the available published data.

    2011-01-01

    Full Text Available Indications for extra corporeal membrane oxygenation (ECMO after pediatric cardiac surgery have been increasing despite the absence of encouraging survival statistics. Modification of ECMO circuit led to the development of integrated ECMO cardiopulmonary bypass (CPB circuit at the author′s institute, for children undergoing repair of transposition of great arteries among other congenital heart diseases (CHD. In this report, they analyzed the outcome of children with CHD, undergoing surgical repair and administered ECMO support in the last 10 years. The outcome was analyzed with reference to the timing of intervention, use of integrated ECMO-CPB circuit, indication for ECMO support, duration of ECMO run and the underlying CHD. The results reveal a significantly improved survival rate with the use of integrated ECMO-CPB circuit and early time of intervention rather than using ECMO as a last resort in the management. The patients with reactive pulmonary artery hypertension respond favorably to ECMO support. In all scenarios, early intervention is the key to survival.

    Full Text Available The number of patients with a previously diagnosed malignancy who need cardiac surgery is increasing. Patients with hematological malignancies represent only 0.38% of all patients undergoing cardiac surgery. The literature in this subset of patients is limited to only a few retrospective case series, with limited number of patients undergoing emergency cardiac surgery. We describe three cases with hematological malignancies namely chronic myelogenous leukemia, acute promyelocytic leukemia and chronic lymphocytic leukemia presenting for coronary artery bypass grafting (CABG. Two patients were taken up for emergency CABG in view of ongoing ischemia, one of them was on preoperative intra-aortic balloon pump support. No mortality was observed. Two patients needed transfusion of blood products which was guided by thromboelastography. One patient developed superficial sternal wound infection requiring antibiotic therapy.

  2. Stimulating endogenous cardiac regeneration

    Full Text Available The healthy adult heart has a low turnover of cardiac myocytes. The renewal capacity, however, is augmented after cardiac injury. Participants in cardiac regeneration include cardiac myocytes themselves, cardiac progenitor cells, and peripheral stem cells, particularly from the bone marrow compartment. Cardiac progenitor cells and bone marrow stem cells are augmented after cardiac injury, migrate to the myocardium, and support regeneration. Depletion studies of these populations have demonstrated their necessary role in cardiac repair. However, the potential of these cells to completely regenerate the heart is limited. Efforts are now being focused on ways to augment these natural pathways to improve cardiac healing, primarily after ischemic injury but in other cardiac pathologies as well. Cell and gene therapy or pharmacological interventions are proposed mechanisms. Cell therapy has demonstrated modest results and has passed into clinical trials. However, the beneficial effects of cell therapy have primarily been their ability to produce paracrine effects on the cardiac tissue and recruit endogenous stem cell populations as opposed to direct cardiac regeneration. Gene therapy efforts have focused on prolonging or reactivating natural signaling pathways. Positive results have been demonstrated to activate the endogenous stem cell populations and are currently being tested in clinical trials. A potential new avenue may be to refine pharmacological treatments that are currently in place in the clinic. Evidence is mounting that drugs such as statins or beta blockers may alter endogenous stem cell activity. Understanding the effects of these drugs on stem cell repair while keeping in mind their primary function may strike a balance in myocardial healing. To maximize endogenous cardiac regeneration,a combination of these approaches couldameliorate the overall repair process to incorporate the participation ofmultiple cell players.

    Full Text Available Introduction. Despite remarkable advances in medicine and sports, sudden cardiac death remains a significant problem. Incidence of sudden cardiac death. The incidence of sudden cardiac death varies in different studies and there are no systematic data about it. It varies in different types of sports, with age and sex. Sudden cardiac death and physical activity. Many changes in cardiac morphology and function represent an adaptive response to physical activity. As a result, the heart undergoes profound morphologic, functional and electro-physiological alterations. But as there are different kinds of physical activities, the degree of these morphological changes is highly variable. It is needless to say how important it is to know which changes in the heart due to physical activity are normal, and when they are pathological. Considering the results of many studies, the main cause of sudden cardiac death is hypertrophic cardiomiopathy. Conclusion. It is very important to distinguish physiological changes of the heart due to physical activity, and pathological changes due to some cardiac diseases. That is why, clear recommendations on intensity, type, duration and frequency of physical training in every sports discipline are necessary. That is the only way to decrease the incidence of sudden cardiac death in athletes. .

    Background Few studies have examined the properties of human immunodeficiency virus type 1 (HIV-1) epitope-specific cytotoxic T lymphocyte (CTL) responses in children. To address this issue, we characterized epitope-specific CTL responses and analyzed the determinants that may affect CTL responses before and after highly active antiretroviral therapy (HAART) in children with HIV-1 infection.Methods A total of 22 HIV-1-infected children and 23 uninfected healthy children as control were enrolled in the study. Circulating CD4 T cells and HIV-1 RNA load in plasma were routinely measured. Peripheral HIV-1-specific CTL frequency and HIV-1 epitope-specific, interferon-γ (IFN-γ)-producing T lymphocytes were measured using tetramer staining and enzyme-linked immunospot (ELISPOT) assay, respectively.Circulating dendritic cell (DC) subsets were monitored with FACS analysis.Results More than 80% of the children with HIV-1 infection exhibited a positive HIV-1-epitope-specific CTL response at baseline, but HIV-specific CTLs and IFN-γ-producing lymphocytes decreased in patients who responded to HAART in comparison with non-responders and HAART-naive children. The duration of virus suppression resulted from HAART was inversely correlated with CTL frequency. While in HAART-naive children, HIV-1-specific CTL frequency was positively correlated with myeloid DC (mDC) frequency,although the cause and effect relationship between the DCs and CTLs remains unknown.Conclusions HIV-1-epitope-specific CTL responses are dependent on antigenic stimulation. The impaired DC subsets in blood might result in a defect in DC-mediated T cell responses. These findings may provide insight into understanding the factors and related mechanisms that influence the outcome of HIV-1 carriers to HAART or future antiviral therapies.

    Objective To evaluate prediction validation of Sino System for Coronary Operative Risk Evaluation (SinoSCORE) on in-hospital mortality in adult heart surgery patients in West China Hospital. Methods We included clinical records of 2 088 consecutive adult patients undergoing heart surgery in West China Hospital from January 2010 to May 2012, who were also included in Chinese Adult Cardiac Surgical Registry.We compared the difference of preopera-tive risk factors for the patients between Chinese Adult Cardiac Surgical Registry and West China Hospital. SinoSCORE was used to predict in-hospital mortality of each patient and to evaluate the discrimination and calibration of SinoSCORE for the patients. Results Among the 2 088 patients in West China Hospital, there were 168 patients (8.05%) undergoing coronary artery bypass grafting (CABG), 1 884 patients (90.23%) undergoing heart valve surgery, and 36 patients (1.72%) undergoing other surgical procedures. There was statistical difference in the risk factors including hyperlipemia, stroke, cardiovascular surgery history, and kidney disease between the two units.The observed in-hospital mortality was 2.25% (47/2 088). The predicted in-hospital mortality calculated by SinoSCORE was 2.35% (49/2 088) with 95% confidence interval 2.18 to 2.47. SinoSCORE was able to predict in-hospital mortality of the patients with good discrimination (Hosmer-Lemeshow test: x2 =3.164, P=0.582) and calibration (area under the receiver operating characteristic curve of 0.751 with 95% confidence interval 0.719 to 0.924).

    Left atrium and/or left ventricle dilatation on echocardiography is considered to be an indication for closure of ventricular septal defects (VSD). No study has addressed the accuracy of using dilated left heart chambers when defining significant left-to-right shunting quantified by cardiac catheterization in isolated small or moderate VSDs. In this study, the relation between dilated left heart chambers, measured by echocardiography, and left-to-right ventricle shunting, quantified by cardiac catheterization, was evaluated in patients with isolated VSD. The medical records of all patients with isolated VSD who had undergone catheterization from 1996 to 2010 were examined retrospectively. Normative data for left heart chambers adjusted for body weight (BW) and body surface area (BSA) were used. The pulmonary-to-systemic flow ratio (Qp:Qs) was calculated by an oximetry technique. A total of 115 patients (mean age 7.3 ± 5 years) fulfilled the inclusion criteria. There was a statistically significant difference in terms of Qp:Qs between the patient groups with normal and dilated left heart chambers, when adjusted for BW and BSA (p = 0.001 and p = 0.002, respectively). But the relationships between Qp:Qs and left heart chamber sizes on echocardiography were not strong enough to be useful for making surgical decisions, as left heart chamber dilatation was not significantly associated with Qp:Qs ≥ 2 (p = 0.349 when adjusted for BW, p = 0.107 when adjusted for BSA). Left heart chamber dilatation was significantly associated with Qp:Qs ≥ 1.5 only when it was adjusted for BSA (for BW p = 0.022, for BSA p = 0.006). As a result, left heart chamber dilatation measured by echocardiography does not show significant left-to-right ventricle shunting, as quantified by catheterization. We still advocate that catheter angiography should be undertaken when left heart chambers are dilated in echocardiography in order to make decisions about closing small- to moderate-sized VSD.

    Previous studies showed that decreased cerebral saturation during cardiac surgery is related to adverse postoperative outcome. Therefore, we investigated the influence of intraoperative events on cerebral tissue saturation in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). A total of 52 adult patients who underwent cardiac surgery using pulsatile CPB were included in this prospective explorative study. Cerebral tissue oxygen saturation (SctO2) was measured in both the left and right cerebral hemisphere. Intraoperative events, involving interventions performed by anesthesiologist, surgeon, and clinical perfusionist, were documented. Simultaneously, in-line hemodynamic parameters (partial oxygen pressure, partial carbon dioxide pressure, hematocrit, arterial blood pressure, and CPB flow rates) were recorded. Cerebral tissue saturation was affected by anesthetic induction (p partial oxygen pressures changed. Cerebral tissue oximetry effectively identifies changes related to surgical events or vulnerable periods during cardiac surgery. Future studies are needed to identify methods of mitigating periods of reduced cerebral saturation. PMID:26390677

    The population of children with end-stage heart failure requiring mechanical circulatory support is growing. These children present for diagnostic imaging studies, various interventions and noncardiac surgical procedures that require anesthetic care. This article is a review of the population demographics of children on mechanical cardiac support, the alternative devices available, and the important concepts for safe perioperative management of these patients. The discussion will be limited to devices for short- and long-term cardiac support, excluding extracorporeal membrane oxygenation (ECMO) for respiratory support. PMID:21332879

    There are two components of cardiac CT discussed in this article: coronary artery calcium scoring (CACS) and coronary computed tomography angiography (CCTA).The distinctive advantages of each CT examination are outlined. In order to ensure a successful cardiac CT program, it is imperative that imaging facilities market their cardiac CT practices effectively in order to gain a competitive advantage in this valuable market share. If patients receive quality care by competent individuals, they are more likely to recommend the facility's cardiac CT program. Satisfied patients will also be more willing to come back for any further testing.

    1987-01-01

    To evaluate the effect of furosemide on cardiovascular hemodynamics in patients with end-stage renal failure, we studied ten patients undergoing hemodialysis three times a week. Arterial pressure, heart rate, and cardiac output (indocyanine green dye) were measured in triplicate; total peripheral resistance and central blood volume were calculated by standard formulas. Hemodynamics were determined at baseline and 5, 10, 15, and 30 minutes after intravenous (IV) bolus injection of furosemide 60 mg. Furosemide produced a decrease in central blood volume of -13% +/- 2.2% from pretreatment values (P less than .01) that was most pronounced five minutes after injection, together with a fall in cardiac output (from 6.76 +/- 0.59 to 6.17 +/- 0.52 L/min, P less than .10). Stroke volume decreased with a maximum fall occurring after 15 minutes (from 84 +/- 7 to 79 +/- 7 mL/min, P less than .05), and total peripheral resistance increased (from 15.8 +/- 2.1 to 17.8 +/- 2.3 units, P less than .05) after furosemide. Arterial pressure and heart rate did not change. The decrease in central blood volume reflects a shift of the total blood volume from the cardiopulmonary circulation to the periphery, suggesting dilation of the peripheral venous bed. Thus, even in patients undergoing hemodialysis, furosemide acutely decreases left ventricular preload by venous dilation and should therefore prove to be beneficial in acute volume overload.

    Minimally invasive surgery is an attractive choice for patients undergoing major cardiac surgery. We review the history of minimally invasive valve surgery in this article. Due to many innovations in surgical tools, cardiopulmonary bypass systems, visualization systems, and robotic systems as well as surgical techniques, minimally invasive cardiac surgery has become standard care for valve lesion repair. In particular, aortic cross-clamp techniques and methods for cardioplegia using the Chitwood clamp and root cannula or endoballoon catheter in combination with femoro-femoral bypass systems have made such procedures safer and more practical. On the other hand, robotically assisted surgery has not become standard due to the cost and slow learning curve. However, along with the development of robotics, this less-invasive technique may provide another choice for patients in the near future. PMID:27295770

  1. Cardiac Aging Detection Using Complexity Measures

    CERN Document Server

    Balasubramanian, Karthi

    2016-01-01

    As we age, our hearts undergo changes which result in reduction in complexity of physiological interactions between different control mechanisms. This results in a potential risk of cardiovascular diseases which are the number one cause of death globally. Since cardiac signals are nonstationary and nonlinear in nature, complexity measures are better suited to handle such data. In this study, non-invasive methods for detection of cardiac aging using complexity measures are explored. Lempel-Ziv (LZ) complexity, Approximate Entropy (ApEn) and Effort-to-Compress (ETC) measures are used to differentiate between healthy young and old subjects using heartbeat interval data. We show that both LZ and ETC complexity measures are able to differentiate between young and old subjects with only 10 data samples while ApEn requires at least 15 data samples.

    The 2014 American College of Cardiology and American Heart Association guidelines on perioperative evaluation recommend differentiating patients at low risk (discriminate adverse cardiac events in a cohort of adult patients undergoing elective orthopedic surgery. We retrospectively reviewed 1,098 consecutive, elective orthopedic surgeries performed at Hershey Medical Center from January 1, 2013, to December 31, 2014. Adverse cardiac events were defined as myocardial infarction or cardiac arrest within 30 days of surgery. The mean estimated risk for adverse cardiac events using the NSQIP MICA risk calculator was 0.54%, which was not significantly different (p = 1) compared with the observed incidence of 0.64% (7 of 1,098 procedures). The c-statistic for discriminating adverse cardiac events was 0.85 (95% CI 0.67 to 1) for the NSQIP MICA risk calculator and 0.9 (95% CI 0.75 to 1) for the Revised Cardiac Risk Index. In conclusion, the NSQIP MICA risk calculator is a good discriminator of adverse cardiac events in patients undergoing elective hip and knee surgery, performing comparably to the Revised Cardiac Risk Index.

    Before non-cardiac surgery, evaluation of cardiac function is no frequent part of surgical treatment. European societies of anesthesiology and cardiology published consensus-guidelines in 2014 to present a reasonable approach for preoperative evaluation. This paper intends to differentiate the composite of perioperative risk and to display the guidelines methodical approach to handle it. Features to identify patients at risk from an ageing population with comorbidities, are the classification of surgical risk, functional capacity and risk indices. Application of diagnostic means, should be used adjusted to this risk estimation. Cardiac biomarkers are useful to discover risk of complications or mortality, that cannot be assessed by clinical signs. After preoperative optimization and perioperative cardiac protection, the observation of the postoperative period remains, to prohibit complications or even death. In consideration of limited resources of intensive care department, postoperative ward rounds beyond intensive care units are considered to be an appropriate instrument to avoid or recognize complications early to reduce postoperative mortality.

    Sri Lanka is an island nation in Indian Ocean that provides free healthcare to all citizens through government healthcare system. It has commendable health indices in the region. Pediatric cardiac services have rapidly progressed over past few years helping to further bring down infant and under-five mortality rates. Lady Ridgeway Hospital for Children (LRH) is the only tertiary care referral center for children with heart disease in the country. Currently it performs approximately 1,000 cardiac catheterizations and 1,000 cardiac surgeries every year. Target is to double the surgical output to treat all children with heart diseases in a timely and appropriate manner. Being a middle-income country, this is not an easy task. Technology used in diagnosis and treatment of congenital heart diseases is rapidly advancing with its price tag. In such a setting, it is challenging to proceed to achieve this target in a resource-limited environment. PMID:26085764

Methods The 1230 cases aged 60-80 years, mean (67. 2±10. 2) years undergoing selected PCI with the drug eluting stent were enrolled. The 615 cases of the ADP guided group according to the ADP-induced platelet aggregation index. After the first loading dose of clopidogrel (300 mg) , once the decrease of ADP-induced platelet aggregation index was more than 50% as compared with the basic level, the dose of 75 mg each day would be maintained for one year. If the decrease of the index was less than 50%. the another 300 mg of clopidogrel would be given again, until up to 900 mg on the 3th day. If the decrease of the index was still not enough, the combination of clopidogrel 75 mg, cilostazol 100 mg and aspirin 100 mg each day would be suggested. The rest 615 patients in the routine dosage group took the routine dose of clopidogrel (the first loading dosage 300 mg was taken, then 75 mg each day for one year ) . The MACEs, including cardiac death, myocardium infarction, revascularization and stent thrombosis, were observed for 12 months. Results After the first 300 mg of clopidogrel, only 45% of patients reached the standards. Until reaching 900 mg, 67.5% of patients in the ADP guided group were eligible. The tailored clopidogrel loading dose in the ADP guided group yielded a better effect on the inhibition of platelet aggregation (the routine dose vs. the tailored loading dose: 45% vs. 67. 5% , P=0. 028). After one year follow up, the MACEs were less in ADP guided group than in routine dosage group (2. 8% vs. 4. 9% , P = 0. 035). All of patients had no major bleeding, and the minor bleeding and other

    The beginnings of the Paediatric Cardiac Surgery in the Czech Republic date back to the period immediately after the end of World War II. Its protagonists were Prof. Emerich Polák from the Surgical Clinic in Prague, Vinohrady, Prof. Jan Bedrna from Surgical Clinic in Hradec Kralove, Prof. Vladislav Rapant from Surgical Clinic in Olomouc and Prof. Václav Kafka from the Second Surgical Clinic in Prague. They started with operations of the patent ductus arteriosus, the Blalock-Taussig shunt in cyanotic heart defects and resection of coarctation of the aorta. Operations of congenital heart defects, on the open heart were elaborated namely by cardiosurgeons in Brno, under the leadership of Professor Jan Navrátil. On the extension of those methods participated Professor Jaroslav Procházka in Hradec Kralove and Prof. Václav Kafka at the newly opened department of Paediatric surgery in Prague. In the next period, attention of paediatric cardiac surgery was directed at operations of critical congenital heart defects in the smallest children. Palliative operations of the critical heart defects in newborns and infants were first introduced at the clinic of paediatric surgery of the Paediatric University Hospital in Prague. Radical operations of infants and newborns with extra-corporal circulation were elaborated in the Children's heart centre in Prague, Motol. Initiative in the further development of paediatric cardiac surgery was taken over by the Children's heart centre in Prague since its founding in 1977. There was concentrated all medical care of children born with a congenital heart defect in the Czech Republic. This concentration of specialized care at one institution allowed to accumulate extremely large experience with the diagnostics and surgical treatment of congenital heart defects in all age groups with the decrease of patients mortality after operations to 1% even for the smallest children and enabled continuously monitor the quality of life of patients

    Cardiac surgery represents a sub-group of patients at significantly increased risk of intraoperative awareness. Relatively few recent publications have targeted the topic of awareness in this group. The aim of this review is to identify areas of awareness research that may equally be extrapolated to cardiac anesthesia in the attempt to increase understanding of the nature and significance of this scenario and how to reduce it.

    The purpose of this review is to give an overview of the rehabilitation measures provided for cardiac patients in Germany and to outline its legal basis and outcomes. In Germany the cardiac rehabilitation system is different from rehabilitation measures in other European countries. Cardiac rehabilitation in Germany since 1885 is based on specific laws and the regulations of insurance providers. Cardiac rehabilitation has predominantly been offered as an inpatient service, but has recently been complemented by outpatient services. A general agreement on the different indications for offering these two services has yet to be reached. Cardiac rehabilitation is mainly offered after an acute cardiac event and bypass surgery. It is also indicated in severe heart failure and special cases of percutaneous coronary intervention. Most patients are men (>65%) and the age at which events occur is increasing. The benefits obtained during the 3-4 weeks after an acute event, and confirmed in numerous studies, are often later lost under 'usual care' conditions. Many attempts have been made by rehabilitation institutions to improve this deficit by providing intensive aftercare. One instrument set up to achieve this is the nationwide institution currently comprising more than 6000 heart groups with approximately 120000 outpatients. After coronary artery bypass grafting or acute coronary syndrome cardiac rehabilitation can usually be started within 10 days. The multidisciplinary rehabilitation team consists of cardiologists, psychologists, exercise therapists, social workers, nutritionists and nurses. The positive effects of cardiac rehabilitation are also important economically, for example, for the improvement of secondary prevention and vocational integration. PMID:17301623

    Cardiac tumours in infancy are rare and are mostly benign with rhabdomyomas, fibromas and teratomas accounting for the majority. The presentation depends on size and location of the mass as they tend to cause cavity obstruction or arrhythmias. Most rhabdomyomas tend to regress spontaneously but fibromas and teratomas generally require surgical intervention for severe haemodynamic or arrhythmic complications. Other relatively rare cardiac tumours too are discussed along with an Indian perspect...

    Gastric teratoma (GT) is a seldom seen congenital abnormality. GT always occurs in children. The greater curvature and posterior wall of the stomach are the most common sites involving GT. We diagnosed a case of GT located on the inferior wall of the cardiac orifice in a 20-year-old man. To the best of our knowledge, this is the first case of GT located on the wall of the cardiac orifice in an adult in the English literature. We report this unusual case as an addition to this rare disease usually found in children. Computed tomography combined with endoscopic ultrasonography can be selected to diagnose GT.

    In complex multicellular systems, such as the brain or the heart, the ability to selectively perturb and observe the response of individual components at the cellular level and with millisecond resolution in time, is essential for mechanistic understanding of function. Optogenetics uses genetic encoding of light sensitivity (by the expression of microbial opsins) to provide such capabilities for manipulation, recording, and control by light with cell specificity and high spatiotemporal resolution. As an optical approach, it is inherently scalable for remote and parallel interrogation of biological function at the tissue level; with implantable miniaturized devices, the technique is uniquely suitable for in vivo tracking of function, as illustrated by numerous applications in the brain. Its expansion into the cardiac area has been slow. Here, using examples from published research and original data, we focus on optogenetics applications to cardiac electrophysiology, specifically dealing with the ability to manipulate membrane voltage by light with implications for cardiac pacing, cardioversion, cell communication, and arrhythmia research, in general. We discuss gene and cell delivery methods of inscribing light sensitivity in cardiac tissue, functionality of the light-sensitive ion channels within different types of cardiac cells, utility in probing electrical coupling between different cell types, approaches and design solutions to all-optical electrophysiology by the combination of optogenetic sensors and actuators, and specific challenges in moving towards in vivo cardiac optogenetics.

    Conclusions: Obstructive sleep apnea is frequent, but unrecognized among patients undergoing CABG. In these patients, OSA is associated with prolonged intubation duration. Preventing these problems may be possible by early diagnosis and management of OSA in cardiac surgery patients. Further studies with larger sample of patients and longer follow-ups are required in this regard.

    Large pericardial effusion (LPE) leading to cardiac tamponade is a rare complication described in patients undergoing SCT. This complication is considered to be a manifestation of chronic GVHD; however its pathophysiology is poorly understood. Currently, there are no published data systematically describing the incidence, clinical characteristics and outcomes of LPEs in adult stem cell transplant recipients. We retrospectively evaluated 858 adult patients (512 autologous, 148 related and 198 unrelated donor) who underwent hematopoietic stem cell and BM transplants at our institution from 2005 to 2008 for the development of post transplant LPE. Seven patients (0.8%) were found to have LPEs and all these patients had undergone unrelated allografts. The median day of diagnosis post transplant was 229 (range 42-525). None of these patients had active manifestations of GVHD other than serositis at the time of LPE detection. Pericardial window (PW) was successfully placed in all patients who developed cardiac tamponade and most patients with LPE were effectively treated by increasing immunosuppression. We conclude that LPE is a rare late complication after allogeneic transplant in adults and in our study developed only after unrelated transplant. PW can be safely performed in these patients and LPEs can be successfully treated with intensification of systemic immunosupression.

Since it has been reported that tight BG control (80-110 mg/dL) yields better outcomes in critically ill patients, it became a standard of care to control BG using intravenous insulin infusion in ICU.

  1. Cardiac Alternans Arising from an Unfolded Border-Collision Bifurcation

    2007-01-01

    Following an electrical stimulus, the transmembrane voltage of cardiac tissue rises rapidly and remains at a constant value before returning to the resting value, a phenomenon known as an action potential. When the pacing rate of a periodic train of stimuli is increased above a critical value, the action potential undergoes a period-doubling bifurcation, where the resulting alternation of the action potential duration is known as alternans in the medical literature. Existing cardiac models treat alternans either as a smooth or as a border-collision bifurcation. However, recent experiments in paced cardiac tissue reveal that the bifurcation to alternans exhibits hybrid smooth/nonsmooth behaviors, which can be qualitatively described by a model of so-called unfolded border-collision bifurcation. In this paper, we obtain analytical solutions of the unfolded border-collision model and use it to explore the crossover between smooth and nonsmooth behaviors. Our analysis shows that the hybrid smooth/nonsmooth behavi...

    Full Text Available Introduction: Primary cardiac tumors are extremely rare in infants and children . Most primary cardiac tumors in pediatric age group are benign, and less than 10% of such tumors are malignant. Many of these tumors are asymptomatic and incidentally diagnosed. The clinical manifestations are very different and includes direct cardiac effect, systemic effect , and embolic phenomena. Every infant or child with an unusual cardiac murmur, unexplained congestive heart failure, or arrhythmia should be evaluated for cardiac tumors. Echocardiography has contributed significantly to the evaluation of these patients. Surgery is the only treatment for primary cardiac tumors that require intervention with a relatively good prognosis. Case Report: The patient was a 20 days old neonate presented with severe congestive heart failure. Evaluation of the patient showed primary cardiac tumor in the left atrium and ventricle. We recommended surgical removal of the tumor but her parents denied surgical intervention at all. Conclusion: After about one year follow up, congestive heart failure symptoms were controlled and the tumor size was decreased.

    Full Text Available The Heart Institute of the University of São Paulo, Medical School is a referral center for the treatment of congenital heart diseases of neonates and infants. In the recent years, the excellent surgical results obtained in our institution may be in part due to modern anesthetic care and to postoperative care based on well-structured protocols. The purpose of this article is to review unique aspects of neonate cardiovascular physiology, the impact of extracorporeal circulation on postoperative evolution, and the prescription for pharmacological support of acute cardiac dysfunction based on our cardiac unit protocols. The main causes of low cardiac output after surgical correction of heart congenital disease are reviewed, and methods of treatment and support are proposed as derived from the relevant literature and our protocols.
