“…Ademais, FC elevada é um sinal de compensação quando existe hipotensão, o que foi observado quando a concentração anestésica esteve mais alta (2,0% e 1,8%, principalmente) (HAMLIN, 1999). Essa diminuição da pressão arterial é um efeito esperado em anestesia com isofluorano (BERNARD et al, 1987) e, por mais que tenha ocorrido alteração reflexa da FC, não houve significância clínica, pois os valores encontrados estiveram dentro de limites aceitáveis (OLIVA & FANTONI, 2010).…”

“…Anaesthetic drugs and positive pressure ventilation may have relevantly influenced LV cavity dimensions in the TOE study population by affecting systemic vascular resistance, venous tone and venous return (30). The physiologic effects of general anaesthesia and positive pressure ventilation on LV cavity size were recently demonstrated in a magnetic resonance imaging study in healthy adults (10) and several echocardiographic studies in healthy subjects and in patients with cardiac disease (9,(31)(32)(33).…”

Objective: Normative values for left ventricular (LV) end-diastolic area (EDA) and diameter (EDD) for intra-operative transoesophageal echocardiography (TOE) have not been established. We aimed to define the ranges of LV EDA and EDD for intra-operative TOE examinations in patients undergoing coronary artery bypass graft (CABG) surgery. Methods: A MEDLINE search for studies reporting LV EDA and EDD in patients undergoing CABG surgery was performed. Individual-level data set from 333 anaesthetised and ventilated patients with preserved LV function (study population) was obtained from eight studies. EDA and calculated EDD in the study population were compared with summary EDD values obtained using transthoracic echocardiography (TTE) in two studies of 500 awake patients with coronary artery disease (CAD). Further, the influence of pre-specified factors on EDD was evaluated in a multivariate regression model. Results: The EDA and EDD values measured using TOE in the anaesthetised CABG patients were 16.7±4.7 cm 2 and 4.6±0.6 cm, respectively. TOE values of EDD in anaesthetised patients were 10%-13% less than those measured using TTE in two studies of awake patients (p<0.001). Body surface area, age and fractional area change, but not sex were factors that affected LV EDD. Conclusion:The values for LV EDD measured through intra-operative TOE in anaesthetised ventilated CABG patients were 10%-13% less than the corresponding values measured using TTE in awake CAD patients. This finding indicates that independent normative values specific for intra-operative TE should be established for guiding intra-operative clinical decisions. Keywords: Echocardiography, transthoracic echocardiography, transesophageal echocardiography, cross-sectional, coronary artery bypass surgery Amaç: İntraoperatif transözofajiyal ekokardiyografi (TOE) için sol ventrikül (SV) diyastol sonu alanı (EDA) ve çapının (EDD) normal değerleri belirlenmemiştir. Bu çalışmanın amacı, koroner arter bypass greft (KABG) ameliyatı geçiren hastalarda yapılan intraoperatif TOE incelemeleri için SV EDA ve EDD aralıklarını tanımlamaktır. Yöntemler: KABG ameliyatı geçiren hastalarda SV EDA ve EDD değerlerini rapor eden çalışmalar için bir MEDLINE araştırması yapıldı. Korunmuş SV fonksiyonu olan 333 anestezi ve ventilasyon uygulanmış hastanın (çalışma popülasyonu) bireysel verileri 8 çalışmadan elde edildi. Çalışma popülasyonundaki EDA ve hesaplanmış EDD değerleri, koroner arter hastalığı (KAH) olan 500 bilinçli hastayı içeren iki çalışmada transtorasik ekokardiyografi (TTE) kullanarak elde edilen özet EDD değerleri ile karşılaştırıl-dı. Ayrıca, önceden belirlenmiş faktörlerin EDD üzerindeki etkisi multivaryant regresyon modeli kullanılarak değerlendirildi. Bulgular: Anestezi altındaki KABG hastalarında TOE kullanılarak ölçülen EDA ve EDD değerleri sırasıyla 16,7±4,7 cm 2 ve 4,6±0,6 cm olarak bulundu. Anestezi uygulanan hastalarda TOE ve EDD değerleri, bilinçli hastalar üzerinde yapılan iki çalışmada TTE kullanılarak ölçülen değerlere göre %10-%13 daha düşüktü (p<0,00...

“…The use of SNP did not affect the results of postoperative tests of cerebral, hepatic, or renal function and myocardial status in total hip arthroplasty [34]. SNP-induced hypotension produced increases in cardiac output, oxygen consumption, and intrapulmonary shunt during total hip arthroplasty [42]. In regard to renal function, Behnia et al [43] reported that renal medullary tissue oxygenation might remain adequate in spite of a significant decrease in endogenous creatinine clearance during the SNP-induced hypotensive period.…”
