“…A literature review discussed the main factors involved in neurological injury following cardiac surgery and assessed the pharmacotherapy used to prevent it (28). This study indicates that ECC and perfusion time is an intraoperative risk factor associated with the duration of the procedure.…”

Introduction: Cardiovascular diseases are a serious public health problem in Brazil. Myocardial revascularization surgery (MRS) as well as cardiac valve replacement and repair are procedures indicated to treat them. Thus, extracorporeal circulation (ECC) is still widely used in these surgeries, in which patients with long ECC times may have greater neurological deficits. Neurological damage resulting from MRS can have devastating consequences such as loss of independence and worsening of quality of life. Objective: To assess the effect of cardiac surgery on a patient's mental state and functional capacity in both the pre-and postoperative periods. Methods: We conducted a cross-sectional study with convenience sampling of subjects undergoing MRS and valve replacement. Participants were administered the Mini-Mental State Exam (MMSE) and the Duke Activity Status Index (DASI) in the pre-and postoperative periods, as well as before their hospital discharge. Results: This study assessed nine patients (eight males) aged 62.4 ± 6.3 years with a BMI of 29.5 ± 2.3 kg/m

“…Of the risk factors involved in neurocognitive dysfunction in the perioperative period, three specifically stand out: age, educational level, and previous diseases. Particularly important risk factors in the intraoperative period are as follows: embolus formation; CPB time; air bubbles originating from the oxygenator; blood pressure level; and the temperature elevation that may occur in the postoperative period 16 , 17 .…”

BackgroundCoronary artery bypass graft (CABG) is a standard surgical option for patients with diffuse and significant arterial plaque. This procedure, however, is not free of postoperative complications, especially pulmonary and cognitive disorders.ObjectiveThis study aimed at comparing the impact of two different physiotherapy treatment approaches on pulmonary and cognitive function of patients undergoing CABG.MethodsNeuropsychological and pulmonary function tests were applied, prior to and following CABG, to 39 patients randomized into two groups as follows: Group 1 (control) – 20 patients underwent one physiotherapy session daily; and Group 2 (intensive physiotherapy) – 19 patients underwent three physiotherapy sessions daily during the recovery phase at the hospital. Non-paired and paired Student t tests were used to compare continuous variables. Variables without normal distribution were compared between groups by using Mann-Whitney test, and, within the same group at different times, by using Wilcoxon test. The chi-square test assessed differences of categorical variables. Statistical tests with a p value ≤ 0.05 were considered significant.ResultsChanges in pulmonary function were not significantly different between the groups. However, while Group 2 patients showed no decline in their neurocognitive function, Group 1 patients showed a decline in their cognitive functions (P ≤ 0.01).ConclusionThose results highlight the importance of physiotherapy after CABG and support the implementation of multiple sessions per day, providing patients with better psychosocial conditions and less morbidity.

“…This evolution of new knowledge minimized the deleterious effects of CPB and with the addition of accessories such as arterial filters and bubble detectors; it has reduced the morbimortality in cardiac surgery procedures with CPB [38,[43][44][45]. However, the incidence, still frequent of neurological complications remains a challenge because, despite all the advances, neurologic complications still occur and are causes of serious damage [4].…”

Neurological complications are an important cause of morbidity in the postoperative period of cardiac surgery and its incidence reaches up to 75% of patients. An important cause of these events is the formation of microbubbles in the bloodstream during cardiopulmonary bypass. Integrative review was carried out on gaseous microemboli in cardiopulmonary bypass. This study analyzed studies with different methodological approaches, but that address the issue. The result suggests the denitrogenation of blood by hyperoxia dissolved microbubbles in the blood and venoarterial shunt can balance the respiratory parameters changed with hyperoxia.Descriptors: Extracorporeal circulation. Embolism, air. Cognition disorders. Cardiac surgical procedures. ResumoAs complicações neurológicas representam importante causa de morbidade no período pós-operatório de cirurgia cardíaca e sua incidência alcança até 75% dos pacientes. Uma importante causa desses eventos é a formação de microbolhas na corrente sanguínea durante a circulação extracorpórea. Realizou-se revisão integrativa sobre microembolia gasosa na circulação extracorpórea. Esse trabalho analisou estudos com abordagens metodológicas diferentes, mas que contemplam o tema. O resultado sugere que a desnitrogenação do sangue causada pela hiperoxia dissolve microbolhas formadas no sangue e o shunt venoarterial pode equilibrar os parâmetros respiratórios alterados pela hiperoxia.Descritores: Circulação extracorpórea.
