“…Glomerular function declines with age, but studies show that renal failure during heart surgery is a frequent complication; noted more often when CPB time exceeds 90 minutes, confirming the findings of the sample [26][27][28].…”

O efeito do índice de massa corporal sobre as complicações no pós-operatório de cirurgia de revascularização do miocárdio em idososThe effect of the body mass index on postoperative complications of coronary artery bypass grafting in elderly Abstract Objectives: To evaluate the effect of BMI (body mass index) in the postoperative period of elderly patients undergoing CABG.Methods: Cross-sectional retrospective study, carried out in academic hospital, with all patients (n=290), aged or above 60 years, undergone CABG, from August 2006 to July 2007. The patients were divided into tertiles of BMI (<22, 22-27,> 27kg /m²). The variables included in the study were collected from medical records of patients and analyzed by logistic regression in association with the categories of BMI.Results: In the group with malnutrition were found larger percentage of impaired lung, kidney, hospital stay and immediate surgical mortality; but without statistical significance. Among female patients, the group malnutrition and eutrophy, 61.5% had hospital stay for a period longer than seven postoperative days compared to 42.5% male patients (p=0.003). In the group with malnutrition was found association between the CPB time and renal dysfunction with p<0.001 and, in eutrophic group with p=0.04. Obesity obtained protective association for lung dysfunction (RR=0.99), readmissions (RR=0.45) and mortality (RR = 0.77), and risk factor for renal dysfunction (RR=1.12).

“…[13,17,18] Because there was no increase in its levels, we can assume that there was no clinically significant decrease in GFR during the study period in either group. The Cochrane meta-analysis of effects of nonsteroidal anti-inflammatory drugs on postoperative renal function in adults with normal renal function did not find any clinically meaningful difference between NSAIDs and placebo.…”

“…Severe renal hypoperfusion, if not corrected, will ultimately lead to ischemic ATN 8 . The oxygen tension in the renal cortex is about 50 mmHg higher than that of the inner medulla, as a result of heterogeneity of flow and oxygen requirement 9 . Medullary oxygenation is strictly balanced by a series of control mechanisms, which match regional oxygen supply and consumption.…”

Purpose: To study in rats the effect of S(+)-ketamine on the renal histology after intraoperative hemorrhage. Methods: Twenty male Wistar rats, anesthetized with sodium pentobarbital, were randomly divided in 2 groups: Gl -control (n=l0) and G2 -S(+)-ketamine (n=10), both submitted to arterial hemorrhage of 30% of volemia in 3 moments (10% each 10 min) 60 min after anesthesia. G2 received S(+)-ketamine, 15 mg. kg-1, i.m., 5 min after anesthesia and 55 min before the 1 st hemorrhage moment (Ml). Medium arterial pressure (MAP), rectal temperature (T) and heart rate were monitored. The animals were sacrificed in M4, 30 min after the 3 rd hemorrhage moment (M3) and the kidneys and blood collected from hemorrhage were utilized for histological study and hematocrit (Ht) determination. Results: There were significant reduction of MAP, T, and Ht. The histological study verified G1 = G2 for tubular dilation, congestion, and necrosis. The total score addition were significant1y different and G2 > G 1. Conclusion: Hemorrhage and hypotension determined changes in kidney histology. The rise in catecholamine blood concentration probably was the cause of S(+)-ketamine-induced higher score of histological changes. Key words: Anesthesia and Analgesia. Pentobarbital. Kidney. Ischemia. Hemorrhage. Hypotension. Hypovolemia. RESUMOObjetivo: Investigar, em ratos, o efeito da S(+)cetamina na histologia renal após hemorragia intra-operatória. Métodos: Vinte ratos Wistar machos, anestesiados com pentobarbital sódico, foram divididos, aleatoriamente, em 2 grupos: G1 -controle (n=10) e G2 -S(+)cetamina (n=10), submetidos a hemorragia de 30% da volemia em 3 momentos (10% a cada 10 min) 60 min após anestesia. G2 recebeu S(+)cetamina, 15 mg. kg -1 , i.m., 5 min após anestesia e 55 min antes do 1. o momento de hemorragia (M1). Foram monitorizadas a pressão arterial média (PAM), temperatura retal (T) e freqüência cardíaca. Os animais foram sacrificados (M4) 30 min após o 3. o momento de hemorragia (M3). Os rins e o sangue das hemorragias foram utilizados para estudo histológico e do hematócrito (Ht). Resultados: Houve redução significativa da PAM, T e Ht. Na histologia, G1=G2 na dilatação tubular, congestão e necrose. A soma total dos escores foi significativamente diferente e G2>G1. Conclusão: Hemorragia e hipotensão determinaram alterações na histologia renal. O aumento da concentração sangüínea de catecolaminas provavelmente determinou escores mais altos de alterações histológicas com o uso de S(+)cetamina.
