“…The patients were submitted to the following surgeries, classified according to the literature as major surgeries 16 : gastrectomy, esophagectomy, colectomy, abdominoperineal amputation, sigmoidectomy, hepatectomy, duodenopancreatectomy, herniorraphy, transduodenal papillotomy and porta-azygos disconnection for varices.…”

“…Specifically, albumin is a protein synthesized by the liver, with a long mean life (21 days), hence variations in its concentration during a short interval can not be explained by nutrition or liver function alterations 17 . Some studies showed that serum albumin lower than 3 g/dl was followed by anergia as well as by more frequent and severe postoperative complications, and that parenteral nutrition improved the reactive state in delayed hypersensitivity skin test and decreased the number of postoperative complications 2,8,11,16,17 . Nevertheless, we did not find any publications evaluating albumin concentration in the immediate postoperative period.…”

-Background -The prevalence of protein-energy malnutrition in surgical patients is high, ranging from 10% to 54%. The correct assessment of the nutritional status of such patients is crucial since malnourishment is a risk factor for morbidity and mortality. Aim -To assess the effect of surgical trauma in serum albumin concentration during the immediate postoperative period of major surgeries. Methods -The study was conducted on 100 randomly chosen adult patients submitted to elective major surgeries, classified according to sex, age and skin color. Blood samples for the determination of serum albumin concentrations were obtained on the days before and after the surgical procedure. Results -There was a reduction in serum albumin from 3.72 ± 0.47 to 2.83 ± 0.71 g/dL (P< 0.0001) with no difference in sex or skin color for major surgeries. With respect to age groups, a greater drop in albumin was observed among patients aged over 65 years, followed by younger patients (< 45 years), and finally by patients aged 45 to 65 years. Conclusion -Major operations lead to acute reduction in albumin concentration in the immediate postoperative period, and it was more intense in patients aged over 65 years.RESUMO -Racional -A prevalência de desnutrição energético-protéica em pacientes cirúrgicos é alta, variando entre 10% a 54%. A correta avaliação do estado nutricional desses pacientes é crucial uma vez que a desnutrição é um fator de risco para a morbidade e mortalidade. Objetivo -Avaliar o efeito do trauma cirúrgico na concentração sérica de albumina, durante o período pós-operatório imediato de operações de grande porte. Métodos -O estudo foi conduzido em 100 pacientes escolhidos aleatoriamente adultos submetidos a procedimentos cirúrgicos eletivos de grande porte, classificados de acordo com sexo, idade e cor da pele. As amostras de sangue para a determinação da concentração sérica de albumina foram obtidas nos dias antes e após o procedimento cirúrgico. Resultados -Houve diminuição da albumina sérica de 3,72 ± 0,47-2,83 ± 0,71 g / dL (P <0,0001), sem diferença de sexo ou cor da pele para operações de grande porte. Com relação à faixa etária, a maior queda da albumina foi observada entre os pacientes com idade superior a 65 anos, seguidos pelos pacientes mais jovens (<45 anos) e, finalmente, pacientes com idade entre 45-65 anos. Conclusão -As grandes operações levam à diminuição aguda na concentração de albumina no pós-operatório imediato, que foi mais intensa nos pacientes com idade superior a 65 anos.

“…Thus, the offer of nutrients before, during or after an anesthetic procedure may be beneficial to patient undergoing surgery, resulting in a lower prevalence of postoperative co-morbidity [2] [3]. In parallel, the postoperative use of amino acid solutions reduces protein loss and/or improves the nitrogen balance after surgery [4].…”

Objective: Nutritional deficiencies are associated with increased morbidity and mortality during and after surgery. The present study evaluated nitrogen retention after transoperative intravenous infusion of amino acids and glucose. Design: Prospective study. Setting: Large community hospital. Patients: 18 randomly chosen patients undergoing medium or major surgeries. Interventions and Measurements: The experimental design included a 12-hour period before surgery (P1), a trans-operative period of 6 hours (P2), an early postoperative period (P3, 18 hours), and a late postoperative period (P4, 24 hours). Urinary amino acid and nitrogen were analyzed from P1 through P4. Group I, nine patients, received Ringer's lactate solution with 5% glucose, and Group II, another nine patients, received a 6.6% amino acid and 16.6% glucose solution over a 6-hour trans-operative period (P2) starting from the anesthesia procedures. All surgical procedures lasted a maximum of 3 hours. Results: There was no statistically significant difference in urinary amino acid or adrenaline excretion between P1 and P4 in either group. Nitrogen excretion values were also similar for both groups, i.e., 0.39 ± 0.16 and 0.39 ± 0.28 g/hour, respectively. The nitrogen balance showed greater nitrogen retention (−0.25 ± 0.24 g/hour) in the group receiving the amino acid infusion compared to the group receiving Ringer's lactate solution (−0.59 ± 0.26 * Corresponding author. E. T. Albuquerque-Filho et al. 1013g/hour) (P < 0.05). Blood plasma urea nitrogen and glycaemia did not increase at the end of the study (P4 period) in either group. Conclusion: These data indicate that trans-operative infusion of glucose and amino acids can be beneficial for patients submitted to surgical stress in terms of nitrogen retention.
