Objective: To investigate the relationship between preoperative vitamin D and albumin levels and postoperative quality of life in patients undergoing spinal surgery. Methods: Patients undergoing thoracic and lumbar spine surgery were evaluated in this prospective study. Their vitamin D and albumin levels were assessed before surgery and quality of life was measured by two questionnaires, Oswestry Disability Index (ODI) and Scoliosis Research , one year after the procedure. Data on infection occurrence and healing time were collected. Preoperative nutritional values and patients' quality of life were analyzed using the chi-square test and ANOVA for albumin and vitamin D, respectively. The relationship among nutritional status, healing time, and the occurrence of infection was evaluated by the Pearson correlation coefficient. Results: Forty-six patients were included and their mean nutritional values were 19.1 (6.6) ng/mL for vitamin D and 3.9 (0.6) g/dL for albumin [mean (standard deviation)]. No association was found between vitamin D and quality of life of patients measured by ODI (p=0.534) and SRS-22 (p=0.739) questionnaires. There was also no association between albumin levels and quality of life measured by ODI (p=0.259) and SRS-22 (p=0.076) questionnaires. No correlation was found between the healing time or occurrence of infection and nutritional values. Conclusions: There was no association between vitamin D and albumin levels and the surgical result, according to the patient's perception, besides the occurrence of complications with the surgical wound.Keywords: Spine; Serum albumin; Vitamin D; Surgical wound infection; Quality of life. 19,1 (6,6) ng/ml para vitamina D e 3,9 (0,6) g/dl para albumina [média (desvio-padrão)]. Não foi encontrada associação entre os níveis de vitamina D e qualidade de vida dos pacientes medidos pelos questionários ODI (p = 0,739). Também não houve associação entre níveis de albumina e qualidade de vida medidos pelos questionários ODI (p = 0,076 ODI (p = 0,739). También no hubo asociación entre los niveles de albúmina y la calidad de vida medidos por los cuestionarios ODI (p = 0,076)
RESUMO
Objetivo: Investigar a relação entre os níveis de vitamina D e albumina pré-operatórios e qualidade de vida pós-operatória em pacientes submetidos a cirurgia de coluna. Métodos: Pacientes submetidos a cirurgia de coluna nos níveis torácico e lombar foram avaliados neste estudo prospectivo. Seus níveis de vitamina D e albumina foram avaliados antes da cirurgia e a qualidade de vida foi medida por meio de dois questionários, Oswestry Disability Index (ODI) e Scoliosis Research Society -22 (SRS-22), um ano após o procedimento. Os dados sobre ocorrência de infecção e tempo de cicatrização foram coletados. Os valores nutricionais pré-operatórios e a qualidade de vida dos pacientes foram analisados usando o teste de qui-quadrado e ANOVA para albumina e vitamina D, respectivamente. A relação entre o estado nutricional e o tempo de cicatrização e a ocorrência de infecção foram avaliados pelo coe...
