Complicações clínicas em pacientes com trauma raquimedular cervical grave: estudo prospectivo de dez anos

OBJECTIVE: To determine the complications due to severe acrescentar sigla após o nome (CST). METHODS: Between 1997 and 2006, 217 patients (191 men and 26 women) were prospectively evaluated. The mean age was 36.75±1.06 years. RESULTS: Forty-five percent of the patients had medical complications. The most important risk factor was alcoholic beverage use. The most important associated injury was head trauma (HT). Patients with American Spine Injury Association (ASIA) A or B had a 2.3-fold greater relative risk of developing complications. Thirty-three patients (15.2%) died. Patients with neurological deficit had a 16.9-fold higher risk of death. There was no influence of age and time between trauma and surgery on the presence of complications. CONCLUSIONS: Of the patients, 45% had clinical complications and 7.5% had associated injuries; pneumonia was the most important complication; patient age and time between trauma and surgery did not influence the development of medical complications; neurological status was the most important factor in determining morbidity and mortality.OBJETIVO: Identificar complicações decorrentes do trauma raquimedular cervical grave. MÉTODOS: Avaliação prospectiva de 217 pacientes (191 homens e 26 mulheres) entre 1997 e 2006, com média de idade de 36,75±1,06 anos. RESULTADOS: Houve complicações em 45% dos pacientes. O fator de risco mais importante foi ingestão de bebida alcoólica. Trauma craniano foi a associação mais frequente. Pacientes com classificação A ou B da American Spine Injury Association (ASIA) tiveram 2,3 vezes maior chance de complicações. Faleceram 33 pacientes (15,2%), sendo a chance de óbito 16,9 vezes maior naqueles com déficit neurológico. Não houve influência da idade ou do tempo decorrido entre o trauma e a cirurgia. CONCLUSÕES: Dos pacientes, 45% apresentaram complicações e 7,5% apresentaram traumas associados; pneumonia foi a principal complicação clínica; a idade dos pacientes e o tempo entre o trauma e a cirurgia não influenciaram na frequência de complicações; o status neurológico após o trauma foi o fator de risco mais importante na determinação de morbidade e mortalidade.Conjunto Hospitalar do MandaquiUniversidade Federal de São Paulo (UNIFESP)Instituto de Assistência Médica ao Servidor Público Estadual Hospital do Servidor Público EstadualUNIFESPSciEL

Epidemiology of severe cervical spinal trauma in the north area of São Paulo City: a 10-year prospective study Clinical article

Object. the main objective was to study the epidemiological data obtained in patients with cervical spinal trauma (CST) in the north area of São Paulo City between 1997 and 2006.Methods. All patients with severe CST in the north area of São Paulo City were studied. the data analyzed were age, sex, incidence, causes of trauma, level of trauma, morbidity, deaths, and complications. Analytical tests were performed to study risks of trauma and complications. the chi-square and analysis of variance tests were used for analytical data (significance level p < 0.05).Results. the study population consisted of 217 patients who were hospitalized for CST. the average incidence rate was 21.6 cases annually or 1.8 cases monthly. the mean patient age was 36.75 years. the 20-40-year-old age bracket was found to be most highly represented, corresponding to 52.6% of total patients. Patients were predominantly male; 191 patients (88.01%) were male compared with only 26 female patients (11.99%). the ratio of men to women was 7.35:1. Injuries in the craniocervical region corresponded to 43 (19.8%) of the cases; injuries in the cervical subaxial region corresponded to 174 (80.2%) of the cases and were associated with worse neurological lesions. Additionally, 40.6% of patients presented with complications in other organs and systems; several patients presented with multiple complications, and 33 patients (15.02%) died. During the hospitalization period, 4 patients presenting as Grade A on the American Spinal Injury Association (ASIA) Scale evolved to Grade C, 1 patient presenting as ASIA Grade A evolved to Grade B, and 2 patients evolved to Grade E. Two patients who had been admitted without neurological lesions evolved to ASIA Grade C (1 patient postsurgery and 1 patient post-traction). Two patients presenting initially as ASIA Grade E evolved to Grade D, and another to central cord syndrome. On average, patients with incomplete lesions improved 1 grade in ASIA classification during hospitalization.Conclusions. Data from severe CST observed in the current study suggest many differences in the characteristics described in the majority of published epidemiological studies and those found in patients in the north area of São Paulo City. It is likely that these differences reflect the urban and cultural habits and behaviors of the population specific to this area.
