OBJECTIVE: Evaluate the Glasgow outcome scale (GOS) at discharge (GOS-HD) as a prognostic indicator in patients with traumatic brain injury (TBI). METHOD: Retrospective data were collected of 45 patients, with Glasgow coma scale <8, age 25±10 years, 36 men, from medical records. Later, at home visit, two measures were scored: GOS-HD (according to information from family members) and GOS LATE (12 months after TBI). RESULTS: At discharge, the ERG showed: vegetative state (VS) in 2 (4%), severe disability (SD) in 27 (60%), moderate disability (MD) in 15 (33%) and good recovery (GR) in 1 (2%). After 12 months: death in 5 (11%), VS in 1 (2%), SD in 7 (16%), MD in 9 (20%) and GR in 23 (51%). Variables associated with poor outcome were: worse GOS-HD (p=0.03), neurosurgical procedures (p=0.008) and the kind of brain injury (p=0.009). CONCLUSION: The GOS-HD was indicator of prognosis in patients with severe TBI.
-Introduction: Patients with severe brain lesions (SBL) and brain-dead patients (BD) frequently present with vasopressin (AVP) secretion disorders. Objective: To evaluate AVP serum levels in SBL and BD patients. Design: Prospective, open label, observational trial. Setting: A general teaching hospital. Method:Three groups of adult subjects (age ≥ 18y) of both sexes were included in this study: control group: 29 healthy volunteers; SBL group: 17 patients with Glasgow Coma Scale (GCS) ≤8; and BD group: 11 brain-dead patients. Samples of venous blood were collected in the morning at rest from healthy volunteers and at 8 hourly intervals over a period of 24h from SBL and BD patients for AVP determinations. Concomitantly, some clinical and laboratorial variables were also recorded. Results: AVP serum levels (pg/ml) were [mean (SD); median]: control [2.2(1.1); 2.0]; SBL [5.7(6.3); 2.9]; and BD [2.6(1.0); 2.8]. AVP serum levels varied greatly in SBL patients, but without statistically significant difference in relation to the other groups (p=0.06). Hypotension (p=0.02), hypernatremia (p=0.0001), serum hyperosmolarity (p=0.0001) and urinary hypoosmolarity (p=0.003) were outstanding in BD patients when compared with SBL. Conclusions: The AVP serum levels did not demonstrate significant statistical difference between the groups, only showing a greater variability in SBL patients (manifested as serum spike levels). Hypernatremia and hyperosmolarity were present in BD patients, indicating a failure of the hypothalamic-pituitary system in AVP production and release.KEY WORDS: brain lesion, brain death, vasopressin. Níveis séricos de arginina vasopressina em pacientes com lesão cerebral grave e em pacientes com morte encefálicaRESUMO -Introdução: Pacientes com lesão cerebral grave (LCG) ou com morte encefálica (ME) freqüentemente apresentam alterações na secreção de vasopressina (AVP). Objetivo: Avaliar os níveis séricos de AVP em pacientes com LCG e ME. Desenho: Estudo prospectivo, aberto, observacional. Local: Um hospital geral universitário. Método: Sujeitos adultos (idade ≥18 anos), de ambos os sexos, foram divididos em três grupos: grupo controle: 29 voluntários sadios; grupo LCG: 17 pacientes com pontuação na Escala de Coma de Glasgow (ECG) ≤8; grupo ME: 11 pacientes com diagnóstico de ME.Amostras de sangue venoso foram colhidas pela manhã, em repouso, nos pacientes do grupo controle, e de 8/8h, por 24h, nos pacientes dos grupos LCG e ME, para dosagens de AVP. Variáveis clínicas e laboratoriais de interesse foram anotadas concomitantemente. Resultados: Os valores da AVP (pg/ml) foram [média (DP); mediana]: grupo controle [2,2(1,1); 2,0]; grupo LCG [5,7(6,3); 2,9] e grupo ME [2,6(1,0); 2,8]. Observouse maior variação dos níveis séricos de AVP no grupo LCG, mas sem diferença estatisticamente significativa em relação aos demais (p=0,06). Hipotensão (p=0,02), hipernatremia (p=0,0001), hiperosmolaridade sérica (p=0,0001) e hiposmolaridade urinária (p=0,003) foram proeminentes no grupo ME em relação ao grupo LCG. Con...
-Background: cerebral salt wasting syndrome (csWs), syndrome of inappropriate antidiuretic hormone secretion (sIADH) and diabetes insipidus (DI) are frequently found in postoperative neurosurgery. Purpose: to identify these syndromes following neurosurgery. Method: the study included 30 patients who had been submitted to tumor resection and cerebral aneurysm clipping. sodium levels in serum and urine and urine volume were measured daily up to the 5 th day following surgery. Plasma arginine vasopressin (AVP) was measured on the first, third and fifth days post-surgery. Results: csWs was found in 27/30 patients (90%), in 14 (46.7%) of whom it was associated with a reduction in the levels of plasma AVP (mix syndrome). sIADH was found in 3/30 patients (10%). there was no difference between the two groups of patients. Conclusion: csWs was the most common syndrome found, and in half the cases it was associated with DI. sIADH was the least frequent syndrome found.Key WorDs: cerebral salt wasting syndrome, syndrome of inappropriate antidiuretic hormone secretion, diabetes insipidus, mixed syndrome, neurosurgery.Síndromes relacionadas com alterações de sódio e arginina-vasopressina no pós-operatório de neurocirurgia resUMo -Introdução: A síndrome perdedora de sal (sPs), síndrome da secreção inapropriada do hormô-nio antidiurético (sIADH) e diabetes insipidus (DI) são freqüentemente encontradas no pós-operatório de neurocirurgia. Objetivo: Identificar essas síndromes relacionadas à neurocirurgia. Método: Foram estudados 30 pacientes submetidos à ressecção de tumor (n=19) e clipagem de aneurisma (n=11) cerebral durante os primeiros cinco dias do pós-operatório. os pacientes foram submetidos a dosagens diárias de só-dio sérico e urinário até o 5º dia pós-operatório, com controle de volume urinário neste período e dosagem de arginina-vasopressina (AVP) plasmática no 1º, 3º e 5º dias pós-operatórios. Resultados: A sPs foi encontrada em 27/30 pacientes (90%), em 14/27 (46,7%) associada à diminuição dos níveis de AVP plasmá-tica (síndrome mista). A sIADH foi encontrada em 3/30 pacientes (10%). Não houve diferença entre os dois grupos de pacientes. Conclusão: A sPs foi a síndrome mais freqüente, em metade de casos associada ao DI. A sIADH foi a menos freqüente.PAlAVrAs-cHAVe: síndrome perdedora de sal, síndrome de secreção inapropriada de hormônio antidiurético, diabetes insipidus, síndrome mista, neurocirurgia.
