Infecções em dispositivos neurológicos implantáveis em crianças e adolescentes

OBJETIVO: Determinar a freqüência, as causas, o sítio específico e as manifestações clínicas e laboratoriais das infecções em crianças e adolescentes após a implantação de dispositivos neurológicos (DVP) no Hospital Governador João Alves Filho (Aracaju SE). MÉTODO: Estudo prospectivo, observacional, não controlado de 50 pacientes, submetidos a DVP (58 procedimentos), no período de janeiro de 2003 a outubro de 2004. RESULTADOS: Observaram-se taxas de infecção por procedimento de 27,6%, taxas de infecção de índice cirúrgico zero, 1 e 2 de 25,7% e 30,4%, respectivamente (NNIS-CDC). A infecção de sítio cirúrgico foi a principal complicação com 50% das infecções. CONCLUSÃO: Taxa de infecção por procedimento, paciente e índice de risco cirúrgico mostraram-se elevadas. Não houve significância estatística com relação à idade, etiologia da hidrocefalia, ao tipo de procedimento (derivação primária e reinserção), tempo de internação pré-operatória, duração da cirurgia, antibioticoprofilaxia, cateter SNC prévio e índice de risco cirúrgico. _________________________________________________________________________________________ ABSTRACT: OBJECTIVE: To determine frequency, etiology, site and clinical and laboratory findings of ventriculoperitoneal shunt (VPS) infections in children and adolescents with hydrocephalus managed in Hospital Governador João Alves Filho, Aracaju SE, Brazil. METHOD: A non-controlled prospective observational study comprising 50 patients that underwent VPS (58 procedures) from January/2003 to October/2004. RESULTS: Infection rate per procedure was 27.6%; surgical risk index (NNISS-CDC) 0 and 1-2 were 25.7% and 30.4% respectively; surgical site infection was the main complication with 50% of the cases. CONCLUSION: Infection rates per procedure, per patient, and per surgical risk index were high. No statistical differences were found related to the following: age, etiology of hydrocephalus, type of procedure, pre-operative length of stay, duration of procedure, antibiotic prophylaxis, previous central nervous system catheter, and surgical risk index

EVALUATION OF SACCADIC EYE-MOVEMENTS AS AN OBJECTIVE TEST OF RECOVERY FROM ANESTHESIA

International audienceSaccadic eye movements have been previously used to assess residual effect of anaesthetics, but this test is seldom compared to other psychomotor tests. The aim of the present study was to validate saccades as a recovery index in relation to frequently referred subjective and psychometric tests. Eight healthy subjects were tested before and after intra-muscular injection of either placebo or 0.15 mg . kg(-1) of midazolam. Each session consisted of a saccadic rest (recorded by electro-oculography), a choice-reaction-time test (CRT), a subjective state-of-alertness test (11 visual analogic scales) and blood sampling (to monitor midazolam plasma concentration), before and 30 (t30), 60 (t60), 120 (t120), 180 (t180), 240 (t240) minutes after drug administration In the placebo group, there was no change in subjective assessment, saccade characteristics (latency, peak velocity and duration) or CRT results. In the midazolam group, 6 subjective items changed with different time-courses, when compared to baseline: from t30 to t120 (drowsy, in shape, tired, clumsy strong) and at t120 (woolly). Saccade latency and duration were significantly different from 130 to t120 and until t180 for peak velocity. CRT performance was significantly altered From t30 to t120. Midazolam plasma concentration decreased From 177+/-33 ng . ml(-1) at t30 to 47+/-12 ng . ml(-1) at t240. At this latter time, sensorimotor functions returned to the baseline. All subjects fulfilled the clinical conditions for home discharge 4 hours after administration. These results suggest that a saccadic eye movement test is a sensitive and reliable tool for the assessment of residual effect of anaesthetics. This test was found to be more sensitive than CRT test since peak saccadic velocity was the last psychometric parameter to be returned to baseline after midazolam injection. This study also confirms the poor reliability of subjective assessment, as subjects tended to underestimate the alteration of their performance immediately following drug injection
