Avaliação da aplicação do índice de tobin no desmame da ventilação mecânica após anestesia geral

Abstract: JUSTIFICATIVA E OBJETIVO:O índice preditivo de descontinuação da ventilação mecânica é parâmetro de prognóstico de desmame. O objetivo deste estudo foi avaliar a aplicação do índi-ce de Tobin antes da extubação traqueal em pacientes submetidos à anestesia geral. MÉTODO:Foram analisados 80 pacientes, 40 (50%) homens e 40 (50%) mulheres submetidos a colecistectomia sob anestesia geral. A média de idade foi 57,7 ± 12,4 (33 a 82 anos) e a média do peso corpóreo foi 70,85 ± 11,07 (48 a 90 kg). Trinta e sete (46,2%)… Show more

“…According to the literature, successful extubation might be influenced by factors such as age, duration of MV, hemoglobin concentration, arterial carbon dioxide partial pressure, amount of endotracheal secretions, and particularly among neurological patients, airway protection and patency parameters, (9,10,21-23,25,26) which might have interfered with the results of the present study. Although the ability to wean patients off mechanical ventilation is assessed in a similar manner in patients with and without neurological disorders, the assessment of the risk of extubation failure is not equally well standardized.…”

“…The main advantages of these measures are that they can be obtained at the bedside with portable devices (ventilometer), is easily reproducible, can be performed in a short period of time, is non-invasive and without the need for any laboratory data. This index can be useful to reduce the failure of the premature weaning and to eliminate the delay in the weaning of patients potentially able to be dispensing from the ventilatory support 18 . The calculation of RSBI can be performed using the values provided by the ventilator display, but is not yet an established routine in ICUs due to the fact that the pressure for ventilatory support, even small, still offers aid to the inspiration of the patient, saving some work.…”

“…Esses resultados controversos em relação à eficácia do índice em populações específicas têm estimulado alguns autores a discordar da padronização de um único ponto de corte para as diferentes populações e gravidade dos indivíduos, surgindo assim, estudos que sugerem novos pontos de corte para diferentes populações (KRIEGER et al, 1997;MANTOVANI et al, 2007;DANAGA et al, 2008;BOUTOU et al, 2010;VIDOTTO et al, 2008).

“…Já para os parâmetros de mecânica pulmonar, alguns índices são muito utilizados na tentativa de guiar a decisão da retirada da VM, destacando-se as medidas de P.0,1, P.01/PImax, PImax, PEmax, CV, quantidade de secreção, índice de CROP, IRRS (YANG; TOBIN, 1991;CAPDEVILA et al, 1995;VALLVERDÚ et al, 1998;ZEGGWAGH et al, 1999;NGUYEN et al, 2006;AFESSA;HOGANS;MURPHY, 2006;SU et al, 2010;MANTOVANI et al, 2007).…”
