Hemos estudiado la tolerancia clínica, complicaciones, evolución de las pruebas de función respiratoria (PFR), gasometría arterial, hemoglobina (Hb), test de esfuerzo de 6 minutos (6 wt) y sensación subjetiva de disnea valorada por la escala visual analógica (VAS), en un grupo de 18 pacientes (17 obstructivos y uno restrictivo) incluidos previamente en un programa de oxigenoterapia continua domiciliaria (OCD) por gafas nasales, que aceptaron oxigenación portátil por catéter transtraqueal (CTT) desde 1988 hasta 1993. La tolerancia fue buena, no hubo complicaciones letales secundarias al CTT y se consiguió un excelente cumplimiento de la prescripción de la OCD. Se observó un deterioro de las pruebas de función pulmonar y una mejoría de la Hb y de la PaO2 con un importante ahorro de oxígeno (50%). El 6 wt no se deterioró al final del primer año, sin embargo empeoró notablemente al final del tercer año, a pesar de haberse preservado relativamente el deterioro de la función pulmonar. No se observó empeoramiento de la disnea valorada mediante VAS. Concluimos que la tolerancia al método fue buena, sin existir complicaciones relevantes. La OCD por CTT no evitó el deterioro de la obstrucción bronquial. La oxigenación de los pacientes fue mejor como lo demuestran la disminución de la Hb y la mejoría de la PaO2 observadas al final del primer año de seguimiento. La evolución del 6 wt muestra que para optimizar más los beneficios de la OCD por CTT es conveniente que los pacientes sigan un programa de rehabilitación pulmonar.

We studied clinical tolerance, complications, change in pulmonary function test results, arterial gasometrics, hemoglobin (Hb), 6 minute stress tests (6 wt) and subjective perception of dyspnea assessed on a visual analog scale (VAS) in a group of 18 patients (17 with obstructive disease and one with restrictive disease). These patients had previously been enrolled in a home oxygen therapy (HOT) program to deliver continuous oxygen therapy through nasal prongs, and had accepted portable oxygen therapy delivered by transtracheal catheter (TTC) from 1988 until 1993. Tolerance was good, there were no lethal complications of TTC, and excellent compliance with the prescribed HOT was achieved. Lung function test results worsened, while Hb and Pa02 improved and significant oxygen savings (50%) were achieved. The 6 wt test results had not worsened at the end of the first year but did so significantly at the end of the third year, in spite of a relative preservation of lung function. Dyspnea assessed on a VAS was not seen to worsen. We conclude that tolerance of the method was good and that no relevant complications occurred. HOT by TTC did not prevent worsening of bronchial obstruction. Oxygenation of patients was better, as shown by the decrease in Hb and the improvement in PaO2 at the end of the first year of monitoring. Changes in 6 wt showed that in order to achieve greater benefit from HOT by TTC, patients should follow a pulmonar) rehabilitation program.
