Abstract
In our system the inspiratory airflow next to the tracheal tube is sensed by a “not wire” anemometer. The flow signal, signals from the pressure limited ventilator (MOG 2000, Ginevri, Rome) (PAW; Ti; Te) and the patient (thor. impedance), and a variable, triggering electrical thereshold are also displayed The response time was less than 10 ms. Synchronous interaction was documented in 98% ol about 2000 recorded breaths from 8 VLBW infants. So far 16 neonates weighing 500-1500g (in 9 = b. wt m 764g, range 500-1000; GA m 26 7 wks range 24-29 wks) received FTV (in 75% from the 1st day of life) 2 babies died al 4-19 days with sepsis and severe brain damage. Out of the 14 (87.5%) survivors, 11 (79%) were exlubated within day 8, and the remaining 3 within the first month of life. 9 patients were given surfactant, and 5 indomethacin PNX PIF were never observed. In the first 5 days of life, the average PIP was 17-20 cmH2O; the average MAP ranged from 5.8 to 6.5 cmH2O, the mean PCO2 ranged between 45 and 49 mmHg in the first 60 hours alter birth and increased slightly thereafter. In most infants effective respiratory support in the days following extubation was apparently achieved by FTV through specially designed nasal prongs. At 28 days of age the required FiO2 was = - 0 3 in 4 (31%) of the cases.
Conclusions: in the present small senes of VLBW infants. FIV was feasible even in the youngest and tiniest neonates, the survival rate was satisfactory, lung barotrauma was not apparent, and in most cases the age at extubation was quite low. In spite of this a disturbing incidence of chronic lung disease was observed. Italian CNR, Targ. Project FATMA, contr n 92.00032 PF 41.
