“…A major factor in the prevention of this occurrence is the provision of adequate humidification of the inspired gas. Our experience is that the F. and P. humidifier is the most efficient means available at present for this purpose (Fisk and Vonwiller 1972). Blockage of ETT's necessitating re-intubation was a common problem in infants.…”

“…There is evidence that dry gas will cause early metaplastic changes in tracheal mucosa whereas humidified gas will not (Toremalm 1961, Chalon, Loew and Malebranche 1972, Forbes 1973. In all our patients saturated gas was delivered to the endotracheal tube at a temperature of at least 32° C using the Fisher and Paykel humidifier (Spence andMelville 1972, Fisk andVonwiller 1972).…”

Permanent sequelae of nasotracheal intubation are uncommon, but acute ulceration and squamous metaplasia occur.Histological sections from the trachea and main bronchi were examined in 12 infants. A nasotracheal tube had been inserted during the first two weeks of life of these infants and had been in place for more than one week. In four cases the patient died some time (7 to 108 days) after extubation. Similar sections from patients who were not intubated, intubated only for attempted resuscitation, or intubated for several hours were studied for comparison. The sections were classified according to the degree of mucosal loss and metaplasia, and the extent of the lesions was estimated.Squamous change was seen in most sections from all 12 patients with the exception of one who died 57 days after extubation. Some respiratory epithelium was seen in all patients. In the eight patients who died while intubated, the changes were more marked in the right main bronchus than the left in seven, and more marked in the lower trachea than the upper in five. In the two patients intubated for several hours, in addition to mucosal loss, early metaplasia was seen.It is suggested that mucosal loss is replaced by the squamous metaplasia, and that trauma caused by suction catheters in the lower trachea and right main bronchus is more extensive than that due to the endotracheal tube itself.

“…We have used the Fisher and Paykel humidifier (Spence and Melville 1972). A thermistor senses the temperature of the delivered gas just before reaching the patient or before entry into a humidicrib (Fisk and Vonwiller 1972). This system was tested using an artificial compliance, variable between one and five ml/cm of water, with resistances of 200 and 1,000 cm of water per litre per minute.…”
