Catheter Tip

An oxygen electrode mounted in the tip of an umbilical artery catheter was used in 36 newborn infants with severe respiratory illnesses, 28 of whom survived. Thirty-seven electrodes were used. The median age at insertion was 4 hours (range, 30 minutes to 122 hours). Three electrodes failed to work and they were removed or replaced, and two could not be properly evaluated. Thirty-two electrodes functioned satisfactorily for 10 to 190 hours (mean, 75 hours) after a one-point calibration against blood sampled through the catheter. Twenty-two did not need recalibrating before they were removed after 10 to 190 hours (mean, 88 hours). Four of the remaining ten electrodes were recalibrated once after 33 to 97 hours and then functioned until removed 15 to 55 hours later. The other six electrodes failed after 32 to 105 hours (mean, 49 hours). Complications were few. A total of 356 arterial blood samples, obtained after the initial calibration and before any recalibration was necessary, gave a correlation coefficient of 0.93 (P < .0001) against an independent system for measuring arterial oxygen tension (Pao2) (Radiometer Type E.5046 oxygen electrode). We conclude that the catheter-tip electrode is a safe and reliable instrument for continuously recording Pao2 in newborn infants which much simplifies the management of serious respiratory illnesses.

The Relationship

We studied nine healthy preterm infants during the first 35 days of life to define the relationship between periodic breathing, apnea, and hypoxia. For this purpose we compared ventilation/apnea (V/A), minute ventilation, and alveolar and capillary blood gases during periodic breathing induced by hypoxia and during spontancous periodic breathing in room air. We induced periodic breathing by giving the baby in sequence 21, 19, 17, and 15% O2 to breathe for 5 minutes each, and also by giving 21, 15, and 21% O2. We measured ventilation with a nosepiece and a screen flowmeter. With a decrease in arterial oxygen tension, preterm infants (1) hypoventilated, (2) breathed periodically more frequently, and (3) showed a decrease in V/A due to an increase in the apneic interval. In one baby this led to apnea lasting 30 seconds. These findings support our hypothesis that preterm infants breathing periodically hypoventilate and suggest that hypoxia may be a primary event leading to periodic breathing and apnea.
