The effect of circumcision on transcutaneous PO2 in term infants.
To assess the effect of pain on PaO2 in newborns, transcutaneous PO2 (tcPO2) was monitored in ten healthy male infants undergoing circumcision. The tcPO2 was seen to decrease to a lower level with pain and to remain low with continuing pain. After the circumcision, the tcPO2 increased to levels equal to or exceeding those of the preoperative baseline period. Close corcordance of tcPO2 above and below the waist demonstrated no right-to-left shunting through the ductus arteriosus.

The Siemens-Elema Servo Ventilator 900 B for the management of newborn infants with severe respiratory distress syndrome: a 22-month trial.
The Siemens-Elema Servo Ventilator 900 B is an electronically-controlled, volume-limited ventilator. To adapt this ventilator for use in newborns with respiratory failure, minute volume control, PEEP valves, air-oxygen blenders, and respiratory tubing circuits were modified. During a 22-month period, 161 newborn infants with severe respiratory distress syndrome (RDS) were managed with this ventilator. The overall survival rate was 66%; the incidence of barotrauma was 20%; the survival rate was 53%. Of the infants studied, 12% developed bronchopulmonary dysplasia, and 79% of these survived. Of the 19% of patients with a symptomatic intraventricular hemorrhage, 6% survived. The experience of the authors with this ventilator modified to manage newborn infants with severe RDS has been extremely encouraging. Furthermore, this ventilator is versatile because it can be readily recalibrated for use in older patients and can be easily adapted for patients requiring surgery. This ventilator has the extremely important advantage of being a volume ventilator which can effectively provide positive pressure ventilatory support to patients of all age and weight groups.
