We developed and evaluated a transducer holder and calibrated, spring-loaded applicator for the Ladd intracranial pressure monitor. The transducer holder/applicator combination allows reproducibility of application pressure and assures coplanarity of the transducer and the skin of the anterior fontanel. Measured transfontanel pressure (TFP) increased with increasing application pressure. Mean TFP was 9.1 +/- (SD) 2.6 cm H2O with an application pressure of about 10 g/cm2 in a group of healthy preterm and term infants at 6 h postnatal age. Birth weight, gestational age and mode of delivery did not affect TFP, allowing use of a single normative value and set of confidence limits in all infants at 6 h of postnatal age.
我们研发并评估了一种用于Ladd颅内压监测仪的传感器固定器以及经过校准的弹簧加载式敷贴器。该传感器固定器/敷贴器组合可使施加压力具有可重复性，并确保传感器与前囟皮肤共面。测量的经囟门压力（TFP）随施加压力的增加而升高。在一组出生后6小时的健康早产儿和足月儿中，施加压力约为10 g/cm²时，平均TFP为9.1±（标准差）2.6 cm H₂O。出生体重、胎龄和分娩方式均不影响TFP，这使得在出生后6小时的所有婴儿中可使用单一的标准值和置信区间。
