Abstract

OBJECTIVE

To quantify and compare variations in oxygen saturation throughout the suctioning procedure (before, during, and after) using two endotracheal suction systems: open suction system (OSS) vs. closed suction system (CSS).

METHODS

A prospective randomized controlled study was carried out with 39 newborn infants of gestational age ≥ 34 weeks using pressure-limited, time-cycled, continuous-flow mechanical ventilators. The infants were classified into two groups according to ventilatory parameters: Group I was ventilated using positive end-expiratory pressure (PEEP) ≥ 5 cm H2O and mean airway pressure (MAP) ≥ 8 cm H2O; and Group II using PEEP < 5 cm H2O and MAP < 8 cm H2O.

RESULTS

No statistically significant differences were observed when OSS and CSS were compared in both groups. There was a statistically significant improvement in post-procedure oxygen saturation in both groups.

CONCLUSION

Both endotracheal suction systems can be used with no drawbacks of OSS in relation to CSS, provided the sample is similar to that of the present study.

摘要

目的

使用两种气管内吸引系统：开放式吸引系统（OSS）与封闭式吸引系统（CSS），量化并比较整个吸引过程（吸引前、吸引期间和吸引后）中氧饱和度的变化。

方法

对39例胎龄≥34周的新生儿进行前瞻性随机对照研究，使用压力限制、时间切换、持续气流机械通气。根据通气参数将婴儿分为两组：第一组使用呼气末正压（PEEP）≥5 cm H₂O和平均气道压（MAP）≥8 cm H₂O进行通气；第二组使用PEEP < 5 cm H₂O和MAP < 8 cm H₂O进行通气。
