AIM
This study evaluates the effects of endotracheal suctioning duration on cerebral oxygenation and physiological parameters in preterm infants in intensive care.
DESIGN
Prospective and observational study.
METHOD
In this study, 51 preterm infants born at 28-34 weeks of gestation in NICU were evaluated. Cerebral oxygenation was measured before, during, and after endotracheal suctioning with near-infrared spectroscopy. Pain levels of the infants were with N-PASS scale.
RESULTS
A negative correlation was found between the lowest cerebral oxygenation value during endotracheal suctioning and the duration of endotracheal suctioning. Cerebral oxygenation levels during endotracheal suctioning were lower than pre- and post-endotracheal suctioning levels. Higher cerebral oxygenation was observed in infants whose endotracheal aspiration time was less than 13 s. The duration of endotracheal suctioning was positively correlated with pain and cerebral oxygenation stabilization time.
CONCLUSION
Prolonged endotracheal suctioning duration negatively affects cerebral oxygenation in preterm infants. The study suggests an optimal endotracheal suctioning duration under 13 s.
IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Properly executed endotracheal suctioning, with the correct technique and knowledge, can alleviate the adverse physiological effects observed in preterm infants and contribute to routine nursing care in intensive care units.
REPORTING METHOD
This study has been reported in line with STROBE checklists.
PATIENT OR PUBLIC CONTRIBUTION
No patient or public contribution was required to design or undertake this research. Patients contributed only to the data collection.
IMPACT
This study contributes to defining the ideal endotracheal aspiration duration, as there is not enough data so far. It showed the effect of prolonged endotracheal aspiration time on cerebral oxygenation, pain and physiological parameters in preterm infants.
目的
本研究评估气管内吸引持续时间对重症监护室早产儿脑氧合及生理参数的影响。
设计
前瞻性观察性研究。
方法
本研究对51例在新生儿重症监护室出生、孕周为28 - 34周的早产儿进行了评估。采用近红外光谱法在气管内吸引前、吸引期间和吸引后测量脑氧合情况。采用N - PASS量表评估婴儿的疼痛程度。
结果
发现气管内吸引期间最低脑氧合值与气管内吸引持续时间呈负相关。气管内吸引期间的脑氧合水平低于吸引前和吸引后的水平。气管内吸引时间小于13秒的婴儿脑氧合水平较高。气管内吸引持续时间与疼痛及脑氧合稳定时间呈正相关。
结论
延长气管内吸引持续时间对早产儿脑氧合有负面影响。该研究表明最佳气管内吸引持续时间应在13秒以下。
对专业和/或患者护理的意义：正确实施气管内吸引，掌握正确的技术和知识，可减轻早产儿观察到的不良生理影响，并有助于重症监护病房的常规护理。
报告方法
本研究已按照STROBE清单进行报告。
患者或公众贡献
设计或开展本研究无需患者或公众贡献。患者仅参与了数据收集。
影响
由于目前数据不足，本研究有助于确定理想的气管内吸引持续时间。它显示了延长气管内吸引时间对早产儿脑氧合、疼痛和生理参数的影响。
