تأثير خفض مستوى شدة الضجة على معدل الأكسجة لدى الأطفال الخدج في قسم الحواضن
Abstract
يشكل قسم الحواضن الملاذ الآمن للخدج بعد خروجهم المبكر من رحم الأم. فهي تحتوي متطلبات الحياة الأساسية للخديج, لكنها مليئة بالضجة الصادرة عن إنذارات الأجهزة و كلام الفريق الصحي و رنين الهواتف, وإغلاق الأبواب. تتجاوز مستوى هذه الضجة ما نصحت به الأكاديمية الأمريكية لطب الأطفال في قسم الحواضن 45 dBA (decibel A-weighting). كما تحفز الضجة الجملة العصبية الودية مؤدية لعدم استقرار فيزيولوجي كاضطراب مستوى الأكسجة. وجدنا في هذه الدراسة التي أجريت على 30 خديج باختبار قبلي و بعدي أن متوسط الضجة خلال ساعة من المراقبة و عدم التداخل لخفض الضجة قد بلغ 67.2 dBA, وتناسب مستوى الأكسجة عكسا مع مستوى الضجة, و أن خفض الضجة لمدة ساعة من الزمن دون 45 dBA قد رفع متوسط الأكسجة بشكل ملحوظ. لذلك تشير هذه الدراسة إلى ضرورة جعل إجراءات خفض الضجة ضمن الممارسات التمريضية اليومية, و إجراء أبحاث لاحقة لدراسة تأثير الضجة على باقي مؤشرات الخديج الحيوية. Nursery ward is the safe place for premature after deliverey . It contains the basic requirements of life to him. but full of noise caused by alarms of devices, conversations of health team, ringing phones, and close the doors, exceeds what is recommended by the American Academy of Pediatrics in the Nursery wards 45 dBA (decibel A-weighting). Although it stimulates the autonomic system leading to physiologic instability like disorder in the level of oxygenation. We found in this study conducted on 30 premature with pre and post test, that the level of noise within first hour of non interventions reached 67.2 dBA, level of oxygenation inversely with noise level in it, and reduction of noise level under 45 dBA at second hour increases the oxygenation significantly. so we suggests to make reduce noise interventions within daily practices of nursing procedures, and subsequent research to study effect of noise on the rest of vital premature indicators.Downloads
