چکیده
مقدمه: کلمپ دیررس بند ناف، به‌عنوان یکی از استانداردهای مراقبتی در زایمان طبیعی، به‌دلیل مزایای متعدد آن توصیه می‌شود. با این‌حال، زمان بهینه کلمپ بند ناف هنوز به‌طور قطعی تعیین نشده است، لذا مطالعه حاضر با هدف مقایسه پیامدهای مادری و نوزادی کلمپ دیررس و کلمپ فیزیولوژیک بند ناف انجام شد.
روشکار: این کارآزمایی بالینی تصادفی در سال‌های 1402-1400 بر روی ۳۰۰ زن باردار مراجعه‌کننده به زایشگاه نیک‌نفس شهرستان رفسنجان انجام شد. افراد به‌صورت تصادفی در دو گروه ۱۵۰ نفری قرار گرفتند. در گروه مداخله، کلمپ بند ناف به‌صورت فیزیولوژیک و در گروه کنترل، یک دقیقه پس از تولد انجام شد. سپس، دو گروه از نظر پیامدهای مادری و نوزادی مورد مقایسه قرار گرفتند. ابزار گردآوری داده‌ها شامل چک‌لیست اطلاعات دموگرافیک و مامایی، پرسشنامه ارزیابی تغذیه نوزاد با شیر مادر و پرسشنامهASQ بود. تجزیه ‌و تحلیل داده‌ها با استفاده از نرم‌افزار آماریSPSS (نسخه ۲۲) و آزمون‌های آماری مجذور کای، تی مستقل و منویتنی انجام شد. مقدارp کمتر از 05/0 معنادار در نظر گرفته شد.
یافته­ ها: دو گروه از نظر نمره آپگار در دقیقه اول و پنجم، تعداد ضربان قلب و تعداد تنفس نوزاد، مدت مرحله سوم زایمان، خونریزی پس از زایمان، نمره شیردهی، زردی نوزاد، نیاز به فتوتراپی و وضعیت تکامل کودک در ۶ ماهگی، تفاوت آماری معناداری با یکدیگر نداشتند (05/0<p).
نتیجه­ گیری: کلمپ بند ناف به‌صورت فیزیولوژیک و یک دقیقه پس از تولد، هر دو روش‌هایی ایمن هستند و تفاوت معناداری در پیامدهای مادری و نوزادی ایجاد نمی‌کنند. این یافته‌ها از انعطاف‌پذیری بیشتر در انتخاب زمان کلمپ دیررس بند ناف در زایمان‌های طبیعی حمایت می‌کند.

چکیده English

Introduction: Delayed cord clamping (DCC) is recommended as a standard of care in vaginal births due to its benefits. However, the optimal timing remains unclear; therefore, the present study was conducted with aim to compare maternal and neonatal outcomes in physiological cord clamping versus cord clamping.
Methods: This randomized clinical trial was conducted in 2021-2023 on 300 pregnant women referred to Niknafs Maternity Hospital in Rafsanjan, Iran. Participants were randomly placed two groups of 150 women per group. In the intervention group, physiological cord clamping was performed, whereas in the control group, the umbilical cord was clamped 1 minute after birth. Maternal and neonatal outcomes were subsequently compared between the two groups. Data were collected using a demographic and obstetric information checklist, the Breastfeeding Assessment Questionnaire, and the Ages and Stages Questionnaire (ASQ). Statistical analyses were performed using SPSS (version 22) and Chi-square test, Independent t-test, and Mann–Whitney test. P<0.05 was considered significant.
Results: There were no significant differences between tw two groups regarding 1‑ and 5‑minute Apgar scores, neonatal heart rate or respiratory rate at 10 minutes, duration of the third stage of labor, postpartum bleeding, breastfeeding score, neonatal jaundice and need to phototherapy, or ASQ developmental status at 6 months (all p>0.05).
Conclusions: Both physiological cord clamping and cord clamping at 1 minute postpartum are safe methods, with no significant impact on maternal or neonatal morbidity. These findings support more flexibility in timing of delayed umbilical cord clamping in vaginal deliveries.
