تاثير وضعيتهاي مختلف بدن و حالات مختلف اندازه گيري بر تغييرات فشار خون كودكان

The effect of body position and Sphygmomanometer cuff size on the measurement of blood pressure

مقدمه اطمينان از صحت اندازه گيري فشارخون مسالهاي حياتي ميباشد. هدف از مطالعه ي حاضر بررسي تغييرات فشار خون كودكان در وضعيت هاي مختلف بدن و سايز مختلف كاف فشارسنج ميباشد. روش كار در اين مطالعه كودكان سن 3 تا 12 ساله كه سابقه بيماري خاصي نداشته و جهت چكاپ به كلنيك بيمارستان دكتر شيخ مشهد مراجعه كرده بودند وارد مطالعه شدند. پس از اخذ رضايت آگاهانه از والدين، در شرايط بدون استرس و در حالت استراحت فشار خون اندازه گيري گرديد. كودكان به 5 گروه تقسيم شدند: در يك گروه فقط فشارخون ايستاده و نشسته، در گروه ديگر فشار خون به صورت خوابيده و نشسته، در يك گروه فشار خون با كاف كوچك و نرمال، در گروه ديگر فشار خون با كاف بزرگ و نرمال و در گروه آخر فشار خون از روي لباس (با قطر يكسان براي همه) و از زير لباس اندازه گيري شد. آناليز دادهها توسط نرم افزار SPSS نسخه 16انجام شد. نتايج 180 كودك مورد ارزيابي قرار گرفته كه فشار خون اندازه گيري شده با كاف كوچك به صورت معناداري بيشتر از كاف نرمال بود (0/001 > p) ، همچنين فشارخون اندازه گيري از روي لباس به طور قابل ملاحظهاي بيشتر از زير لباس بود (0/001>

Introduction: The purpose of this study was to examine the changes in children's blood pressure in different body positions and different measurement conditions. Materials and Methods: Children aged between 3 to 12 years who were referred to the Sheikh Children's Hospital's Clinic for regular check-up entered in to the study. The blood pressure of the subjects was measured. Patients were divided into 5 groups: in the first group only the blood pressure was measured in standing and sitting positions; in the second group, the blood pressure was measured in supine and sitting positions, in the third group the blood pressure was measured by small and normal cuff; in the fourth group, the blood pressure was measured by large and normal cuff, and in the last group, blood pressure was measured with and without patients' clothes on. Results: Overall 180 cases entered in to our study. A significant difference was found between blood pressure measured by small and normal cuff, so that the blood pressure measured by small cuff was significantly higher than that of the normal cuff (P <0.001) and also blood pressure measured on patients clothes was significantly higher than blood pressure measured under clothing (P <0.001), but there was no significant difference in blood pressure measured in standing and sitting positions, sitting and supine positions and Large cuff and normal cuff (P >0.05). Conclusion: The present study emphasizes the importance of choosing a suitable cuff and measuring blood pressure without covering in the upper extremity by clothes.
