Abstract

Abstract: Introduction: Having a healthy child is one of the most important aims of pregnancy care. For decreasing fetus and infant morbidity and mortality rate, perinatal assessment such as non-stress test is required. It is one of the screening tests for fetal surveillance. It's advantages include: being noninvasive, painless, without risk to mother or fetus, no contraindication, short duration of conducting test, used for out and hospitalized patients, easy to do as well as availability of results immediately. Maternal position is one of the factors which affect the results of non-stress test. The relationship between maternal position and results of non –stress test was evaluated among high risk pregnant women hospitalized in Al –Zahra treatment educational center of Tabriz in 2003. Material and Methods: This is a clinical trial study in which 150 patients with singleton pregnancy at 32 to 42 week's gestation. Sampling method was nonprobability purposive. Data gathering tools were check list and sample select form. First patient was randomly assigned to a "sitting first" (semi –Fowler position) or "supine first" (left lateral position) and then position was alternated. Fetal heart rate monitoring was performed for ten minutes in each position. For data analysis, descriptive statistics (means, standard deviation) and analytic statics (chi squared test, Mcnemar test) were used. Results: There was no significant correlation between maternal positions and results non-stress test (p=0.05). Conclusion: According to the results, using of both position for performing non-stress test is suggested.
