Summary

Purpose: To examine the effects of straining techniques on the duration of labor, perineal trauma status and newborn apgar score. Method: This study is a randomized controlled trial. The straining techniques were explained to the pregnant women who gave written consent to participate in the study and were randomly assigned to groups in the latent phase (natural, spontaneous, Valsalva), and the techniques were applied in the second phase of labor.

Detailed description

Purpose: The present study was planned to determine the effects of straining techniques on the duration of labor, perineal trauma status, and newborn Apgar score. Method: The study, which had a randomized-controlled experimental design, was conducted in Sivas Numune Hospital Birth Unit. The sampling size was calculated using power analysis. In the literature, spontaneous straining is used by pregnant women in the range of 25-81%, and Valsalva -type straining has a rate of 32-75%. To represent the population of the study, sample volume was determined at =0.05 significance level, 1- =0.95 Confidence Interval, =0.20 error risk, and 1- =0.80 power, and the total number of individuals was determined as 354. The data of the study were collected with the "Pre-Evaluation Form", "Personal Information Form", "Labor Evaluation Form", and "Apgar Score" created by the researchers in line with the literature data. The straining techniques were explained to the pregnant women who gave written consent to participate in the study and were randomly assigned to groups in the latent phase (natural, spontaneous, Valsalva), and the techniques were applied in the second phase of labor. ANOVA, Kruskal Wallis H-test, Chi-square test, Exact test, Tamhane T2 test, and Dunn Test were used to evaluate the data obtained in the study. Statistical significance was evaluated at a 0.05 significance level and the SPSS version 23.0 was used.
