| Summary: | 碩士 === 國立台北護理學院 === 護理助產研究所 === 96 === This paper aims to study the effects of pushing immediately and delaying pushing during the second stage of labor on post-delivery tiredness as well as on delivery outcomes. Relevant data were collected from primiparous women over 37 weeks pregnant who were not given epidural analgesia during labor and did not have any complications in pregnancy. Surveys were conducted at a medical center and a regional hospital. A total of 72 responders were selected by convenient sampling and divided into an experimental group and a control group after the research purposes were explained. The Modified Fatigue Symptom Checklist (MFSC) was used, 1 hour and 24 hours after delivery, to measure the responders’ levels of fatigue (from 1 to 10 on the scale). Delivery outcomes of the experimental and control groups were analyzed according to their case histories. The SPSS 12.0 and SAS 9.1 statistics software were used to analyze the variables, and the findings are:Fatigue/ 1 hour after delivery: experimental group 2.08±1.87 minutes; control group 4.17±2.6 minutes; p<.01 referring to a significant difference. Fatigue/ 24 hours after delivery: experimental group 1.47±1.66 minutes; control group 3.36±2.13 minutes; p<.01 referring to a significant difference. Duration of second-stage labor/ experimental group 70.31±37.17 minutes; control group 129.06±75.69 minutes; p<.01 referring to a significant difference. Duration of push-off phase/ experimental group 47.53±30.85 minutes; control group 123.19±73.93 minutes; p<.01 referring to a significant difference. In addition, when the Generalized Estimating Equations method (GEE) was used to control the three variables that indicated significant statistical differences according to SPSS results, i.e. fundal height, duration of second-stage labor, and duration of push-off phase, the two groups varied only in the level of post-delivery tiredness (with a difference of 1.54 minutes, p<0.01). Other results showed no significant differences. As for delivery outcomes, the findings suggested no significant differences (p>.05) in terms of operative vaginal delivery, the rate of caesarean section, perineal wound, severe postpartum hemorrhage, fever, meconium aspiration syndrome, and the Apgar score.
