Abstract
Background & Objective: One of the most important principles in education is adopting a teaching method in concordance with objectives, contents and learners. Teaching and learning clinical skills is a challenging aspect of education in field of medicine and allied health profession. Some of the new researchers have shown that video-based instruction has many advantages in comparative to others. But in the domain of the psychomotor learning there is not enough evidence to show that video-based instruction is an effective teaching method. The current study has compared students learning in video-based and demonstration methods. Materials & Methods: An experimental study was conducted on 40 first year nursing and midwifery students. The students were randomly assigned to case (N=20) and control (N=20) groups based on the their course. The data were collected from a pre-test, a post-test and a questionnaire for demographic information. Pre-test was given 24 hours prior to the presentation sessions. Then each group has received one skill with video-based and another skill with demonstration. Skills included the dressing changing and surgical hand washing. After 24 hours post-test was taken with previous criteria. The differences between the pre-test and post-test scores were considered as they are at learning level. Results: The overall learning in the demonstration method was higher than the video-based method (P<0.05). However the scores of students in 2 methods was at acceptable level. The scores of students in the cognitive domain of hand washing by the demonstration were 16.20±1.5 and by the video-based method were 15.25±1. The scores of students in the psychomotor domain of hand washing by the demonstration was 16.85±1.4 and by the video-based method was 15.94±1.4 (P<0.05). The scores of students in the cognitive domain of dressing change by the demonstration was 25.60±1.8 and by the video-based method was 15.50±1. The scores of students in the psychomotor domain of dressing change by the demonstration was 16.78±1.3 and with the video-based was 16.12±1 (P<0.05). Conclusion: The results indicated that demonstration method is more effective in the students learning. However, both video-based and demonstration have led to the high level of cognitive and psychomotor learning. It could be concluded that video-based instruction can be an effective method for replacing the demonstration, especially when there is not access to demonstration, in addition according to the findings, video-based education is a effective methods for transporting knowledge, information and other topics in the cognitive domain. Therefore, considering the cost-effectiveness of video-based instruction and its ease of use, this method can facilitate education in where lack of experienced instructors and equipment is most pronounced.

Abstract
Background & Objective: In most cases, labor is accompanied with pain. Thus, decreasing labor pain is viewed as an important duty of midwives. In this regard, decreasing the duration of labor can be of value. Customarily midwives use drugs to shorten the duration of labor, but the effectiveness of some of the drugs has not been studied systematically. Among such widely used drugs are Atropine, Hyoscine and Promethazine. Materials & Methods: In this interventional research, the effects of these drugs on labor duration were studied. 160 multiparous women in active phase of labor were selected. 120 of the above women had been administered only one of the above-mentioned drugs and no drug had been administered to the remaining 40. According to the type of drug administered, the women formed three groups, with the women with no drugs administered making the 4th groups. Results: The 4 groups did not have any statistically significant difference with regard to variables such as age, occupation, education, infant sex, gestational age, infant birth weight, parity, fetal head position, and cervical dilatation at the beginning of our observation. The main result was that, the mean rate of cervical effacement (P<0.05) and descent of fetal head was not significantly different in the 4 groups. But the mean rate of cervical dilatation (P<0.05) was significantly different in the 4 groups. In women who had been given these drugs, the mean rate of cervical dilatation was lower than the women who had not been given any drugs. The mean duration of the first stage of labor was significantly different in 4 groups (P<0.05). With regard to the mean duration of the first stage of labor, it was also longer in women who had been given these drugs. The mean rate of 2nd stage of labor and 3rd stage of labor was not significantly different in the 4 groups. Conclusion: The use of these drugs can reduce the rate of labor progress and increase the risk of complications, it may also be a waste of prescribed drugs.
