 Between 60-80 of women delivering their first baby need suturing due to perineal tears tears located to the area between the vagina and anus. Superficial perineal tears rarely cause long-term problems, but often lead to pain and discomfort immediately after birth. Deeper or severe perineal tears, involving the anal sphincter, may influence the womans quality of life. This is mainly due to long-lasting pain, discomfort and sexual dysfunction, and the fact that obstetric anal sphincter tear is the main cause of anal incontinence. Recent clinical intervention studies have shown that the incidence of severe obstetric perineal tears may be reduced by 50-70 by introducing a bimanual support technique of the perineum. In these studies all midwives and gynecologists were trained in the bimanual support technique. When it comes to training in new medical techniques in general, some studies have shown that use of animated instructions on mobile phones may be a good alternative to the more traditional hands-on or bedside teaching methods. In a global perspective, it is important to study the efficacy of mobile units for transferring of new knowledge, especially for use in resource constrained settings.
