In the mobile pre-hospital environment such as the SAMU, the nurse has several functions in the areas of care, administration, operation and supervision, and must participate in the review of protocols and provide training for the other professionals in the team. Despite this, changes have been taking place over the years in relation to the performance of nursing, improving legal aspects and increasing the autonomy of nurses. The general objective of the research is to analyze the role of nurses in urgent and emergency mobile pre-hospital care, and as specific objectives to describe the nurse's attributions as a member of the urgent and emergency mobile PHC service team, to point out the difficulties and challenges exist in the nurse's work and discuss the importance of the nurse in the mobile emergency APH. Thus, the present work is an integrative literature review, using the following descriptors: “emergency assistance”, “pre-hospital care” and “emergency nursing”. The work was prepared between February and May 2022, using studies published between 2012 and 2022. Such works were found in the SCIELO, LILACS and MEDLINE databases. As a result, the nurse must act as an advisor by participating in the review of protocols, in the elaboration and organization of educational content and as a professional of the multidisciplinary team of accidents and disasters. However, the nurse in the PHC has been exposed to unfavorable ergonomics, low salaries, exhausting workload, influencing their physical and mental health. Thus, the role of nurses in the PHC is still fragmented, developing little autonomy, despite being extremely important in the composition of the team, as it promotes assistance, management, education, leadership and humanization. Still, the need for continuing education with realistic theoretical-practical training for SAMU nurses was proved, with an emphasis on mental health for patients in psychiatric crisis.

The gestational period is characterized by several changes in the female body, which come from mechanical and/or hormonal activities. A number of changes take place with the main objective of maintaining and facilitating the healthy development of the fetus. Low back pain is one of the main musculoskeletal complaints referred to during pregnancy, and it is estimated that more than 50% of pregnant women are affected by low back pain, especially in the third trimester of pregnancy. Physiotherapy, through kinesiotherapy and the Pilates method, enables the treatment of gestational low back pain, as well as the prevention of this disorder. Thus, the general objective of the research is to investigate the benefits of the Pilates method and kinesiotherapy in pregnant women with low back pain. Therefore, the specific objectives are to know the biomechanical changes of the gestational period, to understand the most common pathological changes that occur in the pregnancy period, to understand the so-called gestational low back pain, to know about the importance of physiotherapy in the care of pregnant women and to learn about the Pilates method and kinesiotherapy applied in this phase of female life. It is, therefore, an integrative review of the literature of a qualitative nature, and, for its preparation, the following descriptors were used: "Pregnant women", "Lumbar pain", "Pilates method", "Exercise therapy" in Portuguese , English and Spanish. The work was produced in the year 2022, between the months of March and May. The years 2012 to 2022 were established as a delimitation, with emphasis and preference being given to research from the last 5 years. The databases consulted were: Scientific Electronic Library Online (SciELO), PEDRo and the Virtual Health Library (BVS). The main finding of this research was the evidence that the Pilates method is extremely superior to the non-treatment used by the control groups of randomized clinical trials for the treatment of gestational musculoskeletal pain. The Pilates method was also beneficial for controlling the progression of diastasis, increasing mobility, functionality and functional capacity, increasing strength and resistance of the abdominal and pelvic floor muscles. It was also evidenced that the regular practice of physical exercises is recommended for pregnant women, being the moderate intensity, the duration of 150 minutes per week distributed in the frequency of 3 days a week, in sessions that vary between 30 and 60 minutes. Furthermore, it is concluded that kinesiotherapy and the Pilates method have been applied for the treatment and prevention of gestational low back pain. Both are necessary for the improvement of physical conditioning, sleep improvement, pain relief and musculoskeletal discomfort caused by the gestational process.
