The aim of this study was to describe operating theatre nurses' experiences of teamwork within the surgical team in regard to achieving patient safety. Safe surgery for patients is based on teamwork in a safe modus between the members in the surgical team. Operating theatre nurses contribute to safe surgery by professional perioperative nursing activities and by participation in teamwork in the surgical team. A qualitative descriptive design using narrative interviews with 16 operating theatre nurses in Sweden was chosen for increased understanding of their experiences of teamwork in regard to achieving patient safety. The findings are presented in three themes, illustrating teamwork in regard to achieving patient safety between the operating theatre nurses' and other professionals in everyday situations. From the operating theatre nurses' narrated experiences of teamwork, person-centred nursing care, interdependent collaboration and familiarity of the professionals' skills contributed to safe surgery. A brief meeting, unfamiliarity of professionals' skills, uncontrolled tantrums and experiences of exclusion were experienced as counteractive to patient safety. The operating theatre nurses managed demanding situations by diverse strategies to restore patient safety.
