Objective: to understand how family members and adult patients perceive the family's presence in emergency care. Method: qualitative study that used Symbolic Interactionism as a theoretical reference and the Data Grounded Theory as a methodological reference. Data collection took place in two emergency rooms, located in southern Brazil, between October 2016 and February 2017, through open interviews with four patients and eight relatives. Results: the relative presence in the emergency care was signified/perceived as positive, due to the benefits identified for patients, family members and health professionals. However, the experience was also marked by mishaps for the family-patient relationship, such as fear, doubts, anguish about the forced separation of family members and the experience of feelings of regret. Conclusion: due to the fact that the presence of the family in the emergency room is perceived as positive and beneficial, it is suggested that the health services, to the extent of their possibilities, implement this practice. However, such units need to be better prepared to mitigate the pitfalls faced by patients and their families.
