Childbirth is usually a joyous occasion. However, a significant proportion of parents experienced traumatic childbirths and suffered post-traumatic consequences, which needs urgent attention. Therefore, this review aimed to explore and understand the traumatic childbirth experiences of parents. A systematic review of qualitative studies was done. The consolidated evidence was meta-summarized and meta-synthesized based on Sandelowski and Barroso’s approach for synthesizing qualitative research. Seven electronic databases, including PubMed, CINAHL, Embase, PsycINFO, Cochrane, Scopus, and Web of Science, were searched from each database’s inception to April 2020. Retrieved studies were screened using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and 19 studies were included in this review. All included studies were meta-summarized and meta-synthesized. An overarching theme, “traumatic birth: an evolving voyage,” with three main themes, (1) “proceedings to traumatic birth,” (2) “internal and external battles,” and (3) “muddling through to beating the odds,” and 10 subthemes were identified. Overall, parents felt fluctuations of emotions that seemed to be never-ending journeys. They expressed that various factors led to their traumatic birth experiences, especially health care providers’ dismissive attitudes. Parents commonly reported feelings of powerlessness and fear for the safety of mothers and infants. Their constant battles to overcome traumatic experiences affected some of their relationships. To deal with the trauma, some mothers displayed avoidance behaviors while others relied on social support. As health care providers play important roles in influencing outcomes of childbirth, they should be mindful of the care provided during labors and childbirths.
