[Cryotherapy after childbirth: the length of application and changes in perineal temperature].

We present a descriptive study based on the data from two clinical trials conducted at a maternity hospital in São Paulo, Brazil, in 2008 and 2009. This study aimed to describe perineal temperature after the application of an ice pack during the postpartum period. Three groups of 38 postpartum women (n=114 total) received an ice pack between 2 and 48 h after delivery.
