Description of intervention(s) / exposure
Compare three duration times (10, 15 and 20 minutes) of cryotherapy (ice pack) in healthy women. There are 3 groups of patients being compared in this study. Group 1 receives the ice pack for 10 minutes, Group 2 receives the pack for 15 minutes and Group 3 received the pack for 20 minutes in a previous study (is the control group: historical group). The packs were applied once (one session) for ten, fifteen and twenty minutes on the perineum within 2 hours after delivery. The packs, that measured 8cm wide by 16cm in length with a volume of 240ml, were involved in fine cotton fabric, to avoid direct contact with the skin. A digital Minipa (registered trade mark) model MT 405 thermometer was used to monitor the perineum temperature.

Outcomes
Primary outcome [1] 4710 0
To evaluate the best time (10, 15 and 20 minutes) of ice pack treatment for relief perineal pain. Pain magnitude was evaluated by the numeric scale represented by a horizontal line with numerical marks from zero to ten; the zero value denoted no pain and the ten values denoted the worst imaginable pain. We used a questionnaire developed to use in this particular research project where the women related the sensation during ice pack application, after the intervention.
Timepoint [1] 4710 0
In the group of 10 minutes- Ten minutes after the beginning of intervention
In the group of 15 minutes- Fifteen minutes after the begin of intervention
In the group of 20 minutes- Twenty minutes after the begin of intervention
