This pilot intervention study, with prospective data and a single intervention group, the outcome of which was the pain measured in women in labour, was designed to discuss the pain relief effects of cryotherapy in childbirth. The theoretical framework for this study was as described by Soares & Low, in which the mechanisms of the pain-relief action of ice foster decreased pain fibre transmission, reduced free nerve ending excitability, reduced tissue metabolism, increased pain fibre threshold and release of endorphins. It also drew on the principles of de-medicalisation and non-invasive obstetric nursing techniques as described by Vargens & Progianti. The study was conducted at the Obstetrics Centre of the Carmela Dutra Municipal Maternity Hospital, in Rio de Janeiro, from April to August 2011. Ice was applied using an adjustable belt-bag to the lumbar/thoracic region of 36 expectant mothers. The disposable TNT fabric belt-bag has an opening at the top for introducing plastic-wrapped ground ice. Applications were given at five centimetres cervical dilation; and/or at seven centimetres cervical dilation; and/or at nine centimetres cervical dilation: to a total of three applications over a 60-minute timespan, corresponding to the sum of 20 minutes each. The ice was produced exclusively for the project in the unit s freezer. Pain assessment data were collected by structured interview guided by a previously prepared script. The results provided evidence that cryotherapy produced extinction or relief of pain when applied to the lumbar-thoracic region of women in labour at five, seven or nine centimetres cervical dilation, affording them better conditions in which to experience their labour; it produced relaxation (both overall and locally, in the lumbar-thoracic region) in the women in labour; and it neither interfered in the dynamics of the uterus nor caused harm to the mother and child. It was concluded that cryotherapy, as described in this study, can be considered a non-invasive obstetric nursing technology for pain relief in labour.
