The present exploratory study measured pain and tactile thresholds in response to mechanical stimulation of the hand before labor, during labor, and after parturition in women. In women who had Lamaze childbirth preparation (but not in women who did not have childbirth preparation), pain thresholds were significantly higher during labor (determined up to 8 cm cervical dilatation) than prior to labor and 24 hours postpartum. ⋯ These findings support earlier findings in this laboratory that vaginocervical mechanostimulation elevated pain thresholds in human and animal subjects, and more recent findings that pain thresholds increased in rats during delivery of individual young. The present findings suggest that an endogenous process that attenuates the pain of parturition is activated when the cervix dilates during labor.

Randomized Controlled Trial Clinical Trial
Determinants of pain assessment by nurses.
In this replication study pain assessment and patient perception by nurses was studied in relation to patient characteristics and nurse characteristics. Nurses were randomly assigned to one of 24 descriptions of a hypothetical patient of constant age and unspecified sex. The 24 descriptions varied by duration of pain, presence of a physical pathology, diagnosis category, and depression symptoms. ⋯ Nursing experience seems also to be important in pain assessment. First-year student nurses attributed less pain to the hypothetical patient than third- and fourth-year student nurses and registered nurses. In addition they perceived the patient as more positive when physical pathology was present or when no symptoms of depression were present.
