Assessment of appropriateness for each patient to take part in the study will be performed approximately 2 hours following delivery. Those patients who consent to participate in the trial will be allocated to treatment groups in a double-blinded, randomized manner. Women in the study group will receive treatment with pads soaked in a cold aqueous solution of magnesium sulfate at 33% (w/v) concentration, while those in the control group will receive treatment with pads soaked in cold water.
