Thermic effects of tocolytic agents: decreased temperature with magnesium sulfate.
The effect of the tocolytic agents terbutaline and magnesium sulfate on patients' temperatures was examined. Fifty-two women admitted for preterm labor were randomized to a treatment protocol for one of the two agents. Oral temperatures were measured initially and every two hours during treatment. There was no significant difference between the initial temperature and the lowest temperature recorded during treatment in the terbutaline group, but temperature decreased significantly during treatment with magnesium sulfate. This decrease in maternal temperature may have importance in the treatment of preterm labor with magnesium sulfate in patients with an infectious etiology for uterine activity.
