Dexamethasone is effective in decreasing the incidence of shivering. The effectiveness of dexamethasone is independent of temperature and duration of cardiopulmonary bypass. Shivering after cardiac surgery may be part of the febrile response that occurs after release of cytokines during cardiopulmonary bypass.

Flufenamic acid (FA), an inhibitor of the synthesis and action of prostaglandins, was administered to 18 women with preterm labor during the 28th to 36th week of gestation. In 15 patients delivery was postponed, the mean admission/delivery interval being 21.5 days. 2 patients with cervical dilatation of 4 cm delivered within 48 h despite medication. The peripheral plasma levels of 15-keto-13,14-dihydroprostaglandin F_2Α (KH₂ PG_2Α) was high on admission (216 ± 24 pg/ml, mean ± SEM), declined by 50% within 2 h of instituting treatment and remained near the normal level seen in 13 controlled women after the 24th hour.
