Indomethacin and the stress response to hysterectomy.

The influence of indomethacin on the surgical stress response was evaluated in a double-blind study of 20 patients, scheduled for abdominal hysterectomy. The patients were randomly allocated to treatment with either indomethacin, 0.8 mg/kg i.v. preoperatively followed by 100 mg rectally 8-hourly for 3 days (Group I), or placebo (Group P), in both cases supplemented with nicomorphine as needed. Thiopentone was used for induction of anaesthesia, followed by nitrous oxide, enflurane, suxamethonium, and pancuronium. In both groups a significant increase in blood glucose and serum cortisol was seen postoperatively. Twenty-four hours later the values had almost returned to baseline. No differences were found between the absolute increases in the two groups. In both groups the serum concentrations of C-reactive protein, haptoglobin, and orosomucoid increased after an initial small decrease. We conclude that pathways involving prostaglandin synthesis play only a minor role in eliciting the postoperative hyperglycaemic, hypercortisolaemic, and acute phase protein response.
