A grand mal convulsion occurred in a patient with decompensated cor pulmonale. Although only modest doses of oral theophylline were being administered at the time of the convulsion the serum theophylline level was markedly raised and the theophylline clearance was very low. After treatment for cor pulmonale theophylline clearance improved; however, with the subsequent onset of fever and pneumonia the clearance decreased again, illustrating the potential lability of theophylline clearance.
一名肺心病失代偿期患者发生了癫痫大发作。尽管在发作时仅给予了适量的口服茶碱,但血清茶碱水平显著升高,且茶碱清除率非常低。在治疗肺心病后,茶碱清除率有所改善;然而,随后发热和肺炎发作时,清除率再次下降,这说明了茶碱清除率可能具有不稳定性。
