To date, common therapy in patients with intracranial hemorrhage (ICH) includes prophylaxis of seizure using antiepileptic drugs, commonly phenytoin. Phenytoin therapy is associated with a high incidence of cognitive disturbance. Levetiracetam is known to cause less cognitive disruption and may be a suitable alternative for seizure prophylaxis. Cognitive outcomes in ICH patients receiving seizure prophylaxis with levetiracetam or phenytoin are compared.
A retrospective chart review was conducted with 269 patients who received prophylactic levetiracetam or phenytoin between August 2005 and May 2008. A total of 85 reviewed patients met inclusion criteria (phenytoin n = 25, levetiracetam n = 60).
Statistically significant results included higher Glasgow Coma Scores (GCS) at dismissal (median, 14 vs. 11, P = 0.023), lower seizure incidence (0.0 vs. 8%, P = 0.03) for patients receiving levetiracetam than those treated with phenytoin and patients being discharged home (21.7% vs. 16%, P = 0.03). Observed trends included greater cognitive function retention rate (56.7% vs. 36%, P = 0.08).
Despite similarities in hemorrhage type and severity at onset, patients receiving levetiracetam had better cognition at discharge and fewer seizures than patients receiving phenytoin. These data suggest that levetiracetam is more effective than phenytoin for seizure prophylaxis without suppression of cognitive abilities in patients with ICH.
迄今为止,颅内出血(ICH)患者的常见治疗方法包括使用抗癫痫药物(通常是苯妥英钠)预防癫痫发作。苯妥英钠治疗与认知障碍的发生率高有关。左乙拉西坦已知引起认知障碍的发生率较低,可能是预防癫痫发作的合适替代品。比较了接受左乙拉西坦或苯妥英钠预防癫痫发作的 ICH 患者的认知结果。
对 2005 年 8 月至 2008 年 5 月期间接受预防性左乙拉西坦或苯妥英钠治疗的 269 例患者进行了回顾性图表审查。共有 85 例符合纳入标准的患者接受了审查(苯妥英钠组 n = 25,左乙拉西坦组 n = 60)。
统计学上显著的结果包括:左乙拉西坦组出院时格拉斯哥昏迷评分(GCS)更高(中位数,14 对 11,P = 0.023),癫痫发作发生率更低(0.0 对 8%,P = 0.03),与接受苯妥英钠治疗的患者相比,出院回家的患者(21.7%对 16%,P = 0.03)。观察到的趋势包括更高的认知功能保留率(56.7%对 36%,P = 0.08)。
尽管在出血类型和发病时的严重程度上存在相似性,但接受左乙拉西坦治疗的患者在出院时的认知功能更好,癫痫发作更少,而接受苯妥英钠治疗的患者则更少。这些数据表明,左乙拉西坦在不抑制 ICH 患者认知能力的情况下,比苯妥英钠更有效地预防癫痫发作。
