Fifty patients with non-cirrhotic portal fibrosis who were admitted to hospital because of upper gastrointestinal bleeding were randomly assigned to treatment with either oral propranolol given in doses that reduced the resting pulse rate by 25% (25 patients) or with a placebo (25 patients). One year after the start of the study 20 patients in the propranolol group and five patients in the placebo group were free from recurrent gastrointestinal bleeding (p less than 0.0001). Giving continuous oral propranolol treatment is therefore effective in preventing recurrent upper gastrointestinal bleeding in patients with non-cirrhotic portal fibrosis.
50例因上消化道出血入院的非肝硬化性门脉纤维化患者被随机分为两组,一组口服普萘洛尔,剂量以使静息心率降低25%为准(25例患者),另一组服用安慰剂(25例患者)。研究开始一年后,普萘洛尔组有20例患者、安慰剂组有5例患者未再发生胃肠道出血(P<0.0001)。因此,持续口服普萘洛尔治疗对预防非肝硬化性门脉纤维化患者上消化道出血复发有效。
