Efficacy and safety of phenobarbital for benign convulsions with mild gastroenteritis: A prospective randomized...

previous studies have shown that phenobarbital (PB) is a effective and safe drug in the treatment of benign convulsions with mild gastroenteritis (CwG), but there is a lack of large sample prospective randomized controlled study of different doses. This study was a prospective randomized controlled study on the efficacy and safety of different doses of phenobarbital for CwG. There has been no similar study.

One hundred twenty CwG cases were included in this study. All of them were hospitalized in the Department of Neurology of Jiangxi Provincial Children's Hospital from January 2019 to August 2021. They were randomly divided into 10 mg/kg single dose group (Group A, n = 60) and 5 mg/kg single dose group (Group B, n = 60). The criteria for judging the efficacy of PB in our study were there was no convulsion in the course of acute gastroenteritis within 2 weeks after using PB.

The effective rate was 93.33% in group A and 80.00% in group B. There was significant difference between the 2 groups (P < .05). Drowsiness was the most frequent adverse reaction. 14 cases in group A and 7 cases in group B had drowsiness. There was no significant difference between the 2 groups in the incidence of adverse events such as somnolence, ataxia, abnormal liver function, anemia, abnormal leukocyte, respiratory depression, cognitive impairment, rash, abnormal platelet and abnormal renal function (P > .05). All side reaction were transient.

it is suggested that PB 10 mg/kg intravenously should be used as soon as possible for CwG, which has high effectiveness and safety.
