Efficacy and safety of tranexamic acid administration for subarachnoid hemorrhage: a systematic review and meta-analysis.

ABSTRACT:

Introduction

Aneurysmal subarachnoid hemorrhage (SAH) carries a high risk of early rebleeding and worsens prognosis. Tranexamic acid (TXA), an antifibrinolytic agent, can prevent rebleeding; however, its effects on mortality and neurological outcomes remain controversial.

Methods

This review evaluated the efficacy and safety of TXA with SAH. MEDLINE, CENTRAL, EMBASE, ICTRP, and ClinicalTrials.gov were systematically searched for randomized controlled trials (RCTs) and non-randomized studies of interventions (NRSIs) to assess TXA use in SAH. Studies comparing TXA with controls with SAH were included. The primary outcome was the mortality; secondary outcomes included neurological outcomes, rebleeding, thromboembolism, delayed cerebral ischemia (DCI), hydrocephalus, and adverse
