- Brief Summary
Primary pontine hemorrhage (PPH) is not common but is the most catastrophic subtype of intracerebral hemorrhage, with acute mortality between 30% and 60%. For severe PPH, defined as Glasgow Coma score (GCS) \<8 and hematoma volume≥5ml, the mortality rate is as high as 80-100%. Guidelines from the American Heart Association and European Stroke Organization do not make definite specifications. More than a century after Finkelnburg first explored the brainstem for hematoma, however, plenty of researches have shown surgery can save lives and improve the prognosis for selective patients and can be an effective and safe treatment. This study is proposed to validate the safety of surgical treatment in severe primary pontine hemorrhage.
- Detailed Description
The study is being conducted from Jan 2022 to Nov 2024 in 20 neurosurgical units. This STIPE trial is an investigator-initiated, parallel (3:1 to surgical HE or MT), multi-centre, randomized controlled open-label trial following the Consolidated Standards of Reporting Trials (CONSORT) guidelines and will be conducted from Jan 2022 to Nov 2024 in 20 Tertiary hospitals in China. The flow chart of the clinical trial is presented in Figure 1. Neurosurgeons involved in the study are senior investigators with good clinical experience in sPPH management. Moreover, all investigators are well trained centrally according to the requirements.

Name Time Method Safety Outcome Number 3: Rate of Symptomatic Rebleeding 72 hours post surgery The difference in the rate of symptomatic rebleeding 72 hours post surgery.
Safety Outcome Number 1: Rate of Mortality 30 days from randomization Percentage of participants who died during the first 30 days after randomization.
Safety Outcome Number 2: Rate of Cerebritis, Meningitis, Bacterial Ventriculitis 30 days from randomization Percentage of participants who had a bacterial brain infection (cerebritis, meningitis, ventriculitis) within 30 days of randomization.
- Secondary Outcome Measures
Name Time Method neurological functional status of 30 days, 90 days, 180 days, and 365 days measured by Modified Rankin Scale (mRS), GCS and GOS. 30 days, 90 days, 180 days, and 365 days after surgery neurological functional status of 30 days, 90 days, 180 days, and 365 days measured by Modified Rankin Scale (mRS), GCS and GOS.

The 5-level EuroQol five dimensions questionnaire (EQ-5D) version (EQ-5D-5L) at 180 days and 365 days 180 days and 365 days after surgery The EQ-5D-5L essentially consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The former descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. The latter is numbered from 0 to 100. 100 means the best health you can imagine. 0 means the worst health you can imagine.
