OBSERVATIONAL
Conditions
Summary
This single-center, prospective observational study will enroll 52 critically hematology patients aged 18-65 years including agranulocytosis, thrombocytopenia, severe anemia, advanced tumors, septic shock, sepsis DIC、 severe gastrointestinal bleeding, involvement of the central nervous system or intracranial hemorrhage, patients undergoing hematopoietic stem cell transplantation，etc. Vascular access will be established via intraosseous (IO) needle placement, primarily to evaluate first-attempt puncture success rate, therapeutic efficacy, and overall survival rate. Secondary endpoints include infusion speed, hemodynamic improvement, and procedural complications such as local infection and fat embolism. The study aims to definitively assess the efficacy and safety of IO infusion as a rapidly established, "non-collapsible" alternative vascular access route in the hematologic intensive care setting.
Eligibility
Inclusion Criteria1
- \. Age: 18 to 65 years old. 2. Critically patients with hematologic diseases, including:① Highly suspected or diagnosed patients with rapidly progressing highly lethal hematological diseases;② Patients with hematological disorders complicated by severe complications, including agranulocytosis, thrombocytopenia, severe anemia, advanced tumors,septic shock, sepsis, DIC、 severe gastrointestinal bleeding, involvement of the central nervous system or intracranial hemorrhage, etc;③ Patients with hematological diseases combined with important organ dysfunction, including respiratory failure, heart failure, renal failure, liver failure, etc;④ Patients undergoing hematopoietic stem cell transplantation or those experiencing serious complications in new immunotherapy, such as hyperacute graft-versus-host disease (GVHD), grade 3-4 cytokine release syndrome (CRS) or immune effector cell associated neurotoxicity syndrome (ICANS), grade 3-4 immune checkpoint inhibitor associated interstitial lung disease, etc;⑤ Other critically patients who require life support and 24-hour monitoring.
Exclusion Criteria3
- \. Fracture at the intended puncture site (due to the risk of fluid extravasation into subcutaneous tissues).
- \. Extensive soft tissue injury at the intended puncture site, resulting in insufficient anatomical landmarks for safe puncture.
- \. Local infection in the intended puncture area. 4. History of major orthopedic surgery in the intended puncture region. 5. Presence of a local prosthetic implant. 6. A site previously used for intraosseous (IO) access within the last 24 hours (to avoid re-puncture).

Interventions
The interventional approach employed in this study is intraosseous (IO) infusion. This technique involves the percutaneous insertion of a specialized intraosseous needle or a powered driver device into the medullary cavity of a long bone (e.g., proximal tibia or humerus) to establish rapid vascular access for the administration of fluids, medications, and blood products. Its core principle leverages the bone marrow space as a "non-collapsible venous sinus," providing a rapid and effective life-saving channel for critically ill hematology patients-such as those with concomitant shock, severe hemorrhage, or multiple organ dysfunction-in whom conventional vascular access is challenging due to critical illness or underlying coagulopathies.
