Safety Operation Specifications And Clinical Precautions Of Intraosseous Needles

As a professional invasive medical puncture instrument, intraosseous needles have strict safety operation specifications in clinical application. Standardized operation is not only the key to ensure the success of infusion, but also the core guarantee to avoid medical complications such as bone injury, nerve damage, infection and extravasation. All operators need to master the matching rules of different specifications of needles and applicable crowds, and standardize the puncture position, depth and operation process according to clinical guidelines.

In the selection of needle specifications, medical staff must match the needle body length according to the patient's age, weight and body type. For pediatric patients under 40kg, only 1.5cm 15G intraosseous needles can be used. Excessively long needle bodies are easy to penetrate the tibia, damage the deep nerve and vascular tissues, and cause secondary trauma. For children over 40kg and non-obese adults, 2.5cm conventional needles are the preferred choice, which can accurately reach the bone marrow cavity with moderate depth and minimal tissue damage.

For obese adult patients, the operation needs to be judged according to the actual physical condition. When the patient's tibial tuberosity is clearly palpable and the subcutaneous fat is thin, the 2.5cm conventional needle can be used for proximal tibial intraosseous infusion; when the patient is severely obese, the tibial tuberosity is not obvious, and the fat layer is thick, the 4.5cm long needle must be used to ensure that the needle body penetrates the fat layer and cortical bone and stably enters the bone marrow cavity, avoiding infusion failure caused by insufficient puncture depth.

In terms of operation safety, the stainless steel needle body has high structural stability, which can effectively avoid bending and fracture during puncture. Before use, it is necessary to check the sterility and integrity of the product packaging to ensure that the product is not contaminated. After puncture, fix the needle body stably to avoid displacement and falling off during infusion. After the end of rescue treatment, take out the needle body in a standardized manner and do a good job of wound disinfection to reduce the risk of clinical infection. Standardized operation and accurate specification matching make intraosseous needles maintain high safety and stability in clinical emergency application.
