Yangtze Evening News, February 22 (Correspondent Wang Hui, Wang Yu, Reporter Zhu Dingzhao) Venous access is a life pathway, for critically ill patients, whether intravenous access can be quickly established during the first aid process and timely medication is the key to successful rescue, but for endangered patients in shock, what if the venous access cannot be successfully opened in a short time? Recently, the emergency team of the Second Hospital of Huai'an City used bone marrow infusion technology to open up another life channel for a car accident trauma patient, providing guarantee for the continuous rescue of the injured.
Recently, a patient with cardiorespiratory arrest caused by a car accident trauma was sent to the emergency hall of the Second Hospital of Huai'an City by 120. However, due to the patient's long-term cardiac arrest leading to blood circulation failure, the veins have been severely shriveled, Shi Yan, director of the Department of Emergency and Critical Care Medicine, judged that the success rate of venipuncture of the patient is small, and immediately commanded: "Intrabone marrow infusion!" Subsequently, the first leader Li Dan and the deputy head Feng Lukun led the team to successfully open the intrabone marrow cavity infusion access after some meticulous and skillful operations, providing a guarantee for the continuous rescue of patients.
The emergency team of Huai'an Second Hospital performs bone marrow cavity infusion for the patient.
Shi Yan, director of the Department of Emergency and Critical Care Medicine of the Second Hospital of Huai'an City, introduced that the bone marrow cavity infusion technology, referred to as intraosseous infusion technology, is an emergency infusion technology that quickly establishes intrabone marrow vascular access under special circumstances. Through a special bone marrow puncture trocar, drilled into the bone marrow cavity of the long bone, and then connected to the infusion device, the network of non-collapsing tiny veins in the bone marrow cavity acts like a sponge to quickly absorb the perfused fluid and transport it to the systemic circulation. Bone marrow puncture technology is mainly used to rescue critically ill patients, especially an emergency technology that cannot establish venous access and needs to quickly establish venous access.
Li Dan introduced that when patients have circulatory failure, the intravenous network of the bone marrow cavity still remains in a non-collapsed state and remains connected to the systemic circulation, which can be used as an infusion pathway, and the pharmacokinetics, pharmacodynamics and dosage of the infusion drugs are similar to those of intravenous drugs. Any disease that urgently requires transvascular access for fluids** or drugs** but cannot establish conventional venous access, except for absolute contraindications such as puncture site fractures, puncture site infections, prostheses, and relative contraindications such as osteogenesis imperfecta and severe osteoporosis, can be considered for intrabone marrow infusion technology**.
Compared with peripheral venous access and central venous access, endomyeloid access has the advantages of high success rate, short time-consuming and easy to master, and plays an extremely important role in the emergency rescue of critically ill patients.
