ABSTRACT
Objective To explore the method and management of pre-hospital care and raise the level of traffic injuries in pre-hospital care by summarizing the clinical features of death patients with severe tragic accident trauma Methods The basic data of 62 death patients with severe traffic accident trauma was analyzed according to death report statistics of severe traffic accident trauma from January 1st,2005 to December 31th,2008 Results Brain injury death accounted for most of traffic accident trauma death.The mortality rate of brain injury in the wounded wag 8.28%(13/157),but of asphyxia and hemorrhagic shock was 2.55%(4/157),3.18%(5/157)respectively in 2005.With the development of treatment and rescued in time, the mortality rate reduced to 6.11%(11/180),0,0.56%(1/180)in 2008.Conclesions It should be trying to shorten the time of pre-hospital care for pafients with trsffic accident trauma,especially in patients combined with hemorrhagic shock,asphyxia,severe brain injury.It is concluded that rapid and effective pre-hospital care can significantly reduce death rate and self-help or each other rescue training would also be effective to reduce mortality.
ABSTRACT
Objective For decreasing the infected rate,the prevention and cure methods of intracranial infections following posterior fossa craniotomy were study. Methods Twenty-eight patients with the intracranial infections following posterior fossa craniotomy were examined by lumbar puncture,and analyzed cerebrospinal fluid with routine examination and reference to the bacteriological data and drug sensitive tests. All the patients were treated with high dosage sensitive antibiotics, and draining continually the infected cerebrospinal fluid by lumbar puncture catheterization and injected small dosages of antibiotics into intraspinal for most cases. Results Twenty-eight patients had intracranial hypertension by lumbar puncture examination, outcome of cerebrospinal fluid culture indicated that 17 cases had bacteria growth and 11 cases had no bacteria. The intracranial infection was controlled effectively,and 96.4%(27 cases) were cured, 1 case dead of systemic failure. Conclusions Strict aseptic techniques,reduce operative time,decrease intracranial place of foreign matters, such as gelfoam, hemostatic gauze and artificial implants, could reduce the possibilities of intracranial infections. Appropriate antibiotics selection,lumbar puncture catheterization and intraspinal administration of antibiotics can cure intracranial infections effectively.
ABSTRACT
AIM: To study the survival, transfer and distribution of bone marrow CD34+/CD45+ cells from transgenic GFP mouse after transplanted into the completed transversional spinal cord rat model. METHODS: The bone marrow cells isolated from transgenic GFP mice were cultured in vitro. The cultured cells were identified by anti-CD34 and anti-CD45 monoclonal antibodies, and were transferred into the end of transection spinal cord. Paraformaldehyde was infused into the left ventricle of the rat model at the 24 h, 48 h, 1 week, 2 weeks, 4 weeks and 8 weeks after cell transplantation. Through sank and frozen, the spinal cord was sectioned at 10 ?m thickness. The green fluorescence positive cells were observed under the fluorescence microscope. CD34+/CD45+ cells were identified by immunohistochemistry staining. RESULTS: Green fluorescence positive cells were found at the head and the end of the completed transection part of spinal cord. Most of the green fluorescence positive cells were distributed in the gray substance of spinal cord. CD34+/CD45+ cells were found by immunohistochemistry staining. CONCLUSION: CD34+/CD45+ cells survived in spinal cord of SD rat, and migrated to the head of the transection part. The distance of migration was extended by the time.
