ObjectiveTo investigate the effect of acute non-isovolemic hemodilution (ANIH) on spinal surgery. MethodsFrom January 2012 to July 2013, 80 patients scheduled for spinal surgery were enrolled. The patients were randomized into four groups, with 20 in each group. Patients in group A were infused with Ringer's injection and polygeline for fluid loss, physiological needs and blood loss. In group B, the patients were infused with acute hypervolemic hemodilution. In group C, patients were infused with acute nomovolemic hemodilution. In group D, patients were infused with ANIH. The hemodynamics and arterial blood gas indexes were detected in all the patients. ResultsThe mean blood pressure in group A and C was significantly more stable than that in group B and D. The central vein pressure in group B and D was significantly higher than that in group A and C after hemodilution (P<0.05), while the hematocrit in group B and D was significantly lower than that in group A and C (P<0.05). Allogeneic blood transfusion was performed in group A and B, while it was not performed in group C and D. ConclusionANIH can reduce the volume of blood loss during spinal surgery, and it is safe.
ObjectiveTo explore the effect of level management model in the application of nursing for pressure ulcers after spinal surgery. MethodA total of 3 558 patients underwent spinal surgeries between January 2014 and September 2015 were selected. We established a level management model, confirmed the personnel responsibilities, strengthened the pressure ulcers risk assessment of new inpatients, and standardized the processes of reporting pressure sores. We carried out the level management model between January and June 2014, summarized experience and formed a system file between July and December 2014, applied to the clinical work after continuous improvement between January and September 2015. High risk of pressure ulcers reporting rate, incidence of high-risk pressure ulcers, and healing rate of pressure ulcers were compared at the various stages. ResultsThe reporting rate of pressure ulcers raised, the incidence of pressure ulcers increased and the curing rate decreased after continuous improvement (P<0.05). ConclusionsLevel management model may effectively improve the quality of the nursing for spinal pressure ulcers.
Objective To evaluate the current status of classification and repair methods for dural injury caused by spinal surgery or trauma, providing new strategies and ideas for the clinical repair of dural injury and the development of related materials. MethodsThe literature related to dural injury both at home and abroad in recent years was thoroughly reviewed and analyzed in order to draw meaningful conclusions. ResultsThere have been numerous retrospective studies on dural injury, but there is a scarcity of prospective and multi-center studies, resulting in a low level of evidence-based research. The incidence and risk factors of dural injury have primarily been studied in relation to common degenerative spinal diseases of the cervical and lumbar spine, with insufficient research on thoracic spine-related diseases. Currently, a universally recognized method for grading and classifying dural injury has not been established, which hampers the development of clinical guidelines for their repair. Furthermore, although there are repair materials and surgical strategies available to address clinical issues such as suture leakage and surgical repair of dural injury in complex locations, there is a lack of comprehensive clinical research and evidence-based data to validate their scientificity and reliability. ConclusionRegardless of the classification of dural injury, suture remains the most important repair method. It is important to further develop new patches or sealants that can meet clinical needs and reduce the difficulty of repair.
