Objective To explore the differences of bacterial culture results and time consumption between the two methods of holding the syringes to draw physic liquors,so as to find the objective and scientific evidences to raise the efficiency of the clinical nursing work and to ensure the medication safety at the same time. Methods Making bacterial cultures for the physic liquors respectively drawn by grasping the piston of syringes (30 cases in the experimental group) and grasping the piston holder of syringes(30cases in the control group).Recorded the time consumption by grasping the piston of syringes to draw the physic liquors (the experimental group) and grasping the piston holder of syringes to draw the physic liquors (the control group).The testing results were compared between the two groups. Results Bacterial cultures:There was no bacteria growth in both groups.Timing:The time spent by grasping the piston of syringes to draw physic liquors was obviously shorter than that by grasping the piston holder of syninges to draw physic liquors. Conclusions Grasping the piston of syringes to draw physic liquors can ensure the medication safety and raise the work efficiency.

OBJECTIVE: To evaluate the application of surgical strategies for the treatment of cervical ossification of the posterior longitudinal ligament (OPLL) involving the C ₂ segment. METHODS: The literature about the surgery for cervical OPLL involving C ₂ segment was reviewed, and the indications, advantages, and disadvantages of surgery were summarized. RESULTS: For cervical OPLL involving the C ₂ segments, laminectomy is suitable for patients with OPLL involving multiple segments, often combined with screw fixation, and has the advantages of adequate decompression and restoration of cervical curvature, with the disadvantages of loss of cervical fixed segmental mobility. Canal-expansive laminoplasty is suitable for patients with positive K-line and has the advantages of simple operation and preservation of cervical segmental mobility, and the disadvantages include progression of ossification, axial symptoms, and fracture of the portal axis. Dome-like laminoplasty is suitable for patients without kyphosis/cervical instability and with negative R-line, and can reduce the occurrence of axial symptoms, with the disadvantage of limited decompression. The Shelter technique is suitable for patients with single/double segments and canal encroachment >50% and allows for direct decompression, but is technically demanding and involves risk of dural tear and nerve injury. Double-dome laminoplasty is suitable for patients without kyphosis/cervical instability. Its advantages are the reduction of damage to the cervical semispinal muscles and attachment points and maintenance of cervical curvature, but there is progress in postoperative ossification. CONCLUSION OPLL involving the C ₂ segment is a complex subtype of cervical OPLL, which is mainly treated through posterior surgery. However, the degree of spinal cord floatation is limited, and with the progress of ossification, the long-term effectiveness is poor. More research is needed to address the etiology of OPLL and to establish a systematic treatment strategy for cervical OPLL involving the C ₂ segment.
