目的:测定小儿急性骨髓炎早期病灶骨内压变化,探索其在早期诊断和治疗中的应用价值。方法:对18例早期小儿急性骨髓炎进行了病灶骨内压和健侧骨内压的对照测定。结果:18例病灶骨内压均显著升高(5.5±0.9kPa,1cmH_2O=0.098kPa),与对照侧骨内压(2.6±0.5kPa)相比,差异有非常显著意义(P<0.01)。结论:急性骨髓炎早期病灶骨内压显著升高。骨内压测定有助于该病的早期诊断,术中骨内压的动态监测可作为判断减压钻孔是否准确有效的客观标准,对保证手术效果有重要的价值。
Objective: To determine the change of intraosseous pressure in early stage of acute osteomyelitis in children, and to explore its value in early diagnosis and treatment. Methods: 18 cases of early childhood acute osteomyelitis were examined by intra-articular pressure and contralateral bone pressure. Results: The bone pressures in all 18 cases were significantly increased (5.5 ± 0.9kPa, 1cmH_2O = 0.098kPa) compared with the control group (2.6 ± 0.5kPa). The difference was significant (P <0.01). Conclusion: The early intraosseous pressure of acute osteomyelitis is significantly increased. The determination of intraosseous pressure is helpful for the early diagnosis of the disease. The dynamic monitoring of intraosseous pressure during surgery can be used as an objective criterion to judge whether the decompression drilling is accurate and effective, which is of great value to ensure the surgical effect.
