Long before the invention of electric drills and anesthesia early humans drilled teeth to treat decay, according to research published Wednesday. 科学家日前公布的一项研究结果显示,早在电钻和麻醉剂发明之前,早期人类就开始通过在牙齿上钻孔的方法来医治蛀牙。
Conclusion: Combined acupoint electric stimulation and general anesthesia could maintain the tissue oxygen supply and demand balance better in the isoflurane induced hypotension process. 结论:穴位电刺激配合全麻行异氟醚控制性降压能更好地维持组织氧供需平衡。
