The paramedian as opposed to midlineneedle approach and smaller epidural needle or catheter gaugesdo not reduce the risk of epidural vein cannulation.

以下两种策略未能降低误置入硬膜外静脉的风险：旁正中进针穿刺法相比中线进针法和采用较小号硬膜外穿刺针或导管。

One esophageal intubation was readily recognized by visualizationof the tube in the left paratracheal space.

From the base to the crown in axial, the vessel-elements proportion increases in fluctuation, contrary to the ray proportion. The fiber proportions in the regions of base and crown are less than that in the trunk of tree, and fluctuate at 65% or so. The parenchym proportion increases quickly to the 1.3m height of tree, reaching the maximum at 9.52%, and then decreases quickly to the 3.3m height of tree (8.90%); afterward it leveled off and increases slightly.

组织比量轴向变异表现为随树高增加导管比量波动性递增，与木射线比量相反；纤维比量在近根区和近冠区稍小，而主干部稍大，并在65%左右波动；轴向薄壁细胞比量先随树高增加急剧增加，到1.3m树高处达最大值（9.52%）后又急剧降低至3.3m树高处的8.90%，以后基本稳定并在波动中略有增加。
