Percutaneous needle tracheostomy and transtracheal ventilation continues to be advocated for the management of upper airway obstruction. Recent studies recommend the use of artificial ventilation. However, as apparatus for this is not always available and because there remains some doubt regarding conditions for successful use of needle tracheostomy during spontaneous respiration, we undertook such a study in dogs. Pressure-flow characteristics of short hollow needles 18-10 SWG were first determined. The smallest of these (14 SWG Bardic Intracath) that would deliver flow sufficient (by calculation) to meet the respiratory requirement of 10-13 kg laboratory dogs was selected for further study. Respiration was possible by spontaneous or artificial methods in the presence of complete tracheal occlusion. Little or no deterioration was noted in an hour of such breathing. Artificial ventilation by machine and by hand could considerably lower PaCO2. We conclude that the technique is possible provided appropriate needles are selected and care is given to their method of use.
经皮穿刺针气管切开术和经气管通气仍被提倡用于上气道梗阻的处理。近期研究推荐使用人工通气。然而，由于进行人工通气的设备并非总是可用，且对于在自主呼吸期间成功实施针气管切开术的条件仍存在一些疑问，我们在犬类身上开展了这样一项研究。首先测定了18 - 10号规格短空心针的压力 - 流量特性。从中选择了能够（通过计算）输送足够流量以满足10 - 13千克实验犬呼吸需求的最小规格针（14号巴德体内穿刺针）进行进一步研究。在气管完全阻塞的情况下，通过自主或人工方法均可实现呼吸。在这样呼吸一小时的过程中，未观察到明显恶化或仅有轻微恶化。通过机器和手动进行人工通气可显著降低动脉血二氧化碳分压（PaCO2）。我们得出结论，只要选择合适的针并注意其使用方法，该技术是可行的。
