[ { "id": 0, "entity": "胃肠道", "start_offset": 53, "end_offset": 56, "label": "bod" }, { "id": 1, "entity": "中毒", "start_offset": 71, "end_offset": 73, "label": "dis" } ]
目前,国内外大多数提倡采用此悬液进行洗胃。

有些化合物(如巴比妥酸盐、水杨酸盐及异烟肼等)在碱性环境下离子化程度增加,处理时如在补液中适当补给碳酸氢钠以碱化尿液,可减少其在肾小管内重吸收,提高排出率。
[ { "id": 0, "entity": "尿液", "start_offset": 56, "end_offset": 58, "label": "bod" }, { "id": 1, "entity": "肾小管", "start_offset": 64, "end_offset": 67, "label": "bod" } ]

[ { "id": 0, "entity": "透析治疗", "start_offset": 10, "end_offset": 14, "label": "pro" }, { "id": 1, "entity": "中毒", "start_offset": 18, "end_offset": 20, "label": "dis" }, { "id": 2, "entity": "血液", "start_offset": 56, "end_offset": 58, "label": "bod" }, { "id": 3, "entity": "透析", "start_offset": 74, "end_offset": 76, "label": "pro" } ]

[ { "id": 0, "entity": "左冠状动脉异常", "start_offset": 3, "end_offset": 10, "label": "dis" }, { "id": 1, "entity": "畸形左冠状动脉", "start_offset": 10, "end_offset": 17, "label": "dis" }, { "id": 2, "entity": "肺动脉", "start_offset": 20, "end_offset": 23, "label": "bod" }, { "id": 3, "entity": "右冠状动脉", "start_offset": 24, "end_offset": 29, "label": "bod" } ]
在胎儿期,由于肺动脉与主动脉的压力和氧饱和度相似,心肌的灌注与氧合正常。
[ { "id": 0, "entity": "肺动脉", "start_offset": 7, "end_offset": 10, "label": "bod" }, { "id": 1, "entity": "主动脉", "start_offset": 11, "end_offset": 14, "label": "bod" }, { "id": 2, "entity": "心肌", "start_offset": 25, "end_offset": 27, "label": "bod" } ]
然而,出生后,随着肺动脉压力的降低,血液可自右冠状动脉经侧支进入左冠状动脉,最终进入肺动脉。
[ { "id": 0, "entity": "肺动脉", "start_offset": 9, "end_offset": 12, "label": "bod" }, { "id": 1, "entity": "右冠状动脉", "start_offset": 22, "end_offset": 27, "label": "bod" }, { "id": 2, "entity": "左冠状动脉", "start_offset": 32, "end_offset": 37, "label": "bod" }, { "id": 3, "entity": "肺动脉", "start_offset": 42, "end_offset": 45, "label": "bod" } ]
这样就产生了少量的左向右分流,应该供应心肌的血液通过这些通道进入了肺动脉。
