Although rare, the misplacement of nasogastric tubes into the pleural space has been described. The prognosis of such injuries is improved by prompt recognition; therefore, it is important for physicians who practice nasogastric intubation to be aware of this potential complication, and to be familiar with an approach to early diagnosis.
We present a case of perforation of the cervical oesophagus by a polyvinylchloride nasogastric tube, following a traumatic attempt at nasotracheal intubation. This resulted in passage of the nasogastric tube into the pleural space.
Our experience with this case and a review of the relevant literature suggest that such trauma may predispose to malplacement of nasogastric tubes. Clinical signs, such as aspiration of fluid from a nasogastric tube, and auscultation of air insufflated into the stomach, are unreliable; however, the presence of subcutaneous air in the neck on chest radiograph, and the presence of cervical crepitance on physical examination, are valuable signs in the early diagnosis of perforation of the cervical oesophagus. Contrast oesophagography remains the diagnostic manoeuvre of choice in confirming the diagnosis, but early diagnosis will depend on a high index of suspicion and prompt viewing of chest x-rays. The management and the prognosis of such injuries depends on the level of the perforation, delays in diagnosis, and the presence of associated mediastinitis.
尽管罕见,但已有人描述过鼻胃管误置入胸膜腔的情况。及时识别可改善此类损伤的预后;因此,实施鼻胃管插管的医生了解这一潜在并发症并熟悉早期诊断方法很重要。
我们报告一例在尝试经鼻气管插管时发生创伤后,聚氯乙烯鼻胃管导致颈段食管穿孔的病例。这致使鼻胃管进入胸膜腔。
我们对该病例的经验及相关文献回顾表明,此类创伤可能易导致鼻胃管误置。从鼻胃管吸出液体及听诊向胃内注入的空气等临床体征并不可靠;然而,胸部X线片显示颈部皮下气肿以及体格检查发现颈部有捻发音是颈段食管穿孔早期诊断的重要体征。食管造影仍是确诊的首选诊断方法,但早期诊断取决于高度的怀疑指数和及时查看胸部X线片。此类损伤的处理及预后取决于穿孔的部位、诊断延误情况以及是否存在相关纵隔炎。
