In a 10-year period, 22 neonates with esophageal atresia (EA) and tracheoesophageal fistula (TEF) required high pressure ventilatory support soon after birth because of respiratory distress syndrome (RDS). Eleven of the 22 or 50% survived overall, but if the 5 patients who died before definitive surgical repair could be attempted are excluded, 11 of 17 or 65% survived. More importantly, 4 of 7 (57%) patients who had gastrostomy performed first survived while 7 of 10 (70%) who had fistula ligation performed first survived. The difficulties with intraoperative management of those who had gastrostomy performed first were even more impressive. Our experience leads us to conclude that patients with EA and TEF with severe RDS who require high pressure ventilation preoperatively represent a group of patients who require special consideration. The danger to such patients with increased pulmonary resistance is not gastric distention but sudden loss of intragastric pressure. In the presence of poor lung compliance, the upper gastrointestinal tract functions in continuity with the tracheobronchial tree. A sudden loss of intragastric pressure, as with placement of a gastrostomy tube, results in an acute loss of effective ventilating pressure. Resuscitation of such a patient is not possible until leakage from the esophagus is controlled by ligation of the fistula or transabdominal occlusion of the distal esophagus. Placement of a Fogarty catheter into the fistula via a bronchoscope is effective but may not be feasible in every case. Early thoracotomy and ligation of the fistula in patients with progressive RDS provides immediate improvement in ventilatory efficiency and relief of gastric distention.
在10年期间,22例患有食管闭锁(EA)和气管食管瘘(TEF)的新生儿因呼吸窘迫综合征(RDS)在出生后不久就需要高压通气支持。22例中的11例(50%)总体存活,但如果排除在尝试进行确定性手术修复前死亡的5例患者,17例中的11例(65%)存活。更重要的是,先进行胃造口术的7例患者中有4例(57%)存活,而先进行瘘管结扎术的10例患者中有7例(70%)存活。先进行胃造口术的患者术中管理的困难更加明显。我们的经验使我们得出结论,患有EA和TEF且术前需要高压通气的严重RDS患者是需要特殊考虑的一组患者。此类肺阻力增加患者的危险不是胃扩张,而是胃内压力突然丧失。在肺顺应性差的情况下,上消化道与气管支气管树连续起作用。胃内压力突然丧失,如放置胃造口管时,会导致有效通气压力急剧丧失。在通过瘘管结扎或经腹闭塞远端食管控制食管漏之前,无法对此类患者进行复苏。通过支气管镜将Fogarty导管置入瘘管是有效的,但并非在每种情况下都可行。对于进行性RDS患者,早期开胸并结扎瘘管可立即提高通气效率并缓解胃扩张。
