摘　　要：目的　探讨不同压力与不同加压方式空气灌肠对小儿难复性肠套叠的整复效果及安全性。方法　回顾性分析780例经空气灌肠整复的肠套叠患儿 ,先中低压复位 ,失败者再行高压整复 ,高压气压范围为 14 .0～ 18.0kPa ,加压方式为遂级式 (每次加压递增 1kPa)或跳跃式加压 (每次加压递增 4～ 8kPa)。结果　中低压整复的 780例中 ,遂级式和跳跃式加压复位成功率分别为 5 1.5 2 %、71.11% ,两者间有非常显著性差异 (P <0 .0 1)。在首轮复位失败的 2 90例中 ,2 81例转用高压整复 ,遂级式和跳跃式加压复位成功率分别为 5 3 .19%、96.15 % ,两者间亦有非常显著性差异 (P <0 .0 1)。两种压力及两种加压方式空气灌肠的肠穿孔率无显著性差异 (P >0 .0 5 )。结论　对于难复性或复杂型小儿肠套叠 ,若无肠坏死Χ线表现 ,可采用高压空气灌肠整复 。Objective To study effectiveness and safety of air enema with different pressure and by different ways of pressurization in reduction of refractory intussusception in children. Methods 780 cases of pediatric intussusception given air enema were retrospectively reviewed. Air enema with medium and low pressure was first given. Air enema with high pressure was given to unsuccessful cases. High pressure ranged from 14.0 to 18.0 kPa. Pressurization adopted cascade methods (with 1 kPa being added each time) or jumping methods (with 4-8 kPa being added each time). Results Among the 780 cases adopted air enema with medium and low pressure, the success rates of cascade pressurization and jumping pressurization were 51.52% and 71.11% respectively. There was obvious difference between the two groups ( P <0.01). For the 290 cases failing first round of reduction operation, 281 cases adopted high-pressure restoration. The success rates of cascade pressurization and jumping pressurization were 53.19% and 96.15% respectively. There also existed obvious difference between the two groups ( P <0.01). There was no obvious difference between perforation rate of air enema with two kinds of pressure and the two methods of pressurization ( P >0.05). Conclusion For refractory or complicated intussusception, high-pressure restoration may be adopted in case there is no X-ray indication of bowel necrosis. Jumping pressurization may achieve better restoration effects than cascade pressurization.
