NTRODUCTION
Continuous ambulatory peritoneal dialysis (持续性非卧床腹膜透析CAPD) is used to treat endstage renal failure in an increasing number of patients.
CAPD has an advantage over hemodialysis in that it allows patients greater freedom to perform daily activities; it also provides other clinical benefits. However, the long-term effectiveness of CAPD is limited plications, which have various causes.
INDICATIONS AND TECHNIQUE
适应症:复发性腹膜炎,透析液交换困难,腹壁或***软组织水肿,腹壁局限性膨出,超滤减少
方法:在CT腹膜造影前,腹腔的透析液要完全引流;1ml/kg非离子型造影剂+ 30ml/kg透析液混匀,缓慢输入腹腔,要求严格无菌操作;患者行走、翻身等活动30分钟后CT扫描;检查完毕将含有造影剂的腹透液置换出来
NORMAL FINDINGS
Limited dispersion due to adhesions
ABNORMAL FINDINGS
Peritonitis:
Bacterial peritonitis is the plication of CAPD.
Patients undergoing CAPD are more susceptible to tuberculous peritonitis than those with normal renal function or those undergoing hemodialysis, partly because of their decreased cellular immunity.
Infected fluid collections.
Tuberculous peritonitis
Catheter-plications
Catheter Malposition.—The distal catheter tip should be inserted in a dependent position into the rectovesical pouch (in male patients) or the rectouterine pouch (in female patients).
Catheter Kinking.
Catheter Entrapment.
