Aims & Objectives: 2 years old, Weight 7.4 kg CRF and CIA ostium secundum 5.6 mm with moderate hemodynamic repercussion. pulmonary stenosis with a 22 mmhg, probably secondary to hyperflux, receives enalapril, furosemide, calcitriol, calcium and salbutamol, beclomethasone. He has edema, distended abdomen. Exfx:Unstable, FC DE 176, TA 100/60, SAO2 DE 90%, with signs of water overload, peritoneal dialysis catheter dysfunction, DOM and intubates, milrinone EP,NE,Ad. liquids: 500 cc Liquids eliminated: 10 cc taken to surgery for rearrangement of PD catheter, but it is dysfunctional, PD cannot be done. Accumulated water balance of 100 ml LEU 11,500, 78% PMN, 14% LN, HB DE 9.6,HTO 30%, BUN: 76.8, Cr: 3.61, alb: 3.57, PCR DE 300, pt 27, P: 7.7, Mg: 1.5, Chlorine: 106, PD does not work. hemodialfltration v-v is not possible. THE CAVHDF and is programmed like thispump flow: 50 cc / min Ultrafiltrate: 28 cc / h 75 cc / h citrate calcium gluconate 30 cc / h effluent volume: VE: 30 cc / kg / h UL: 28 cc / h QR: 50% = 97 cc / h QD: 50% = 97 cc / h With all this, the patient finished coin his terpaia, I remain with erc and then he transplanted and is fine Methods: CASE REVIEW Results: THE USE OF CONTINUOUS ARTERIAL VENOUS HEMODIAFILTRATION IN PATIENT, WHERE PERITONEAL DIALYSIS AND HEMODIALISIS WAS NOT POSSIBLE, THIS IS AN ALTERNATIVE EVEN Conclusions: THE USE THE HDFAVC, WHERE PERITONEAL DIALYSIS AND HEMODIALISIS WAS NOT POSSIBLE, THIS IS AN ALTERNATIVE EVEN
