25、ed prospects for breath diagnosis as a non-invasive diagnostic tool. In this study, ion mobility spectrometry (IMS) and cavity ring-down spectroscopy (CRDS) techniques were used to analyse ammonia gas NH3 in real-time in breath from patients undergoing haemodialysis (HD) treatment and any correlatio

26、n with blood urea nitrogen (BUN) levels and Kt/V were investigated. Methods We studied 20 patients on intermittent HD treatment. The first breath samples were taken before the start of dialysis and further breath samples were taken every hour during the treatment and after the end of the session. An

Results Breath ammonia. concentrations were higher in CRDS-HD (914.5 土 301.4 versus 280 土 120 parts per billion (p.p.b.), P 0.0001) and IMS-HD patients(964.4 土 402.4 versus 280 土 120 p.p.b., P 0.0001) than

28、in HS. We assessed real-time variations in the levels of NHJ3 and showed a continuous decrease in the levels of NH3. Expired NH3 correlated directly with BUN levels, both in the IMS-HD (P = 0.002; r = 0.84; P = 0.009; r = 0.76) and in the CRDS-HD group (P = 0.005; r = 0.80; P = 0.008; r = 0.77), res

29、pectively, both before and at the end of dialysis. A direct correlation with Kt/V was found in both groups studied (IMS-HD: P = 0.003; r = 0.82; CRDS-HD: P = 0.006; r = 0.79). Conclusions Breath monitoring of NH3 with IMS and CRDS techniques could be useful to assess the real-time clinical status of

30、 patients during HD. By using pre-dialysis ammonia values, an approximate calculation of the Kt/V(urea) ratio can be established. 相似文獻(xiàn)：Neri Giovanni.
