SH5-07 Lirubin was 24.8 ?12.9 for conjugated bilirubin and 25.2 ?14 for the non-conjugated form. The final values of plasma bilirubin were directly related to the initial ones (r = 0.824, P < 0001). The mean adsorption rates on the BR-350 column were 72.6 in the first 30 min and 39 after perfusion of 500 and 1000 ml of plasma respectively. A rebound in the bilirubin levels was present from the very first minutes after the end of the procedure; 24 hours later the rebound recorded in 18 treatment was 34.9 ?38.7 compared to the end of the treatment. In patients undergoing four or more repeated sessions of plasma separation and bilirubin adsorption, the level of seric bilirubin decreased from 57 ?12 to 17 ?10 mg/dl. In conclusion, extracorporeal anion exchange plasma perfusion/ bilirubin adsorption is a safe and effective treatment and it should be considered as a supportive therapy for excessive hyperbilirubimenic side effects in cholestatic disorders.P189 Non-invasive measurement of carboxyhemoglobin (COHb) by new pulse oximeter in human volunteersY Sato*, K Ikegami*, Y Kuno*, N Kobayashi, T Usuda *Trauma and Critical Care Center, Koshigaya Hospital, Dokkyo University School of Medicine, 2-1-50 Minami-Koshigaya, Koshigaya, Saitama, 343-8555, Japan; R D Center, Nihon Kohden Corporation, Tokyo, Japan Introduction: Carbon monoxide is the most commonly encountered and pervasive poison in our environment. However, conventional pulse oximeters cannot detect the presence of carboxyhemoglobin (COHb) and overestimate arterial oxygenation in patients with severe carbon monoxide poisoning. We developed a new pulse oximeter utilizing three wavelengths which can discriminate three species, oxyhemoglobin (O2Hb), deoxyhemoglobin (RHb) and COHb. We previously demonstrated that increases in COHb concentration measured by the new pulse oximeter (SpCO) highly correlated with increases in COHb concentration measured by a CO-oximeter (SaCO) in pigs. The present study determined whether COHb was detected by the pulse oximeter with three wavelengths in human. were ventilated with 100 oxygen. Probes of the new three wavelength pulse oximeter were attached to the finger. Then 50 ml of carbon monoxide gas was inhaled by human volunteers. SpCO was non-invasively and continuously measured by the new pulse oximeters. SaCO was also measured by a CO-oximeter after 3 min of inhalation. The same PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/20726879 amount of carbon monoxide gas was repeatedly inhaled until SaCO reached 15?0 . Then they were ventilated with 100 oxygen until SaCO reached 5 . SpCO was compared with SaCO. Results: COHb was non-invasively and continuously detected by the new pulse oximeter. There is a strong correlation between SpCO and SaCO (r = 0.92, P < 0.001). Conclusion: The results of this study demonstrated that the new pulse oximeter might be useful for non-invasive diagnosis of carbon monoxide poisoning.Methods: The study was approved by the hospital Ethics Committee.
