Abstract

Systematic investigations of hemodynamic status during double filtration plasmapheresis (DTP) are rare in the literature. To investigate the hemodynamic effects of the vascular access chosen for DFP, variations in blood pressure (BP) and pulse rate (PR) induced acutely by DFP were prospectively analyzed in 46 myasthenia gravis (MG) patients a standard DFP protocol with isovolumetric saline fluid replacement. BP and PR were monitored at 30-min intervals (baseline, M30, M60, M90, and M120) during the procedures. The patients were randomized into central vein (CV) and peripheral vein (PV) groupsbased on the vascular access used: Systolic BP (SBP) dropped significantlyat M60 (P < 0.05), M90 (P < 0.001), and M120 (P < 0.001) when compared to the baseline level. Symptomatic hypotension was not observed in any of the 46 sessions. SBP values during DFP in the CV group were significantly lowerthan the PV group's at M60 (93.1 vs. 101.0%; P < 0.05) and marginally lower at M90 (91.2 vs. 97.2%, P = 0.06). There was no significant difference indiastolic BP changes between the two groups. In the CV and PV groups, PR changes during plasmapheresis also differed at M90 (103.4 vs. 94.5%, P < 0.001) and M120 (101.3 vs. 95.0%, P < 0.05). The significantly lower SBP during DFP in the CV group at M60 may be due to the high central vein flow rate and resultant delay in volume replacement. In conclusion, the vascular access selected for DFP plays a role in the pathogenesis of plasmaphecesis-related hypotension. Controlling flow rates may help to prevent hypotension.
