| 520 | |a Cryoelectrolysis is a new minimally invasive tissue ablation surgical technique that combines the processes of electrolysis and solid/liquid phase transformation (freezing). This study investigated this new technique by measuring the pH front propagation and the changes in resistance in a tissue simulant made of physiological saline gel with a pH dye as a function of the sample temperature in the high subzero range above the eutectic. Results demonstrated that effective electrolysis can occur in a high subzero freezing milieu and that the propagation of the pH front is only weakly dependent on temperature. These observations are consistent with a mechanism involving ionic movement through the concentrated saline solution channels between ice crystals at subfreezing temperatures above the eutectic. Moreover, results suggest that Joule heating in these microchannels may cause local microscopic melting, the observed weak dependence of pH front propagation on temperature, and the large changes in resistance with time. A final insight provided by the results is that the pH front propagation from the anode is more rapid than from the cathode, a feature indicative of the electro-osmotic flow from the cathode to the anode. The findings in this paper may be critical for designing future cryoelectrolytic ablation surgery protocols. | ||

An Electrochemistry Study of Cryoelectrolysis in Frozen Physiological Saline |
| abstract |
Cryoelectrolysis is a new minimally invasive tissue ablation surgical technique that combines the processes of electrolysis and solid/liquid phase transformation (freezing). This study investigated this new technique by measuring the pH front propagation and the changes in resistance in a tissue simulant made of physiological saline gel with a pH dye as a function of the sample temperature in the high subzero range above the eutectic. Results demonstrated that effective electrolysis can occur in a high subzero freezing milieu and that the propagation of the pH front is only weakly dependent on temperature. These observations are consistent with a mechanism involving ionic movement through the concentrated saline solution channels between ice crystals at subfreezing temperatures above the eutectic. Moreover, results suggest that Joule heating in these microchannels may cause local microscopic melting, the observed weak dependence of pH front propagation on temperature, and the large changes in resistance with time. A final insight provided by the results is that the pH front propagation from the anode is more rapid than from the cathode, a feature indicative of the electro-osmotic flow from the cathode to the anode. The findings in this paper may be critical for designing future cryoelectrolytic ablation surgery protocols. |

Moreover, results suggest that Joule heating in these microchannels may cause local microscopic melting, the observed weak dependence of pH front propagation on temperature, and the large changes in resistance with time. A final insight provided by the results is that the pH front propagation from the anode is more rapid than from the cathode, a feature indicative of the electro-osmotic flow from the cathode to the anode. The findings in this paper may be critical for designing future cryoelectrolytic ablation surgery protocols.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cathodes</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">cryosurgery</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">electrolytic ablation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Temperature measurement</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">frozen tissue</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Electrochemical processes</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">cryoelectrolytic ablation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cells (biology)</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">cryogenics</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">tissue ablation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Surgery</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Anodes</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cryoelectrolysis</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">electrolysis</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Research</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Temperature measurements</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Biochemistry</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Analysis</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Usage</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Munnangi, Pujita</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rubinsky, Boris</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">IEEE transactions on biomedical engineering</subfield><subfield code="d">New York, NY : IEEE, 1964</subfield><subfield code="g">64(2017), 7, Seite 1654-1659</subfield><subfield code="w">(DE-627)129358452</subfield><subfield code="w">(DE-600)160429-6</subfield><subfield code="w">(DE-576)01473074X</subfield><subfield code="x">0018-9294</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:64</subfield><subfield code="g">year:2017</subfield><subfield code="g">number:7</subfield><subfield code="g">pages:1654-1659</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">http://dx.doi.org/10.1109/TBME.2016.2627402</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">http://ieeexplore.ieee.org/document/7784754</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-TEC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHA</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-DE-84</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OPC-PHA</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2061</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2410</subfield></datafield><datafield tag="936" ind1="r" ind2="v"><subfield code="a">XA 48665</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">44.09</subfield><subfield code="q">AVZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">44.40</subfield><subfield code="q">AVZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">64</subfield><subfield code="j">2017</subfield><subfield code="e">7</subfield><subfield code="h">1654-1659</subfield></datafield></record></collection>
