“…After impedance started to decrease rapidly, MCs continued to increase 2–6 h and finally reached stable levels. A similar change was reported in rabbit muscle [Schäfer et al, ], where the time of MC reaching a steady state was about 100 min later than the start‐descent time of Re (real part of impedance) increase. It is inaccurate to interpret increase in impedance with a fluid‐squeeze effect due to the muscular contraction during ischemia or rigor mortis.…”

“…One reason for impedance reduction was that the metabolic processes produced more ions and small molecular compounds, which increased the specific conductivity of the tissue fluid and led to a decrease in impedance behavior [Schäfer et al, 1998;Vidaček et al, 2008]. Moreover, we concluded that the increase in intercellular spaces caused by membranolysis promoted more low-frequency current to pass extracellular fluid, which led to the drop in impedance.…”

“…Martinsen et al [2000] pointed out that low-frequency resistance of fish increased during early storage as the tissue proceeded to rigor, then decreased with cell destruction. Muscle contraction (MC) influenced electrical impedance as also exhibited by Schäfer et al [1998], who explained that low-frequency impedance increased during early storage mainly due to the narrowing of extracellular pathways caused by cell edema. The status of gap junctions between cells also had an important effect on electrical impedance spectroscopy, as supplementarily interpreted by Gersing [1998].…”

Changes in impedance at 2 kHz, adenosine triphosphate (ATP) content, and muscle contraction were evaluated in yellowtail during 0 (ice), 5, 10, 15, and 20°C storage. Histological changes during ice storage were also measured. At any temperature, although impedance increased with both rigor mortis and ATP consumption during early storage, it began to decrease rapidly when ATP was almost depleted. Moreover, temporarily increasing impedance had a strong relationship with ATP content; decreasing impedance had a significant correlation with storage temperature after ATP depletion. Furthermore, impedance increased with narrowing of intercellular spaces when sarcolemma was intact and decreased with expansion of intercellular spaces when sarcolemma was leaky. Meanwhile, changes of sarcolemma and intercellular spaces were accompanied by ATP change. Thus, ATP is one significant physiological factor for impedance change, and temperature greatly influenced impedance after depletion of ATP. Results suggest that impedance analysis can be used as a convenient and nondestructive method to diagnose condition of tissue at different storage temperatures.

“…Electric bioimpedance has been utilized to investigate changes in electrical parameters during ischemia in various tissues (Gersing, 1998, Gheorghiu and Gersing, 2002, Schafer et al, 1998, Martinsen et al, 2000, Salazar et al, 2004, Casas et al, 1999, Kun and Peura, 1994, Asami, 2007, Schafer et al, 1999, Ivorra, 2005. Ischemia leads to physical alterations on several levels in the tissue, resulting in changes over time in the electrical properties.…”

In vivocharacterization of ischemic small intestine using bioimpedance measurements

The standard clinical method for the assessment of viability in ischemic small intestine is still visual inspection and palpation. This method is non-specific and unreliable, and requires a high level of clinical experience. Consequently, viable tissue might be removed, or irreversibly damaged tissue might be left in the body, which may both slow down patient recovery. Impedance spectroscopy has been used to measure changes in electrical parameters during ischemia in various tissues. The physical changes in the tissue at the cellular and structural levels after the onset of ischemia lead to time-variant changes in the electrical properties. We aimed to investigate the use of bioimpedance measurement to assess if the tissue is ischemic, and to assess the ischemic time duration. Measurements were performed on pigs (n = 7) using a novel two-electrode setup, with a Solartron 1260/1294 impedance gain-phase analyser. After induction of anaesthesia, an ischemic model with warm, full mesenteric arterial and venous occlusion on 30 cm of the jejunum was implemented. Electrodes were placed on the serosal surface of the ischemic jejunum, applying a constant voltage, and measuring the resulting electrical admittance. As a control, measurements were done on a fully perfused part of the jejunum in the same porcine model. The changes in tan δ (dielectric parameter), measured within a 6 h period of warm, full mesenteric occlusion ischemia in seven pigs, correlates with the onset and duration of ischemia. Tan δ measured in the ischemic part of the jejunum differed significantly from the control tissue, allowing us to determine if the tissue was ischemic or not (P < 0.0001, F = (1,75.13) 188.19). We also found that we could use tan δ to predict ischemic duration. This opens up the possibility of real-time monitoring and assessment of the presence and duration of small intestinal ischemia.

“…At the end of the traction period, when a 100% increase in the length of the hand segments had been achieved, RVG data showed a 70% decrease in the amplitude characteristics of the arterial and venous components, which was evidence for tissue hypoxia [22]. According to some authors, a decrease in the blood flow at rest by more than 75% is a sign of tissue ischemia [23].…”

On the basis of the data of rheovasography (RVG) and laser Doppler flowmetry, comparative analysis of age-related changes in the peripheral blood circulation in hand tissues has been performed in 36 apparently healthy subjects aged 4-30 years and in 19 patients aged 18-50 years under the conditions of prolonged traction during surgical lengthening of finger bone stumps. The age-related changes in RVG are characterized by a higher volumetric blood content of tissues in children and adolescents, a decrease in the peripheral vascular tone, and wavelike recovery of capillary blood flow during reactive hyperemia, which is evidence for an unstable capillary tone. The dynamics of RVG indices during graded stretching in vivo (distraction) shows the dominance of an enhanced peripheral tone of arterioles and venules, and the response of the hand skin capillary bed to a 3-min ischemic test is analogous to the dynamics of indices of capillary blood flow in the hand skin of children.
