In a previous study, 18 repeated exposures of anaesthetized swine to an electro-muscular incapacitating device (TASER International's ADVANCED TASER X26 electronic control device) resulted in acidosis and increases in blood electrolytes. In the current study, experiments were performed to investigate effects of a more typical scenario of repeated exposures of the device on muscle contraction and changes in blood factors. Ten swine were exposed for 5s, followed by a 5-s period of no exposure, three times. Selected blood factors were monitored for 3h following exposure. Transient increases in blood glucose, lactate, sodium, potassium, calcium, and pCO(2) were consistent with previous reports in the literature dealing with studies of muscle stimulation or exercise. Blood pH was decreased immediately following exposure, but subsequently returned toward a normal level. Oxygen saturation (measured by pulse oximetry) was not changed significantly. In conclusion, three repeated TASER device exposures had only transient effects on blood factors, which all returned to pre-exposure levels, with the exception of hematocrit (which remained elevated after 3h). Since the increase in this factor was less than that which may occur after short periods of exercise, it is unlikely that this would be an indicator of any serious harm.
在之前的一项研究中，对麻醉的猪重复18次暴露于一种电肌肉失能装置（泰瑟国际公司的先进泰瑟X26电子控制装置）导致酸中毒和血液电解质增加。在当前研究中，进行了实验以调查该装置更典型的重复暴露情况对肌肉收缩和血液因子变化的影响。十头猪暴露5秒，随后有5秒不暴露的时间段，重复三次。暴露后对选定的血液因子监测3小时。血糖、乳酸、钠、钾、钙和pCO₂的短暂升高与文献中先前关于肌肉刺激或运动研究的报告一致。暴露后血液pH值立即下降，但随后恢复到正常水平。氧饱和度（通过脉搏血氧测定法测量）没有显著变化。总之，泰瑟装置三次重复暴露对血液因子只有短暂影响，除血细胞比容外（3小时后仍升高），所有血液因子均恢复到暴露前水平。由于该因子的增加小于短时间运动后可能出现的增加，因此这不太可能是任何严重伤害的指标。
