Hyperkalemia. A prognostic factor during acute severe hypothermia.

When hypothermic patients appear to be dead, the decision to resuscitate may be difficult due to lack of reliable criteria of death. To discover useful prognostic indicators, we reviewed the hospital charts of nine hypothermic victims of snow avalanches (group A: median value of rectal temperature, 29.6 degrees C; range, less than 12 degrees C to 34 degrees C) and of 15 patients with hypothermia following acute drug intoxication and/or cold exposure (group B: 28.8 degrees C; range, 25.5 degrees C to 32 degrees C. In group A, plasma potassium level on admission was extremely high (14.5 mmol/L; range, 6.8 to 24.5 mmol/L) compared with that obtained in group B (3.5 mmol/L; range, 2.7 to 5.3 mmol/L). All patients in group A were in cardiorespiratory arrest. None could be successfully resuscitated despite effective rewarming by cardiopulmonary bypass or peritoneal lavage. In contrast, all of the patients in group B recovered from hypothermia, including two in cardiorespiratory arrest. Thus, extreme hyperkalemia during acute hypothermia appears to be a reliable marker of death. It might be used to select those patients in whom heroic resuscitation efforts can be useful.

Adaptive tuning of perceptual timing to whole body motion.

In a previous work we have shown that sinusoidal whole-body rotations producing continuous vestibular stimulation, affected the timing of motor responses as assessed with a paced finger tapping (PFT) task (Binetti et al. (2010). Neuropsychologia, 48(6), 1842-1852). Here, in two new psychophysical experiments, one purely perceptual and one with both sensory and motor components, we explored the relationship between body motion/vestibular stimulation and perceived timing of acoustic events. In experiment 1, participants were required to discriminate sequences of acoustic tones endowed with different degrees of acceleration or deceleration. In this experiment we found that a tone sequence presented during acceleratory whole-body rotations required a progressive increase in rate in order to be considered temporally regular, consistent with the idea of an increase in "clock" frequency and of an overestimation of time. In experiment 2 participants produced self-paced taps, which entailed an acoustic feedback. We found that tapping frequency in this task was affected by periodic motion by means of anticipatory and congruent (in-phase) fluctuations irrespective of the self-generated sensory feedback. On the other hand, synchronizing taps to an external rhythm determined a completely opposite modulation (delayed/counter-phase). Overall this study shows that body displacements "remap" our metric of time, affecting not only motor output but also sensory input.
