Disclosed are methods and devices comprising an elongated probe for the in vivo detection of meconium in amniotic fluid held in an amniotic sac based on detecting the presence of Zinc-coproporphyrin I (ZnCP). ZnCP is excited at approximately 405 nm and emits characteristic fluorescence, centered at about 580 nm and less intensely at 630 nm.

Device and method for identification of meconium in amniotic fluid

An apparatus, system and method are provided for diagnosing the degree of body metabolic emergency state. A non-vital organ with respect to the metabolic emergency state is first chosen. One or more tissue viability parameters including at least one of NADH and Flavoprotein (Fp) concentration are monitored in the non-vital organ, whereupon the degree of body metabolic emergency state may be determined based on the monitored tissue viability parameters.

Diagnosis of body metabolic emergency state

Apparatus for monitoring a plurality of tissue viability parameters of a tissue layer element, in which two different illumination sources are used via a common illumination element in contact with the tissue. One illumination source is used for monitoring blood flow rate and optionally flavoprotein concentration, and collection fibers are provided to receive the appropriate radiation from the tissue. The other illuminating radiation is used for monitoring any one of and preferably all of NADH, blood volume and blood oxygenation state of the tissue element, and collection fibers are provided to receive the appropriate radiation from the tissue. In one embodiment, the wavelengths of the two illumination sources are similar, and common collection fibers for the two illuminating radiations are used. In another embodiment, the respective collection fibers are distanced from the illumination point at different distances correlated to the ratio of the first and second illuminating wavelengths.
