Acute toxicity of methyl isocyanate in mammals. II. Induction of hyperglycemia, lactic acidosis, uraemia, and hypothermia in rats

When rats were administered methyl isocyanate (MIC) by inhalation or subcutaneous route it produced severe hyperglycemia, clinical lactic acidosis, highly elevated plasma urea, and reduced plasma cholinesterase activity with unaltered erythrocytc acetyl cholinesterase activity. Irrespective of the route of administration, MIC also caused severe hypothermia, which was not ameliorated by prior administration of atropine sulphate. Acute toxic effects of MIC are essentially similar by either route except for the intensity of the effects

Design of a Wearable Remote Neonatal Health Monitoring Device

In this text we present the design of a wearable health monitoring device capable of remotely monitoring health parameters of neonates for the first few weeks after birth. The device is primarily aimed at continuously tracking the skin temperature to indicate the onset of hypothermia in newborns. A medical grade thermistor is responsible for temperature measurement and is directly interfaced to a microcontroller with an integrated bluetooth low energy radio. An inertial sensor is also present in the device to facilitate breathing rate measurement which has been discussed briefly. Sensed data is transferred securely over bluetooth low energy radio to a nearby gateway, which relays the information to a central database for real time monitoring. Low power optimizations at both the circuit and software levels ensure a prolonged battery life. The device is packaged in a baby friendly, water proof housing and is easily sterilizable and reusable.
