    Adrenaline toxicity following accidental administration of the 1:1000 solution during dental procedures; four case reports
    (2012) Fernando, Dinesh M. G.; Dayaratne, K. M. P. L.
    Four patients aged between 35 and 50 years attended the out patients department of a dental hospital for tooth extraction. Following administration of, what was thought to be the local anesthetic, Lignocaine, to the gum and sub mucosa, they all collapsed. What had, in fact, been injected was 1:1000 adrenaline. We would like to report the symptoms, signs and investigation findings that followed. Significantly elevated Troponin T, CPK (total), CPK (MB) and ECG changes were seen. Electromyography and Nerve Conduction Studies showed a myopathic pattern and reduction in motor and sensory conduction respectively. These patients were followed up for a period of five years. Long term effects such as tremor, muscle weakness, easy fatigability and shortness of breath on exertion, which is not reported in the literature, were reported by all patients.

    Death due to adult repiratory distress syndrome following assault with 'Rubber Acid': could it have been averted
    (2012) Fernando, Dinesh M. G.; Kaluarachchi, C. I.
    Abstract Adult respiratory distress syndrome and chemical pneumonitis are well documented effects of exposure to chemical fumes. Many organic and non-organic agents cause chemical pneumonitis. The course of the disease depends on the nature of the chemical agent, intensity and duration of the exposure and the interval between exposure and start of treatment. Also the site of damage tends to vary with the gas involved; gases with higher water solubility being effectively scavenged by the upper respiratory mucosa, while insoluble toxic gases have their effects on the lower respiratory mucosa
