OBJECTIVETo discuss the effectiveness of severe and acute organophosphate poisoning (AOPP) treated with plasma exchange in China.
METHODSResearches about effectiveness of severe AOPP treated with plasma exchange were analyzed by Review Manager 4.2 and fixed effect model of meta-analysis method were used.
RESULTSSix trials including 433 patients were identified. Treatment group including 211 patients adopted traditional physician therapy plus plasma exchange, and control group including 222 patients received physician therapy only. The case-fatality rate of the treatment group was lower than the control one [RR=0.30, 95%CI (0.19-0.49), P<0.01].
CONCLUSIONPlasma exchange can improve the cure rate of severe AOPP.

BACKGROUND: Definite criteria for determining severity of organophosphate poisoning have not been made. Discovery of the third neuromuscular syndrome, the intermediate syndrome, have made it more complicating then ever. Objectives of this study is to determine early prognostic factors of outcome and development of a new treatment algorithm. METHOD: 74 patients admitted to Severance hospital with acute organophosphate poisoning during 5 years were included. We made a protocol concerning the initial consciousness level, QTc interval, PVC, serum cholinesterase, the intermediate syndrome, total hospital, ICU day, length of ventilator support, disposition and have done a study retrospectively. Multiple regression and Chi-square was used as statistical analysis. Significant statistical P-value was 0.05. RESULTS: The total hospital days were prolonged as serum cholinesterase levels were lower, the age was older and mental status graver.(p<.05) The length of ventilatory support was prolonged when patient's serum cholinesterase level was very low, they were unconscious and serum cholinesterase level not recovered to 500 IU/ml within initial 3 days. The intermediate syndrome was significantly related to the prolonged cholinesterase inhibition. CONCLUSION: As an early prognostic factor for the length of ventilatory support in organophosphate poisoning, 1) level of concsiousness and 2) serum cholinesterase level at admission, 3) recovery to more than 500 IU/ml within initial 3 days are useful. Especially when the serum cholinesterase level is not recovered to more than 500 IU/ml within initial 3 days, it is essential to observe closely for the possibility of an intermediate syndrome.

Delayed peripheral polyneuropathy caused by organophosphorus intoxication is not uncommon. This is a case report of 32 years old female with peripheral polyneuropathy which is appeared two weeks after organophosphorus poisoning. It is characterized by calves pain followed by minmal sensory change and predominant motor weakness affecting the distal part of the limbs. The electrophysiologic and pathologic studies support the clinical diagnosis. The exact pathogenesis is still debated, but phosphorylation of neurotoxic esterase (NTE), followed by "aging" process was suspected to play a role in the development of axonal degeneration.
