RESUMEN

Dexmedetomidine as an adjuvant to local anesthetics in peripheral nerve blocks has been used in only a few studies. We aimed at assessing the effect of dexmedetomidine as an adjuvant to ropivacaine in supraclavicular brachial plexus block. Random, controlled, and triple blind. Sixty American Society of Anesthesiologist grade I and II patients of either sex scheduled for elective upper limb surgery under supraclavicular brachial plexus block were divided into three equal groups in a prospective randomized double-blind controlled manner. For block patients in Group C received 0.5% ropivacaine [30cc], 0.5% ropivacaine with 50 microg dexmedetomidine [30cc] in Group D and 0.5% ropivacaine [30cc] in Group D-IV along with intravenous infusion of 50 microg dexmedetomidine in normal saline. IBM-SPSS software version 17, Chi-square test, Mann-Whitney U-test. Demographic profile and surgical characteristics were similar in all the three groups. Sensory block and motor block onset was earlier in group D than in group D-IV and group C. The sensory block and motor block duration was also prolonged in group D when compared with group D-IV and group C. The duration of analgesia was significantly longer in group D and D-IV when compared to group C. Dexmedetomidine as an adjuvant to 0.5%ropivacaine in ultrasound guided brachial plexus block shortens the sensory as well as motor block onset time, prolongs sensory and motor block duration and also increases the duration of analgesia. The action of dexmedetomidine most probably is local rather than centrally mediated

RESUMEN

OBJECTIVE@#To report high co-positivity of anti-dengue virus (DV) and anti-Japanese encephalitis virus (JEV) IgM in an area endemic for both the viruses and to discuss the possibilities of co-infection.@*METHODS@#Serum samples from the patients who presented with fever, suspected central nervous system infection and thrombocytopenia, were tested for anti-DV IgM and anti-JEV IgM antibodies. Conventional reverse transcriptase polymerase chain reaction was done for detection of DV RNA and JEV RNA.@*RESULTS@#Of 1 410 patient sera tested for anti-DV and anti-JEV antibodies, 129 (9.14%) were co-positive for both. This co-positivity was observed only in those months when anti-JEV IgM positivity was high. Titers of both anti-DV IgM and anti-JEV IgM were high in most of the co-positive cases. Among these 129 co-positive cases, 76 were tested by conventional reverse transcriptase polymerase chain reaction for both flaviviruses, of which eight cases were co-positive for DV and JEV.@*CONCLUSIONS@#Co-infection with more than one flavivirus species can occur in hyperendemic areas.
