ABSTRACT
A coverage evaluation survey was conducted in Mandya and Koppal districts of Karnataka state following the Japanese Encephalitis (JE) vaccination campaign. The purposes of the survey were to assess coverage of children in target age group by JE vaccination and to assess adverse events following immunisation against JE, the knowledge of health care providers and community about JE & mass vaccination for JE. The study design consisted of both quantitative and qualitative methods. The quantitative data was used to know the coverage levels for children. The qualitative data collected through interviews of head of the family in the sample households, selected health care workers using a structured pretested questionnaire. The standard cluster sampling method was used for selecting the sample of children to be evaluated. In Mandya district the evaluation showed 92 % coverage in the selected sample of 313 children against the reported 83.85 %. In Koppal district the evaluation showed 70 % coverage, among the selected sample of 251 children, against the reported coverage of 69.8 %. The incidence of adverse events was 4% in Mandya sample and 6.37 % in Koppal sample. In Mandya district, about 42 % of households had knowledge of JE. About 68 % of households had prior knowledge of the immunization day. In Koppal district, the survey has revealed that only 19.85 % of the heads of household had the knowledge of JE and 48.53% had the knowledge of JE vaccination before the day of vaccination campaign.
ABSTRACT
The efficacy of ultra-low-dose-aprotinin (ULDA) in 'high-risk' two valve replacement surgery, was evaluated in this prospective, randomized, double-blind study. Forty adult high-risk patients undergoing elective two valve replacement surgery, were included. The patients were divided into 2 groups of 20 each. In Group I, aprotinin in a dose of 1,000,000 KIU was administered from the end of anaesthesia induction to the time of sternotomy after a 1 ml of test dose. In Group II (control), 100 ml of normal saline was administered in a similar fashion. Coagulation parameters, blood loss, and amount of transfusion of blood / blood products were measured at specific intervals. The postoperative chest tube drainage in the first 24 hours was significantly less 203+/-35 ml (p<0.05) in Group I as compared with 490+/-104 ml in group II and consequently, Group I patients received significantly less (p<0.05) red cell concentrates and platelet transfusion. There was a significant decrease in the length of postoperative elective ventilation, intensive care unit (ICU) stay and direct costs involved in the hospital expenses with the use of ULDA. We conclude that ULDA is safe and effective in 'high-risk' two-valve replacement surgery to reduce postoperative bleeding, postoperative length of intubation and ICU stay; use of ULDA is associated with significant direct cost savings.
