ABSTRACT
Injury with contaminated sharp devices like used needles is the great potential risk factor in nursing staff. Severity of infectious complications of these injuries demonstrated the value of prophylactic activities. To evaluate epidemiologic features of needle stick injuries and coverage of Hepatitis B vaccine among nursing staff in Bualisina hospital in Qazvin from March 2007 to March 2008. In this cross sectional descriptive study, data of needle stick injuries if staff was gathered by direct interview. For statistical analysis were used t student, chi square and Fisher exact test. P value above 0.05 was considered statistically significant. In this period among 172 nurses, 55 subjects experienced needle stick injuries [32%]. There was no statiscally relationship between needle stick injuries with educational level, gender, and related training courses; but there was a statiscally relationship between the injuries and the number of continous shifts. Reporting the injury to the hospital supervisors was statiscally significant in nurses who had university education. According to undesirable complications of needle stick injuries, it is considered to organize educational programs in order to decreasing continues shifts in nursing staff and emphasis major priority of prevention methods

OBJETIVO: Medir la asociación entre el antecedente de procedimientos anestésicos y el riesgo de infección por el virus de la hepatitis C (VHC) en pacientes con cirugía previa. MATERIAL Y MÉTODOS: Diseño de casos y controles; los casos fueron pacientes con anticuerpo (anti-VHC) positivo confirmado por RIBA y/o RNA VHC y los controles fueron sujetos con el anti-VHC negativo. El riesgo de infección se estimó por razón de momios (RM) y análisis multivariado con regresión logística. RESULTADOS: Se incluyeron 362 sujetos, 211 casos y 151 controles; en 70 casos (33.2 por ciento), con cirugía previa, los procedimientos anestésicos se identificaron como único factor de riesgo significativo para la infección por el VHC (RM ajustada 2.44, IC 95 por ciento 1.44 - 4.11). CONCLUSIONES: Este es el primer estudio en México que demuestra asociación de riesgo significativa con el antecedente de procedimientos anestésicos por cirugía previa, en uno de cada tres enfermos con hepatitis C.
OBJECTIVE: Nosocomial transmission of hepatitis C virus (HCV) infection had been related with anesthesia procedures. The study aim was to measure the association between anesthesia procedures in cases with previous surgery and HCV infection. MATERIAL AND METHODS: In a case-control study were included subjects that attended to the Central Blood Bank of the West Medical National Center, Mexican Institute of the Social Security in Guadalajara, Jalisco between july 2005 and september 2007. Cases were patients with positive hepatitis C antibody (anti-HCV) confirmed by recombinant immunoblot assay (RIBA) and/or nucleic acid test (HCV RNA); the control group was blood donors with negative antibody. An exhaustive questionnaire about risk factors for hepatitis C, was applied. The risk of HCV infection was determined with the Odds Ratio (OR) and multivariate analysis was made by logistic regression. RESULTS: We included 362 subjects, 211 cases and 151 controls; in 70 (33.2 percent) cases were found significant association between the anesthesia procedures and HCV infection in patients with previous surgery (OR adjusted 2.44, CI 95 percent 1.44 - 4.11) CONCLUSION: This is the first study in México that demonstrate association between history of anesthesia procedures and HCV infection in cases with previous surgery.
