Flora bacteriana después del lavado de manos quirúrgico. Estudio piloto / Bacterial flora after surgical hand scrubbing. A pilot study

RESUMEN Introducción: La técnica de lavado de manos quirúrgico es imprescindible para la prevención de las infecciones posoperatorias en el sitio de la intervención, lo que constituye un problema actual y en evolución. Objetivo: Determinar la técnica de lavado de manos quirúrgico con mayor eficacia sobre la flora bacteriana en estudiantes de cirugía. Métodos: Ensayo controlado, aleatorio, de tratamientos no farmacológicos. Se seleccionaron 12 estudiantes de cirugía de la Facultad de Odontología, Universidad de San Martín de Porres, que cumplían con los criterios de inclusión y exclusión. Los estudiantes se dividieron en dos grupos y se les asignó una técnica de lavado de manos quirúrgico: Grupo A: técnica de una fase, y Grupo B: técnica tradicional (tres fases); para ambas técnicas se utilizó escobilla y jabón en barra. Resultados: En el medio de cultivo agar manitol salado, la técnica tradicional presentó una mediana de 52 000 UFC/mL con un mínimo de 10 000 UFC/mL y un máximo de 56 800 UFC/mL, en comparación con la técnica de una fase que presentó 19 600 UFC/mL con un mínimo de 4 400 UFC/mL y un máximo de 38 000 UFC/mL, con un valor de p= 0,117. En el agar MacConkey, la técnica tradicional presentó una mediana de 300 UFC/mL con un mínimo de 0 UFC/mL y un máximo de 18 000 UFC/mL, en comparación con la técnica de una fase que presentó 0 UFC/mL, con un valor de p= 0,054. Conclusiones: No se mostraron diferencias estadísticamente significativas en ambos grupos(AU)

ABSTRACT Introduction: Surgical hand scrubbing is indispensable to prevent postoperative infection at the intervention site, a problem both current and in progress. Objective: Determine the most effective surgical hand scrubbing technique against bacterial flora among surgery students. Methods: A controlled randomized study was conducted of non-pharmacological treatments. Twelve surgery students were selected from the School of Dentistry at the University of San Martín de Porres who met the inclusion and exclusion criteria. The students were divided into two groups and assigned one of two surgical hand scrubbing techniques: Group A: one-step technique and Group B: traditional technique (three steps). Both techniques used bar soap and a brush. Results: In the culture medium mannitol salt agar, the traditional technique obtained a median of 52 000 CFU/mL, with a minimum 10 000 CFU/mL and a maximum 56 800 CFU/mL, whereas the one-step technique obtained a median of 19 600 CFU/mL, with a minimum of 4 400 CFU/mL and a maximum of 38 000 CFU/mL (p= 0.117). In MacConkey agar, the traditional technique obtained a median of 300 UFC/mL, with a minimum of 0 CFU/mL and a maximum of 18 000 CFU/mL, whereas the one-step technique obtained 0 UFC/mL (p= 0.054). Conclusions: No statistically significant differences were found in the groups(AU)

Association Between Self-Perceived Oral Health and Clinical Indicators.

PURPOSE: To determine whether self-perceived oral health impact and satisfaction measure oral health in the same way as do clinical indicators in adults and older adults. MATERIALS AND METHODS: The population consisted of adult patients aged 20 to 59 years receiving care at "Juan Pablo II" Health Care Centre and older adult patients aged 60 or more years from the home for the elderly "Virgen del Amor Hermoso", Lima, Peru. The indices Oral Impacts on Daily Performance (OIDP) and Oral Satisfaction Scale of 0-10 (OSS 0-10) were used to evaluate perceived impact of and satisfaction with oral health. In addition, the following internationally validated criteria established by the World Health Organization (WHO) were used as clinical indicators: Decayed-Missing-Filled Teeth (DMFT) Index, O'Leary's Hygiene Index, Community Periodontal Index, Motivation to Hygiene Index, Denture Situation Index, Need for Denture Index, Denture Hygiene Index and Oral Mucosal Lesion Index. RESULTS: Forty-four adults and 53 older adults participated. OIDP showed that the greatest perceived difficulty in daily performance was "eating and enjoying food" (adults: 77.3% and older adults: 79.2%). The OSS 0-10 showed that among adults, 43.1% were dissatisfied, 20.5% were neutral and 36.4% were satisfied, while among older adults, 45.3% were dissatisfied, 22.6% were neutral and 32.1% were satisfied. A statistically significant association was found between OSS 0-10 and 1. DMFT index in adults; 2. upper denture situation in older adults; and 3. denture hygiene in older adults. A highly significant inverse linear correlation was found between OIDP and OSS 0-10 in adults and older adults. CONCLUSION: The perceived impact of oral health does not have a demonstrable association with oral health problems when used as an instrument for measuring oral health status, whereas perceived satisfaction with oral health has a better association with the clinical indicators.
