摘要
尽管感染控制和手术技术取得了进步，但手术部位感染(SSI)仍然是高发病率和死亡率的一个原因。目的探讨清洁颌面外科手术中手术时间是否会增加手术部位感染的比例。材料和方法这是一项观察性分析研究，包括1997年至2010年在San Borja临床医院Arriarán(智利圣地亚哥)接受清洁污染颌面手术的ASA I级患者。结果变量为手术部位感染。预测变量为性别、年龄、手术时间和SSI。统计学分析采用卡方检验、学生t检验和简单逻辑回归。结果522例患者符合纳入标准。感染率为6.9%。差异仅在手术时间上有统计学意义(P = 0.046)，优势比为1.003 (95% CI = 1.000-1.006)。结论随着手术时间的延长，SSI比例有显著性差异。然而，这种关联在临床上并不显著。
Riesgo de infección del sitio quirúrgico, según tiempo operatorio en cirugía maxilofacial mayor limpia contaminada: estudio observacional analítico
Introduction
Despite advances in infection control and surgical techniques, surgical site infection (SSI) continues to be a cause of high morbidity and mortality.
Objectives
To determine if operating time increases the proportion of surgical site infections in clean-contaminated maxillofacial surgery.
Materials and method
This was an observational analytical study, including ASA I patients undergoing clean-contaminated maxillofacial surgery between 1997 and 2010 at the Clinical Hospital San Borja Arriarán (Santiago, Chile). The outcome variable was surgical site infection. Predictor variables were gender, age, operating time and SSI. Statistical analysis was performed using chi-squared test, Student t test, and simple logistic regression.
Results
A total of 522 patients met the inclusion criteria. The infection rate was 6.9%. Statistically significant differences were only observed in the operation time (P = .046) with an Odds ratio of 1.003 (95% CI = 1.000-1.006).
Conclusion
Significant differences in the proportion of SSI were found when operation time increased. However, this association is not clinically significant.
