To determine the occurrence of percutaneous injuries (PI) and accidental exposure to patients' blood (AEPB) in surgical residents in Enugu, Nigeria, their awareness of universal precautions (UP), and use of post-exposure prophylaxis (PEP).
Self-administered semi-structured pre-tested questionnaires were administered to 230 consenting trainee surgeons.
The rate of exposure to PI/ABE was 67.5%. The number of exposures ranged from 1 to 5 with a mean of 1.9 ± 0.99. Senior registrars had the highest rate of exposure (76.9%). In 89 exposures (63.6%) needle-prick injuries were reported. Adequate knowledge of the UP and PEP to HIV virus was only 41%. In most cases (72.1%) respondents subsequently disregarded the exposure.
The high rate of exposure to PI/ABE, inadequate knowledge and poor practice of UP/PEP seen in this study underscore the need for creating high level of awareness about UP/PEP, the development of clear institutional guideline and the provision of adequate materials and supervision to ensure adherence with the guideline. The practice of UP and PEP in PI and AEPB are life saving and should be emphasized in residency training.
确定尼日利亚埃努古外科住院医师经皮损伤（PI）和意外接触患者血液（AEPB）的发生率、他们对通用预防措施（UP）的知晓情况以及暴露后预防（PEP）的使用情况。
对230名同意参与的实习外科医生发放自行填写的经过预测试的半结构化问卷。
PI/ABE的暴露率为67.5%。暴露次数为1至5次，平均为1.9±0.99次。高级住院医师的暴露率最高（76.9%）。在89次暴露中（63.6%）报告为针刺伤。对HIV病毒的UP和PEP的充分知晓率仅为41%。在大多数情况下（72.1%），受访者随后忽视了暴露情况。
本研究中PI/ABE的高暴露率、对UP/PEP的知晓不足和实践不佳，突出表明需要提高对UP/PEP的认识水平，制定明确的机构指南，并提供足够的材料和监督，以确保遵守该指南。在PI和AEPB中实施UP和PEP能挽救生命，应在住院医师培训中予以强调。
