插管后喉镜片清洁、灭菌与消毒的当前实践：印度医疗机构调查

文献信息

中文摘要

背景： 可重复使用的喉镜片在气道操作过程中会接触口咽分泌物、血液和黏膜表面。再处理不彻底可能使其成为可预防的交叉污染来源。本调查评估了印度医疗机构中喉镜片清洁、消毒、灭菌、储存和监测的当前实践。
材料与方法： 本横断面调查于2026年1月进行，纳入97名参与气道管理或喉镜处理的医疗专业人员。通过在线表格和直接访谈，使用结构化20项问卷收集数据。采用描述性统计分析应答。使用卡方检验评估所选实践相关变量之间的关联，P < 0.05视为具有统计学显著性。
结果： 96名受访者（99.0%）报告使用可重复使用喉镜。59家机构（60.8%）有书面消毒方案。23名受访者（23.7%）报告采用高水平消毒，而20名（20.6%）不清楚其工作场所采用的消毒级别。29名受访者（29.9%）实施基于拭子和培养的无菌保证，而41名（42.3%）报告未进行无菌检测。72名受访者（74.3%）报告再处理后储存不当，68家机构（70.1%）缺乏定期审计。书面方案的可用性与高水平消毒实践显著相关（P = 0.002）。指南熟悉程度与无菌检测相关（P < 0.001），专业角色与检查频率相关（P = 0.031）。
结论： 在喉镜片再处理方面观察到显著差距，尤其是在高水平消毒、无菌验证、储存和审计系统方面。书面方案、反复动手培训、客观监测和结构化使用前检查可提高依从性和患者安全。

英文摘要

BACKGROUND: Reusable laryngoscope blades are exposed to oropharyngeal secretions, blood, and mucosal surfaces during airway procedures. Incomplete reprocessing can make them a preventable source of cross-contamination. This survey assessed current practices related to cleaning, disinfection, sterilization, storage, and monitoring of laryngoscope blades in Indian healthcare facilities.
MATERIALS AND METHODS: This cross-sectional survey was conducted in January 2026 among 97 healthcare professionals involved in airway management or laryngoscope handling. Data were collected using a structured 20-item questionnaire through online forms and direct interviews. Responses were analyzed using descriptive statistics. Associations between selected practice-related variables were assessed using the Chi-square test, with P < 0.05 considered statistically significant.
RESULTS: Reusable laryngoscopes were reported by 96 respondents (99.0%). A written disinfection protocol was available in 59 facilities (60.8%). High-level disinfection was reported by 23 respondents (23.7%), whereas 20 (20.6%) were unaware of the disinfection level followed at their workplace. Swab and culture-based sterility assurance was practiced by 29 respondents (29.9%), whereas 41 (42.3%) reported no sterility testing. Inadequate postreprocessing storage was reported by 72 respondents (74.3%), and regular audit was absent in 68 facilities (70.1%). Written protocol availability was significantly associated with high-level disinfection practice (P = 0.002). Guideline familiarity was associated with sterility testing (P < 0.001), and professional role was associated with inspection frequency (P = 0.031).
CONCLUSION: Significant gaps were observed in laryngoscope blade reprocessing, particularly in high-level disinfection, sterility verification, storage, and audit systems. Written protocols, repeated hands-on training, objective monitoring, and structured preuse inspection can improve compliance and patient safety.
