This study examines the practice of pre-operative fasting in relation to fluids. Patients scheduled for elective surgery, and qualified nurses and anaesthetists were studied using a structured and semi-structured interview technique. Supporting the findings of previous studies, this study demonstrated that despite universal agreement between nurses and anaesthetists that patients routinely fast for longer than the recommended time for fluids, pre-operative fasting regimes are derived from routine practice. It was found that a single regime was used to encompass a range of operating times, leading to extended periods of fasting. These periods ranged from three and three quarter hours to 29 hours, with a mean and median fasting time of 11 hours. Fifty per cent of the anaesthetists in the study knew about recent research in this area of practice, but none of the nurses were aware of these recommendations. The absence of a hospital policy offering clear guidelines on the management of pre-operative fasting contributed to the prolonged periods for which patients were fasted. The study also highlighted the fact that patients receive insufficient information regarding the purpose and nature of their fast.
本研究探讨了与液体相关的术前禁食做法。采用结构化和半结构化访谈技术，对择期手术患者以及合格的护士和麻醉师进行了研究。支持先前研究的结果，本研究表明，尽管护士和麻醉师普遍一致认为患者常规禁食时间长于推荐的液体禁食时间，但术前禁食方案源自常规做法。研究发现，单一方案用于涵盖一系列手术时间，导致禁食时间延长。这些时间从三又四分之三小时到29小时不等，平均禁食时间和中位禁食时间为11小时。研究中50%的麻醉师了解该实践领域的近期研究，但没有护士知晓这些建议。缺乏关于术前禁食管理的明确指导方针的医院政策导致患者禁食时间延长。该研究还强调了患者未获得关于禁食目的和性质的足够信息这一事实。
