To measure actual and instructed preoperative fasting durations in women undergoing scheduled cesarean birth, to compare these times with national guidelines for healthy patients undergoing elective procedures, and to describe discomforts associated with preoperative fasting.
One group, nonexperimental, comparative, descriptive.
Nonprofit private medical center in Texas with 6,000 births/year.
Convenience sample of 51 hospitalized postpartum women.
Participants were interviewed an average of 44 hours after their cesarean birth, and their medical records were reviewed for fasting information.
Duration of actual and instructed fasting, comparison with national guidelines, and ratings of thirst and hunger.
The participants fasted from liquids and solids an average of 11 and 13 hours, respectively. Both actual and instructed fasting durations were significantly longer than national guidelines. Most participants (70%) were instructed to be nulla per os after midnight whether they were to have a.m. or p.m. surgery. Thirst and hunger scores averaged 5 and 4, respectively, on a 0-10 scale.
Patients having scheduled cesarean birth fast for unnecessarily long periods. Nurses should be knowledgeable about evidence-based preoperative fasting practices and collaborate with physicians to implement them.
测量计划剖宫产的女性实际和医嘱的术前禁食时长，将这些时长与健康患者接受择期手术的国家指南进行比较，并描述与术前禁食相关的不适。
单组、非实验性、比较性、描述性研究。
德克萨斯州一家每年有6000例分娩的非营利性私立医疗中心。
51名住院产后女性的便利样本。
参与者在剖宫产术后平均44小时接受访谈，并查阅其病历以获取禁食信息。
实际和医嘱的禁食时长、与国家指南的比较以及口渴和饥饿评分。
参与者液体和固体食物的禁食时间分别平均为11小时和13小时。实际和医嘱的禁食时长均显著长于国家指南。大多数参与者（70%）无论上午还是下午手术，均被要求午夜后禁食。口渴和饥饿评分在0至10分的量表上分别平均为5分和4分。
计划剖宫产的患者禁食时间过长。护士应了解基于证据的术前禁食做法，并与医生合作实施这些做法。
