“…Prolonged fasting (i.e. nil per os after midnight) has not been shown to lower the amount of gastric contents nor decrease gastric acidity (10,13,14). Perioperative fasting is associated with increased surgical stress, increased insulin resistance and impaired gastrointestinal function (6,7,15).…”

Objective: Prolonged preoperative fasting may lead to dehydration, hypoglycaemia, ketoacidosis and delayed recovery. We hypothesised that a patient educational initiative would decrease our preoperative fasting periods for elective caesarean delivery. Methods: This was an observational quality improvement impact study. Elective caesarean patients who delivered during our study period were included in the study, 40 patients in the pre-intervention and 40 patients in the post-intervention groups. Only English-speaking patients were included. We developed a patient educational pamphlet outlining preoperative fasting and analgesic expectations for caesarean delivery that was given to every patient at her preoperative anaesthesia consultation. The pamphlet included the American Society of Anesthesiologists' preoperative fasting and enhanced recovery carbohydrate drink recommendations. The primary outcome measure was intended fasting duration for liquids (defined as time from last reported liquid consumption to scheduled caesarean delivery) before and after the patient educational initiative. Secondary outcomes included solid fasting time, types of liquids and solids consumed. Results: The intended median (interquartile range) fasting time for liquids decreased from 10 (8.9-12) h to 3.5 (2.5-10) h (p<0.001). The fasting period for solids was not significantly different

“…Many published studies have reported no association between fasting duration and adverse events such as vomiting and pulmonary aspiration [16][17][18] . Schmitz and Ajuzieogu reported that gastric content volume did not correlate with fasting times in children and adolescents [19][20] . This evidence questions the necessity of pre-sedation fasting.…”

Background: Moderate and deep sedation are well-established techniques in many developed countries, and several guidelines have been published. However, they have received attention in China only in recent years. The aim of this study is to investigate current paediatric sedation practices in tertiary children’s hospitals and tertiary maternity and children hospitals in China. Methods: All tertiary children’s hospitals and tertiary maternity and children hospitals registered with the National Health Commission of the People’s Republic of China were invited to participate in an electronic survey, which included information on the sedation caseload, facility availability, staff structure, clinical-skill requirements for sedation providers, fasting guidelines, patient-monitoring practices, and choice of sedatives. Results: Fifty-eight of the 63 hospitals that completed the survey (92.1%) provided moderate and deep sedation. Dedicated sedation rooms and post-sedation recovery rooms were found in only 14 (24.1%) and 19 (32.8%) hospitals, respectively. Sedation for non-invasive procedures was primarily performed by anaesthesiologists (69.0%); however, 75.9% of the sedation providers had not received paediatric basic and advanced life-support training. Children were asked to fast from clear liquids for at least 2 h in 44.8% of hospitals and at most 6 h in 5.2% of hospitals; they were asked to fast from solid food/milk for at least 4 h in 27.6% of hospitals and more than 8 h in 1.7% of hospitals. The most commonly used sedative in all groups was chloral hydrate. For rescue, propofol was the most widely used sedative, particularly for children older than 4 years. Conclusion: Moderate and deep sedation practices vary widely in tertiary children’s hospitals and tertiary maternity and children hospitals in China. More optimized practices should be established to improve the quality of moderate and deep sedation.
