UK: The Association of Anaesthetists has released an updated guideline (update to 2011 guideline) on the peri‐operative management of people with hip fracture. No air? Uncertainty remains for trauma patients, whereas obstetric patients are considered to have a full stomach. However, the risk and consequences for fluid aspiration are very low, and the benefits of a more liberal approach might outweigh the strict adherence to the 6–4–2 rule even if that rule meant that a 2 h drink was given. • If a patient appears likely to fast for much longer than these times, please contact the anaesthetist (see below). Given that the rate of aspiration in elective patients is low, it is not surprising that Van de Putte and his colleagues16 did not report any such instances in this study.

The quantity and composition of this is subject to individual variation depending on many, often non-quantifiable variables. Although advised fasting times for solids remain unchanged, there is good evidence to support a 1-h fast for children, with no increase in risk of pulmonary aspiration. There will always be fluids or gastric secretions present. Read now. It is widely recognised that prolonged fasting for elective surgery in both children and adults serves no purpose, adversely affects patient well-being and can be detrimental. The general practitioner has a major role to play by ensuring that patients are... Gustafsson UO et al. A sizeable amount of juice (7 ml kg−1) administered to children is all but gone from the stomach within 1 h of ingestion as judged by magnetic resonance imaging.11 Solids, however, behave differently, both in the speed with which they leave the stomach and in their ability to cause harm on aspiration.1 12 What is relevant to the practice of anaesthesia is the presence and quantity of solid, particulate matter in the stomach, not fluids. 1 BACKGROUND.

There will be anaesthetists who have acquired more advanced competencies, thus allowing provision of a more extensive anaesthetic service, and those competencies should be maintained. Indeed, it is not surprising that many of these children may have been thirsty because children of both arms of the study had been fasted for fluid for more than 11 h before surgery.

It is essential to appreciate that the often quoted and extrapolated work of Roberts and Shirley17 in this regard relates to anecdotal data obtained from a single rhesus monkey. What is potentially alarming is the relatively high rate (1.7%) of solid material present. Early oral feeding is the preferred mode of nutrition for surgical patients. Liquid aspiration occurs during normal sleep in almost half of the population and up to 70% of patients with depressed consciousness.10 This does not usually result in significant clinical consequences, such as pneumonia or hospital admission. What remains to be shown is whether the 1.5 ml kg−1 residual volume represents a significant clinical risk let alone the ‘full stomach’ as described. Published by Renal Association, 01 March 2015. Showing results 1 to 10.

Children <3 yr old whose preoperative fasting time is minimized by active measures show less reduction in blood pressure on induction and less evidence of a catabolic state.13 Most strikingly, these changes are seen with a very modest reduction in mean fasting time from 8.5 to 6 h. Reduction of the postoperative fasting time may also be of benefit according to the article published by Chauvin and colleagues14 in this edition of the BJA. In expert hands, it seems that the gastric volume can be assessed by ultrasound, although it is unclear whether the inter-observer variability of this technique is suitable for this to become a ‘core’ anaesthetic skill. Even the most diligent published attempts to reduce the preoperative fluid fast whilst adhering to a 2 h rule have failed to lower it, in practice, much below 6 h, and it seems that Chauvin and colleagues14 have the same issue.

It is natural that anaesthetists fear the risk of pulmonary aspiration of gastric content under their direct clinical care. That early work described the catastrophic consequences of particulate matter aspiration but also reported all those who aspirated non-particulate matter (40 patients out of 44 016) survived. Despite all this, the resultant mean fast was reported to be 1.7 h, and no patient came to theatre in less than half an hour after a drink. The UK's new Covid cases and deaths have fallen again, with 397 more people dying and 15,539 testing positive. On the contrary, the shortened fasting times improved the perioperative experience for parents and children.

Those children reaching recovery with a high pain score and offered a drink of dilute apple juice in preference to an initial rescue dose of morphine showed a reduction in the pain score, less postoperative vomiting, a shorter recovery stay, and less postoperative rescue opioid ultimately. Anaesthesia textbooks are full of recommended techniques to reduce the perceived risk of pulmonary aspiration, ranging from rapid sequence induction with cricoid pressure to the pharmacological modification of gastric pH using H2-receptor blockers, proton-pump inhibitors, antacids, or prokinetics.

Being able to identify these patients and those with extremely high liquid residual volumes would be more of a reassurance rather than help in guiding perioperative management.

The objective is to minimize the risk of pulmonary aspiration of gastric contents, but also to prevent unnecessarily long fasting intervals. Several paediatric centres in the UK have started to allow selected low-risk children a clear fluid drink on arrival in the admission unit up to an hour before anaesthesia in recognition of the suffering and distress that a prolonged fast can cause.
