“…Preoperative fasting has been applied before elective surgery to prevent the risk of aspiration of stomach contents during anesthesia [1] , but no study has examined whether there were negative effects of an HCD on the effects of duration of fasting and preoperative feeding on metabolic changes and anesthesia in children [3,4] . The ingestion of unlimited clear fluids by healthy 2-12-year-old children up to 2 h before elective surgery does not affect gastric contents [6] .…”

“…The routine use of perioperative oral dietary supplements in patients about to undergo gastrointestinal surgery confers no clinical or functional benefit [2] . However, this routine is now being questioned, because fasting causes discomfort and unnecessary problems with routine oral medication [3,4] . The free intake of water is allowed up to 3 h before surgery in children [5,6] and adults [7] .…”

“…The length of pre-operative fasting before anaesthesia has been a topic of debate for a long time, with many changes of policy, varying from the recommendation to take a light meal before anaesthesia [4], to the present guidelines of 4 h fluid deprivation and 6 h for solid food. Nasogastric tube aspiration, ultrasound imaging and transabdominal impedance have shown no significant difference in gastric volumes between patients fasted for 6 h and those allowed to drink water, coffee or fruit juice up to 3 h pre-operatively [5-91, even in post-partum women, a group traditionally considered at higher risk of acid aspiration [lo].…”

The effect of pre‐operative oral fluids on morbidity following anaesthesia for minor surgery

SummaryPostoperative morbidity and serum osmolality were studied in 46 patients who were encouraged to drink water until 3 h pre-operatively and 49 receising the normal fasting regimen prior to minor surgery. There was significantly less thirst in the postoperative period in those patients allowed to drink and subjectively better recovery than after previous anaesthesia. There was no morbidity from ingestion of up to I I of water 2.5h pre-operatively. Although there was only a moderate improvement in postoperative recovery we feel that allowing patients to drink water pre-operatively improves patient comfort, especially since patients may have to fast for much longer than guidelines recommend, simply because of the traditional organisation of operating lists.

“…[18][19][20][21] For juvenile and adult animals (ie, animals > 16 weeks old), food should be withheld for a minimum of 4 hours. [48][49][50][51][52] Although overnight fasting is acceptable, withholding food for > 6 hours is not necessary. 53 Exceptions to minimum fasting periods may be made for feral cats in traps because of the safety risks associated with removing uneaten bait.…”

As community efforts to reduce the overpopulation and euthanasia of unwanted and unowned cats and dogs have increased, many veterinarians have increasingly focused their clinical efforts on the provision of spay-neuter services. Because of the wide range of geographic and demographic needs, a wide variety of spay-neuter programs have been developed to increase delivery of services to targeted populations of animals, including stationary and mobile clinics, MASHstyle operations, shelter services, community cat programs, and services provided through private practitioners. In an effort to promote consistent, high-quality care across the broad range of these programs, the Association of Shelter Veterinarians convened a task force of veterinarians to develop veterinary medical care guidelines for spay-neuter programs. These guidelines consist of recommendations for general patient care and clinical procedures, preoperative care, anesthetic management, surgical procedures, postoperative care, and operations management. They were based on current principles of anesthesiology, critical care medicine, infection control, and surgical practice, as determined from published evidence and expert opinion. They represent acceptable practices that are attainable in spay-neuter programs regardless of location, facility, or type of program. The Association of Shelter Veterinarians envisions that these guidelines will be used by the profession to maintain consistent veterinary medical care in all settings where spay-neuter services are provided and to promote these services as a means of reducing sheltering and euthanasia of cats and dogs.
