“…Propofol may have contributed to the higher incidence of GOR observed in our study compared to other studies that used thiopental as an induction agent [ 18 , 21 ]. Propofol, compared to thiopental, causes a more profound relaxation of the LOS [ 28 ], and a significantly higher incidence of GOR during anaesthesia in dogs [ 29 ].…”

This study aimed to investigate the effect of three different preoperative fasting regimens on the incidence of gastro-oesophageal reflux (GOR) in dogs under general anaesthesia. Ninety dogs undergoing non-abdominal and non-thoracic elective surgery were included in the study and equally allocated to three groups. Dogs received canned food providing half the daily resting energy requirements (RER) 3 h prior to premedication (group 3H), a quarter of the daily RER 3 h before premedication (group 3Q), and half the daily RER 12 h before premedication (group 12H). The animals were premedicated with acepromazine and pethidine, anaesthesia was induced with propofol and maintained with isoflurane vaporised in oxygen. Oesophageal pH was monitored throughout anaesthesia. Demographic and surgery-related parameters were not different among groups. The incidence of GOR was 11/30 in group 3H (36.7%), 9/30 in group 3Q (30.0%) and 5/30 in group 12H (16.7%), which was not statistically different (p = 0.262). Reduction of the amount of the preoperative meal from half to a quarter of the daily RER did not reduce the incidence of GOR but resulted in a lower oesophageal pH (p = 0.003). The results of this study suggest that the administration of a meal 3 h before anaesthesia does not have any beneficial effect in the reduction of GOR incidence in dogs compared to the administration of a meal 12 h before anaesthesia.

“…Reported incidences of GOR in the veterinary literature vary widely. With a fasting period of 3 h, the reported GOR episodes have been as low as 0 to 5% and as high as 61% [ 16 , 17 , 18 , 21 ]. In our study, the combined incidence of GOR in the two 3 h fasting groups together was 33.3% (20/60 dogs).…”

“…One report identified labrador retrieves, German shepherd dogs and crossbreeds as having a high incidence of regurgitation during anaesthesia (Lamata and others 2012), but it is not clear whether this was due to physio-logical or mechanical factors. As many of these breeds have deep chests (Fig 3), the cause may be mechanical (Anagnostou and others 2017). The size of the dog was also associated with regurgitation by Lamata and others (2012), suggesting that mechanical factors are as important as physiological predisposition.…”

“…Mechanical forces result from intra‐abdominal pressure relative to intrathoracic pressure, and are influenced by factors such as gut fill, body position, positional changes, and so on. As well as body shape and size making some breeds more prone to reflux (Anagnostou and others 2017), mechanical changes are caused by predisposing conditions such as obesity or pregnancy that increase abdominal fill and thus pressure relative to the thorax, facilitating reflux. Gastrointestinal (GI) disease, such as obstruction or ileus, can also reduce intestinal motility, leaving the stomach fuller.…”

Perioperative gastrointestinal reflux in dogs

Perioperative vomiting, regurgitation and reflux cause problems for veterinary patients during, but mostly after, anaesthesia. A history of gastrointestinal disease will often indicate the possibility of reflux, but many animals that regurgitate under anaesthesia have no previous history or predisposing factors, making this event an unwelcome surprise. If the refluxate fails to reach the larynx or mouth, the anaesthetist will be unaware and reflux will go untreated, with repeated incidents causing oesophagitis that can lead to stricture. Regurgitation complicates anaesthesia because animals have reduced or absent laryngeal reflexes and aspiration of refluxate leads to pneumonia. Following anaesthesia, irritation may make animals uncomfortable and less willing to eat, thus slowing their recovery and increasing any complications. This article aims to provide a greater depth of understanding as to why and how reflux occurs in anaesthetised dogs and what options are available for treatment.

“…Visceral motility disorders of the oesophagus, stomach and small and large intestines are commonly associated with critically ill patients and those undergoing sedation, general anaesthesia and operative procedures (Galatos & Raptopoulos 1995a, Galatos & Raptopoulos 1995b, De Miguel Garcia et al 2013, Whitehead et al 2016, Anagnostou et al 2017, Torrente et al 2017. Complications seen in patients with abnormal motility include aspiration pneumonia, oesophagitis and increased risk of bacterial translocation and sepsis, all of which are significant morbidities that can lead to increased length of hospital stay and treatment costs, and may result in patient mortality (Pearson et al 1978, Cotton & Smith 1984, Harai et al 1995, Leib et al 2001, Adamama-Moraitou et al 2002, Adami et al 2011, Whitehead et al 2016).…”

Objectives To quantify changes in gastric and intestinal emptying times in the conscious dog following gastrointestinal acupoint stimulation. Materials and Methods In a randomised, blinded crossover study, six dogs were fed 30×1.5 mm barium‐impregnated polyethylene spheres and underwent: (1) no acupuncture (Control); (2) stimulation of target points PC6 and ST36 (Target) and (3) stimulation of non‐target points LU7 and BL55 (Sham). Abdominal radiographs were assessed immediately after feeding the spheres and every hour for 12 hours and their number in the stomach and large intestines was counted. Results The number of barium‐impregnated polyethylene spheres found distal to the stomach was less in the Target group compared to the Control and Sham groups between hours 2 and 4, but no differences between groups were seen for the remainder of the treatment period. The number of spheres found within the colon/rectum was less in the Target group compared to the Control and Sham groups between hours 4 and 6, and compared to the Sham group only at hour 7 but no differences between groups were seen after hour 8. Clinical Significance Acupuncture targeted at the gastrointestinal tract of dogs was associated briefly with slowed gastric emptying and gastrointestinal transit time. This foundational study lays the groundwork for additional studies of acupuncture effects associated with altered physiologic states.
