Abstract
PURPOSE To evaluate the effect of post-surgical photobiomodulation therapy in dogs. METHODS Twenty dogs were selected for elective gastropexy and randomly divided into a control (CG, n = 10) and a PBMT group (PBMTG, n = 10). Pre‑medication consisted of medetomidine and butorphanol. Meloxicam was administered before the procedure. Induction was performed with propofol and maintained with sevoflurane. Local blocks with lidocaine were used. Incisional gastropexy was performed in all animals. PBMTG received PBMT immediately after surgery. The need for postoperative rescue analgesia, if the animal had eaten by the evaluation momen, and pain scores were collected using the Glasgow Composite Measure Pain Scale - Short Form (CMPS‑SF) at 1, 2, 4, 6, 8, 12, 16, 20, and 24 h post‑endotracheal extubation. CMPS‑SF scores were compared with the Mann-Whitney Test and proportions of animals that required rescue analgesia and had eaten with a χ2 test. P was set at < 0.05. RESULTS No rescue analgesia was needed for any animal. Still, significant differences were observed in CMPS-SF scores between CG and PBMTG between 1 and 4 h post-extubation. PBMTG had a significantly higher proportion of animals eating up to the 8 h post-extubation evaluation moment. CONCLUSION Adding post-surgical photobiomodulation to a standard anesthesia and analgesia protocol reduced CMPS-SF scores and increased the proportion of animals that resumed eating compared to the standard protocol alone.

Abstract
OBJECTIVE To determine if clinician experience influenced the euthanasia rate in 2 common surgical emergencies. ANIMALS 142 dogs with nontraumatic hemoabdomen (NTH) due to suspected ruptured splenic mass and 99 dogs with gastric dilatation-volvulus (GDV) where the owner either elected surgery or euthanasia. PROCEDURES Medical records were reviewed for dogs that had either NTH or GDV. For each patient, the owner's decision to pursue euthanasia versus surgery was recorded. The primary clinician was categorized as an intern, defined as a clinician with < 12 months experience, or a non-intern, defined as a clinician with more than 12 months experience. The euthanasia rates were compared used a Fisher exact, and the 95% CI was calculated for the risk of euthanasia if the primary clinician was an intern compared with a non-intern. If a difference was identified, subgroups comparing time of day, referral status, age, Hct, total solids, lactate, and heart rate were evaluated using a t test with a Bonferroni correction for the continuous variables and a Fisher exact for categorical variables. RESULTS For dogs with NTH, the euthanasia rate for cases primarily managed by non-interns (52%) was significantly lower than that of interns (76%; P = .005). The relative risk of euthanasia associated with NTH when the case was treated by an intern was 1.44 with a 95% CI of 1.1229 to 1.8567. For 99 dogs with GDV, the rate of euthanasia was not different between interns and non-interns. CLINICAL RELEVANCE The euthanasia rate for dogs with NTH may be impacted by the level of experience of the clinician. Support of new clinicians during challenging conversations should be provided.

Abstract
Protein C activity, a novel prognostic marker, was evaluated in patients with gastric dilatation and volvulus in relation to mortality and severity of the disease. Data on the mortality, duration of clinical signs, degree of gastric torsion, gastric necrosis, splenectomy and occurrence of disseminated intravascular coagulopathy were recorded. Blood samples were obtained at selected time periods: T0 = no longer than 30 min before surgery; T1 = first day after surgery; T2 = second day after surgery. In addition to protein C activity assessment, haematological and haemostaseological analysis was also performed. The mean protein C activity was the lowest at T1 and the highest at T2. No significant relationship between protein C activity and mortality, duration of clinical signs, degree of gastric torsion, gastric necrosis, splenectomy and disseminated intravascular coagulopathy was found in patients with gastric dilatation and volvulus. All patients that died during hospitalisation after surgery were patients with decreased protein C activity at T1. Although protein C activity was not found to be a reliable preoperative prognostic marker in patients with gastric dilatation and volvulus, the study results show it might be a promising marker in postoperative monitoring of these patients.

Abstract
OBJECTIVE To compare the outcomes of dogs surgically treated for gastric dilatation volvulus (GDV) after rapid versus prolonged medical stabilization. STUDY DESIGN Prospective cohort study, monoinstitutional. SAMPLE POPULATION One hundred and sixty-two dogs with GDV. METHODS Dogs presenting with a GDV were allocated to 1 of 2 groups, immediate or delayed. In the immediate group, dogs were stabilized for 90 min prior to undergoing surgery. In the delayed group, dogs underwent surgery after at least 5 h of stabilization. Medical stabilization included gastric decompression and placement of an indwelling nasogastric tube to prevent further gastric dilatation in all dogs. Short-term outcomes were compared between surgical timings by univariate and multivariate analyses. RESULTS Dogs (n = 89) in the immediate group underwent surgery a median time of 2.1 h after presentation (range 1.9-2.5 h), whereas those in the delayed surgery group (n = 73) were operated a median time of 9.8 h (range 5.4-13.7 h) after presentation. Survival rates did not differ between dogs undergoing immediate or delayed surgery at discharge (70/89 and 60/73, respectively) or at 1 month postoperatively (68/89 and 55/73, respectively). The degree of gastric torsion was differently distributed between the 2 groups (P = .05). In the immediate group, 19, 52, and 9 dogs had a 0°, 180° and 270° gastric torsion respectively, whereas in the delayed group, 27, 32, and 5 dogs had a 0°, 180° and 270° gastric torsion respectively. Hyperlactatemia 24 h after initiation of fluid therapy was associated with an increased in-hospital mortality risk and at 1 month postoperatively. CONCLUSION No survival benefit was detected as a result of proceeding to surgery after either a rapid or a prolonged medical stabilization. CLINICAL SIGNIFICANCE The aggressive stabilization and monitoring protocol described here can be considered as an alternative to stabilize dogs with GDV prior to surgery within 13.7 h of presentation. Further research is required to investigate the potential risks and benefits of prolonged over rapid stabilization and to identify candidates for each approach.

Abstract
Emergency abdominal surgery carries high morbidity and mortality rates in human medicine; however, there is less evidence characterising the outcome of these surgeries as a single group in dogs. The aim of the study was to characterise the clinical course, associated complications and outcome of dogs undergoing emergency abdominal surgery. A retrospective study was conducted. Dogs undergoing emergency laparotomy were included in the study. Logistic regression analysis was performed to identify variables correlated with death and complications. Eighty-two dogs were included in the study. The most common reason for surgery was a gastrointestinal foreign body. Overall, the 15-day mortality rate was 20.7% (17/82). The median (range) length of hospitalisation was 3 (0.5-15) days. Of the 82 patients, 24 (29.3%) developed major complications and 66 (80.5%) developed minor complications. Perioperative factors significantly associated with death included tachycardia (p < 0.001), hypothermia (p < 0.001), lactate acidosis (p < 0.001), shock index > 1 (p < 0.001), leukopenia (p < 0.001) and thrombocytopenia (p < 0.001) at admission, as well as intraoperative hypotension (p < 0.001) and perioperative use of blood products (p < 0.001). The results of this study suggest that mortality and morbidity rates after emergency abdominal surgery in dogs are high.

Pet health insurance reduces the likelihood of pre-surgical euthanasia of dogs with gastric dilatation-volvulus in the emergency room of an Australian referral hospital. N Z Vet J 2021; 69:267-273.

Abstract
AIMS To determine the association between the presence of pet health insurance and the risk of euthanasia at the time of diagnosis for dogs with gastric dilatation-volvulus (GDV). METHODS Insurance status at the time of GDV diagnosis was sought for a cohort of 147 non-referred, confirmed cases of GDV that presented to the emergency department of a university-based veterinary hospital in Australia between 2008 and 2017. Insurance status was obtained from the medical record (n=18) or after contacting the owners by phone using a standardised questionnaire (n=129). Animal, clinical and outcome data was retrospectively compiled in a research database. The primary outcome measure was whether or not the dog was euthanised before surgery. The Mantel-Haenszel procedure was used to quantify the association between the presence of pet health insurance and the risk of euthanasia at the time of diagnosis for dogs with GDV, adjusting for the confounding effect of age at the time of presentation using Bayesian methods. RESULTS Of the 69 dogs for which insurance information could be obtained, 10 (14%) cases were insured at the time of the GDV event and 59 (86%) cases were not. The majority of non-insured dogs (37/59; 63 (95% CI=50-74)%) were euthanised before surgery, while none (0 (95% CI=0-28)%) of the insured dogs were euthanised at that time (p<0.001). Of the 32 insured and non-insured dogs that underwent surgery, four dogs (13 (95% CI=5-28)%) did not survive to hospital discharge. Three dogs (9%) were euthanised during or after surgery and one dog (3%) experienced cardiopulmonary arrest during treatment. The majority of dogs for which insurance status was known did not survive to hospital discharge (41/69; 59%), and 90 (95% CI=7-96)% of deaths were caused by euthanasia prior to surgery. Uninsured dogs were 5.0 (95% credible interval=1.8-26) times more likely to undergo presurgical euthanasia compared with insured dogs. CONCLUSIONS Euthanasia prior to treatment was most common cause of death in non-referred dogs with GDV; such euthanasia was entirely absent in the cohort of dogs that were insured. CLINICAL RELEVANCE Financial considerations significantly contribute to mortality of dogs with GDV presented to an emergency room. Financial instruments to reduce the out-of-pocket expense for pet owners confronted with unexpected veterinary expenses have potential to reduce pet mortality.

The Effect of Pet Insurance on Presurgical Euthanasia of Dogs With Gastric Dilatation-Volvulus: A Novel Approach to Quantifying Economic Euthanasia in Veterinary Emergency Medicine. Front Vet Sci 2020; 7:590615. [PMID: 33364255 PMCID: PMC7752994 DOI: 10.3389/fvets.2020.590615] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Accepted: 11/12/2020] [Indexed: 11/14/2022] Open
Abstract
Euthanasia of companion animals in veterinary emergency medicine is a common cause of death. Euthanasia is economic when it is the consequence of the pet owner's inability to afford essential treatment while a viable medical alternative to euthanasia exists. Gastric dilatation-volvulus (GDV) is an acute life-threatening emergency condition of dogs; if left untreated, rapid death is highly likely. Surgical treatment leads to survival of around 80-90% of dogs; however, such treatment is costly. Therefore, pre-surgical euthanasia may be largely economically motivated. Having pet insurance, a financial instrument to reduce the burden of unforeseen veterinary medical costs on pet owners, would be expected to abolish the risk for pre-surgical economic euthanasia. We therefore aimed to determine whether pet insurance attenuates the risk of pre-surgical economic euthanasia in dogs with GDV. Non-referred dogs (n = 260) with GDV and known insurance status seen at 24 emergency clinics over a 2-year period were included. Relevant data (e.g., insurance status, age, comorbidities, outcome) were retrospectively extracted from a pet insurer's claim records (insured animals) or from electronic medical records of participating hospitals (non-insured animals). Forty-one percent of dogs (106 of 260 dogs) did not survive to hospital discharge; 82 (77%) of non-survivors died before surgery, all through euthanasia. The pre-surgical euthanasia rate was 10% in insured and 37% in non-insured dogs (p < 0.001). When adjusted for the effect of age, deposit size, comorbidities, and blood lactate concentration, the absence of insurance increased the odds of pre-surgical euthanasia by a factor of 7.4 (95% CI 2.0 to 37; p = 0.002). Of dogs undergoing surgery, 86% survived to hospital discharge. Overall, 80% of insured animals and 53% of non-insured animals survived to hospital discharge (p < 0.001). Thus, insurance was associated with a marked decrease in risk of pre-surgical euthanasia indicating that the cause of pre-surgical euthanasia of dogs with GDV is predominantly economic in nature. The rate of pre-surgical euthanasia in dogs with GDV may emerge as a suitable marker to quantify economic decision making of pet owners and to measure the impact of financial interventions aimed at mitigating economic duress associated with cost of veterinary emergency care.
