Role of pulmonary intravascular macrophages in endotoxin-induced lung inflammation and mortality in a rat model

Role of pulmonary intravascular macrophages in endotoxin-induced lung inflammation and mortality in a rat model

Bile-duct ligated (BDL) rats recruit pulmonary intravascular macrophages (PIMs) and are highly susceptible to endotoxin-induced mortality. The mechanisms of this enhanced susceptibility and mortality in BDL rats, which are used as a model of hepato-pulmonary syndrome, remain unknown. We tested a hypothesis that recruited PIMs promote endotoxin-induced mortality in a rat model.

Rats were subjected to BDL to induce PIM recruitment followed by treatment with gadolinium chloride (GC) to deplete PIMs. Normal and BDL rats were treated intravenously with E. coli lipopolysaccharide (LPS) with or without GC pre-treatment followed by collection and analyses of lungs for histopathology, electron microscopy and cytokine quantification.

BDL rats recruited PIMs without any change in the expression of IL-1β, TNF-α and IL-10. GC caused reduction in PIMs at 48 hours post-treatment (P < 0.05). BDL rats treated intravenously with E. coli LPS died within 3 hours of the challenge while the normal LPS-treated rats were euthanized at 6 hours after the LPS treatment. GC treatment of rats 6 hours or 48 hours before LPS challenge resulted in 80% (1/5) and 100% (0/5) survival, respectively, at 6 hours post-LPS treatment. Lungs from BDL+LPS rats showed large areas of perivascular hemorrhages compared to those pre-treated with GC. Concentrations of IL-1β, TNF-α and IL-10 were increased in lungs of BDL+LPS rats compared to BDL rats treated with GC 48 hours but not 6 hours before LPS (P < 0.05).

We conclude that PIMs increase susceptibility for LPS-induced lung injury and mortality in this model, which is blocked by a reduction in their numbers or their inactivation.

A Review of the Surgical Management of Perineal Hernias in Dogs

A Review of the Surgical Management of Perineal Hernias in Dogs

Abstract: Perineal hernia refers to the failure of the muscular pelvic diaphragm to support the rectal wall, resulting in herniation of pelvic and, occasionally, abdominal viscera into the subcutaneous perineal region. The proposed causes of pelvic diaphragm weakness include tenesmus associated with chronic prostatic disease or constipation, myopathy, rectal abnormalities, and gonadal hormonal imbalances. The most common presentation of perineal hernia in dogs is a unilateral or bilateral nonpainful swelling of the perineum. Clinical signs do occur, but not always. Clinical signs may include constipation, obstipation, dyschezia, tenesmus, rectal prolapse, stranguria, or anuria. The definitive diagnosis of perineal hernia is based on clinical signs and findings of weak pelvic diaphragm musculature during a digital rectal examination. In dogs, perineal hernias are mostly treated by surgical intervention. Appositional herniorrhaphy is sometimes difficult to perform as the levator ani and coccygeus muscles are atrophied and unsuitable for use. Internal obturator muscle transposition is the most commonly used technique. Additional techniques include superficial gluteal and semitendinosus muscle transposition, in addition to the use of synthetic implants and biomaterials. Pexy techniques may be used to prevent rectal prolapse and bladder and prostate gland displacement. Postoperative care involves analgesics, antibiotics, a low-residue diet, and stool softeners.

Factors associated with dehiscence and mortality rates following gastrointestinal surgery in dogs

Factors associated with dehiscence and mortality rates following gastrointestinal surgery in dogs

To identify factors associated with dehiscence and mortality rates following gastrointestinal surgery in dogs.

170 client-owned dogs that underwent gastrointestinal surgery from 2010 to 2016.

Medical records of all included dogs were reviewed to collect information on preoperative (breed, sex, age, body weight, American Society of Anesthesiologists [ASA] physical status classification, emergency status, and plasma lactate concentration), intraoperative (indication for surgery, type of surgery, and whether bacterial peritonitis was identified), and postoperative (development of dehiscence and survival status at 2 weeks after surgery) factors. Preoperative and intraoperative factors were evaluated for associations among each other and with postoperative factors.

Univariate analyses revealed that preoperative plasma lactate concentration increased with increasing ASA status, and lactate concentrations were significantly higher for nonsurvivors (mean ± SD, 4.6 ± 3.7 mmol/L) than for survivors (2.4 ± 1.7 mmol/L). Multivariate analysis controlling for age, body weight, and plasma lactate concentration revealed that dogs with an ASA status ≥ 3 were more likely to develop dehiscence after gastrointestinal surgery than were dogs with a lower ASA status (OR, 17.77; 95% confidence interval, 2.17 to 144.06). Multivariate analysis also revealed that dogs with an ASA status ≥ 3 or high lactate concentration were less likely to survive than were other dogs.

Conclusions and Clinical Relevance
These findings regarding ASA status and preoperative plasma lactate concentration and their associations with outcome may help clinicians to determine and provide optimal perioperative care to dogs requiring gastrointestinal surgery as well as to inform owners about prognosis.

VCA Canada 404 Veterinary Emergency and Referral Hospital is proud to offer a full-service surgery department. We can provide care for the most challenging surgical cases including: orthopedic, thoracic, spinal, gastrointestinal, oncologic, ear, nose and throat, and reconstructive surgery. We take pride in providing these services on short notice and to animals in critical condition. Our surgical team is available to care for your pet day or night, including weekends and holidays.

In addition to obtaining their general veterinary degrees, all of the surgeons at the 404 have completed (at minimum) a 1-year surgical internship and a 3-year surgical residency to become eligible to sit the rigorous board examinations from the American College of Veterinary Surgeons (ACVS). In addition to ACVS board-certified surgeons, our surgery team includes anesthesiologists, highly trained registered veterinary technicians/ technologists, and surgical assistance support staff. We believe that a “successful” surgical case requires attention to detail at every stage of case management from every member of our team.

Our approach to surgical consultation includes:

  • Initial consultation with the surgeon and a review of the surgical techniques required, any potential complications, and anticipated outcomes and costs;
  • Accurate diagnosis using appropriate tests such as on-site blood tests, radiographs, computerized tomography (CT), arthroscopy, laparoscopy biopsy, etc;
  • Supervised anesthesia to ensure smooth induction and recovery with intensive intra-operative monitoring under the direct supervision of our experienced veterinary technicians;
  • Pre and postoperative pain management. We believe in pre-emptive and multimodal pain management;
  • Surgical procedure ensuring careful attention to aseptic technique. Our surgeons have a broad range of training and experience in a wide variety of surgical techniques;
  • 24-hour after-care to ensure appropriate pain management and postoperative management techniques are applied through the night and over the weekend;
  • Comprehensive home-care instructions upon discharge. A discharge appointment is set up to ensure that all go-home instructions are reviewed and understood. All care instructions are written down and accompany the pet parent in a discharge package;
  • Postoperative follow-up appointment booking. We like to see our cases through to successful conclusions whenever possible. Suture removal and other follow-up appointments are scheduled at the time of discharge; and
  • Finally, a day or two after being discharged, our team will make a follow-up call to ensure home recovery is going smoothly and to answer any questions or concerns if they arise.
