RESUMEN

Severe acute respiratory syndrome coronavirus 2 (SARSCov- 2) is hypothesized to have originated from a spillover event from an animal reservoir. This has raised many questions, with an important one being whether the widely disseminated coronavirus disease 2019 (COVID-19) is transmissible to other animal species. SARS-CoV-2 is primarily transmitted person to person. K9-to-human transmission, although theoretically possible via fomites, is considered minimal, if at all, and there have been no reported cases of K9-to-human transmission. Human-to-K9 transmission, although rare, seems more likely; however, in only one case has a K9 been suspected to have displayed symptoms of COVID-19. Preparation, decontamination, hand hygiene, and distancing remain the key factors in reducing transmission of the virus. The information presented is applicable to personnel operating within the military conventional and Special Operation Forces as well as civilian Tactical Emergency Medical Services communities who may have the responsibility of supporting an operational K9.

RESUMEN

First introduced in 1996, Tactical Combat Casualty Care (TCCC) redefined prehospital, point-of-injury (POI), battlefield trauma care for the human combat casualty. Today, many consider TCCC as one of the most influential interventions for reducing combat-related case fatality rates from preventable deaths in human combat casualties. Throughout history, Military Working Dogs (MWDs) have proved and continue to prove themselves as force multipliers in the success of many military operations. Since the start of the Global War on Terror in 2001, these elite canine operators have experienced an upsurge in combat-related deployments, placing them at a higher risk for combat-related injuries. Until recently, consensus- based Canine-TCCC (K9TCCC) guidelines for POI battlefield trauma care did not exist for the MWD, leaving a critical knowledge gap significantly jeopardizing MWD survival. In 2019, the Canine Combat Casualty Care Committee was formed as an affiliate of the Committee on Tactical Combat Casualty Care with the intent of developing evidence- based, best practice K9TCCC guidelines. Modeled after the same principles of the human TCCC, K9TCCC focuses on simple, evidence-based, field-proven medical interventions to eliminate preventable deaths and to improve MWD survival. Customized for the battlefield, K9TCCC uniquely adapts the techniques of TCCC to compensate for canine-specific anatomic and physiological differences.

RESUMEN

Similar to people, airway obstruction is a potentially preventable cause of combat and line of duty death for civilian law enforcement Operational K9s (OpK9) and military working dogs (MWD). Basic (i.e., body positioning, manual maneuvers, bag-valve-mask ventilation) and advanced (i.e., endotracheal intubation, surgical airways) airway techniques are designed to establish a patent airway, oxygenate and ventilate, and protect from aspiration. A surgical airway (cricothyrotomy [CTT] or tracheostomy [TT]) is warranted for difficult airway scenarios in which less invasive means fail to open an airway (aka "Cannot intubate, cannot oxygenate"). In people, the surgical CTT is the preferred surgical airway procedure; most human prehospital providers are not even trained on the TT. Currently, only the TT is described in the veterinary literature as an emergent surgical airway for MWDs. This article describes the novel approach of instituting the surgical CTT for managing the canine difficult airway. The information provided is applicable to personnel operating within the US Special Operations Command as well as civilian tactical emergency medical services that may have the responsibility of providing medical care to an OpK9 or MWD.

RESUMEN

Major trauma often involves varying degrees of hemorrhage. Left unattended, any amount of trauma-induced hemorrhage may rapidly become life threatening. Similar to humans, Operational canines (OpK9s) can suffer penetrating trauma and blunt trauma that lead to compressible and noncompressible hemorrhage. Preserving organ function and saving the life of a massively bleeding OpK9 require the implementation of immediate and effective hemostatic measures. Effective hemorrhage control interventions for the exsanguinating OpK9 are similar to those for humans: direct pressure, wound packing, hemostatic agents and devices, pressure bandage, and, possibly, tourniquet application. Although tourniquet application is a life-saving intervention in humans experiencing extremity hemorrhage, it is not considered a necessary, immediate-action life-saving intervention for canines with extremity injuries. This article provides a brief description of the basic methods for identifying life-threatening hemorrhage and achieving immediate hemostasis in the bleeding OpK9 during the prehospital period.

RESUMEN

Pyotraumatic dermatitis (a.k.a., hot spot) is a rapidly developing, superficial, moist, exudative dermatitis commonly induced by self-inflicted trauma. Although not acutely life threatening, these lesions are extremely pruritic and distracting and significantly interfere with the canine's operational effectiveness and ability to stay on task. The review discusses a case, including clinical presentation, diagnosis, treatment, and prognosis.

RESUMEN

The intent of the Operational K9 (OpK9) ongoing series is to provide the Special Operations Medical Association community with clinical concepts and scientific information on preventive and prehospital emergency care relevant to the OpK9. Often the only medical support immediately available for an injured or ill OpK9 in the field is their handler or the human Special Operations Combat Medic or civilian tactical medic attached to the team (e.g., Pararescueman, 18D, SWAT medic). The information is applicable to personnel operating within the US Special Operations Command as well as civilian Tactical Emergency Medical Services communities that may have the responsibility of supporting an OpK9.

RESUMEN

The increasing use of opioids (e.g., fentanyl, carfentanil) for illicit drug manufacturing poses a potential life-threatening hazard to law enforcement officers and first responders (e.g., EMS, fire and rescue) who may unknowingly come into contact with these drugs during the course of their daily activities. Similarly, Operational canines (OpK9s) of all disciplines-detection (drug, explosive, accelerant), patrol, tracking, search and rescue, and others-are at risk for accidental illicit opioid exposure. The most serious adverse effect of opioid exposure is respiratory depression leading to slow, shallow breathing or complete cessation of voluntary breathing (respiratory arrest). Naloxone, an opioid antagonist, is the antidote for reversing the effects of an opioid overdose in both humans and OpK9s. This clinical update describes the potential risks associated with opioid exposure as well as the use of naloxone as it pertains to the OpK9.

RESUMEN

OBJECTIVE To assess effects of major abdominal surgery on serum cortisol and aldosterone and plasma canine ACTH (cACTH) concentrations. ANIMALS 39 healthy dogs undergoing laparotomy during veterinary student surgical laboratories. PROCEDURES Blood samples were obtained before and at completion of surgery. Serum cortisol and aldosterone and plasma cACTH concentrations were measured by use of validated radioimmunoassays. Changes in concentrations (postoperative concentration minus preoperative concentration) were calculated. Data were analyzed by use of the Wilcoxon signed rank test, Pearson correlation analysis, and Mann-Whitney rank sum test. RESULTS Cortisol, aldosterone, and cACTH concentrations increased significantly from before to after surgery. Although cortisol and aldosterone concentrations increased in almost all dogs, cACTH concentrations decreased in 6 of 32 (19%) dogs. All dogs had preoperative cortisol concentrations within the reference range, but 24 of 39 (62%) dogs had postoperative concentrations above the reference range. A correlation between the change in cACTH concentration and the change in cortisol concentration was not detected. CONCLUSIONS AND CLINICAL RELEVANCE Laparotomy caused a significant increase in serum cortisol and aldosterone concentrations. In most dogs, but not all dogs, plasma cACTH concentrations increased. Lack of correlation between the change in cACTH concentration and the change in cortisol concentration suggested that increased postoperative cortisol concentrations may have been attributable to ACTH-independent mechanisms, an early ACTH increase that caused a sustained cortisol release, or decreased cortisol clearance. Further studies are indicated to evaluate the effects of various anesthetic protocols and minimally invasive surgical techniques on the stress response.

RESUMEN

BACKGROUND: Approximately 20% to 25% of trauma-related, prehospital fatalities in humans are due to preventable deaths. Data are lacking, however, on the nature and the prevalence of operational canine (OC) prehospital deaths. It is plausible that OCs engaged in high-threat operations are also at risk for suffering some type of preventable death. Tactical Combat Casualty Care has significantly reduced human fatality rates on the battlefield. Standardized guidelines specifically for prehospital trauma care have not been developed for the OC caregiver. An initiation has been approved by the Committee for Tactical Emergency Casualty Care to form a K9-Tactical Emergency Casualty Care (TECC) working group to develop such guidelines. SIGNIFICANCE: The intent of the K9-TECC initiative is to form best practice recommendations for the civilian high-risk OC caregiver. These recommendations are to focus on interventions that (1) eliminate the major causes of canine out-of-hospital preventable deaths, (2) are easily learned and applied by any civilian first responder, and (2) minimize resource consumption.
