Disturbances of acid-base equilibrium occur in a wide variety of critical illnesses and are among the most commonly encountered disorders in the intensive care unit (ICU). In addition to reflecting the seriousness of the underlying disease, disturbances in hydrogen ion concentration ([H+]) have important physiologic effects.

The 2 major differentials for elevated body temperature (> 102.5 F) are fever (pyrexia) and hyperthermia. Hyperthermia results from increased muscle activity, increased environmental temperature, or increased metabolic rate (i.e. hyperthyroidism). Fever develops when the thermoregulatory set point in the hypothalamus is increased, resulting in increased body temperature from physiologic mechanisms inducing endogenous heat production or heat conservation.

Vomiting is one of the most common medical presentations to the emergency room. It is not uncommon for the dog or cat to eat grass or their food and vomit – and subsequently go about their lives unaffected. So – when is vomiting an emergency? While there are no simple, nor clear cut answers, the simple guidelines in the box can guide the triage nurse or doctor.

Cytology is a relatively easy, relatively non-invasive, fast and inexpensive diagnostic technique. Sometimes you actually get the diagnosis. Other times you don't get a specific diagnosis, but the cytologic findings can help you decide which diagnostic technique might be indicated as a next step. Also some potential diagnoses often can be ruled out.

The term adverse drug reaction includes any undesired effect of a drug, including a lack of the desired effect. Adverse reactions to veterinary drugs can range from minor to severe and life-threatening.

The success of any fixed dosing regimen most often is based on the patient's clinical response to the drug. Fixed dosing regimens are designed to generate plasma drug concentrations (PDC) within a therapeutic range, ie, achieve the desired effect while avoiding toxicity.

Most chronic vomiting and chronic diarrhea in cats originate in the small bowel.

The veterinary practitioner may be involved in some cases where pain management with NSAIDs or opioids is not possible due to the unacceptable risk of adverse effects.

Abdominal hemorrhage can result from disruption of a "blood" organ such as the liver or spleen, damage or avulsion of an abdominal artery or vein, or coagulation defect. The presence of blood in the abdomen can result in acute and severe pain from the abdominal cavity, abdominal organs or the nerves, muscles, fascia or skin associated with the abdomen.

Lumps and bumps that are cutaneous or subcutaneous often lend themselves very well to cytologic evaluation. They are easy to get to and most animals don't require sedation or anesthesia for you to obtain these samples. Although a definitively diagnostic sample isn't always obtained, the investment of time and equipment is minimal, and may give you the answer quickly and inexpensively.

Many of the reproductive abnormalities that present as emergencies are straight-forward and relatively easy to resolve. Treatment of these diseases, however, requires knowledge of the underlying pathophysiology as well as the options available for dealing with such emergencies.

Individualized drug therapy increasingly is being recognized as an important aspect of health care for both human and veterinary medicine. Consequently, veterinarians must reach beyond FDA-approved veterinary products to provide the current standard of veterinary care to their patients.
