91

When are SQ fluids contraindicated?

If animals require large replacement volumes, hypothermic patients, or severely dehydrated

92

Where are SQ fluids administered?

Where loose connective tissue is abundant

SQ space over dorsal neck, and cranial trunk

 

93

What are the benefits of warming SQ fluids before administration?

Encourages absorption and benefits hypothermic patients

94

Dextrose solutions >2.5% should never be given SQ. Why?

Causes skin sloughing or abscesses

95

In what cases is intravenous fluid therapy the most preferable route?

When treating critically ill, severely dehydrated, hypovolemic or patients experiencing metabolic disorders

96

What route of fluid therapy is the most rapidly effective on blood volume?

Intravenous

97

What complications are associated with intravenous fluid therapy?

Infection

Phlebitis

Hematoma formation

Thrombosis

98

What bones are used for intraosseous fluid therapy?

Femur, humerous, wing of ileum

99

What fluid therapy route is excellent for access to peripheral circulation?

Intraosseous (absorption equivalent to intravenous)

100

What route of fluid therapy is commonly used in guinea pigs, rodents, and hamsters?

Intraperitoneal

101

Intraperitoneal has the same absorption rate of what other route?

SQ

102

What affects rate of fluid administration?

Disease

Rate of fluid loss

Clinical signs

Cardiac and renal function

Fluid type and administration

103

Daily fluid requirements =

Replacement +

Maintenance +

Ongoing losses

104

Fluid Deficit=

% dehydration X body weight (kg) X 10

105

What is the best way to evaluate the fluid status of a patient?

Central venous pressure

Monitoring reduces chance of volume overload

106

What measures central venous pressure?

Manometer

107

What are the signs to fluid overload?

Hyperpnea (panting)

Nasal discharge

Chemosis (swelling of conjunctiva)

Pitting Edema

108

If fluid overload is suspected what should be monitored?

Lungs for pulmonary edema

109

How does the veterinarian know how much fluid to give an animal?

Volume needed to rehydrate the patient + volume needed for maitenance + volume needed to correct ongoing losses

110

What is the approximate maintenance fluid requirement?

66 ml/kg/day

111

When measuring contemporary (on going losses) what is being observed and how should it be measured?

Volume lost in diarrhea, or vomitus in ml's

Double visual estimate
