TextSentencer_T102 8746-8831 Sentence denotes Next, apply strips of adhesive tape to the patient's paw on either side, if possible.
TextSentencer_T103 8832-8939 Sentence denotes The strips (stirrups) will be used to hold the bandage in place and prevent it from slipping down the limb.
TextSentencer_T104 8940-8991 Sentence denotes Wrap the intermediate layer over the contact layer.
TextSentencer_T105 8992-9101 Sentence denotes Turn the adhesive strips around so that the adhesive layer can be secured to the intermediary layer in place.
TextSentencer_T106 9102-9154 Sentence denotes Wrap the final, or tertiary, layer over the bandage.
TextSentencer_T107 9155-9219 Sentence denotes The function of a wet-to-dry bandage is to help debride a wound.
TextSentencer_T108 9220-9297 Sentence denotes The moistened gauze dries and is pulled off the wound at each bandage change.
TextSentencer_T109 9298-9377 Sentence denotes Dry necrotic tissue and debris that adhere to the gauze are pulled off with it.
TextSentencer_T110 9378-9497 Sentence denotes In addition, the moistened material dilutes the wound exudate and enhances its absorption into the gauze contact layer.
TextSentencer_T111 9498-9649 Sentence denotes If large amounts of exudate come from the wound, the contact layer and intermediate layer absorb the exudate, wicking the material away from the wound.
TextSentencer_T112 9650-9765 Sentence denotes Finally, delivery of medications into the wound can occur to promote the development of healthy granulation tissue.
TextSentencer_T113 9766-9926 Sentence denotes oPen Wound in rePAir sTAge oF heAling Early Repair During the early stage of repair, granulation tissue, some exudate, and minor epithelialization are observed.
TextSentencer_T114 9927-10195 Sentence denotes Place a nonadherent bandage with some antibacterial properties (petroleum-or nitrofurazone-impregnated gauze) or absorbent material (foam sponge, hydrogel, or hydrocolloid dressing) in direct contact with the wound to minimize disruption of the granulation tissue bed.
TextSentencer_T115 10196-10299 Sentence denotes Next, place an absorbent intermediate layer, followed by a porous outer layer, as previously described.
TextSentencer_T116 10300-10427 Sentence denotes Granulation tissue can grow through gauze mesh or adhere to foam sponges and can be ripped away at the time of bandage removal.

TextSentencer_T122 10860-10942 Sentence denotes With nonadherent dressings, wounds with viscous exudates may not be absorbed well.
TextSentencer_T123 10943-11040 Sentence denotes This may be advantageous and enhance epithelialization, provided that complications do not occur.
TextSentencer_T124 11041-11171 Sentence denotes Infection, exuberant granulation tissue, or adherence of absorbent materials to the wound may occur and delay the healing process.
TextSentencer_T125 11172-11295 Sentence denotes Moist healing is a newer concept of wound management in which wound exudates are allowed to stay in contact with the wound.
TextSentencer_T126 11296-11441 Sentence denotes In the absence of infection a moist wound heals faster and has enzymatic activity as a result of macrophage and polymorphonuclear cell breakdown.
TextSentencer_T127 11442-11511 Sentence denotes Enzymatic degradation or "autolytic debridement" of the wound occurs.
TextSentencer_T128 11512-11644 Sentence denotes Moist wounds tend to promote neutrophil and macrophage chemotaxis and bacterial phagocytosis better than use of wet-to-dry bandages.
TextSentencer_T129 11645-11861 Sentence denotes A potential complication and disadvantage of moist healing, however, is the development of bacterial colonization, folliculitis, and trauma to wound edges that can occur because of the continuously moist environment.
TextSentencer_T130 11862-11990 Sentence denotes 1 Use surfactant-type solutions (Constant-Clens, Kendall, Mansfield, Massachusetts) for initial wound cleansing and debridement.
TextSentencer_T131 11991-12100 Sentence denotes Use occlusive dressings for rapid enzymatic debridement with bactericidal properties to aid in wound healing.
TextSentencer_T132 12101-12247 Sentence denotes Bandage wet necrotic wounds with a dressing premoistened with hypertonic saline (Curasalt [Kendall] , 20% saline) to clean and debride the wounds.
TextSentencer_T133 12248-12348 Sentence denotes Hypertonic saline functions to desiccate necrotic tissue and bacteria to debride the infected wound.
TextSentencer_T134 12349-12419 Sentence denotes Remove and replace the hypertonic saline bandage every 24 to 48 hours.
TextSentencer_T135 12420-12582 Sentence denotes Next, place gauze impregnated with antibacterial agents (Kerlix AMD [Kendall] ) over the wound in the bandage layer to act as a barrier to bacterial colonization.
TextSentencer_T136 12583-12818 Sentence denotes If the wound is initially dry or has minimal exudate and is not obviously contaminated or infected, place amorphous gels of water, glycerin, and a polymer (Curafil [Kendall] ) over the wound to promote moisture and proteolytic healing.
TextSentencer_T137 12819-12897 Sentence denotes Discontinue moisture gels such as Curafil once the dry wound has become moist.
TextSentencer_T138 12898-13009 Sentence denotes Finally, the final stage of moist healing helps to promote the development of a healthy granulation tissue bed.
TextSentencer_T139 13010-13145 Sentence denotes Use calcium alginate dressings (Curasorb or Curasorb Zn with zinc [Kendall] ) in noninfected wounds with a moderate amount of drainage.
TextSentencer_T140 13146-13236 Sentence denotes Alginate gels promote rapid development of a granulation tissue bed and epithelialization.
TextSentencer_T141 13237-13335 Sentence denotes Foam dressings also can be applied to exudative wounds after a healthy granulation bed has formed.
TextSentencer_T142 13336-13390 Sentence denotes Change foam dressings at least once every 4 to 7 days.
TextSentencer_T143 13391-13513 Sentence denotes The use of granulated sugar has become popular in recent years to treat open wounds that are contaminated and/or infected.
TextSentencer_T144 13514-13624 Sentence denotes Sugar possesses antibacterial properties and helps promote wound healing and development of a granulation bed.
TextSentencer_T145 13625-13834 Sentence denotes Sugar bandages are an excellent choice for shearing or degloving injuries, burns, and decubital ulcers, particularly ones that are infected with Pseudomonas species, Escherichia coli, or streptococcal species.
TextSentencer_T146 13835-14003 Sentence denotes The placement of a sugar bandage is similar to that of a wet-to-dry bandage, in that first the wound must be thoroughly lavaged with either tap water or sterile saline.
TextSentencer_T147 14004-14046 Sentence denotes Next, devitalized tissue must be debrided.
TextSentencer_T148 14047-14138 Sentence denotes Next, pour a thick layer (approximately 1 cm thick) of granulated sugar over the wound bed.
TextSentencer_T149 14139-14232 Sentence denotes Next, wrap the wound with sterile gauze squares, cotton bandage material, and an outer layer.
TextSentencer_T150 14233-14375 Sentence denotes Change the wound dressing at least once to twice daily initially, then once daily to every other day as the granulation bed becomes healthier.
TextSentencer_T151 14376-14473 Sentence denotes The sugar can be eliminated from the bandaging process once a healthy granulation bed is present.
TextSentencer_T152 14474-14801 Sentence denotes For closed wounds without any drainage, such as a laceration that has been repaired surgically, a simple bandage with a nonadherent contact layer (e.g., Telfa pad [Kendall] ), an intermediate layer of absorbent material, and an outer porous layer (Elastikon, Vetrap) can be placed to prevent wound contamination during healing.
TextSentencer_T153 14802-14879 Sentence denotes The nonadherent pad will not stick to the wound and cause patient discomfort.
TextSentencer_T154 14880-15012 Sentence denotes Because there usually is minimal drainage from the wound, the function of the intermediate layer is more protective than absorptive.
TextSentencer_T155 15013-15090 Sentence denotes Any small amount will be absorbed into the intermediate layer of the bandage.
TextSentencer_T156 15091-15255 Sentence denotes It is important with any bandage to place the tape strips or "stirrups" on the patient's limb and then overlap in the bandage, to prevent the bandage from slipping.
TextSentencer_T157 15256-15412 Sentence denotes Place the intermediate and tertiary layers loosely around the limb, starting distally and working proximally, with some overlap with each consecutive layer.
TextSentencer_T158 15413-15497 Sentence denotes This method prevents excessive pressure and potential impairment of venous drainage.
TextSentencer_T159 15498-15680 Sentence denotes Leave the toenails of the third and fourth digits exposed, whenever possible, to allow daily examination of the bandage to determine whether the bandage is impairing venous drainage.
TextSentencer_T160 15681-15799 Sentence denotes If the bandage is too tight and constricting or impeding vascular flow, the toes will become swollen and spread apart.
TextSentencer_T161 15800-15956 Sentence denotes When placed and maintained properly (e.g., the bandage does not get wet), there usually are relatively few complications observed with this type of bandage.
TextSentencer_T162 15957-16063 Sentence denotes In some cases it is necessary to cover a wound in which a Penrose drain has been placed to allow drainage.
TextSentencer_T163 16064-16164 Sentence denotes In many cases there is a considerable amount of drainage from the drain and underlying soft tissues.
TextSentencer_T164 16165-16428 Sentence denotes The function of the bandage is to help obliterate dead space created by the wound itself, absorb the fluid that drains from the wound and that will contaminate the environment, and prevent external wicking of material from the external environment into the wound.
TextSentencer_T165 16429-16603 Sentence denotes When the bandage is removed, the clinician can examine the amount and type of material that has drained from the wound in order to determine when the drain should be removed.
TextSentencer_T166 16604-16839 Sentence denotes When a bandage is placed over a draining wound, the contact layer should be a commercially available nonadherent dressing and several layers of absorbent wide-mesh gauze placed directly over the drain at the distal end of the incision.
TextSentencer_T167 16840-16965 Sentence denotes Overlay the layers of gauze with a thick layer of absorbent intermediate dressing to absorb fluid that drains from the wound.
TextSentencer_T168 16966-17233 Sentence denotes If the gauze and intermediate layers are not thick or absorbent enough, there is a potential for the drainage fluid to reach the outer layer of the bandage and provide a source of wicking of bacteria from the external environment into the wound, leading to infection.
TextSentencer_T169 17234-17389 Sentence denotes Minor Hemorrhage Some wounds such as lacerations have minor bleeding or hemorrhage that require an immediate bandage until definitive care can be provided.
TextSentencer_T170 17390-17611 Sentence denotes To create a pressure bandage, place a nonadherent dressing immediately in contact with the wound, followed by a thick layer of absorbent material, topped by a layer of elastic bandage material such as Elastikon or Vetrap.
TextSentencer_T171 17612-17816 Sentence denotes Unlike the bandage for a closed wound, the top tertiary outer layer should be wrapped with some tension and even pressure around the limb, starting from the distal extremity (toes) and working proximally.
TextSentencer_T172 17817-17910 Sentence denotes The pressure bandage serves to control hemorrhage but should not be left on for long periods.
TextSentencer_T173 17911-18030 Sentence denotes Pressure bandages that have been left on for too long can impair nerve function and lead to tissue necrosis and slough.
TextSentencer_T174 18031-18140 Sentence denotes Therefore pressure bandages should be used in the hospital only, so that the patient can be observed closely.
TextSentencer_T175 18141-18265 Sentence denotes If hemorrhage through the bandage occurs, place another bandage over the first until the wound can be repaired definitively.
TextSentencer_T176 18266-18379 Sentence denotes Removal of the first bandage will only disrupt any clot that has formed and cause additional hemorrhage to occur.
TextSentencer_T177 18380-18524 Sentence denotes Fractures require immediate immobilization to prevent additional patient discomfort and further trauma to the soft tissues of the affected limb.
TextSentencer_T178 18525-18621 Sentence denotes As with all bandages, a contact layer, an intermediate layer, and an outer layer should be used.
TextSentencer_T179 18622-18691 Sentence denotes Place the contact layer in accordance with any type of wound present.
TextSentencer_T180 18692-18803 Sentence denotes The intermediate layer should be thick absorbent material, followed by a top layer of elastic bandage material.
TextSentencer_T181 18804-19223 Sentence denotes An example is to place a Telfa pad over a wound in an open distal radius-ulna fracture, followed by a thick layer of cotton gauze cast padding, followed by an elastic layer of Kling (Johnson & Johnson Medical, Arlington, Texas) , pulling each layer tightly over the previous layer with some overlap until the resultant bandage can be "thumped" with the clinician's thumb and forefinger and sound like a ripe watermelon.
TextSentencer_T182 19224-19348 Sentence denotes The bandage should be smooth with consecutive layers of even pressure on the limb, starting distally and working proximally.
TextSentencer_T183 19349-19530 Sentence denotes Leave the toenails of the third and fourth digits exposed to allow monitoring for impaired venous drainage that would suggest that the bandage is too tight and needs to be replaced.
TextSentencer_T184 19531-19650 Sentence denotes Finally, place a top layer of Vetrap or Elastikon over the intermediary layer to protect it from becoming contaminated.

T3152 71395-71557 Sentence denotes An increased serum sodium concentration implies hyperosmolality, whereas a decrease in serum sodium concentration usually, but not always, implies hypoosmolality.
T32057 71558-71775 Sentence denotes The severity of clinical signs of hypernatremia and hyponatremia is related primarily to the rapidity of the onset of the change rather than to the magnitude of the associated plasma hyperosmolality or hypoosmolality.
T5717 71776-71968 Sentence denotes Clinical signs of neurologic disturbances include disorientation, ataxia, and seizures, and coma may occur at serum sodium concentrations less than 120 mEq/L or greater than 170 mEq/L in dogs.
T96405 71969-72362 Sentence denotes Therapy for hypernatremia or hyponatremia with fluid containing low or higher concentrations of sodium should proceed with caution, because rapid changes (decreases or increases) in serum sodium and osmolality can cause rapid changes in the intracellular and extracellular fluid flux, leading to intracellular dehydration or edema, even though the serum sodium has not been returned to normal.

T20966 76497-76763 Sentence denotes A crystalloid fluid contains crystals of salts with a composition similar to that of the extracellular fluid space and can be used to maintain daily fluid requirements and replace fluid deficits or ongoing fluid losses (Table 1- *30 × Body weight (kg) + 70 = mL/day.
T11813 76764-76769 Sentence denotes Note:
T57417 76770-76955 Sentence denotes This formula will slightly underestimate the requirements for patients that weigh less than 2 kg and will slightly overestimate the requirements for patients that weigh more than 70 kg.

T90159 78115-78290 Sentence denotes A colloid is a large-molecular-weight particle that acts as an effective volume expander by drawing fluid from the interstitial fluid compartment into the intravascular space.
T104 78291-78484 Sentence denotes When administered with a crystalloid, a colloid serves to hold or retain the crystalloid fluid within the vascular space for a longer time than if the crystalloid fluid were administered alone.
T68342 78485-78654 Sentence denotes Because of this property, colloids can promote better tissue perfusion at lower infusion volumes and equivalent colloid oncotic pressures and mean BPs than crystalloids.
T52015 78655-78786 Sentence denotes Administer the synthetic colloids in incremental boluses of 5 to 10 mL/kg over 5 to 15 minutes during the treatment of hypotension.

T37051 96040-96127 Sentence denotes If mechanical ventilation is required, 24-hour one-on-one veterinary care is necessary.
T47936 96129-96213 Sentence denotes A noninvasive means of determining oxygenation is through the use of pulse oximetry.
T26090 96214-96486 Sentence denotes A pulse oximeter uses different wavelengths of light to distinguish characteristic differences in the properties of the different molecules in a fluid or gas mixture-in this case, oxygenated (oxyhemoglobin) and deoxygenated hemoglobin (deoxyhemoglobin) in pulsatile blood.
T82534 96487-96524 Sentence denotes The process is termed pulse oximetry.
T34121 96525-96638 Sentence denotes Oxyhemoglobin and deoxyhemoglobin are different molecules that absorb and reflect different wavelengths of light.
T6022 96639-96766 Sentence denotes Oxyhemoglobin absorbs light in the infrared spectrum, allowing wavelengths of light in the red spectrum to transmit through it.
T74858 96767-96916 Sentence denotes Conversely, deoxyhemoglobin absorbs wavelengths of the red spectrum and allows wavelengths in the infrared spectrum to transmit through the molecule.
T96962 96917-97027 Sentence denotes The spectrophotometer in the pulse oximeter transmits light in the red (660 nm) and infrared (920 nm) spectra.
T54095 97028-97165 Sentence denotes The different wavelengths of light are transmitted across a pulsatile vascular bed and are detected by a photodetector on the other side.
T13544 97166-97469 Sentence denotes The photodetector processes the amount of light of varying wavelengths that reaches it, then transmits an electrical current to a processor that calculates the difference in the amount of light originally transmitted and the amount of light of similar wavelength that actually reaches the photodetector.
T11616 97470-97794 Sentence denotes The difference in each reflects the amount of light absorbed in the pulsatile blood and can be used to calculate the amount or ratio of oxyhemoglobin to deoxyhemoglobin in circulation, or the functional hemoglobin saturation, by the following formula: where Hbo 2 is oxygenated hemoglobin, and Hb is deoxygenated hemoglobin.
T62246 97795-97879 Sentence denotes Four molecules of oxygen reversibly bind to hemoglobin for transport to the tissues.
T38889 97880-98018 Sentence denotes Carbon monoxide similarly binds to hemoglobin and forms carboxyhemoglobin, a molecule that is detected similarly to oxygenated hemoglobin.
T68257 98019-98110 Sentence denotes Thus Sao 2 as detected by a pulse oximeter is not reliable if carboxyhemoglobin is present.
T55040 98111-98211 Sentence denotes In most cases, pulse oximetry or Sao 2 corresponds reliably to the oxyhemoglobin dissociation curve.
T88160 98212-98292 Sentence denotes Oxygen saturation greater than 90% corresponds to a Pao 2 greater than 60 mm Hg.
T16807 98293-98496 Sentence denotes Above this value, large changes in Pao 2 are reflected in relatively small changes in Sao 2 , making pulse oximetry a relatively insensitive method of determining oxygenation status when Pao 2 is normal.
T40927 98497-98730 Sentence denotes Because pulse oximetry measures oxygenated versus nonoxygenated hemoglobin in pulsatile blood flow, it is fairly unreliable when severe vasoconstriction, hypothermia, shivering or trembling, or excessive patient movement are present.
T77596 98731-98934 Sentence denotes In addition, increased ambient lighting and the presence of methemoglobin or carboxyhemoglobin also can cause artifactual changes in the Sao 2 , and therefore the measurement is not reliable or accurate.
T92066 98935-99009 Sentence denotes Most pulse oximeters also display a waveform and the patient's heart rate.
T36414 99010-99203 Sentence denotes If the photodetector does not detect a good-quality signal, the waveform will not be normal, and the heart rate displayed on the monitor will not correlate with the patient's actual heart rate.
T92353 99204-99302 Sentence denotes The efficiency of ventilation is evaluated using the Paco 2 value on an arterial blood gas sample.
T26512 99303-99408 Sentence denotes Alternatively, a noninvasive method to determine end-tidal carbon dioxide is through use of a capnograph.
T54104 99409-99508 Sentence denotes The science of capnometry uses a spectrophotometer to measure carbon dioxide levels in exhaled gas.
