Question | Answer |
---|---|
Maternal Signs of Impending Birth | gestation ~340d udder development elevation of tailhead vulvar elongation waxing increase calcium in mammary secretions inversion of sodium:potassium in secretions |
Three Infectious Portals in Foal | GI respiratory navel |
"1-2-3" Rule | 1 hr = standing 2 hr = nursing 3 hr = pass placenta |
Timing of: suckle urination meconium nursing | 20min 10hr 24hr 7x/hr for 21-25% of BW/day |
Normal Pulse of Gestational Foal | <5min = 40-80 bpm 5-60min = 130-150 bpm 1-3d = 100 bpm |
Normal Respiratory Rate of Gestational Foal | post-foaling = 60-80 bpm 1-12hr = 30-40 bpm |
Most Common Congential Intracardiac Defect of Foal | ventricular septal defect |
Meconium | dark brown to black pelleted to pasty first feces composed of glandular secretions and swallowed amniotic fluid that are stored in colon and rectum |
Lethal White Foal Syndrome | Terminal Ileocolonic Agangliosis homozygous recessive from mating of 2 overo paints aganglionosis of colon |
Most Common Congenital Urinary Defect of Foal | ruptured bladder |
Earliest Indicator of Poor Foal Doing | decreased close bonding to the mare |
Mare Should Pass Placenta Within... | 2 hours becomes an emergency at 4-6 hrs |
Antibiotics that Cross Placenta | normal/inflamed: TMS-SMZ + Pentoxyphylline inflamed: KPen + Gentamicin |
Signs of Fetal Readiness for Birth | >330d gestation good quality colostrum in udder soft cervix |
Leading Causes of Foal Death in 1st 14d of Life | sepsis asphyxa dysmaturity from in utero growth retardation |
At What Age is a Foal Considered "Premature"? | <320d |
Clinical Signs of a Premature Foal | decreased body weight hypotonia soft, floppy ears short, silky haircoat bulging forehead incomplete endochondral ossification PaO2 <80mmHg |
Dysmature | >320d GA with signs of prematurity |
Postmature | >356d GA with lean, lanky appearance characteristic of chronic placental insufficiency |
Postterm | >356d GA, but normal |
Primary Cause of Prematurity in Foal | placental insufficiency |
Optimal Absorption Window of Colostrum | prior to 6.5 hours with essentially none after 24 hours |
Sites of Neonatal Infection | pneumonia GI tract (diarrhea) meninges physes kidney umbilicus joints |
Primary Cause of Neonatal Septicemia | E. coli |
Antimicrobials Used to Tx Neonatal Septicemia | beta-lactams + aminoglycosides meningitis --> 3rd generation cephalosporins |
Three Main Differentials for Neonatal Colic | ruptured bladder meconium impaction GI ulcers |
When does the Inflammatory Phase of Wound Healing Peak? | 3-5 days |
Four Phases of Wound (Tissue) Healing | inflammatory phase debridement phase repair phase (epithelialization, fibroplasia, granulation, contraction) maturation phase |
Debridement Phase of Wound Healing Begins | 6 hours post-injury |
Epithelialization Phase of Wound Healing Begins | 12 hours post-injury |
Fibroplasia Phase of Wound Healing Begins | 3-4 days post-injury |
Granulation Phase of Wound Healing Begins | 10-14 days post-injury |
Collagen Synthesis Begins | 5 days post-injury |
Rx Used to Help Provide Adequate Wound Drainage | Tris-EDTA (don't use on bone, b/c will chelate exposed bone) |
Removal of Stitches | 10-14 days |
Abnormal Synovial Fluid Cytology Parameters | protein >2.5 g/dl WBCs >10K-30K >90% rarely degenerate neutrophils |
Most Common Organisms in Foal Septic Arthritis | actinobacillus e. coli klebsiella pseudomonas |
Most Common Organisms in Adult Septic Arthritis | streptococcus staphylococcus e. coli |
Rx for Septic Arthritis | beta-lactams (tetracyclines) aminoglycosides fluoroquinolone |
