Uterine Diseases Flashcards
How many percent develop uterine infections
40%
How long must foetal placenta be retained for it to be RFM
If placenta is not passed within 6-12h
Risk factors for RFM
Premature birth/Abortion/Csection/Twins/Induced calving
Placentitis- Brucella/Trauma
Failure of uterine contraction-Twins/Dystocia/Hypocalcaemia
Tx of RFM
Oxytocin IM if difficult calving
Calcium SC if older
Manual removal with/out Intrauterine AB- But introduces bacteria and causes trauma
Leave and monitor temp and general condition. If high temp NSAIDS/Fluids/AB
What is metritis
Inflammation of ALL uterine layers. Often a consequence of RFM
95% of metritis happens in what phase of post partum
First 2 weeks
Difference between clinical and puerperal metritis
Clinical: No systemic
Puerperal metritis: Systemic signs
C/S of Metritis
Depression, inappetence, agalactia, pyrexia
Vaginal discharge
Smelly, watery, homogeneous, commonly red-brown
Uterus distended
Hypotermia, peritonitis, death
Outline the 3 grade system to grade metritis
G1: Enlarged Uterus, Purulent discharge, No systemic
G2: Clinical metritis
G3: Toxaemia-Collapse/Depression
Treatment of acute post partum metritis
Parental antibiotics
NSAIDS
Fluids Oral/ Hypertonic IV
Dx of subclinical endometritis
No C/S. Poor reproductive perf
Uterine lavage
Cytobrush cytology
Will clinical endometritis show any systemic signs
No
C/S of Clinical endometritis
Not sick cow
Poor performance
Purulent vaginal discharge
Uterus not fully involuted
Dx of Endometritis
ULTRASOUND
Purulent vaginal discharge over 50% cloudy
Vaginal examination using vaginoscope
Transrectal palpation
What do I see on U/S if endometritis
One dark square of anoechoic fluid filled
Tx of Endometritis
Metricure-Intrauterine antibiotic
PGF2A if there is no CL causing lysis of CL opening to drain discharge
Risk factor/cause of pyometra
Cows ovulate early post partum in a contaminated uterus
Difference between endometritis and pyometra
Pyometra ALWAYS has CL and easy diagnosis
Pyometra has easier treatment
How to monitor uterine disease
Daily assessment of appetite, appearance, attitude and production
Physical examination (postpartum check)
Vaginal exam (RFM, metritis & PVD)
Rectal temperature
Cow side measures (BCS, rumen fill, BHB)
