Update: Feline S/D discontinued

UPDATE

The supplier told me today that Feline S/D had been discontinued by Hills since 9 months ago. I told him I saw a can being given by Vet 2 recently to the cat with bladder stones I operated on.

He said that feline C/D does dissolve struvites as well and is recommended for cats with calcium oxalate too, targeting the urine pH = 6.2-6.4.

Follow up: Stone analysis results for cat with bladder stone

Report received today.

Calcium, oxalate, magnesium positive.
Preventive diet will be C/D for life
Target urinary pH to be 6.2 to 6.4

1403. SOP - Urethral obstruction in a male cat

Written: Feb 28, 2013  10.49 am reviewing this case to compare to the cat with bladder stones operated.

Feb 28, 2013

Urethral obstruction in cats may be quite common. A lady phoned me near midnight about her cat's difficulty in urination 2 days ago but she did not want to go to the emergency clinic I referred her to. So, I presumed this 13-year-old male neutered black and white cat to be the owner who came on Feb 28, 2013 as he cat could not pass urine and had blood in the urine passed.

"No, I did not phone you," the lady in her late 40s said to me as I palpated a bladder the 50% the size of a Thai mango.

"How long had he been having this problem?" I asked.
"Two days."
"Did he vomit?" I wanted to ascertain the kidney involvement as owners seldom volunteer this info.
"He vomited 3 times yesterday."
"He must be eating dry cat food since young," I predicted.
"Yes," she said. I feed dry IAMS and ikan bilis since he was young."
"He seldom drinks water," I said.
"You are correct."

This was a gentle old cat. He did not like me massaging his penile area to loosen the urethral plug and hissed.

Standard Operating Procedure (SOP). Emergency treatment usually

1. Sedate the cat. Collect blood and urine if possible. Blood collected. No urine
2. I Injected SC baytril and tolfedine. I used xylazine 0.1 and ketamine 0.4 ml IM. Sufficient.
3. Collect urine via catheter. This was not possible as the urethra was severely blocked at the bend of the penile area.
4. Put saline into syringe and flush into catheter to unblock. This was successful. Do not force catheter inwards as this tramatise the urethra as I had seen a vet doing it. Sedate first.
5. Urine flows out. Collect for urine analysis.
6. Irrigate bladder with saline and suck out any sand and blood
7. Stitch 3 areas catheter with absorbable to anchor catheter for 2 days. Blood still flows out on Day 2 (today).
8. Hospitalised overnight and goes home next day.

BLOOD TEST RESULTS
Urea 59 (7-11)
Creatinine 1003  (7-160)
Platelets 93  (300-800). Cat's mucous membranes were pale. Nose looked pale as compared to normal cat.

URINE
pH 6.5  SG 1.012 (not reliable as saline was used to unblock obstruction)
Blood 4+, Bacteria 3+, no crystals
(No crystals does not mean no bladder stone. Palpation of bladder on Day 2 - no hard stones). No urethral obstruction as catheter is in place.

X-RAYS not done to reduce cost for this first occurrence. Will do if recur.

ADVICE
Change slowly to canned food. Urine analysis 1 month later. K/D for 10 days. Seldom gets followed up as most owners don't comply.

1402. Digital images of 83g hamster now 77g after surgery

Make use of digital photography to show tumours excised, hamster recovering etc as the owner will be educated and happier to know what had happened. This hamster of 83 g was not knocked down by 3 drops of Zoelietil 50 IM today. I thought it was too little. After 5 minutes, he became drowsy. Clipped and excised the large left inguinal tumours and left ear wart. Weighed him. He was 77 g and pooped a lot. Owner was pleased.

1401. Abdominal cryptorchid in a dog

"Is the vet competent?" the owner asked me. The young male dog had been sent in for neutering. Two undescended testicles. So, just get on with the operation. Many times, there is no problem locating the two undescended testicles under the skin.

However veterinary surgery throws the vet a surprise. In this dog, one testicle was located. The only was nowhere under the skin!

Be meticulous. Make a thorough examination before any surgery. If the undescended testicle cannot be felt under the skin while the dog is standing, don't expect to find it when he is on his back! There will be a lot of doubts from the owner when the vet can't find this testicle as it is inside the abdomen.
Have an examination procedure. Verify gender. Verify presence of both undescended testicles under the skin. If not, let the dog owner know immediately and open up the abdomen. The abdominal testicle usually is located next to the bladder at the side.
Be humble if you don't know and ask your senior vet what to do.

1398. Domitor + Ketamine Anaesthesia for spay duration + KPI

 
Feb 27, 2013  I spayed a 7-month-old Maltese X., 4.3 kg. The happy couple took leave and made an appointment with me. Usually spays are done by Dr Daniel as they are routine surgeries. This dog had been vigorously licking her vulval lips such that the area above the vulva became black. "Much less licking after antibiotics last month," the lady in her late 20s said to me. I had advised spaying as there could be pyometra which leaked out vaginal discharge causing the need to lick. It could be a urinary tract infection too. The dog was on heat with uterine horns and ovaries very red and congested when I spayed her. 

ANAESTHESIA
Based on formula of 10 kg, young healthy dog Dom=0.4 and Ket=0.5, I gave this 4.3 kg dog IV Dom=0.2 + Ket = 0.17 totalling 0.37 ml IV one syringe with 0.13 ml Hartmann.

A: Injection of D+K IV  10.22 am
B: Isoflurane first given  10.43 am
C: Isoflurane stopped    10.53 am
D: First skin incision: 10.34 am
E: Completion of skin stitching: 11.01 am.

E-A = 39 minutes. This is because the dog started moving at 10.43 am (21 minutes after injecton) and the surgery was paused to give gas by mask to stabilise. This shows that duration of D + K is 21 minutes for this dog. Spay should be completed in 21 minutes but there was some delay as there was training of the new veterinary staff on gas anaesthesia.  Without traiining, spay should be completed in 30 minutes for this small breed.  

E-D= 27 minutes. Dog was on heat. More time was spent ensuring no bleeding and on speed on hooking out the ovaries.
Hooking left ovary took 3 trials and it was hooked out at 10.38 am. 4 minutes after incision. Right ovary was hooked out at 10.42 am, 8 minutes after skin incision.

Conclusion: Usually the above formula gives at least 20 minutes of surgical anaesthesia. If spay takes longer, isoflurane top up is needed. Efficiency and timing are important in productivity of a vet surgeon. Taking too long to spay a dog is not good.

Conclusion:
Much time was wasted between first skin incision and injection (D-A=12 minutes) as I was teaching a new assistant since Mr Min was poached. He had worked 2 years for me and I wished him well as he ought to move on for a better future and more income. Surgery should commence around 7 minutes around injection as IV effects would occur in 5 minutes usually. Check reflexes for surgical anaesthesia like eyelid blinking. 5 minutes extra off the E-D process would mean that I would take 22 minutes and would not need isoflurane top up. The planning and proper prompt process is essential in veterinary surgery procedures and process and in less wastage of resources.
