Reader JAVMA 2020 - Comparison of liposomal bupivacaine and 0.5% bupivacaine hydrochloride for control of postoperative pain in dogs undergoing tibial plateau leveling osteotomy
What was the outcome of this study?
How is liposomal bupivicaine administered?
Dogs administered liposome-encapsulated bupivacaine were less likely to require rescue analgesia and received lower amounts of opioids than 0.5% bupivacaine.
By tissue infusion

How did preop Maropitant and Metoclopramide admin affect the ris of GE reflux?
What variables were associated with an increased risk of GER?
No decrease in risk of GE reflux
Male (OR 9.2), overweight (OR 12.3), GI surgery (OR 30) and requirement for dexmed CRI post-op (OR 9.6)
Araos VS 2024 - Effect of continuous positive airway pressure helmet on respiratory function following surgical procedures in brachycephalic dogs: A randomized controlled trial
How did use of the CPAP affect the resp function?
SpO2, PaCO2 or rectal temp not affected
Improved PaO2/FiO2 (increased)
Kazmir-Lysak JFMS 2023 - Use of wound infusion catheters for postoperative local anaesthetic administration in cats
What factor was associated with an increased complication rate?
Volume of single dose of LA delivered through catheter (larger volume - higher risk of comp)
Li JFMS 2024 - Effect of oral administration of pregabalin on physiological and echocardiographic variables in healthy cats
What complication was seen upon administration of pregabalin? And what doses was it associated with?
Hypotension - 5 and 10mg/kg - not seen in 2.5mg/kg group

What was observed?
Gabapentin may decrease arterial BP in cats w. and w.out CKD
Yu LU JAVMA 2023 - Evaluation of complications and long-term outcomes associated with 101 dogs and cats discharged with and without subcutaneous active closed-suction drains (2014–2022)
What was the rate of complications with discharging an animal from hosp w. an active drain (vs removing prior to discharge?
37% for outpatient active suction drains vs 4%
Gomes Quitzan VS 2020 - Evaluation of the performance of an endoscopic 3mm electrothermal bipolar vessel sealing device intended for single use after multiple use-and-resterilisation cycles
What resterilisation technique was utilised?
How many uses did the VSD fail after?
Hydrogen peroxide plasma resterilization
10
McChesney VS 2021 - Evaluation of depth gauge accuracy in a canine tibial plateau levelling osteotomy model
Which types of drill holes had the greatest bone measurement variability?
What feature of the depth gauge influenced it’s measurements?
Stacked combination hole
Mean depth gauge measurements were smaller (c.f. micrometer by:
2.20 mm for the compression hole
0.82 mm for the combination hole
3.57 mm for the stacked combination hole
Base diameter <5mm - smaller than values measured with base diameter >5.5mm
Mayhew VS 2020 - Cadaveric evaluation of fluoroscopy-assisted placement of one-lung ventilation devices for video-assisted thoracoscopic surgery in dogs
Which of the two one-lung ventilation devices was more efficient and easier to place?
EZ-blocker
(c.f. double-lumen endobronchial tube)
Anderson VS 2019 - Complications related to entry techniques for laparoscopy in 159 dogs and cats
What the reported complication rate? And what % were minor?
What two factors were associated with decreased complication rate?
21% of which 91% were minor (CO2 leak, requirement for repeated entry, omental insufflation)
Midline entry (c.f. paramedian), Ternamian visial entry (c.f. modified Hasson and Veress needle)
Gordo JSAP 2020 - Feasibility of the single-incision subxiphoid approach for video-assisted thoracoscopic surgery in dogs
Describe the single-incision subxiphoid approach
What was the success rate?
See pic
50% (5/10) - 3 required additional intercostal port, 1 lacerated v.cava and 1 had adhesions
Kuvaldina VS 2023 - Development of a minimally invasive endoscopic technique for excisional biopsy of the axillary lymph nodes in dogs
Describe the approach
Lat recumbency.
Division between dorsal border of superficial pectoralis + ventral border latissimus dorsi
3 cm skin incision starting caudal to the caudal border of the m. triceps brachii
Muscular junction separated by blunt dissection and two stay sutures placed in these muscles.
Latissimus dorsi muscle margin was elevated and reflected through the incision to expose the deep surface of the muscle belly. When present, the accessory axillary node was located adhered to the deep surface of the muscle
