Pelvic limb anaesthesia and analgesia in dogs undergoing tibial plateau levelling osteotomy (TPLO): A survey of board-certified anesthesiologists
Objective: To report veterinary anesthesiologists' locoregional anesthesia and analgesia preferences for use in dogs undergoing a TPLO and determine any association with specialty college, time from board certification, or employment sector.
Study design: Cross-sectional study.
Sample population: Diplomates of the American (ACVAA) and European (ECVAA) Colleges of Veterinary Anesthesia and Analgesia.
Methods: An electronic survey was distributed to diplomates, and responses were used to determine associations between preferred methods.
Results: The survey response rate was 28% (141/500), with 69% (97/141) of ACVAA diplomates and 31% of diplomates with ECVAA (44/141) certification. Peripheral nerve block (PNB) was preferred by 79% (111/141) of all diplomates, lumbosacral epidural (LE) by 21% (29/141), and peri-incisional infiltration (PI) by <1% (1/141). There was no association (p = .283) with specialty college. There was an association (p < .001) with time from board certification with increased preference for LE when > 10 years from certification and PI preferred by only those board-certified > 20 years ago. There was an association with the employment sector (p = .003), with more academic diplomates preferring LE. Anesthesiologists reported that treatment decisions were affected by factors including time pressure and surgeon influence.
Conclusion: Diplomates of ACVAA and ECVAA prefer PNB as the locoregional method of pelvic limb anesthesia in dogs undergoing TPLO. A significant percentage of newer and private practice diplomates prefer PNB, while a substantial percentage of senior and academic diplomates prefer LE. Decision-making is multifactorial and includes perceived time pressure and surgeon influence.
Clinical significance: Veterinary anesthesiologists prefer and frequently use PNB in dogs undergoing TPLO, and surgeon influence may affect their chosen treatment.
