🔍 Key Findings Summary
- Population: 35 nonbrachycephalic dogs undergoing orthopedic procedures (TPLO)
- Study design: Prospective observational using transnasal Digitrapper dual-sensor pH probe after short TIVA
- Upper reference limits:
- Distal GER events per hour: 2.4
- Proximal GER events per hour: 0.4
- Cumulative distal acid exposure: 2.3%
- Cumulative proximal acid exposure: 0%
- Median values (normal):
- Distal GER events per hour: 0.3
- Proximal GER events per hour: 0
- Proximal GER observed in 12/31 dogs
- No regurgitation observed in any dog
- No major adverse events with probe use
- Clinical implication: These parameters provide a reference for assessing excessive GER in future canine surgical cases
