Effects of Peripheral Nerve Block on Perioperative Recovery following Major Thoracic and Abdominal Surgery: A Retrospective Cohort Study With Propensity-score Matching

The use of PNB was associated with shortened length of hospital stay and reduced major complications in older patients after major non-cardiac thoracic and abdominal surgery, possibly due to improved analgesia.
Study context
- Population
- Patients aged ≥65 years undergoing major (≥2 hours) non-cardiac thoracic and abdominal surgery under GA1,174 matched
- Participants
- 1,915 patients
- Exposure
- Peripheral nerve block (PNB) vs no PNB during GA
- PNBn = 587
- Without PNBn = 587reference
- Outcome
- Length of hospital stay
