Perioperative medicine & outcomes
Perioperative continuous body weight measurements with load cells under the bed legs in patients undergoing abdominal surgery
Authors' conclusion
Both perioperative fluid balance calculation and body weight measurement may have different but mutually complementary roles in perioperative managements.
Study context
- Population
- Adults undergoing elective abdominal surgery under GA
- Participants
- 20 adults
- Outcome
- Body weight (continuous, load cells under bed legs)
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Body weight
- Body weight increase immediately after surgery (mean ± SD), ≈5% of preoperative weight
- 2.7 ± 1.3 kg
- Increase not correlated with intraoperative fluid balance
- P = 0.178
- Intraoperative fluid balance; weight increase significantly greater (P < 0.001)
- 1.5 ± 0.4 kg
- Body weight returned to preoperative level
- POD3
- Body weight at POD6 vs preoperative (P < 0.001)
- 97%
Observational data: associations, not effects.
Further findings
Nocturnal weight loss pattern
- Physiological nocturnal weight loss maintained throughout hospitalisation except when fluid infused
Body movements and bed occupancy
- Longer in bed, smaller movements, fewer daytime bed exits until POD3 vs preoperative
- Greater nocturnal movements, smaller diurnal variation after POD4
