Key result
Skin tissue perfusion measured by laser speckle contrast imaging decreased significantly from 301 PU before induction to 103 PU at the end of CABG surgery (P<0.05).
Why the study?
The study was conducted to evaluate the relationship between laser speckle contrast imaging and perfusion markers during CABG, and to investigate its relationship with extubation time in the intensive care unit.
Does laser speckle contrast imaging (LSCI) detect microcirculatory changes earlier than standard systemic perfusion markers in patients undergoing on-pump CABG, and does it correlate with extubation time?
Observational (n=15)

Absolute Event Rate: 103% vs 301%
p-value: p=<0.05
Laser speckle contrast imaging can detect early skin hypoperfusion during on-pump CABG that is not apparent on standard macrohemodynamic monitoring, and lower skin perfusion correlates with prolonged postoperative intubation time.
LSCI may detect early microcirculatory hypoperfusion in on-pump CABG missed by systemic markers; leaves open its predictive value for extubation time.

Ulugöl et al. (2023) conducted an observational in Coronary artery bypass grafting (CABG) (n=15). Laser speckle contrast imaging (LSCI) vs. Pre-induction baseline was evaluated on Skin perfusion levels measured by LSCI (Perfusion Units) at the end of surgery compared to pre-induction (p=<0.05). Skin tissue perfusion measured by laser speckle contrast imaging decreased significantly from 301 PU before induction to 103 PU at the end of CABG surgery (P<0.05).
