Key result
Sustained pneumatic compression of the lower extremities significantly reduced the incidence of hypotension compared to no compression (3.6% vs 32.1%) during anesthesia induction in patients aged 65 years or younger.
Why the study?
Does sustained or sequential pneumatic compression of the lower extremities improve hemodynamic stability during anesthesia induction compared to no compression?

Sustained pneumatic compression without… vs No compression
Design
RCT, Randomly assigned to one of three groups
Follow-up
During anesthesia induction (before tracheal intubation)

Sustained pneumatic compression of the lower extremities provides hemodynamic stabilization during anesthesia induction in patients aged 65 years or younger, but not in older patients.
Lim et al. (2018) conducted an RCT in Patients undergoing elective major operations requiring invasive monitoring (n=171). Sustained pneumatic compression vs. No compression or sequential pneumatic compression was evaluated on Incidence of hypotension (MAP < 60 mmHg) in patients aged ≤ 65 years (p=0.015). Sustained pneumatic compression of the lower extremities significantly reduced the incidence of hypotension compared to no compression (3.6% vs 32.1%) during anesthesia induction in patients aged 65 years or younger.
