Effect of laparoscopic cholecystectomy intermittent pneumatic compression combined with medical compression stockings on deep vein hemodynamics of lower limb

Abstract

Objective To study the effect of laparoscopic cholecystectomy (LC) intermittent pneumatic compression combined with medical compression stockings on deep vein hemodynamics of lower limb. Methods Color Doppler ultrasound was adopted to evaluate the diameter and blood velocity in the lower extremity of 200 patients undergone LC from from April 2012 to September 2014 in our hospital. Pressure pump alone, medical compression stockings alone or combination of medical compression stockings with pressure pump in CO2 gas emissions before (T1) and 6 h (T2) after surgery was applied during laparoscopic surgery. Results At T1, patients’ femoral vein diameter and flow rate were (7.88±1.03) mm and (20.50±2.17) cm / s in combination group, (9.83±1.10) mm and (13.88±2.04) cm / s in single-use compression stockings group, and (9.75±1.21) mm and (15.75±2.01) cm / s in single-use pressure pump group, resptively. There was significant difference among groups (P<0.05). At T2, patients’ femoral vein diameter and flow rate were (6.87±0.96) mm and (24.60±2.25) cm / s in combination group, (8.56±0.97) mm and (18.37±1.90) cm / s in single-use compression stockings group and (7.95±1.03) mm and (19.60±2.16) cm / s in single-use pressure pump group, respectively. There was significant difference among groups (P<0.05). As compared with single-use compression stockings and pressure pump groups, the femora vein diameter was decreased (P<0.05), and the velocity increased (P<0.05) in combination group. Conclusion The combination of medical compression stockings and pressure pump is more beneficial than a single application for the return of blood, and more effectively prevents the occurrence of deep vein thrombosis.
