Perioperative thromboelastography analysis during suction-assisted lipectomy: a prospective cohort study.

Area of Science:

• Coagulation science
• Plastic surgery
• Thromboelastography

Background:

• Understanding blood coagulation changes during cosmetic procedures is crucial for patient safety.
• Suction-assisted lipoplasty (SAL) is a common aesthetic procedure, but its impact on hemostasis requires detailed investigation.
• Traditional coagulation tests may not fully capture dynamic hemostatic changes during surgery.

Purpose of the Study:

• To prospectively investigate coagulation dynamics during suction-assisted lipoplasty (SAL).
• To compare coagulation profiles in SAL patients versus those undergoing other plastic surgery procedures.
• To utilize a computerized thromboelastograph coagulation analyzer (TEG) for real-time coagulation assessment.

Main Methods:

• A prospective cohort study involving 50 SAL patients and 50 control patients undergoing other aesthetic surgeries.
• Thromboelastography (TEG) was performed preoperatively, intraoperatively (mid and end), and postoperatively (60 min, 90 min, 24 hours).
• Standard pre- and postoperative coagulation studies were also conducted for all participants.

Main Results:

• Patients undergoing SAL exhibited significantly shorter R (clot formation time) and K (clot firming time) values compared to controls (P<0.001).
• SAL patients showed significantly greater Angle (fibrin growth and stranding) and MA (platelet function and clot strength) values (P<0.001).
• No patients in either group displayed abnormalities in standard pre- or postoperative coagulation studies.

Conclusions:

• TEG analysis indicates that SAL is associated with decreased initial clotting time and time to full clot formation.
• SAL patients demonstrate an increased pro-coagulability state and enhanced clot rigidity.
• Clot lysis time did not differ significantly between the SAL and control groups.
