Current practice guidelines by the ACCP recommend that for patients undergoing inpatient framgin surgery, higher doses of LMWH or low-dose UFH be used rather than the usual doses used for nonobese fragmin dosing in obese patients have and suggest that the use of weight-based dosing of LMWH prophylaxis should be considered [ 63 ]. UFH has poor plasma recovery [ 30 ] and inconsistent pharmacokinetics. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide.
