Efficacy of Intrathecal Oxytocin to Speed Recovery After Hip Surgery
Efficacy of Intrathecal Oxytocin to Speed Recovery After Hip Surgery
The purpose of this study is to determine the effect of intrathecal oxytocin on speed of
 reduction in pain for the first 60 days after hip surgery.
This is a single-center, NIH funded clinical study at Wake Forest Baptist Medical Center. The
 investigators anticipate that intrathecal oxytocin will speed recovery from pain after major
 surgery (hip arthroplasty). For this study, the investigators will use a randomized,
 controlled and blinded study of intrathecal oxytocin in patients scheduled for hip
 arthroplasty, with primary outcome being the slope of change in pain over the first 60 days
 following surgery, using growth curve modeling and a ln(time) function.
