Opportunity of drainage removal after primary arthroplasty / 中国矫形外科杂志

ABSTRACT

Though lack of definite evidences,closed suction drainage after arthroplasty is routinely employed by the majority of orthopaedic surgeons with the aim of preventing the formation of wound haematoma,reducing delayed wound healing and the risk of deep infection.But the optimal time to remove drains is controversial.The usual time to remove drains is 48~72 h after operation when the volume of drains is less than 50ml within 24 h.But some scholars find that the time of draining more than 24 h increases the risk of wound infection.This paper reviews the literature of draining time,and concludes that the optimal time to remove drains is 24 h after the primary arthroplasty.
