Summary
A recent audit of quality of recovery following hip replacement at Hollywood Hospital indicated that a proportion of patients experience significant pain in the 1st 24h following surgery. The aim of this study is to evaluate the efficacy a new nerve block termed the erector spinae block in reducing pain in the first 24h following hip replacement . A pilot audit of this nerve block technique in 33 patients at Hollywood found it to be safe and effective in reducing pain without any compromise to patient mobility.
