Randomized Controlled TrialEffect of adductor-canal-blockade on established, severe post-operative pain after total knee arthroplasty: a randomised study.
In this proof-of-concept study, we investigated the effect of the predominantly sensory adductor-canal-blockade on established pain in the early post-operative period after total knee arthroplasty (TKA). We hypothesised that the adductor-canal-blockade would reduce pain during flexion of the knee (primary end point) and at rest, as well as reducing morphine consumption and morphine-related side effects (secondary outcomes) compared with placebo. ⋯ This proof-of-concept study shows promising results regarding the analgesic efficacy of adductor-canal-blockade in post-operative pain treatment after TKA, with a significant reduction in pain during flexion of the knee in the early post-operative period compared with placebo. However, the study was not sufficiently powered to permit final conclusions.

Randomized Controlled TrialEarly removal of urinary catheter leads to greater post-void residuals in patients with thoracic epidural.
A recent study showed that the removal of a bladder catheter is safe in presence of thoracic epidural analgesia (TEA). However, the ability to void satisfactorily can be affected. The aim of this investigation is to determine whether patients with TEA are able to recover the micturition process. ⋯ In the presence of TEA, the removal of the bladder catheter on the morning after surgery leads to a transient impairment of the lower urinary tract function with no need for re-catheterisation.
