Renal failure affects the pharmacology of nondepolarizing neuromuscular blockers making recovery of neuromuscular function unpredictable. Sugammadex antagonises rocuronium-induced neuromuscular blockade by encapsulating rocuronium, creating a stable complex molecule that is mainly excreted by the kidneys. Previous studies suggest that sugammadex is effective in reversing moderate neuromuscular block in the presence of renal failure, but no data are available regarding reversal of profound neuromuscular block in patients with renal failure. ⋯ In patients with renal failure, sugammadex (4 mg kg) effectively and safely reversed profound rocuronium induced neuromuscular block, but the recovery was slower than healthy patients.

Several previous studies using univariate analysis have suggested that the pre-anaesthetic train-of-four (TOF) ratio, concentration of anti-acetylcholine receptor (AChR) antibodies and the presence of preoperative generalised muscular involvement are determinants of an increased response to neuromuscular blocking agents (NMBAs) in patients with myasthenia gravis. However, the determinants of the response of patients with myasthenia gravis to rocuronium, which is expected to be used more frequently since the advent of sugammadex, have not been studied. ⋯ Multivariate analysis identified baseline TOF ratio and age of disease onset as determinants of the increased response to rocuronium in patients with myasthenia gravis.

The prevalence of chronic postsurgical pain (CPSP) is a critical medical problem with economic implications. Its prevalence after gastrointestinal surgery is not well documented, particularly when a laparoscopic approach is used. ⋯ The incidence of CPSP after laparoscopic colorectal surgery (17%) is similar to those reported in the literature after laparotomy. Risk factors are redo surgery for postoperative peritonitis, IBD and preoperative pain.

Multicenter Study Observational Study
Chronic postsurgical pain in Europe: An observational study.
Chronic postsurgical pain (CPSP) is an important clinical problem. Prospective studies of the incidence, characteristics and risk factors of CPSP are needed. ⋯ The collection of data on CPSP was feasible within the European registry PAIN OUT. The incidence of moderate to severe CPSP at 12 months was 11.8%. Functional impairment was associated with CPSP severity and neuropathic characteristics. Risk factors for CPSP in the present study were chronic preoperative pain, orthopaedic surgery and percentage of time in severe pain on D1.
