Factors Associated With Outcome after Superior Hypogastric Plexus Neurolysis in Cancer Patients.
Superior hypogastric plexus neurolysis (SHP-N) has been shown in uncontrolled studies to provide intermediate-term benefit in a majority of patients with pain secondary to genitourinary, gynecologic, and colorectal cancers. The purpose of this is to determine factors associated with treatment outcome. ⋯ Selecting patients based on demographic and clinical variables may improve treatment outcomes for SHP-N. Larger, prospective studies are needed to confirm our results and better refine selection criteria better.

Multicenter Study[Regional survey of peripheral nerve block practice by French residents.]
There are limited data on peripheral nerve block (PNB) practices by residents in France, especially with after introduction of ultrasound. A survey was conducted on PNB practices by French residents. ⋯ The majority of procedures performed by the residents are using ultrasound. The procedure is usually fast, requiring mainly a single puncture and has a high rate of success.

Randomized Controlled Trial Multicenter Study
Neuraxial block, death and serious cardiovascular morbidity in the POISE trial.
This post hoc analysis aimed to determine whether neuraxial block was associated with a composite of cardiovascular death, non-fatal myocardial infarction (MI) and non-fatal cardiac arrest within 30 days of randomization in POISE trial patients. ⋯ In patients at high risk of cardiovascular morbidity, neuraxial block was associated with an increased risk of adverse cardiovascular outcomes, which could be causal or because of residual confounding.

Multicenter Study Comparative StudyUltrasound guidance reduces the risk of local anesthetic systemic toxicity following peripheral nerve blockade.
The use of ultrasound for peripheral nerve blockade reduces the incidence of systemic local anesthetic toxicity by at least 65%, possibly 80%.

Multicenter Study
Comparison of subgluteal sciatic nerve block duration in type 2 diabetic and non-diabetic patients.
Although animal studies demonstrated delayed recovery after nerve block in laboratory models of diabetes, the duration of the action of sciatic nerve blocks clinically in patients with diabetes remains to be determined. We studied the duration of a sciatic nerve block in type 2 diabetic patients compared with non-diabetic patients. ⋯ These findings demonstrate that diabetic patients with pre-existing incipient neuropathy exhibit delayed recovery from the block with ropivacaine, confirming animal studies. Clinical trial registration ClinicalTrials.gov, NCT01704612.
