Multicenter Study Observational Study
Ultrasound-guided intermediate cervical plexus block for carotid endarterectomy using a new anterior approach: a two-centre prospective observational study.
The aim of this prospective, double-centre, observational study performed in 116 patients was to describe a new anterior approach of ultrasound-guided intermediate cervical plexus block for carotid endarterectomy. The median (IQR [range]) volume of ropivacaine 0.5% administered was 30 (25-30 [20-45]) ml. Supplemental local anaesthesia (infiltration and topical) was needed in 66 (57%) patients. ⋯ Adverse effects were of short duration and did not affect surgery. Satisfaction scores were high for 92 (79%) patients (63 satisfied; 29 very satisfied) and 104 (90%) surgeons (51 satisfied; 53 very satisfied). This study shows that the ultrasound-guided intermediate cervical plexus block using an anterior approach is feasible and provides similar results to other regional techniques during carotid endarterectomy.

Randomized Controlled Trial Comparative Study
Fibreoptic vs videolaryngoscopic (C-MAC(®) D-BLADE) nasal awake intubation under local anaesthesia.
Numerous indirect laryngoscopes have been introduced into clinical practice and their use for tracheal intubation under local anaesthesia has been described. However, a study comparing indirect laryngoscopic vs fibreoptic intubation under local anaesthesia and sedation appears lacking. Therefore, we evaluated both techniques in 100 patients with an anticipated difficult nasal intubation time for intubation the primary outcome. ⋯ The median (IQR [range]) time for intubation was significantly shorter with the videolaryngoscope with 38 (24-65 [11-420]) s vs 94 (48-323 [19-1020]) s (p < 0.0001). There was no difference in the success rate of intubation (96% for both techniques; p > 0.9999) and satisfaction of the anaesthetists and patients. We conclude that in anticipated difficult nasal intubation a videolaryngoscope represents an acceptable alternative to fibreoptic intubation.

Multicenter Study
Sedation practice in six acute hospitals - a snapshot survey.
The number of UK hospital patients receiving procedural sedation remains unknown. Our trainee research network recorded all procedural sedation given over a 48-h period at six acute hospitals in the South West of England. Three hundred and sixty patients aged between 1 and 96 years old were sedated. ⋯ The most frequent sedative combination was midazolam and fentanyl, with median (IQR [range]) doses of 2 (2-3 [1-10]) mg and 50 (50-100 [10-300]) μg used, respectively. We tested a methodology that could be used in a UK-wide denominator survey to describe sedation practice across the NHS. A national audit collecting serious adverse outcomes of sedation (severe harm or death) could then identify hotspots of sedation risk (clinical areas, patient groups, procedures and sedation techniques) where consistent application of current and improved standards might reduce harm.
