The International Committee of Medical Journal Editors recommends the prospective registration of interventional clinical trials. We aimed to assess the compliance with these guidelines for manuscripts submitted to and published by a single anaesthetic journal. We examined the rates of prospective trial registration, the incidence of discrepancies in primary outcome measure(s) and sample sizes, and the citation metrics of all randomised controlled trials published in Anaesthesia over a 3-year period (2014-2016). ⋯ There was no difference in the median (IQR [range]) number of citations per month since publication between prospectively (0.27 (0.15-0.46 [0.00-1.59]), and retrospectively (0.39 (0.15-0.62 [0.10-0.67]); p = 0.502) or unregistered (0.33 (0.10-0.52 [0.00-0.67]); p = 0.867) studies. Our results suggest that prospective clinical trial registration has no influence on acceptance for publication by Anaesthesia or subsequent citation metrics. The international recommendation for prospective trial registration appears to have not been universally incorporated into anaesthetic-related research practice.

Throat packs are commonly inserted by anaesthetists after induction of anaesthesia for dental, maxillofacial, nasal or upper airway surgery. However, the evidence supporting this practice as routine is unclear, especially in the light of accidentally retained throat packs which constitute 'Never Events' as defined by NHS England. On behalf of three relevant national organisations, we therefore conducted a systematic review and literature search to assess the evidence base for benefit, and also the extent and severity of complications associated with throat pack use. ⋯ Instead, there were many reports of minor and major complications (the latter including serious postoperative airway obstruction and at least one death), and many descriptions of how to avoid complications. As a result of these findings, the three national organisations no longer recommend the routine insertion of throat packs by anaesthetists but advise caution and careful consideration. Two protocols for pack insertion are presented, should their use be judged necessary.
