While this pattern of injury is typically associated with indirect trauma to the globe by a BB or a bullet, this is the first report of chorioretinitis sclopetaria precipitated by a high-velocity liquid missile. Chorioretinitis sclopetaria is defined as a full-thickness chorioretinal disruption resulting from a high-velocity projectile passing adjacent to or into the orbit without penetrating the globe. Chorioretinal deformation and ocular comorbidities are influenced by the velocity of the missile and its spatial relationship to the orbit. While this pattern of injury is typically associated with indirect trauma to the globe by a BB or a bullet, this is the first report of chorioretinitis sclopetaria precipitated by a high-velocity liquid missile. Despite reported superior intubation outcomes associated with Parker Flex-Tip (PFT) tubes compared with those associated with standard polyvinylchloride tubes, the efficacy and safety of PFT tubes remain uncertain. To compare the intubation outcomes between PFT and conventional standard polyvinylchloride tubes. Meta-analysis of randomised controlled trials. Embase, Medline, Google Scholar, PubMed and the Cochrane controlled trials register from inception until 3 January 2021. All randomised trials comparing intubation outcomes between PFT (PFT group) and standard polyvinylchloride (standard polyvinylchloride group) tubes. Analysis of the 13 eligible trials showed no significant difference in successful first-attempt intubation rate [risk ratio (RR) 1.20, 95% confidence interval (CI) 0.99 to 1.44] (6 trials, 568 participants), trauma risk (RR 0.83, 95% CI 0.67 to 1.03) (5 trials, 501 participants) as well as the overall risks of epistaxis (RR 0.58, 95% CI 0.26 to 1.31) (3 trials, 262 participants),e other intubation outcomes associated
