■中央视网膜动脉阻塞(CRAO)突然引起无痛的视力丧失,这通常是显着的。只有8%的自发性再灌注患者视力有意义的改善。如果在视网膜梗塞发生之前开始高压氧治疗(HBOT)被认为是有益的。海底和高压医学协会(UHMS)关于CRAO管理的指南于2019年进行了最后修订。这项调查向澳大利亚和新西兰(ANZ)的高压医学单位(HMU)询问了CRAO病例的发生率,并将其后续管理与UHMS指南进行了比较。
■通过SurveyMonkey®向所有12个处理紧急适应症的ANZHMU发送了一项匿名调查,允许关于他们对CRAO的管理的多项选择和自由文本答案。
■在过去五年中,ANZHMU治疗了146例CRAO。大多数(101/146)例(69%)最初是在284kPa的压力下治疗的。这是UHMS指南和ANZ实践之间在CRAO管理中发现的最大差异领域。
■很少有ANZHMU严格遵守UHMS准则。我们建议大多数ANZHMU使用的更简化的管理协议。
UNASSIGNED: Central retinal artery occlusion (CRAO) presents suddenly causing painless loss of vision that is often significant. Meaningful improvement in vision occurs in only 8% of patients with spontaneous reperfusion. Hyperbaric oxygen treatment (HBOT) is considered to be of benefit if commenced before retinal infarction occurs. The Undersea and Hyperbaric Medical Society (UHMS)
guidelines on the management of CRAO were last amended in 2019. This survey questioned Australian and New Zealand (ANZ) hyperbaric medicine units (HMUs) about the incidence of CRAO cases referred and compared their subsequent management against the UHMS
guidelines.
UNASSIGNED: An anonymous survey via SurveyMonkey® was sent to all 12 ANZ HMUs that treat emergency indications, allowing for multiple choice and free text answers regarding their management of CRAO.
UNASSIGNED: One-hundred and forty-six cases of CRAO were treated in ANZ HMUs over the last five years. Most (101/146) cases (69%) were initially treated at a pressure of 284 kPa. This was the area of greatest difference noted in CRAO management between the UHMS
guidelines and ANZ practice.
UNASSIGNED: Few ANZ HMUs strictly followed the UHMS
guidelines. We suggest a more simplified management protocol as used by the majority of ANZ HMUs.
