Summary: The 7th National Audit Project of the Royal College of Anaesthetists studied peri‐operative cardiac arrest in the UK. We report the results of the vascular surgery cohort from the 12‐month case registry, from 16 June 2021 to 15 June 2022. Anaesthesia for vascular surgery accounted for 2% of UK anaesthetic caseload and included 69 (8%) reported peri‐operative cardiac arrests, giving an estimated incidence of 1 in 670 vascular anaesthetics (95%CI 1 in 520–830). The high‐risk nature of the vascular population is reflected by the proportion of patients who were ASA physical status 4 (30, 43%) or 5 (19, 28%); the age of patients (80% aged > 65 y); and that most cardiac arrests (57, 83%) occurred during non‐elective surgery. The most common vascular surgical procedures among patients who had a cardiac arrest were: aortic surgery (38, 55%); lower‐limb revascularisation (13, 19%); and lower‐limb amputation (8, 12%). Among patients having vascular surgery and who had a cardiac arrest, 28 (41%) presented with a ruptured abdominal aortic aneurysm. There were 48 (70%) patients who had died at the time of reporting to NAP7 and 11 (16%) were still in hospital, signifying poorer outcomes compared with the non‐vascular surgical cohort. The most common cause of cardiac arrest was major haemorrhage (39, 57%), but multiple other causes reflected the critical illness of the patients and the complexity of surgery. This is the first analysis of the incidence, management and outcomes of peri‐operative cardiac arrest during vascular anaesthesia in the UK. [ABSTRACT FROM AUTHOR]

The article presents a medical study which explores the significance of cardiopulmonary exercise testing (CPET) in forecasting mortality following elective open abdominal aortic aneurysm (AAA) repair in Great Britain. It determines the relationship among CPET variables, revised cardiac risk index (RCRI), and modified customised probability index (MCPI). Moreover, it suggests the need for robust pre-operative assessment in patients presenting for endovascular aneurysm repair (EVAR).

The article reports on the introduction of medical guideline against endovascular repair of ruptured abdominal aortic aneurysms (REVAR) to decrease surgical time and increase pre-operative fluid resuscitation in Great Britain. It notes that the medical group performed a second loop audit in adherence to the new guideline. It mentions that the new guideline improves patient's health outcome.
