The Resuscitation Council UK (RCUK) will emphasize the need to exclude major bleeding as the cause of collapse before giving fibrinolytic drugs for suspected PE in pregnancy. They will review and update the next print run of the RCUK Advanced Life Support Manual, teaching materials on the ALS course concerning pregnancy, and the Obstetric Cardiac Arrest Quick Reference Handbook.

1. The RCUK updates its guidelines on a regular basis using a process that is accredited by the National Institute for Health and Care Excellence (NICE). The most recent update was in May 2021. With regards the use of sonography (ultrasound is the mare common\y used term), the \atest 202--\. the RCUK guidelines include:
a. A greater emphasis on the use of ultrasound during Advanced life Support (ALS) to identify and treat reversible causes of cardiac arrest 1rus appUe.~ ID a\\. cardi.ac:. ;yews ~~j_-11-,;;,\. for the pregnant patient.

Focused ultrasound by a skilled operator can be used to identify reversible causes and may also be used to assess if a fetal heart rate is present.• See https://www.resus. orq. uk/library/2021-resuscitation-qu idel ines/special-ci rcumstances g uidel ines
2. The RCUK Advanced Life Support Manual (8th Edition, May 2021) includes the following regarding haemorrhage: Reversible causes of collapse and cardiac arrest in pregna1ncy Look for reversible causes using the 4 Hs and 4 T s approach. Abdominal ultrasound by a skilled operator to detect possible causes during cardiac arrest can be! useful. 1t can also permit an evaluation of feta/ viability, multiple gestations {twins) and plaCEmtal localisation. nshou1d not however delay treatments. Specific reversible causes of collapse or cardiac arrest in pregnancy include: Haemorrhage This can occur both antenatally and postnatatly. Causes include ectopic pregnancy, placental abruption, placenta praevia, abnormal placentation {incretal percreta) and uterine rupture. Maternity units should have a massive haemorrhage protocol. Treatment is based on the ABCDE approach. The key step is to stop the bleeding.
3. RCUK Advanced Life Support Manual {8th Edition, May 2021) includes the following regarding pulmonary embolism in pregnancy: Pulmonary embolism Pulmonary embolism causing cardiopulmonary collapse can present throughout pregnancy . CPR is started with modifications as necessary. The use of fibrinolytic therapy needs considerable thought, particularly if a peri-mortem caesarean section is beintJ considered {see below). If the diagnosis is suspected and maternal cardiac output cannot be restored it should be given.
4. The RCUK ALS subcommittee's opinion is that the issues raised '.Dy the MBBRACE report and the Inquest are addressed in the most recent RCUK guidance and teaching materials. Speciflca\\y: resus.org.uk 5th IFloor, Tavistock House North enquiries@resus.org.uk Tavistock Square, London WClH 9HR

a. Firstly, RCUK is mindful that its guidelines address allcardiac arces~arnHna'i..ma\ema\ cardiac arrests make up a very small proportion these arrests. \n addition the specia\ist skins and equipment required for ultrasound during resuscitation are not a\ways immediate\y available in all settings. Any changes therefore need to be proportionate and recognise t'ne risks of delaying time critical treatments such as flbrino\ysis "in patients with a suspected PE.
b. Active major bleeding (haemorrhage) is a contraindication for thrombolytic {frbrino\ytic) drugs regardless of the cause of bleeding or the patient group. This risk of bleeding with fibrinolytic drugs (which dissolve clots and prevent clotting) shou\d a\ready be known to those who use them. The section of the RCUK Advanced tife SapportManua~ tath E<:Mi'arr, Ma,r2fl~1ns'ls contraindications to fibrinolytic therapy - active internal bleeding is an absolute contraindication.
c. In addition to an ectopic pregnancy, there are a number of causes of co\\apse from b\eeding in the pregnant patient and these are highlighted in the current teaching materials.
d. There is already a strong emphasis on the use of u\trasound to look for reversible causes including haemorrhage in RCUK guidelines and teachin9- ma~-er1a\.c;, ror B\\. cau~s... ~~4:~ arrest including cardiac arrest during pregnancy.
5. To address the variance with the MBRRACE UK 2019 guidance, RCUK will further emphasise the need to exclude major bleeding as the cause of collapse before giving iibrino\ytic drugs tor suspected PE in pregnancy. We will also consider other teaming from this case. "The following areas wll'I 'oe reviewed and updated as necessary:
a. Next print run of RCUK Advanced Life Support Manua\ (8th Edition, May 2021).
b. Teaching materials on the ALS course concemlng pregrrancy.
