Association of diastolic blood pressure with survival during paediatric cardiopulmonary resuscitation

AIM: To examine the relationship between survival and diastolic blood pressure (DBP) throughout resuscitation from paediatric asphyxial cardiac arrest. METHODS: Retrospective, secondary analysis of 200 swine resuscitations. Swine underwent asphyxial cardiac arrest and were resuscitated with predefined periods of basic and advanced life support (BLS and ALS, respectively). DBP was recorded every 30 s. Survival was defined as 20-min sustained return of spontaneous circulation (ROSC). RESULTS: During BLS, DBP peaked between 1–3 min and was greater in survivors (20.0 [11.3, 33.3] mmHg) than in non-survivors (5.0 [1.0, 10.0] mmHg; p
