1. Introduction Pregnancy-specific risk factors for ICU admission include preeclampsia, amniotic fluid embolism, tocolytic-associated pulmonary edema, and peripartum sepsis. Hormone-mediated shifts in type 1/type 2 T-helper cells lead to transient immunosuppression during pregnancy, particularly from weeks 13 to 27 [1]. This immunosuppression is characterized by reduced natural killer cells, T-helper cells, and T-cytotoxic cells, which increase susceptibility to viral and fungal pneumonias [1].

1. Introduction Aneurysmal subarachnoid haemorrhage (aSAH) is a severe subtype of stroke which may affect younger patients, and is marked by neurological and systemic complications that considerable influence morbidity and mortality rate. The mortality after aSAH is estimated at approximately 40%, with a 1.5-times elevated risk of post-survival fatality compared to the general population at the 12-month follow-up.
