Obstetric Medicine and Intensive Care: Maternal Critical Illness in Practice

Pregnant and postpartum women make up a small proportion of intensive care unit (ICU) admissions, but they require distinct, carefully adapted approaches to care. This review outlines these challenges and proposes general principles to address them, emphasising consultant-level multidisciplinary input and alignment with national standards for service organisation and escalation of care. Pregnancy-related physiological changes affect haemodynamics, ventilation, and renal function-all of which have implications for monitoring, treatment thresholds, and drug selection. The practical aspects of organ support are discussed, as well as imaging and contrast safety. It is emphasised that maternal stabilisation and timely critical diagnosis should take priority, and that pregnant women must not be disadvantaged in their access to life-saving interventions. The conditions that may lead to critical illness in obstetric patients are reviewed, with a discussion of the current evidence and clinical practice. Attention to psychological well-being and lactation support is underscored as an essential component of holistic recovery and long-term outcomes.
