ReviewAllergic reactions during labour analgesia and caesarean section anaesthesia.
Allergic reactions in the parturient are challenging for the anaesthetist who is dealing with both mother and baby, often in circumstances when there is a need for delivery. While most previous reviews have focused on specific substances in individual cases, this review focuses on allergic reactions during the peripartum period, the differential diagnosis and specific treatment options. Immunoregulation and susceptibility to allergic reactions may change during pregnancy. ⋯ Most drugs used for resuscitation of the non-pregnant patient are suitable for the parturient. Some substances, such as H2-receptor antagonists for aspiration prophylaxis or corticosteroids for prematurity, may have been given before the event. Although fetal outcome is important, the mother is the primary focus of care.

Parturients with renal insufficiency or failure present a significant challenge for the anesthesiologist. Impaired renal function compromises fertility and increases both maternal and fetal morbidity and mortality. Close communication amongst medical specialists, including nephrologists, obstetricians, neonatologists and anesthesiologists is required to ensure the safety of mother and child. ⋯ Kidney function may deteriorate during pregnancy, necessitating early intervention. The goal is to maintain hemodynamic and physiologic stability while the demands of the pregnancy change. Drugs that may adversely affect the fetus, are nephrotoxic or are dependent on renal elimination should be avoided.
