Uterotonics play an important role in the management of postpartum haemorrhage (PPH), often caused by uterine atony. The World Health Organization (WHO) recommends the application of uterotonics for all births. Oxytocin, considered the first-line uterotonic, binds to a G protein-coupled receptor which is subject to down sensitization upon repeated or prolonged administration of oxytocin. ⋯ Methylergometrine and carboprost should, therefore, be avoided in many cardiovascular pathologies. Carbetocin is a chemical modification of oxytocin with a longer half-time, and therefore one bolus of carbetocin is usually sufficient. Its heat stability makes it an ideal candidate in resource-restricted settings.

Maternal sepsis is a life-threatening condition defined as organ dysfunction resulting from infection that can arise during pregnancy, childbirth, postabortion, or in the postpartum period. Validated diagnostic criteria of maternal sepsis and septic shock may reduce the impact of this condition on maternal health worldwide, but the lack of consensus on adequate tools due to the overlap between physiological adaptations that occur during pregnancy and signs and symptoms of infection and sepsis can delay both diagnosis and treatment. ⋯ Interventions within the first hour from diagnosis have been proposed in 2021 to emphasize the state of emergency of a maternal sepsis. This review will highlight the utility of standardized diagnostic criteria, the implemented approaches for the prevention and treatment of maternal infections, and the strategies for early management of critically ill parturients.

ReviewNeuraxial labor analgesia: is there a place for neuraxial adjuvants beyond opioids.
Neuraxial labor analgesia is considered the gold standard technique for analgesia. Ideally, a good neuraxial technique uses dilute local anesthetic solutions to produce effective pain relief with no or minimal motor impairment. Adjuvant drugs that are co-administered with the local anesthetic either epidurally or intrathecally are useful in achieving this goal. The current review focuses on the effectivity and side-effect profile of various commonly used or tested adjuvants.

Leading causes of intensive care unit (ICU) admission include hemorrhage, hypertensive disorders of pregnancy, and sepsis. Although the incidence of ICU admission in pregnancy may be low, this does not account for critical illness in labor and delivery or maternity unit suites, which is as high as 1-3%. ⋯ Recently, comorbidity-based screening tools, which quantify a patient's medical comorbidity burden, have been developed and validated in predicting ICU admission and death. Noninvasive ultrasonography such as point-of-care ultrasonography becomes essential in determining hemodynamic status, guides resuscitation, and manages cardiovascular dysfunction.
