Observational StudyOcular ultrasonography for diagnosing increased intracranial pressure in patients with severe preeclampsia.
Ultrasound measurements of optic nerve sheath diameter (ONSD) and optic disc height (ODH) measured outside pregnancy correlate with intracranial hypertension. Data on the usefulness of ocular ultrasonography in preeclampsia are limited. ⋯ Severe preeclampsia was associated with a significantly higher ONSD and increased ODH, which could be ultrasonographic evidence of papilledema.

Case ReportsRepeated attacks of type III hereditary angioedema with factor XII mutation during pregnancy.
In type III hereditary angioedema (HAE type III), the phenotype is the same as type I and type II disease, but the level and function of C1-esterase inhibitor (C1-INH) is normal. Hereditary angioedema type III has been described as an oestrogen-sensitive form because it can be triggered or aggravated by exposure to high oestrogen levels as seen during pregnancy, especially when associated with Factor XII mutation. This case report describes the evolution and management of repeated angioedema attacks during pregnancy in a woman with HAE, with normal levels and function of C1-INH (type III); and a mis-sense mutation of factor XII. The physiopathology and genetic features, the unpredictability of clinical manifestations and the management during pregnancy and delivery are discussed.

Observational StudyClearsight™ use for haemodynamic monitoring during the third trimester of pregnancy - a validation study.
We assessed the validity of Clearsight™ as a non-invasive cardiac output and stroke volume monitoring device, comparing it with transthoracic echocardiography measurements during the third trimester of pregnancy. ⋯ The agreement between Clearsight™ and the echocardiography measurements of cardiac output and stroke volume were not within an acceptable range in the third trimester of pregnancy.

Case ReportsNew onset acute pulmonary edema after methylergonovine given during cesarean delivery of a patient with undiagnosed Raynaud's disease.
Raynaud's disease is a medical condition in which arterial spasm causes episodes of reduced blood flow, in the setting of certain triggers such as cold weather. Patients with this condition are at risk of adverse reactions if they receive medications with vasoactive properties. ⋯ However, pulmonary events have rarely been reported. We report our anesthetic management of a 36-year-old patient, with undiagnosed Raynaud's disease and undergoing cesarean delivery, who experienced new onset acute pulmonary edema after methylergonovine administration to manage postpartum hemorrhage.

Risk factors for post-dural puncture headache following injury of the dural membrane: a root-cause analysis and nested case-control study.
Post-dural puncture headache following trauma to the dural membrane during neuraxial anaesthesia occurs in 0.13-6.5% of pregnant patients. Identifying factors beyond individual performance that contribute to this adverse event is crucial to developing improvement strategies. ⋯ Post-dural puncture headache in this setting is not the result of the individual anaesthetist's characteristics alone. Additional factors including team composition, the presence of obstetrical perinatal pathology, and associated patient's conditions, are also associated with this event. Improvement strategies should consider all these factors.
