Randomized Controlled Trial Comparative StudyA randomised comparison of C-MAC™ and King Vision® videolaryngoscopes with direct laryngoscopy in 180 obstetric patients.
Current evidence suggests that there is uncertainty about which videolaryngoscope performs best in obstetric anaesthesia. The aim of this study was to compare C-MAC and King Vision® videolaryngoscopes and direct laryngoscopy for tracheal intubation of patients undergoing caesarean section. ⋯ Compared to direct laryngoscopy, C-MAC and King Vision® did not prolong the time to intubation, supporting these videolaryngoscopes as primary intubation devices in obstetric anaesthesia. The C-MAC was easier to use and needed fewer additional manoeuvres than the King Vision®. The C-MAC may be better suited for tracheal intubation of obstetric patients undergoing caesarean section.

Comparative StudyThe comparative accuracy of a handheld and console ultrasound device for neuraxial depth and landmark assessment.
The study aimed to compare the accuracy of epidural depth estimation of a handheld ultrasound device, with an integrated algorithm that estimates epidural depth (AU; Accuro, Rivanna Medical), to that of a console ultrasound machine (GU; GE LOGICTM S8). ⋯ The AU and GU provided comparable epidural depth estimates. The AU device may be a reasonable alternative to more sophisticated ultrasound devices in determining the epidural space and depth in a non-obese obstetric population.

Case ReportsHepatic adenoma during pregnancy and anesthetic management.
We report the case of a 24-year-old woman with a large hepatic adenoma diagnosed in the third trimester of pregnancy. The adenoma was at risk of rupture. She underwent scheduled preterm cesarean delivery under combined spinal-epidural anesthesia, followed by transarterial embolization on post-partum day six. Definitive resection of the adenoma took place two months postpartum.

Design errors in vital sign charts used in consultant-led maternity units in the United Kingdom.
Paper-based charts remain the principal means of documenting the vital signs of hospitalised pregnant and postnatal women. However, poor chart design may contribute to both incorrect charting of data and clinical responses. We decided to identify design faults that might have an adverse clinical impact. ⋯ We recommend the urgent development of an evidence-based, standardised obstetric observation chart, which integrates 'human factors' and user experience. It should have a clear layout and style, appropriate colour scheme, correct language and labelling, and the ability for vital signs to be documented accurately and quickly. It should incorporate a suitable early warning score to guide clinical management.

Case ReportsMaternal respiratory distress and successful reversal with sugammadex during intrauterine transfusion with fetal paralysis.
A 70 kg, 34-year-old woman at 29 weeks-of-gestation required intrauterine transfusion for Rh (D) alloimmunization. In the ambulatory treatment clinic, 19 mg of rocuronium was administered intramuscularly in split doses into the fetal buttock. ⋯ Sugammadex 100 mg was administered intravenously and complete resolution of neuromuscular blockade was demonstrated using a Neuromuscular Transmission™ monitor. When neuromuscular blocking agents are administered in ambulatory settings, management protocols, reversal agents, and skilled assistance should be immediately available for managing potentially life-threatening complications.
