Effects of manual and syringe pump induction of total intravenous anaesthesia on propofol waste: a single-centre retrospective analysis.

Background: Propofol accounts for a substantial proportion of medication waste. Evidence-based waste reduction methods are scarce.

Methods: In a retrospective analysis of 331 procedures, the total propofol waste per surgery was compared between manual and syringe pump induction of anaesthesia during total intravenous anaesthesia (TIVA), with a syringe pump used to maintain TIVA after induction.

Rupture of renal artery aneurysm during late pregnancy: clinical features and diagnosis.

Purpose: Rupture of renal artery aneurysm during pregnancy is a severe complication with high mortality and morbidity for mother and fetus, and diagnosis is difficult. The clinical presentation is easily confused with more common conditions like placental abruption, and most of the cases are diagnosed with timely delay.

Methods: We present the case of a patient with spontaneous rupture of an aneurysm of the left renal artery during late pregnancy and summarize the previous reports of ruptured renal artery aneurysm during pregnancy and early postpartum period.
