The volume of blood lost during liver resection correlates with the CVP. Lowering the CVP to less than 5 cmH2O is a simple and effective way to reduce blood loss during liver surgery.
Twenty‐five patients having a major liver resection at the austin hospital were reviewed, 18 of whom had their operation after 1986. The indications were for melastatic disease in 14, hydatid in six and primary tumour in five. There were no operative deaths. Dissection was performed with the cavitron ultrasound surgical aspirator (cusa) and peroperative ultrasound used in 18 and without in seven. Mean blood loss was 1.75 u in the cusa group and 6.5 u in the non‐cusa group (p > 0.05). It is concluded that inlraoperalive ultrasound and use of the cusa makes major liver resection a more precise and less hazardous procedure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
