ABSTRACT
Objective To evaluate the accuracy of ultrasound-measured inferior vena cava (IVC) diameter in assessment of the preoperative blood volume in elderly patients.Methods Sixty patients,aged 60-75 yr,with body mass index 20-25 kg/m2,of ASA physical status Ⅰ-Ⅲ,scheduled for elective transurethral resection of prostate,were randomly divided into 3 groups (n =20 each)control group (group C),lactated Ringer's solution group (group RL),and hydroxyethyl starch group (group H).Lactated Ringer's solution 8 ml/kg was infused intravenously in group RL.Hydroxyethyl starch 130/0.4 8 ml/kg was infused intravenously in group H.SpO2,mean arterial pressure (MAP),HR and central venous pressure (CVP) were monitored before and after fluid therapy.The IVC diameters,both during expiration (IVCe) and inspiration (IVCi),were measured using ultrasound.IVC collapsibility index (IVC-CI) was calculated.Results The IVCeand IVCi were significantly increased,and IVC-CI was decreased after fluid therapy as compared with those before fluid therapy in RL and H groups.Compared with group C,the IVCe and IVCi were significantly increased,and IVC-CI was decreased after fluid therapy in RL and H groups.IVCe and IVCi were positively correlatedwith CVP (r=0.746 and 0.697,respectively).IVC-CI was negatively correlated with CVP (r =-0.547).Conclusion Ultrasoundmeasured IVC diameter provides better accuracy in assessing the preoperative blood volume in elderly patients.
