Abstract:
Objective To investigate the effects of different methods of volume therapy on the inflammatory response in patients undergoing liver cancer resection.Methods Forty ASA Ⅰ or Ⅱ patients,aged 40-60 yr,with body mass index 20-25 kg/m2,undergoing liver cancer resection,were randomly divided into 2 groups ( n =20 each):routine fluid replacement group (group Ⅰ ) and goal-directed fluid replacement group (group Ⅱ ).The fluid replacement regime in group Ⅰ =compensatory volume expansion (CVE) + physiological requirements + cumulative loss + confinued loss + the third space losses.CVE was replaced with lactated Ringer's (LR) solution 5 mg/kg before anesthesia induction.The physiological requirements and cumulative loss were replaced with LR solution according to the principle of 4-2-1.The continued loss equal to the intraoperative blood loss was replaced with the equal volume of 6％ hydroxyethyl s tarch ( HES 130/0.4).The 3rd space losses were replaced with LR solution 5 ml·kg-1 ·h-1.In group Ⅱ,CVE was replaced with LR sol6ution as in group Ⅰ.LR solution was infused after anesthesia induction at 5 ml·kg-1 ·h-1.6％ HES was infused to maintain left ventricular ejection time (LVETc) between 350-400 ms.When 350 ms ＜ LVETc ＜ 400 ms and the amplitude of stroke volume ( SV ) increased by ＞ 10％,6％ HES was infused continuously until the amplitude of SV increased by ≤ 10％.Blood samples were taken before anesthesia induction and at the end of operation for measurement of serum TNF-α,IL-2,IL-4,IL-6 and IL-8 concentrations.The adverse cardiovascular reactions were recorded.Results Compared with group Ⅰ,the serum TNF-α,IL-6,IL-8 concentrations were significantly decreased,the serum IL-2 and IL-4 concentrations were significantly increase,and the incidence of hypotension and tachycardia was significantly decreased in group Ⅱ ( P ＜ 0.05).No adverse cardiovascular reactions were found in both groups.Conclusion LVETc and SV-guided volume therapy can maintain the blood volume and inhibit the inflammatory response and is suitable for the patients undergoing liver cancer resection.
