Application of goal-directed pulse pressure variation combined with low central venous pressure technique in liver surgery
To explore the application of goal-directed fluid therapy based on pulse pressure variation rate (PPV) combined with low central venous pressure (LCVP) technique in liver surgery.
Methods
2
A total of 86 patients who underwent liver lobe/segment resection in our hospital from January 2022 to December 2023 were included,and randomly divided into two groups by random sequence method. Patients in the conventional group were treated with LCVP technique,while patients in the test group were given PPV goal-directed intervention on the basis of the conventional group. The surgical indicators,hemodynamic indicators,cognitive function,adverse reactions and recovery of gastrointestinal function of patients in the two groups were compared.
Results
2
There was no statistically significant difference in the operation time,Pringle maneuver time,first postoperative exhausting time or first postoperative defecation time of patients between the two groups(
P
>
0.05). However,the intraoperative blood loss,intraoperative fluid infusion volume and hospital stay of patients in the test group were all less/shorter than those in the conventional group (
P
<
0.05). Compared with the time point of T0,patients in the two groups showed increased heart rate (HR) but decreased mean arterial pressure (MAP) and central venous pressure (CVP)at time points of T1 and T2 (
P
<
0.05). There was no statistically significant difference in the HR or MAP of patients between the two groups at time points of T0,T1,T2 and T3 (
P
>
0.05).At time points of T1 and T2,the CVP of patients in the test group was lower than that in the conventional group (
P
<
0.05). One day after operation,the mini-mental state examination (MMSE) score of patients in the test group was higher than that in the conventional group (
P
<
0.05). The MMSE scores 7 days after operation of patients in the two groups were higher than those 1 day after operation (
P
<
0.05). Patients in the test group had a lower total incidence of adverse reactions and a shorter recovery time of gastrointestinal function than those in the conventional group (
P
<
0.05).
Conclusion
2
The goal-directed fluid therapy based on PPV combined with LCVP technique has a good application effect in liver surgery,which can reduce intraoperative blood loss and fluid infusion volume of patients,shorten hospital stay,increase hemodynamic stability,improve postoperative cognitive dysfunction,and promote the recovery of gastrointestinal function,with a relatively high treatment safety.
