Ultrasound-guided Paravertebral Nerve Block For Laparoscopic Radical Gastrectomy

OBJECTIVE: To investigate the clinical value of ultrasound-guided paravertebral nerve block for patients undergoing laparoscopic radical gastrectomy.METHODS: Forty patients(ASA I to III)undergoing elective laparosc opic radical gastrectomy for gastric cancer,were randomly divided into t wo groups: general anesthesia group(group G)and general anesthesia com bined with paravertebral nerve block group(Group P).Patients in group P r eceived paravertebral injection of 0.375% ropivacaine.Recorded the blood pressure(BP),heart rate(HR)in different moments.Group P recorded th e range of block plane,the range of spinal nerve block and VAS score d uring recovery room(resting and cough).The amount of propofol and remi fentanil used was recorded,the relate complications,operation time and Ext ubation time were recorded as well.RESULTS:The amount of propofol and remifentanil used were lower in group G.The extubation time of Group P was lower in group P.At T1,T3,and T5,there was no statistical difference between the data;T4 and T6 data were statistically significant;the SBP and HR at T2 had statistically significant differences.There were 3 patients with nausea and vomiting in Group G,1 patient in group P.There was no poisoning with local anesthetic and puncture complications.CONCLUSIONS:Ultrasound-guided paravertebral nerve block is safe and effective for laparoscopic radical gastrectomy.It can shorten the extubation time,reduce the use of general anesthetic drugs,and make the hemodynamics more stabler.
