Abstract:
Objective To explore the effect of paravertebral nerve block for preemptive analgesia on patients with thoracic surgery,and provide reference for clinical anesthesia.Methods From March 2014 to February 2016,102 patients with thoracic surgery in our hospital were selected as the research object,and they were divided into the observation group and the control group with 51 cases in each group according to the anesthesia methods.All the patients were given total intravenous anesthesia.Patients of the control group were injected propofol 1~2 mg/kg,sufentanil 0.4~0.5 g/kg,midazolam 0.1 mg/kg and rocuronium 0.5~0.7 mg/kg,while patients of the observation group were injected ropivacaine(with concentration of 0.5%)5 mL,sufentanil 0.1~0.3 μg·kg-1·min-1 and propofol 6~8 mg·kg-1·min-1 as an addition with the use of ultrasound to guide the paravertebral nerve block.The effect of the two groups were compared.Results The dosage of propofol,remifentanil and rocuronium in the observation group were significantly lower than those in the control group during the operation.The VAS score,postoperative pulmonary complication rate,ICU rate,extubation time,postoperative recovery time at different time of observation group were significantly lower than those of the control group,and SpO2 was higher in control group 30 minutes after tracheal extubation, the differences were significant (P<0.05).Conclusion Paravertebral nerve block requires less dosage of anaesthetic, and it has more significant analgesia effect on patients with thoracic surgery, which can efficiently promote the recovery of patients.
