Thoracic surgery for radical resection of lung tumor requires deep anesthesia which can lead to an adverse inflammatory response, loss of hemodynamic stability, and decreased immune function.
We evaluated the feasibility and benefits of ultrasound-guided paravertebral nerve block anesthesia in combination with general anesthesia for thoracic surgery for lung cancer.
This study aimed to evaluate the application of ultrasound-guided paravertebral nerve block anesthesia for lung cancer surgery to inform practice.
Patients in the control group received an epidural block combined with general anesthesia. For patients in the observation group, ultrasound-guided paravertebral nerve block anesthesia was used before induction of general anesthesia. The concentrations of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were determined by enzyme-linked immunosorbent assay, with the concentrations of epinephrine, norepinephrine, and dopamine determined by radio-immunity turbidimetry. The mean arterial pressure (MAP), heart rate (HR) and oxygen saturation (SpO2) were measured at baseline, before surgery and anesthesia, 15 min after anesthesia (T1), induction intubation, 5 min after skin incision and before extubation (T4) in both groups. The stress response and hemodynamic data were reported as a mean ± SD.
The use of intra-operative remifentanil and propofol and of postoperative sufentanil was significantly less in the observation than the control group. The MAP and HR at T1 through T4 were higher for the observation than control group. The postoperative levels of epinephrine, norepinephrine and dopamine were higher after surgery than at baseline for both groups. However, these levels were lower in the observation than control group at T1 through T4. The postoperative TNF-α and IL-6 levels after surgery were lower in the observation than in the control group. This difference in incidence rate of adverse reactions was not different.
Ultrasound-guided paravertebral nerve block anesthesia has good indication for lung cancer surgery, with little effect on patients’ stress and hemodynamic responses.
Large sample studies need to performed in the future.
