[Effects of injection on intrapulmonary shunt and blood IL-6 and TNF-α levels during single lung ventilation in patients undergoing radical resection of esophageal cancer].

OBJECTIVE

To explore the effects of Rhodiola rosea injection on pulmonary shunt and serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels during single lung ventilation in patients undergoing radical resection of esophageal cancer.

METHODS

Forty-six patients undergoing radical operation for esophageal cancer were randomized equally into control group and Rhodiola rosea injection group. In the Rhodiola group, 10 mL of Rhodiola rosea injection was added into 250 mL of normal saline or 5% glucose solution for slow intravenous infusion, and normal saline of the same volume was used in the control group after the patients entered the operation room. At T, T and T, PaO of the patient was recorded and 2 mL of deep venous blood was collected for determination of serum TNF-α and IL-6 levels. The incidence of postoperative atelectasis of the patients was recorded.

RESULTS

Compared with those in the control group, the patients receiving Rhodiola rosea injection had significantly higher PaO and Qs/Qt at T and T (<0.05) and lower serum IL-6 and TNF-α levels at T (<0.05). No significant difference in the incidence of postoperative atelectasis was observed between the two groups (>0.05).

CONCLUSION

Rhodiola rosea injection before anesthesia induction can reduce intrapulmonary shunt during single lung ventilation, improve oxygenation, reduce serum IL-6 and TNF-α levels, and alleviate intraoperative lung injury in patients undergoing radical resection of esophageal cancer.
