Effect of stellate ganglion block guided by ultrasound on the pain, immunity and antioxidant capacity after head and face surgery

ObjectiveTo investigate the effects of stellate ganglion block guided by ultrasound on pain, immunity and antioxidant capacity after head and face surgery.

MethodsEighty patients treated with craniofacial surgery were randomly divided into the observation group and control group(40 cases each group).The observation group was treated with right stellate ganglion block guided by ultrasound before anesthesia induction, while the control group was treated routine general anesthesia.The changes of pain digital scores at different times after operation were compared between two groups.The time of self-eating, getting out of bed and hospitalization in two groups after operation were analyzed, and the immune function, antioxidant ability and complications 48 h after operation were compared between two groups.

ResultsThe differences of the pain digital score between two groups at different times were statistically significant after operation(P < 0.01).The pain digital scores in two groups at different time-points decreased, and which in observation group was lower than that in control group(P < 0.01).The pain scores in two groups showed a decreasing trend with time going on(P < 0.01).The time of postoperative self-eating and getting out of bed in observation group were earlier than those in control group, and the time of hospitalization after operation was shorter than that in control group(P < 0.01).The levels of IgA, IgG and SOD in observation group were higher than those in control group after 48 h of operation, and the level of MDA of antioxidant capacity index in observation group was lower than that in control group(P < 0.01).The total incidence rate of tachycardia, anesthesia recovery delay, postoperative hemorrhage and postoperative infection in observation group was lower than that in control group(P < 0.01).

ConclusionFor patients treated with head and face surgery, the right stellate ganglion block guided by ultrasound can effectively relieve the postoperative pain, improve the body immunity and antioxidant capacity, and reduce complications.
