Objective: To investigate the clinical effects of phlegm and phlegm and magnesium sulfate combined with magnesium sulfate in sea lice in Qinhuangdao City. Methods: A total of 78 patients with sea lice in Qinhuangdao City from June to
May 2018 were enrolled. They were randomly divided into control group (n=39 cases) and observation group (n=39 cases). The control group was treated with magnesium sulfate. The observation group was treated with Qibai Colshi Decoction on the basisof the control group. The effect of the patients was evaluated after 5 days of treatment. The disappearance time of symptoms, inflammatory factors and adverse drug reactions were compared. Results: After treatment, the onset, pain time, skin loss, swelling time and course of treatment were shorter in the observation group than in the control group (P<0.05). The levels of inflammatory factors were lower than those before treatment (P<5). The levels of TNF-a, IL-6, HIS and 5-HT in the observation group were lower than those in the control group (P<0.05). The rash, itching, drug allergy, liver and kidney were observed in the observation group and the control group. There was no significant difference in the incidence of dysfunction and blood pressure (P>0.05). Conclusion: The combination of magnesium sulfate and magnesium sulfate in the treatment of sea lice in Qinhuangdao City can shorten the disappearance of symptoms, reduce the level of inflammatory factors, and increase the incidence of adverse drug reactions.
