OBJECTIVE： To introduce the pharmaceutical care for refractory mycoplasma pneumoniae （MP） pneumonia combined with cerebral infarction in child by clinical pharmacist， and to improve further understanding of MP-induced cerebral infarction and the management level of the clinical pharmacist. METHODS： Clinical pharmacist provided whole course pharmaceutical care for a child case of refractory PM pneumonia complicated with cerebral infarction admitted to the Children’s Hospital of Fudan University in Oct. 2018. The drug use in anti-infection， anti-inflammatory， treatment of cerebral infarction， possible drug interactions and suspected ADR were analyzed during treatment. RESULTS： The child admitted to the hospital for treatment due to MP pneumonia. During the treatment， the child suffered from cerebral infarction symptoms. The child was given a series of treatment programs， such as Azithromycin for injection for anti-infection， Methylprednisolone sodium succinate for injection for anti-inflammation， Nadroparin calcium injection for anticoagulation， Mannitol injection for reducing intracranial pressure， Dextran 40 glucose injection anti-thrombosis， Compound glycyrrhizin injection for protecting liver function， Hydrotalcite tablets for protecting gastric mucosa， intravenous immunoglobulin symptomatic supportive treatment. During the treatment， due to the poor therapeutic effect of Azithromycin for injection， it was considered that the patient may have cerebral infarction caused by refractory MP infection， so the patient’s prognosis was good when Azithromycin injection was replaced with Levofloxacin hydrochloride injection for anti-infection. For the increase of liver enzyme during the treatment， clinical pharmacist suggested that anti-infection combined with liver protection was provided   for the child and then the liver enzyme returned to normal. During the treatment， clinical pharmacist mainly monitored the interaction and possible adverse reactions among anticoagulants， glucocorticoids， liver protecting drugs， drugs for reducing cranial pressure， antipyretic and analgesic drugs， and at the same time， made medication publicity and education for the family members of the child， and inform them of the adverse reactions of drugs to be paid attention to and the precautions for taking stomach protecting drugs， glucocorticoids and other drugs. CONCLUSIONS： Cerebral infarction caused by refractory MP pneumonia in children is because of excessive immune response directly or indirectly mediated by MP. The principle of treatment is to inhibit the inflammatory response， to solve the primary disease， and symptomatic supportive treatment. Multi-drug combination is needed in the course of treatment， so it is more necessary for the clinical pharmacist to participate in the whole process and to manage the drug refinement and ensure the safety of drug use.
