Experience of successful treatment of ultra-long cardiopulmonary and brain resuscitation under mild hypothermia
Objective This case report describes the treatment of a patient with J-wave syndrome who experienced two cardiac arrests and discusses the potential role of mild hypothermia in cardiopulmonary and cerebral resuscitation.Methods A patient with J-wave syndrome was admitted to the department of emergency of Qingpu Branch of Zhongshan Hospital Affiliated with Fudan University.During the treatment,mild hypothermia was adopted for brain protection.The patient suffered cardiac arrest again in the hospital.After continuous cardiopulmonary resuscitation(CPR)for 230 minutes under mild hypothermia,sinus rhythm was restored.By sharing the diagnostic approach and treatment process,valuable insights can be gained to improve patient outcomes in similar cases.Results A 17-year-old female patient was admitted to department of emergency of Qingpu Branch of Zhongshan Hospital Affiliated with Fudan University on September 30,2021 due to sudden loss of consciousness for 30 minutes after running.She fainted 3 times in the past after excise and nervousness.CPR was performed immediately after the syncope,and an ambulance arrived at the scene 10 minutes later,and electrical defibrillation and tracheal intubation mechanical ventilation were conducted.When admitted to the intensive care unit(ICU),the patient continued to have tetanic convulsions.To manage these symptoms,the medical team administered sedation and anti-epileptic treatment while focusing on maintaining internal environment stability.Additionally,mild hypothermia treatment was initiated,controlling the patient's core body temperature at 34-36℃.With these interventions,the tetanic convulsions gradually subsided during the night.At 11:40 on October 1,the electrocardiogram(ECG)monitoring indicated ventricular fibrillation,and immediate rescue efforts such as CPR,electrical defibrillation,and blood pressure elevation were given.Due to recurrent ventricular fibrillation,the patient underwent repeated shock defibrillation and chest compressions with the CPR machine.Antiarrhythmic lidocaine was administered,and epinephrine and isoproterenol were administered to maintain the heart rate above 90 bpm.At around 15:30,the heart rate stabilized and blood pressure gradually improved.After successful resuscitation,mild hypothermia and other brain protection treatment were continued.On October 4,the mind was cleared,the muscle strength was restored to normal and the tracheal intubation was removed on October 6.Holter electrocardiogram examination indicated V1-V3 ST-segment elevation,combined with the patient's history of repeated syncope,previous electrocardiogram indicated early repolarization,considering the possibility of J-wave syndrome and Brugada syndrome,the patient was discharged after implantable cardioverter defibrillator(ICD)installation.Conclusions In this case,the patient was successfully resuscitated after two cardiac arrests.Among them,CPR after cardiac arrest in hospital was successfully performed for a long time under mild hypothermia without any neurological sequelae.The treatment experience provided a reference for clinical cardiopulmonary and brain resuscitation.
