Background　In clinical work, we often need to perform cardiopulmonary resuscitation in some patients with special pathophysiology.　Objective　By interpreting the 2015 American Heart Association cardiopulmonary resuscitation and cardiovascular emergency guidelines to update the relevant parts, improve the ability of patients with cardiopulmonary resuscitation.　Content　Cesarean section in pregnant women with cardiopulmonary resuscitation with attention to the failure of maternal recovery. Pulmonary embolism caused by cardiac arrest, suspected or confirmed cases of early thrombolysis can be carried out, and the diagnosis of cases can also be treated by surgical thrombectomy. Opioid overdose can lead to cardiac arrest, which can be treated with naloxone and cardiopulmonary resuscitation at the same time. Local anesthetics poisoning caused by cardiac arrest during cardiopulmonary resuscitation can be used simultaneously with the rescue of fat emulsion. Cardiopulmonary resuscitation in patients with sudden cardiac arrest during percutaneous coronary intervention.　Trends　The lack of relevant literature confirms that the pressure of the inferior vena cava in the lower abdomen of the maternal is reduced by hand to the left of the uterus to reduce hypotension. And there is no conclusion about the timing of cesarean section for women. The standard for the treatment of patients with cardiac arrest caused by suspected pulmonary embolism is still controversial. In some cases, intravenous fat emulsions may enhance the efficacy of epinephrine and vasopressin, which has been confirmed by animal studies, but not supported by experimental data. The above aspects are the direction of our future exploration.
