[Factor analysis for the prognosis of perioperative cardiopulmonary resuscitation]

To provide guidance to implement effective perioperative cardiopulmonary resuscitation.

A total of 69 perioperative cardiac arrest patients who received Cardiopulmonary resuscitation according to the 2005 guidelines in Sir Run Run Shaw Hospital from January 2005 to June 2012 were included (including emergency operation). According to the results of cardiopulmonary resuscitation, divide these 69 patients in to two groups, Successful resuscitation group (27cases) and failed resuscitation group (42cases). Compare the age, gender, ASA physical status, BMI, type of anesthesia, time that cardiac arrest occurred, cardiac arrest type, amount of bleeding, CPR duration, hypotension duration, defibrillation time, combined cardiovascular disease between successful resuscitation group and failed resuscitation group, calculate the measurement data for the chi-square test and logistic regression, derive factors that affect the success rate of cardiopulmonary resuscitation.

A total of 69 perioperative cardiac arrest patients, according to Logistic regression, ASA IV-V (P = 0.029,OR = 1.956, CI = 1.226-4.809), amount of bleeding more than 1500 ml(P = 0.023,OR = 1.615, CI = 1.245-2.313), CPR duration more than 30 min(P = 0.003,OR = 3.54, CI = 3.313-5.007), hypotension duration more than 30 min(P = 0.002,OR = 2.782, CI = 1.791-4.322), the type of cardiac arrest is pulseless electrical activity(P = 0.032,OR = 1.419, CI = 0.146-1.583).

ASA IV-V, amount of bleeding more than 1500 ml, CPR duration more than 30 min, hypotension duration more than 30 min and pulseless electrical activity are the Independent risk factors of cardiopulmonary resuscitation.
