Clinical research of the effects of carbon dioxide pneumoperitoneum on cardiovascular function in geriatric cholelithiasis / 中国现代普通外科进展

ABSTRACT

Objective: To explore the effect of CO 2 pneumoperitoneum in laparoscopic surgery on the cardiovascular function of the geriatric cholelithiasis.Methods:Sixty aged patients undergone laparoscopic surgery were selected.During various stage of CO 2 insufflation,the heart rate(HR),blood pressure,oxygen saturation ,electrocardiogram(ECG),and myocardial enzymes were dected,and the clinical values of these changes were analyzed.Results: when CO 2 pneumoperitoneum established ,the HR and blood pressure were increased obviously .The incidence of arrhythmia was 36% and the incidence of changes of ST segment was 30%,10 minutes after pneumoperitoneum eliminated,these changes were restored. The myocardial enzymes and the oxygon saturation of blood had no distinct changes. Conclusion: The procedure of CO 2 pneumoperitoneum caused temporany changes of the HR ,SBP/DSP and ECG.The laparoscopic surgery is effective and safe for geriatric cholelithiasis.It suggests that the dynamic monitoring of electrocardiogram is necessary,especially for those with abnormal heart function.
