Abstract:
Objective To investigate the effect of one-lung ventilation (OLV) on the occurrence of subcutanous emphysema during retroperitoneal laparoscopic urologic surgery (RPLUS).Methods Twenty-seven ASA Ⅰor Ⅱ patients,aged 29-64 yr,with body mass index 19-25 kg/m2,scheduled for elective RPLUS,were randomly divided into 2 groups:two-lung ventilation (TLV) group (group Ⅰ,n =15) and OLV group (group Ⅱ,n =12).In group Ⅰ,the patients were tracheal intubated and TLV was performed.In group Ⅱ,the left-sided double lumen endobronchial tube was inserted and TLV was performed,OLV on the non-operated side was performed starting from 10-15 min before pneumoperitoneum and TLV resumed at the end of pneumoperitoneum.The end-tidal CO2 partial pressure and minute ventilation volume were measured before pneumoperitoneum (T1),at 30 and 60 min of pneumoperitoneum (T2,3),and at 30 min after the end of pneumoperitoneum (T4).The CO2 absorption capacity was calculated.The degree of pneumoderma was assessed and the occurance of pneumoderma was recorded at the end of pneumoperitoneum.Results Compared with group Ⅰ,the CO2 absorption capacity was significantly reduced,and the degree and incidence of pneumoderma were significantly decreased in group Ⅱ (P ＜ 0.05).Conclusion OLV on the non-operated side can reduce the CO2 absorption capacity,decrease the degree of subcutaneous emphysema and reduce the occurrence of subcutanous emphysema during pneumoperitoneum in patients undergoing RPLUS.
