Abstract:
Objective To investigate the effect of carbon dioxide pneumoperitoneum on the ox-ygen carrying capacity and electrolyte levels in the salvaged autologous blood undergoing laparoscopic surgery.To evaluate the clinical application value and to provide guidance for the salvage and transfu-sion of autologous blood in laparoscopic surgery.Methods Twenty cases who underwent laparoscopic surgery (group CP,laparoscopic hepatic hemangioma surgery)and twenty cases who underwent open surgery(group NCP,spinal surgery),including eighteen males and twenty-two females,aged 27-79, BMI 1.64-24.46 kg/m2,ASA Ⅰ-Ⅱ,were selected from Peking University People's Hospital from May 2016 to August 2017.Cases in both groups underwent general anesthesia.NBP,IBP,ECG, HR,SpO2,PETCO2,CVP,BIS and T were monitored and autologous blood salvage and transfusion were used during the operation.Arterial blood samples were collected from patients 10 min before and after autologous blood transfusion,salvaged blood samples were collected 1 min before and after fil-tration.Blood gas analysis,including the level of pH,PCO2,PO2,SO2,Hct,Hb,Lac and the con-centrations of Na+,K+,Ca2+,Cl-,Mg2+,were performed on all blood samples.Recording opera-tion time and blood in vitro time,blood loss volume intraoperative,total blood volume of salvage and transfusion.Results In group CP,pH,PO2and SO2of autologous blood 1 min before and after fil-tration were significantly lower than those of arterial blood 10 min before and after autologous blood transfusion (P<0.05).In group NCP,pH of autologous blood 1 min before and after filtration was significantly higher than that of arterial blood 10 min before and after autologous blood transfusion, while PCO2and PO2were significantly lower than the latter(P<0.05).PH,PO2and SO2of autolo-gous blood in group CP were significantly lower while PCO2was significantly higher than group NCP (P<0.05).PH of arterial blood 10 min after autologous blood transfusion was significantly lower while PCO2was significantly higher than group NCP (P<0.05).In group CP,the concentration of Na+and Cl- in autologous blood 1 min after filtration were significantly higher than those before fil-tration and the arterial blood 10 min before and after autologous blood transfusion.The concentration of K+,Ca2+and Mg2+in autologous blood 1 min after filtration were significantly lower than the lat-ter three blood samples (P<0.05).In group NCP,the concentrations of Na+and Cl- in autologous blood 1 min after filtration were significantly higher than those in arterial blood 10 min before and af-ter autologous blood transfusion.The concentrations of K+,Ca2+and Mg2+were significantly lower than those in the latter two blood samples (P<0.05).There were no significant differences in elec-trolyte concentration of all blood samples between two groups.Conclusion The salvaged blood in lap-aroscopic surgery is superacid and carrying less oxygen.After transfusion,may change patients'acid-base balance and increase the risk of acidosis.Its clinical application value need more further explora-tions.
