Abstract Objective: To analyze the effects of microchannel and standard channel percutaneous nephrolithotomy on hemodynamics and blood gas analysis in patients with renal calculus. Methods: 80 cases of renal calculus in our hospital from January 2016 to June 2018 were treated by percutaneous nephrolithotomy. They were divided into group A with microchannel and group B with standard channel, with 40 cases in each group. The perfusion volume, operation time, hemodynamics and arterial blood gas analysis indexes were compared between the two groups. Results: The perfusion volume in group B was significantly lower than that in group A, and the operative time was significantly shorter than that in group A (P<0.01). There was no significant difference in heart rate (HR) between the two groups at different time points (P> 0.05); central venous pressure (CVP) and mean arterial pressure (MAP) before perfusion (T2) were significantly lower than those before anesthesia (T1) (P< 0.05), and there was no significant difference in CVP and MAP between perfusion 10 minutes (T3) and pre-perfusion (T2) (P> 0.05); 30 minafter perfusion (T4), 60 minafter perfusion (T5) and postoperative (T6) CVP and MAP were significantly higher than those of T2 (P< 0.05); HR, CVP and MAP were not significantly different between the two groups at different time points (P> 0.05). The base excess (BE), pH and K⁺ of the two groupsafter operation (t3) were significantly lower than those before anesthesia (t1) (P<0.05); there was no significant difference in pH, K⁺, BE between the two groups at different time points (P> 0.05). There was no significant difference in the incidence of complications between the two groups (P>0.05). Conclusion: With the increase of operation time, the absorption of perfusate in patients with renal calculus treated by percutaneous nephrolithotomy has obvious influence on arterial blood gas analysis and hemodynamics, and because of the compensation of organ function, the difference of perfusion fluid absorption between standard channel and microchannel percutaneous nephrolithotomy does not cause significant difference in arterial blood gas analysis and hemodynamics.
