ABSTRACT
Objective To study the infection prevention effect of a new type of bulb syringe during posterior lumbar surgery, which can execute pulse irrigation continuously. Methods Totally 30 patients undergoing multi-level posterior lumbar interbody fusion surgery from June to December 2016 were divided into an experiment group and a control group. The experiment group applied the bulb syringe, and the control group used tipping irrigation. The two groups were compared on intraoperative irrigation time, the development trend of C-reactive protein (CRP) 1, 3 and 5 days after surgery, incidence of postoperative pyrexia, wound healing and suture-removal time. Results The experimental group had the intraoperative irrigation time being (2.13±0.15)min, which was significantly shorter than that [(5.59±1.24)min] in the control group. In the experimental group, the CRP measurement values 1, 3 and 5 days after surgery were 46, 19 and 5 mg/L respectively and showed adeclining trend;in the control group, the CRP measurement values 1, 3 and 5 days after surgery were 49, 52 and 61 mg/L respectively and showed an increasing trend. There were 3 cases of incision exudation in the control group while none in the experimental group. The experimental group had the suture-removal time being 11.57 d, which was statistically less than that (14.29 d) in the control group. The body temperature 3 and 5 days after surgery was (37.1±2.26) and (37.0±0.12)℃respectively in the experimental group while (38.2 ±3.34) and (37.5 ±0.25)℃in the control group, and there were obvious differences between the two groups (P<0.05). There were no infected incision occurred in the two groups. Conclusion The bulb syringe gains advantages over the traditional irrigation in easy operation, short time and incidence of infected incision, and thus is worthy promoting clinically.
ABSTRACT
Objective To investigate the impact of different irrigation time on oxygenation in-dex and acid-base balance during percutaneous nephrolithotomy(PCNL).Methods Forty patients un-dergoing selective PCNL were included in this study,were divided into two groups:group S,irrigation time<120 min(n=22);group L,irrigation time≥120 min(n=18).PaO2/FiO2 ,pH and BE were determined before and after irrigation,CVP were recorded before irrigation and every 20 min during irrigation. Results The CVP maximum value were higher in group L than that in group S during irrigation (P <0.05).The PaO2/FiO2 were lower after irrigation than that before irrigation in group L(P<0.05).The pH and BE were lower in group L than that in group S after irrigation(P<0.05).Conclusion Irrigation fluid absorption is observed during PCNL.That can provoke oxygenation function decline and metabolic ac-idosis with irrigation time extend,the operation time properly shortened.
