RESUMO
Sepsis should be defined as life-threatening organ dysfunction caused by a dys-regulated host response to infection. Continuous renal replacement therapy (CRRT) is one of the methods for the clinical treatment of sepsis. For patients undergoing CRRT, rational antimicrobial therapy is very important for the control of patient's infection. However, during CRRT, there is no clear guideline for the dose adjustment of antibiotics. In this paper, we analyzed the effect of CRRT combined with antibiotics on sepsis treatment in China and abroad, and discussed its effect on antibiotic clearance, and provided reference for clinical work.
RESUMO
Objective Microdialysis technique is a technology which can continuous monitoring of a substance′s metabolism level in specific tissues or organs,it can provide a series of substances monitoring of the liver transplantation,especially monitoring of glucose,lactate,glycerol,pyruvate and some amino acids. By the range of these substances, we can anticipate complications and ischemia?reperfusion injury after liver transplantation. In this paper we reviewed the principle, characteristics of the microdialysis technique and its applications of monitoring the ischemia?reperfusion and complications after liver transplantation,then pointed out the main problems and trends of the technology to provide a reference for further research in the field.
RESUMO
BACKGROUND:The effect of dimethyl sulfoxide cryoprotectants has been got a lot of verification in the low-temperature medical applications. But there is no literature addressing microdialysis detection of dimethyl sulfoxide cryoprotectants. OBJECTIVE:To investigate the microdialysis relative recovery of different concentrations of dimethyl sulfoxide cryoprotectants used for limb reattachment. METHODS:In vitro linear probe relative recovery of different concentrations of dimethyl sulfoxide (2%, 5%, 8%) was detected by retrodialysis gain and loss method. The correction in vivo experiment was done to estimate dimethyl sulfoxide relative recovery in rabbit amputated limbs. RESULTS AND CONCLUSION:The relative recoveries of different concentrations of dimethyl sulfoxide (2%, 5%, 8%) were (49.49±3.56)%, (46.30±1.48)%, (52.66±2.54)%using retrodialysis gain method and (50.99±6.89)%, (43.86±1.35)%, (50.67±0.75)%using retrodialysis loss method. The average recoveries were (49.48±3.18)%and (48.51±4.03)%, respectively. There was no difference in the relative recovery of dimethyl sulfoxide detected using two methods. The change of dimethyl sulfoxide concentration could not influence the retrodialysis gain and loss method calibration results. The recovery was (15.45±4.8)%in vivo. These findings indicate that the microdialysis technology is suitable for dimethyl sulfoxide sampling in vivo that has no obvious influence on the relative recovery.
RESUMO
Microdialysis is an automatic biological sampling technique that is directed into the target tissue. Microdialysis is used to monitor the changes of drug and related substances associated with pathological physiology of tumor in the target tissue at the molecular level. Microdialysis is applied to evaluate the pharmaco-kinetics of drugs in the target tissue of tumor,optimize the combination therapy,explore molecular targeted therapy and study the early diagnosis and prognosis of tumor. Microdialysis provides a new idea and method for the prevention and cure research of tumor.
