ABSTRACT
Objective To investigate the roles of cystatin C (CysC) and serum creatinine (Scr) in acute renal injury of patients with shock. Method A total of 71 patients with shock, 42 male and 29 female, were enrolled from February 2006 to June 2007. Patients with kidney disease or renal insufficiency were excluded. All of patients were assigned to 4 groups as per the duration of shock. The blood samples were taken from patients for measurements of CysC and Scr during the periods of 1 hr,2 hr,and 4 hr of shock and 72 hr and 7 days after correction of shock. The corrected GFR (cGFR) and decreased GFR (dGFR) were calculated. The levels of Scr and dGFR could be used to classify the acute renal injury into stages according to the Acute Kidney Injury Diagnosis Criteria. The positive detection rates of different methods were compared. The levels of CysC, Scr and cGFR were statistically analyzed. Data were studied by using Pearson's correlation analysis, Results The elevation of CysC appeared sooner than that of Scr in all shock patients. Contrarily, the high level of CysC lowered to normal level much slower than that of SCR after correction of shock. The CysC increased 1 hour after shock. The GFR was negatively correlated with CysC and Scr, especially in the early stage of shock. Conclusions The renal dysfunction appears in the early stage of shock. The CysC assayed is more sensitive in the stage 1 of renal injury than Scr.
ABSTRACT
Objective To investigate Iomoxicam,paracetamol,trarnadol in post-operative analgesia of surgical abortion.Methods 200 patients undergoing surgical abortion were randomly allocated into four groups:lornoxicam,paracetamol,tramadol and the control group.Intravenous anesthesia was conducted.Lomoxicam 16 mg,paracetamol 1000mg,tramadol 100 mg were administered before patients awaking.VAS scores and complications were observed post-operation.Pre-operative and post-operative salivary cortisol was detected.Results VAS scores were less in the 3 analgesic groups than in control group at 15,30 minutes post-operation(P＜0.05).VAS scores had no difference in all groups at 60,120 minutes.Cortisol was higher in the control on the next day(P＜0.05).Conclusion Post-operative analgesia was effective for surgical abortion.
ABSTRACT
Objective To investigate effect of lipid emulsion on cardiac arrest induced by bupivacain intoxication.Methods Forty SD rats were randomly devided into 2 groups.Group A applied epinephrine (n=20);Group L applied lipid emulsion combinding epinephring(n=20).The rats were administered Lupivacaine 20 mg/kg.Cardiopulmonary resuscitation(CPR) was started. Epinephrine 10 μg/kg were repeated three times followed by epinephrine 10 μg/kg every 5 minutes.Normal saline 5 ml/kg and 1 ml·kg-1·min-1 were administered in group A.20% Lipid emulsion 5 ml/kg and 0.25 ml·kg-1·min-1 were administered in group L.Heart rate,blood pressure, temperature were monitored.Blood gas analysiswere checked at 5 min,30 min after restoration of spontaneous circulation(ROSC).To record the number of successful CPR,time of ROSC and epinephrine dose.Results 11 rats(55%) and 16 rats(80%) were successful resuscitated.The success rate was higher in group L than in group A.Epinephrine dose was higher in group A than in group L.There was no difference in heart rate between the two groups.Systolic blood pressure and PaO2 was higher in group L than in group A(P<0.05).Conclusion There was better effect in lipid emulsion combined epinephrine than soly epinephrine when applied in cardiac arrest induced by bupivacaine intoxication.
ABSTRACT
Objective To investigate ultrasound guidended nerve block of femoral nerve in emergency operation.Methods 40 patients who planned to accept surgery of feet,lower limb under knee.They were randomly devided into 2 groups:ultrasound guidended group and the control group.Femoral nerve and Sciatic nerve were blocked by ultrasound guidended technique or classic landmark technique.1.5% lidocaine was administered for nerve block.Sensory block was observed every 5 minutes in 30 minutes.Onset time,effect of anesthesia,algesia time and complications were recorded.T-test and varience difference were applied.Results The onset time of local anesthetics was faster in the ultrasound guided group than that of the control group.Effect of analgesia was better in in the ultrasound guided group than that of the control group. Conclusion Nerve block of femoral nerve and the sciatic nerve guided by ultrasound was better than the classic technique.
