Chinese Journal of Postgraduates of Medicine 2009;32(24):13-15
Objective To assess the effects and side effects of ropivacaine combined with sulfentanyl in epidural anesthesia for caesarean section. Methods Two hundred ASA Ⅰ- Ⅱ patients scheduled for elective caesarean section were randomly divided into 2 groups (100 cases each):group S received 0.75% ropivacaine and 0.75 μg/ml sulfentanyl; and group R received 0.75 % ropivacaine. Epidural space L2-3 was punctured and the catheter was put upward 3 cm in all patients. Local anesthetic agents were administered until a complete sensory block was established extending upper T4-T6. In the operation, Bp, HR,SpO2, ECG were observed and the onset time, the upper spread and duration of sensory block were recorded.Assessed anesthetic efficacy and side-effects on newborn. Results The onset time [(4.5±1.2) min], the time needed to reach the highest sensory level [ ( 13±5) min ] were significantly shorter and the duration of sensory block [ (402±150 ) min ] was significantly longer in group S than those in group R (P < 0.05 ). There was no significant difference in the side effects such as tachycardia, nausea, vomiting, and shivering. Apgar score in newborn was not affected. Conclusion The anesthetic efficacy of epidural 0.75% ropivacaine is significantly enhanced which also has smaller local anesthetic requirements and low incidence of side-effects,in epidural anesthesia for caesarean section when sulfentanyl is added.
5.Establishing better biological models to understand occlusion.I:TM joint anatomic relationships
Journal of Practical Stomatology 2015;(4):560-576
Belief in and rejection of a relationship of occlusion and temporomandibular joint (TMJ)condyle-fossa position with normal and abnormal function are still contentious issues.Clinical opinions can be strong,but support in most published data (mostly univariate)is problematic.Distribution overlap,low sensitivity and specificity are a common basis to reject any useful prediction value.Notwithstanding,a relationship of form with function is a basic tenet of biology.These are multifactor problems,but the questions mostly have not been analysed as such.This review moves the question forward by focusing on TMjoint anatomic organisation as the multifactor system it is expected to be in a closed system like a synovial joint.Multifactor analysis allows the data to speak for itself and reduces bias.Classification tree analysis revealed useful prediction values and usable clinical models which are illustrated,backed up by stepwise logistic regression.Explained vari-ance,R2 ,predicting normals from pooled TMJ patients was 32.6%,sensitivity 67.9%,specificity 85.7%;37% versus disc displacement with reduction;and 28.8% versus disc displacement without reduction.Significant osseous organisational differences between TMjoints with clicking and locking suggest that this is not necessarily a single disease continuum.However,a subset of joints with clicking contained char-acteristics of joints with locking that might contribute to symptom progression versus resistance.Moderately strong models confirm there is a relationship between TMJ osseous organisation and function,but it should not be overstated.More than one model of normals and of TMde-rangement organisation is revealed.The implications to clinical decision-making are discussed.
6.Observation of the effect of urokinase thrombolysis combined the guide wire fragmentation and low molecular heparin anticoagulation for the treatment of arteriovenous fistula embolization
Chinese Journal of Primary Medicine and Pharmacy 2015;(17):2667-2669
Objective To analyze the curative effect used the common urokinase thrombolysis combined with topo-guide-wire fragmentation and low molecular heparin in the treatment of hemodialysis patients with arteriove-nous fistula embolization and explore the prospects of its application.Methods 30 hemodialysis patients with arterio-venous fistula embolization were divided into 15 cases of thrombolysis group and 15 cases of thrombectomy group ac-cording to the voluntary.The thrombolysis group was given simple urokinase thrombolysis,and the thrombectomy group was given thrombectomy combined with anticoagulant therapy.The curative effect and the difference in complication were compared.Results In curative effect,the recanalization rate,using time after recanalization,and dosage of uro-kinase of the thrombectomy group were better than those of the thrombolysis group[13cases vs.7cases,(22.13 ± 17.51)months vs.(11.05 ±10.55)months,(40.48 ±22.26)ten thousands IU vs.(60.29 ±15.81)ten thousands IU,χ2 =5.40,t=2.10,all P<0.05,t=2.81,P<0.01].In complication,there was no difference in the number of bleeding cases between the two groups(2cases vs.3cases,χ2 =0.24,P>0.05).For the thrombectomy group,there were fewer cases of re -embolization after recanalization (2 cases/13 cases vs.4 cases/7 cases,χ2 =3.85,P <0.05),but more cases of organ embolism(4 cases vs.0 cases,χ2 =4.62,P<0.05).Conclusion Compared with the traditional urokinase thrombolytic therapy,the guide wire fragmentation combined with low molecular weight hepa-rin anticoagulant therapy has a higher fistula recanalization rate and a lower re-embolization rate.It does not increase the incidence of bleeding complications.Besides,it can extend the use of internal fistula.However,it may cause the serious organ embolism,so it is necessary to strictly grasp the indications,applying only to the patients who are in the poor efficiency of thrombolytic and unable to have another operation.
