BACKGROUND In spite of more than 20 yr of research, the mechanism whereby local anaesthetics act on the brain to mediate anaesthesia still remains unclear. Furthermore, the effect of local anaesthetics on neuronal excitability and synaptic transmission in the hippocampus has not been reported. Thus, the purpose of the present study was to find out the differences between the local anaesthetics,...

Both local anaesthetics and calcium antagonists depress cardiac function. Therefore, we have studied the interaction of these compounds in the isolated myocardium of guineapigs. The negative inotropic effect of various local anaesthetics was investigated in left atria in the absence or presence of nitrendipine 10(-7) mol litre-1 (n = 7-8 in each group). In addition, the effect of bupivacaine wa...

AIM To compare the effectiveness of EMLA cream and Ametop gel in providing analgesia for venous cannulation. METHODS Single blind study in 120 children. RESULTS Both anaesthetic agents produced adequate analgesia. However, Ametop gel was more effective, with a statistically significant difference in the pain scores of the two groups (p < 0.05).

and Md., Eight synthetic local anaesthetics from among (he Propiophenones, Benzil and Phenoxy derivatives and derivatives of Benzyl alcohol wen' examined for their arrhvthmia combating activity. Against acetylcholine induced auricular fibrillation U·0045 showed maximum activity and U -0172, U·OI77, U-OS75 and Lignocaine were more active than quinidine. In aconitine induced fibrillation li.OI77,...

Methemoglobinemia is a disorder characterized by the presence of a higher than normal level of methemoglobin. Prilocaine which is one of the oxidizing local anaesthetics is widely used in many local procedures. The first choice of treatment of complications due to the use of these local anaesthetics is methylene blue, while ascorbic acid is the alternative choice. The side effects of metilen bl...

BACKGROUND Distant metastasis or local recurrence after primary tumour resection remain a major clinical problem. The anaesthetic technique used during oncologic surgery is suggested to influence the metastatic process. While awaiting the results of ongoing randomised controlled trials (RCTs), we have analyzed the evidence regarding the influence of anaesthetic drugs on experimental tumour meta...
