Cardiac dysrhythmias during oral surgery. Comparison of hyoscine and droperidol premedication 总被引:1,自引:0,他引:1
The incidence of cardiac dysrhythmias during inpatient dental anaesthesia under halothane was studied following either hyoscine or droperidol as a supplement to papaveretum for premedication. Forty-three percent of patients given hyoscine exhibited cardiac dysrhythmias compared to 23 percent of the group given droperidol (p = 0.03). The incidence of dysrhythmias bore no relationship to the age, sex or weight of the patient, nor to the end tidal carbon dioxide tension. 相似文献

Psychomotor testing of oncall anaesthetists 总被引:1,自引:0,他引:1
The critical flicker fusion frequency and choice reaction times of 16 on-call anaesthetists were measured between 1400 and 1600, at 2300 and at 0200 hours. Critical flicker fusion decreased between the afternoon and 2300; there was no further change between 2300 and 0200. No significant differences in choice reaction times were found on any of these different occasions. 相似文献

In this paper a follow-up is presented of a case report initially described by Andersen in 1971. The patient presented with a syndrome including elements of familial periodic paralysis with hypokalaemia, long QT syndrome, ventricular ectopy, myopathy with fibre-type disproportion and dysmorphic features resembling Treacher Collins' syndrome. The main symptom was hypokalaemic paralysis. The episodes were accompanied by a lowered intracellular potassium content and an increase in intracellular sodium. Treatment with terbutaline, a Na/K-ATPase-stimulating drug, resulted in attack-free periods of approximately 9 months, after which the attacks reoccurred. The patient suffered severe attacks whenever treatment with terbutaline was stopped. The patient experienced two attacks of respiratory arrest, the second being fatal. 相似文献

Function of the peripheral serotoninergic pathways in migraine: a proposal for an experimental model
P Martelletti G Stirparo C Rinaldi BM Fusco 《Cephalalgia : an international journal of headache》1994,14(1):11-15
We propose a model for assessing the function of 5HT receptors in migraine by evaluating their expression on monocytes by means of double-labeling fluorocytometry (CD14-positive cells FITC-labeled). This model demonstrates that during headache induced in, migraine without aura sufferers given isosorbide dinitrate followed by sumatriptan treatment 5HT expression on monocytes progressively increases. This increase may be due to the activation of 5HT turnover and to the increased availability of 5HT displaced by sumatriptan from 'cerebrovascular receptors during head pain. 相似文献

The entity of chronic daily headache (CDH) is well documented, but is not included in the current classification. We divided patients with CDH into groups with and without migrainous features. This division resulted in clearly distinguishable syndromes of daily migrainous headaches (DMH) and daily tension-type headaches (DTH). Family history of headaches was more common in patients with DMH. Patients in both groups had a high incidence of caffeine or drug overuse. The clinical division into DMH and DTH was supported by our finding of a higher incidence of disturbed magnesium (Mg) metabolism in patients with DMH. Of 26 patients with DMH, 8 (30.8%) had low serum ionized, but not total, Mg levels, and 16 (61.5%) had high ionized calcium/magnesium ratios. The corresponding numbers for the 22 patients with DTH were 1 (4.5%) and 8 (30.4%). These new laboratory measurements offer possible biological markers for the diagnosis of different headache syndromes. 相似文献

Surface coils improve signal-to-noise ratios by the simple expedient of reducing field of view. The uniformity of response of these coils is poor, since signal reception is weighted toward the surface of the object, which generally is of least interest. Furthermore, whole-section transmitter coils excite the subject uniformly, so that weak signals are detected from far regions. A dual-coil arrangement permits avoidance of these problems by combining the nonuniform excitation and reception characteristics of two surface coils. 相似文献
