Summary The aim of this study is to find out the effects of different doses of midazolam, when used epidurally, on somatosensory
evoked potentials (SEP) by delaying neuronal conduction. Thirty two New Zeland albino male rabbits were divided into four
groups. All rabbits were anesthetised with ketamine and xylasine combination and atracurium was used as muscle relaxant. 10
mg/kg/hr ketamine infusion was used for maintenance of anesthesia. After insertion of the epidural catheter surgically; Group
1 received 1.5 ml isotonic saline (Control), Group 2 received 150 μg/kg, Group 3 received 250 μg/kg, and Group 4 received
500 μg/kg midazolam epidurally. With the stimulation of sciatic nerve, SEP records were recorded from the epidural space.
Records were received before the injection of the drug, and 20, 40, 60 minutes after injection of the drug.
“Latancy” results were increased according to control in all groups (including isotonic saline-control-group). Increase in
latancy in the control group was interpreted as due to the effect of temperature mismatch of the saline and the rabbits. While
in the first and second group amplitudes showed no differences, group 3 and 4 showed decreases of up to 50%. Epidurally administered
midazolam up to 150 μg/kg caused no change in SEP records, but 250 and 500 μg/kg doses caused decreases in SEP records which
can lead to misinterpretation as neurological damage. 相似文献

Rocuronium is a non-depolarizing neuromuscular blocking agent which is associated with injection pain and induces withdrawal movement of the injected hand or arm or generalized movements of the body after intravenous injection. The aim of this randomized study was to compare the efficacy of pretreatment with oral dexketoprofen trometamol (Arvelles®; Group A) with placebo (Group P) without tourniquet to prevent the withdrawal response caused by rocuronium injection. The study cohort comprised 150 American Society of Anaesthesiologists class I–III patients aged 18–75 years who were scheduled to undergo elective surgery with general anesthesia. The patients response to rocuronium was graded using a 4-point scale [0 = no response; 1 = movement/withdrawal at the wrist only, 2 = movement/withdrawal involving the arm only (elbow/shoulder); 3 = generalized response]. The overall incidence of withdrawal movement after rocuronium injection was significantly lower in Group A (30.1 %) than in Group P (64.6 %) (p < 0.001). The incidence of score 0 withdrawal movements was higher in Group A (69.9 %) than in Group P (35.4 %), that of score 1 withdrawal movements was similar between groups (Group A 21.9 %; Group B 26.1 %) (p = 0.560) and that of score 2 withdrawal movements was lower in Group A (8.2 %) than in Group P (38.5 %) (p < 0.001). There were no score 3 withdrawal movements in either group (p > 0.05). These results demonstrate that the preemptive administration of dexketoprofen trometamol can attenuate the degree of withdrawal movements caused by the pain of the rocuronium injection. 相似文献

A series of new compounds containing formyl and imine group were synthesized. New formyl-substituted compounds were prepared by the reaction of 1,2-bis(bromomethyl)benzene with benzaldehyde derivatives in the presence of NaOH. New bis-crown ether imine compounds were prepared by the condensation of corresponding aldehydes with 4′-aminobenzo-15-crown-5. Sodium complexes of the bis-crown ethers form crystalline 2:1 (Na+:ligand) stoichiometries were also been synthesized. The prepared compounds were structurally confirmed by analytical and spectral data and evaluated for their antibacterial and antifungal activities. The results show that the antibacterial activity of compounds including o-methoxy group was significantly higher against S. epidermis compared to the other studied antimicrobial group. 相似文献

Kounis syndrome is a life-threatening medical condition that causes severe allergic reaction and acute coronary syndrome. Benzathine penicillin G is one of the most widely used antibiotics in clinical practice, but it can enhance both allergic and hypersensitivity complications. In this report, we describe the case of a 42-year-old man admitted to our hospital who presented with cryptic tonsillitis accompanied by angioneurotic edema, chest pain, and electrocardiographic variations. The patient was diagnosed with Kounis syndrome and treated with oral antihistamines and prednisolone. He was discharged following a complete recovery and regression of electrocardiographic abnormalities within 72 hours. 相似文献
