Atracurium or vecuronium for MHS patients?
CORRESPONDENCE ATRACURIUM OR VECURONIUM FOR MHS PATIENTS? Sir,—I am writing in regard to comments made by Hunter [1] in her review entitled "Adverse Effects of Neuromuscular Blocking Drugs ", on the use of vecuronium and atracurium in malignant hyperthermia-susceptible (MHS) patients. She states that "satisfactory use of both agents has been reported in patients susceptible to malignant hyperpy...
متن کاملUse of atracurium and vecuronium in patients with oesophageal varices.
The effects of atracurium (initial dose 0.5 mg kg-1; incremental doses 0.2 mg kg-1) and vecuronium (initial dose 0.1 mg kg-1; incremental doses 0.04 mg kg-1) are described in patients with portal hypertension and some degree of liver dysfunction, and the findings compared with those from normal patients. With these doses there was no evidence of gross resistance to the two neuromuscular blocker...
متن کاملInhibition of baroreflex vagal bradycardia by nasal stimulation in rats.
Nasal stimulation provokes hypertension and bradycardia. We report here that such stimulation inhibits baroreflex vagal bradycardia (BVB). In chloralose- and urethan-anesthetized, β-adrenergic receptor-blocked rats, the aortic depressor nerves were cut and electrically stimulated to induce BVB. Nasal application of smoke, warm distilled water, or cold or hot Ringer solution suppressed BVB, but ...
متن کاملSynergism between atracurium and vecuronium in children.
In 30 children under balanced anaesthesia, we have determined dose-response curves and maintenance requirement of three dose ratio combinations of atracurium and vecuronium (10:1, 4:1 or 1.6:1 on a microgram:microgram basis). Neuromuscular block was monitored by adductor pollicis EMG. An equipotent dose ratio (4:1) was most potent, with a mean (SEM) ED95 of atracurium 95 (6) micrograms kg-1 wit...
متن کاملComparison of vecuronium, atracurium and tubocurarine in normal patients and in patients with no renal function.
Vecuronium (initial dose 0.1 mg kg-1; incremental doses 0.04 mg kg-1) was given to 21 normal and 21 anephric patients. There were no gross differences between the two groups in the effect or in the duration of action of either initial or incremental doses, except in two anephric patients who were resistant to the agent. Reversal with neostigmine was satisfactory. In normal patients the initial ...
