Histamine releasing activity of chandonium iodide and d-tubocurarine was studied in guinea pig ileum (in vitro), guinea pig peritoneum (in vivo) and in human volunteers (in vivo) by intradermal testing at dilutions of 1:1,000 and 1:10,000 of the clinical dosage of drugs. d-tubocurarine revealed significant histamine releasing activity in in vivo animal experiments and high incidence of positive intradermal reaction, 53.5 per cent and 13.5 per cent, in human volunteers. Chandonium iodide neither showed histamine releasing activity in animals nor in man. In clinical terms, chandonium iodide appears to be a safe neuromuscular blocking agent.

DOSE RESPONSE RELATIONSHIP OF NEUROMUSCULAR BLOCKADE, INTUBATION CONDITIONS AND CARDIOVASCULAR CHANGES WITH CHANDONIUM IODIDE

One hundred and forty ASA physical status I and II patients undergoing general or gynaecological surgery were the subjects of this study. Patients were randomly assigned into five groups receiving 100, 150, 180, 200 and 250 µg/kg I.V. of chandonium iodide after induction of general anaesthesia with thiopentone. Neuromuscular blockade was assessed clinically, as well as, with twitch response/train of four using myotest nerve stimulator. Increasing dosage of chandonium iodide decreased the time to onset of jaw relaxation and apnoea (p<0.01) and caused linear increase in the duration of neuromuscular blockade from 10.90 ± 5.31 to 25.18 ± 7.15 min (p<0.01) over the dosage rage of 100 to 250 µg/kg. Intubation conditions also improved with increasing doses of chandonium iodide, so that, although intubation was possible in all the patients, grading of good intubation conditions were achieved in 64, 80, 88, 100 and 100% of patients in groups I to V respectively. 200 µg/kg of chandonium iodide produced ideal intubation conditions. Recovery to spontaneous ventilation was rapid and smooth, further facilitated with neuromuscular antagonists. Short lasting increase in heart rate and blood pressure was seen which was neither dose dependent nor outlasting the duration of neuromuscular blockade.

The effect of chandonium iodide (as a non-depolarising muscle relaxant) was studied in 50 patients of ASA grade I or II who were scheduled for surgery. The patients were divided into 2 groups according to the dose of chandonium iodide (0.2 and 0.25 mg/kg respectively). The onset and duration of action was found to be dose dependent. Intubation characteristics were good to fair in all the patients, the reaction to intubation being either absent or mild. There was mild and transient rise in pulse and blood pressure. No allergic reaction was observed in any patient and reversal characteristics were good in all the cases.
