Heart rate changes during halothane-tubocurarine anaesthesia (Group I, 60 patients), and pethidine-tubocurarine (Group II, 20 patients) have been studied. Significant changes were noted immediately after thiopentone induction, after intubation and after atropine 1.2 mg, 1.8 mg, or 3.0 mg. It was found that atropine 1.8 mg was as effective as atropine 3.0 mg in increasing heart rate, Atropine ca...

ABINOVITCH (I) in 1927 studied the effect of atropine on the absorption R of water and chloride from Thiry-Vella fistulas in two unanesthetized dogs. The atropine was administered either by subcutaneous injection or by placing it in the 0.9 per cent NaCl test solution. Rabinovitch stated that atropine increased both water and chloride absorption; however not all the data were presented, and no ...

The antimuscarinic effects of atropine were studied in 46 patients to whom neostigmine had been given after operation to reverse the action of a muscle relaxant. Neostigmine was given to alternate patients three minutes after, or together with, atropine, and the effects of the two procedures were compared by measuring the secretions which collected in the buccal and oropharyngeal cavities and o...

The elasticity of the thoracic aorta was studied in nine dogs instrumented with a pressure microtransducer and two ultrasonic crystals diametrically fixed in the adventitia. Systolic and diastolic changes in pressure and diameter were used to calculate Peterson and incremental elastic moduli. Acute hypertension was induced by infusions of angiotensin performed 1) during the control period, 2) a...
