Comparison of Glycopyrrolate, atropine and hyoscine in mixture with neostigmine for reversal of neuromuscular block following closed mitral valvotomy.
Atropine, glycopyrrolate and hyoscine were compared in a mixture with neostigmine for the reversal of neuromuscular block in patients undergoing closed mitral valvotomy. Both atropine and glycopyrrolate were effective in counteracting the muscarinic effects of neostigmine. Glycopyrrolate was, associated with less initial increase in heart rate, a factor of importance in patients with mitral stenosis. The incidence of significant dysrhythmias was low in this small series. The control of secretions was better with glycopyrrolate. Administration of hyoscine was associated with unacceptable falls in heart rate and is not recommended.
