Effects of Early and Late Clamping of Umbilical Cord on Infant's Haemoglobin Level

SUXAMETHONIUM AND CARDIAC RHYTHM BiuTisH 1777 premedication failed to prevent a slowing of the heart rate on the subsequent injection of suxamethonium. Similarly, the intravenous injection of 0.6 mg. of atropine also failed to afford protection. In this investigation, however, the intravenous administration of I mg. of atropine sulphate prevented the subsequent development of bradycardia or arrhythmia in every case, even when large doses of suxamethonium were used.
