The effects of precurarization, with or without prior atropine medication, on heart rate, systolic time intervals (preejection period (PEP) and left ventricular ejection time (LVET)) and derivatives from these were studied in 80 healthy patients before minor surgery. Atropine (0.5-0.7 mg i.v.) exerted a vagolytic action with no changes in systolic time intervals. D-tubocurarine (0.5 mg/kg b.w.) did not affect heart rate or systolic time intervals. Both gallamine (0.3 mg/kg b.w.) and pancuronium (0.015 mg/kg b.w.) increased heart rate due to the inherent vagolytic effect. Furthermore, a short-lasting decrease in PEP and an increase in LVET were demonstrated. Consequently, a fall in PEP/LVET and a rise in 1/PEP2 were induced, indicating an increase in cardiac pump performance. These changes were blocked by prior atropine medication, a result which is not easily explainable. Possible clinical implications are discussed.

Particulate contamination in spinal analgesia

Acta Anaesthesiologica Scandinavica (1988)

Søren Eriksen

A microscopic investigation was undertaken to quantify the amount of particulate contamination in the injectates of bupivacaine 0.5% in spinal analgesia. No differences were found between samples prepared with either a glass syringe or a disposable plastic syringe, nor could differences be documented between groups where atraumatic opening of vials, perforation of vial stoppers or opening of glass ampoules was performed. The use of commercially available bacterial filters was followed by a significant increase in the amount of particulate contamination, probably filter debris. The clinical use of such filters in spinal analgesia is therefore questionable.

Effects of Nitrous Oxide oa S)stolic Time Intervals

Acta Anaesthesiologica Scandinavica (1980)

Søren Eriksen Gunnar Johannsen N A Frost

The effects of inhalation of oxygen, nitrous oxide/oxygen and nitrous oxide/nitrogen/oxygen on systolic time intervals (PEP (pre-ejection period) and LVET (left ventricular ejection time) were investigated in eight healthy persons. Nitrous oxide 40%, administered with oxygen or oxygen/nitrogen, prolonged PEP significantly by 25% and 22%, respectively. Inhalation of oxygen also prolonged PEP but to a significantly minor degree. LVET, heart rate and MAP were unchanged during the experiments. Derivatives from the systolic time intervals, i.e. PEP/LVET, I/PEP2 and ejection fraction changed significantly in the nitrous oxide groups. It is concluded that nitrous oxide depresses cardiac performance, to some degree, even when administered at a rather low concentration.
