The frequency of cardiovascular adverse effects of cervical nerve root infiltration was investigated by means of a prospective study.


The hemodynamic and respiratory parameters systolic and diastolic blood pressure, heart rate, respiratory rate and oxygen saturation were monitored continuously in 56 patients undergoing cervical spine nerve root infiltration (injection of 10 ml Lidocain 0.5 %, mean depth of injection 5 cm). The monitored time frame ranged from 5 minutes before to 10 minutes after its administration, an additional holter-monitoring began 1 day prior to the injection.


Severe complications such as syncopes were not observed in any of the 56 patients, 4 patients developed presyncopes. None of the registered parameters showed a significant change. In a group of patients with known, pre-existing cardiovascular morbidity, no significant changes occurred either. No relevant cardiac arrhythmias were observed.


The observed cardiovascular complications were not severe. Most probably, the observed reactions were vasavagal presyncopes. Supine positioning led to immediate recovery in all of these patients. A complete hemodynamic monitoring and the placement of an intravenous line do not seem to be absolute necessities in the routine cervical nerve root infiltration.
