Abstract The failure rate and complications following thoracic and lumbar paravertebral blocks performed in 620 adults and 42 children were recorded. The technique failure rate in adults was 6.1\%. No failures occurred in children. The complications recorded were: inadvertent vascular puncture (6.8\%); hypotension (4.0\%); haematoma (2.4\%); pain at site of skin puncture (1.3\%); signs of epidural or intrathecal spread (1.0\%); pleural puncture (0.8\%); pneumothorax (0.5\%). No complications were noted in the children. The use of a bilateral paravertebral technique was found approximately to double the likelihood of inadvertent vascular puncture (9\% vs. 5\%) and to cause an eight-fold increase in pleural puncture and pneumothorax (3\% vs. 0.4\%), when compared with unilateral blocks. The incidence of other complications was similar between bilateral and unilateral blocks.
