    Notes: The factors responsible for the spreading pattern of a single paravertebral injection are still uncertain. In this study, 28 patients were randomly assigned to receive a paravertebral injection of radio-opaque dye (10 ml, with or without co-administration of 20 ml of local anaesthetics) either dorsal or ventral to the endothoracic fascia. The point of injection was determined by use of a nerve-stimulator and the radiographic distribution pattern was assessed blindly by a radiologist. Injections made in the more ventral part of the thoracic paravertebral space, supposedly anterior to the endothoracic fascia, resulted in a multisegmental longitudinal spreading pattern, whereas injections made dorsal to the endothoracic fascia resulted in a less predictable cloud-like spreading pattern, with only limited distribution over adjacent segments. The use of a nerve stimulator-guided technique appears to enhance the likelihood of achieving the more desirable longitudinal spreading pattern.

    Notes: 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.

    Notes: Background: Descriptive data report a very low rate of postoperative nausea and vomiting (PONV) following spinal anaesthesia in children. In an attempt to corroborate this observation, we designed a prospective randomized study to compare spinal anaesthesia with intravenous propofol sedation (SA) (n=21) to inhalational sevoflurane anaesthesia (IA) (n=19) with regard to PONV and postoperative analgesia in children (aged 3–12 years) undergoing ambulatory inguinal surgery. Results: No difference was found concerning the number of patients experiencing PONV in each group (SA 1/21 versus IA 5/19; P=0.085). However, spinal anaesthesia was associated with a reduced number of PONV episodes (1/21) compared with inhalation anaesthesia (8/19) (P=0.014) and the need for supplemental postoperative analgesia with ketoralac was significantly lower in the SA group (3/21) compared to the IA group (14/19) (P 〈 0.001). Despite these benefits of spinal anaesthesia compared with inhalational anaesthesia, spinal anaesthesia did not decrease the time to discharge from the ambulatory surgery unit [SA 161 (SD 51) min, IA 164 (SD 41) min; P=NS] and the overall PONV experience was rated as ‘no problem’ by all patients, except one, regardless of anaesthetic protocol used. Conclusions: Despite the reduced number of emetic episodes and the better immediate postoperative analgesia associated with spinal anaesthesia, no difference could be identified between the two different anaesthetic protocols regarding time to discharge or overall patient satisfaction. Thus, despite minor advantages associated with spinal anaesthesia with propofol sedation, both anaesthetic regimen appear equally suitable for use in the paediatric outpatient setting.
