In children, ultrasonography aids verification of the correct placement of epidural catheters (Willschke et al. 2006).

Eight piglets were enrolled in the study and grouped (n=2) according to age: 7 (P7); 14 (P14), 21 (P21) and 28 (P28) days old. The piglets were anaesthetized with sevoflurane. A US examination with a 10 Mhz linear probe was performed with piglets in lateral recumbency. The spinal catheter was placed as previously described (Lambertini et al. 2015) with the US probe between the intervertebral spaces. A spinal needle was introduced between the spinous processes of L2 and L3 lumbar vertebrae. The needle was advanced until cerebro-spinal fluid filled the hub and then replaced with a Tuohy needle, used to introduce the catheter up to the cisterna magna. The catheter advancement was monitored with the probe. At the end of procedure the catheter was removed. The piglets recovered from anaesthesia and were monitored for a week. In P7 and P14 paramedian longitudinal views generated good images of the dura mater, epidural space, subarachnoidal space and spinal cord at both cervical and lumbar levels. In P7 and P14 the US enabled real time visualization of catheter placement in cisterna magna. In P21 and P28 it was not possible to visualize neuroaxial structures.

Abstract

In children, ultrasonography aids verification of the correct placement of epidural catheters (Willschke et al. 2006). We assessed the use of ultrasound (US) during spinal catheter placement in piglets. Eight piglets were enrolled in the study and grouped (n=2) according to age: 7 (P7); 14 (P14), 21 (P21) and 28 (P28) days old. The piglets were anaesthetized with sevoflurane. A US examination with a 10 Mhz linear probe was performed with piglets in lateral recumbency. The spinal catheter was placed as previously described (Lambertini et al. 2015) with the US probe between the intervertebral spaces. A spinal needle was introduced between the spinous processes of L2 and L3 lumbar vertebrae. The needle was advanced until cerebro-spinal fluid filled the hub and then replaced with a Tuohy needle, used to introduce the catheter up to the cisterna magna. The catheter advancement was monitored with the probe. At the end of procedure the catheter was removed. The piglets recovered from anaesthesia and were monitored for a week. In P7 and P14 paramedian longitudinal views generated good images of the dura mater, epidural space, subarachnoidal space and spinal cord at both cervical and lumbar levels. In P7 and P14 the US enabled real time visualization of catheter placement in cisterna magna. In P21 and P28 it was not possible to visualize neuroaxial structures. All piglets recovered without any complication. Ultrasound examination appears useful for spinal catheter placement in piglets younger than 14 days but it is of no benefit in older animals.
