ONE CENTURY OF THORACIC SPINAL ANESTHESIA HISTORY • In 1909, Thomas Jonnescoproposed the use of thoracicspinal block for surgeries of the neck, and thorax. • He performed punctures between T1 and T2 vertebrae • ‘ I have a total of 1,015 thoracic spinal analgesia all without death and without any serious complication’ Jonnesco T. General spinal analgesia. Br Med J 1909;2:1396-1401
ONE CENTURY OF THORACIC SPINAL ANESTHESIA HISTORY • In 2006, Andre Van Zundertet al. proposed segmental spinal block, for lap cholecystectomy in a patient with severe obstructive lung disease, using a low thoracic puncture (T10) for CSE block. van Zundert AJ, Stultiens G, Jakimowicz J et al.

Technique • A CSE technique….at the T10 interspace using a 16 g Tuohy needle and a mid-line approach. • The epidural space is identified using the ‘loss of resistance’ to air method. van Zundert AA, Stultiens G, Jakimowicz JJ et al.

SAJAA 2008; 14(1): 63-69
Technique • The distance from skin to epidural space being calculated from the length of needle protruding from the skin. • A 27 G pencil point spinal needle is advanced through the first needle until the resistance of the dura mater is felt van Zundert AA, Stultiens G, Jakimowicz JJ et al.

Technique The dura is then pierced The two needles secured together by a locking device …..ensures that the spinal needle does not move any further forward van Zundert AA, Stultiens G, Jakimowicz JJ et al.

Technique • Once flow of clear CSF has confirmed correct placement • Inject 1 ml isobaric bupivacaine 5 mg/ml + 0.5 ml of sufentanil/fentanyl van Zundert AA, Stultiens G, Jakimowicz JJ et al.

Technique • Only when the block is considered adequate • An effectiveblock extent includes the T4 to L2 dermatomes, evaluated by pinprick

Although…….. • Accidental dural puncture during needle insertion occurrs in 0.4%–1.2% of thoracic epidural blocks • None of these patients developed subsequent neurologic sequelae Scherer R, Schmutzler M, Giebler R, et al Complications related to thoracic epidural analgesia: a prospective study in 1071 surgical patients. ActaAnaesthesiolScand 1993;37:370–74 Giebler RM, Scherer RU, Peters J. Incidence of neurologic complications related to thoracic epidural catheterization. Anesthesiology 1997;86:55–63
Cons!!!!! • Spinal cord damage is a potentially disastrous complication of spinal anaesthesia or indeed dural puncture for any reason • although rare but the risk of neurological complication subsequent to spinal anaesthesia is rather real than theoretical with permanent neurological deficit occurring in 1 in 10000
Recommendations • Patient safetytakes precedence over unnecessary risks to be taken for the success of the procedure. • It is not a method that could be easily and safely applied by the majority of anesthetists • This technique is reserved for experienced cliniciansworking in defined and approved evaluation programes, and that it must not yet be used in routine clinical practice
