Conclusion
The US-ESPB which is mainly used as an antalgic rather than
anaesthesiology block, represents a valid anaesthetic alternative for
thoracic wall operations whose patients have contraindications to the GA
without clinically disrupting the respiratory mechanism and without
determining any hemodynamic impact.
In our opinion the direction of the needle is fundamental to address the
spread of the anesthetic mixture. In our clinical case the choice of the
cranial caudal approach was well considered before performing the
procedure. The position of the patient is quite important for the
execution of the block. According to our experience the sitting position
is the best in terms of simplification of the technique.
