Description
Abstract
Esta tesis reúne tres estudios cadavéricos que investigan la distribución de una mezcla de azul de metileno (AM) y iopromida (IOP) inyectada siguiendo tres técnicas diferentes de anestesia locorregional ecoguiada: el bloqueo del cuadrado lumbar (QL), el bloqueo de la vaina interna del recto del abdomen (RS) y el bloqueo del plano profundo del serrato ventral del tórax (DSP).
Objetivos:
Fueron (1) la descripción anatómica y sonoanatómica de las regiones epaxial y lateral del tórax, e hipaxial a nivel toracolumbar, (2) evaluar la viabilidad de las técnicas, (3) describir la distribución de IOP por tomografía computarizada (TC) y (4) la distribución de AM, así como la tinción de los nervios implicados en cada región mediante disección anatómica.
Metodología:
Se utilizaron cadáveres de gato eutanasiados por razones ajenas a esta tesis y donados a la Facultad de Veterinaria de la Universidad de Murcia. Los estudios fueron divididos en dos fases. En la primera, se realizó el estudio anatómico y sonoatómico de las regiones descritas. En la segunda fase, se realizó la administración ecoguiada y estudio (TC y disección) de la combinación de AM/IOP, en las tres áreas corporales.
Resultados y conclusiones:
Nuestros resultados confirmaron la viabilidad de los tres bloqueos. En QL podría aportar analgesia a la pared abdominal media y caudal, así como a todo el conjunto de las vísceras abdominales. Sin embargo, la obtención de analgesia a la zona craneal de la pared abdominal no estaría garantizado. El RS podría inducir analgesia a la pared ventral del abdomen craneal y medio, pero no al abdomen caudal. Por último, el DSP podría resultar adecuado en el aporte analgésico de la pared lateral del tórax craneal, además de ocasionalmente, extender su área de desensibilización a la zona cutánea epaxial de esta región.
This thesis integrates three different studies that describe the distribution of a mixture of methylene blue (MB) and iopromide (IOP) injected following three ultrasound-guided locoregional techniques: the quadratus lumborum block (QL), the rectus sheath block (RS) and the deep serratus plane block (DSP). Its aims were (1) to describe the anatomy and sonoanatomy of the r epaxial and lateral thorax regions and the hypaxial thoracoclumbar region., (2) to assess the feasibility of the techniques, (3) to describe the IOPdistribution assessed by Computer Tomography scan (CT) and (4) to describe the MB distribution and the number of nerves stained by anatomic dissection. To achieve this, several cat cadavers, euthanized for reasons unrelated to this thesis and donated to the Faculty of Veterinary Medicine of the Universidad Murcia, were used. The studies were divided into two phases. In phase one, the anatomic and sonoanatomic regional structures were assessed. In phase two, after performing the locoregional blocks, a CT and anatomic dissection were carried out and the distribution of the MB/IOP combination was assessed. Our results showed that all blocks are feasible in cat cadavers. The QL could provide anaesthesia to the cranial and caudal abdominal wall and the abdominal viscera. Nevertheless, the cranial abdominal wall might not be covered. The RS could provide anaesthesia to the cranial and middle abdominal wall, but it might not cover the caudal abdominal wall. The DSP could be useful in providing local anaesthesia to the thoracic lateral wall and it may also cover the epaxial region.
