Abstract

Despite a great number of studied and development of new treatment of various diseases, there is a lack of effective surgical access pathways to an abdominal autonomic nerve in small predatory animals. The study is purposed to develop a morphologically reasonable, species-specific surgical access of paraaortic injection of local anesthetics into an area of localization of abdominal autonomic nerves in pet dogs. The subjects of the study were corpses of mature mesomorphic pet dogs fallen of non-communicable diseases. The complex of morphological methods used in this research is as follows: normal and subtle dissection on the academic Vorobyov’s method, classic methods of production of light-optical histological medications, morphometry. With the aim of developing injection access to abdominal autonomic nerves, an injection of colored latex solution with its further dissection was used. In our investigations skeletonangiotopical relations, macro-microanatomical and histological constitution of abdominal nerves of aortal plexus were studied. Epineural structures was in pet dogs were characterized. The results of macromicroanatomical and histological studies allowed to develop a technique of paraaortal surgical access to an abdominal aortal nervous plexus in pet dogs. The proposed technique of paraaortal surgical access for a block of an abdominal aortal nervous plexus allows for full coverage an area where the sources of abdominal organs innervation are located.

Highlights

To relieve pain during surgical operations in small predatory animals, most authors recommend to use an anesthesia and a neuroleptanalgesia
It has been established that the sources of formation of abdominal aortal plexus are located in close proximity to each other in an osteotopical projection of the 12-th – the 2-nd lumber vertebra and is incarcerated here in circumvascular loose fibrous connective tissue in the initial section of abdominal aorta
Macro-microanatomical and histological studies have shown allowed for development the technique of paraaortal surgical access to an abdominal aortal neurons plexus in pet dogs

Summary

Introduction

To relieve pain during surgical operations in small predatory animals, most authors recommend to use an anesthesia and a neuroleptanalgesia. To relieve pain in abdominal and pelvic inner organs, peridural or subarachnoidal surgical accesses for spinal anesthesia conduction and massive intravascular injection of novocaine and lidocaine are suggested [1,2,3,4,5,6]. The way forward in this field of veterinary were investigations by L.G.Smirnov [9] and V.V.Reshetnyak [10]. Their experimental and clinical studies allowed for development of an intraperitoneal way of Novocain injection in dogs for intraperitoneal procaine block conduction after experimental laparotomy and intestinal loop eventration
