AB The work attempted to explain the influence of epidural analgesia and
operations on the behaviour of complement and lymphocyte systems. There
are very few theses in the world anaesthetic literature which attempt to
explain the influence of analgesia and operations on the immune system.
Moreover, the problem is treated very superficially in these theses and
research was conducted on a small number of patients. In the face of
this fact it was decided to assess the behaviour of selected factors of
the immune system during analgesia and operations. The research
encompassed approximately 80 patients who underwent analgesia and
operations. The operated patients were divided into two groups: a
40-person research group A and a 40-person control group K. In group A
resection of the prostate gland was performed in epidural analgesia,
whereas group K underwent analgesia of the brachial plexus to be
operated within the hand and the upper limb. Because of the small extent
of sympathetic interruption and of the operation the K group was the
control group in relation to the A group where the sympathetic
interruption and the operation were extensive. During the analgesia,
operation and the 7-day post-operation period the concentration of
immunoglobulins was examined (IgG, IgA, IgM), components of the
complement (C3, C4), the total haemolithic activity of the complement
(Kc) as well lymphocyte populations and sub-populations (B, T, CD4,
CD8). Modern research techniques were used to carry out these
examinations: monoclone antibody for examining lymphocytes,
nephelometric technique for examining concentration of immunoglobulins
and components of the complement and the hemolithic method for
examination of the total activity of the complement. It was found that
epidural analgesia acts deeply depressively on the concentration of
endogenous immunoglobulins and of the components of the complement
during the day of the operation. This type of analgesia also a similar
effect on the level of total haemolithic activity of the complement.
Operation trauma on the other hand causes depression of the auxiliary T
lymphocyte population (CD4) and the stimulation of the cytotoxic T cell
subpopulation (CD8) with a pathological reduction of the quotient factor
of these lymphocyte sub-populations CD4/CD8. No statistically
significant immunologic disorders were found in the area of the factors
examined in patients who underwent operations in the area of the hand
and the upper limb with application of plexus analgesia. The presented
research results--although they do not have a correspondent in the world
anaesthetic literature--seem to prove that epidural analgesia, hitherto
regarded as a safe manner of anaesthetizing patients for operations is
not devoid of negative influences on the immune system. With regard to
immunity on the other hand, plexus analgesia seems to be a safe method
anaesthetizing patients for operations in the area of the upper limb. It
seems that the extent of sympathetic interruption caused by epidural
analgesia affects selected immune factors depressively. This is a
clinical question which still requires much research, especially in the
area of effect on the immune system because post operative infection
complications still constitute an important etiopathogenetic and medical
problem.
