The early detection of the effects of surgical shock on the viscera

One hundred and one patients, in shock after operations were reviewed to examine the visceral effects on their prognoses. The shock was caused in 65 cases by hypovolaemia and in 36 cases by sepsis. The effects were studied on the heart and cardiovascular system, liver, kidneys, gastrointestinal system, central nervous system, lungs and blood clotting system. Surgical shock affected more frequently the lung and liver ( P < 0.05 and P < 0.01). The lungs were most frequently involved in hypovolaemia (25 patients) and sepsis (25 cases). Pathology of the lung was associated with the highest mortality rate ( P < 0.005), followed by kidney ( P < 0.01) then heart and central nervous system ( P < 0.025). Involvement of the gastrointestinal tract or clotting system alone was not associated with higher mortality rates, except in the presence of other visceral derangements. Lung affection also had a greater mortality followed by kidney and the central nervous system. Involvement of one or several organs in failure to survive septic shock is dealt with in the discussion. It is concluded that visceral involvement secondary to shock could be of importance for prognosis.
