“…This is a much lower figure than previous workers have reported (Browse et al, 1974(Browse et al, , 1976 but is in agreement with Knight and Metrevelli (1977). The low incidence in Knight and Metrevelli's patients might be explained by the fact that 11 of the 26 patients studied underwent hernia repair, a group of patients in whom thromboembolism rarely occurs.…”

SummaryThe incidence of postoperative thromboembolism was studied using radioisotope lung perfusion and ventilation scanning. 26% of patients had defects on their pre-operative scans and 8% developed new unmatched perfusion defects postoperatively, indicating possible pulmonary emboli. This latter figure was much lower than some previously recorded results and was similar in 2 groups of patients-one receiving dextran 70 prophylaxis during operation and the other a control group who received saline. IntroductionPost-mortem studies have revealed the true

“…This figure is almost certainly too low, however, as l25I-fibrinogen labelling and routine lung scanning were not employed [Kakkar et al, 1975;Knight and Metrewelli, 1977], We found evidence of an acute confusional state post-operatively in almost 1 in 10 of our elderly surgical patients, which is sim ilar to the incidence of 14% reported in a recent prospective study by Millar [1981]. Palmberg and Hirsjarvi [1981] estimated that 11.2% of their elderly patients developed post-operative confusional states and sugested that such patients might be at higher risk of developing dementia in later years.…”

A prospective study of post-operative morbidity in 258 elderly general surgical patients is reported. In 35% of patients no post-operative complications developed. Respiratory, wound and cardiac complications were the leading types of post-operative morbidity encountered, occurring in 39.5, 16.3, and 12.4% of patients, respectively. Life-threatening complications developed after surgery in 18.6% of patients, and the post-operative mortality rate (excluding ‘non-viable’ patients) was 5.8%. A statistical analysis of the effect of sex, age, urgency of surgery, type of surgery, and patient fitness on the pattern of post-operative morbidity revealed a number of significant associations which have not been previously identified in the elderly surgical patient.

“…These results are consistent with those of McNEIL (1976). KNIGHT & METREWELLI (1977) found no correlation between the presence of perfusion defects without defects also in ventilation and deep vein thrombosis as demonstrated by 125I-fibrinogen scanning of the legs in a postoperative series. However, this does not mean that such perfusion defects may not be due to pulmonary embolism, since 125I-fibrinogen scanning is unable to detect thrombosis in the central veins in the leg above the middle of the thigh, i.e.…”
