This study examined the extent to which measures of anxiety could predict pain and the length of hospitalization following surgery in 111 patients with gallstones over and above what could be predicted on the basis of biographical and medical status variables. Self-reported pain on the third day postoperative could hardly be explained by the variables measured. Preoperative anxiety did not increase the value of the prediction. Age, type of surgery, cystitis and wound infection explained a significant proportion of the variance in postoperative hospital stay. Over and above these variables. A-state on the third postoperative day and also A-state and specific anxiety measured 1 day before surgery exerted a significant increase on the values of prediction of the length of postoperative hospitalization.
A detailed retrospective analysis was undertaken of the effect of perioperative blood transfusion on long-term survival of 113 patients with Dukes' Stages A, B and C1 cancer of the colon and 383 patients with invasive cancer of the breast who were treated in our institution between 1973 and 1978 and followed for 5 to 10 years. In the patients with colon cancer, a significant adverse effect of transfusion on long-term survival was seen. In this group there was a cumulative 5-year overall survival of 48% for the transfused and 74% for the nontransfused patients (P = 0.007, log-rank test). Perioperative blood transfusion was associated with a relative risk of 3.42 for all deaths (P = 0.005) and 4.25 for death due to cancer (P = 0.03), after adjustment for other important variables such as age, sex, stage, location of tumor, surgical procedure, and preoperative hemoglobin level. In contrast, in our study group of patients with breast cancers, who all underwent a modified radical mastectomy, no effect of blood transfusion on long-term survival was seen. Multivariate analysis adjusting for size of tumor, number of positive regional lymph nodes, menopausal status, estrogen receptor status and the addition or absence of chemotherapy, did not show any increased risk in all deaths or death due to cancer associated with blood transfusion. Although no definite explanation is available, our data show that there seems to be a difference in the relationship between perioperative blood transfusion and survival for colon and breast cancer patients.
Ninety-one patients undergoing biliary tract surgery were randomly assigned to one of three treatment groups in which different sounds were administered, by means of earphones, in a double-blind design. The effects of the administration of positive suggestions, noise or operating theatre sounds on the postoperative course were studied. Results showed that exposure to positive suggestions during general anaesthesia, as compared with noise or operating theatre sounds, protected patients older than 55 yr against prolonged postoperative stay in hospital.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
