Tetrahydrocannabinol vs. prochlorperazine. The effects of two antiemetics on patients undergoing radiotherapy 总被引:1,自引:0,他引:1
The authors tested the effectiveness of orally administered delta-9-tetrahydrocannabinol (THC) as compared to prochlorperazine for the alleviation of symptoms, such as vomiting and nausea, experienced by patients receiving radiotherapy. The test subjects rated the severity of their illness, as well as the extent of their subsequent moods, their level of concentration, their amount of physical activity, and their desire for social interaction. They chose the drug they preferred and recorded its side effects. The use of THC was slightly more beneficial than the use of prochlorperazine. 相似文献

In view of the continuing controversy regarding the use of immediate-spin crossmatch procedures in preparing blood for transfusion to patients in whom unexpected clinically significant antibodies have not been found by antibody screening by the indirect antiglobulin test (IAT), a review of 8 years' experience with such a policy was conducted. In that period, 54,725 units of packed red cells or whole blood were transfused to 10,146 patients. Four clinically overt delayed hemolytic transfusion reactions and 18 clinically silent delayed serologic transfusion reactions were found. In 3 of the 22 patients, the offending antibody(ies) were detectable in the pretransfusion serum by an enzyme IAT, but none was detectable by routine saline IAT against either a three-cell screening panel or the transfused cells. Thus, the incorporation of saline indirect antiglobulin crossmatch would not have prevented the delayed reactions. It can be concluded that the use of a saline indirect antiglobulin crossmatch offers no significant advantage over the current policy of using only immediate-spin crossmatch for those patients whose pretransfusion serum gives negative results in a three-cell screen using a saline IAT. 相似文献

Greater trochanteric advancement (GTA) is an orthopedic procedure designed to correct the biomechanical consequences of overgrowth of the greater trochanter by moving the greater trochanter and its attached muscles laterally and distally. Thirty-one children with trochanteric overgrowth who had secondary pelvic instability (Trendelenburg sign) were studied and underwent a total of 33 GTA procedures. The clinical and radiologic prerequisites for successful surgery are presented. In addition, the radiographic methods of measuring the lateral position of the trochanter, the articulotrochanteric distance, and the amount of trochanteric overgrowth are discussed. Measurements made on preoperative and postoperative radiographs revealed that surgery achieved a mean displacement laterally of 12.1 mm and distally 21 mm. Clinically, there were few complications (two children with mild myositis, one with broken hardware, one with delayed union of trochanter). Pelvic instability had disappeared in the 25 of the 30 patients who could be evaluated. 相似文献

Seventy-six consecutive patients receiving chemotherapy were evaluated for the antiemetic efficacy and side-effects of the combination of chlorpromazine (CPM) and methylprednisolone (MPN). All patients had previously received the same chemotherapy with metoclopramide in conventional dosage and experienced severe emesis. A significant antiemetic response was achieved in 70% of the patients, and in 28% of them the antiemetic protection was complete. The most common side effects were drowsiness, dry mouth and headache. The combination of CPM and MPN is effective, well tolerated and is recommended for outpatients receiving chemotherapy for cancer. 相似文献
