In the early post-AMI period, the QOL of patients admitted at sites with angiography was higher than that of patients admitted at sites without angiography. However, by 1 year, the QOL and functional status of patients was similar in both groups. Differences in QOL were greatest when differences in treatment were greatest, lending support to a positive albeit small association between an early invasive approach to post-AMI care and improved QOL.
BACKGROUND: Administration of analgesics per patient request or random pain assessments may provide inadequate pain management. OBJECTIVE: To examine the impact of nurses' use of a standardized pain flowsheet to document pain assessment and pharmacologic management on patient-reported pain intensity. METHODS: A pre-post intervention design was used to compare 61 patients. In the preimplementation group, traditional charting of pain presence or absence was documented in the narrative notes and pharmacologic management was recorded on the medication profile. In the postimplementation group, the intensity of pain and pharmacologic management were documented on a pain flowsheet. Within 24 hours after transfer to the step-down unit, patients were interviewed regarding pain intensity experienced in the surgical heart unit and at the time of questioning. The distribution of these pain intensity scores was compared. RESULTS: The postimplementation group reported significantly lower pain intensity ratings for the average amount of pain experienced while in the surgical heart unit, the least amount of pain experienced while in the surgical heart unit, and the pain experienced at the moment of questioning. CONCLUSIONS: Use of a standardized pain flowsheet to assess pain intensity and document pharmacologic intervention may improve pain management in postsurgical cardiovascular patients.
Trimethoprim-sulfamethoxazole (TMP-SMZ) and pentamidine are both licensed for the treatment of Pneumocystis carinii pneumonia (PCP). However, their use is associated with various adverse side effects. In this prospective study, 26 AIDS patients with 32 episodes of PCP were treated with pentamidine (4 mg/kg/d). Each patient was treated for 12 to 21 days, depending on the rapidity of onset of the clinical response. During the 32 PCP episodes, hypoglycemia occurred in 16 instances, azotemia in 12, liver toxicity in 10, and leukopenia in 8. The occurrence of thrombopenia, leukopenia, and liver toxicity was not related to age, pentamidine levels, or other complications. However, patients who had hypoglycemia during pentamidine treatment had higher serum pentamidine levels than patients who did not have hypoglycemia (107 +/- 40 versus 70 +/- 26 ng/ml, p less than 0.004). In addition, we observed that patients with azotemia showed higher pentamidine levels during treatment (120 +/- 35 versus 64 +/- 22 ng/ml, p less than 0.001). In fact, 100% (11/11) of patients with serum pentamidine concentration greater than 100 ng/ml had fasting hypoglycemia and/or azotemia, while 33% (7/21) of those with pentamidine levels less than 100 ng/ml had these side effects (p less than 0.001). The relative risk of these complications with pentamidine levels greater than 100 ng/ml was 3 (95% confidence interval, 1.6 to 5.5). Fine-tuning the dose of pentamidine may eventually prove useful to avoid toxicity and optimize therapy.
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.
