Fasting Versus a Heart-Healthy Diet Before Cardiac Catheterization: A Randomized Controlled Trial.

BACKGROUND: Patients undergoing cardiac catheterization are ordered to take nothing by mouth after midnight before their procedure with no evidence to support this practice. OBJECTIVE: To identify best practice for fasting requirements before cardiac catheterization through comparative evaluation in a prospective randomized controlled study. METHODS: The study included a convenience sample of 197 patients undergoing elective cardiac catheterization in a progressive inpatient cardiac unit at a regional heart institute in the midwestern United States. The patients were randomized into 2 groups. Patients in the heart-healthy diet group could eat a specified diet with low-acid options until the scheduled procedure. Patients in the fasting group were restricted to nothing by mouth after midnight except for sips of water with medications until the scheduled procedure. Outcome measures included patient-reported satisfaction and complications. RESULTS: Compared with patients in the fasting group, those in the heart-healthy diet group had significantly more satisfaction with the preprocedural diet. Patients in the heart-healthy diet group had less thirst and hunger before and after the procedure. No patients experienced pneumonia, aspiration, intubation, or hypoglycemia after the procedure. Fatigue, glucose level, gastrointestinal issues, and loading dose of antiplatelet medication did not differ between the groups. CONCLUSIONS: Allowing patients to eat before elective cardiac catheterization posed no safety risk and benefited patient satisfaction and overall care. The results of this study may help identify best practice for allowing patients to eat before elective procedures using conscious sedation.

Improved Patient Safety and Quality Outcomes With Amiodarone Infusions.

BACKGROUND: Amiodarone is a common intravenous medication and a known irritant to the vessel wall when administered peripherally. LOCAL PROBLEM: Nurses identified an increase in phlebitis associated with peripheral amiodarone leading to multiple catheter replacements and interruptions in drug therapy. Central venous access is recommended by the manufacturer but not practical for a short-term infusion based on the risk to the patient, time, and cost. METHODS: A 4-phased approach was used to identify a more suitable peripheral intravenous catheter. INTERVENTIONS: A collaborative effort between bedside nurses and the vascular access team evolved to look at alternative products for peripheral intravenous catheters. RESULTS: The extended dwell peripheral catheter decreased phlebitis from 54% to 5%. It also decreased interruptions in drug therapy and improved patient comfort and satisfaction. CONCLUSIONS: A practice change was implemented utilizing extended dwell peripheral catheters for intravenous amiodarone and disseminated to other units.
