Effects of 3 analgesic regimens on the perception of pain after removal of femoral artery sheaths.

BACKGROUND: Effective pain management after removal of femoral artery sheaths after percutaneous transluminal coronary angioplasty is highly individualized and requires frequent, accurate assessment and administration of analgesics as needed. OBJECTIVE: To determine which of 3 analgesic regimens is most effective in decreasing patients' perception of pain with the fewest side effects after removal of a femoral artery sheath. SAMPLE: 130 adult who had undergone percutaneous transluminal coronary angioplasty and were in an 8-bed cardiac short-stay unit in a 1400-bed acute care hospital. METHOD: Patients were randomized to receive either intravenous morphine, intravenous fentanyl, subcutaneous lidocaine around the sheath site, or an intravenous placebo before sheath removal. Rescue analgesia (intravenous fentanyl) was made available to all groups. Patients used a visual analog scale to assess pain within 10 minutes before, 1 minute after, and 20 minutes after sheath removal. Pain levels, frequency of side effects, and use of rescue analgesia were compared among groups. RESULTS: Age, sex, number of stents, and frequency of hematomas did not differ significantly among groups. Pain ratings, use of rescue analgesia, and side effects (nausea, vomiting, or vasovagal symptoms) were not significantly different among treatment groups. Ratings of pain were slightly higher immediately after sheath removal in all groups. CONCLUSION: For most patients, removal of femoral artery sheaths and manual compression for hemostasis are relatively pain-free. Pain scores among patients given analgesia with subcutaneous lidocaine, intravenous morphine, or intravenous fentanyl were not significantly different from pain scores among control patients.

Femoral arterial sheath removal after PTCA: a cross-Canada survey.

A cross-sectional survey was conducted to examine current Canadian practices in the nursing and medical management of femoral arterial sheath removal (SR) after PTCA (percutaneous transluminal coronary angioplasty). The purposes of the study were to (a) investigate the roles of the nurses and physicians in SR, (b) assess the length of time arterial sheaths are left in place and patients kept on bedrest, and (c) describe the routine medical protocols used for pain and anticoagulation therapy. Of the 35 hospitals that perform PTCA in Canada, 30 responded to the survey (response rate of 86%). Nurses had primary responsibility for SR in 13% of the sites and shared responsibility with physicians for SR in a further 10% of the institutions. When nurses were trained to remove sheaths, they assumed responsibility for the adjunctive steps to establish hemostasis. One third of hospitals removed sheaths in 4 hours or less; approximately 75% of them removed sheaths in 6 hours or less after PTCA. Patients are kept on bedrest for 6 hours or less following hemostasis in half, and 8 hours or less at three-quarters of the hospitals. Post-PTCA and pre-SR anticoagulant monitoring was used in almost half of the sites. Premedication for SR varied from no premedication to combinations of three intravenous medications plus local anaesthetic. Survey results showed that in almost one quarter of the Canadian institutions where PTCA is performed, nurses play a role in SR. Results also showed that there is no uniformity in post-PTCA SR across Canada and that further research is needed to identify the optimum approach to managing this common cardiovascular procedure.

PTCA in elderly patients: hospital events.

BACKGROUND: Medical treatment of the elderly is changing to include the aggressive management of coronary artery disease with percutaneous transluminal coronary angioplasty. OBJECTIVE: The purpose of this study was to review major hospital events of patients aged 70 years or more, who underwent a first percutaneous transluminal coronary angioplasty. METHODS: A retrospective medical record review was done of 246 consecutive patients of 70 years or more, from January 1985 to December 1988, at a tertiary care community hospital. Adverse events and the factors that influenced outcome were identified. RESULTS: Of 246 patients (age range, 70-85 years, mean = 73.6), 19 died, 4 had a cerebral vascular accident, 11 had a transfusion and 11 underwent coronary artery bypass grafting. Sixteen patients had acute vessel closure and 8 died. Twenty-five patients had one event and 21 patients had more than one. DISCUSSION: The event rate after percutaneous transluminal coronary angioplasty in the elderly is high. CONCLUSIONS: Knowledge of the factors that influence adverse events (diagnostic category, success of procedure, degree of coronary artery disease and age) will assist the critical care team to plan and implement appropriate care.
