A Comparison of the Safety and Effectiveness of Two Forms of Patient-controlled Pain Medication Used After Total Hip Replacement: The E-TRANS Fentanyl Transdermal System Versus the Morphine Intravenous Pump

• Status: Completed
• Trial end date: 2005-04-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to compare two pain medications delivered by two different forms of patient-controlled analgesia (PCA) management systems: the Fentanyl HCl Patient-Controlled Transdermal System (E-TRANS fentanyl) and the morphine intravenous pump. Fentanyl HCl and morphine are narcotic pain relievers. The E-TRANS fentanyl system is a small unit worn on the patient's upper outer arm or chest that uses low-intensity electrical current to deliver fentanyl through the skin and into the patient's bloodstream. The patients studied will be those who have just received a total hip replacement.

Criteria

Inclusion Criteria:

• Patients with a pre-operative American Society of Anesthesiology Physical Status I, II, or III (Class I are healthy persons less than 80 years of age, Class II are patients over age 80 years of age with mild systemic disease, and Class III are patients with severe and non-incapacitating disease)

• Admitted to the Post-Anesthesia Care Unit after general or spinal anesthesia (using bupivacaine)

• Surgical time of up to 4 hours for total hip replacement surgery with a single surgical incision

• Awake and breathing spontaneously, with a respiratory rate of 8 to 24 breaths per minute and oxygen saturation of 90% or higher (with or without supplemental oxygen)

• Expected to remain hospitalized for at least 24 hours postoperatively

Exclusion Criteria:

• Patients whose post-operative pain would normally be managed with oral or non-narcotic pain medication

• Who received intraoperative spinal anesthesia other than bupivacaine (without epinephrine), intraoperative epidural anesthesia, or who are expected to have postoperative analgesia supplied by a continuous regional technique

• Have a history of allergy, hypersensitivity, or tolerance to fentanyl or morphine, or a history of allergy or hypersensitivity to cetylpyridinium chloride or skin adhesives, or have the presence of active skin disease that would interfere with application of the E-TRANS fentanyl system

• Who received systemic or intra-articular steroids within 1 month before surgery or during surgery

• Expected to require intensive care postoperatively or who will probably need additional surgical procedures within 72 hours
