What is a good hydromorphone (Dilaudid) rate on Patient-Controlled Analgesia (PCA)?

From the Guidelines

A good hydromorphone (Dilaudid) rate on Patient-Controlled Analgesia (PCA) is 0.2-0.5 mg per demand dose, with a lockout interval of 5-10 minutes and a basal rate of 0.01-0.05 mg/hour, as this allows for effective pain management while minimizing the risk of adverse effects.

Key Considerations

• The recommended dose is based on the study's suggestion of a 1 mg + 1 mg patient-driven protocol for acute pain management, which can be adapted for PCA use 1.
• Hydromorphone has a quicker onset of action compared to morphine, making it a suitable choice for PCA 1.
• The lockout interval and basal rate should be adjusted based on individual patient needs and response to treatment.
• It is essential to monitor patients closely for signs of respiratory depression, sedation, and other adverse effects when using PCA with hydromorphone.

Evidence-Based Rationale

• The study recommends hydromorphone (0.015 mg/kg i.v.) as a comparable, potentially superior, analgesic to morphine (0.1 mg/kg i.v.) for acute severe pain in the emergency department 1.
• Hydromorphone is comparable in cost to morphine and has a quicker onset of action, making it a suitable choice for PCA use 1.
• The use of PCA with hydromorphone allows patients to self-administer medication as needed, which can improve pain management and reduce the risk of adverse effects 1.

From the FDA Drug Label

2.2 Initial Dosage Use of Hydromorphone Hydrochloride Injection as the First Opioid Analgesic Intravenous Administration Initiate treatment in a dosing range of 0.2 mg to 1 mg every 2 to 3 hours as necessary for pain control, and at the lowest dose necessary to achieve adequate analgesia.

The FDA drug label does not provide a specific hydromorphone rate for Patient-Controlled Analgesia (PCA). However, it does provide guidance on initial dosing ranges for intravenous administration, which can be used as a starting point for PCA.

• The initial dose for intravenous administration is in the range of 0.2 mg to 1 mg every 2 to 3 hours as necessary for pain control.
• The dose should be titrated based on the individual patient's response to achieve acceptable pain management and tolerable adverse events 2.
• It is essential to use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals.

From the Research

Hydromorphone Dosage for Patient-Controlled Analgesia (PCA)

• The optimal dosage of hydromorphone for PCA varies depending on the patient population and the specific clinical context 3, 4, 5, 6, 7.
• In a study comparing PCA with non-PCA hydromorphone titration for severe cancer pain, the PCA pump was set to deliver a hydromorphone bolus dose of 10% to 20% of the total previous 24-hour equianalgesic dose for opioid-tolerant patients, or 0.5 mg for opioid-naïve patients 3.
• Another study on postoperative pain therapy with hydromorphone used a bolus dose of 0.2 mg for standard PCA, while the target-controlled infusion (TCI-PCA) group had target plasma concentrations between 0.8 and 10 ng/mL 4.
• A prospective survey of patient-controlled epidural analgesia with bupivacaine and hydromorphone in postoperative orthopedic patients used an initial bolus dose of 4 mL (containing 0.06% bupivacaine and 10 microg/mL hydromorphone), with a lockout interval of 10 minutes and a background infusion of 4 mL/hour 5.
• A study on TCI-PCA with hydromorphone in postoperative pain therapy used a hydromorphone dose of 0.26 mg/hour (range 0.07-0.93 mg/hour) during the TCI-PCA period, with a maximum plasma target concentration of 2.3 ng/mL (range 0.9-7.0 ng/mL) 6.
• A multidimensional comparison of morphine and hydromorphone PCA found that both medications provided adequate analgesia without a significant difference in side effects, but hydromorphone was associated with improved mood and less anger/hostility 7.

Key Considerations

• The choice of hydromorphone dosage for PCA should be individualized based on the patient's medical history, current pain level, and opioid tolerance status 3, 4, 5, 6, 7.
• Close monitoring of the patient's pain level, vital signs, and potential side effects is essential to ensure safe and effective use of PCA with hydromorphone 3, 4, 5, 6, 7.
• Further studies are needed to establish the optimal dosage and administration protocols for hydromorphone PCA in different clinical contexts 4, 6.
