Postoperative Pain Management for Left Hand Contracture Surgery

Oxycodone Prescribing Guidelines

The British Journal of Anaesthesia recommends prescribing no more than 5-7 days of immediate-release oxycodone, with dosing age-related rather than weight-based and considering renal function 2, 5, 1
Modified-release oxycodone preparations should be avoided without specialist consultation, according to the British Journal of Anaesthesia 5, 1

Sedation scores should be recorded alongside respiratory rate to detect risk of opioid-induced ventilatory impairment, as recommended by the British Journal of Anaesthesia 1
When analgesic requirements decrease, a reverse analgesic ladder should be followed, weaning opioids first, then stopping NSAIDs, and finally stopping acetaminophen, according to the British Journal of Anaesthesia 2

Patients should receive clear instructions on how to safely self-administer opioids, wean analgesics, and dispose of unused medication, as recommended by the British Journal of Anaesthesia 5
The discharge letter must explicitly state the recommended opioid dose and planned duration, and patients should be encouraged to keep a record of analgesics taken, according to the British Journal of Anaesthesia 5

For patients already on buprenorphine therapy, management is more complex and requires coordination with their buprenorphine provider, as suggested by the British Journal of Anaesthesia 6, 7, 8
For elderly patients or those with renal impairment, alternative opioids may be more appropriate than oxycodone, according to the British Journal of Anaesthesia 2
Patients should be warned about the dangers of driving or operating machinery while taking opioid medications, as recommended by the British Journal of Anaesthesia 5

Both hydromorphone (Dilaudid) and oxycodone (the opioid component of Percocet) are full mu-opioid receptor agonists that work through the same mechanism without competitive antagonism, allowing for safe sequential use in postoperative pain management 9.
Full mu-agonists do not block or interfere with each other's analgesic effects, making them suitable for combination or sequential use in postoperative pain management 9.
The transition between different full mu-agonist opioids is standard practice in postoperative pain management, with studies demonstrating safe sequential use of morphine followed by oxycodone without specified waiting periods 10, 11.

The timing of opioid administration should be based on clinical need for analgesia rather than arbitrary waiting periods between doses, as recommended by the American Medical Association 12, 11.
Consider administering Percocet when the previous Dilaudid dose begins to wear off (typically 2-4 hours for IV hydromorphone) to maintain continuous pain control, as suggested by the Anaesthesia journal 10, 11.
Incorporate acetaminophen (already present in Percocet) as the foundation of your pain regimen, which provides opioid-sparing effects without requiring timing considerations, as recommended by JAMA Surgery 12.
Implement gabapentin or pregabalin for additional opioid-sparing effects in the postoperative period, as suggested by JAMA Surgery 12.

The key concern is cumulative opioid effect and respiratory depression risk, not drug-drug antagonism, as highlighted by JAMA Surgery 12.
Monitor sedation scores alongside respiratory rate to detect opioid-induced ventilatory impairment, as recommended by JAMA Surgery 12.
Do not withhold necessary analgesia based on misconceptions about required waiting periods between different opioids, as this leads to inadequate pain control and patient suffering, as warned by Anaesthesia 10, 11.
Do not forget to account for the acetaminophen component in Percocet (typically 325mg per tablet) to avoid exceeding 4000mg daily total acetaminophen dose, as cautioned by JAMA Surgery and Anaesthesia 12, 11.

In postoperative patients who have received intrathecal hydromorphone, scheduled oral acetaminophen combined with a non‑steroidal anti‑inflammatory drug (or a COX‑2 selective inhibitor) should be started immediately after surgery and continued throughout recovery to provide baseline analgesia and reduce the need for systemic opioids. 13
Intravenous dexamethasone administered intraoperatively (standard adult dose) adds analgesic and anti‑emetic benefit without diminishing the effect of intrathecal hydromorphone, supporting better pain control in the early postoperative period. 13

Routine monitoring for pruritus and postoperative nausea/vomiting is essential because these adverse effects are common after intrathecal opioid administration and can delay early mobilization, even when low intrathecal doses are used. [14][15]

When basic multimodal analgesia is insufficient or contraindicated, a fascia‑iliaca block or local infiltration analgesia should be considered as adjuncts to improve postoperative pain control. 13
A single‑injection local infiltration technique provides effective analgesia without notable side‑effects and may be employed as an additional option in the multimodal plan. [15][16]

Epidural analgesia, femoral nerve block, and lumbar plexus block are not recommended as rescue modalities for patients already receiving intrathecal hydromorphone because the potential harms (e.g., limb weakness, bladder dysfunction, delayed ambulation) outweigh any analgesic benefit. [14][15]16
