Randomized Controlled Trial
High dose dexamethasone in high pain responders undergoing total hip arthroplasty: A randomized controlled trial.
Postoperative pain after total hip arthroplasty (THA) may delay postoperative mobilization and discharge. Postoperative pain has been shown to be higher in pain catastrophisers and patients receiving opioids. A single dose of glucocorticoid reduces pain after THA, and an increased dose of glucocorticoids has been found to be effective in patients at high risk of postoperative pain after total knee arthroplasty (TKA), however, the ideal dose in THA remains unknown. ⋯ 1 mg kg -1vs. 0.3 mg kg -1 dexamethasone improved neither postoperative pain nor recovery in THA in a cohort of predicted high pain responders.

Moderate-to-severe pain is common and remains a significant problem. Compared with opioid analgesia alone, single-shot peripheral nerve blockade has been associated with improved pain relief and the potential of decreased side effects. Single-shot nerve blockade, however, is limited by its relatively short duration of action. In this review, we aim to summarize the evidence related to local anaesthetic adjuncts for peripheral nerve blockade. ⋯ Intravenous dexamethasone is the local anaesthetic adjunct of choice, increasing the duration of sensory and motor blockade as well as the duration of analgesia by 477, 289 and 478 min, respectively. In view of this, we recommend consideration of the intravenous administration of dexamethasone at a dose of 0.1-0.2 mg/kg for all patients undergoing surgery whatever the level of postoperative pain, mild, moderate or severe. Further research should focus on the potential synergism of action between intravenous dexamethasone and perineural dexmedetomidine.

ReviewContinuous peripheral nerve blocks for analgesia following painful ambulatory surgery: a review with focus on recent developments in infusion technology.
Continuous peripheral nerve blocks (cPNB) decrease pain scores and opioid consumption while improving patient satisfaction following ambulatory surgery. This review focuses on the history and evolution of ambulatory cPNBs, recent developments in infusion technology that may prolong the duration of analgesia, optimal choice of cPNB for various surgical procedures, and novel analgesic modalities that may prove to be alternatives or supplements to cPNBs. ⋯ Patients undergoing painful ambulatory surgery are likely to have less pain and require fewer opioid analgesics when receiving a cPNB for postoperative analgesia. Advances in electronic pumps used for cPNBs may increase the duration of these benefits.

Prescription of modified-release opioids for acute postoperative pain is widespread despite evidence to show their use may be associated with an increased risk of adverse effects. This systematic review and meta-analysis aimed to examine the available evidence on the safety and efficacy of modified-release, compared with immediate-release, oral opioids for postoperative pain in adults. We searched five electronic databases from 1 January 2003 to 1 January 2023. ⋯ Our narrative synthesis concluded that modified-release opioids showed no superiority over immediate-release opioids for analgesic consumption, length of hospital stay, hospital readmissions or physical function after surgery. One study showed that modified-release opioid use is associated with higher rates of persistent postoperative opioid use compared with immediate-release opioid use. None of the included studies reported on psychological function, costs or quality of life.

Randomized Controlled TrialDelirium in ventilated patients receiving fentanyl and morphine for Analgosedation: Findings from the ANALGESIC trial.
The differential effect of fentanyl vs. morphine analgosedation on the development of hospital inpatient delirium in patients receiving mechanical ventilation is unknown. We aimed to compare the incidence of coding for delirium and antipsychotic medication use in patients treated with fentanyl vs. morphine in the ANALGESIC trial. ⋯ Fentanyl is associated with a higher incidence of hospital inpatient delirium when used for analgosedation compared with morphine, and the dose of opioid is linearly related to the need for antipsychotic medication administration. The role of analgosedation in promoting delirium requires further investigation.
