Professionals', patients' and families' views on the use of opioids for chronic breathlessness: A systematic review using the framework method and pillar process.
In combination with non-pharmacological interventions, opioids may safely reduce chronic breathlessness in patients with severe illness. However, implementation in clinical practice varies. ⋯ There are significant barriers and enablers to the use of opioids for the symptomatic reduction of chronic breathlessness based on the knowledge, views and attitudes of clinicians, patients and families. Clinicians' interactions with patients and their families strongly influences adherence with opioid treatment regimens for chronic breathlessness. Clinicians', patients' and families' knowledge about the delicate balance between benefits and risks is generally poor. Education for all, but particularly clinicians, is likely to be a necessary (but insufficient) factor for improving implementation in practice.

The intraoperative dosing of opioids is a challenge in routine anesthesia as the potential effects of intraoperative overdosing and underdosing are not completely understood. In recent years an increasing number of monitors were approved, which were developed for the detection of intraoperative nociception and therefore should enable a better control of opioid titration. The nociception monitoring devices use either continuous hemodynamic, galvanic or thermal biosignals reflecting the balance between parasympathetic and sympathetic activity, measure the pupil dilatation reflex or the nociceptive flexor reflex as a reflexive response to application of standardized nociceptive stimulation. ⋯ There is an ongoing discussion about the clinical relevance of nociceptive stimulation in general anesthesia and the effect on patient outcome. Initial results for individual monitor systems show a reduction in opioid consumption and in postoperative pain level. Nevertheless, current evidence does not enable the routine use of nociception monitoring devices to be recommended as a clear beneficial effect on long-term outcome has not yet been proven.

Opioid Use Increases the Risk of Delirium in Critically Ill Adults Independently of Pain.
Rationale: It is unclear whether opioid use increases the risk of ICU delirium. Prior studies have not accounted for confounding, including daily severity of illness, pain, and competing events that may preclude delirium detection. Objectives: To evaluate the association between ICU opioid exposure, opioid dose, and delirium occurrence. ⋯ Any opioid administration in awake patients without delirium was associated with an increased risk for delirium the next day [OR, 1.45; 95% CI, 1.24-1.69]. Each daily 10-mg intravenous morphine-equivalent dose was associated with a 2.4% increased risk for delirium the next day. Conclusions: The receipt of an opioid in the ICU increases the odds of transitioning to delirium in a dose-dependent fashion.

An assessment of opioids on respiratory depression in children with and without obstructive sleep apnea.
Obstructive sleep apnea is a risk factor for respiratory depression following opioid administration as well as opioid-induced hyperalgesia. Little is known on how obstructive sleep apnea status is associated with central ventilatory depression in pediatric surgical patients given a single dose of fentanyl. ⋯ In pediatric surgical patients, obstructive sleep apnea status was not associated with significant differences in central respiratory depression following a single dose of fentanyl (1 mcg/kg). These findings can help determine safe opioid doses in future pediatric obstructive sleep apneapatients.
