Answer:
Benzodiazepines enhance pain relief attained with opioids and cause sedation.
Explanation:
Systemic analgesia is considered an alternative method and is indicated when there are contraindications to regional blocks or in the absence of resources to perform them. Analgesics can be administered by various routes, such as intramuscular, inhalation and intravenous, but the latter allows rapid therapeutic effect and, consequently, dose titration. In systemic analgesia benzodiazepines increase pain relief obtained with opioids and cause sedation, leaving the patient totally unconscious.
