Procedural Sedation & Acute Pain
Balance comfort with airway safety and use a monitored, individual analgesic plan.
Quick revision ↓ Medical Dictionary
01Sedation is a continuum
Minimal, moderate and deep sedation differ in responsiveness and physiological effects. A patient can unintentionally become more deeply sedated than planned. Staff must be able to recognise and rescue deterioration, with monitoring and equipment suited to the patient and procedure.
02Prepare the encounter
Assess airway, comorbidity, medicines, prior reactions and the procedure’s urgency. Discuss consent, fasting and aspiration risk under the relevant protocol. Allocate clear roles for procedural work and monitoring; distraction from the patient can delay recognition of airway obstruction or apnoea.
03Multimodal analgesia
Combine suitable methods with different mechanisms when appropriate, including non-drug measures and regional techniques. Match treatment to pain source, organ function and risks. Pain relief should enable breathing and movement where possible rather than simply achieve a lower number with excessive sedation.
04Opioid safety
Opioids can impair ventilation, especially with other sedatives or sleep-disordered breathing. Monitor consciousness and breathing, and review renal function and accumulation risks. Patient-controlled analgesia requires appropriate selection and instruction; another person pressing the button defeats an important safety feature.
05Recovery and discharge
Recovery criteria include stable physiology, appropriate alertness, controlled symptoms and a safe discharge arrangement. Drug effects may recur after a reversal agent wears off. Provide activity, escort and return instructions according to the technique and local policy, with an accessible contact route.
High-Yield Revision
- Sedation can deepen unexpectedly.
- Analgesia should improve function without excessive sedation.
- Recovery continues after the procedure ends.
Common Pitfalls
- Allowing proxy activation of patient-controlled analgesia.
- Discharging immediately after reversal without observation.
