The time of clinical onset and duration of action following single-dose administration is primarily related to lipid solubility.

Morphine, Fentanyl, Meperidine, Methadone, Hydromorphone, Codeine, Alfentanil Opioid agonists bind to specific opioid receptors (primarily µ receptors) distributed throughout the neuraxis.

Seven of these responses were excluded from further analysis; five were high dependency units that do not admit ventilated patients, and two questionnaires were returned blank.

The denominator used for the results and statistical analysis was 185.

Opioids inhibit spontaneous neuronal firing and excitatory neurotransmitter release.

The majority of units have a written sedation guideline (80%), and 78% state that daily sedation holding is practiced.BNZs enhance gamma-aminobutyric acid (GABA) neurotransmission by binding to specific BNZ receptors on the GABAA receptor complex.They enhance chloride flux across ligand-gated chloride channels, resulting in membrane hyperpolarization and inhibition of the action potential.A wide variety of sedating agents is used, with the choice of agent largely determined by the duration of action rather than cost. Over-sedation can contribute to hypotension, venous thrombosis, prolonged ventilation, an increased risk for pneumonia and a prolonged stay in the ICU, with an increasing burden on staff, bed availability and associated costs [], in 2000, demonstrated that daily interruption of sedation reduced ventilation duration, ICU length of stay, complications such as venous thromboembolic disease, upper gastrointestinal bleeding and bacteraemia, and the incidence of post-traumatic stress disorder [], before the concept of daily sedation holding was published.The most frequently used agents were propofol and alfentanil for short-term sedation; propofol, midazolam and morphine for longer sedation; and propofol for weaning purposes. The rate of implementation of current sedation guidelines in UK ICUs is unknown.
