You will be closely watched as you return to full consciousness. You should be able to return home within an hour or two after your procedure. Plan to have someone stay with you for at least a few hours. Depending on the reason for your sedation, you may receive more directions. For example, you may need to keep the area of a surgical incision elevated. Side effects like headache and nausea often go away quickly. But tell your healthcare provider if they persist.
Depending on the type of procedure you had, you may need to take pain medicine. You can usually go back to a normal diet and most of your regular activities soon after the procedure. Be sure to follow all after-care instructions. Also take any medicine as directed. Depending on your procedure, you may need more treatments or follow-up procedures.
Health Home Treatments, Tests and Therapies. Why might I need procedural sedation? Some procedures that use this type of sedation include: Bone or joint realignment to fix a broken bone or dislocated joint Breast biopsy to evaluate a lump in the breast Bronchoscopy to evaluate lung conditions Dental surgery Electrical cardioversion to restore a normal heart rhythm Endoscopy for gastrointestinal problems Lumbar puncture to check for neurological disease Minor foot or skin surgery What are the risks for procedural sedation?
Some possible side effects are: Changes in heart rate and blood pressure rare Decreased rate of breathing Headache Inhalation of stomach contents into your lungs rare Nausea and vomiting Unpleasant memory of the experience Side effects are usually not serious. How do I prepare for procedural sedation?
Beforehand, let your healthcare provider know about the following: Your medical history Any past problems with sedation or anesthesia Any recent symptoms, such as a sudden fever Any medicine you are taking, including over-the-counter drugs, such as aspirin If needed, you should stop smoking before your procedure. These might include: Basic blood work to check for anemia and infection Chest X-ray to view your heart and lungs ECG or EKG to check your heart rhythm What happens during procedural sedation?
In general, you can expect the following: You will be given medicine through an IV line often through a vein in your arm. Or you may receive a shot. The medicine may also be given by mouth or by inhalation. If you receive medicine through an IV, you may feel the effects very quickly.
You should start to feel relaxed and drowsy. Your breathing and blood pressure may drop a little. One hundred sixty-two patients were randomized to a continuous infusion of low-dose ketamine 0. There was no difference in opioid consumption between groups. Their funnel plot revealed a large publication bias with trials reporting predominantly positive results.
The findings suggested that the use of volatile agent sedation might be useful in postoperative patients requiring short-term ventilation, and a well-conducted research trial is required. Alternative methods of sedative delivery may be needed in the not too distant future [ 45 ]. A multi-centre, randomized controlled trial compared enteral versus intravenous sedation [ 46 ].
Three hundred and forty-eight patients from 12 Italian ICUs were randomized to receive either midazolam or propofol infused, or hydroxyzine, lorazepam, and melatonin enterally for sedation. This was a superiority trial. Half of the patients in the enteral sedation group had protocol violations so the groups were not adequately separated. Interestingly there were more unplanned extubations in the enteral sedation group but did not need reintubation, and the enteral sedation group received more enteral nutrition.
Hospitals have been overwhelmed with critically ill patients generally resulting a lower skilled nurse to patient ratio. More patients require longer periods of ventilation, use of neuromuscular drugs, and proning with deep sedation. There are reported shortages of commonly used sedative drugs.
A multinational, multi-centre cohort study involving 69 ICUs in 14 countries collected data on patients [ 48 ]. Clinical trials to date do not fully support the use of dexmedetomidine other than to manage agitation. Meantime, more attention is being paid to older drugs in common, e. Knowledge translated into guidelines and protocols are all very well, but studies need to look at translating evidence into practice.

Abstract Purpose of Review This narrative review illustrates literature over the last 5 years relating to sedation delivery to mechanically ventilated adult patients in intensive care units. Recent Findings There has been an increase in dexmedetomidine-related publications but although systematic reviews suggest dexmedetomidine reduces delirium, agitation, and length of stay, clinical trials have not supported these findings.
Summary Research trials have mainly focused on individual drugs rather than practice. Introduction All evidence-based international guidelines regarding sedation for mechanically ventilated patients in intensive care are consistent in their recommendations.
Guidelines A number of guidelines or bundles of care were designed or updated to guide clinicians in consistent delivery of optimal sedation to mechanically ventilated critically ill patients.
BIS Bispectral index BIS monitors, based on the processing of electroencephalographic signals, have reported benefits in the operating theatre and may overcome the restraints of sedation scales during deep sedation or during paralysis. Open in a separate window. Alpha Agonists Clonidine There is a paucity of evidence to support the use of clonidine because of a lack of controlled trials in critically ill adults. Dexmedetomidine A disproportionate number of dexmedetomidine-related systematic reviews and meta-analyses in critically ill ventilated patients of variable quality were published covering different patient populations and outcomes.
Dexmedetomidine and Light Sedation Early deep sedation is an independent predictor of time to extubation, hospital death, and day mortality. Dexmedetomidine and Sleep One study investigated the effect of enteral dexmedetomidine on sleep polysomnography in 15 participants [ 41 ].
Other Drugs and Routes The N-methyl-d-aspartate receptor antagonist ketamine has also been shown to have analgesic properties, along with bronchodilatory effects and cardiovascular stimulation. Conclusion Clinical trials to date do not fully support the use of dexmedetomidine other than to manage agitation.

While some operations require the patient to be semi-responsive to pain or voice stimulation, others may temporarily desensitize the whole body, preventing it from feeling pain at all for the duration of the procedure. For major surgeries, a general anesthesia may be used that makes the patient unresponsive to even highly painful stimulants.
Recent press has given a lot of concern to the use of the drug propofol. This drug, when used in the right situations under appropriate monitoring by a trained anesthesiologist is safe for use in cases of deep sedation and is often employed for patients who cannot tolerate standard monitored sedation techniques. In addition to practicing traditional bowel prep methods, a patient must also be sedated before a colonoscopy procedure can effectively take place.
