why are sedative given after an operation?
post op seds are to prevent the pt from becoming a stiff by pulling out the stitches
Usually to relieve any pain and put together you relax so your body can re-coup after the surgery, hydrocodone is popular...although it really depends on your doctor. If a med relaxes you it takes any your strain and vice versa.
after most operations relations will receive analgesics such as morphine and fentanyl to take away throbbing, but somtimes people may not know how to breathe by themselves with out the ventilator, when this happen patients are given "sedatives" to help them preserve calm and consent to them "rest". Common sedatives include propofol for longer occupancy sedation, other types include the benzodiazepines ativan and versed.
We don't usually give patients sedative after surgery. We give affliction medicines, and some of those can be sedating, but the aim is pain nouns, not sedation. They may also get a muscle relaxant to assistance with soreness from muscle spasms, and those can be sedating as economically.
Sometimes, if a person wake up wild, we will make a contribution a sedative such as Versed or Ativan to relaxed them down. If someone requires postoperative ventilation, or other mortified ICU care, he may be sedated to allow his body to regain your strength without unnecessary movement and increased blood pressure and heart rate cause by the stress of the breathing tube (or whatever is uncomfortable)
