If you are planning to have an amputation, your doctor will review a list of possible complications, which may include:
Poor healing at amputation site, resulting in the need for a higher level of amputationSkin breakdownInfectionBleedingSwelling at surgical sitePhantom limb pain—feeling pain in amputated limb area
Phantom sensation—feeling that amputated limb is still thereBlood clotsComplications of anesthesia
Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as: SmokingDrinkingChronic diseases, such as diabetes or obesity
Your amputation may be planned. In this case, your doctor will review with you how it is done and what to expect. An emergency amputation may need to be done. This can happen because of trauma or life-threatening infection. In this case, you may not have this preparation.
Depending on the injury and location, your doctor may do some of the following before your surgery:
Imaging studies to look at the bones and surrounding tissue for evidence and location of disease or trauma, including:
X-raysCT scanMRI scanBone scanTissue culturesBlood testsHeart evaluationPreoperative antibioticsTests to evaluate blood flow in the part of the body that is being amputated
Leading up to your surgery:
Arrange for a ride home from the hospital.Arrange for help at home after your surgery.Follow instructions for eating before surgery—usually nothing after midnight.You may be asked to use an antibacterial soap the morning of your surgery.
This will depend on the body part operated on. You may receive:
General anesthesia—You will be asleep.
Local anesthesia—A specific area will be numbed.Spinal anesthesia—Your lower body will be numb.
An incision will be made into the skin of the affected limb or limb part. If needed, the muscles will also be cut. Blood vessels will be tied off or sealed to prevent bleeding. The bone will then be cut through. The diseased or damaged body part will be removed.
Muscle will be pulled over the bone. It will be sutured in place there. The remaining skin will be pulled over the muscle. The skin will be sewn to form a stump. A sterile dressing will be placed over the incision.
If severe infection is involved, the incision may be left open to heal.
This procedure can take 20 minutes to several hours. The length will depend on the type of amputation being done and your overall state of health.
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
