What to Expect After THR Surgery
A total hip joint replacement takes approximately two to four hours of surgical time. The preparation prior to surgery may take additional hours. After surgery, the patient is taken to a recovery room for immediate observation which generally lasts between one to four hours. The lower extremities will be closely observed for both adequate sensation and circulation. If unusual symptoms of numbness or tingling are noted by the patient, recovery room nurses are available and should be notified by the patient. Upon stabilization, the patient is transferred to a hospital room.
During the immediate recovery period, patients are given intravenous fluids. Intravenous fluids are important to maintain a patient’s electrolytes as well as for administering antibiotics. Patients also will notice tubes draining fluid from the surgical wound site. The amount and character of the drainage is important to the doctor and can be monitored closely by the nurse in attendance. A dressing is applied in the operating room and will remain in place for two to four days to be later changed by the attending surgeon and staff.
Pain control medications are commonly given through a patient-controlled analgesia (PCA) pump whereby patients can actually administer their own dose of medications on demand. Pain medications occasionally can cause nausea and vomiting. Anti-nausea medications may then be given.
Measures are taken to prevent blood clots in the lower extremities. Patients are placed in elastic hose (TEDs) after surgery. Compression stockings are often added which act by squeezing with circulating air in plastic bags wrapped around the legs, forcing blood circulation. Patients are encouraged to actively exercise the lower extremities in order to mobilize venous blood in the lower extremities to prevent blood clots. Medications are often given to thin the blood in order to further prevent blood clots.
Patients may also experience difficulty with urination. This difficulty can be a side effect of medications given for pain. As a result, catheters are often placed into the bladder to allow normal passage of urine.
Immediately after surgery, patients are encouraged to frequently perform deep breathing and coughing in order to avoid lung congestion and the collapse of tiny airways in the lungs. Patients are also given a "blow bottle," whereby active blowing against resistance maintains the opening of the breathing passages.
