Orthopedics department of five-yi middle hospital in Jiangmen city
2. Application object
During 2017 to 2018, in orthopaedics of Wuyi Hospital in Jiangmen, 120 cases of patients with knee osteoarthritis, which are subjected to parallel unilateral total knee arthroplasty and are free from complications, are randomly divided into 2 groups of 60 patients. Wherein,
observation group (using the drainage bag in the above embodiment of the invention): 20 men and 40 women, age 40-82 years, 32 left knees and 28 right knees;
control group (using commercially available spring negative pressure drainage bag): 21 men and 39 women, ages 42-80, 35 left knees and 25 right knees.
The gender, age and disease condition of the two groups of patients have no significant difference.
Application method
(1) The treatment method comprises the following steps:
observation group (using the drainage bag in the above embodiment of the invention): after unilateral total knee replacement, a drainage tube is reserved, and the drainage tube is clamped by a clamp. After 4h, squeezing the negative pressure bottle to discharge the gas in the bottle as much as possible, then opening the clamp and stopping squeezing the negative pressure bottle to conduct negative pressure drainage. Recording the accumulated liquid in the negative pressure bottle every 2 hours within 6 hours from the beginning of drainage, and immediately performing negative pressure drainage operation (namely squeezing the negative pressure bottle to discharge the accumulated liquid in the bottle into a capacity bag, and then stopping squeezing to continue negative pressure drainage); recording the accumulated liquid in the negative pressure bottle every 6 hours between 6 hours and 24 hours from the beginning of drainage, and immediately performing negative pressure drainage operation once after recording; after 24 hours from the start of drainage, the amount of accumulated liquid in the negative pressure bottle was recorded every 12 hours, and a negative pressure drainage operation was performed immediately after the recording. In principle, the drainage bag is replaced every 24 hours, but if the drainage bag is full in 24 hours, the drainage bag is replaced at any time. Measuring and recording the total amount of effusion drained every 24 hours from the beginning of drainage (opening a drain valve at the bottom of a capacity bag, collecting and measuring by using a measuring cup); when the drainage rate is lower than 50mL in 24h, the drainage tube is pulled out, and drainage is finished.
Control group (model A1000 ml … …, manufactured by Hua Kangwei Material Co., ltd., new county, using a commercially available spring negative pressure drainage bag): after unilateral total knee replacement, a drainage tube is reserved, and the drainage tube is clamped by a clamp. After 4h, the spring is extruded until the spring is completely deformed, the clamp is opened, the spring is loosened, and negative pressure drainage is carried out. From the beginning of drainage, the accumulated liquid volume is recorded at fixed time (note: because the spring negative pressure drainage bag can not measure in real time, the medical staff judges approximate quantity based on visual inspection by experience), and the recorded time interval is the same as that of the observation group. In principle, the drainage bag is replaced every 24 hours, but the drainage bag is replaced at any time if the drainage bag is full or the negative pressure of the drainage bag is lost in 24 hours. Measuring and recording the total amount of effusion drained every 24 hours from the beginning of drainage (opening a drain valve at the bottom of a drainage bag, collecting and measuring by using a measuring cup); when the drainage rate is lower than 50mL in 24h, the drainage tube is pulled out, and drainage is finished.
Both groups of patients after operation are treated with conventional hemostasis, pain relieving, anti-infection, antithrombotic and the like, and conventional negative pressure drainage nursing is carried out during drainage. The operation methods, postoperative drug treatment, nursing and rehabilitation training of the two groups of patients are not significantly different.
(2) And (3) observing the indexes: observing and comparing two groups of indexes such as total drainage volume, continuous drainage time, average hospitalization days and the like; comparing the treatment effectiveness of the two groups of patients with the satisfaction of the patients; and comparing the complications of infection, drainage blood loss, neurovascular injury, joint swelling and the like of the two groups of patients within 5 days after operation.
(3) Evaluation of curative effect: the short-term efficacy was evaluated at an active knee flexion angle of the knee joint 5 days after surgery. Improvement: the active knee bending angle of the knee joint is more than or equal to 45 degrees; the method is effective: the active knee bending angle of the knee joint is less than 45 degrees but more than or equal to 30 degrees; invalidation: the active knee bending angle of the knee joint is smaller than 30 degrees.
Application results
The results are shown in tables 1-3.
The results show that the drainage effect after the joint replacement operation of the observation group is better than that of the control group. The total drainage amount of the patients in the observation group is smaller than that of the patients in the control group, the drainage duration is also shorter, the average hospitalization time of the patients is shortened, the hospitalization cost is saved, and most of the patients are satisfied with the evaluation of the treatment. From the aspect of clinical treatment effect and complications, the total clinical effective rate of the observation group is 95.00 percent, which is far higher than that of the control group, the total occurrence rate of the observation group complications is 6.67 percent, which is obviously lower than that of the control group, thus the invention is safe and effective and is more economical than the spring negative pressure drainage bag.
It is worth mentioning that the negative pressure drainage bag is more convenient and accurate in observing the drainage quantity of 6 hours after operation, and is helpful for medical staff to judge the bleeding condition of patients after operation timely and accurately.
