ObjectiveTo evaluate the risk factors for postoperative indwelling catheter following enhanced recovery after primary unilateral total knee arthroplasty (TKA) under general anesthesia.MethodsPatients who underwent primary unilateral TKA under general anesthesia between January 2017 and August 2018 were enrolled in the study. Among them, 205 patients who met the selection criteria were included in the study, and the clinical data were collected, including gender, age, body mass index, preoperative range of motion, Hospital for Special Surgery (HSS) score, American Society of Anesthesiologists (ASA) score, disease type, comorbidity, hemoglobin, hematocrit, blood volume, length of operation and operation time, whether to keep drainage after surgery, intraoperative blood loss, total blood loss, and preoperative, intraoperative, postoperative fluid infusions, and total fluid infusion on the day of surgery, urine volume on the day of surgery. Univariate analysis and logistic regression analysis were used to screen the risk factors for postoperative indwelling catheter. Length of stay and incidences of complications (intermuscular vein thrombosis, deep vein thrombosis, pulmonary embolism, incision swelling and exudation, electrolyte disorder, nausea and vomiting, and urinary tract infection) were compared between the patients with or without indwelling catheter.ResultsIndwelling catheter occurred in 41 (20%) of 205 patients. Single factor analysis showed that the influence factors were age, gender, keeping drainage after surgery, total fluid infusion and urine volume on the day of surgery (P<0.05). The multiple factors analysis showed that the males and more urine volume on the day of surgery were the significant risk factors for indwelling catheter after primary TKA (P<0.05). In addition, postoperative length of stay was shorter and the incidence of urinary tract infection was lower in non-indwelling catheter group than in indwelling catheter group, showing significant differences (P<0.05).ConclusionThe male patients with more urine on the day of surgery have higher risk for indwelling catheter after primary unilateral TKA under general anesthesia with an enhanced recovery program.
ObjectiveTo explore the influence of evidence-based nursing care of catheterization on the incidence of urinary tract injury and urinary tract infection in patients with spinal cord injury and long-term indwelling catheters.MethodsFrom July 1st, 2017 to November 30th, 2018, 100 patients with spinal cord injury indwelling catheters in Department of Spinal Surgery were prospectively selected as the research objects. According to the admission time, patients admitted between July 2017 and February 2018 were assigned into the control group (n=50), and patients admitted between March 2018 and November 2018 were assigned into the observation group (n=50). Traditional catheter placement was used in the control group, while evidence-based catheter placement was used in the observation group. The incidences of catheter-related urethral injury and urinary tract infection after the catheterization were compared between the two groups.ResultsThere was no statistically significant difference in gender, age, diagnosis, or length of hospital stay between the two groups (P>0.05). Catheter placement was performed 57 times in the control group and 59 times in the observation group during hospitalization. After catheterization, the incidences of urethral hemorrhage and gross hematuria in the control group [22.80% (13/57) and 15.78% (9/57), respectively] were higher than those in the observation group [both were 1.69% (1/59)], with statistical differences between the two groups (P<0.05). The incidence of urinary tract infection in the control group differed from that in the observation group [42.0% (21/50) vs. 18.0% (9/50), P=0.009].ConclusionThe evidence-based urinary catheterization method for patients with spinal cord injury and long-term indwelling catheter can effectively prevent catheter-related urinary tract injury, reduce the incidence of catheter-related urinary tract infection during hospitalization, and improve the quality of clinical care.
Objective To explore the timing of indwelling urinary catheter removal in male patients undergoing orthopedic surgery under general anesthesia by a prospective randomized controlled study. Methods Male patients who underwent orthopedic surgery under general anesthesia in the First People’s Hospital of Shuangliu District between September 2019 and January 2021 were selected prospectively. The patients were randomly assigned to group A (pull out the catheter before anesthesia) and group B (pull out the catheter within 24 hours after anesthesia) at a ratio of 1∶1 by sortition. The age, operation duration, operation site, heart rate when pulling out the catheter, first urination, urinary tract infection, patient comfort score, nursing satisfaction score and patient satisfaction related indicators of the two groups were recorded and analyzed. Results A total of 120 patients were included in the study. All patients successfully completed the trial without dropping out or quitting. There was no significant difference between the two groups in terms of age, operation duration and operation site (P>0.05). No urinary tract infection occurred in both groups. There was no significant difference in the first urination between the two groups (P>0.05). The heart rate of patients in group A when pulling out the catheter was slower than that of group B [(74.62 ± 11.38) vs. (84.52 ± 8.98) times/min], and the satisfaction of patients in group A (group A: 46 cases were satisfied, 11 cases were relatively satisfied, 3 cases were dissatisfied; group B: 17 cases were satisfied, 25 cases were relatively satisfied, 18 cases were dissatisfied), comfort score (17.82±2.73 vs. 16.68±2.13), and nursing satisfaction score (19.62±1.59 vs. 16.32±2.05) were better than those in group B (P<0.05). Conclusions For male patients who need catheterization before orthopedic surgery under general anesthesia, pulling out the catheter before waking up after anesthesia can effectively reduce the physiological stress reaction of patients, reduce discomfort, improve patient satisfaction, and reduce the workload of nurses after surgery, which is conducive to early rehabilitation exercise of patients.
