Influence of extubation time of urinary catheter on post-operational urination and comfort degree of patients with orthopedic surgery

Objective To explore the influence of extubation time of urinary catheter on post-operational urination and comfort degree of patients with orthopedic surgery, so as to and make clear the best extubation time of urinary catheter for them. Methods 900 patients treated with operation in Department of Orthopaedics in the Third Hospital of Hebei Medical University from April to June in 2016 were selected by convenience sampling and divided, according to extubation time of urinary catheter, into group A, B and C, each with 300 cases. For patients in group A, urinary catheters were removed in the morning the day after the operation (12~24 h after operation) , while in group B, 6 h after, and in group C, 2 h after. Rate of successful urination after extubation of urinary catheter, bladder discomfort, incidence rate of acute urinary retention and comfort degree of indwelling catheter in the three groups were compared. Results Difference in rate of successful urination and incidence rate of frequent micturition, urgent urination, micturition pain and acute urinary retention of patients in the three groups showed statistic significance (P<0.05). It was shown in pairwise comparison that rates of successful urination in group A and B were higher than that in group C, while incidence rates of acute urinary retention were lower (P<0.05), and that incidence rate of frequent micturition, urgent urination and micturition pain in group A was higher than that in group B and C (P<0.05). Difference in comfort degree of indwelling catheter in the three groups showed statistic significance (P<0.05). Incidence rates of discomfort in degree II in group B and C were less than that in group A, while incidence rate of discomfort in degree III in group C was less than that in group A and B (P<0.05). Conclusions For orthopedic patients, the best extubation time of urinary catheter is 6 h after the operation, which helps to raise rate of successful urination, lower urethra irritative symptoms due to cathetering, and reduce bladder discomfort after extubation.
