Analysis of indwelling catheter placement in the timing of general anesthesia operation patients' comfort effects

Objective To observe the operation of general anesthesia with tracheal intubation in patients with indwelling catheter on heart rate,mean arterial pressure and the comfortable degrees. Methods Elective thoracic operation,tracheal intubation general anesthesia operation for patients with indwelling catheter time undertook comparative study,200 cases were randomly divided into two groups:general anesthesia before urethral catheterization group,urethral catheterization before and after general anesthesia group. Anesthesia before urethral catheterization before anesthesia group at 15 min indwelling catheter after urethral catheterization,anesthesia groups in tracheal intubation after indwelling catheter. Results In general anesthesia group after catheterization heart rate,mean arterial pressure and comfort than the control group,there were significant differences. Conclusion Urethral catheterization before and after general anesthesia can alleviate the discomfort of urethral catheterization for patients with indwelling catheter operation,optimal timing.
