Effects Of Psychological Intervention In The Prevention Of Catheter-related Bladder Discomfort In General Anesthesia Patients During Recovery Period

Objective:To investigate the effects of psychological intervention in prevention of catheter-related bladder discomfort(CRBD) in general anesthesia patients during anesthesia recovery period and the appropriate time of psychological intervention.Methods:240patients, who underwent general anesthesia for general surgical operation or orthopedic surgery, were randomly divided into4equal groups of60each. Group A received psychological intervention by anesthetists on preoperative visit; Group B received psychological intervention on preoperative visit and before anesthesia induction; Group C:only had psychological intervention before anesthesia induction and group D received no psychological intervention and served as a control group. Urethral catheterization was performed in all patients after the same procedure of general anesthesia induction, and anesthesia was maintained by intravenous anesthesia after the mechanical control breathing. Heart rate (HR) and mean arterial blood pressure (MAP) were recorded before the anesthesia induction (T0), at the moment of extubation(T1) and after extubation time (T2). Anesthesia time, recovery time and extubation time were recorded. The agitation score, visual analogue scale, and degree of catheter-related bladder discomfort were evaluated after tracheal extubation and patients can accurately answer questions. Incidence of severe catheter-related bladder discomfort in general anesthesia patients during recovery period were compared in four groups.Results:1. There was no statistically significant difference among four groups with respect to gender, age, height, weight, anesthesia time, waking time and extubation time (p>0.05).2. The mean of heart rate and MAP had no statistically significant difference at To, but lower in group A, B, C than group D at T1(p<0.05), slightly lower in group B than group A and C. The mean of MAP and heart rate had no statistically significant difference at T2and To (p>0.05).3. Agitation rate in group A, B, C was significantly lower than group D; Group B was lower than group A and C, but it has no statistical significance; there was no statistical significance between group A and group C. No statistical significance of VAS was found among four groups.4.The severe catheter-related bladder discomfort rate was significantly lower in group A, B, C than group D; lower in Group B than group A and group C; no statistical significance was found between group A and group C. The incidence of mild catheter-related bladder discomfort just the opposite.Conclusion:1. Preoperative psychological intervention can reduce the severe catheter-related bladder discomfort in general anesthesia patients during recovery period, but also reduced the incidence of adverse cardiovascular events, mild CRBD significantly increased, Significantly decreased in patients with general anesthesia of discomfort caused by CRBD awakening period.2. The appropriate timing for implementation of psychological intervention was preoperative implemention and strengthen again before anesthesia induction.
