Catheter-related bladder discomfort (CRBD) is not uncommon in male patients under general anesthesia, and it may cause patient agitation and exacerbated postoperative pain. In this study, the investigators will enroll male patients undergoing elective colonal and rectal surgery with surgical duration of at least 2 h, requiring catheterization of the urinary bladder with urinary catheterization after anesthetic induction, and compare preoperative education with image illustrations combined with local tetracaine mucilage vs. local tetracaine mucilage alone in alleviating CRBD during the post-operative period.

RECRUITINGThe incidence of postoperative CRBD
The incidence of postoperative CRBD; CRBD was assessed according to the following scaling system: no CRBD; mild CRBD (complaint about CRBD on questioning only); moderate CRBD (complaint about CRBD without enquiring); and severe CRBD (complaint about CRBD without enquiring, with urinary urgency demonstrated by a spontaneous behavioural response such as flailing limb, verbal responses, or attempt to remove the catheter)
Time frame: 6 hours
The severity of postoperative CRBD
The severity of CRBD was assessed according to the following scaling system: no CRBD; mild CRBD (complaint about CRBD on questioning only); moderate CRBD (complaint about CRBD without enquiring); and severe CRBD (complaint about CRBD without enquiring, with urinary urgency demonstrated by a spontaneous behavioural response such as flailing limb, verbal responses, or attempt to remove the catheter)
Time frame: 6 hours
The incidence of emergence agitation
Using Riker Sedation-Agitation Scale, where 5 to 7 represents agitation and 1 to 3 represents deep sedation
Time frame: 6 hours
The incidence of postoperative pain
The incidence of postoperative pain;Using a visual analog scale (VAS) score of 0-10, where 0 represents no pain and 10 represents worst imaginable pain.
Time frame: 6 hours
The severity of postoperative pain
Using a visual analog scale (VAS) score of 0-10, where 0 represents no pain and 10 represents worst imaginable pain.
Time frame: 6 hours
Incidenc of adverse events
Incidenc of adverse events, such asrespiratory depression (SpO2\<90%), deep sedation, and toxicity of tetracaine
Time frame: 6 hours
