Abstract
Background Intraoperative catheterization often leads to postoperative catheter-related bladder discomfort (CRBD) during the restoration period. This study aimed to assess the curative effect of butorphanol as a K receptor agonist in the treatment of postoperative CRBD. Patients and Approaches. Sixty patients with CRBD who underwent elective nonurological surgery at the postanesthesia care unit were randomly and evenly assigned to two groups. The control group was slowly injected with tramadol 1.5 mg/kg using a Murphy dropper, whereas the experimental group was intravenously injected with butorphanol 0.02 mg/kg. Severity, pain score, and sedation score of CRBD were evaluated at 0 min, 5 min, 15 min, 30 min, 1 h, and 6 h later. Results The severity score of CRBD and visual analog scale pain score were lower in the butorphanol group than in the control group, whereas the sedation score was higher in the butorphanol group than in the control group. Conclusion Butorphanol relieves on postoperative urination discomfort and pain compared with tramadol.
Highlights
Urethral catheterization is widely adopted during surgeries because it can effectively reduce complications caused by urine retention [1]
Catheter-related bladder discomfort (CRBD) is defined as an uncomfortable feeling in the suprapubic area along with urgent and frequent urination, with or without incontinence [1, 2]. e rate of catheter-related bladder discomfort (CRBD) can be as high as 47%–90% [2], whereas it is 38%–57% in the postanesthesia care unit (PACU) [3, 4]
66 men with spontaneous CRBD in the PACU were selected, based on the American Society of Anesthesiologists (ASA) physical status ≤2 and CRBD score >2, with 16-French Foley catheters adopted after surgery
Summary
Urethral catheterization is widely adopted during surgeries because it can effectively reduce complications caused by urine retention [1]. Clinical studies have shown that moderate-to-severe CRBD occurs predominantly in male patients [7], which results in an increased incidence of postoperative agitation [2], extended hospital stay, poor satisfaction, and inevitable financial issues. Some studies have shown that solifenacin, butylscopolamine, oxybutynin, paracetamol, and tolterodine can improve CRBD symptoms [9,10,11,12]. These drugs have no satisfactory clinical effects. Is study aimed to assess the curative effect of butorphanol as a K receptor agonist in the treatment of postoperative CRBD.
