Introduction: Catheter-related bladder discomfort (CRBD) after perioperative catheterisation of the urinary bladder (COUB) is not uncommon.
Aim of the study: We evaluated the efficacy of both oral gabapentin and trospium in preventing CRBD during the early postoperative period in patients admitted to the surgical intensive care unit (S-ICU).
Material and Methods: 120 patients aged 20–65 years, ASA I, II or III who were admitted to S-ICU after undergoing elective spinal surgery (ESS) with COUB were included. They were randomly assigned to be administered either an oral 400 mg gabapentin capsule (Group G) or an oral 60 mg slow-release trospium chloride capsule (Group T) or nothing (Group C). The primary goal was the occurrence of CRBD and its severity at 1, 2, 6, 12, and 24 hours after the study drug administration (SDA).
Results: Group G and group T had a statistically significant lower incidence of CRBD than group C at 1, 2, 6, 12, and 24 hours after SDA, respectively. Both had considerably lower severity than group C in the first two hours only (P= 0.001 and 0.001, respectively). Group T had non-significantly lower incidence and severity of CRBD than group G. Group G had significantly lower mean total fentanyl requirements for up to 24 hours after SDA than group T and group C (P < 0.001).
Conclusion: Both oral gabapentin capsules and slow release trospium chloride capsules administered postoperatively, significantly decreased both the incidence of CRBD and its severity in the early postoperative period amongst S-ICU patients, without significant differences between the two drugs.
