Intraoperative Administration of Diphenhydramine Attenuates Postoperative Catheter Related Bladder Discomfort in Patient Following Percutaneous Nephrolithotomy

Background: We intend to evaluate the effect of intraoperative diphenhydramine administration on incidence and severity of catheter related bladder discomfort (CRBD) and pain after percutaneous nephrolithotomy. Methods: In a double blind randomized clinical trial, adult male patients undergoing percutaneous nephrolithotomy were enrolled. They were randomized into two groups by a computerized digital random allocation method. Before anesthesia induction, group D (Diphenhydramine group) (n = 48) received 5 ml normal saline containing 0.5 mg/kg of diphenhydramine intravenously. In group C (Control group) (n = 48), 5 ml of normal saline was injected in the same manner. Induction and maintenance of anesthesia were identical in both groups. The incidence and severity of CRBD and postoperative pain were assessed at recovery room. Results: The incidence of CRBD was significantly lower in group D than in group C (14% vs. 63%, P=0.001). The severity of CRBD was milder in group D in comparison to group C (P<0.05). Postoperative pain score was significantly lower in group D (P<0.05). Conclusion: Intraoperative administration of diphenhydramine is an effective practice for the prevention of CRBD after percutaneous nephrolithotomy in male patients and can reduce postoperative pain as well.

Effect of magnesium sulfate perioperative infusion on postoperative catheter-related bladder discomfort in male patients undergoing laparoscopic radical resection of gastrointestinal cancer: a prospective, randomized and controlled study

BackgroundLaparoscopic radical resection of gastrointestinal cancer is associated with a high incidence of postoperative catheter-related bladder discomfort (CRBD). Studies on the benefits of magnesium sulfate intravenous infusion during the perioperative period post-laparoscopic surgery are yet lacking.MethodsA total of 88 gastrointestinal cancer male patients scheduled for laparoscopic radical resection were randomly divided into two groups: normal saline (control) and magnesium. In the magnesium group, a 40 mg/kg loading dose of intravenous magnesium sulfate was administered for 10 min just after the induction of anesthesia, followed by continuous intravenous infusion of 15 mg/kg/h magnesium sulfate until the end of the surgery; the control group was administered the same dose of normal saline. Subsequently, 2 μg/kg sufentanil was continuously infused intravenously by a postoperative patient-controlled intravenous analgesia (PCIA) device. The primary outcome was the incidence of CRBD at 0 h after the surgery. The secondary outcomes included incidence of CRBD at 1, 2, and 6 h postsurgery, the severity of CRBD at 0, 1, 2, and 6 h postsurgery. Remifentanil requirement during surgery, sufentanil requirement within 24 h postsurgery, the postoperative numerical rating scale (NRS) score at 48 h after the surgery, magnesium-related side effects and rescue medication (morphine) requirement were also assessed.ResultsThe incidence of CRBD at 0, 1, 2, and 6 h postoperatively was lower in the magnesium group than the control group (0 h: P = 0.01; 1 h: P = 0.003; 2 h: P = 0.001; 6 h: P = 0.006). The incidence of moderate to severe CRBD was higher in the control group at postoperative 0 and 1 h (0 h: P = 0.002; 1 h: P = 0.028), remifentanil requirement during surgery were significantly lower in the magnesium group than the control group. Sufentanil requirements during the 24 h postoperative period were significantly lower in the magnesium group than the control group. The NRS score was reduced in the magnesium group compared to the control group in the early postoperative period. Magnesium-related side effects and rescue medication (morphine) did not differ significantly between the two groups.ConclusionsIntravenous magnesium sulfate administration reduces the incidence and severity of CRBD and remifentanil requirement in male patients undergoing radical resection of gastrointestinal cancer. Also, no significant side effects were observed.Trial registrationChictr.org.cn ChiCTR2100053073. The study was registered on 10/11/2021.

Vitamin C and catheter-related bladder discomfort after transurethral resection of bladder tumor: A double-blind, randomized, placebo-controlled study

Study objectiveWe evaluated the effect of vitamin C administration on postoperative catheter-related bladder discomfort (CRBD). DesignA double-blind, randomized controlled trial. SettingUniversity tertiary hospital. PatientsThe participants were patients undergoing transurethral resection of bladder tumor. InterventionPatients were randomly assigned to either vitamin C (n = 59) or control (n = 59). The vitamin C group received 1 g of vitamin C intravenously and the control group received normal saline, administered after the induction of anesthesia. MeasurementsThe primary endpoint was moderate or greater CRBD immediately postoperatively. Secondary outcomes included the incidence of moderate or greater CRBD at 1, 2, and 6 h postoperatively. The symptom of CRBD is either a burning sensation with an urge to void or discomfort in the suprapubic area. Moderate CRBD was defined as spontaneously reported by the patient without any behavioral responses, such as attempts to remove the urinary catheter, intense verbal reactions, and flailing limbs. Severe CRBD was spontaneously reported by the patient with behavioral responses. Patient satisfaction scores were also evaluated. Main resultsThe group that received vitamin C exhibited a significantly lower incidence of moderate or greater CRBD immediately postoperatively compared with the control group (17 [28.8%] vs. 40 [67.8%], p < 0.001, relative risk [95% confidence interval] = 0.426 [0.274–0.656]). The vitamin C group also showed a significantly lower incidence of moderate or greater CRBD at 1 and 2 h postoperatively compared with the control group (10 [16.9%] vs. 25 [42.4%], p = 0.003; and 5 [8.5%] vs. 16 [27.1%], p = 0.008, respectively). However, there was no significant difference in the incidence of moderate or greater CRBD 6 h postoperatively. Patient satisfaction scores were significantly higher in the vitamin C group than in the control group (5.0 ± 1.3 vs. 4.4 ± 1.4, p = 0.009). ConclusionsPatients who received vitamin C had decreased CRBD and improved patient satisfaction following transurethral resection of bladder tumor.

Duloxetine in Reducing Catheter-Related Bladder Discomfort: A Prospective, Randomized, Double-Blind, Placebo-Controlled Study.

The excessive desire to void with discomfort in the supra-pubic region, which is experienced postoperatively by patients who underwent urinary catheterization, is known as catheter-related bladder discomfort. In this study, we evaluated duloxetine, a selective serotonin and norepinephrine reuptake inhibitor, in preventing catheter-related bladder discomfort. Around 64 adults (18-60 years), of either sex, with American Society of American Society of Anesthesiologists (ASA) physical status I and II, scheduled to undergo elective gastrointestinal carcinoma surgeries under general anesthesia were analyzed in the final assessment of 2 comparative groups C and D of 32 patients each. Group D received 1 ranitidine tablet of 150 mg and 1 duloxetine tablet of 60 mg, while group C patients received 2 tablets of ranitidine of 75 mg 2 hours prior to induction. A 16 F Foley catheter was used to catheterize bladder intra-operatively, and 10 mL of distilled water was used to fill the balloon. At 0, 1, 2, and 6 hours, the catheter-related bladder discomfort was evaluated, and categorized into none, mild, moderate, and severe. The study drug's adverse effects, if any, were reported. At all-time intervals, group D had lower incidence and severity of catheterrelated bladder discomfort than group C (P < .05). Compared to group C, patients in group D had a higher incidence of nausea, dizziness, and vomiting; nevertheless, the difference was statistically insignificant (P > .05). Duloxetine of 60 mg given orally 2 hours before induction decreases the incidence and severity of catheter-related bladder discomfort.

The efficacy of peripheral nerve block on postoperative catheter-related bladder discomfort in males: A systematic review and meta-analysis.

To determine the efficacy of peripheral nerve block (PNB) in preventing postoperative catheter-related bladder discomfort (CRBD). Up to July 1, 2022, the PubMed, Embase and Cochrane Central Register of Controlled Trials databases were searched, and all articles that met the PICOS (Patient, Intervention, Comparator, Outcome, Study design) criteria were enrolled. The included trials were evaluated using the Cochrane Collaboration's tool. Patients in the block group received bilateral PNB, while those in the non-block group did not need any additional procedure or simply achieved "sham block". CRBD was quantified using the visual analog scale (VAS) score, which was questioned and recorded at 0-1 h, 1-2 h, 4-8 h, 8-12 h and 12-24 h intervals. The incidences of CRBD, moderate to severe CRBD and postoperative nausea and vomiting (PONV) were meta-analysed. Six trials with a total of 544 patients were considered. First, the block group had a lower incidence of CRBD than the non-block group at 0-1 h (OR 0.22; 95% CI, 0.18-0.08; P < 0.0001), 1-2 h (OR 0.14; 95% CI, 0.08-0.26; P < 0.00001), 4-8 h (OR 0.27; 95% CI, 0.13 to 0.58; P < 0.0008) and 8-12 h (OR 0.51; 95% CI, 0.30 to 0.87; P = 0.01). Second, the block group showed a lower incidence of moderate to severe CRBD than the non-block group at 0-1 h, 1-2 h and 4-8 h, and the ORs were 0.12 (95% CI, 0.03 to 0.49; P = 0.003), 0.17 (95% CI, 0.08 to 0.37; P < 0.00001) and 0.29 (95% CI, 0.15 to 0.55; P = 0.0002),respectively. Finally, the block group was significantly associated with a decreased incidence of PONV (OR, 0.14; 95% CI, 0.05 to 0.39; P = 0.0002). This meta-analysis suggested that PNB markedly reduced the incidence and severity of early postoperative CRBD and decreased the occurrence of PONV.

Single-dose intravenous nefopam on postoperative catheter-related bladder discomfort in patients undergoing transurethral resection of prostate: a randomized, double-blind placebo-controlled trial.

Transurethral resection of prostate (TURP) with postoperative catheter traction can lead to significant catheter-related bladder discomfort (CRBD). This condition causes many postoperative complications and low patient satisfaction.This study aimed to evaluate the effectiveness ofpreoperative single-dose intravenous nefopam on the incidence and severity of CRBD and its adverse effects. This randomized, controlled, double-blind study included patients who underwent TURP under spinal anesthesia with postoperative urinary catheter traction. Patients were allocated into nefopam (NF) and normal saline (NS) groups. Twenty mg of nefopam in normal saline solution (NSS) 100mL or NSS 100mL were given intravenously before TURP. The primary outcome was the incidence of CRBD. Seventy-three patients were randomized into NF (n = 37) and NS (n = 36) groups. There were 35 and 33 patients in the NF and NS groups, respectively, in the final analysis. The incidences of CRBD were 45.71% and 84.85% in the NF and NS groups at 6h after operation, respectively, OR 0.54 (95% CI 0.36, 0.73), while before the end of catheter traction, the corresponding incidences were 37.14% and 75.76%, respectively, OR 0.49 (95% CI 0.28, 0.84). The CRBD scores were statistically significantly lower in the NF group at both time points. Morphine consumptions and adverse effects were not different between groups. Patient satisfaction was higher in the NF group. Single-dose nefopam significantly reduced the incidence and severity of CRBD in patients undergoing TURP with urinary catheter traction at 6h after the procedure and before the end of catheter traction without increasing the adverse effects.

Safety and efficacy of wrist-ankle acupuncture in treating catheter-related bladder discomfort after transurethral resection of the prostate: a double-blind randomized clinical trial.

BackgroundBenign prostatic hyperplasia (BPH) is an age-related condition and its prevalence has increased as China’s population ages. Transurethral resection of the prostate (TURP) remains the gold standard for treating moderate to severe BPH. Routine placement of a urinary catheter after TURP is often associated with catheter-related bladder discomfort (CRBD). The development of CRBD is related to an increased synthesis of prostaglandin (PG), and wrist-ankle acupuncture (WAA) can inhibit the expression of PG at the site of inflammation, thus alleviating CRBD symptoms. Here we evaluated the efficacy of WAA in alleviating CRBD in patients undergoing TURP.MethodsA total of 46 patients who underwent elective TURP in Hebei Provincial Hospital of Traditional Chinese Medicine from June 2022 to July 2022 were randomly divided into two groups according to the complete randomization method. The WAA group (n=23) and the control group (n=23). The WAA group received WAA, and the needles were retained for 24 h. The control group was treated with sham needles that did not penetrate the skin, and the needles were also retained for 24 h. At T1 (0 h after entering the ward), T2 (0.5 h after entering the ward), T3 (6 h after entering the ward), and T4 (24 h after entering the ward), CRBD severity score, visual analogue scale (VAS) and vital signs monitor were used for assessment. Accidents were recorded in the case report form. Graded data using Wlicoxon signed rank sum test, repeated measures using repeated measures analysis of variance.ResultsA total of 46 patients participated in this study, and 44 patients completed the experiment. At T2, T3, and T4, the severity of CRBD in the WAA group was significantly lower than that in the control group (all P<0.05), and the VAS pain score was significantly lower in the WAA group than in the control group (all P<0.05). In contrast, the vital signs, including mean arterial pressure (MAP), heart rate (HR), and blood oxygen saturation, showed no statistical significance (all P>0.05). No accident occurred in both groups.ConclusionsWAA can effectively relieve CRBD symptoms after TURP. WAA deserves further research and assessment for clinical practice.Trial RegistrationChinese Clinical Trial Registry identifier: ChiCTR2200061525..

Preventing Catheter Related Bladder Discomfort (CRBD) in male patients undergoing Lower Urinary tract surgery with Bilateral Pudendal Nerve Block:A Randomized Controlled Trial

Objective: To compare the frequency and severity of post-operative CRBD in patients undergoing TURP and TURBT with spinal anaesthesia with pudendal nerve block against spinal anaesthesia alone.&#x0D; Study Design: A randomized controlled trial (Clinical trials.gov: NCT05022160)&#x0D; Place and Duration of Study: Armed Forces Institute of Urology (AFIU), Rawalpindi Pakistan, from Aug to Nov, 2021.&#x0D; Methodology: The trial comprised 250 patients scheduled to have a transurethral resection of the prostate (TURP) or a transurethral resection of a bladder tumour (TURBT) under spinal anaesthesia. They were split into two groups: study (group-P) and control (group-C). After surgery, the patients in the study-group were given a bilateral pudendal nerve block. At 3, 8, 12, and 24 hours following surgery, the frequency and severity of catheter-related bladder discomfort (CRBD) were documented.&#x0D; Results: CRBD frequencies were significantly lower in pudendal group at 3 hours 42 (33.8%) vs 72 (58.5%), p &lt;0.001), 8 hours 81 (65.3%) vs 111 (90.2%), p&lt;0.001 and 12 hours 53 (42.7%) vs 73 (59.3%), p=0.009 after the surgery. The postoperative pain score in pudendal group was lower at 3 hours (p&lt;0.001), 8 hours (p &lt;0.001), and 12 hours (p=0.02) but there was no statistically significant difference between the two groups at 24 hours (p=0.06).&#x0D; Conclusion: When used in conjunction with spinal anaesthesia, a pudendal nerve block reduces the frequency and severity of catheter-related bladder discomfort for up to 12 hours after surgery.

Comparison of the Effect of Sugammadex and Pyridostigmine on Postoperative Catheter-Related Bladder Discomfort: A Retrospective Matched Cohort Analysis.

Background and Objectives: As the use of sugammadex for reversing neuromuscular blockade during general anesthesia increases, additional effects of sugammadex have been reported compared to cholinesterase inhibitors. Here, we compare the incidence of postoperative catheter-related bladder discomfort (CRBD) between sugammadex and pyridostigmine/glycopyrrolate treatments for reversing neuromuscular blockade. Materials and Methods: We retrospectively analyzed patients aged ≥ 18 years who underwent surgery under general anesthesia, received sugammadex or pyridostigmine with glycopyrrolate to reverse neuromuscular blockade, and had a urinary catheter in the post-anesthesia care unit between March 2019 and February 2021. After applying the exclusion criteria, 1179 patients were included in the final analysis. The incidence and severity of CRBD were collected from post-anesthesia recovery records. Results: The incidence was 13.7% in the sugammadex group (n = 211) and 24.7% in the pyridostigmine group (n = 968). Following propensity score matching, 211 patients each were included in the pyridostigmine and sugammadex matched group (absolute standardized difference (ASD), 0.01–0.05). Compared to the pyridostigmine group, the odds ratio for CRBD occurring in the sugammadex group was 0.568 (95% confidential interval, 0.316–1.021, p = 0.059). Conclusions: Sugammadex has a similar effect on the occurrence of postoperative CRBD compared with pyridostigmine.

Different interventions for preventing postoperative catheter-related bladder discomfort: a systematic review and meta-analysis.

Catheter-related bladder discomfort (CRBD) is a common complication of intraoperative urinary catheterization. Various studies have evaluated the efficacy of different interventions in postoperative CRBD. The present review was performed to assess the efficacy of these interventions. PubMed, Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) databases were systematically searched to identify randomized controlled trials (RCTs) investigating the efficacy of different drugs for the prevention of postoperative CRBD. This review evaluated the incidence and severity of CRBD after different interventions at 0, 1, 2, and 6h postoperatively. Forty-five studies including 31 different drugs were analyzed. Eleven drugs were investigated in more than two RCTs, of which dexmedetomidine, gabapentin, tolterodine, tramadol, ketamine, nefopam, oxybutynin, pregabalin, and pudendal nerve block (PNB) generally showed significantly higher efficacy than controls postoperatively. Solifenacin only showed significant efficacy compared with the control at 0h, and intravenous lidocaine only showed significant efficacy compared with the control at 6h. There were insufficient trials to draw conclusions regarding atropine, butylscopolamine, chlorpheniramine, clonidine, darifenacin, diphenhydramine, glycopyrrolate, intravesical bupivacaine, ketamine-haloperidol, pethidine-haloperidol, ketorolac, lidocaine-prilocaine cream, magnesium, hyoscine n-butyl bromide, oxycodone, paracetamol, parecoxib, trospium, resiniferatoxin, or amikacin. However, all but pethidine-haloperidol and chlorpheniramine showed some efficacy at various time points compared with controls. This review suggests that dexmedetomidine, gabapentin, tolterodine, tramadol, ketamine, nefopam, oxybutynin, pregabalin, and PNB are effective in preventing postoperative CRBD. Considering the efficacy and adverse effects of all drugs, dexmedetomidine and gabapentin were ranked best.

The efficacy of dexmedetomidine for the prevention of catheter-related bladder discomfort: A systematic review and meta-analysis.

Background:The effective therapy to reduce postoperative catheter-related bladder discomfort (CRBD) remained unknown.Objective:We attempted to manage the systematic review and a meta-analysis to clarify the efficacy of dexmedetomidine (DEX) in potential prevention on CRBD.Methods:We performed the meta-analysis on randomized clinical trials (RCTs), and searched the databases from Web of Sciences, Embase and referred Cochrane Library published from October 2016 to September 2020. Data extraction was carefully conducted by 2 authors, respectively. Meta-analysis that was applied synthetically concerns the incidence and severity of CRBD and the treatment effect of DEX on CRBD.Results:We acquired 5 RCTs with interventions of DEX on CRBD. Meta-analysis showed DEX has significantly reduced the incidence and severity of CRBD compared with control at 0 hour (risk ratios [RR] = 0.40, 95% CI = 0.53–0.29, P < .01), 1 hour (RR = 0.44, 95% CI = 0.34–0.57, P < .01), and 2 hours (RR = 0.43, 95% CI = 0.32–0.58, P < .01) and 6 hours (RR = 0.43, 95% CI = 0.29–0.63, P < .01). DEX was also associated with lower incidence of moderate to severe CRBD at 0, 1, and 6 hours after surgery. There were no significant differences in adverse events other than bradycardia, hypotension, and hypertension.Conclusion:The 5 RCTs showed great effectiveness in reducing the incidence and severity of the early and later postoperative CRBD. Meta-analysis showed that DEX interventions were useful in preventing the early and later postoperative CRBD without significant side effects.

Effects of dexamethasone on catheter-related bladder discomfort and emergence agitation: a prospective, randomized, controlled trial.

BackgroundCatheter-related bladder discomfort (CRBD) is common in patients with a urinary catheter and is a risk factor for emergence agitation (EA). The mainstay of CRBD management is anticholinergics. Dexamethasone inhibits acetylcholine release. This study aimed to evaluate the effects of dexamethasone on postoperative CRBD and EA.MethodsIn this prospective study, 90 patients undergoing urological surgery requiring urinary catheterization were allocated randomly to one of two groups (each n = 45). Before induction of anesthesia, the dexamethasone group received 10 mg (2 ml) of dexamethasone intravenously, while the control group received 2 ml of saline in the same manner. The incidence and severity of CRBD were assessed 0, 1, 2, and 6 h after the patient arrived in the post-anesthesia care unit (PACU) as the primary outcomes. The incidence and severity of EA were also compared during emergence and recovery from anesthesia as secondary outcomes.ResultsThe incidences of CRBD in the control group and dexamethasone group at 0, 1, 2, and 6 h postoperatively were 28.9% and 15.6%, 55.6% and 55.6%, 57.8% and 46.7%, and 53.3% and 51.1%, respectively. The incidence and severity of CRBD assessed at 0, 1, 2, and 6 h postoperatively did not show intergroup differences. The incidence and severity of EA in the operating room and PACU also showed no difference between the groups.ConclusionsDexamethasone (10 mg) administered before induction of anesthesia did not further reduce the incidence or severity of CRBD or EA in patients undergoing urological surgery.

Occurrence and Severity of Catheter-Related Bladder Discomfort of General Anesthesia Plus Epidural Anesthesia vs. General Anesthesia in Abdominal Operation With Urinary Catheterization: A Randomized, Controlled Study.

Background: This randomized, controlled study aimed to investigate the effect of general anesthesia plus epidural anesthesia on catheter-related bladder discomfort (CRBD) in patients who underwent abdominal operation with urinary catheterization.Methods: A total of 150 patients scheduled for abdominal operation under anesthesia with urinary catheterization were randomized to receive general anesthesia plus epidural anesthesia (N = 74, GA + EA group) or general anesthesia (N = 76, GA group). The occurrence and severity of CRBD, systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were recorded at 0 hour (h), 0.5, 1, and 3 h after tracheal extubation. Besides, postoperative adverse events were assessed.Results: The occurrence and severity of CRBD at 0, 0.5, 1, and 3 h were all reduced in GA + EA group compared to GA group (all P < 0.05). Meanwhile, subgroup analyses showed that the reduction of occurrence and severity of CRBD in GA + EA group compared to GA group was more obvious in male patients and patients ≥50 years. Besides, SBP at 0, 0.5, 1, and 3 h, as well as DBP at 0, 0.5, and 3 h were all decreased in GA + EA group compared to GA group (all P < 0.05), while HR was increased at 0 h in GA + EA group compared to GA group (P = 0.034). Moreover, the occurrence of pain, severity of pain and occurrence of vomiting were similar between GA + EA group and GA group (all P > 0.05).Conclusion: General anesthesia plus epidural anesthesia decreases CRBD occurrence and severity with tolerable safety compared with general anesthesia in patients who undergo abdominal operation with urinary catheterization.

Effect of chlorpheniramine administration on postoperative catheter-related bladder discomfort in patients undergoing transurethral excision of bladder tumor: a prospective randomized study

Catheter-related bladder discomfort (CRBD) is postoperative distress caused by a urinary catheter. CRBD is related to muscarinic receptor activation. Chlorpheniramine has antimuscarinic properties. Hence, this investigation was undertaken to evaluate the efficacy of chlorpheniramine in preventing CRBD in patients undergoing transurethral resection of bladder tumor (TURBT). Seventy-six patients scheduled for TURBT under general anesthesia were assigned into two groups. In the chlorpheniramine group (n = 38), 100ml normal saline containing 0.1mg/kg chlorpheniramine was infused after general anesthesia induction. In the control group (n = 38), 100ml normal saline alone was infused. The incidence and severity of CRBD were assessed at 1, 6, and 24h postoperatively. The 1-h postoperative incidence of CRBD was lower in the chlorpheniramine group based on the unadjusted analysis [16 (42%) vs. 28 (74%), risk difference 32%, 95% confidence interval 8-51, p = 0.005]. After adjusting the size of the urinary catheter, post hoc analysis showed that the 1-h postoperative incidence of CRBD was lower in the chlorpheniramine group (p = 0.004). The CRBD severity score was lower in the chlorpheniramine group at 1 and 6h after operation based on the unadjusted analysis (p = 0.012 and p = 0.007, respectively). After adjusting the urinary catheter size, post hoc analysis showed that 1- and 6-h CRBD severity score was lower in the chlorpheniramine group (p = 0.012 and p = 0.008, respectively). The incidence of rescue medication was lower in the chlorpheniramine group [10 (26%) vs. 20 (53%), risk difference 26%, 95% confidence interval 3-47, p = 0.019]. The overall incidence of complications such as nausea, vomiting, dry mouth, flushing, dizziness, and blurred vision was comparable between the two groups. Chlorpheniramine administration significantly reduces the incidence and severity of CRBD in the patients undergoing TURBT. KCT0004880 ( https://cris.nih.go.kr/ ).

The Effect of Transcutaneous Electrical Acupoint Stimulation on Postoperative Catheter-Related Bladder Discomfort in Patients Undergoing Transurethral Resection of the Prostate.

Background Catheter-related bladder discomfort (CRBD), an extremely distressing complication secondary to an indwelling urinary catheterization, is frequently reported in patients with transurethral resection of the prostate (TURP), postoperatively. A prospective, randomized, controlled, double-blind study was designed to assess the efficacy of transcutaneous electrical acupoint stimulation (TEAS) as a treatment for CRBD in patients undergoing TURP. Methods Seventy benign prostatic hyperplasia male patients undergoing TURP under general anesthesia requiring intraoperative urinary catheterization were enrolled for the trial. An experienced acupuncturist performed TEAS for 30 minutes before general anesthesia with acupoints RN7, RN6, RN5, RN4, and RN3 and bilateral BL32, BL33, and BL34. Mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SPO2), body temperature (T), and blood samples were collected during the surgery. A series of assessments included the incidence and severity of CRBD, postoperative pain, nausea and vomiting, and physical and mental state measurements. Results The incidence of CRBD was significantly lower in TEAS group than in control group at the time T5 [9(26%) vs. 28(80%), P < 0.001], T9 [20(57%) vs. 28(80%), P=0.039], T11 [7(20%) vs. 31(89%), P < 0.001], and T12 [4(11%) vs. 7(20%), P=0.003]. The severity of CRBD was significantly lower in TEAS group than in control group at the time T5 [0 vs. 10 (29%), P < 0.001], T9 [2(6%) vs. 10(29%), P=0.011], and T11 [0 vs .9(26%), P=0.002]. The QoR-40 total score was higher in TEAS group at time T11 [191.7(4.4) vs. 189.1(4.3), P=0.007] and T12 [195.3(1.9) vs. 193.3(3.0), P < 0.001]. The postoperative analgesia requirement was higher in control group [5.0(2.9) vs. 3.8(1.9), P=0.045]. Conclusions TEAS could significantly prevent the incidence and severity of CRBD, reduce the postoperative analgesic requirement in the early postoperative period, and promote the quality of early recovery in patients undergoing TURP.

A randomised‐controlled, prospective study on the effect of dorsal penile nerve block after TURP on catheter‐related bladder discomfort and pain

In the present study, the impact of penile nerve block (PNB) on postoperative pain and Catheter-Related Bladder Discomfort (CRBD) in the transurethral resection of prostate(TURP) patients were evaluated. Participants of the present study were selected from patients who performed TURP under spinal anaesthesia for benign prostatic hyperplasia (BPH) between January 2018 and July 2020. The present study was planned as a single-centre, randomised-controlled prospective study in which the patients were divided into two groups. Group 1 was administered Control (n:40), and Group 2 ultrasonography(USG) guided PNB (n:40). The patients were included in the Groups, respectively. Visual analogue scale (VAS) scores were questioned and recorded in order to evaluate the postoperative pain complaints of the patients after the operation. In addition, in order to evaluate the CRBD, VAS scores were questioned and recorded as 0th, 0-1th hour, 1st-2nd hour, 2nd-4th hour, 4th-8th hour, 8th-12th hour, and 12th-24th hour. In addition, postoperative pain and need for analgesic drug were recorded. Tramadol was given to patients with moderate to severe CRBD. The findings were compared between the Groups. There was no statistical difference demographic and per-operative data between Group 1 and Group 2. The CRBD and pain-related VAS scores were significantly higher in Group 1 between the 0 and 8th hours. There was no difference between VAS scores in the postoperative 8-24th hours. In total 24hours, Group 2's need for tramadol was significantly less than Group 1. On examining the factors affecting CRBD in the multivariate analysis, age, body mass index(BMI), prostate volume, operation time do not affect CRBD statistically, and only PNB reduces CRBD (P: .029). While less drug-related complications were observed in Group 2, no serious complications related to PNB were observed. Penile nerve block is an effective method for the decrease pain and CRBD after urological surgery. It will also reduce the need for analgesics, and provide painless patients in the postoperative period.

Effects of Chlorpheniramine Maleate on Catheter-Related Bladder Discomfort in Patients Undergoing Ureteroscopic Stone Removal: A Randomized Double-Blind Study.

Catheter-related bladder discomfort (CRBD) associated with intraoperative urinary catheterization is a distressing symptom during recovery from anesthesia. Anticholinergics have been used to manage CRBD. Chlorpheniramine maleate (CPM) is a first-generation antihistamine, which also has anticholinergic effects. This study was undertaken to evaluate the efficacy of CPM in preventing CRBD. Seventy-six adults (19-65 years old) with American Society of Anesthesiologists physical status I, II, or III of either sex, undergoing elective ureteroscopic stone removal under general anesthesia were randomized into one of two groups (each n = 38). Group C (control) received a placebo, and group CPM received 8 mg of intravenous CPM before the induction of anesthesia. CRBD was assessed upon arrival in the post-anesthetic care unit at 0, 1, 2, and 6 h. The severity of CRBD was graded as none, mild, moderate, and severe. Tramadol was administered when the severity of CRBD was more than moderate. The incidence rate and overall severity of CRBD did not differ between the groups at any of the time points (р > 0.05). The incidence of moderate CRBD was higher in group C than in group CPM only at 0 h (26.3% vs. 5.3%, р = 0.025). However, fewer patients in the CPM group required rescue tramadol to relieve CRBD after surgery (31.6% vs. 60.5%, р = 0.011). CPM administration before the induction of anesthesia had little effect on the incidence and severity of CRBD after surgery, but it reduced the administration of tramadol required to control CRBD postoperatively.

The Effect of Intravesical Diluted Bupivacaine on Catheter-Related Bladder Discomfort in Young and Middle-Aged Male Patients During Postanaesthetic Recovery.

ObjectiveCatheter-related bladder discomfort (CRBD) that manifests as agitation and bladder hyperactivity is a common problem in young male patients. Local anaesthetics are typically recommended for this problem. Hence, this study was conducted to determine the effect of intravesical diluted bupivacaine on CRBD in young male patients during postanaesthetic recovery.MethodsThis double-blinded randomised clinical trial included 68 consecutive patients, aged 20–60 years, who underwent urinary catheterisation during surgery and anaesthesia at a university hospital during 2017–2018. Patients were randomly assigned to receive either 50 ml of intravesical diluted (0.2%) bupivacaine (n=37) or normal saline (n=31). The incidence and severity of CRBD were then evaluated in PACU and compared between the two groups.ResultsIn this study, 16.2% of patients in the bupivacaine group and 83.9% in the saline group had discomfort at arrival in the recovery room, exhibiting a significant intergroup difference (p=0.0001). Moreover, after 15–20 min, the incidence of CRBD was 16.2% and 90.3% in the bupivacaine and normal saline groups, respectively, which again demonstrated a significant statistical difference (p=0.0001). In addition, the severity of CRBD was lower in the bupivacaine group, during both periods (p=0.005). The saline group reported significantly higher use of pethidine and midazolam (p=0.005).ConclusionIt may be concluded that intravesical diluted bupivacaine can significantly decrease the incidence and severity of CRBD in young male patients during recovery from anaesthesia. Therefore, the use of this method is highly recommended.

Efficacy of a novel urinary catheter for men with a local anesthetic injection port for catheter-related bladder discomfort: a randomized controlled study.

The NMOC-3WAY catheter® is a novel urinary catheter for men that can be used to inject a local anesthetic into the urethra. We sought to assess whether the injection of a local anesthetic into the urethra via the NMOC-3WAY catheter® would reduce catheter-related bladder discomfort (CRBD) after endovascular aneurysm repair (EVAR). Adult male patients who underwent elective EVAR for abdominal aortic aneurysms were randomly assigned to the 2% lidocaine group and the normal saline group (control group). CRBD was evaluated at 0, 1, 2, 4, and 6h after surgery. The primary outcome was the incidence of CRBD at 0h after surgery. Data for 37 patients (19 in the lidocaine group and 18 in the control group) were analyzed. CRBD was observed at 0h in six patients (31.6%; mild, n = 5; moderate, n = 1) in the lidocaine group and in five patients (27.8%; mild, n = 1; moderate, n = 3; severe, n = 1) in the control group. The control group showed a tendency to have severe CRBD at 0h, although there was no significant difference in either the incidence (P = 0.80) or severity (P = 0.21) of CRBD between the two groups. Our results suggest that the use of the NMOC-3WAY catheter® for the injection of 2% lidocaine into the urethra does not reduce the incidence of CRBD immediately after EVAR. However, it may reduce moderate or severe CRBD that may lead to postoperative distress and agitation.

Pooled analysis of the efficacy and safety of intraoperative dexmedetomidine on postoperative catheter-related bladder discomfort.

The goal of the pooled analysis was to demonstrate the efficacy and safety of intraoperative dexmedetomidine in postoperative catheter-related bladder discomfort (CRBD). MEDLINE, the Cochrane Central Register of Controlled Trials, and the Excerpta Medica Database (Embase) were used to pick out randomized controlled trials (RCTs) that used intraoperative dexmedetomidine in postoperative CRBD. This study was carried out using the preferred reporting items for systematic reviews and pooled analysis. We used RevMan version 5.3.0. to analyze the data. Seven RCTs involving 607 patients were brought into in the analysis. The incidence of CRBD and the incidence of moderate to severe CRBD were assessed at 0 hours, 0.5 or 1 hour, 2 or 3 hours, 6 hours, and 12 or 24 hours postoperatively. The analysis proved that both the incidence of CRBD (P < .00001) and the incidence of moderate to severe CRBD had a statistically significant reduction at 0 hours, 0.5 or 1 hours, 2 or 3 hours, and 6 hours postoperatively (P < .00001, P <.00001, P <.00001, P = .003, respectively). The postoperative pain score was lower in the dexmedetomidine group at 0 hours (P < .00001) and 1 hour (P = .002). Safety assessments indicated that there were no statistical differences between dexmedetomidine and control for side effects, mainly including dry mouth (P = .99) and postoperative vomiting and nausea (P = .77). The pooled analysis demonstrates that intraoperative dexmedetomidine administration decreases the rate and severity of early postoperative CRBD without causing significant side effects.
