Comparison of pain and proper sample status according to usage of tenaculum and analgesia: a randomized clinical trial.

ABSTRACT: OBJECTIVE:Colposcopic biopsy is a discomfortable procedure. Additionally, it creates negative influence on sexuality. This study aimed to investigate the relationships among tenaculum, pain perception, and biopsy size during colposcopy. METHODS:In total, 228 patients who underwent colposcopy-directed biopsy were included, and randomized into 4 groups based on whether analgesic and tenaculum were used and replaced (tenaculum with n=58/without analgesic n=56, no tenaculum replacement with n=57/without analgesic n=57). Lidocaine hydrochloride (40 mg) plus adrenaline (0.025 mg) was administered in the analgesic groups. The pain was assessed using a linear visual analog scale. The biopsy specimen size was measured in millimeters. RESULTS:The mean age of the patients was 42.85±8.88 years. The most frequent colposcopy indications were atypical squamous cells of undetermined significance and human papilloma virus-positive results on cervical cytology (30.2%; n=69). Low- and high-grade intraepithelial lesions were noted in 14.91% (n=34) and 10.96% (n=25) women through colposcopy-directed biopsy results, respectively. Tenaculum replacement increased pain perception in the without analgesic group; however, no statistically significant differences were noted between of the groups with and without tenaculum replacement with analgesic. The size and number of biopsy specimens were not associated with tenaculum replacement and analgesic use. CONCLUSION:Administration of analgesics decreased discomfort and pain in patients. Tenaculum replacement aided colposcopists in manipulating the cervix. Additionally, administration of analgesics relieved pain in the tenaculum replacement group.

Project description:Postoperative pain after major open gynecologic surgeries requires appropriate pain management.This study aimed at comparing perioperative patient controlled epidural analgesia (PCEA) and patient controlled intravenous analgesia (PCA) after gynecologic oncology surgeries.In this clinical trial study, 90 patients with American society of anesthesiologists (ASA) class I or II scheduled for gynecologic oncologic surgeries were randomly allocated to two groups (45 patients each group) to receive: patient-controlled epidural analgesia with bupivacaine and fentanyl (PCEA group), or patient controlled intravenous analgesia (IV PCA group) with fentanyl, pethidine and ondansetron. Postoperative pain was assessed over 48 hours using the visual analog scale (VAS). The frequency of rescue analgesia was recorded. Occurrence of any concomitant events such as nausea, vomiting, ileus, purities, sedation and respiratory complications were recorded postoperatively.There were no statistically significant differences in demographic data including; age, weight, ASA physical status, duration of surgery, intraoperative bleeding, and the amount of blood transfusion (P > 0.05), between the two studied groups. Severity of postoperative pain was not significantly different between the two groups (P > 0.05); however, after first patient mobilization, pain was significantly lower in the epidural group than the IV group (P < 0.001). There was no significant difference between the two groups regarding the incidence of complications such as nausea, vomiting, purities or ileus (P > 0.05). Nevertheless, the incidence and severity of sedation was significantly higher in the IV group (P < 0.001). Respiratory depression was higher in the IV group than the epidural group; this difference, however, was not significant (P = 0.11). In the epidural group, only 10 patients (22.2%) had mild and transient lower extremities parenthesis.Both intravenous and epidural analgesic techniques with combination of analgesics provide proper postoperative pain control after major gynecologic cancer surgeries without any significant complications. Regarding lower sedative and respiratory depressant effects of epidural analgesia, it seems that this method is a safer technique for postoperative pain relief in these patients.

Project description:BackgroundIrritable bowel syndrome (IBS) is a highly prevalent chronic pain disorder with multiple underlying mechanisms and few treatments that have been demonstrated to be effective in placebo controlled trials. One potential reason may be the use of composite outcomes, such as the IBS Symptom Severity Scale (IBS-SSS) which includes descriptive items related to pain frequency and pain intensity as well as bowel dysfunction and bloating. We investigated if different features of IBS pain have distinct genetic associations and if these may be moderated by sex hormones.Participants and settingAdult outpatients with moderately severe IBS (>175 on IBS-SSS) enrolled in a clinical trial reported IBS-SSS at baseline and after 6 weeks of therapy.MethodsFixed effects modeling was used to test the effect of COMT rs4680 genotype to change in pain severity (rated 0-100) and pain frequency (defined as number of days with pain in the past 10 days) from baseline to week 6 with IBS treatment. Parallel exploratory genome-wide association studies (GWAS) were also performed to identify single nucleotide polymorphisms (SNPs) associated with change in pain severity or pain frequency across all participants.ResultsA total of 212 participants (74% female) were included. The COMT rs4680 met allele was associated with decreased pain severity over the course of the trial in gene dosage models [beta(SE) -5.9 (2.6), P = 0.028]. Exploratory GWAS for change in pain frequency identified 5 SNPs in close proximity on chromosome 18 near L3MBTL4 which reached genome-wide significance (all P < 5.0E-8). This effect was not mediated by changing estradiol levels. There was also a region of chromosome 7 with 24 SNPs of genome-wide suggestive significance for change in pain severity (all P < 1.0E-5).ConclusionsPreviously reported association between COMT rs4680 genotype and treatment response as measured by IBS-SSS is related to pain severity, but not pain frequency. We also identified new candidate genes associated with changes in IBS pain severity (SNX13) and pain frequency (L3MBTL4) in response to treatment. Further studies are needed to understand these associations and genetic determinants of different components of IBS-SSS. ClinicalTrials.gov, Identifier: NCT0280224.

Project description:IntroductionThis study aimed to compare the efficacy between patient-controlled caudal epidural analgesia (PCCA) and patient-controlled intravenous analgesia (PCIA) after perianal surgery, to provide a feasible solution to postoperative pain.MethodsThis was a prospective, randomized controlled trial comprising 100 patients who underwent caudal epidural block on perianal surgery at Chengdu Shang Jin Nan Fu Hospital of West China Hospital at Sichuan University between April and August 2020. Patients were randomly divided into the PCCA and PCIA groups. Visual analog scale (VAS) scores were recorded at 2, 4, 6, 24, 48, and 72 h after surgery, and at the first dressing change and first defecation. The lower limb mobility in the post-anesthetic recovery room (PACU) was determined. The analgesic effect, usage amount of patient-controlled analgesia (PCA), usage amount and frequency of remedial analgesic measures, number of individuals who must be catheterized, and incidence of adverse reactions were recorded. Satisfaction of postoperative analgesic effect and convenience of PCA were also assessed.ResultsThe patients in the PCCA group had significantly lower VAS scores at 4, 6, 24, 48, 72 h, the first dressing change, and the first defecation compared with the PCIA group. There were more patients receiving postoperative remedial analgesics in the PCIA group than in the PCCA group. The outcome of the number of PCA and catheterization rates did not differ significantly between the groups. There were two cases of sensory numbness below the S3 plane. The major postoperative complications in the PCIA group were pruritus (3/47, 6.4%), nausea, and vomiting (6/47, 12.8%) (one case combined with pruritus). Patients in the PCCA group were more satisfied with the analgesic effect, while those in the PCIA group were more satisfied with the convenience.ConclusionIn the postoperative analgesia program of perianal surgery, PCCA may provide a better analgesic effect without increasing the incidence of complications.Trial registrationChinese Clinical Trial Registry identifier, ChiCTR2000038425, September 2020, retrospectively registered.

Project description:BackgroundRectus sheath catheter analgesia (RSCA) and thoracic epidural analgesia (TEA) are both used for analgesia following laparotomy. The aim was to compare the analgesic effectiveness of RSCA with TEA after laparotomy for elective colorectal and urological surgery.MethodsPatients undergoing elective midline laparotomy were randomized in a non-blinded fashion to receive RSCA or TEA for postoperative analgesia at a single UK teaching hospital. The primary quantitative outcome measure was dynamic pain score at 24 h after surgery. A nested qualitative study (reported elsewhere) explored the dual primary outcome of patient experience and acceptability. Secondary outcome measures included rest and movement pain scores over 72 h, functional analgesia, analgesia satisfaction, opiate consumption, functional recovery, morbidity, safety, and cost-effectiveness.ResultsA total of 131 patients were randomized: 66 in the RSCA group and 65 in the TEA group. The median (interquartile range; i.q.r.) dynamic pain score at 24 h was significantly lower after TEA than RSCA (33 (11-60) versus 50.5 (24.50-77.25); P = 0.018). Resting pain score at 72 h was significantly lower after RSCA (4.5 (0.25-13.75) versus 12.5 (2-13); P = 0.019). Opiate consumption on postoperative day 3 (median (i.q.r.) morphine equivalent 17 (10-30) mg versus 40 (13.25-88.50) mg; P = 0.038), hypotension, or vasopressor dependency (29.7 versus 49.2 per cent; P = 0.023) and weight gain to day 3 (median (i.q.r.) 0 (-1-2) kg versus 1 (0-3) kg; P = 0.046) were all significantly greater after TEA, compared with RSCA. There were no significant differences between groups in other secondary outcomes, although more participants experienced serious adverse events after TEA compared with RSCA, which was also the more cost-effective.ConclusionsTEA provided superior initial postoperative analgesia but only for the first 24 h. By 72 hours RSCA provides superior analgesia, is associated with a lower incidence of unwanted effects, and may be more cost-effective.

Project description:BackgroundNeonatal rats exposed to repetitive inflammatory pain have altered behaviors in young adulthood, partly ameliorated by Ketamine analgesia. We examined the relationships between protein expression, neuronal survival and plasticity in the neonatal rat brain, and correlated these changes with adult cognitive behavior.MethodsUsing Western immunoblot techniques, homogenates of cortical tissue were analyzed from neonatal rats 18-20 hours following repeated exposure to 4% formalin injections (F, N = 9), Ketamine (K, 2.5 mg/kg x 2, N = 9), Ketamine prior to formalin (KF, N = 9), or undisturbed controls (C, N = 9). Brain tissues from another cohort of rat pups (F = 11, K = 12, KF = 10, C = 15) were used for cellular staining with Fos immunohistochemistry or FluoroJade-B (FJB), followed by cell counting in eleven cortical and three hippocampal areas. Long-term cognitive testing using a delayed non-match to sample (DNMS) paradigm in the 8-arm radial maze was performed in adult rats receiving the same treatments (F = 20, K = 24, KF = 21, C = 27) in the neonatal period.ResultsGreater cell death occurred in F vs. C, K, KF in parietal and retrosplenial areas, vs. K, KF in piriform, temporal, and occipital areas, vs. C, K in frontal and hindlimb areas. In retrosplenial cortex, less Fos expression occurred in F vs. C, KF. Cell death correlated inversely with Fos expression in piriform, retrosplenial, and occipital areas, but only in F. Cortical expression of glial fibrillary acidic protein (GFAP) was elevated in F, K and KF vs. C. No significant differences occurred in Caspase-3, Bax, and Bcl-2 expression between groups, but cellular changes in cortical areas were significantly correlated with protein expression patterns. Cluster analysis of the frequencies and durations of behaviors grouped them as exploratory, learning, preparatory, consumptive, and foraging behaviors. Neonatal inflammatory pain exposure reduced exploratory behaviors in adult males, learning and preparatory behaviors in females, whereas Ketamine ameliorated these long-term effects.ConclusionNeuroprotective effects of Ketamine attenuate the impaired cognitive behaviors resulting from pain-induced cell death in the cortical and hippocampal fields of neonatal rats. This cell death was not dependent on the apoptosis associated proteins, but was correlated with glial activation.

Project description:ImportancePain is a common out-of-hospital symptom among patients, and opioids are often prescribed. Research suggests that overprescribing for acute traumatic pain is still prevalent, even when limits restricting opioid prescriptions have been implemented. Ketamine hydrochloride is an alternative to opioids in adults with out-of-hospital traumatic pain.ObjectiveTo assess the noninferiority of intravenous ketamine compared with intravenous morphine sulfate to provide pain relief in adults with out-of-hospital traumatic pain.Design, setting, and participantsThe Intravenous Subdissociative-Dose Ketamine Versus Morphine for Prehospital Analgesia (KETAMORPH) study was a multicenter, single-blind, noninferiority randomized clinical trial comparing ketamine hydrochloride (20 mg, followed by 10 mg every 5 minutes) with morphine sulfate (2 or 3 mg every 5 minutes) in adult patients with out-of-hospital trauma and a verbal pain score equal to or greater than 5. Enrollment occurred from November 23, 2017, to November 26, 2022, in 11 French out-of-hospital emergency medical units.InterventionsPatients were randomly assigned to ketamine (n = 128) or morphine (n = 123).Main outcomes and measuresThe primary outcome was the between-group difference in mean change in verbal rating scale pain scores measured from the time before administration of the study drug to 30 minutes later. A noninferiority margin of 1.3 was chosen.ResultsA total of 251 patients were randomized (median age, 51 [IQR, 34-69] years; 111 women [44.9%] and 140 men [55.1%] among the 247 with data available) and were included in the intention-to-treat population. The mean pain score change was -3.7 (95% CI, -4.2 to -3.2) in the ketamine group compared with -3.8 (95% CI, -4.2 to -3.4) in the morphine group. The difference in mean pain score change was 0.1 (95% CI, -0.7 to 0.9) points. There were no clinically meaningful differences for vital signs between the 2 groups. The intravenous morphine group had 19 of 113 (16.8% [95% CI, 10.4%-25.0%]) adverse effects reported (most commonly nausea [12 of 113 (10.6%)]) compared with 49 of 120 (40.8% [95% CI, 32.0%-49.6%]) in the ketamine group (most commonly emergence phenomenon [24 of 120 (20.0%)]). No adverse events required intervention.Conclusions and relevanceIn the KETAMORPH study of patients with out-of-hospital traumatic pain, the use of intravenous ketamine compared with morphine showed noninferiority for pain reduction. In the ongoing opioid crisis, ketamine administered alone is an alternative to opioids in adults with out-of-hospital traumatic pain.Trial registrationClinicalTrials.gov Identifier: NCT03236805.
