“…Excessive mesentery stretching may increase the risk of mesenteric tear and bowel perforation during insertion. [ 3 ] In the present study, 91.1% of patients acquired painless intubation (VAS = 0), the VAS score of other patients is 1-2 points. These findings suggested that using transnasal gastroscope for colon examination was almost painless and was very safe.…”

“…CO 2 insu ation induces less postprocedural pain compared with nitrogen due to more rapid absorption. (20) The incidence of cardiorespiratory events were similar in both groups. Hypoxia secondary to respiratory depression and airway obstruction is the most frequent complication of PSA during colonoscopy.…”

Background: Procedural sedation and analgesia (PSA) is used during colonoscopy to facilitate the procedure and relieve patient’s discomfort. The foremost risk of PSA is respiratory depression. Lidocaine could be a promising additional analgesic in IBD patients to minimise side effects of PSA.Our primary objective was to investigate whether i.v. lidocaine reduces the amount of alfentanil used during PSA in IBD patients. Additionally, we investigated whether lidocaine reduces cardiorespiratory incidents and the amount of propofol required during the procedure.Methods: A randomised, double-blind, placebo controlled study was performed at the endoscopy unit of the Radboud University Medical Centre from November 2016 to December 2018. Seventy-six patients with IBD, ASA 1 or 2, between 18 and 65 years, scheduled for colonoscopy with PSA were included. Patients received lidocaine 1.5 mg kg-1 followed by a continuous infusion of 2 mg kg-1 h-1 (intervention group, n=38) or 0.9% saline in equivalent volumes (control group, n=38) during colonoscopy.Results: There was a reduction in the use of alfentanil (327µg (95%CI=-31-505, p=0.082)), and propofol (39 mg (95%CI=-5-83, p=0.083)) in the lidocaine group compared with the control group. Ten patients (26%) in the control group and 8 patients in the lidocaine group (21%) experienced a period of hypoxia (p=0.788). In both groups, no periods of hypotension were noted.Conclusion: Our investigation has shown a reduction in the use of propofol and alfentanil in patients undergoing colonoscopy with PSA. The differences were not statistically significant. Lidocaine did not reduces the incidence of cardiorespiratory events.Trial registration:EudraCT, 2016-002210-46, registered 19 may 2016,https://www.clinicaltrialsregister.eu/ctr-search/trial/2016-002210-46/resultsISRCTN, ISRCTN47787339, retrospectively registered 6 February 2019, http://www.isrctn.com/ISRCTN47787339

“…[ 24 , 25 ] This technique can be tried in unsedated patients with IDS > 1. Secondly, CO2 insufflation, the use of small-caliber endoscopes or cap-assisted colonoscopy [ 26 ] may be helpful to alleviate pain. Lastly, sedation can ensure patients painless during the whole procedure.…”

A novel intubation discomfort score to predict painful unsedated colonoscopy

Pain during colonoscopy is a critical quality indicator and often a limiting factor for unsedated colonoscopy. This study aimed to identify factors associated with pain during colonoscopy and establish a model for predicting a painful colonoscopy. Patients aged 18 to 80 who underwent unsedated colonoscopy were prospectively enrolled in 2 tertiary endoscopic centers in China. The primary outcome was the rate of painful colonoscopy and then we identify high-risk factors associated with painful colonoscopy. A prediction model with an intubation discomfort score (IDS) was developed and validated. Totally 607 patients participated in this study, including 345 in the training cohort and 262 in the validation cohort. Body mass index (BMI) of <18.5 kg/m 2 (OR 2.18, 95% CI: 1.09–4.37), constipation (OR 2.45, 95% CI: 1.25–4.80), and anticipating moderate or severe pain (OR 2.06, 95% CI: 1.12–3.79) were identified as independent predictive factors for painful colonoscopy and used to develop the IDS (all P < .05). Patients with IDS ≥1 had increased insertion time [9.32(6.2–13.7)] minutes vs 6.87(5.1–10.4) minutes, P = .038) and decreased cecal intubation rate (96.0% vs 99.6%, P = .044). Abdominal compression (48.4% vs 19.9%, P < .001) and position change (59.7% vs 32.1%, P < .001) were more frequently required in the group of patients with IDS ≥1. These results were externally validated in a validation cohort. The intubation discomfort score developed in this study was useful for predicting pain during colonoscopy, with IDS ≥1 indicating painful colonoscopy.
