Supraglottic jet oxygenation and ventilation improves oxygenation during endoscopic retrograde cholangiopancreatography: a randomized controlled clinical trial.

ABSTRACT:

Purpose

Hypoxia is one of the most frequent adverse events under deep sedation in the semiprone position. We hypothesized that supraglottic jet oxygenation and ventilation (SJOV) via Wei nasal jet tube (WNJ) can reduce the incidence of hypoxia in patients under deep sedation during endoscopic retrograde cholangiopancreatography (ERCP).

Methods

A total of 171 patients were divided into three groups: N group, supplementary oxygen via a nasopharyngeal airway (4-6 L/min); W group, supplementary oxygen via WNJ (4-6 L/min); WS group, SJOV via WNJ. The primary outcome was the incidence of adverse events, including sedation-related adverse events [SRAEs, hypoxemia (SpO₂ = 75-89% lasted less than 60 s); severe hypoxemia (SpO₂ < 75% at any time or SpO₂ < 90% lasted more than 60 s] and subclinical respiratory depression (SpO₂ = 90-95%). Other intraoperative and post-operative adverse events were also recorded as secondary outcomes.

Results

Compared with the N group, the incidence of hypoxemia and subclinical respiratory depression in the WS group was significantly lower (21% vs. 4%, P = 0.005; 27% vs. 6%, P = 0.002). Compared with Group W, the incidence of hypoxemia and subclinical respiratory depression in Group WS was also significantly less frequent (20% vs. 4%, P = 0.009; 21% vs. 6%, P = 0.014). No severe hypoxia occurred in the group WS, while four and one instances were observed in the group N and group W respectively. There were no significant differences in other adverse events among the three groups.

Conclusion

SJOV can effectively improve oxygenation during ERCP in deeply sedated semiprone patients.

Project description:BackgroundHypobaric hypoxia is common at high altitudes. Whether this exacerbates hypoxia during procedural sedation and whether hypoxia can be alleviated by the use of supraglottic jet oxygenation and ventilation (SJOV) are unknown. This study aimed to compare the incidence of hypoxia during gastrointestinal endoscopy under deep sedation at high altitudes with oxygen supply techniques using either a nasal cannula or SJOV.MethodsThis study was conducted from April 2022 to July 2022 in a tertiary hospital located 3650 m above sea level. Adult patients scheduled for routine gastrointestinal endoscopy under sedation were enrolled and randomized 1:1 to receive SJOV or a nasal cannula during sedation. Moderate hypoxia was the primary outcome, defined as an SPO2 of 75-89% for < 60 s. The secondary outcomes were respiratory-, cardiovascular-, and SJOV-related complications. The influence of characteristics regarding acclimatization to high altitudes (Tibetan ethnic group and erythrocytosis) on the occurrence of hypoxia was analyzed.ResultsNone of the patients were lost to follow-up. A total of 72 patients were included in the analysis (36 patients in each group). There were 20 (27.8%) patients who experienced moderate hypoxia events. Significantly fewer hypoxic events occurred in the SJOV group than in the nasal cannula group [3 (8.3%) vs. 17 (47.2%), absolute risk difference (95% CI): - 38.9 (- 57.5, - 20.2) %, risk ratio (RR, 95% CI): 0.18 (0.06, 0.55), P < 0.001]. Significantly fewer patients in the SJOV group experienced mild hypoxia (P < 0.001) and severe hypoxia (P = 0.002). No serious adverse events occurred in either of the groups. The Tibetan ethnic group (P = 0.086) and erythrocytosis (P = 0.287) were not associated with the occurrence of hypoxia events.ConclusionsThe incidence of hypoxia was lower with SJOV than with nasal cannula in patients undergoing gastrointestinal endoscopy under deep sedation at high altitudes. The Tibetan ethnic group and erythrocytosis did not influence the occurrence of hypoxia.Trial registrationThis study was registered at ClinicalTrials.gov (NCT05304923) before enrollment by Dr. Yi Feng on 31/03/2022.

Project description:IntroductionHypoxemia is a common complication of sedation. This meta-analysis aimed to evaluate the efficacy and safety of supraglottic jet oxygenation and ventilation (SJOV) in preventing hypoxemia during sedative procedures.MethodsRandomized controlled trials (RCTs) that compared SJOV with conventional oxygen therapy in sedated patients were searched in five databases (MEDLINE, EMBASE, Cochrane Library, China National Knowledge Infrastructure [CNKI], and Google Scholar) from their inception to March 2024. The primary outcome was the proportion of patients who developed hypoxia (SpO2 < 90%). The secondary outcomes included subclinical respiratory depression (90% ≤ SpO2 < 95%), severe hypoxemia (SpO2 < 75%), airway interventions, adverse events, hemodynamics, propofol dosage, and procedure time. The certainty of evidence was determined using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.ResultsTwelve trials (n = 3058) were included in the analysis. The evidence suggests that SJOV results in a large reduction in the risk of hypoxemia (risk ratio [RR], 0.26; 95% confidence interval, 0.19-0.36; low certainty) and subclinical respiratory depression (RR, 0.40; low certainty) compared with the control. SJOV likely resulted in a large reduction in the risk of severe hypoxemia (RR, 0.22; moderate certainty). In addition, it may result in a large reduction in the need for jaw lift (RR, 0.22; low certainty) and mask ventilation (RR, 0.13; low certainty). The risk of sore throat probably increases with SJOV (RR, 1.71; moderate certainty), whereas SJOV may result in little to no difference in nasal bleeding (RR, 1.75; low certainty). Evidence is very uncertain regarding the effect of SJOV on hemodynamics (very low certainty) and procedure time (very low certainty). SJOV probably resulted in little to no difference in sedative doses between the groups (moderate certainty).ConclusionAccording to the GRADE approach, SJOV likely results in a large reduction in the risk of severe hypoxemia but probably increases the risk of sore throat. Compared with the control, evidence suggests that SJOV results in a large reduction in the risk of hypoxemia, subclinical respiratory depression, and the need for airway manipulation, with little to no difference in nasal bleeding. The integration of SJOV into clinical practice may help minimize hypoxemic events in at-risk patients.

Project description:BackgroundEndoscopic Retrograde Cholangiopancreatography (ERCP) is a complex endoscopic procedure that requires moderate to deep sedation. Propofol is the sedative agent of choice for sedation in ERCP due to its fast distribution and fast elimination time without a cumulative effect after infusion, resulting in shorter recovery time. Benzydamine hydrochloride is a topical non-steroidal anti-inflammatory drug that has analgesic, local anesthetic, and anti-inflammatory effects that have been known to be effective in reducing postoperative sore throat. Combination of propofol and topical analgesic may provide adequate sedation and reduce propofol consumption. This study aimed to determine the effectivity of benzydamine hydrochloride gargling in reducing propofol consumption in the ERCP procedure.MethodsThis study was a single-blind randomized controlled trial for patients undergoing ERCP procedures at Cipto Mangunkusumo Hospital from August to September 2018. A total of 72 subjects were recruited consecutively and randomly assigned into two groups. The first group received 15 mL of 0.15% benzydamine hydrochloride mouthwash prior to the procedure, whereas the second group received 15 mL of water mouthwash. Additional propofol was administered when patient moved or Ramsay Sedation Scale rose above 4. Cumulative propofol consumption per kg body weight per minute and incidence of postoperative sore throat were recorded in each group. Incidence of desaturation, postoperative nausea vomitting, and dysphagia were also recorded. Data analysis was performed with Statistical Package for the Social Sciences.ResultsCumulative propofol consumption per minute per kg body weight in the benzydamine hydrochloride group was 152.7 (91.9-238.8) mcg/kg/minute, while in the control group was 200.05 (114.4-380.2) mcg/kg/ minute (p = < 0.001). The incidence of sore throat on the 0th, 2nd, and 4th hour for the benzydamine hydrochloride group was 11.4, 11.4, and 5.7%, while in the control group was 50, 52.8, and 36.1% (p = < 0.001, < 0.001, 0.003). Desaturation was found in control group whereas none in benzydamine hydrochloride group. Complaints of nausea and vomiting were comparable in both groups.ConclusionBenzydamine hydrochloride gargling was effective in reducing cumulative propofol consumption in the ERCP procedure.Trial registrationStudy was registered retrospectively in ClinicalTrials.gov with NCT04167592 on November 8th 2019.

Project description:BackgroundPancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP) which can be severe and cause death in approximately 10% of cases. Up to now, six randomized controlled trials (RCTs) have been found relevant to the effect of allopurinol on prevention of Post-ERCP pancreatitis (PEP). However, these results remained controversial.ObjectiveTo conduct a meta-analysis with RCTs published in full text to determine the effectiveness of prophylactic allopurinol of different dosages and administration time in the incidence and severity of PEP.MethodsLiterature search was performed in PubMed, Embase, Web of Science and Cochrane Library from databases inception to May 2014. RCTs comparing the effect of allopurinol with placebo on prevention of PEP were included. Statistical heterogeneity was quantitatively evaluated byχ2 test with the significance set P<0.10 or I2>50%.ResultsSix RCTs consisting of 1974 participants were eventually included. The incidences of PEP in allopurinol group and placebo group were 8.4%(83/986) and 9.9%(98/988) respectively. Meta-analysis showed no evident prevention effect of allopurinol on the incidence of PEP (RR 0.75, 95%CI 0.39-1.42) with significant heterogeneity (I2 = 70.4%, P = 0.005). When studies were stratified according to the dosages and administration time of allopurinol they applied, there was still no evident prevention effect of allopurinol on mild, moderate or severe PEP. However, statistically substantial heterogeneity was presented in the subgroup of moderate PEP when the effect of high dose of allopurinol was analyzed (Imoderate2 = 82.3%, Pmoderate = 0.018). Statistically significant heterogeneity was also observed in subgroup of mild PEP, when the effect of long adminstration time of allopurinol was investigated (Imild2 = 62.8%, Pmild = 0.068).ConclusionThe prophylactic use of allopurinol in different dosages and administration time had no effect in preventing incidence and severity of PEP.
