Comparison of the safety of the application of painless gastroscopy and ordinary gastroscopy in chronic hypertension patients combined with early gastric cancer

The 50% effective dose of remimazolam combined with different doses of esketamine for painless gastroscopy

OBJECTIVE

Remimazolam is a novel benzodiazepine sedative that provides effective sedation, stable haemodynamics, and minimal adverse effects during intravenous general anaesthesia. The aim of this study was to determine the 50% effective dose (ED50) of remimazolam combined with different doses of esketamine for painless gastroscopy and to evaluate the efficacy and safety of this combination.

METHODS

This was a randomised, double-blind, up-and-down sequential allocation study. Patients undergoing painless gastroscopy who met all the inclusion criteria and did not meet any of the exclusion criteria were randomised in a 1:1:1 ratio into the ES0 group (0 mg/kg of esketamine), ES1 group (0.2 mg/kg of esketamine), and ES2 group (0.4 mg/kg of esketamine). The initial dose of remimazolam was 0.3 mg/kg in each group, with the dose increased or decreased by 0.05 mg/kg for the subsequent patient based on the success or failure of sedation in the previous patient. The trial was concluded when seven successful failure crossovers were achieved. The ED50 and 95% confidence intervals (CI) of remimazolam were calculated using Probit regression. Haemodynamic parameters, time to induction of anaesthesia, time to gastroscopy, time to awakening from anaesthesia, and adverse events were recorded.

RESULTS

A total of 59 patients were included in the final analysis: 19 in the ES0 group, 23 in the ES1 group, and 17 in the ES2 group. The ED50 (95% CI) of remimazolam in the ES0, ES1, and ES2 groups was 0.344 (0.302-0.389) mg/kg, 0.289 (0.249-0.328) mg/kg, and 0.193 (0.145-0.239) mg/kg, respectively. Additionally, the ES1 and ES2 groups exhibited more stable haemodynamics compared to the ES0 group. However, the ES1 and ES2 groups had significantly longer recovery times than the ES0 group. The incidence of hypotension was higher in the ES0 group compared to the ES1 and ES2 groups.

CONCLUSION

The ED50 of remimazolam combined with 0 mg/kg, 0.2 mg/kg, and 0.4 mg/kg of esketamine for induction of anaesthesia during painless gastroscopy was 0.344 mg/kg, 0.289 mg/kg, and 0.193 mg/kg, respectively. Combining esketamine with remimazolam for induction of anaesthesia during painless gastroscopy offers advantages in terms of haemodynamic stability and reduced adverse effects.

Effect of anxiety-targeted care combined with seamless care on psychological status, stress response in patients undergoing gastroscopy

This study aimed to analyze the feasibility of anxiety-targeted care combined with seamless care for patients undergoing gastroscopy, and to investigate its effects on patients' psychological state, stress response and examination results. 120 patients undergoing gastroscopy were divided into a study group (anxiety care + seamless care, 70 cases) and a control group (routine care, 50 cases). The differences in SAS and SDS scores before the intervention did not differ between two groups (p > 0.05) and they were lower in observation group than in control group after the intervention (p < 0.05); The heart rate, systolic and diastolic blood pressure of patients in the study group were significantly lower than those in the control group at 10 min before intubation (T0), upon intubation (T1), 1 min after intubation (T2) and upon extubation (T3) (p < 0.05); The mean time to intubation was shorter and first-pass intubation success rate was higher in the study group than in the control group (p < 0.05); The complication rate in the study group was significantly lower than that in the control group (4.29% vs 16.00) (p < 0.05). Anxiety care combined with seamless care is feasible for patients undergoing gastroscopy.

Sedated and unsedated gastroscopy has no influence on the outcomes of patients with gastric cancer: a retrospective study

BACKGROUND

Different anesthetic drugs and techniques may affect survival outcomes for gastric cancer (GC) after surgery. In this study, we investigated the association between sedated and unsedated gastroscopy on survival outcomes in patients with GC after surgery.

METHODS

This was a retrospective study of patients who were diagnosed with GC by gastroscopy and underwent gastrectomy from January 2013 to December 2017. They were grouped based on the examination modality: propofol-based sedated gastroscopy or unsedated gastroscopy. Propensity score matching (PSM) was used to balance the baseline variables. Survival outcomes and distant metastases were compared between these two groups.

RESULTS

Finally, 673 patients were enrolled, 160 in the sedated gastroscopy group and 513 in the unsedated gastroscopy group. After PSM, there were 160 patients in each group. There was no significant difference in overall survival outcomes in the sedated gastroscopy group compared to the unsedated gastroscopy group before PSM (HR = 0.761, 95% CI: 0.531-1.091, P = 0.139) or after PSM (HR = 0.874, 95% CI: 0.564-1.355, P = 0.547). There was no significant difference in the incidence of distant metastases between the two groups before PSM (16.9% vs. 20.7%, P = 0.294) or after PSM (16.9% vs. 23.8%, P = 0.126). To confirm that our patients behaved similarly to other studies, we performed a multivariate analysis and the results showed that sex, pathological TNM stage, Borrmann type, adjuvant treatment, and surgical resection range were all independent factors affecting survival outcomes in our patients.

CONCLUSION

Our results showed no significant difference in the effects of sedated gastroscopy vs. unsedated gastroscopy on survival outcomes or distant metastases of patients after gastrectomy for GC.

The impact of early gastroscopy examination on cardiovascular event-related indices in elderly patients with acute upper gastrointestinal bleeding

BACKGROUND

To observe the effects of early gastroscopy examination on cardiovascular event-related indicators such as heart rate (HR), blood pressure, and electrocardiogram (ECG) in elderly patients with acute upper gastrointestinal bleeding.

METHODS

Sixty patients with upper gastrointestinal bleeding admitted from July 2022 to December 2022 were selected. Patients with relevant contraindications were excluded. All patients underwent early gastroscopy examination. Among them, 30 patients were aged 60 or above (elderly group) and 30 patients were aged below 60 (non-elderly group). Dynamic blood pressure and ECG recordings were obtained before, during, and after gastroscopy examination to assess changes in HR, blood pressure, and ECG.

RESULTS

The HR and blood pressure levels of the elderly group were significantly lower than those of the non-elderly group before, during, and after gastroscopy examination (P < .05). In the elderly group, blood pressure and HR were higher during gastroscopy examination compared to before, but lower than during the examination afterward, with statistically significant differences (P < .05). The diastolic blood pressure was lower after the examination compared to before, with statistical significance, while the systolic blood pressure was lower, and the HR was higher after the examination, but without statistical significance (P > .05). In the non-elderly group, systolic blood pressure and HR were higher during gastroscopy examination compared to before, with statistically significant differences (P < .05), while diastolic blood pressure was higher but without statistical significance (P > .05). Blood pressure and HR were lower after the examination compared to during, with statistically significant differences (P < .05). The occurrence rates of ECG changes were 70% in the elderly group and 30% in the non-elderly group, with a statistically significant difference (χ2 = 5.45, P = .02 < .05).

CONCLUSION

Early gastroscopy examination in elderly patients with gastrointestinal bleeding did not result in severe cardiovascular adverse events and was relatively safe. However, special attention should be given to the occurrence of cardiac arrhythmias.

Efficacy and safety of gastroscopic hemostasis in the treatment of acute gastric hemorrhage: A meta-analysis

BACKGROUND

Gastric cancer (GC) is a malignant tumor with a high incidence and mortality rate worldwide for which acute bleeding is a common clinical complication. Gastroscopic hemostasis is an important method for treating acute bleeding in GC; however, its efficacy and safety remain controversial.

AIM

To systematically analyze the efficacy and safety of gastroscopic hemostasis for the treatment of acute gastric hemorrhage.

METHODS

The PUBMED, Web of Science, Wiley Library, EMBASE, Wanfang, CNKI, and VIP databases were searched for studies related to gastroscopic hemostatic treatment for acute GC published through February 20, 2023. The literature was screened according to the inclusion and exclusion criteria, data were extracted, and literature quality was evaluated. The meta-analysis was performed using RevMan software (version 5.3), while Begg’s test for publication bias was performed using Stata 13.0 software.

RESULTS

Six randomized controlled trials and two retrospective analyses were retrieved. Five studies had a low, two had an uncertain, and one had a high risk of bias. Compared with the control group, the hemostatic rate of gastroscopic hemostasis was increased [relative risk (RR) = 1.24; 95% confidence interval (CI): 1.08 to 1.43; P = 0.003]; the rate of rebleeding (RR = 0.27; 95%CI: 0.09 to 0.80; P = 0.02), rate of surgery transfer (RR = 0.16; 95%CI: 0.06 to 0.43; P = 0.0003), serum C-reactive protein level [mean difference (MD) = -5.16; 95%CI: -6.11 to 4.21; P < 0.00001], interleukin-6 level (MD = -6.37; 95%CI: -10.33 to -2.42; P = 0.002), and tumor necrosis factor-α level (MD = -2.29; 95%CI: -4.06 to -0.52; P = 0.01) were decreased; and the quality of life improvement rate was increased (RR = 1.95; 95%C I= 1.41-2.71; P < 0.0001). Begg’s test revealed no significant publication bias.

CONCLUSION

The efficacy and safety of endoscopic hemostasis were higher than those of the control group, suggesting that it is an effective treatment for acute GC hemorrhage.

Effects of propofol combined with sufentanil on painless gastroscopy and hemodynamics in children under general anesthesia

OBJECTIVE

To determine the effects of propofol combined with sufentanil on painless gastroscopy and hemodynamics in children under general anesthesia.

METHODS

The data of 98 children who received painless gastroscopy in the Children's Hospital of Nanjing Medical University from May 2022 and November 2022 were analyzed retrospectively. Patients anesthetized with propofol (1.5-2 mg/kg) combined with sufentanil (0.03-0.05 μg/kg) were assigned to a study group (n=52), and patients anesthetized with propofol (1.5-2 mg/kg) combined with fentanyl (0.3-0.5 µg/kg) were included in a control group (n=46). The changes in hemodynamic levels (mean arterial pressure (MAP), heart rate (HR) and pulse oxygen saturation (SpO2) at T0 (before anesthesia), T1 (1 min after anesthesia induction), T2 (start of examination), T3 (2 min after the start of examination), and T4 (end of examination) in the two groups were analyzed and compared. The Ramsay sedation score was adopted to evaluate the sedation of the two groups at the anesthesia recovery and at 1 h and 2 h after the anesthesia recovery. The anesthetic effects (time to loss of consciousness, eye opening, and recovery of orientations) of the two groups were analyzed and compared. The excellent and good anesthesia outcomes, hospitalization time and dosage of propofol were compared between the two groups, and the adverse reactions in the two groups during and after the examination were analyzed.

RESULTS

At T0, the two groups were not significantly different in the levels of MAP, HR and SpO2 (P>0.05), but at T1, T2, T3, and T4, the study group showed a significantly higher MAP level than the control group (P<0.05). At T1 and T3, the study group exhibited a significantly higher HR level than the control group (P<0.05), and at T2 and T4, the HR level of the two groups was not greatly different (P>0.05). The SpO2 levels at T0, T1, T2, T3, and T4 were not greatly different between the two groups (P>0.05). There was no significant difference in Ramsay score between the two groups at anesthesia recovery and at 1 h and 2 h after the anesthesia recovery (P>0.05). Additionally, the study group experienced significantly earlier time to loss of consciousness, eye opening, and recovery of orientations than the control group (P<0.05). The number of patients with excellent anesthetic outcome in the study group was notably higher than that in the control group (P<0.05). Compared with the control group, the study group consumed less propofol, experienced shorter hospitalization time, and showed a notably lower incidence of adverse reactions (P<0.05).

CONCLUSION

For children undergoing painless gastroscopy under general anesthesia, sufentanil combined with propofol can deliver better anesthetic effect than propofol combined with fentanyl, with less effect on hemodynamics and fewer gastroscopy-related adverse reactions.

Effect of modified ShengYangYiwei decoction on painless gastroscopy and gastrointestinal and immune function in gastric cancer patients

BACKGROUND

Painless gastroenteroscopy is a widely developed diagnostic and treatment technology in clinical practice. It is of great significance in the clinical diagnosis, treatment, follow-up review and other aspects of gastric cancer patients. The application of anesthesia techniques during manipulation can be effective in reducing patient fear and discomfort. In clinical work, the adverse drug reactions of anesthesia regimens and the risk of serious adverse drug reactions are increased with the increase in propofol application dose application dose; the application of opioid drugs often causes gastrointestinal reactions, such as nausea, vomiting and delayed gastrointestinal function recovery, after examination. These adverse effects can seriously affect the quality of life of patients.

AIM

To observe the effect of modified ShengYangYiwei decoction on gastrointestinal function, related complications and immune function in patients with gastric cancer during and after painless gastroscopy.

METHODS

A total of 106 patients with gastric cancer, who were selected from January 2022 to September 2022 in Xiamen Traditional Chinese Medicine Hospital for painless gastroscopy, were randomly divided into a treatment group (n = 56) and a control group (n = 50). Before the examination, all patients fasted for 8 h, provided their health education, and confirmed if there were contraindications to anesthesia and gastroscopy. During the examination, the patients were placed in the left decubitus position, the patients were given oxygen through a nasal catheter (6 L/min), the welling needle was opened for the venous channel, and a multifunction detector was connected for monitoring electrocardiogram, oxygen saturation, blood pressure, etc. Naporphl and propofol propofol protocols were used for routine anesthesia. Before anesthesia administration, the patients underwent several deep breathing exercises, received intravenous nalbuphine [0.nalbuphine (0.025 mg/kg)], followed by intravenous propofol [1.propofol (1.5 mg/kg)] until the palpebral reflex disappeared, and after no response, gastroscopy was performed. If palpebral reflex disappeared, and after no response, gastroscopy was performed. If any patient developed movement, frowning, or hemodynamic changes during the operation (heart rate changes during the operation (heart rate increased to > 20 beats/min, systolic blood pressure increased to > 20% of the base value), additional propofol [0.propofol (0.5 mg/kg)] was added until the patient was sedated again. The patients in the treatment group began to take the preventive intervention of Modified ShengYangYiwei decoction one week before the examination, while the patients in the control group received routine gastrointestinal endoscopy. The patients in the two groups were examined by conventional painless gastroscopy, and the characteristics of the painless gastroscopies of the patients in the two groups were recorded and compared. These characteristics included the total dosage of propofol during the examination, the incidence of complications during the operation, the time of patients' awakening, the time of independent activities, and the gastrointestinal function of the patients after examination, such as the incidence of reactions such as malignant vomiting, abdominal distension and abdominal pain, as well as the differences in the levels of various immunological indicators and inflammatory factors before anesthesia induction (T0), after conscious extubation (T1) and 24 h after surgery (T2).

RESULTS

There was no difference in the patients’ general information, American Society of Anesthesiologist classification or operation time between the two groups before treatment. In terms of painless gastroscopy, the total dosage of propofol in the treatment group was lower than that in the control group (P < 0.05), and the time of awakening and autonomous activity was significantly faster than that in the control group (P < 0.05). During the examination, the incidence of hypoxemia, hypotension and hiccups in the treatment group was significantly lower than that in the control group (P < 0.01). In terms of gastrointestinal function, the incidences of nausea, vomiting, abdominal distension and abdominal pain in the treatment group after examination were significantly lower than those in the control group (P < 0.01). In terms of immune function, in both groups, the number of CD4+ and CD8+ cells decreased significantly (P < 0.05), and the number of natural killer cells increased significantly (P < 0.05) at T1 and T2, compared with T0. The number of CD4+ and CD8+ cells in the treatment group at the T1 and T2 time points was higher than that in the control group (P < 0.05), while the number of natural killer cells was lower than that in the control group (P < 0.05). In terms of inflammatory factors, compared with T0, the levels of interleukin (IL) -6 and tumor necrosis factor-alpha in patients in the two groups at T1 and T2 increased significantly and then decreased (P < 0.05). The level of IL-6 at T1 and T2 in the treatment group was lower than that in the control group (P < 0.05).

CONCLUSION

The preoperative use of modified ShengYangYiwei decoction can optimize the anesthesia program during painless gastroscopy, improve the gastrointestinal function of patients after the operation, reduce the occurrence of examination-related complications.

Outcome of Nursing Based on Health Belief United with Knowledge, Belief, and Practice Mode on Gastroscopy of Patients with Gastric Cancer

Aim

If gastric cancer can be detected through early screening, and scientific and reasonable intervention methods can be selected in time, the condition can be effectively controlled. Routine nursing has been unable to obtain satisfactory results, and the effect on improving the compliance of the examiner is not outstanding. The research aims to estimate the outcome of nursing based on health belief combined with knowledge, belief, and practice on gastroscopy in patients with gastric cancer.

Methods

126 patients with clinically diagnosed gastric cancer in the Number Two Hospital of Baoding from May 2020 to May 2022 were randomly divided into belief guidance group and mode group, with 63 instances each. The mode group was intervened via the mode of knowledge, belief, and practice, and the belief guidance group was intervened via the nursing based on health belief on the basis of the mode group. Before and after the nursing, the health belief, examination compliance, inappropriateness, and negative emotion in different time periods were contrasted between the two groups.

Results

After the nursing, the scores of health belief scale in the belief guidance group were enhanced than those in the mode group; the compliance rate of the belief guidance group was markedly enhanced than that of the mode group, and the inappropriateness during the insertion and examination was lower than that of the mode group; the scores of self-rating anxiety scale (SAS) and self-rating depression scale (SDS) in the two groups preinsertion and postnursing were markedly lower than those in the mode group.

Conclusion

Nursing based on health belief guidance united with knowledge, belief, and practice mode nursing can advance the health belief and compliance of gastroscopy in patients with gastric cancer, reduce discomfort, and effectively advance the negative emotions of patients. It is worthy of clinical application.

Comparison of the innovative endoscopic oropharyngeal airway and the conventional mouthpiece in elderly outpatients undergoing esophagogastroduodenoscopy under sedation: a prospective and randomized study

Background

Undesirable outcomes may appear for elderly patients undergoing esophagogastroduodenoscopy (EGD) under sedation, such as hypoxia and hypotension. The aim of our study was to investigate the ability of the innovative endoscopic oropharyngeal airway to reduce the frequency of hypoxia during EGD under sedation in elderly patients.

Methods

In this trial, aged patients undergoing EGD were randomized into airway group and mouthpiece group. The primary outcome was the incidence of the minimum pulse oxygen saturation < 90% and minimum pulse oxygen saturation. In addition, sedation dose, recovery time, emergency management and adverse reactions were recorded.

Results

360 patients completed the study (180 in each groups). The minimum pulse oxygen saturation during EGD was significantly higher in airway group (97.66 ± 2.96%) than in mouthpiece group (95.52 ± 3.84%, P < 0.001). The incidence of pulse oxygen saturation of 85–89% of airway group (5.0%, 9/180) was lower than mouthpiece group (10.6%, 19/180, P = 0.049). The endoscopy entry time in airway group was 3 (2, 4) seconds and in mouthpiece group was 5 (4, 6) (P < 0.001). Propofol total dose and awakening time were significantly lower in the airway group than in the mouthpiece group (P = 0.020 and P = 0.012, respectively). Furthermore, the incidence rate of hypotension was significantly higher in mouthpiece group (12.2%) than in airway group (5.0%) (P = 0.015). By comparison with the mouthpiece group, the satisfaction of endoscopists was higher in airway group (P = 0.012).

Conclusion

Elderly patients undergoing EGD, Endoscopy Protector was associated with a significantly lower incidence of hypoxia, shortened endoscopy entry time and more stable hemodynamics.

Analysis of gastroscopy results among healthy people undergoing a medical checkup: a retrospective study

Background

The association of upper gastrointestinal endoscopic findings with sex, age, and Helicobacter pylori infection in asymptomatic healthy people is unclear. The aim of this study was to retrospectively determine the associations of upper gastrointestinal endoscopic findings in asymptomatic healthy people with sex, age, and H. pylori infection.

Methods

A retrospective study was conducted on 2923 patients from a health examination center in Xiangya Hospital between September 2015 and September 2019. Data on sex, age, H. pylori infection, and gastroscopy results were collected.

Results

Among 2923 asymptomatic patients who underwent gastroscopy, 2911 (99.59%) had abnormal results. The top three results were chronic gastritis (95.11%), peptic ulcer (17.45%), and duodenitis (9.17%). Inflammation of the gastric mucosa in chronic gastritis was more severe in the H. pylori-positive group. The incidence of peptic ulcer decreased with increasing age and was higher in men, patients aged < 30 years, and H. pylori-positive patients. The incidence of polyps was higher in women (9.54%) than in men (5.94%), and the incidence in individuals aged ≥60 years (11.63%) was higher than that in those aged < 60 years (6.83%). The pathological results of gastric polyps depended on the location of the lesion.

Conclusion

The incidence of abnormal upper gastrointestinal endoscopic results is high in asymptomatic healthy people undergoing a check-up and is associated with sex, age, and H. pylori infection. Gastroscopy should be considered part of a routine health check.
