Abstract
Purpose Esketamine have anesthetic and analgesic properties. This study aimed to observe the enhancing effect of subanesthetic doses of esketamine (0.15-0.3 mg/kg/h) with dexmedetomidine and remifentanil during anesthesia for liposuction surgery. Patients and Methods A total of 155 subjects were randomized with a 1:1 ratio to Group E (esketamine-dexmedetomidine/remifentanil, n=78) or Group C (saline-dexmedetomidine/remifentanil group, n=77). The primary outcome was satisfaction of patient and surgical team with the procedure. The secondary outcomes were the postoperative Athens Insomnia Scale (AIS) and Hospital Anxiety and Depression Scale (HADS) scores, hemodynamic and respiratory changes, drug consumption, adverse event rates, and predictors associated with patient satisfaction. Results Patient and surgical team satisfaction with the procedure was significantly higher in Group E than in Group C (4.7 ± 0.6 vs 4.2 ± 0.7, P < 0.001; 4.7 ± 0.5 vs 4.4 ± 0.7, P = 0.005). The postoperative AIS (4 [1, 6] vs 5 [2, 9], P = 0.012) and HADS-A (1 [0, 3] vs 2 [0, 6], P = 0.012) scores were significantly lower in Group E than in Group C. Hemodynamic and respiratory parameters were more stable in Group E than in Group C, with the lower opioids consumption of sufentanil (0 [0, 4] vs 5 [2.5, 7.7], P < 0.001) and remifentanil (700 [480, 900] vs 800 [500, 1200], P = 0.023) in Group E compared to Group C. On ordinal logistics regression, postoperative sleep quality (OR, 0.70; 95% CI, 0.62-0.79), anxiety level (OR, 0.77; 95% CI, 0.62-0.95) and recovery time in post-anesthesia care unit (PACU) (OR, 0.69; 95% CI, 0.56-0.98) were identified as significant predictors associated with patient satisfaction. Conclusion A subanesthetic dose of esketamine (0.15-0.3 mg/kg/h) as an adjuvant can improves the sedative and analgesic effects of dexmedetomidine and remifentanil during anesthesia for liposuction surgery.

Abstract
Background This study compared the efficacy of oropharyngeal airways (OA) and nasopharyngeal airways (NA) in maintaining oxygenation during painless fiberoptic bronchoscopy (PFB) in patients sedated with remimazolam besylate. Methods Two hundred and fifty-two patients were randomized to the OA or NA group. Remimazolam besylate was used for anesthesia induction and maintenance in both groups. We measured and recorded several physiological parameters, including mean arterial pressure, heart rate and oxygen saturation (SpO2), at various time points: before anesthesia (T1), after anesthesia induction (T2), immediately after the bronchoscope reached the trachea (T3), during the procedure (T4), and 5 min after transfer to the post-anesthesia care unit (T5). The incidence and frequency of hypoxemia, minimum SpO2 during the procedure and patient awakening time after flumazenil administration were also recorded. Additionally, the relationship between minimum SpO2 and body mass index (BMI) was investigated. Results Patients in the NA group experienced a higher incidence of hypoxemia compared to the OA group. Patients in the OA group maintained higher SpO2 levels at T3 and had a higher minimum SpO2 during the procedure than the NA group. Furthermore, a significant negative correlation was observed between minimum SpO2 and BMI. Following flumazenil anesthesia reversal, nearly 97 % of patients awakened within 1 min. Conclusions This study suggests that OA may provide a better safety profile than NA by preserving respiratory function during PFB.

Abstract
BACKGROUND Pulmonary Langerhans cell histiocytosis (PLCH) only with airway involvement manifested as diffuse thickening of the tracheobronchial walls is rare. CASE REPORT A 26-year-old male was admitted to the hospital with progressive wheezing, cough, and a source of blood in sputum after activity. He had no history of smoking. Chest computed tomography showed airway stenosis of different degrees with tracheobronchial wall thickening, and fiberoptic bronchoscopy demonstrated multiple nodular neoplasms in tracheobronchial, while the pulmonary parenchyma was normal. The patient's condition partially improved after excision of partial lesions by fiberoptic bronchoscope. Histopathological results showed that CD1a and S-100 immunohistochemical staining was positive, and the molecular pathological results suggested that the BRAF V600E mutation, thus confirming the diagnosis of PLCH. The treatment of partial resection and systemic chemotherapy is effective. CONCLUSIONS The possibility of PLCH needs to be considered when diffuse tracheobronchial lesions without lung parenchyma involvement are encountered, which provides experience for early clinical diagnosis and adequate treatment.

Abstract
BACKGROUND Ideal sedation and analgesia strategies for fiberoptic bronchoscopy have not been found. At present, propofol based sedation strategy still has some defects, such as respiratory depression and blood pressure drop. It is difficult to meet the requirements of safety and effectiveness at the same time. The aim of this study was to compare the clinical efficacy of propofol/remifentanil with propofol/esketamine for patient sedation during fiberoptic bronchoscopy. METHOD Patients undergoing fiberoptic bronchoscopy were randomly assigned to propofol/ remifentanil (PR group; n = 42) or propofol/esketamine (PK group; n = 42) for sedation and analgesia. The primary outcome was the rate of transient hypoxia (oxygen saturation (SpO2) < 95%). The secondary outcomes are the intraoperative hemodynamics, including the changes in blood pressure, heart rate, the incidence of adverse reactions, the total amount of propofol usage were recorded, and the satisfaction level of patients and bronchoscopists. RESULTS After sedation, the arterial pressure and heart rate of patients in the PK group were stable without significant decrease. Decreases in diastolic blood pressure, mean arterial pressure, and heart rate were observed in patients in the PR group (P < 0.05), although it was not of clinical relevance. The dosage of propofol in the PR group was significantly higher than that in the PK group (144 ± 38 mg vs. 125 ± 35 mg, P = 0.012). Patients in the PR group showed more transient hypoxia (SpO2 < 95%) during surgery (7 vs. 0, 0% versus 16.6%, P = 0.018), more intraoperative choking (28 vs. 7, P < 0.01), postoperative vomiting (22 vs. 13, P = 0.076) and vertigo (15 vs. 13, P = 0.003). Bronchoscopists in the PK group showed more satisfaction. CONCLUSION Compared with remifentanil, the combination of esketamine with propofol in fiberoptic bronchoscopy leaded to more stable intraoperative hemodynamics, lower dosage of propofol, lower transient hypoxia rate, fewer incidence of adverse events, and greater bronchoscopists satisfaction.

Front Pharmacol 2023; 14:1184663. [PMID: 37229247 PMCID: PMC10203403 DOI: 10.3389/fphar.2023.1184663] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Accepted: 04/20/2023] [Indexed: 05/27/2023] Open
Abstract
Background: Flexible fiberoptic bronchoscopy (FFB) for children is widely performed under sedation. Currently, the optimal sedation regimen remains unclear. Esketamine is an N-methyl-D-aspartic acid (NMDA) receptor antagonist, which has stronger sedative and analgesic effects and exerts less cardiorespiratory depression than other sedatives. The purpose of this study was to evaluate whether a subanesthetic dose of esketamine as an adjuvant to propofol/remifentanil and spontaneous ventilation compared with control reduces the procedural and anesthesia-related complications of FFB in children. Materials and methods: Seventy-two children ≤ 12 years of age who were scheduled for FFB were randomly assigned, in a 1:1 ratio, to the esketamine-propofol/remifentanil (Group S, n = 36) or to the propofol/remifentanil group (Group C, n = 36). All children were retained spontaneous ventilation. The primary outcome was the incidence of oxygen desaturation (respiratory depression). Perioperative hemodynamic variables, blood oxygen saturation (SPO2), end-tidal partial pressure of carbon dioxide (PetCO2), respiratory rate (R), and the Bispectral index (BIS), induction time, procedural time, recovery time, the time to the ward from the recovery room, consumption of propofol and remifentanil during the procedure and the appearance of adverse events, including paradoxical agitation following midazolam administration, injection pain, laryngospasm, bronchospasm, PONV, vertigo, and hallucination were also compared. Results: The incidence of oxygen desaturation was significantly lower in Group S (8.3%) compared to Group C (36.1%, p = 0.005). The perioperative hemodynamic profile including SBP, DBP, and HR were more stable in Group S than that in Group C (p < 0.05). Consumption of propofol and remifentanil was lower in Group S than in Group C (p < 0.05). Furthermore, PAED scores, cough scores and injection pain were lower in the Group S than in Group C (p < 0.05). The recovery time of Group S was slightly longer than that of Group C (p < 0.05). Nobody happened paradoxical agitation following midazolam administration, PONV, vertigo, and hallucinations in both groups (p > 0.05). Conclusion: Our findings indicate that a subanesthetic dose of esketamine as an adjuvant to propofol/remifentanil and spontaneous respiration is an effective regimen for children undergoing FFB. Our findings will provide a reference for clinical sedation practice during these procedures in children.

Efficacy and safety of ciprofol-remifentanil versus propofol-remifentanil during fiberoptic bronchoscopy: A prospective, randomized, double-blind, non-inferiority trial. Front Pharmacol 2022; 13:1091579. [PMID: 36618929 PMCID: PMC9812563 DOI: 10.3389/fphar.2022.1091579] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 12/07/2022] [Indexed: 12/24/2022] Open
Abstract
Objective: Ciprofol is a novel 2,6-disubstituted phenol derivative that has improved pharmacokinetic and pharmacodynamic properties compared with propofol. This study was conducted to compare the efficacy and safety of ciprofol-remifentanil versus propofol-remifentanil for patients undergoing fiberoptic bronchoscopy. Methods: Overall, 92 patients undergoing fiberoptic bronchoscopy were included in this prospective, randomized, double-blind, non-inferiority trial and were equally divided into two groups (n = 46 each). Fentanyl (50 μg) was given 2 min before the intravenous infusion of 0.3 mg/kg of ciprofol or 1.2 mg/kg of propofol over a time period of 30 s. During anesthesia maintenance, 0.05-0.2 μg/kg/min of remifentanil combined with one-third to one-fourth of the initial dose of ciprofol or propofol was repeated at 2-min intervals, as required, to maintain a Modified Observer's Assessment of Alertness and Sedation (MOAA/S) scale score <3. The primary outcome was the successful rate of fiberoptic bronchoscopy. Secondary outcomes included demographic characteristics, time metrics, hemodynamics, coughing severity, intubating conditions, lowest oxygen saturation, utilization of study drug doses, number of remedies (lidocaine and vasoactive drugs) used, satisfaction scores of both patients and the endoscopist, occurrence of intraoperative awareness, patients' willing to repeat fiberoptic bronchoscopy, and occurrence and severity of adverse events. Results: The successful completion rate of fiberoptic bronchoscopy was 91.30% (42 of 46; 95% confidence interval [CI]: 82.80%-99.80%) in the ciprofol-remifentanil group and 89.13% (41 of 46; 95% CI: 79.80%-98.50%) in the propofol-remifentanil group. Though the clinically acceptable intubating condition was improved in the ciprofol-remifentanil group, this difference has no clinical statistical difference (p > 0.05). No significant differences were noted between the two groups with respect to time metrics, consumption of fentanyl and remifentanil, or number of remedies (lidocaine and vasoactive drugs). Patients' willingness to repeat fiberoptic bronchoscopy and the satisfaction of both patients and endoscopist were significantly higher in the ciprofol-remifentanil than in the propofol-remifentanil group (p < 0.05). Compared with patients in the propofol-remifentanil group, patients in the ciprofol-remifentanil group had more stable hemodynamics. The lowest oxygen saturation was significantly higher in the ciprofol-remifentanil than in the propofol-remifentanil group (p < 0.05). The numbers of patients who experienced pain on injection in the ciprofol-remifentanil group was significantly lower than the number in the propofol-remifentanil group (p < 0.01). Severity of coughing, clinically acceptable severity of coughing, incidence of intraoperative awareness, and other adverse events were all similar between the two groups (p > 0.05). Only four patients experienced grade 2 adverse events (severe hypotension in one patient in the ciprofol-remifentanil group and three patients in the propofol-remifentanil group; p > 0.05); they were treated with noradrenaline. Conclusion: Ciprofol-remifentanil was non-inferior to propofol-remifentanil with regard to successful sedation for flexible bronchoscopy, when used with pre-intravenous administration of 50 μg of fentanyl. At the same time, patients' willingness to repeat flexible bronchoscopy and the satisfactions were all significantly improved.

Abstract
Objective This study aimed to determine the effective concentration of target-controlled infusion (TCI) of remifentanil used to inhibit stress during the treatment of severe tracheal stenosis with fibreoptic bronchoscopy and to evaluate the monitored anesthesia care (MAC) by remifentanil. Materials and methods 60 patients with severe tracheal stenosis who underwent fibreoptic bronchoscopy was performed. Dexmedetomidine was initially administered at a bolus dose (0.8 mcg/kg), followed by a 0.5 mcg/(kg⋅h) continuous infusion. Remifentanil was administered by TCI. The effective concentration (EC) of remifentanil was titrated by the improved sequential method, and 30 patients were included. The EC95 of remifentanil was set as the plasma target concentration to evaluate the safety of the MAC, and another 30 patients were included. Results The half effective effect-chamber concentration of remifentanil (EC50) was 2.243 ng/ml, and the EC95 was 2.710 ng/ml. Among the 30 patients who received an EC95 of remifentanil as the target concentration, one patient was remedied by injecting propofol, the score of Ramsay sedation was three. The incidence of subclinical hypoxemia (SPO2 of 90-95%) was 30%, the incidence of moderate hypoxemia (SPO2 of 75-89%, ≤60 s) was 20 and 86.7% of patients with oxygen saturation was less than 95% returned to normal by awakening. The satisfaction score of the operator was nine, the satisfaction score of the anesthesiologist was eight, the satisfaction score of the patients was 10, the rate of patient willingness to re-accept the procedure was 93.3% and the circulation was stable during the operation. Conclusion MAC using TCI of remifentanil with continuous pumping dexmedetomidine can effectively inhibit the stress response to fibreoptic bronchoscopy in patients with severe tracheal stenosis while maintaining spontaneous breathing. Under the anesthesia management of an experienced anesthesiologist, it provides a reference to tracheoscopic anesthesia of autonomous breathing.

Abstract
INTRODUCTION The use of monitored anaesthesia care (MAC) is necessary and ubiquitous for fiberoptic bronchoscopy. Anaesthetic management of patients with severe tracheal stenosis has always been a challenge. The efficacy and safety of the MAC with sufentanil target controlled infusion (TCI) and remifentanil TCI in patients with severe tracheal stenosis are still unknown. METHODS ANALYSIS This study is a prospective, investigator-initiated, two-arm, randomised control trial to compare the efficacy and safety of sufentanil TCI with remifentanil TCI in patients with severe tracheal stenosis undergoing fiberoptic bronchoscopy. 270 patients will be randomly assigned to the sufentanil TCI group or remifentanil TCI group, with a 1:1 ratio in two groups. The primary outcome is the incidence of hypoxaemia (an oxygen saturation of <90%). The secondary outcome investigates the severity of hypoxaemia, cough severity, haemodynamic variables, sedation scores and satisfaction scores. ETHICS AND DISSEMINATION The study has been approved by the Medical Ethics Committee of Shanghai Pulmonary Hospital (approval No. K19-122). The results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER ChiCTR2100043380.

The Efficacy and Safety of Remimazolam Tosilate Versus Dexmedetomidine in Outpatients Undergoing Flexible Bronchoscopy: A Prospective, Randomized, Blind, Non-Inferiority Trial. Front Pharmacol 2022; 13:902065. [PMID: 35721180 PMCID: PMC9201326 DOI: 10.3389/fphar.2022.902065] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 05/04/2022] [Indexed: 12/16/2022] Open
Abstract
Purpose: This study aimed to compare the efficacy and safety of remimazolam tosilate-remifentanil (RT-RF) vs dexmedetomidine-remifentanil (Dex-RF) for outpatients undergoing fiberoptic bronchoscopy (FB). Patients and methods: We conducted a double-blind, randomized, prospective study involving a total of 146 outpatients undergoing FB divided into two groups. The RT-RF (RR) group (n = 73) received an initial dose of 12 mg/kg/h of RT for 10 min followed by a maintenance dose of 1–2 mg/kg/h, while the Dex-RF (DR) group (n = 73) received an initial dose of 0.5 μg/kg of Dex for 10 min followed by a maintenance dose of 0.2–0.7 μg/kg/h. All outpatients also received 0.05–0.2 μg/kg/min RF to maintain the Modified Observer’s Assessment of Alertness and Sedation (MOAA/S) scale <3. The primary outcome was rate of successful FB completed. Secondary outcomes were time metrics, hemodynamics, intubating conditions, oxygen saturation, coughing severity, number of remedies, total dose of fentanyl, RF, RT, and Dex, incidence of dreaming, patient and bronchoscopist satisfaction, willingness to repeat bronchoscopy, and adverse events. Results: The FB successful completion rate was 94.52% (95% CI: 89.20–99.90) in the RR group and 91.78% (95% CI: 85.30–98.20) in the DR group. Compared with patients in the DR group, the onset time, time to fully alert, and hospital discharge were all significantly shorter in the RR group (p < 0.01), and hemodynamics were more stable in the RR group. Intubating conditions, clinically acceptable intubating conditions, lowest oxygen saturation, coughing severity, consumption of fentanyl and RF, number of remedies, and patient and bronchoscopist satisfaction were similar between the groups (p > 0.05), as were demographic characteristics, incidence of dreaming, willingness to repeat bronchoscopy, and adverse events (p > 0.05). Conclusion: RT-RF has non-inferior efficacy, better time metrics and hemodynamic stability for outpatients undergoing FB than Dex-RF.

Abstract
Foreign body aspiration can produce a medical emergency. Obstruction of the airways can be life-threatening, and complications may develop in less-severe cases if it is left untreated. Although it is more prevalent in children by approximately three times, adults can still experience it, and it is more frequently related to healthcare in adults. Objects used in dental treatment are usually placed in the oral cavity and can be ingested or inhaled by accident. Dental treatment has been identified as an important cause of the misplacement of foreign bodies in the airway. However, few reports have been published on dentistry-related foreign body aspiration. This paper discusses the disease course, management, and clinical outcomes of foreign body aspiration, especially those associated with dentistry. The patient must be examined for respiratory distress. If the patient is unstable, urgent airway management and the maneuvers for removal should be performed. Radiographs and computed tomography can help identify and locate the object. The treatment of choice is often bronchoscopy, and both flexible and rigid endoscopes can be used depending on the situation. Preventive measures need to be implemented to avoid inhalation accidents given the potential consequences. Though the incidence is rare, healthcare levels need to be enhanced to avert morbidity and mortality. Radiological evaluation and bronchoscopy are vital for management.

Abstract
OBJECTIVE To investigate the necessity, safety and feasibility of painless fiberoptic bronchoscopy in patients with coronavirus disease 2019 (COVID-19). OBJECTIVE We retrospectively analyzed the clinical characteristics of 33 patients diagnosed with COVID-19 who received painless fiberoptic bronchoscopy in Wuhan First Hospital. The general demographic and clinical data of the patients including age, gender, and ASA classification were collected. The patients received intravenous anesthesia with topical airway anesthesia with lidocaine. The changes in the vital signs of the patients were recorded before, during and after the procedure. The cough intensity of the patients during bronchoscopy were evaluated, and the adverse reactions within 24 h after the procedure were observed. The health status of the medical staff carrying out the procedure was also monitored. OBJECTIVE The 33 patients with ASA class Ⅱ to Ⅳ included 19 male and 14 female patients with an average age of 63.58±11.85 years. The lowest SpO2 of the patients during bronchoscopy was (94.8±4.3)%, which was significantly lower than that before the procedure [(99.1±1.3)%, P < 0.05] but was restored to more than 95% after such treatment as holding the jaw to open the airway or face mask positive-pressure ventilation. Bronchoscopy was completed successfully in all the patients, and 28 patients (84.85%) had mild cough during the procedure. None of the patients had obvious complications related to anesthesia. While performing the procedure, all the medical staff used third-level protection and facial protection with powered air-purifying respirators (PAPR), and the patients' face were covered with single-use sterile medical plastic curtains that were originally intended for collecting flushing fluid during arthroscopic procedures. No medical personnel was diagnosed with COVID-19 at the end of the study. OBJECTIVE For patients with COVID-19, painless techniques can be valuable during bronchoscopy, and this procedure can be safe and feasible under third-level protection.

[PMID: 33336889 DOI: 10.1002/ppul.25235] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 12/03/2020] [Accepted: 12/15/2020] [Indexed: 01/06/2023]
Abstract
INTRODUCTION In pediatric patients, flexible bronchoscopy requires deep sedation. Different sedation regimes are common, but only some of them include opioids. Due to their antitussive effect, the use of short-acting opioids may be beneficial for this particular indication, but additional respiratory depression may lead to an increase in adverse events. Here, we systematically compared sedation regimes in children undergoing flexible bronchoscopy with either propofol alone, or a combination of propofol and remifentanil. The primary outcome parameter was the frequency of coughing episodes during the intervention. Secondary outcome parameters were frequency and types of complications, patient satisfaction, examiner satisfaction, and recovery time after finishing the sedation. METHODS Fifty children aged 1-17 years undergoing flexible bronchoscopy under deep sedation with propofol were randomly assigned to two groups: PR receiving propofol and remifentanil and PP receiving propofol only. Sedation depth was predefined as Comfort Score 10-13. RESULTS We found significantly less coughing episodes ([med (IQR)] PR: 0.73 (0.28-2.45)/min; PP: 1.98 (1.26-3.12)/min; p = .010) and shorter recovery time in Group PR (PR: 13.5 (8-17.5) min; PP: 21.0 (14-27) min; p = .011). Examiner's satisfaction was higher in Group PR (PR: 10 (8-10); PP: 9 (7-9); p = .012). The number of adverse events, patient satisfaction, and required propofol dose during the intervention did not differ between groups. CONCLUSION We suggest the combination of propofol with remifentanil instead of using propofol alone in pediatric procedural sedation for flexible bronchoscopy.
