Abstract
Background The effectiveness of using a spray nozzle to deliver lidocaine for superior topical airway anaesthesia during non-sedation flexible bronchoscopy (FB) remains a topic of uncertainty when compared with conventional methods. Methods Patients referred for FB were randomly assigned to receive topical lidocaine anaesthesia via the bronchoscope's working channel (classical spray (CS) group) or through a washing pipe equipped with a spray nozzle (SN group). The primary outcome was cough rate, defined as the total number of coughs per minute. Secondary outcomes included subjective perceptions of both the patient and operator regarding the FB process. These perceptions were rated on a visual analogue scale, with numerical ratings ranging from 0 to 10. Results Our study enrolled a total of 126 (61 CS group; 65 SN group) patients. The SN group exhibited a significantly lower median cough rate compared with the CS group (4.5 versus 7.1 counts·min-1; p=0.021). Patients in the SN group also reported less oropharyngeal discomfort (4.5±2.7 versus 5.6±2.9; p=0.039), better tolerance of the procedure (6.8±2.2 versus 5.7±2.7; p=0.011) and a greater willingness to undergo a repeat FB procedure (7.2±2.7 versus 5.8±3.4; p=0.015) compared with those in the CS group. From the operator's perspective, patient discomfort (2.7±1.7 versus 3.4±2.3; p=0.040) and cough scores (2.3±1.5 versus 3.2±2.4; p=0.013) were lower in the SN group compared with the CS group, with less disruption due to coughing observed among those in the SN group (1.6±1.4 versus 2.3±2.3; p=0.029). Conclusions This study illustrates that employing a spray nozzle for the delivery of lidocaine provides superior topical airway anaesthesia during non-sedation FB compared with the traditional method.

Abstract
BACKGROUND Remimazolam is a new benzodiazepine used for procedural sedation and general anesthesia. Several studies have used remimazolam for bendable bronchoscopy. AIM To assess the safety and efficacy of remimazolam for sedation in patients undergoing bendable bronchoscopy by performing a meta-analysis of randomized controlled trials (RCTs). METHODS We searched the EMBASE, PubMed, Cochrane Library, and Web of Science databases for RCTs on bendable bronchoscopic procedural sedation with remimazolam vs conventional sedatives (CS). RESULTS Five studies with 1080 cases were included. Remimazolam had the same sedation success rate compared with CS [relative risk (RR): 1.35, 95%CI: 0.60-3.05, P = 0.474, I2 = 99.6%]. However, remimazolam was associated with a lower incidence of hypotension (RR: 0.61; 95%CI: 0.40-0.95, P = 0.027; I2 = 65.1%) and a lower incidence of respiratory depression (RR: 0.50, 95%CI: 0.33-0.77, P = 0.002, I2 = 42.3%). A subgroup analysis showed a higher success rate of sedation with remimazolam than midazolam (RR: 2.45, 95%CI: 1.76-3.42, P < 0.001). Compared with propofol, the incidence of hypotension (RR: 0.45, 95%CI: 0.32-0.64, P < 0.001, I2 = 0.0%), respiratory depression (RR: 0.48, 95%CI: 0.30-0.76, P = 0.002, I2 = 78.4%), hypoxemia (RR: 0.36, 95%CI: 0.15-0.87, P = 0.023), and injection pain (RR: 0.04, 95%CI: 0.01-0.28, P = 0.001) were lower. CONCLUSION Remimazolam is safe and effective during bronchoscopy. The sedation success rate was similar to that in the CS group. However, remimazolam has a higher safety profile, with fewer inhibitory effects on respiration and circulation.

Abstract
OBJECTIVE To evaluate the efficacy and safety of a hospital-made resuscitation pack, a Chinese medicinal herbal compound formula designed to enhance recovery in post-bronchoscopy patients. METHODS In this randomized, single-blind, placebo-controlled clinical trial, eligible patients were randomly assigned 1:1 to either the treatment or control groups. The patients in the treatment group applied the resuscitation pack, which contained aromatic compounded Chinese herbs. The patients in the control group applied a hospital-made, single herb placebo pack. Packs were placed on the Tiantu (CV 22) acupuncture point for 4 h as soon as the bronchoscopy finished. Efficacy indicators, such as recovery time, patients' symptoms including nausea and dizziness, and adverse events (AEs) were observed and compared. The outcome indices were evaluated at baseline, 1 and 24 h after the bronchoscopy. Subgroup analysis was further performed by patients' age and depth of sedation. RESULTS When applying generalized estimating equations (GEE) to evaluate the intensity of post-bronchoscopy nausea and vomiting, the intensity was lower in the treatment group (163 cases) compared with the control group (162 cases; 95% CI: 0.004, 0.099, P=0.03]. Also, significantly lower intensity of nausea was observed in the 60-70 years of age subgroup (95% CI: 0.029, 0.169, P=0.006) and deep sedation subgroup (95% CI: 0.002, 0.124; P=0.04). There was no significant difference in dizziness between two groups by GEE (95% CI: -0.134, 0.297; P=0.459). In addition, no serious AEs were observed in either group. CONCLUSIONS Our study found that the resuscitation pack markedly improved patients' symptoms by reducing nausea and vomiting after bronchoscopy without AEs, compared with placebo in the perioperative period.

Abstract
Background Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an invasive procedure that required deep sedation to suppress coughing and body movements. Deep sedation, on the other hand, has been shown to cause respiratory and circulatory depression, especially when the airway is shared with the endoscopist. Esketamine is a novel sedative and analgesic with little respiratory inhibition that appears to be an appropriate adjuvant in propofol sedation for EBUS-TBNA. We compared the efficacy and safety of esketamine combined with propofol target-controlled infusion (TCI) and propofol TCI for deep sedation in EBUS-TBNA. Methods The study included 135 patients with ASA II-III undergoing EBUS-TBNA. They were randomly divided into two groups (group E and group P). Both groups received midazolam (0.01-0.03 mg/kg) and oxycodone (0.07-0.08 mg/kg). Then, patients in group E received 0.3 mg/kg esketamine, propofol TCI, and 0.2 mg·kg-1·h-1 esketamine for sedative maintenance. Patients in group P received only propofol TCI. The primary outcome was the dose of 1% lidocaine administrated by the endoscopist and the times of lidocaine sprays. Secondary outcome indicators were cough score, propofol dosage, patient satisfaction, endoscopist satisfaction, the incidence of sedation-related adverse effects and side effects, and recovery time. Results Patients in group E were given significantly less lidocaine (4.36 ml/h (2.67-6.00) vs 6.00 ml/h (4.36-7.20), P < 0.001) and less spraying frequency (2.18 times/h (1.33-3.00) vs 3.00 times/h (2.18-3.60), P < 0.001) than group P. There was a statistically significant difference in cough score between the two groups (group E 2 (0-4) vs group P 3 (2-4), P=0.03). Also, mean arterial pressure (MAP) was higher in group E in the 30th min (T5, 84.10 ± 12.91 mmHg versus 79.04 ± 10.01 mmHg, P=0.012) and 40th min (T6, 87.72 ± 15.55 mmHg versus 82.14 ± 10.51 mmHg, P=0.026). There were no significant differences between the two groups in terms of sedation-related adverse events and side effects, recovery time, endoscopist satisfaction, and patient satisfaction. Conclusions In patients with ASA II-III, esketamine as an adjuvant in combination with propofol TCI deep sedation for EBUS-TBNA can improve the sedation effect, reduce coughing reaction during the procedure, and obtain more stable blood pressure. No reduction in the occurrence of sedation-related side effects was observed. This trial is registered with ChiCTR2200061124.

Abstract
Although remimazolam is an ultra-short-acting benzodiazepine with a shorter elimination half-life and faster recovery time than midazolam, studies evaluating its safety and efficacy during bronchoscopy are limited. This study aimed to compare the safety and efficacy of remimazolam with those of midazolam for bronchoscopy. This prospective randomized parallel-group study was conducted at a single institution. The primary outcome was the time from the end of the procedure to full alertness. Other procedural time parameters, satisfaction profiles, and adverse effects were thoroughly evaluated. The time taken to reach peak sedation and the time from the end of the procedure to full alertness was significantly shorter in the remimazolam group than in the midazolam group (median [interquartile range], 2 min [1-4] vs. 3 min [2-5], P = 0.006; and median, 2 min [1-5] vs. 5 min [1-12], P = 0.035, respectively). In patients with non-biopsy procedures (n = 79), participant satisfaction was significantly higher in the remimazolam group than in the midazolam group (median rated scale, 10 vs. 7, P = 0.042). Physician satisfaction and willingness to repeat the procedure were similar between groups. Although the incidence of adverse effects was similar between the groups and there was no significant difference, the midazolam group had a higher antidote administration rate than the remimazolam group (15.7% vs. 4.1%, P = 0.092). Remimazolam is effective and safe for achieving adequate sedation, with a shorter onset time and faster neuropsychiatric recovery than midazolam. It may be a new option for sedation during bronchoscopy.Trial registration: The trial registration number is NCT05994547, and the date of first registration is 16/08/2023.

Abstract
BACKGROUND We sometimes experience disinhibition during bronchoscopy with sedation. However, the impact of adding pethidine on disinhibition has not yet been investigated. This study aimed to examine the additive impact of pethidine on disinhibition during bronchoscopy with midazolam. METHODS This retrospective study involved consecutive patients who underwent bronchoscopy between November 2019 and December 2020 (sedated with midazolam: Midazolam group) and between December 2020 and December 2021 (sedated with midazolam plus pethidine: Combination group). The severity of disinhibition was defined as follows: moderate, disinhibition that always needed restraints by assistants; and severe, disinhibition that needed antagonization of sedation by flumazenil to continue bronchoscopy. One-to-one propensity score matching was used to match baseline characteristics between both groups. RESULTS After propensity score matching with depression, the type of bronchoscopic procedure, and the dose of midazolam, 142 patients matched in each group. The prevalence of moderate-to-severe disinhibition significantly decreased from 16.2% to 7.8% (P = 0.028) in the Combination group. The Combination group had significantly better scores for sensation after bronchoscopy and feelings toward bronchoscopy duration than did the Midazolam group. Although the minimum SpO2 during bronchoscopy was significantly lower (88.0 ± 6.2 mmHg vs. 86.7 ± 5.0 mmHg, P = 0.047) and the percentage of oxygen supplementation significantly increased (71.1% vs. 86.6%, P = 0.001) in the Combination group, no fatal complications were observed. CONCLUSIONS Adding pethidine could reduce disinhibition occurrence in patients undergoing bronchoscopy with midazolam, with better subjective patient outcomes during and after bronchoscopy. However, whether more patients may need oxygen supplementation and whether hypoxia occurs during bronchoscopy should be considered. CLINICAL TRIAL REGISTRATION UMIN000042635.

Abstract
(1) Background: Anesthetic sedatives are widely used for bronchoscopy, and controversy surrounds the safety and efficacy of dexmedetomidine compared to other sedatives. The aim of this study is to evaluate the safety and efficacy of dexmedetomidine in bronchoscopy through a systematic review. (2) Methods: PubMed, Embase, Google Scholar, and Cochrane Library electronic databases were searched for a randomized controlled study of dexmedetomidine (Group D) or other sedative drugs (Group C) for bronchoscopy. Data extraction, quality assessment, and risk of bias analysis were performed in accordance with the preferred reporting items for systematic review and meta-analysis requirements. Meta-analysis was performed using RevMan 5.2. (3) Results: Nine studies were included, with a total of 765 cases. Compared to Group C, the incidence of hypoxemia (OR = 0.40, 95% CI (0.25, 0.64) p = 0.0001, I2 = 8%) and tachycardia (OR = 0.44, 95% CI (0.26,0.74), p = 0.002, I2 = 14%) were lower, but bradycardia (OR = 3.71, 95% CI (1.84, 7.47), p = 0.0002, I2 = 0%) was higher in Group D; no significant difference was observed in other outcome indicators. (4) Conclusions: Dexmedetomidine reduces the incidence of hypoxemia and tachycardia during bronchoscopy but is more likely to provoke bradycardia.

Abstract
We explored whether a combination of an opioid (fentanyl or pethidine) and midazolam could safely sedate Japanese patients undergoing bronchoscopic procedures. We searched the PubMed Medline and Igaku Chuo Zasshi (ICHUSHI) databases from 1980 to 2022 for papers on sedatives used during bronchoscopy, especially opioids (fentanyl and pethidine) and midazolam. The keywords were "bronchoscopy" and "sedation" ("kikanshikyo" and "chinsei", respectively, in Japanese). The results showed that midazolam was the preferred sedation agent during flexible bronchoscopy; with midazolam sedation is rapid, and the drug is associated with anterograde amnesia and decreased discomfort. A combination of an opioid (fentanyl or pethidine) and midazolam improved the patient tolerance and willingness to undergo a repeat procedure and also improved the working conditions for the physician. The British Thoracic Society guideline of 2013 suggested that a combination of an opioid (fentanyl or alfentanil) and midazolam should be considered to improve bronchoscopic tolerance. The American College of Chest Physicians Consensus Statement of 2011 suggested that fentanyl should be preferred; the onset of action and peak effect are rapid, and the effects are of relatively short duration. Emphasis has been placed on safety aspects, such as patient monitoring, the precautions that should be taken in patients with certain conditions, prevention and management of complications, adequate staffing, and optimal sedation and disinfection. In conclusion a combined opioid (fentanyl or pethidine) and midazolam sedation is optimal for diagnostic and therapeutic flexible bronchoscopy in Japanese patients.

Abstract
BACKGROUND The desired depth of sedation during flexible bronchoscopy is one in which verbal contact is possible whenever necessary. Although it is common that the depth of sedation is assessed by validated instruments such as the modified observer's assessment of alertness and sedation (MOAA/S) score, the repeated stimulation associated with the assessment can affect the sedation. The bispectral index (BIS) has been widely used for general anesthesia due to its objective and noninvasive nature. However, the utility of BIS monitoring and a target BIS value for use during bronchoscopy have not been fully elucidated. METHODS We performed a retrospective observational study to assess the utility of the BIS value for monitoring conscious sedation during bronchoscopy at Kobe University Hospital from August 2020 to April 2021. RESULTS Eighteen patients underwent bronchoscopy with BIS monitoring. The BIS value significantly correlated with the MOAA/S score (r = 0.2, p < 0.01), and the correlation was stronger in sufficiently sedated patients (r = 0.486, p < 0.01). The lowest MOAA/S score during the procedure was highly correlated with the BIS value (r = 0.625, p < 0.01). The BIS monitoring seemed to be more sensitive to changes in the sedation level than the MOAA/S score, heart rate and mean arterial pressure. The median BIS value at an MOAA/S score of 3-4, the desired depth of sedation, was 82.0. CONCLUSIONS BIS value is useful for monitoring sedation during bronchoscopy. This study suggests that a BIS value of 82 reflects an adequate level of sedation.

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
Endobronchial ablative therapy (EAT) in patients with preexisting obstructive airway disease can cause hypoxemia because bronchoscope insertion interferes with ventilation and a low fraction of inspired oxygen (FiO2) is essential to avoid airway fire. A man in his early 50s with moderately severe obstructive airway disease was scheduled for EAT for treatment of tracheal papillomatosis. Ventilation and oxygenation would have been difficult because of narrowing of the endotracheal tube by bronchoscopic insertion and a low FiO2; therefore, an i-gel supraglottic airway device with a larger inner diameter was inserted. All visible intratracheal papillomas were ablated by a potassium titanyl phosphate laser through the bronchoscopic port that passed through the lumen of the i-gel at an FiO2 of 0.3. During anesthesia for EAT, the i-gel supraglottic airway device provided a wider lumen for ventilation. We were thus able to provide stable ventilation at an FiO2 of 0.3 during EAT in this patient with obstructive airway disease, avoiding airway fire and hypoxemia.

Abstract
BACKGROUND Flexible bronchoscopy is an aerosol-generating procedure (AGP), which increases the risk of transmission of SARS-CoV-2 infection. We aimed to find COVID-19 symptoms among healthcare workers (HCWs) involved in flexible bronchoscopies for non-COVID-19 indications during the SARS-CoV-2 pandemic. MATERIALS AND METHODS The participants of this hospital-based single-center descriptive study were HCWs of our hospital involved in flexible bronchoscopies of patients with non-COVID-19 indications. These patients had no clinical features of COVID-19 and were tested negative for SARS-CoV-2 by the real-time polymerase chain reaction of nasopharyngeal and throat swabs before the procedure. The study outcome was the occurrence of COVID-19 in study participants after exposure to bronchoscopies. RESULTS Thirteen HCWs performed 81 bronchoscopies on 62 patients. Indications for bronchoscopies included malignancy (61.30%), suspected infections (19.35%), non-resolving pneumonia (6.45%), mucus plug removal (6.45%), central airway obstruction (4.84%), and hemoptysis (1.61%). The mean age of patients was 50.44 ± 15.00 years, and the majority was males (72.58%). Bronchoscopic procedures included 51 bronchoalveolar lavages, 32 endobronchial ultrasound- transbronchial needle aspiration (EBUS-TBNA), 26 endobronchial biopsies, 10 transbronchial lung biopsy (TBLB), 3 mucus plug removals, 2 conventional TBNA, and 2 radial EBUS-TBLB. Except for two HCWs who complained of transient throat irritation of non-infectious cause, none of the cases developed any clinical features suggestive of COVID-19. CONCLUSION A dedicated bronchoscopy protocol helps in minimizing the risk of transmission of SARS-CoV-2 infection among HCWs involved in flexible bronchoscopies for non-COVID-19 indications during the SARS-CoV-2 pandemic.

Abstract
BACKGROUND Fiberoptic bronchoscopy is a complex procedure with the need for sufficient patient anesthesia/sedation while maintaining safety. This trial aimed to evaluate the efficacy, safety, and pharmacokinetics of HSK3486 during fiberoptic bronchoscopy. METHODS This multicenter, double-blind, randomized, non-inferiority, parallel-group phase 3 trial was conducted in patients who underwent fiberoptic bronchoscopy. Patients randomly received HSK3486 0.4 mg/kg (N = 134) or propofol 2.0 mg/kg (N = 133). The primary efficacy endpoint was the successful rate of fiberoptic bronchoscopy, and secondary efficacy endpoints included successful induction of anesthesia/sedation, duration, time to being fully alert, and time to patient discharge. Safety assessments and drug concentrations were also measured. RESULTS A total of 267 patients completed fiberoptic bronchoscopy, with a success rate of 100% and a 95% confidence interval of - 2.8 to 2.8% for the difference between the groups, which met the predesigned criteria of > - 8%, confirming the non-inferiority of anesthesia/sedation produced by HSK3486 compared to propofol. Among the secondary efficacy endpoints, only time to full alertness (median 8.50 vs. 6.00 min, P = 0.012) and time to discharge (median 13.00 vs. 9.87 min, P = 0.002) were slightly longer in the HSK3486 group. The incidence of adverse events was significant lower in the HSK3486 group (52.6 vs. 76.5%, P < 0.001) mainly because of less pain on injection (4.4 vs. 39.4%, P < 0.001) compared to the propofol group. HSK3486 had a similar terminal elimination half-life as propofol. CONCLUSIONS HSK3486 exhibited non-inferiority anesthesia/sedation compared to propofol in patients undergoing fiberoptic bronchoscopy, and had a good safety profile with a lower incidence of pain on injection.

Abstract
BACKGROUND With complex, lengthy bronchoscopies, there is a need for safe, effective sedation. Most bronchoscopists strive for moderate sedation, though often difficult without compromising vital signs. The Modified Observer's Assessment of Alertness and Sedation (MOAA/S) scale is a validated 6-point scale assessing responsiveness of patients coinciding with the American Society of Anesthesiologists (ASA) continuum of sedation. It is commonly used in studying bronchoscopic sedation, but depth of sedation by MOAA/S and correlation with vital signs and adverse events has not been determined. METHODS This study was a post hoc analysis of a prospective, double-blind, randomized trial evaluating the safety and efficacy of remimazolam. MOAA/S and corresponding vital signs were used to assess the effect of the level of sedation on vital signs and adverse events. RESULTS A total of 23,341 MOAA/S scores from 431 patients were recorded. Older and higher ASA class patients spent more time in deeper sedation (MOAA/S 0 to 1) (6% vs. 2%, P=0.01). Oxygen saturation was equal in deep sedation (MOAA/S 0 to 1) (97±3%) compared with moderate sedation (96±3%) (P=0.11). Mean systolic and diastolic blood pressures were significantly lower when comparing MOAA/S 0 to 1 to MOAA/S 5 (systolic blood pressure: 126±19 vs. 147±24 mm Hg, P<0.01; diastolic blood pressure: 68±14 vs. 84±15 mm Hg, P<0.01). There was a nonsignificant trend towards lower heart rate at deep versus moderate sedation (84±15 vs. 94±18 beats/min, P=0.07). Respiratory rate was also comparable with moderate and deep sedation (17±5 vs. 18±6 beats/min, P=0.94). CONCLUSION There was no clinically meaningful correlation between vital signs and depth of sedation assessed by MOAA/S. Older and higher ASA class patients spend more time in deeper sedation. However, when in deep sedation, there was no difference in vital signs other than a slightly increased incidence of clinically insignificant hypotension.

Abstract
BACKGROUND Disinhibition is sometimes experienced during bronchoscopy with sedation. However, data on disinhibition during bronchoscopy are scarce. We examined the prevalence and characteristics of disinhibition during bronchoscopy with midazolam. METHODS This retrospective study analyzed consecutive patients who underwent bronchoscopy between November 2019 and December 2020. The severity of disinhibition was defined as follows: mild, disinhibition sometimes requiring restraints by assistants; moderate, disinhibition always requiring restraints by assistants; and severe, disinhibition requiring antagonization of sedation by flumazenil to continue bronchoscopy. RESULTS Among 251 eligible patients who were sedated using midazolam, 36 (14.3%; 95% confidence interval [CI], 10.5%-19.2%), 42 (16.7%; 95% CI, 12.6%-21.8%), and 7 (2.8%; 95% CI, 1.4%-5.6%) experienced mild, moderate, and severe disinhibition, respectively. Depression (odds ratio [OR] 2.77; 95% CI, 1.20-6.41), endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) (OR 10.23; 95% CI, 1.02-103.01, referred to brushing/bronchial washing/observation), and increased administration of midazolam (OR 1.20; 95% CI, 1.02-1.42, per 1-mg increase) were independently associated with moderate-to-severe disinhibition. Patients experiencing moderate disinhibition reported significantly better scores for discomfort during bronchoscopy. Besides the maximum systolic and diastolic blood pressures during bronchoscopy, the changes in hemodynamic and respiratory statuses during bronchoscopy or complications did not significantly differ between patients experiencing moderate-to-severe disinhibition and those experiencing none-to-mild disinhibition. CONCLUSIONS Moderate-to-severe disinhibition occurred in 19.5% of patients during bronchoscopy with midazolam. We should focus on disinhibition when patients have depression or are planning to undergo EBUS-TBNA, and sparing the administration of midazolam might reduce the occurrence of disinhibition.

Abstract
BACKGROUND Patients undergoing bronchoscopic procedures may develop hypoxemia and severe complications. High-flow nasal cannula (HFNC) may prevent hypoxemic events during bronchoscopy. We conducted a systematic review of randomized controlled trials (RCTs) to evaluate the effectiveness of HFNC in these patients. METHODS We conducted a search in PubMed, Embase, and the Cochrane Library for RCTs published before November 2021. Individual effect sizes were standardized, and a meta-analysis was performed to calculate the pooled effect size using random-effects models. The primary outcome was the incidence of hypoxemic events (oxygen saturation [SpO2] < 90%) during bronchoscopy. Secondary outcomes included the incidence of interrupted bronchoscopy due to desaturation, lowest SpO2 during bronchoscopy, partial pressure of oxygen (PaO2), partial pressure of carbon dioxide (PaCO2), end-tidal CO2 (EtCO2) at the end of bronchoscopy, and the incidence of intubation after the procedure. RESULTS Five trials involving 257 patients were reviewed. The incidence of hypoxemic events was lower in the HFNC group than in the conventional oxygen therapy group (risk ratio, 0.25; 95% confidence interval [CI], 0.14-0.42). The lowest SpO2 during the procedure was significantly higher in the HFNC group than in the conventional oxygen therapy group (weighted mean difference [WMD], 7.12; 95% CI, 5.39-8.84). PaO2 at the end of the procedure was significantly higher in the HFNC group than in the conventional oxygen therapy group (WMD, 20.36; 95% CI, 0.30-40.42). The incidence of interrupted bronchoscopy due to desaturation, PaCO2 and EtCO2 at the end of the procedure, and the incidence of intubation after the procedure were not significantly different between groups. CONCLUSIONS HFNC may reduce the incidence of hypoxemic events and improve oxygenation in patients undergoing bronchoscopy.

Abstract
Bronchoscopy is one of the basic invasive procedures in pulmonology accompanied by patients’ anxiety. This study aimed to find an association between predictors of state anxiety/depression and patient’s quality of life (QOL) with pulmonary symptoms undergoing diagnostic flexible video bronchoscopy (FVB). A total of 125 adult patients before FVB were included in a prospective observational study. The quality of life (QOL) was assessed by WHOQOL-BREF questionnaire, the depression possibility by the Beck’s Depression Inventory-II (BDI-II), and the anxiety level by Spielberger’s State-Trait Anxiety Inventory (STAI-S; STAI-T). Results show that the older patients and patients with more comorbidities showed a significantly higher anxiety level. The previous FVB under deep sedation significantly reduced state anxiety. A significantly positive association was found between the STAI score and total BDI-II score. More severe symptoms of anxiety were especially related to lower QOL (physical health, psychological and environmental domains) in patients. Statistically higher trait anxiety in lower social QOL domain scores was observed. Our findings show that high state and trait anxiety were associated with higher depression scores and lower quality of life in the elderly. It seems that the elderly and patients at risk of depression development require more attention in the clinical setting to minimize the anxiety accompanying the bronchoscopy.

Abstract
Pleuroscopy or medical thoracoscopy is the second most common utilized procedure after bronchoscopy in the promising field of interventional pulmonology. Its main application is for the diagnosis and management of benign or malignant pleural effusions. Entry into the hemithorax is associated with pain and patient discomfort, whereas concurrently, notable pathophysiologic alterations occur. Therefore, frequently procedural sedation and analgesia is needed, not only to alleviate the patient's emotional stress and discomfort by mitigating the anxiety and minimizing the pain but also for yielding better procedural conditions for the operator. The scope of this review is to present the physiologic derangements occurring in pleuroscopy and compare the various anesthetic techniques and sedative agents that are currently being used in this context.

Abstract
Background Data on discomfort and complications from research bronchoscopy in chronic obstructive pulmonary disease (COPD) and asthma is limited. We present complications and discomfort occurring within a week after bronchoscopy, and investigate personal and procedural risk factors. Methods 239 subjects with COPD, asthma or without lung disease underwent research bronchoscopies as part of a microbiome study of the lower airways (the MicroCOPD study). Bronchoscopy was done in the supine position with oral scope insertion with the option of light conscious alfentanil sedation. Sampling consisted of protected specimen brushes, bronchoalveolar lavage, small volume lavage and for some, endobronchial biopsies. Bleeding, desaturation, cough, haemodynamic changes, dyspnoea and other events that required an unplanned intervention or early termination of bronchoscopy were prospectively recorded. Follow-up consisted of a telephone interview where subjects rated discomfort and answered questions about fever sensation and respiratory symptoms in the week following bronchoscopy. Results An unplanned intervention or early termination of bronchoscopy was required in 25.9% of bronchoscopies. Three subjects (1.3%) experienced potentially severe complications, of which all recovered without sequelae. COPD subjects experienced more dyspnoea than controls. Sedation and lower age was associated with less unplanned intervention or premature termination. About half of the subjects (47.7%) reported fever. Discomfort was associated with postprocedural fever, dread of bronchoscopy, higher score on the COPD Assessment Test and never-smoking. In subjects undergoing more than one bronchoscopy, the first bronchoscopy was often predictive for complications and postprocedural fever in the repeated bronchoscopy. Conclusion Research bronchoscopies were not associated with more complications or discomfort in COPD subjects. 47.7% experienced postbronchoscopy fever sensation, which was associated with discomfort.

Abstract
Abstract
Objectives Acute pain management in opioid users can be challenging in the perioperative period. This study focuses on whether use of opioids increases sedation medication requirements in patients undergoing port placement under moderate sedation.
Materials and Methods A retrospective review was performed on all patients undergoing port placement between June 1, 2017, and June 30, 2019. Exclusion criteria included receiving general anesthesia, no sedation, and errors in data entry. Data collection included demographics, use of opioids, benzodiazepines, antidepressants, tobacco, alcohol, and sedation data.
Results Opioid, benzodiazepine, and selective serotonin reuptake inhibitors (SSRIs)/serotonin-norepinephrine reuptake inhibitors (SNRIs) use was significantly associated with higher sedation drug dose requirements. Patients using opioids required 10.5% higher doses of midazolam compared with nonusers. Benzodiazepine users required 16.3% additional dosage of midazolam than nonusers. Finally, patients on SSRIs/SNRIs medications required 11.8% higher midazolam dosing when compared with nonusers.
Conclusion Anticipating higher needs of sedation medications during procedures in patients with history of psychotropic agents use can allow for more effective sedation and patient satisfaction. More patient and provider awareness is needed on this topic, as health care policy is moving toward value-based healthcare, with patient satisfaction surveys being one of its indicators.

Abstract
BACKGROUND Conscious sedation guided by bispectral index (BIS) during bronchoscopy has been proved to be a feasible approach. This study aimed to investigate the safety and efficacy of dexmedetomidine combined with midazolam for undergoing conscious sedation during bronchoscopy. METHODS The trial was registered prior to patient enrollment at the Chinese Clinical Trial Registry. Patients were randomized into DEX group (dexmedetomidine combined with midazolam) and FEN group (fentanyl combined with midazolam). Bronchoscopy was performed under awake sedation titrated to a BIS level of 60-80. The primary endpoint was the incidence of hypoxia, the secondary endpoint was the incidence of bradycardia and hypotension, effect of sedation including satisfaction degree (VAS) of the operators and patients and patients' willingness to undergo bronchoscopy again. RESULTS A total of 222 cases in DEX group and 211 cases in FEN group completed the study. The incidence of hypoxia and tachycardia in DEX group was lower than that in FEN group (8.1% vs 14.7%, 10.4% vs 19.0%, p < 0.05), and the incidence of hypotension and bradycardia in DEX group was higher than that in FEN group (6.8% vs 0, 15.3% vs 8.1%, p < 0.05). Midazolam dosage was significantly lower in the DEX group than in the FEN group, and the duration of surgery was significantly longer in the DEX group. The differences in intraoperative discomfort of VAS score, satisfaction VAS score, and willingness rate to undergo bronchoscopy again were not statistically significant between the two groups. In addition, the proportion of "procedural interference by patient movement" in DEX group was higher than that in FEN group. CONCLUSIONS The conscious sedation regimen of dexmedetomidine combined with midazolam monitored by BIS is considered to be safe and effective during bronchoscopy. The occurrence of hypoxia and tachycardia was less, and the fluctuation of blood pressure and heart rate was mild, but the proportion of bradycardia in dexmedetomidine group was higher than that in fentanyl combined with midazolam group.

Abstract
Background and aim Appropriate sedation is important to the success of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Dexmedetomidine is a sedative agent that operates via the α2 adrenergic agonist, which provides sleep-like sedation with little respiratory suppression. This study compared the efficacy and safety of dexmedetomidine sedation with propofol in cases of EBUS-TBNA. Methods Patients requiring EBUS-TBNA were randomly assigned dexmedetomidine sedation (D, n=25) or propofol sedation (P, n=25). Vital signs, diagnostic yield and the bispectral index (BIS) were recorded throughout the bronchoscopic procedure and recovery period. The tolerance and cooperation of the patients were evaluated using questionnaires. Measurements and results The lowest mean arterial blood pressure in group D (79.2±9.9 versus 72.5±12.9 mmHg, p=0.049) exceeded that in group P, the lowest heart rate was lower (60.9±10.2 versus 71.4±11.8 beats·min−1, p=0.006) and the mean BIS during sedation was significantly higher (84.1±8.3 versus 73.6±5.7, p<0.001). Patients in group D were more likely to report perceiving procedure-related symptoms and express an unwillingness to undergo the bronchoscopy again, if indicated (41.1 versus 83.3%, p=0.007). One subject in group D aborted EBUS-TBNA due to intolerance. Many of the variables in the two groups were similar, including the proportion of hypoxaemic events, recovery times, patient cooperation and diagnostic yield. Conclusions The effects of dexmedetomidine on haemodynamics were in line with its pharmacodynamic features. Patients who received dexmedetomidine were more likely than those who received propofol to perceive the procedures. Overall, dexmedetomidine did not prove inferior to propofol sedation in terms of patient cooperation or diagnostic yield. Compared to propofol sedation for EBUS-TBNA, dexmedetomidine provided patients lighter sedation with lower heart rates and less decrease in blood pressure. The recovery times, hypoxaemia, cooperation and diagnostic yield in the two groups were similar.https://bit.ly/33qgEj3

Abstract
INTRODUCTION The safety of bronchoscopy in obese patients and those with obstructive sleep apnea (OSA) is unclear. Our objective was to evaluate the incidence of complications during bronchoscopy under moderate sedation in obese patients and to assess the impact of OSA, body mass index (BMI), and duration of the procedure. METHODS We performed a retrospective study in adult patients undergoing bronchoscopy from January 2010 to August 2019. All patients with BMI > 30 kg/m2 were included. Logistic regression analyses were used to identify the factors associated with all-complications and respiratory complications. RESULTS A total of 345 obese patients were identified. The average BMI in our cohort was 35.3 ± 5.1 kg/m2 . During the pre-procedure risk assessment, 165 (47.8%) patients were labelled as "suspected OSA." The most common doses of sedation given during the bronchoscopies were fentanyl 50 mcg (34.5%) and midazolam 3 mg (33.6%). The incidence of major complications was 0.6% and minor complications were 41.2%. Minor respiratory (22.9%) and cardiac (26.4%) complications were common. No deaths occurred due to bronchoscopy. Factors that were associated with increased respiratory complications were female gender, suspected OSA, and bronchoscopy duration 20-30 minutes and bronchoscopy duration greater than 1 hour. CONCLUSION Bronchoscopy under moderate sedation performed in obese patients is safe; however, increased risk may exist with females, increased procedure time, and suspected OSA.

Abstract
Background The aim of this study was to compare the effects of dexmedetomidine versus midazolam on the dreaming of patients undergoing flexible bronchoscopy during general anesthesia. Material/Methods Patients undergoing flexible bronchoscopy under general anesthesia were randomly divided into a dexmedetomidine group (Group D, n=40) and a midazolam group (Group M, n=40). In group D, patients received 0.5 μg/kg dexmedetomidine and in group M patients received 0.05 mg/kg midazolam intravenously 10 min prior to induction. After bronchoscopy and recovery, a modified Brice questionnaire was used to immediately evaluate the incidence of dreaming of patients. Dreamers were required to complete a 5-point Likert scale survey regarding the contents of their dreams (emotion, voice and movement, memorability) if dreaming was reported. Ramsay Sedation Scale score (Ramsay score) and Visual Analogue Scale (VAS) score were assessed and recorded. Results Patients in group D had higher Ramsay scores and VAS scores (2.9±0.6 and 79.4±4.0, respectively) than group M (2.4±0.7 and 75.0±6.0, respectively), with a statistically significant difference (P<0.05) between groups. The incidence and memorability of dreaming were significantly lower in group D (17.5%) than group M (37.5%, P<0.05), whereas no significant difference was found in emotion, voice, and movement scores of dreaming. Conclusions Compared to midazolam, pre-injection of dexmedetomidine before induction significantly decreased the incidence of dreaming in patients undergoing flexible bronchoscopy during general anesthesia, without producing undesirable effects on the content of dreams (most of them were pleasant), produces a more efficacious sedation effect during the recovery period and improves the comfort level and satisfaction of patients.

Abstract
Although sedation for bronchoscopy improves patient comfort, there is a risk of oversedation in elderly patients. Only a few studies have evaluated the efficacy and safety of sedation for bronchoscopy in elderly patients.This study retrospectively analyzed records of 210 patients who underwent transbronchial brushing and/or biopsy under midazolam sedation at National Hospital Organization Omuta National Hospital between June 2017 and October 2019. Patients were administered 1 mg midazolam following 10 mL 4% lidocaine inhalation. When sedation was insufficient, 0.5 mg midazolam was administered additionally. Diagnostic yield, incidence of complications, amount of oxygen supplementation, decreases in percutaneous oxygen saturation (SpO2), changes in blood pressure, and degree of comfort were analyzed.Patients were divided into the elderly (n = 102) and non-elderly (n = 108) groups. No significant differences were observed in diagnostic yield and procedure time between the 2 groups, and no severe adverse events were noted in the elderly group. The degree of comfort during bronchoscopy was significantly higher in the elderly group. In patients administered < 2 mg midazolam, the amount of oxygen supplementation and decreases in SpO2 were significantly smaller in the elderly group compared to the non-elderly group.The risk of adverse events related to midazolam sedation in bronchoscopy does not increase with age, and sedation improves comfort during flexible bronchoscopy in elderly patients. Moreover, a total dose of midazolam <2 mg is safe for elderly patients undergoing bronchoscopy.

BACKGROUND Flexible bronchoscopy is one of the essential procedures for the diagnosis and treatment of pulmonary diseases. The purpose of this study was to identify the risk factors associated with the occurrence of hypoxia in adults undergoing flexible bronchoscopy under sedation. METHODS We retrospectively analyzed 2,520 patients who underwent flexible bronchoscopy under sedation at our tertiary care university hospital in South Korea January 1, 2013-December 31, 2014. Hypoxia was defined as more than 5%-point reduction in the baseline percutaneous oxygen saturation (SpO2) or SpO2 <90% for >1 minute during the procedure. RESULTS The mean age was 64.7±13.5, and 565 patients developed hypoxia during the procedure. The mean sedation duration and midazolam dose for sedation were 31.1 minutes and 3.9 mg, respectively. The bivariate analysis showed that older age, a low forced expiratory volume in one second (FEV1), use of endobronchial ultrasound, the duration of sedation, and the midazolam dose were associated with the occurrence of hypoxia during the procedure, while the multivariate analysis found that age >60 (odds ratio [OR], 1.32), a low FEV1 (OR, 0.99), and a longer duration of sedation (>40 minutes; OR, 1.33) were significant risk factors. CONCLUSION The findings suggest that patients older than age 60 and those with a low FEV1 tend to develop hypoxia during the bronchoscopy under sedation. Also, longer duration of sedation (>40 minutes) was a significant risk factor for hypoxia.

Abstract
The modern approach to the multimodal scheme of postoperative analgesia includes the mandatory use of drugs that have a small number of side effects and at the same time have a polymodal effect on the pathogenetic links of pain development. Nefopam hydrochloride is able to prevent the development of: opioid hyperalgesia, stop pain stimuli without respiratory depression, affect platelet aggregation and the condition of the mucous membrane and motility of the gastrointestinal tract, which distinguishes it from classical NSAIDs. Nefopam hydrochloride is characterized by a low risk of addiction with prolonged use, a pronounced anti-sensory effect, especially significant at the stage of awakening and in the early postoperative period.
Postoperative analgesia based on nefopam hydrochloride as a component of multimodal analgesia is effective and safe in the absence of absolute contraindications. The planned use of nefopam hydrochloride for the correction of pain reduces complications in the postoperative period and improves the quality of life of patients. Nefopam hydrochloride is one of the most effective drugs for the correction of postoperative tremor syndrome. The use of nefopam hydrochloride as a drug, which is a part of premedication before surgical interventions and a component of multimodal analgesia, improves the quality of the postoperative period due to: reduction of pain syndrome, planned correction of postoperative tremor syndrome and correction of complications arising from inadequate treatment of pain syndrome.

Abstract
Background There are limited data regarding the efficacy and safety of remifentanil sedation for diagnostic bronchoscopy. The aim of this study was to evaluate the clinical efficacy and safety of remifentanil by comparing it with those of conventional drugs, midazolam and propofol. Methods A retrospective study of 186 patients who underwent diagnostic bronchoscopy at Chonbuk National University Hospital was performed. Patients were classified into the remifentanil group and midazolam/propofol group according to the drugs used during bronchoscopy. Results Of the 186 patients, 111 patients received remifentanil and 75 received midazolam/propofol during the bronchoscopy. The proportion of patients who required bronchoscopy for endobronchial inspection alone was significantly higher in the midazolam/propofol group than in the remifentanil group (93.3% vs. 73.0%; p < 0.001). In contrast, the proportion of patients who required more invasive procedures, such as bronchoscopic biopsy, bronchoalveolar lavage, or transbronchial lung biopsy, was significantly higher in the remifentanil group than in the midazolam/propofol group (27.0% vs. 6.7%; p < 0.001). The recovery time was significantly shorter in the remifentanil group than in the midazolam/propofol group (mean 6.4 min vs. 11.6 min, p < 0.001). There were no significant differences between the groups with regard to safety events including desaturation, hypotension, and arrhythmia. Conclusions Despite the higher proportion of patients who underwent more invasive procedures in the remifentanil group than in the midazolam/propofol group, there was no significant difference in safety events between the groups. Those in the remifentanil group also demonstrated a faster recovery time than those in the midazolam/propofol group.

Abstract
Flexible bronchoscopy is a commonly performed procedure in pulmonary medicine. The common complications following bronchoscopy include minor bleeding, transient hypoxaemia, pneumothorax and others. Pneumothorax during diagnostic flexible bronchoscopy is mainly encountered after performing transbronchial lung biopsy. Iatrogenic pneumothorax is uncommon when lung biopsy is not performed. Herein, we report the unusual occurrence of pneumothorax following bronchoscopic suctioning while removing a mucus plug.

Abstract
The objective of this research was to study the effectiveness and safety of proceduralist given sedation in pediatric flexible bronchoscopy. Flexible bronchoscopy was performed in all 267 patients. All patients received midazolam and/or ketamine. The median (interquartile range [IQR]) age of the studied population was 16 (18) months. The indication of bronchoscopy varied. The mean ± standard deviation (SD) dose of midazolam was 0.109 (0.03) mg/kg and that of ketamine was 1.17 (0.43) mg/kg. We observed minor side effects of procedural sedation. All patients underwent procedure successfully. Flexible bronchoscopy in children can be safely performed under sedation using a combination of midazolam and ketamine.

Abstract
This study aimed to investigate the risk factors and whether acute hypercapnia contributes to postoperative delirium (POD) during bronchoscopic intervention under general anesthesia or deep sedation.A prospective study was conducted with 119 consecutive patients who had undergone bronchoscopic intervention between February 2016 and December 2016 at the Emergency General Hospital.Twenty-eight patients (23.8%) were diagnosed with POD. The patients were divided into 2 groups: the POD (n = 28) and the control group (n = 91). The mean age of the POD group was higher than that of the control group (P < .01). All the blood gas values, PaCO2 (P < .01), PaO2 (P < .01), and PH (P < .01), were significantly different. Multivariate analyses revealed that age (P < .01), operation duration (P = .01), and PO2 (P = .01) were independent predictive factors of POD, while hypercapnia (P = .54) was established as not being a predictive factor of POD.Age, operation duration, and PO2 were determined as independent predictive factors of POD, whereas moderate hypercapnia is not likely to contribute to POD in patients undergoing bronchoscopic intervention.

Abstract
Capnography involves the measurement of end-tidal CO2 (EtCO2) values to detect hypoventilation in patients undergoing sedation. In a previous study, we reported that initiating a flexible bronchoscopy (FB) examination only after detecting signs of hypoventilation could reduce the risk of hypoxemia without compromising the tolerance of the patient for this type of intervention. We hypothesize that hypoventilation status could be determined with greater precision by combining thoracic impedance-based respiratory signals, RESP, and EtCO2 signals obtained from a nasal-oral cannula. Retrospective analysis was conducted on RESP and EtCO2 waveforms obtained from patients during the induction of sedation using propofol for bronchoscopic examination in a previous study. EtCO2 waveforms associated with hypoventilation were then compared with RESP patterns, patient variables, and sedation outcomes. Signals suitable for analysis were obtained from 44 subjects, 42 of whom presented indications of hypoventilation, as determined by EtCO2 waveforms. Two subtypes of hypoventilation were identified by RESP: central-predominant (n = 22, flat line RESP pattern) and non-central-predominant (n = 20, RESP pattern indicative of respiratory effort with upper airway collapse). Compared to cases of non-central-predominant hypoventilation, those presenting central-predominant hypoventilation during induction were associated with a lower propofol dose (40.2 ± 18.3 vs. 60.8 ± 26.1 mg, p = 0.009), a lower effect site concentration of propofol (2.02 ± 0.33 vs. 2.38 ± 0.44 µg/ml, p = 0.01), more rapid induction (146.1 ± 105.5 vs. 260.9 ± 156.2 s, p = 0.01), and lower total propofol dosage (96.6 ± 41.7 vs. 130.6 ± 53.4 mg, p = 0.04). Hypoventilation status (as revealed by EtCO2 levels) could be further classified by RESP into central-predominant or non-central-predominant types. It appears that patients with central-predominant hypoventilation are more sensitive to propofol during the induction of sedation. RESP values could be used to tailor sedation management specifically to individual patients.

Abstract
Diagnostic bronchoscopy and tissue sampling techniques using forceps (endobronchial biopsy [EBB] and transbronchial biopsies [TBB]) or needle aspiration (transbronchial needle aspiration-TBNA), all performed with a flexible bronchoscope, are the basic elements of any interventional procedure. The flexible fibrobronchoscopy allows the visualization of the airways and is used both for diagnostic and therapeutic purposes. The working channel of both fibrobronchoscopes with optical fibers and videobronchoscopes, even if of relatively small diameter, allows the insertion of various diagnostic and therapeutic accessories. Fiber optic systems have been widely replaced by video cameras using a miniaturized charge-coupled device camera positioned at the end of the scope that provides electronic transmission of images to a monitor. The indications for both diagnostic and therapeutic fibrobronchoscopy derive from a correct evaluation of symptoms and objective signs of the patient and from the correct interpretation of imaging methods. Although bronchoscopy techniques keep evolving at a rapid pace, basic procedures such as bronchoalveolar lavage, transbronchial lung biopsy, and transbronchial needle aspiration still play a key role in pulmonary disease diagnostics, and therefore, these methods must still be part of the training of interventional pulmonologists. Trainees will acquire a thorough knowledge of thoracic anatomy and become skilled in the interpretation of thoracic imaging, after which they will be given a theoretical and practical training course on virtual reality simulators, on animal or cadaver models, the effectiveness of which has been fully demonstrated by scientific studies. Specific DOPS tests have been developed for a qualitative evaluation of procedures on simulators, on animal models and on the patient.

Abstract
BACKGROUND While the complexity of flexible bronchoscopy has increased, standard options for moderate sedation medications have not changed in three decades. There is a need to improve moderate sedation while maintaining safety. Remimazolam was developed to address shortcomings of current sedation strategies. METHODS A prospective, double-blind, randomized, multicenter, parallel group trial was performed at 30 US sites. The efficacy and safety of remimazolam for sedation during flexible bronchoscopy were compared with placebo and open-label midazolam. RESULTS The success rates were 80.6% in the remimazolam arm, 4.8% in the placebo arm (P < .0001), and 32.9% in the midazolam arm. Bronchoscopy was started sooner in the remimazolam arm (mean, 6.4 ± 5.82 min) compared with placebo (17.2 ± 4.15 min; P < .0001) and midazolam (16.3 ± 8.60 min). Time to full alertness after the end of bronchoscopy was significantly shorter in patients treated with remimazolam (median, 6.0 min; 95% CI, 5.2-7.1) compared with those treated with placebo (13.6 min; 95% CI, 8.1-24.0; P = .0001) and midazolam (12.0 min; 95% CI, 5.0-15.0). Remimazolam registered superior restoration of neuropsychiatric function compared with placebo and midazolam. Safety was comparable among all three arms, and 5.6% of the patients in the remimazolam group had serious treatment-emergent adverse events as compared with 6.8% in the placebo group. CONCLUSIONS Remimazolam administered under the supervision of a pulmonologist was effective and safe for moderate sedation during flexible bronchoscopy. In an exploratory analysis, it demonstrated a shorter onset of action and faster neuropsychiatric recovery than midazolam.

Abstract
Background: Flexible bronchoscopy (FB) can be performed under bronchoscopist administered moderate sedation (BAMS) with a midazolam/fentanyl combination or general anesthesia (GA). However, the outcome of BAMS has not been well established in children. Currently, most of the centers prefer FB under GA. Both techniques have their advantages and disadvantages with implications for safety, complications, and diagnostic yield. The primary objective of our study was to evaluate the safety, time efficiency, and cost-effectiveness of FB under BAMS as compared with FB under GA in a similar setting. Methods: We performed a retrospective chart review to compare BAMS versus GA for FB in children. We recruited BAMS children (n = 295) from University of Florida (UF) Health Shands Children's Hospital, and GA children (n = 100) from Penn State Children's Hospital (PSHCH). Both the groups had similar indications, complexities, and procedural environments. Comparisons of various time-intervals including preprocedure time, sedation-induction time, scope time, and post-procedure time among different BAMS versus GA age-groups were the primary outcomes. The secondary outcomes were the determination of the rates of complications, the dosages of sedative/anesthetic, cost-effectiveness, and sedation patterns under BAMS. Results: FB under BAMS required significantly higher preprocedure times and sedation-induction times (P < 0.001** and P < 0.001** respectively) but shorter scope and post-procedure times compared with the GA group times (P < 0.001** and P < 0.001** respectively). Younger children had a deeper level of sedation for an extended period under BAMS. The costs for the sedation services and the complication rates were lower in the BAMS group compared with the GA group. Conclusion: Our study demonstrated the feasibility of BAMS in children. FB under BAMS had an advantage of lower cost and fewer procedural complications compared with FB under GA. Despite that, the safety of BAMS could not be conclusively established from this retrospective study. Moreover, BAMS can potentially compromise the diagnostic yield because the bronchoscopist is also responsible for monitoring sedation and managing the airway.

Abstract
Benign tracheoesophageal fistula (TEF) results from an abnormal communication between the posterior wall of the trachea or bronchi and the adjacent anterior wall of the esophagus. It can be acquired or congenital. The onset of the TEF has a negative impact on the patient's health status and quality of life because of swallowing difficulties, recurrent aspiration pneumonia, and severe weight loss. Several acquired conditions may cause TEF. The most frequent is prolonged orotracheal intubation (75% of the cases). Usually, there is an erosion of the tracheal and esophageal wall by the continuous pressure between the endotracheal tube and the esophageal wall; particularly in the presence of a nasogastric or feeding tube within the esophageal lumen. Furthermore, tracheal stenosis is often associated, and adds complexity to the disease. Preparation for the surgical procedure may take weeks or even months. It includes definitive weaning from mechanical ventilation, treatment of respiratory infection, physiotherapy, and correction of malnutrition through enteral feeding. Surgical repair of a TEF is an elective procedure. It consists of division of the fistula, suture of the esophagus and trachea and protection of the suture lines with a buttressed muscle flap. TEF repair is a complex and challenging procedure, thus, high morbidity and mortality are expected. Nonetheless, surgical management yields excellent long-term results, and it should be considered the first-line treatment for this condition. Definitive fistula closure occurs in about 90-95% of the cases.

Abstract
PURPOSE OF REVIEW This article focuses on the issue of sedation provided either by proceduralists or anesthesiologists for advanced bronchoscopy procedures. The relative merits of both approaches are presented. Current evidence from the literature and guideline recommendations relevant to this topic are reviewed. RECENT FINDINGS In general, patient and proceduralist satisfaction as well as patient safety are increased when intravenous sedation is provided for advanced bronchoscopic procedures. However, guidelines by various societies remain vague on defining the appropriate level of care required when providing sedation for these procedures. In addition, targeted depth of sedation varies considerably among practitioners. While in some settings, nonanesthesiologist-administered propofol sedation has been proven safe; nevertheless, its use is controversial, especially in the bronchoscopy suite. SUMMARY The role of the anesthesiologist in sedation for advanced bronchoscopy remains undefined. When deep sedation for prolonged interventional procedures is needed or when dealing with patients who have multiple comorbidities, an anesthesiologist should be involved.

Abstract
PURPOSE Interventional pulmonology is a growing subspecialty of pulmonary medicine with flexible and rigid bronchoscopies increasingly used by interventional pulmonologists for advanced diagnostic and therapeutic purposes. This review discusses different technical aspects of anesthesia for interventional pulmonary procedures with an emphasis placed on pharmacologic combinations, airway management, ventilation techniques, and common complications. SOURCE Relevant medical literature was identified by searching the PubMed and Google Scholar databases for publications on different anesthesia topics applicable to interventional pulmonary procedures. Cited literature included case reports, original research articles, review articles, meta-analyses, guidelines, and official society statements. PRINCIPAL FINDINGS Interventional pulmonology is a rapidly growing area of medicine. Anesthesiologists need to be familiar with different considerations required for every procedure, particularly as airway access is a shared responsibility with pulmonologists. Depending on the individual case characteristics, a different selection of airway method, ventilation mode, and pharmacologic combination may be required. Most commonly, airways are managed with supraglottic devices or endotracheal tubes. Nevertheless, patients with central airway obstruction or tracheal stenosis may require rigid bronchoscopy and jet ventilation. Although anesthetic approaches may vary depending on factors such as the length, complexity, and acuity of the procedure, the majority of patients are anesthetized using a total intravenous anesthetic technique. CONCLUSIONS It is fundamental for the anesthesia provider to be updated on interventional pulmonology procedures in this rapidly growing area of medicine.

Abstract
INTRODUCTION Although there is a remarkable increase in diagnostic flexible bronchoscopy (FB) in old patients, safety and efficacy of FB in very old patients remain to be elucidated. In this study, we aimed to evaluate the complications and diagnostic yield of FB in patients aged ≥ 80 years with lung cancer compared with those aged < 80 years. MATERIALS AND METHODS We retrospectively analysed the medical records of 668 consecutive patients, which included 89 patients aged ≥ 80 years (older group) and 579 patients aged < 80 years (younger group) who underwent bronchoscopy for the diagnosis or staging of lung cancer between April 2011 and March 2016. RESULTS The median age of the patients was 82 and 69 years in the older and younger groups, respectively. Performance status and Charlson comorbidity index were comparable between the study groups. Diagnostic yield in the older and younger groups was equivalent, and stage distribution in both the groups was similar. Sixty-one patients (68.5%) received anticancer treatment including surgery, radiation and chemotherapy with cytotoxic or molecular-targeted agents in the older group. There were no statistical differences in the occurrence of overall complications between the two groups. CONCLUSIONS Safety and efficacy of FB in the diagnosis of lung cancer in very old patients are comparable with those of younger patients. Accurate diagnosis established by bronchoscopy leads to appropriate treatment decision in very old patients.

Abstract
Background This study aims to verify the correlation of bispectral index (BIS) and Richmond agitation sedation scale (RASS) for evaluating these and explore possibility of replacing RASS with BIS. Methods This retrospective cohort study consisted of 74 patients who were collected from the third Intensive Care Unit (ICU) ward of XXX Hospital between May 2012 and June 2015 in this retrospective study. Sedation levels were evaluated using the 10-grade RASS and were continuously monitored with a BIS monitor during the procedure every 5 minutes. BIS values and RASS scores were recorded. Results Patients were divided into dexmedetomidine (n=31) and midazolam (n=43) groups, and 342 paired data were collected. A statistically significant correlation existed between BIS values and RASS scores either in all patients undergoing flexible fiberoptic bronchoscopy (FFB) or in dexmedetomidine and midazolam groups at different time points. Correlation coefficient was higher in midazolam group compared with dexmedetomidine group at different time points (P<0.05). Conclusions A correlation was observed between BIS and RASS for evaluating depth of sedation in ICU patients undergoing FFB (P<0.05). Study results indicated that BIS monitoring is a meaningful tool, which can be applied as an adjunctive and alternative method to assess sedation, especially for high-risk patients who are prone to be under- or over-sedation.

Abstract
AIM To evaluate the safety and efficacy of sedating pediatric patients for outpatient flexible bronchoscopy.
METHODS A retrospective chart review was conducted for all children, age 17 years or under who underwent flexible bronchoscopy under deep sedation in an outpatient hospital-based setting. Two sedation regimens were used; propofol only or ketamine prior to propofol. Patients were divided into three age groups; infants (less than 12 mo), toddlers (1-3 years) and children (4-17 years). Demographics, indication for bronchoscopy, sedative dosing, sedation and recovery time and adverse events were reviewed.
RESULTS Of the total 458 bronchoscopies performed, propofol only regimen was used in 337 (74%) while propofol and ketamine was used in 121 (26%). About 99% of the procedures were successfully completed. Children in the propofol + ketamine group tend to be younger and have lower weight compared to the propofol only group. Adverse events including transient hypoxemia and hypotension occurred in 8% and 24% respectively. Median procedure time was 10 min while the median discharge time was 35 min. There were no differences in the indication of the procedure, propofol dose, procedure or recovery time in either sedative regimen. When compared to other age groups, infants had a higher incidence of hypoxemia.
CONCLUSION Children can be effectively sedated for outpatient flexible bronchoscopy with high rate of success. This procedure should be performed under vigilance of highly trained providers.
