Brief summary
The purpose of this study is to investigate the feasibility of using balanced propofol sedation for bronchoscopy. And screen out the optimal balanced propofol sedation compatibility plan.
Detailed description
Balanced propofol sedation (BPS) is a technique proposed and developed by gastroenterologists. In recent years, multiple studies have confirmed that the use of BPS in gastrointestinal endoscopy can not only ensure patient comfort, but also reduce the incidence of respiratory and circulatory suppression. Moreover, the postoperative recovery time is short. Even for non-anesthesiologists applying BPS in gastrointestinal endoscopy , it has high safety. Compared with gastrointestinal endoscopy, bronchoscopy occupies the respiratory tract and most patients have respiratory system diseases. Therefore, it is more necessary for strict respiratory management and control of patient sedation depth. Traditional midazolam combined with opioid drugs or propofol monosedation cannot effectively meet clinical needs. The excellent sedative and analgesic effects of BPS, as well as its maintenance of respiratory and circulatory functions, make it theoretically very suitable for application in bronchoscopy. However, there is currently a lack of evidence to support the application of BPS in bronchoscopy.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Patient satisfaction | During bronchoscopy. | The investigator needs to use VAS scores to evaluate satisfaction about sedation feeling when they accepted bronchoscopy. The score from 0 (extremely dissatisfied) to 10 (extremely satisfied). |
| Clinical satisfaction | During bronchoscopy. | The investigator needs to use VAS scores to evaluate satisfaction about doctors and nurses when they carry out the operation. The score from 0 (extremely dissatisfied) to 10 (extremely satisfied). |
| Patient's recovery time | The end of bronchoscopy (up to 2 hours). | The investigator needs to record the wake-up time of patients after the end of bronchoscopy. |
| Patient's departure time | The end of bronchoscopy (up to 2 hours). | The investigator needs to record the patient's departure time after the end of bronchoscopy. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Additional frequency of 2% lidocaine during bronchoscopy | During bronchoscopy. | Additional frequency of 2% lidocaine during bronchoscopy. |
| Additional dosage of 2% lidocaine during bronchoscopy | During bronchoscopy. | Additional dosage of 2% lidocaine during bronchoscopy. |
| Additional dosage of propofol during bronchoscopy | During bronchoscopy. | Additional dosage of propofol during bronchoscopy. |
| Adverse reactions after fully awake | The end of bronchoscopy (up to 2 hours). | After fully awake, researcher used the VAS score for adverse reactions during the resuscitation process, such as dizziness, pain, nausea, breathing difficulties, etc. The score from 0 (no uncomfortable) to 10 (extremely uncomfortable). |
| Adverse reactions during bronchoscopy | During bronchoscopy | Record the number of occurrences of hypotension, hypertension, tachycardia, bradycardia, arrhythmias, hypoxemia, apnea, coughing (no wheezing during continuous coughing, considered as one coughing), and physical activity (non directive limb activity) during bronchoscopy. After fully awake, researcher 2 used the VAS score for adverse reactions during the resuscitation process, such as dizziness, pain, nausea, breathing difficulties, etc. |
| Patient's anxiety/depression state | Day before bronchoscopy. 1, 3, 7, and 14 days after bronchoscopy. | Researcher used the Patient Health Questionnaire-8 (PHQ-8) to assess Patient's anxiety/depression state. The total score range of PHQ-8 is 0-24. No depressive symptoms on a score of 0-4, mild on a score of 5-9, moderate on a score of 10-14, and severe on a score of 15 or above. |
| Patient response score during bronchoscopy | During bronchoscopy. | Researcher used the Behavioral Pain Scale for non intubated patients (BPS-NI) to assess their response scores. The tool consists of 3 behavioral domains: facial expressions, movements, and vocalization. The total BPS-IN value can range from 3 (no pain) to 12 (most pain). |
| Induction time | Before bronchoscopy. | Time from administering sedative and analgesic drugs to titration with propofol until MOAA/S 2-3 points. |
| Drug dosage | Before bronchoscopy and during bronchoscopy. | Induced, maintenance and total dose of midazolam, propofol. |
| Additional frequency of propofol during bronchoscopy | During bronchoscopy. | Additional frequency of propofol during bronchoscopy. |
