In patients with high levels of fear and anxiety, it is recommended to perform dental procedures under sedation or general anesthesia depending on the nature of the procedure. In dental treatment under anesthesia, it is important that the procedure is comfortable and well tolerated by the patient. In addition, patient comfort is important in all dental procedures to prevent the development of avoidance behavior. During dental procedures performed under anesthesia, the oral cavity is completely within the scope of the surgical or procedure field. In this respect, sedation and general anesthesia in dental procedures and operations have specific risks and challenges.Since there is a risk of respiratory depression, hypoxia and hypercarbia during deep sedation, non-invasive ventilation support provided to patients with airway devices would be beneficial. In the research clinics where the study will be conducted, deep sedation with non-invasive mechanical ventilation support using a nasal CPAP (Continuous Positive Airway Pressure) mask or nasal airway is applied during the extraction of impacted molars. Thus, many dental procedures are routinely performed under deep sedation without the need for general anesthesia. There are very limited data in the literature on the use of a nasal CPAP mask during sedation for different procedures in patients with obstructive sleep apnea or obesity. However, no study comparing ventilation support during deep sedation with nasal CPAP mask and nasal airway has been found in the literature. The aim of this study is to compare the non-invasive ventilation support provided with 2 different airway devices during the procedure in terms of intraoperative and postoperative related complications, ventilation parameters, patient and surgeon satisfaction. The hypothesis of the study is that two different ventilation support methods during deep sedation may be superior to each other in terms of anesthesia quality, postoperative complications related to airway devices, patient and surgeon satisfaction. In the study, a total of 60 patients (Group airway, n;30, Group Mask, n;30) from 2 centers are planned to be included in the study by performing power analysis with a statistical power of the trial \>0.8. The permutation method will be applied within the scope of the restricted randomization method to determine the group of patients to be included.

The current practice of anesthesia for atrial fibrillation catheter ablation （CA） procedure is inconsistent, including general anesthesia, deep sedation, and conscious sedation.Due to the nature of deep sedation, it has been continuously gaining its position as one of the crucial components in standard practices of atrial fibrillation ablation during the last decade. Currently, a considerable number of procedures have been done using conscious sedation. Previous studies explored the benefits obtained from the employment of deep sedation in AF ablation procedures, mainly focused on pain reduction and intra-procedural safety. However, the benefits on long-term rhythmic outcomes, peri-procedural safety as well as benefits on procedural parameters and peri-procedural experiences from patients/ablators/lab staff have yet not to be thoroughly studied. We plan to conduct a prospective, multicenter, randomized, controlled trial to evaluate the benefits of deep sedation in catheter ablation of paroxysmal and persistent AF in multiple prospective, i.e., quantified intraprocedural patients / physicians / lab staffs / mapper clinical specialist experiences, and the procedure safety.
NCT05701839
Hysteroscopy is used to examine and treat uterine diseases. Because of severe pain due to uterine distention and cervical dilatation, deep sedation usually be provided during this procedure. Respiratory depression and upper airway obstruction are main respiratory complications during deep sedation. Face mask and nasopharyngeal airway are main airway management during deep sedation. Oxygen reserve index is a non-invasive parameter, it reflects the moderate hyperoxia statues. In this study, investigators compare the effect of face mask and nasopharyngeal airway management on oxygenation during deep sedation in participants undergoing hysteroscopy. Investigators also investigate whether oxygen reserve index monitoring reduce the incidence of hypoxemia.

This study aimed to compare the effectiveness of intranasal Dexmedetomidine sedation at Dose of 2 mcg/kg and 4 mcg/kg in Children Undergoing MRI at Cipto Mangunkusumo Hospital
NCT04695509
Propofol (Propofol Kabi, Registration number from the State Register of Medicines - 000875) is a widely used intravenous anesthetic. It is well known about different effects of propofol infusion, including euphoria, psycholalia, disinhibition, talkativeness, satisfaction etc. However, the basic mechanisms of such effects remain unknown. We suppose that propofol sedation with various levels of sedation (from light to deep) leads to neuromediators changes. We examine dopamine, noradrenaline, acetylcholine, GABA and serotonin in peripheral venous blood before, during and after propofol sedation. Therefore, we suppose drugs for sedation, in particular, propofol will affect neuromediators concentration.

Especially, the chronologic sequence of the quantified plasma levels during sedation and during wake-up as well as the correlation to dose and sedation depth will be focused.
NCT04333719
This nation-wide, multicentric, prospective and cross-sectional study aims to estimate the prevalence of deep sedations (i.e. with a -4 or -5 score at the Richmond scale at the induction time) for patients in terminal phase and receiving cares from a specialized palliative care facility (palliative care units, dedicated beds in acute units, mobile teams for inpatient or outpatients or home-based structures) in France.
NCT02903407
This study aims to examine the use of protocol directed sedation using the Duke PAD protocol with the current sedation medications of propofol or dexmedetomidine compared to the PAD protocol with midazolam, per cardiac intensive care unit (CICU) usual care, as an initial step toward understanding the best management of sedation in these patients.
NCT03893877
Abstract Backgrounds and objectives: Dental treatments, especially in children who can not be cooperated, may require deep sedation due to intense anxiety and fear. During sedation oxygen is usually given to the patients by nasal cannula. Investigators want to use nasal mask for non-invasive mechanical ventilation for oxygenation of the patient during sedation for dental treatment and described it with nasal cannula. Methods: Seventy three children classified as ASA 1 or 2, aged between 3 to 17 will be included for this study. During deep sedation procedure group M will be applied nasal mask in order to noninvazive mechanical ventilation, group C will be applied nasal cannula connected to the oxygen flowmeter.

Analgo-sedation is standard procedure in anesthesiology practice and is often given for colonoscopy in the setting of daily hospital. Ideally, patients should be sedated with preserved spontaneous breathing and adequate blood O2 saturation. To maintain adequate oxygenation, low-flow O2 (2-6 L/min) is usually delivered through standard nasal catheter which can provide inspired fraction (FiO2) of 40% (low-flow nasal oxygenation - LFNO). Coldness and dryness of LFNO applied may be uncomfortable to patient. Standardly applied intravenous anesthetics can lead to transient ceasing of breathing and O2 desaturation despite LFNO. Respiratory instability can also potentiate circulatory instability - undesirable changes in heart rate (HR) and blood pressure (BP). Unlike LFNO, high-flow heated and humidified nasal oxygenation (HFNO) is characterized by the oxygen-air mixture flow of 20 to 70 L/min up to 100% FiO2. Warm and humidified O2, delivered via soft, specially designed nasal cannula, is pleasant to patient. HFNO develops continuous positive pressure of 3 to 7 cmH2O in upper airway which enables noninvasive support to patient's spontaneous breathing thus prolonging time of adequate O2 saturation. Aim of this study is to compare effect of HFNO and LFNO on oxygenation maintenance before, during and after standardized procedure of intravenous analgo-sedation in normal weight patients of ASA risk I, II and III. Investigators hypothesize that application of HFNO compared to LFNO, in patients with preserved spontaneous breathing during procedural analgo-sedation, will contribute to maintaining of adequate oxygenation, consequentially adding to greater circulatory and respiratory patients' stability. Investigators expect that patients who receive HFNO will better maintain adequate oxygenation regarding improved spontaneous breathing. Also patients will have shorter intervals of blood oxygen desaturation, less pronounced rise in blood CO2 level and lesser fall of blood O2 level, less change in HR and BP. Investigators will have to exactly estimate partial and global respiratory insufficiency (blood CO2 and O2 levels) associated with LFNO and HFNO, which will be done by blood-gas analysis of 3 arterial blood samples collected before, during and after analgo - sedation via previously, in local anesthesia, placed arterial cannula. Possible complications will be explained in written uniformed consent and by anesthesiologist.
NCT03652324
This prospective, randomize study was conducted in a university hospital. Bronchoscopic lung volume reduction (BLVR) coil treatment has recently been introduced into clinical practice as an alternative for patients chronic obstructive pulmonary disease (COPD) with severe refractory heterorogenous emphysema to conventional medical treatment. Thirty two patients diagnosed with (COPD) with severe refractory heterorogenous emphysema undergoing BLVR coil treatment were included in the study. Seventeen procedure were performed under general anesthesia and fifteen procedure were performed under deep sedation-analgesia. in the general anesthesia group peak pressure, air leakage and end-tidal carbon dioxide were recorded. In the both groups pulse oximeter, transcutaneous carbondioxide, recovery time, bronchospasm, laryngospasm, pneumothorax, massive bleeding were recorded.

Sedation may be necessary in intensive care to facilitate diverse therapeutic interventions, but the use of sedative drugs may increase the risk of delirium and long-term cognitive impairment. Thus the implementation and monitoring of sedation remains difficult despite the use of sedation protocols and clinical sedation scores. Attempts to improve sedation monitoring through the use of the electroencephalogram(EEG) have been disappointing. Derived variables based on the unstimulated EEG fail to predict the response to external stimuli at the clinically most relevant light-to-moderate sedation levels, and the overlap between moderate and deep sedation levels is wide. We have demonstrated that long-latency auditory evoked potentials (ERPs)can be used to avoid deep levels of sedation in healthy volunteers during propofol sedation, independent of the concomitant administration of remifentanil. This approach has a potential clinical application for improved monitoring of sedation. Since the effects of different sedative drugs on the EEG may vary widely, the use of ERPs to monitor sedation needs to be evaluated with different sedative drugs. Therefore we will administer two widely used drug combinations (dexmedetomidine/remifentanil and midazolam/remifentanil) in healthy volunteers and record ERPS and processed EEG during clinical relevant sedation levels
