Filter by:Sedation during flexible bronchoscopy (FB) should maintain an adequate respiratory drive, ensure maximum comfort for the patient, and warrant that the objectives of the procedure are achieved. Nevertheless, the optimal sedation method for FB has yet to be established. This study aimed to compare the standard recommended combination of midazolam-fentanyl (MF) with that of dexmedetomidine-ketamine (DK) for patient sedation during FB. Patients subjected to FB were randomly assigned to a DK (n=25) and an MF group (n=25). The primary outcome was the rate of critical desaturation events (arterial oxygen saturation <80% with nasal oxygen supply 2 L/min). Secondary outcomes included sedation depth, hemodynamic complications, adverse events, and patient and bronchoscopist satisfaction.
The aim of the study is to assess the efficacy of intravenous lidocaine versus intravenous ketamine in treatment of fibromyalgia patients.
The hypothesis of this study is that sedoanalgesia will provide better early neurological recovery than general anaesthesia in acute ischaemic stroke patients undergoing endovascular thrombectomy and to investigate the haemodynamic data of both anaesthetic methods.
The endoscopic surgery of the paranasal sinuses (FESS) requires careful control of arterial pressure to prevent bleeding of the nasal mucosa that may lead to a reduction in the visual field. However, controlled reversible hypotension has been associated with phenomena of peripheral hypoperfusion with possible organ damage on an ischemic basis. Based on the data available in the literature, a mean arterial pressure (MAP) target between 50 and 65 mmHg is considered acceptable. Although blood pressure control is generally ensured through intravenous pharmacological approaches, there is evidence of efficacy with the use of Auriculotherapy medical devices (stimulation of specific points in the ear through the application of Magnetic ball plasters). Proposed pharmacological choices to achieve this result have been multiple, although totally intravenous anesthesia with propofol and opioids seems to be more effective than balanced anesthesia with halogenated agents and opioids. However, this fundamental option requires the administration of antihypertensive drugs to achieve the blood pressure target. Despite common contraindications to individual pharmacological classes, various active principles have been compared. Among these, continuous low-dose nitroglycerin infusion has proven effective due to titratability linked to its short half-life, perioperative complications, and better conditions of peripheral perfusion compared to beta-blockers such as labetalol or esmolol. Based on existing literature data, in our hospital, general anesthesia is typically conducted with intravenous techniques and the continuous administration of low doses of nitroglycerin in continuous infusion (0.01-2 mcg/kg/min). Despite the low dosages, this drug can be burdened with dosage-dependent adverse effects such as orthostatic hypotension, tachycardia, or headache. To reduce the dosage of nitroglycerin, we have borrowed from different contexts hypotensive auriculotherapy techniques (stimulation of specific ear points through the application of magnetic ball plasters), which have proven effective in managing systemic pressure in patients with essential hypertension. These non-pharmacological techniques, already used during general anesthesia for the management of nausea and pain, could prove promising in reducing the use of antihypertensive drugs even in the intraoperative context. The primary hypothesis of our study is that the use of Auriculotherapy medical devices is effective in achieving a hypotensive effect in patients undergoing general anesthesia during FESS surgery.
compare the effectiveness of intranasal dexmedetomidine and midazolam as a premedication in sedation of preschool children in GI endoscopy
This observational study aims to investigate healthy cortical and subcortical neural processes involved in generating intrinsic alpha oscillations during induction of general anesthesia with propofol. To do this, the investigators have designed a simultaneous electroencephalogram (EEG)- MRI (functional MRI and Spectroscopy) experiment with a visual stimulation paradigm that addresses the subject's specific intrinsic alpha rhythm during anesthesia and wakefulness. The main question it aims to answer is: could the investigators address the alpha oscillation system of the healthy brain with external stimulation during anesthesia? This experiment could lead to a better understanding of the mechanisms underlying the generation of alpha oscillations. It could open new doors to diagnostic and treatment options for diseases where alpha oscillations, such as post-operative delirium, seem to be affected.
Determining the efficacy of the BIS monitor in monitoring deep hypnotic states as well as intra- and post-operative outcomes in neurosurgery patients
Our study aimed to compare the manual placement, direct laryngoscopy and video laryngoscopy assisted placement techniques of LMA Proseal, a new generation laryngeal mask (LMA), and to find an effective placement technique that does not allow airway leakage in one go.
The aim of the study is to assess the efficacy of adding a pre-emptive combined bilateral infraorbital and infratrochlear nerve blocks with bupivacaine 0.25% in decreasing intraoperative and postoperative analgesics consumption and maintaining intraoperative hemodynamic stability during nasal surgeries.
Remimazolam has demonstrated the potential as a valuable medication for procedural sedation and general anesthesia. However, half effective dose of remimazolam required to prevent cardiovascular response to tracheal intubation when combined with fentanyl in pediatric patients is still unknown.
