Filter by:Dexmedetomidine is a highly selective α2-agonist with hypnotic, analgesic, and anxiolytic properties. Despite off-label administration, dexmedetomidine has found a niche in critically ill mechanically ventilated neonates and infants because of its minimal effects on respiratory function at sedative doses, facilitating early extubation and fast-track postoperative care.
Controversies exist about the use of propofol in sedation of patients for cataract surgery. This prospective randomised double-blind study evaluates the efficacy of patient-controlled sedation compared with placebo using the same device.
Background: This study was designed to investigate the effect of sedation on the occurrence of maternal hypotension in preoperatively anxious parturients undergoing urgent category-1 Cesarean section (C/S) under spinal anesthesia. Methods: After institutional ethics committee approval, prospectively collected data of 1824 parturients undergoing C/S were reviewed. Parturients with high preoperative anxiety scores (visual analogue scale for anxiety (VAS-A)≥70) undergoing C/S under spinal anesthesia with thiopental (Group S=49) and without any other type of sedation (Group NS=53) were included in the analysis. Hemodynamic parameters were documented and maximum systolic arterial pressure (SAP) reductions from the baseline after spinal anesthesia were calculated. Incidences of hypotension (SAP≥30% decrease from baseline or <100 mmHg) and bradycardia (HR<55 beats/min), and related-ephedrine and -atropine requirements were noted. Our primary endpoint was to compare the maximum SAP reductions from the baseline values in Groups S and NS. Secondary endpoints were incidences of hypotension and bradycardia, required ephedrine and atropine doses, newborn Apgar scores at 1st and 5th min.
Object: To explore the mechanism of the electro-acupuncture (EA) induced sedation effect in general anaesthesia through investigating the role of the Benzodiazepines-GABA system. Method: 80 patients undergoing abdominal surgery were randomly divided into four groups (n=20): C group (propofol only group), F group (propofol + flumazenil group), EA group (propofol + electro-acupuncture group), and EA+F group (propofol + electro-acupuncture + flumazenil group). Before induction, acupuncture needles were inserted at the points of Zusanli (ST 36) and Neiguan (PC 6) bilaterally to elicit"DeQi". Target-controlled infusion (TCI) of propofol was used for the induction and maintenance of anaesthesia. After 15minutes, equilibrium of Narcotrend Index (NT index) was achieved, patients were then assigned to receive different interventions. In EA group and EA+F group, patients received EA for 30 minutes under general anaesthesia, and flumazenil with the dosage of 0.1mg/kg was added in the latter at the end of EA. In C group and F group, patients didn't receive EA, and flumazenil with the dosage of 0.1mg/kg was administered in F Group at the same time point with EA+F group. HR, MAP and NT index were recorded at different time points up to 30 minutes after the end of EA.
The interaction of analgesia and sedation ot their effect on the prognosis of surgical patients still need to be elucidated.Currently, how to optimize intra-operative Analgesia and sedation to improve the prognosis of surgical patients is still a mystery.Intra-operative nerve block provided regional analgesia of the operated knee, which reduced the dosages of sedatives and analgesics.Based on a pilot study,the investigators found a decrease of post-operative adverse composite outcomes with the use of continuous femoral nerve block (2% versus 7%) ,therefore, the investigators postulate that general analgesia with lighter sedation in combination with peripheral nerve block could reduce the post-operative morbidity compared with deeper sedation.This randomized controlled trial is designed to test this hypothesis in patients receiving unilateral knee arthroplasty.
The purpose of this study is to estimate the hypothesized benefit of sedation interruption protocol on mechanical ventilation duration and PICU length of stay. The study will evaluate recruitment rates, and adherence rates of such protocol.
The investigators' clinical practice makes use of oral clonidine as a means of transitioning from intravenous dexmedetomidine following prolonged infusions (more than 3-5 days). Although this is common clinical practice, there is limited clinical data to demonstrate the efficacy of this technique and to provide clonidine dosing guidelines. The purpose of this study is to retrospectively review the investigators' experience with the use of oral clonidine to prevent withdrawal following the prolonged administration of dexmedetomidine.
Midazolam is often given before surgery to sedate a patient before anesthesia is given. Children are often given a small dose either by mouth or squirted into the nose. Children will often spit out the oral midazolam, making it difficult to know how much medicine, if any, they have received. Giving midazolam into the nose is more reliable, but children may complain of pain, stinging, and may become upset due to the discomfort. Nosebleeds may also occur when midazolam is squirted alone into the nose. The purpose of this study is to see if adding a numbing medicine, xylocaine, to the nasal midazolam makes giving the midazolam easier and more comfortable without affecting how the midazolam works as a sedative. This is follow up to the pilot study, Project # 994. This will expand the previous study, with additional participants and revised xylocaine concentration
To evaluate the effect and safety of noninvasive ventilation assisted interventional bronchoscopy for hypoxemia patients with central airway stenosis. With the sedation and analgesia, noninvasive ventilation assisted interventional bronchoscopy for hypoxemia patients with central airway stenosis is safe and effective, carries high satisfaction rate.
Flexible bronchoscopy almost always requires sedation to be successful. In order to increase the availability of propofol for sedation, non-anaesthesiologist administered propofol sedation has been suggested as an alternative to traditional midazolam/opioid sedation or the general anaesthesia provided by anaesthesiologists. Hypothesis: Patients undergoing flexible bronchoscopy prefers non-anaesthesiologist administered sedation with propofol as opposed to non-anaesthesiologist administered sedation with midazolam and fentanyl. Propofol sedation is as safe as midazolam and fentanyl sedation.
