Filter by:The purpose of this study is the investigation of whether adding lidocaine to hyperbaric bupivacaine could decrease the duration of bupivacaine spinal block and provide shorter recovery and discharge times than local infiltration anesthesia in outpatient herniorrhaphy procedures.
Data on quality of clinical anesthesia are important for the improvement of both quality and patient safety in this field. Routine quality data are often collected by professionals busy with patient care. This study examines the reliability of routinely collected quality data by comparing the electronic anesthesia record with the respective reports on quality-indicating events, i.e. whether events during the anesthetic (e.g., drop of blood pressure, irregular heart rhythm, and others) were actually reported or not. Additionally, interviews with reporting staff (physicians and nurses) are performed to gain insight in possible obstacles to reporting during the working process.
For effective anesthesia and interventional pain treatments, correct needle placement is crucial. Currently used methods to guide needle placement and confirm the actual treatment location before injection of the medication include: image-guidance, loss-of-resistance, and electrical stimulation. However, accuracy of needle placement could be improved if information would be available that would complement the current methods. We have developed the so-called "photonic needle" technology based on optical spectroscopy that has the potential to provide such complementary information. This study is an observational study in a limited number of patients. A common ultrasound-guided regional anesthesia procedure has been selected, during which data will be acquired with the photonic needles at a number of points along the needle trajectory that allow for confirmation by imaging. Rationale for this study is to investigate the potential of the technology to discriminate tissues that are relevant to distinguish during the procedure.
The primary objective of this study is to characterize the safety, and efficacy of Dexmedetomidine (DEX) administered as an intravenous (IV) loading dose followed by a continuous IV infusion in preterm subjects, ages ≥ 28 weeks through < 36 weeks gestational age.
Hypotension is a recognized frequent complication of induction of anesthesia. The intent of this research is to determine the incidence of hypotension in patients receiving anesthetic induction with propofol. This investigation seeks to examine how normal clinical practice or a "real world" understanding of the usual response to propofol affects hemodynamics without isolating or standardizing other variables. The current research concerns hypotension in normal clinical practice where variability exists. This project aims to gather information and data in an attempt to form a foundation upon which each of the other variables affecting blood pressure may be subsequently assessed.
The aims of the present study are: 1. To evaluate the effect of the induction of anaesthesia and paralysis in terms of changes in oscillatory mechanics parameters 2. To evaluate the mechanical properties of the respiratory system in terms of input and transfer oscillatory impedance in response to PEEP changes
Study of time usage of anesthesia team inside the main operating room compares between 2 groups of - Performing regional anesthesia inside the operating room - Performing regional anesthesia in the block room Study purpose: How much will the investigators save time in the main operating room if we perform the regional anesthesia in the block room?
This study is designed to compare the effects of two bolus doses of intravenous remifentanil given prior to the emergence of anesthesia: - on the incidence of perioperative coughing - on the time needed for the emergence of a desflurane-based anesthesia - on the incidence of sore throat after extubation. The investigators hypothesis is that the use of a higher remifentanil bolus dose (0.5 mcg/kg) given prior to emergence of a desflurane-based anesthesia will reduce the incidence of perioperative coughing when compared to a lower dose of remifentanil (0.25 mcg/kg).
The use of ultrasonography as an adjunct to regional anesthesia has significantly increased in recent years. Brachial plexus blockade by an axillary approach is amenable to the use of ultrasound guidance. Real time sonography of nerve structures ensures an optimal distribution of the block solution. When compared to other methods of nerve localization, sonography decreases: failure rate procedure time and the onset time for blockade. Furthermore, the use of ultrasound for peripheral nerve blockade demonstrates decreased procedure related complications such as nerve injury and unintentional vascular puncture. Traditional axillary block techniques relying on surface anatomical landmarks require large volumes of local anesthetic, generally 40mL and greater. Utilizing the increased accuracy offered by ultrasound, some studies have shown that low volumes of local anesthetic can yield successful axillary plexus blockade. Therefore, the tradition of using large volumes of local anesthetic for axillary blocks, even without ultrasound, may not be warranted. Although recent investigations support using a low volume of local anesthetic for brachial plexus blockade, there is a lack of outcome data from blinded randomised trials. The primary objective of this study was to evaluate 2 different volumes of local anesthetic for axillary blockade: 1) 20mL or 2) 30 mL. For the 2 different volumes used in this study, a 1.5% solution of mepivacaine was chosen due to its widespread clinical use in axillary blocks, which is secondary to: rapid onset of action, intermediate duration of effect, and relative low cost. The primary outcome was block success rate for outpatients undergoing distal upper limb surgery. Secondary objectives included comparing the 2 volumes with respect to: time required to perform the block, and onset of sensory and motor blockade.
The purpose of this study is to evaluate the efficacy of and recommended dosing regimen for unilateral administration of Kovacaine Mist in inducing pulpal anesthesia of the maxillary teeth for dental procedures.
