Filter by:Noise in the operating room is common and often unavoidable, but there is mixed evidence of its impact. Previous research has suggested that excessive noise at the time when a patient is being 'put to sleep' may lead to care teams missing changes in monitors, having difficulties focusing or increasing stress. However, it is unknown ifs noise at this time affects the patient's satisfaction with the overall surgical experience. The investigators are conducting a survey study to evaluate patients' and anesthesiologists' overall satisfaction at the time of induction, before and after an education program promoting reducing noise in the Operating Room. Study Purpose: The purpose of this study is to investigate how noise levels that the time of induction in the OR (operating room) effect patient and anesthesiologists' satisfaction with the overall surgical experience. Hypothesis: The null hypothesis is that there is no improvement in patient satisfaction with the reduction of noise at the time of induction. Study Population: The Investigators will be including two study populations: patients age 19 or older undergoing elective, non-cardiac surgery with general anesthesia as the primary mode of anesthesia, and; Anesthesiologists working in these rooms. Research Method: This will be a pre/post survey study of patients and Anesthesiologists perspectives of noise in the OR. The investigators will survey participants before and after an educational intervention for OR staff.
Femoral nerve catheter for postoperative analgesia will be included in the adult patients undergoing total knee arthroplasty included in the study. These patients will be randomized to the catheter tip configuration as CEMP (closed-ended multiport catheter) group and OESP (open-ended single port catheter) group. Patient controlled analgesia device will be attached to the peripheral nerve catheter of these patients. Demographic data of the patients , the number of pushing the button the amount of bolus dose given, and the total dose given in the patient controlled anesthesia device, the need for additional analgesia and the amount, pain scores, complications will be recorded for three days postoperatively. Records will be compared statistically.
This study will compare an opioid free anesthetic, using dexmedetomidine, to a traditional opioid based anesthetic, using fentanyl, for patients undergoing cardiac surgery with regards to hemodynamic stability in the first 10 minutes after induction.
Acute appendicitis which is the most common cause of acute abdominal pain, is an acute inflammation of appendix vermiformis. Appendectomy operations can be performed as laparoscopic and open surgery. Addition of opioids to intrathecal local anesthetics to improve the quality of preoperative analgesia is an increasingly used method in recent years. The aim of this study is to compare bupivacaine-fentanyl and bupivacaine-alfentanil which are used intrathecally to create motor and sensory block. 50 volunteer patients who were diagnosed as appendicitis by laboratory tests and clinical diagnostic methods in general surgery clinic and classified as American Society of Anesthesiologists Classification I-II (ASA Class I-II) aged between 20-60 years scheduled for laparoscopic appendectomy operation, were included in this study. The patients were randomly assigned into two groups, Group I and Group II. Patients received spinal anesthesia with either 10 mg heavy bupivacaine (2 cc)+25 mcg fentanyl (0.5 cc) intrathecally (Group I, n=25) or 10 mg heavy bupivacaine (2 cc)+250 mcg alfentanil (0.5 cc) intrathecally (Group II, n=25).
Brachial plexus block is a very reliable method of regional anesthesia for the upper limb. It achieves ideal operating conditions by producing complete muscular relaxation and stable intraoperative hemodynamics.However,Local anesthetics alone have a shorter duration of postoperative analgesia. Hence,various adjuvants have been added to local anesthetics to achieve quick, dense, and prolonged block. This study assess and compare the efficacy of dexamethasone or nalbuphine as adjuvants to local anesthetics in supraclavicular brachial plexus block for upper limb surgeries.
The stapedius reflex protects the ear from the loud noise. The measurement of the intraoperative electrically evoked stapedial reflex threshold (ESRT) during pediatric cochlear implants (CIs) is used to confirm that the implant is functioning correctly and determine the maximum comfortable level . Total intravenous anesthesia (TIVA) with propofol and remifentanil is frequently used for pediatric CIs as it does not suppress the ESRT. However, high doses of remifentanil exacerbates postoperative pain and increased opioid consumption.
Objective: Determine if, by reducing the dose of propofol and increasing the time elapsed between fentanyl and propofol administration, hemodynamic response is improved. Methods: Patients were randomized into time groups (2 and 1 minute) and each subdivided into dose groups (1, 1.5 and 2 mg kg-1) obtaining six time-dose groups. After receiving 2 μg kg-1 of fentanyl, propofol was administered after the predetermined time. Time to hypnosis (BIS<60) and hemodynamic parameters at pre-induction, pre-intubation and postintubation were registered.
This international, multicentre, pragmatic, double-blind, placebo-controlled, randomised trial of TxA versus placebo will enrol 3,300 patients throughout Australia and internationally. This is an effectiveness trial - some elements of the trial are deliberately left to the perioperative clinicians' discretion in order to reflect usual practice and maximise generalisability.
The purpose of this study is to evaluate the impact of a curriculum about professionalism on stress response during a critical situation in anesthesiology residents. Residents in anesthesiology will complete a training program on professionalism during their first postgraduate year. They will go through a standardized simulated scenario where they have to manage an intra-hospital cardiorespiratory arrest and then meet the patient's family. Stress response will be assessed and compared to a control group that did not receive the training program.
Deep sedation or general anesthesia is frequently required for infant that need radiotherapy to treat malignancies. As radiation therapy usually consist of several sessions, these patients are exposure to several consecutive anesthetic exposures (e.g. for some central nervous system tumors 30 sessions of radiotherapy are required). In our center, this 30-min anesthetic exposure are with sevoflurane. Considering that repeated daily exposure to such potent drugs, as general anesthetics, may induce tolerance, it is reasonable to explore whether this phenomenon is occurring in this population. The aim of this observational study was to determine if a repeated exposure to sevoflurane is associated with the development of clinical and electroencephalographic tolerance. We will enroll 16 pediatric patients, and we will measure the time needed to appropriately place the laryngeal mask (clinical effect) and we also will compare the electroencephalographic signal under anesthesia across the different sessions (electroencephalographic effect).
