Filter by:Orthopedic interventions under spinal anesthesia is considered a common practice in elderly patients undergo surgery, and may be associated with lower risks of death, delirium,and major medical complications . Spinal anesthesia can cause disastrous hemodynamical changes in the form of hypotension and bradycardia in elderly patients due to limited physiological reserve and presence of systemic illness . The degree of hypotension is proportional to the extent of sympathetic blockade. thus unilateral Spinal anesthesia described by Tanasichuk et AL. was used aiming to minimize these hymodynamical changes compared to bilateral block by restricting the extent of sympathetic blockade. Bupivacaine has been used in spinal anaesthesia in orthodecic surgeries . It provides a short motor block onset time with a long motor block duration . If bupivacaine is used, the main disadvantage is the significant inter-individual variability with clinically significant differences in onset time, dermatomal spread and motor block duration . Prilocaine is a local anaesthetic agent that belongs to the same family as bupivacaine. In the last decade and with the development of day surgery, prilocaine 2% has become more commonly used for orthopaedic surgical procedures . Prilocaine induces a shorter motor block with less urinary retention, which better facilitates enhanced recovery after surgery . Usually, doses administered in spinal anaesthesia vary from 20 to 80 mg . Given the intermediate motor block duration, The aim of this study To compare between Unilateral low dose spinal anesthesia using bupivacaine versus prilocaine regarding hemodynamical stability and safety in below knee orthopedic surgeries in elderly people.
The CONNECT: "Developing a learning COmmunity to increase eNgagemeNt and Enrollment in cardiovascular Clinical Trials" is comprehensive, participant-centered learning community that provides tailored education on cardiovascular (CV) health and research participation; connects community members to CV-related research; and disseminates CV-related study findings. The overreaching goal of CONNECT is to improve participation of underrepresented communities in CV research, including as women, Black adults, and Latino adults, through increasing participants' clinical trial awareness, trust in biomedical research, and willingness to participate in clinical trials. CONNECT will use digital and community-engaged approaches to identify and recruit 1000 adults with cardiovascular disease or a cardiovascular disease risk factor to join CONNECT. Participants who join CONNECT will receive tailored educational information on CV health and research participation via text message. Participants will also have the opportunity to be matched to ongoing CV research studies based on basic demographic information and areas of interest. The educational information will be sent to participants for 12 months. The investigators hypothesize that CONNECT will increase participants' clinical trial awareness, trust, and willingness to participate in clinical trials and that the proportion of Black and Latin adults and women enrolled in trials that partner with CONNECT will be higher following the use of CONNECT for recruitment.
The primary research objective is to examine how uncertainty towards a new medical treatment changes in patients when a partner (can be any close other, i.e. romantic partner, family member, or a close friend) supports the new treatment choice and is willing to be involved in the patient's treatment. I hypothesize that when the patients know that their partner supports uptake of the new medical treatment and will physically accompany them to the visit, patients will (1) experience lower levels of uncertainty and (2) report a higher likelihood of participating in a new treatment in the future, as compared to patients who face the decision about the new treatment alone.
This pilot study aims to examine the feasibility of recruiting depressed adolescents to examine changes in emotional processing and in neural responses to emotional stimuli after one session of rTMS (which is followed by an open-label phase of 4 weeks active rTMS).
There are ~85,000 lung cancer patients (LCPs) in the UK; yet only around 8% were recruited into clinical trials in 2021/22. LCPs need opportunities to take part in clinical trials to access new treatments, increasing their quality of life, treatment choices and life expectancy. Discussions with nurses can help patients make better treatment decisions, improving experiences of care. However, research has shown that lung cancer nurses (LCNs) often feel unable to discuss participation in trials with patients due to lack of knowledge, confidence, time and training. This study aims to develop and test a research recruitment tool for LCNs, to support LCPs to enter clinical trials. Objectives include to: - Explore reasons for low uptake of LCPs into clinical trials - Develop a tool for LCNs to talk to patients about clinical trials - Test whether the tool improves the number and quality of discussions nurses have with LCPs about clinical trials The study has four phases: Phase 1: A literature review will identify problems that make clinical trial uptake difficult for LCPs, carers and clinicians Phase 2: Six group discussions with LCNs, patients and carers will explore issues that create potential barriers for patients taking part in clinical trials. The groups will take place online, last approximately one hour and be recorded. Phase 3: Part 1&2 findings will help us develop a LCN research recruitment tool. The tool will contain information on how nurses obtain information about LC clinical trials, research teams, communication issues, practical issues and how to reach LCPs. Phase 4: The research recruitment tool will be tested in four UK NHS hospitals. A survey will identify any changes in nurses' clinical trials awareness and confidence before and after using the tool. Interviews with LCNs, patients and carers will explore their views on the tool, clinical trials participation and experiences of care.
Respiratory failure associated with Covid-19 can be expressed as acute respiratory distress syndrome (ARDS), which is an acute inflammatory lung injury,which generally requires the use of invasive mechanical ventilation (MV). There are inconclusive results regarding the potential lung recruitment in ARDS. At the lung level, the relationship between lung volume and pressure can be graphed through a pressure/volume (P/V) curve. In this curve, hysteresis (H) can be evaluated, which is the amount of energy generated during inspiration that is not recovered during expiration. H is related to recruitment, assuming that the greater H the greater the alveolar recruitment. For this reason, the objective of this study is the measurement of H as a way to assess the lung recruitment capacity, in patients with ARDS and in patients with Covid-19 who develop ARDS (ARDS- Covid)
This study will examine the context of making high quality dietary choices among Black adults with hypertension. Secondly, this study will also investigate what Black adults need or desire to participate in a digital intervention to improve dietary quality by adopting the DASH eating pattern.
This study aims to demonstrate the effects of automatic recruitment maneuver on peroperative lung mechanics of obese patients undergoing laparoscopic abdominal surgery. 128 obese patients undergoing abdominal laparoscopic surgery are randomly going to be assigned to automatic recruitment maneuver group and no recruitment maneuver group (control group). Both groups are going to be taken to the operating table. Electrocardiography (ECG), noninvasive blood pressure (NIBP), pulse oximeter and peripheral oxygen saturation (SpO2) and post-intubation end-tidal carbon dioxide (EtCO2) and train of four (TOF) monitoring will be performed. Then, general anesthesia induction procedure will be started. Following intubation, patients will be ventilated according to the ideal weight within the scope of intraoperative protective ventilation strategy and in pressure-controlled ventilation (PCV) mode. Then, automatic recruitment maneuver will be applied to the recruitment group twice, after insufflation and desufflation. It will not be applied to the control group. During recruitment maneuver, PEEP (Positive end-expiratory pressure), where dynamic compliance is measured highest, will be the ideal PEEP (Positive end-expiratory pressure) for the patient, and PEEP (Positive end-expiratory pressure) will be adjusted at this value after recruitment. If MAP (mean arterial pressure) is <60 mmHg during the maneuver, the maneuver will be terminated and these patients will be excluded from the study. Respiratory mechanics for both groups (peak pressure, plateau pressure, driver pressure, static compliance, dynamic compliance, EtCO2) and hemodynamic parameters (heart peak, mean arterial pressure, SpO2) at 5 different times (T1: post intubation; T2 : after insufflation; T3: 5 minutes after insufflation / after the first recruitment maneuver; T4: after desufflation; T5: 5 minutes after desufflation / after the second recruitment maneuver) will be recorded. Throughout the surgery, insufflation pressure will be kept as 10-13 cmH20. At the end of the surgery, the anesthesia maintenance of all patients will be terminated and the routine wake-up phase will be initiated. Creatinine values and hourly urine outputs of all patients routinely monitored at the postoperative 24th hour will be recorded on the case follow-up form.
In trauma patients, the incidence of pulmonary contusion is frequent. Recruit maneuver using lung ultrasound could be improve oxygenation in trauma populatioin, howevere, there is no previous study. The aim of this study is evaluation of the efficacy of lung recruitment using ultrasound in perioperative period in trauma patients.
The investigators want to test the hypothesis that the addition of a recruitment manoeuvre to a low pressure pneumoperitoneum will lead to an additional reduction in postoperative pain. Therefore the investigators will conduct a prospective randomized controlled, single blind trial.
