Filter by:In this exploratory qualitative study with a hermeneutic phenomenological approach, we will describe and understand the experience of treatment and hospitalization in hospitalized people suffering from stroke, multiple sclerosis, Parkinson's disease and patients post-neurosurgery for oncological causes. Patients will be interviewed in a semi-structured manner and sampling will take place for each of the pathology groups according to the saturation method.
The goal of this clinical trial is to to evaluate the efficacy of lidocaine sprayed at the laryngeal inlet combined with the endotracheal tube cuff compare with intravenous lidocaine on the hemodynamic response to laryngoscopy and intubation in patients undergoing elective neurological procedures during general anesthesia with total intravenous technique. The main question it aims to answer is: - Does topical lidocaine sprayed at the laryngeal inlet combined with the endotracheal tube cuff have more effect on stabilizing hemodynamic responses to laryngoscopy and intubation than intravenous lidocaine, in neurosurgical patients who undergo general anesthesia with total intravenous technique? Participants will be recruited and randomized to receive either lidocaine spray (Group SL) or intravenous lidocaine (group IL) to blunt hemodynamic response to laryngoscopy and intubation.
A prospective, open-label, single center, controlled trial. 44 patients that underwent neurosurgery or presented meningitis signs, for whom Clindamycin add-on therapy to assess its effect on neurological complication in relation to Neuron-specific enolase (NSE) and Neurotensin biomarkers levels.
Respiratory muscle dysfunction may contribute to the development of postoperative pulmonary complications. However, it prevalence in patients receiving neurosurgery is largely unknown. Therefore, in present study, respiratory muscle function (measured by the ultrasound) and their correlation with the post-operative pulmonary complications will be analyzed.
The objective of this observational study is to examine the impact of augmented arterial pressure during the hemostatic phase of elective supratentorial neurosurgery. The primary inquiries it seeks to address are as follows: 1. Does an increase in systolic arterial pressure prompt a hemostatic maneuver by the neurosurgeon, and does the concomitant mean arterial pressure value influence the frequency of such interventions? 2. How often do postoperative intracranial hemorrhages occur, and how severe are they in relation to the achieved mean arterial pressure value? Participants will be enrolled during the preoperative evaluation, where their arterial pressure values, medical histories, and medication statuses will be recorded. Throughout the induction and maintenance of anesthesia, we will monitor their blood pressure values and document any instances of hypotension or hypertension. During the hemostatic phase, we will elevate the arterial pressure using noradrenaline by up to 10 mmHg above the recorded pressure measured at the inpatient clinic. Subsequently, we will inquire whether the neurosurgeon had to employ any additional hemostatic maneuvers following the increase in arterial pressure. The arterial pressure values will be recorded at the end of the surgery, and the first postoperative CT scan will be examined to identify any cases of intracranial hemorrhage.
Validation of Clinical Prediction Model for Venous Thromboembolism Following Neurosurgery: A Multicenter, Prospective, and Cohort Study
The goal of this pilot clinical trial is to test the feasibility of conducting a randomized controlled trial that will examine the use of ropivacaine in the spinal anesthesia for patients undergoing elective 1- or 2-level lower spine surgery. This study aims to: - Determine the rates of eligibility, recruitment, consent, and attrition - Determine the acceptability among patients, surgeons, anesthesiologists, and nurses of doing spine surgery under spinal anesthesia - Gather preliminary data on outcomes relevant to a future dose-finding study Participants will be randomized to one of three treatment groups: - General anesthesia with endotracheal tube - Spinal anesthesia with bupivacaine - Spinal anesthesia with ropivacaine
The purpose of this study is to obtain images of brain tumours during surgery using a new type of surgical camera. The study will assess how the information obtained from the images during surgery matches the removed tissue. Data will also be used to develop the system's key computer-processing features. This will enable real-time information to be given to the surgeon whilst they are performing the procedure and has the potential to make neurosurgery safer and more precise.
Brain surgery operations include brain tumour removal and blood vessel procedures. Each year in the UK, approximately 70,500 patients are diagnosed with a brain tumour, 5,000 of whom undergo surgery. Approximately 1,000 patients undergo blood vessel brain surgery. Brain tumour surgery involves removing as much of the tumour as safely as possible. If all tumour is removed, patients have significantly better outcomes and live longer. However, even with the best hands and the most modern technology currently available, it is often not possible to reliably identify tumour during surgery. Moreover, nerves and blood vessels cannot be reliably identified either during surgery. Yet, they need to be preserved to avoid brain damage. Due to this uncertainty and the need to balance risks, tumour is often left behind. Today, close to 30% of brain tumour patients require repeat surgery owing to tumour left behind during their first surgery. Further surgeries are more difficult, pose additional patient risks and lead to increased healthcare costs with often poor patient outcomes. Newly developed camera systems have the potential to enhance the surgeon's vision to reliably identify tumour and healthy brain structures. Hyperspectral imaging (HSI) is one of the most promising of such technologies. Its core ability is to provide very detailed and rich information that is invisible to the human eye. HSI has demonstrated the potential to provide crucial, but currently unavailable, information about tumour and critical brain structures during surgery. However, HSI data is very complex and requires advanced computer-processing for its interpretation. In this project, we will use a HSI imaging system to record data in 81 patient undergoing brain including 63 patients with brain tumours and 18 patients suffering from brain vessel abnormalities. Using this data we will develop key computer-processing features to enable real-time image interpretation.
The proposed study intends to evaluate incidence of postoperative pain after neurosurgery. This study is likely to help in understanding of the magnitude of this problem in our country and inform about possible predictors which will help institute pre-emptive interventions to mitigate modifiable risk factors of pain after neurosurgery.
