Continuous Lidocaine Infusion in Thyroid Surgery Using Intraoperative Neurophysiological Monitoring

Thyroid surgery is a common procedure for the treatment of thyroid tumors, nodules and other related lesions. During this procedure, intraoperative neurophysiological monitoring is used to protect the recurrent laryngeal nerves. For the nerve monitor to work properly, a reduced muscle relaxant dosage is indicated. The main objectives of the anesthesiologist are maintaining deep sedation, analgesia and immobilization during surgery, as well as enhance post-operative recovery. Reduced muscle relaxant use during surgery poses the risk of inadequate immobilization during the operation, which may result in serious surgical complications. Intravenous bolus administration of fentanyl is currently the most popular method to maintain the depth of anesthesia during such operations. However, the side effects include intraoperative hypotension, bradycardia, and postoperative nausea and vomiting. The ultra-short acting remifentanil may be appropriate for inhibiting the bucking reflex during surgery, but the risk of opioid-induced hyperalgesia and opioid tolerance after surgery has been reported. In recent studies, intravenous lidocaine has been shown to increase the depth of anesthesia and provide analgesia, with no muscle relaxing effect. The aim of this study is to examine the depth of anesthesia, surgical operating conditions, and the recovery profile with the use of a continuous lidocaine infusion.

Impact Of Thyroid Dysfunction on Liver Function Tests

This study aims to evaluate the effect of thyroid dysfunction on liver function tests.

The Effective Blood Concentration of Ciprofol

1. Eligible patients were selected and enrolled in the study. 2. General anesthesia was induced using ciprofol in all participants, with standardized evaluation of consciousness levels during induction. 3. The patients' pain and cognition are followed up after surgery.

Dysphagia After Thyroidectomy

The goal of this observational study is to develop a questionnaire for measuring swallowing and throat discomfort symptoms in patients with goiter or thyroidectomy, which complies with the model of Rasch and which satisfies the fundamental measurement axioms (e.g., unidimensionality, linearity, generalizability). Developing a scale with such characteristics would provide clinicians and researchers with a reliable tool for assessing the impact of goiter and for measuring the outcomes after surgery. Also, the study will assess the psychological impact of goiter and thyroidectomy, as well as the characteristics of the surgical scar after thyroidectomy. The questionnaire will be developed in the first phase of the study. Items and response categories will be identified through interviews performed with patients affected by goiter or after thyroidectomy. In the following phases of the study, the questionnaire will be administered to patients before and after thyroidectomy.

Pressure-enabled Retrograde Occlusive Therapy With Embolization for Control of Thyroid Disease (PROTECT Registry): A Multicenter Registry

Multi-center registry study to evaluate disease-related quality of life outcomes of thyroid embolization via pressure-enabled delivery (PED-TAE). Additional technical success data on parenchymal volume reduction, thyroid function tests changes and post-procedural complications will be recorded. Data will be collected for patients who have undergone PED-TAE using the TriNav Infusion System at participating sites. The registry study will include up to 10 sites, with Sarasota Memorial Health Care System acting as the lead site responsible for maintaining and monitoring the study database.

Identification of Nerves Using Fluorescein Sodium

The purpose of this study is to see if there is benefit in using an IV contrast (sodium fluorescein) to identify nerves during head and neck surgery.

Effect of Nutrition Education on the Quality of Life, Chronic Disease Adaptation in Patients With Thyroid Dysfunction

This thesis study is designed to examine the effects of nutrition education provided to individuals with thyroid dysfunction on their quality of life and adaptation to the disease. The data will be collected using the Descriptive Characteristics Form, the Nutrition Attitude Scale, the Quality of Life Scale for Thyroid Patients (ThyPRO), and the Chronic Illness Adherence Scale. The Body Mass Index (BMI) of participating patients will be calculated by the researcher based on measured height and weight. Laboratory values including TSH, free T4, and free T3 will be obtained from the patients' medical records on the day of assessment. Data collection will be conducted in two phases. The study population will consist of all patients diagnosed with thyroid dysfunction who present to Dr. Burhan Nalbantoğlu Hospital. Using the G\*Power 3.1.9.2 software, the required sample size was calculated prior to data collection with a 95% confidence level. For correlation analysis, an alpha value of 0.05, an effect size of 0.455, and a statistical power of 95% were assumed, resulting in a minimum sample size of 56 participants (30 per group). Accounting for potential data loss, a total of 60 patients (30 per group) are planned to be included in the sample.

ThyMoves: Screening and Exercise to Improve Muscle, Enhance Quality of Life, and Reduce Fall Risk in Thyroid Disease

Objectives: This study aims to assess health-related quality of life (QoL) in adults with thyroid hormone disorders and identify modifiable factors to improve QoL in patients with Hashimoto's thyroiditis (HT) and multinodular toxic goiter (MNTG) through an exercise intervention. Primary Outcome: 1\. Assess the impact of a tailored exercise program on health-related QoL in patients with HT and MNTG using the ThyPRO questionnaire. Secondary Outcomes: 1. Evaluate the need for a screening tool to identify thyroid patients with reduced health-related QoL despite being euthyroid. 2. Assess the impact of the exercise intervention on body composition, strength, and balance function in HT and MNTG patients. Methods: The study is a combined cross-sectional survey and randomized controlled trial into the health related QoL in patients diagnosed with thyroid hormone disease. The cross-sectional survey will assess the overall health-related QoL in patients diagnosed with thyroid hormone disease, and help identify eligible participants for the subsequent RCT. The RCT will evaluate the efficacy of a comprehensive screening and exercise intervention in patients ≥ 65 years diagnosed with HT or MNTG, experiencing reduced health-related QoL. Participants: The aim is to recruit 74 patients with HT and 74 patients with MNTG, including 50 participants from each group with reduced health-related QoL (defined in this study as ThyPRO score ≥ 30) and 24 with good health-related QoL (ThyPRO score ≤ 20)

Autofluorescence and Indocyanine Green to Avoid Hypocalcemia After Thyroidectomy

* Hypoparathyroidism (and the resulting hypocalcemia) remains the most common morbidity after a total thyroidectomy. * The identification and preservation of parathyroid glands during neck surgery has always been challenging but is crucial to avoid postoperative hypocalcemia. * Recently, the specific autofluorescent characteristics of endogenous fluorophores in the parathyroid tissue have been used to detect and confirm parathyroid glands during thyroid surgery. * Injecting indocyanine green and using its fluorescent characteristics has the advantage of adding information about the vascular supply of the parathyroid glands. * This randomized clinical trial aims to investigate whether using autofluorescence and indocyanine green during thyroid surgery can predict or prevent postoperative hypocalcemia.
