Filter by:This study evaluates difference of the endotracheal tube cuff pressure between a tapered- versus a cylindrical- shaped cuff after changing from neutral to hyperextension of neck. Fifty patients undergoing thyroidectomy are randomly allocated into two groups (tapered- and cylindrical-shaped cuff). Endotracheal tube cuff pressure is initially set at 20 cmH20 in the supine neutral position and is measured after the change to the neck extension.
Parathyroid glands are involved in calcium metabolism and their damage during neck surgery results in 'hypoparathyroidism', a condition characterized by 'low blood calcium' levels; this is associated with significant short and long term morbidity. There are four parathyroid glands in the neck which can vary in size and location. They can be mistaken for lymph nodes, fat or thyroid nodules. A normal parathyroid gland is the size of a small pea and is often difficult to recognize during surgery; making it susceptible to inadvertent injury or removal. Thyroid and parathyroid surgery are commonly performed in the UK. Prompt and accurate identification of parathyroid tissue during surgery reduces the likelihood of hypoparathyroidism. However, this complication is still common. Research exploring the use of intraoperative technologies to enable early identification and preservation of normal parathyroid glands during surgery is ongoing. Electrical impedance spectroscopy (EIS) is one such technology. ZedScanTM is a handheld device that measures electrical impedance of tissues. It is currently used as a adjunct during colposcopy in cervical cancer screening. The device has a CE mark for this purpose and is safe to use in humans. We have already demonstrated that electrical impedance spectroscopy can detect differences in cellular structure and differentiate between tissues in the rabbit neck. We now aim to demonstrate the feasibility of using this technology (ZedScanTM) in humans. This has potential to be used in thyroid and parathyroid surgery to differentiate parathyroid glands from other structures; thereby decreasing their damage and the risk of post surgical hypothyroidism.
The scientific interest of this study is to improve post-operative comfort in patients after thyroid surgery using simple, inexpensive techniques. The investigator expects that local applications of ice or cortisone aerosols will reduce swallowing discomfort and control post-operative pain (POP). The investigator hopes that local cryotherapy will decrease post-operative oedema (vasoconstriction) and the volume of liquid drained (action on the serous fluid at the site of the thyroidectomy).
The primary purpose of this study will be to determine whether the proposed study protocol will allow for reliable detection of the human Laryngeal evoked brainstem responses (LEBR). Laryngeal evoked brain stem responses will be recorded from five test subjects under general anesthesia in the operating room with the assistance of an electrophysiologist with expertise in evoked potentials. Once the feasibility of obtaining tracings are established on the first few subjects, responses will be recorded from other test subjects with the aim of determining the optimal placement of stimulating electrodes and detection leads necessary to elicit an adequate response. The effect of varying the stimulus intensity will also be studied. Once parameters for testing have been standardized, normative configurations for the laryngeal evoked brainstem response tracings can be determined by patients both in the office setting and in the operating room.
The purpose of this study is to compare the therapeutic effects between the axillary bilateral-breast approach (ABBA) and bilateral axillo-breast approach (BABA) for robotic thyroidectomy.To explore the efficacy, safety, cosmetic results and clinical value by the two approaches.
Thyroid surgery is a quite painful procedure performed in a sensitive skin area of the human body. Unless pain is treated adequately thyroid surgery may cause severe postoperative pain and discomfort for the patients. a2-Agonists are sympatholytic and centrally acting antihypertensive agents. In addition to their hypotensive effect, a2-agonists are also used in anesthetic practice for their sedative and analgesic effects. Tizanidine is a centrally acting a2-agonist with muscle relaxant, sedative and anxiolytic properties. This drug is widely used for the treatment of spasticity and has recently been used to treat musculoskeletal pain conditions. Ultrasound (US) guidance during regional anesthesia practices has been a revolutionary advancement to improve success and safety of regional anesthesia. Analgesic effect of US guidance superficial cervical plexus block (SCPB) in patients undergoing thyroid surgery has not been reported yet. The aim of this study was to evaluate the analgesic effect of preemptive oral single dose tizanidine and US guidance SCPB in patients undergoing elective thyroid surgery. The investigators hypothesis that: Tizanidine and US guided SCPB can reduce the pain scores, analgesic consumption, analgesic related side effects.
Patients underwent thyroidectomy filled an computer or paper based QoL questionnaire before and after operation.
Patients undergoing thyroidectomy are suffering not only surgical wound pain but posterior neck pain because of neck extension position during the surgery. However, there has been little attention of posterior neck pain. Nefopam and Propacetamol have different pharmacodynamics and been used for postoperative pain control in thyroidectomy patients. The aim of this study is evaluation of combination effect of Nefopam and Propacetamol for acute wound pain, posterior neck pain and chronic pain after thyroidectomy.
This is a single-blinded randomized controlled trial to evaluate the effectiveness of Arista hemostatic matrix powder (Arista® AH, C. R. Bard, Inc. Davol, Warwick, RI) in reducing drainage output after total thyroidectomy with and without lateral neck dissections. Increased drainage in total thyroidectomy and neck dissection wound beds can lead to seroma formation with possible secondary infection, delayed hospital discharge, and additional home care needs for drain care. Arista is an inert plant based absorbable surgical hemostatic powder that can be easily applied to broad surgical fields to reduce bleeding and seroma rates. Therefore, its application to thyroidectomy and neck dissection wound beds may bear significant potential benefit.
Intra operative Nerve Monitoring ( IONM ) is rapidly becoming the standard of care for thyroid surgery to prevent injury to the recurrent laryngeal nerve. However the laryngo tracheal reflexes need to be adequately suppressed to permit proper utilization of intra operative nerve monitoring. Increasing the depth of anesthesia to achieve this often leads to side effects. Intravenous lidocaine infusion has been shown to be effective in blunting these reflexes. The planned study intends to look at the efficacy of intravenous lidocaine infusion in decreasing the amount of anesthesia medications needed to suppress the reflexes. Also the study looks at the analgesic and anti emetic properties of intravenous lidocaine infusion post operatively by measuring these outcomes. The study is designed as a double blinded randomized controlled trial with 30 subjects in the group who will receive intravenous lidocaine during surgery and 30 subjects in the group who will receive placebo. Blunting of the laryngo tracheal reflexes intra operatively will be recorded as the primary outcome. The amount of anesthesia medications, the post operative patient comfort level, pain control, usage of narcotic pain medications, nausea, vomiting will be recorded as secondary outcomes.
