  • Perioperative Major Adverse Cardiovascular and Cerebrovascular Events Associated with Noncardiac Surgery
    Research JAMA Cardiology | Original Investigation Perioperative Major Adverse Cardiovascular and Cerebrovascular Events Associated With Noncardiac Surgery Nathaniel R. Smilowitz, MD; Navdeep Gupta, MD; Harish Ramakrishna, MD; Yu Guo, MA; Jeffrey S. Berger, MD, MS; Sripal Bangalore, MD, MHA Invited Commentary page 188 IMPORTANCE Major adverse cardiovascular and cerebrovascular events (MACCE) are a Supplemental content at significant source of perioperative morbidity and mortality following noncardiac surgery. jamacardiology.com OBJECTIVE To evaluate national trends in perioperative cardiovascular outcomes and mortality after major noncardiac surgery and to identify surgical subtypes associated with cardiovascular events using a large administrative database of United States hospital admissions. DESIGN, SETTING, PARTICIPANTS Patients who underwent major noncardiac surgery from January 2004 to December 2013 were identified using the National Inpatient Sample. MAIN OUTCOMES AND MEASURES Perioperative MACCE (primary outcome), defined as in-hospital, all-cause death, acute myocardial infarction (AMI), or acute ischemic stroke, were evaluated over time. RESULTS Among 10 581 621 hospitalizations (mean [SD] patient age, 65.74 [12.32] years; 5 975 798 female patients 56.60%]) for major noncardiac surgery, perioperative MACCE occurred in 317 479 hospitalizations (3.0%), corresponding to an annual incidence of approximately 150 000 events after applying sample weights. Major adverse cardiovascular and cerebrovascular events occurred most frequently in patients undergoing vascular (7.7%), thoracic (6.5%), and transplant surgery (6.3%). Between 2004 and 2013, the frequency of MACCE declined from 3.1% to 2.6% (P for trend <.001; adjusted odds ratio [aOR], 0.95; 95% CI, 0.94-0.97) driven by a decline in frequency of perioperative death (aOR, 0.79; 95% CI, 0.77-0.81) and AMI (aOR, 0.87; 95% CI, 0.84-0.89) but an increase in perioperative ischemic stroke from 0.52% in 2004 to 0.77% in 2013 (P for trend <.001; aOR 1.79; CI 1.73-1.86).

Abstract Background: Laryngeal carcinoma occupies the space of glottis. It may lead to difficult airway, and is prone to bleed if intubated with endotracheal tube (ETI). Intubation can also result in the possibility of tumor cultivation in the lung. Use of laryngeal mask airway (LMA) could avoid the disadvantages of endotracheal intubation, which would benefit patients undergoing partial laryngectomy. Methods: This was a randomized controlled clinical trial. Thirty adult patients scheduled to receive partial laryngectomy were enrolled. All study subjects received an ASA rating of grade III.

  • Closed Rhinoplasty: Effects and Changes on Voice - a Preliminary Report
    Topic: EuRePS Meeting 2015: best five papers Closed rhinoplasty: effects and changes on voice - a preliminary report Giuseppe Guarro, Romano Maffia, Barbara Rasile, Carmine Alfano Department of Plastic and Reconstructive Surgery, University of Perugia, 06156 Perugia, Italy. Address for correspondence: Dr. Giuseppe Guarro, Department of Plastic and Reconstructive Surgery, University of Perugia, S. Andrea delle Fratte, 06156 Perugia, Italy. E-mail: [email protected] ABSTRACT Aim: Effects of rhinoplasty were already studied from many points of view: otherwise poor is scientific production focused on changes of voice after rhinoplasty. This preliminary study analyzed objectively and subjectively these potential effects on 19 patients who underwent exclusively closed rhinoplasty. Methods: This preliminary evaluation was conducted from September 2012 to May 2013 and 19 patients have undergone primary rhinoplasty with exclusively closed approach (7 males, 12 females). All patients were evaluated before and 6 months after surgery. Each of them answered to a questionnaire (Voice Handicap Index Score) and the voice was recorded for spectrographic analysis: this system allowed to perform the measurement of the intensity and frequency of vowels (“A” and “E”) and nasal consonants (“N” and “M”) before and after surgery. Data were analysed with the Mann-Whitney test. Results: Sixteen patients showed statistically significant differences after surgery. It was detected in 69% of cases an increased frequency of emission of the consonant sounds (P = 0.046), while in 74% of cases the same phenomenon was noticed for vowel sounds (P = 0.048). Conclusion: Many patients who undergo rhinoplasty think that the intervention only leads to anatomical changes and improvement of respiratory function.

Smoking and alcohol can contribute TONSILS AND ADENOIDS to these symptoms. A direct laryngoscopy – an exam of larynx (voice EARS PEDIATRICS box), with biopsy – will help determine if a laryngectomy is indicated. SNORING / SLEEP APNEA Laryngectomy may involve partial or total removal of one or more or both vocal cords. Alteration of voice will occur with either total or partial laryngectomy. Postoperative rehabilitation is usually successful in helping the patient recover a voice that can be understood. The degree of alteration in voice depends on the extent of the disease. Partial or total laryngectomy has been a highly successful method to remove cancer of the larynx. The extent of the tumor invasion, and therefore the extent of surgery, determines the way you will communicate following surgery. The choice of surgery over other forms of treatment such as radiation or chemotherapy is determined by the site of the tumor. It is quite likely that there has been spread of the tumor to the neck; a neck or lymph node dissection may also be recommended. Complete neck dissection (exploration of the neck tissues) is performed in order to remove known or suspected lymph nodes containing cancer that has spread from the primary tumor site.

  • Laryngectomy
    LARYNGECTOMY Definitlon Laryngectomy is the partial or complete surgical removal of the larynx, usually as a treatment for cancer of the larynx. Purpose Normally a laryngectomy is performed to remove tumors or cancerous tissue. In rare cases, it may be done when the larynx is badly damaged by gunshot, automobile injuries, or similar violent accidents. Laryngectomies can be total or partial. Total laryngectomies are done when cancer is advanced. The entire larynx is removed. Often if the cancer has spread, other surrounding structures in the neck, such as lymph nodes, are removed at the same time. Partial laryngectomies are done when cancer is limited to one spot. Only the area with the tumor Is removed. Laryngectomies may also be performed when other cancer treatment options, such as radiation or chemotherapy. fail. Precautions Laryngectomy is done only after cancer of the larynx has been diagnosed by a series of tests that allow the otolaryngologist (a specialist often called an ear, nose, and throat doctor) to look into the throat and take tissue samples (biopsies) to confirm and stage the cancer. People need to be in good general health to undergo a laryngectomy, and will have standard pre-operative blood work and tests to make sure they are able to safely withstand the operation. Description The larynx is located slightly below the point where the throat divides into the esophagus, which takes food to the stomach, and the trachea (windpipe), which takes air to the lungs. Because of its location, the larynx plays a critical role in normal breathing, swallowing, and speaking.

    FAST FACTS AND CONCEPTS #281 CARE OF THE POST-LARYNGECTOMY STOMA Shweta Garg PA-C, Elliott Kozin MD, Daniel Deschler MD Background Many patients with laryngeal cancer require a laryngectomy. While laryngectomies are typically done as a curative cancer surgery, some patients will have recurrences and be seen in palliative care and hospice settings. Laryngectomy stomas differ from tracheostomies (see Fast Fact #250) in important ways, which can profoundly impact a patient’s well being. A working knowledge of the basic management and equipment used in patients with a stoma after laryngectomy can avoid complications and improve a patient’s comfort and safety (1). Laryngectomy Stoma versus Tracheostomy There are a few key differences between a post- laryngectomy stoma and tracheostomy. At the most basic level, a post-laryngectomy stoma is created after a patient undergoes a total laryngectomy, which involves the removal of the larynx, including vocal cords and associated structures. A permanent, direct connection between the trachea and the skin of the neck is made sewing the open end of the trachea to the neck skin forming an opening through which the patient breathes. After a laryngectomy, the patient no longer has a communication between the lungs and oral cavity or nose. These patients are casually referred to as “neck breathers” (2). In contrast, a tracheostomy, also referred to as a tracheotomy, is surgical opening into the trachea to bypass the upper airway, which is not necessarily permanent. A tracheostomy tube is inserted and stents the tracheostomy open, thereby facilitating air exchange. In patients with tracheostomies, the larynx remains present and there is still a connection between the oral cavity and nose to the lungs.

Tracheoesophageal prosthesis (TEP) is the most common voice restoration method following total laryngectomy. Prosthesis extrusion and aspiration occurs in 3.9% to 6.7% and causes dyspnea. Emergency centers are unfamiliar with management of the aspirated TEP. Prior studies report removal of aspirated TEP prostheses under general anesthesia. Laryngectomees commonly have poor pulmonary function, posing increased risks for complications of general anesthesia. We present a straightforward approach to three cases of aspirated TEP prosthesis removed in the ambulatory setting. In each case, aspirated TEP was diagnosed with flexible bronchoscopy under local anesthesia at the time of consultation, and all prostheses were retrieved atraumatically using a biopsy grasper forceps inserted via the side channel of the bronchoscope.
