Methemoglobinemia Following Transesophageal Echocardiography: A Case Report and Review

ECHOCARDIOGRAPHY, Issue 4 2006
Swarnalatha BheemReddy M.D.
Benzocaine (ethyl aminobenzoate) is a topical anesthetic widely used for oropharyngeal anesthesia prior to transesophageal echocardiography (TEE). Topical anesthetics have been reported to cause methemoglobinemia, but this adverse event is extremely rare and has not been listed as one of the possible complications of TEE. However, recently the number of published case reports of TEE-associated methemoglobinemia has increased. Since its first description in 1950, 65 cases of methemoglobinemia have been reported including a recent report of five cases from a single center. Physicians who are not familiar with the association of TEE with benzocaine-induced methemoglobinemia may not recognize the idiosyncratic and often nonspecific characteristic of this condition. Recognition is critical, however, since left untreated methemoglobinemia can lead to cardiopulmonary compromise, neurological sequelae, and even death. The current report documents an additional case of TEE-associated methemoglobinemia from a high-volume (8000 cases /year including 400,450 TEE/year) echo lab. A review of the literature suggests that this complication may be more prevalent, than generally appreciated. This case report emphasizes the importance of appropriate dose, recognition, and the treatment of this entity to cardiologists performing TEE. [source]


Barriers that delay children and young people who are dependent on mechanical ventilators from being discharged from hospital

JOURNAL OF CLINICAL NURSING, Issue 1 2002
Cert.Ed.MILT, JANE NOYES MSc
,,A qualitative study of user perspectives published previously by the author found that children and young people who are dependent on ventilators spend many months and in some cases years in hospital when they no longer had a medical need or wanted to be there. ,,This second paper is drawn from the same qualitative study and reports on the barriers that the children and young people who are dependent on ventilators, and their parents, described as important factors in preventing their discharge from hospital. ,,Six issues were identified as significant barriers that prevented the children and young people from being discharged. These were: the attitudes of professionals; the lack of joint commissioning and accounting responsibility; general poor management both within the health service and in collaborating with other services; complex social issues; housing problems; and a general lack of auditing and outcome measures. ,,The generalizability of the findings is unknown. However, recommendations are made in relation to the need to establish joint commissioning and accounting responsibility for care and services, and to establish outcome measures to monitor the effectiveness and appropriateness of the care and services provided.

Electrosurgery, Pacemakers and ICDs: A Survey of Precautions and Complications Experienced by Cutaneous Surgeons

DERMATOLOGIC SURGERY, Issue 4 2001
Hazem M. El-Gamal MD
Background. Minimal information is available in the literature regarding the precautions implemented or complications experienced by cutaneous surgeons when electrosurgery is used in patients with pacemakers or implantable cardioverter-defibrillators (ICDs). The literature pertinent to dermatologists is primarily based on experiences of other surgical specialties and a generally recommended thorough perioperative evaluation. Objective. To determine what precautions are currently taken by cutaneous surgeons in patients with pacemakers or ICDs, and what types of complications have occurred due to electrosurgery in a dermatologic setting. Methods. In the winter of 2000, a survey was mailed to 419 U.S.-based members of the American College of Mohs Micrographic Surgery and Cutaneous Oncology (ACMMSCO). Results. A total of 166 (40%) surveys were returned. Routine precautions included utilizing short bursts of less than 5 seconds (71%), use of minimal power (61%), and avoiding use around the pacemaker or ICD (57%). The types of interference reported were skipped beats (eight patients), reprogramming of a pacemaker (six patients), firing of an ICD (four patients), asystole (three patients), bradycardia (two patients), depleted battery life of a pacemaker (one patient), and an unspecified tachyarrhythmia (one patient). Overall there was a low rate of complications (0.8 cases/100 years of surgical practice), with no reported significant morbidity or mortality. Bipolar forceps were utilized by 19% of respondents and were not associated with any incidences of interference. Conclusions. Significant interference to pacemakers or ICDs rarely results from office-based electrosurgery. No clear community practice standards regarding precautions was evident from this survey. The use of bipolar forceps or true electrocautery are the better options when electrosurgey is required. These two modalities may necessitate fewer perioperative precautions than generally recommended, without compromising patient safety. [source]


Ticks and Lyme borreliosis in an alpine area in northeast Italy

MEDICAL AND VETERINARY ENTOMOLOGY, Issue 3 2010
F. NAZZI
A 2-year study was conducted in a mountainous area of northeast Italy to evaluate the occurrence and distribution of ticks, as well as to assess the prevalence of the spirochaete Borrelia burgdorferi sensu lato. All ticks collected were Ixodes ricinus L. (Parasitiformes: Ixodidae). In general, most nymphs and adult ticks were collected from April to July. Tick density was highly variable among sites; however, two areas with different infestation levels were recognized. Prevalences of B. burgdorferi s.l. in nymphal stages were rather variable between sites; overall the prevalence of infected nymphs in the whole area was slightly higher than 20%. The prevalence of B. burgdorferi s.l. in nymphs does not seem to be correlated with nymph density. The correlation between the incidence of Lyme borreliosis (reported human cases/1000 inhabitants/year) and Borrelia prevalence in nymphs was not significant, although a significant correlation was found between borreliosis incidence and nymph density.
