Burns caused by medical therapy.

A burn injury may occur as an unexpected consequence of medical treatment. We examined the burn prevention implications of injuries received in a medical treatment facility or as a direct result of medical care. The records of 4510 consecutive admissions to 1 burn center between January 1978 and July 1997 were retrospectively reviewed. A cohort of 54 patients burned as a result of medical therapy was identified and stratified by location (home vs medical facility) and by mechanism of injury. Twenty-two patients were burned in a medical treatment facility, including 12 patients who were burned as a result of careless or unsupervised use of tobacco products. Thirty-two patients were burned as a result of home medical therapy, including 9 patients who had scald injuries from vaporizers, 8 patients who were burned by simultaneous use of cigarettes and home nasal oxygen therapy, and 11 patients who were burned by therapeutic application of heat. In contrast to previous studies, no patient was burned by the use of medical laser devices. To further decrease burn risk from medical therapy we advocate the prohibition of cigarette smoking in any medical facility. Continued tobacco use may represent a contraindication to home oxygen therapy. Given the lack of proof of efficacy combined with the potential for burn injury, the use of vaporizers to treat upper respiratory symptoms should be discouraged. Patients with diminished sensation or altered mental status are at increased risk of burn injury from bathing or topical heat application and merit closer monitoring during these activities.

Interactions of thyroid hormones and catecholamines in severely burned patients.

A prospective study of thyroid function was performed in 20 thermally injured patients. Serum levels of free thyroxine (FT4) and free 3,5,3'-triiodothyronine (FT3) were measured in 10 patients (mean age, 34 years; mean burn size, 56%) studied during a period of clinical deterioration and in 10 patients of comparable age and burn size who were clinically stable. Both FT4 and FT3 values were significantly lower in the unstable patients, P less than .01. All FT3 values for the unstable patients, 193 +/- 14 pg/dl (mean +/- SE), were beneath the normal range for FT3, 230-669 pg/dl. Interactions of thyroid hormone and catecholamines were assessed in eight additional burned patients (mean age, 31 years, mean burn size, 57%). Plasma norepinephrine correlated negatively with serum T3 (r = -.70; P less than .01). A similar reciprocal relationship was described for plasma epinephrine and serum T3 (r = -.56; P less than .025). The reciprocal relationship described for serum T3 and plasma norepinephrine and epinephrine is consistent with that of similar observations in states of clinical hypothyroidism. In conclusion, the observations of suppression of free thyroid hormone with clinical deterioration and of a reciprocal relationship between T3 and catecholamines suggest that the critically ill burned patient may be chemically hypothyroid; this may be an adaptive response to assumption of metabolic control by the sympathetic nervous system and does not result from caloric deprivation.(ABSTRACT TRUNCATED AT 250 WORDS)

Mafenide-induced pseudochondritis.

Wound infections following burns of the ear can result in the devastating complication of chondritis, requiring resection of cartilage. To prevent this, it has become common practice to dress the burned ear with mafenide acetate. We have observed six hypersensitivity reactions to the mafenide that occurred following several weeks of continuous use of the drug. The reaction mimics chondritis, causing edematous, erythematous, pruritic ears with a profuse serous exudate. There is no associated fever, systemic signs, or pain on motion of the cartilage. Treatment consists of stopping the mafenide. Recovery occurs within 72 hours. Differentiating between chondritis, with its required surgical and antibiotic treatment, and a hypersensitivity reaction is necessary to avoid further iatrogenic injury.

The burned hemophiliac.

Reports of the care of burned hemophiliac patients requiring cutaneous autografting are rare. A 28-year-old white male with classic hemophilia A sustained a 30.5% total body surface area burn. The patient received standard topical antimicrobial therapy and the majority of his burn wound healed. While undergoing therapy, multiple tooth extractions were recommended. On postburn day 25 the patient underwent multiple tooth extractions plus excision and grafting of his unhealed burn after preoperative infusion of cryoprecipitate. Despite a maximum factor VIII concentration of only 23%, no remarkable bleeding occurred from the excision sites, the skin graft donor site, or the tooth extraction wounds. Preoperative infusion of cryoprecipitate does not appear to be required for split-thickness skin graft harvest or excision of burns within the dermis.

Use of vascular clips to approximate skin grafts.

During excisions of acute burn wounds, attention to aesthetic detail often is secondary to the goal of rapid gross coverage. Expeditious approximation of adjacent skin grafts has long presented a problem to surgeons. Some surgeons simply place the grafts next to each other, relying on the intervening areas to "scar in". Others use staples to hold grafts together. These staples, however, can become buried under healed grafts and can cause "foreign body" reactions in the months and years ahead. In addition, staples cause bleeding beneath the newly placed grafts, contributing to hematoma formation. Still other surgeons suture or tape adjacent pieces of skin graft together, a tedious exercise. The cosmetic result of these techniques is often less than optimal resulting in the unfortunately familiar "patchwork quilt" appearance of grafts interweaved among scars. Vascular clips have proven to be useful for holding adjacent pieces of skin graft together.

The epidemiology and prevention of burn injuries to firefighters.

From 1981 to 1991, 746 firefighters were treated for burn injuries at New York Hospital-Cornell Burn Center. The predominant anatomic areas of deep injury were the hands and lower extremities. An educational program was initiated that urges proper use of the protective gear as designed. A reduction in the number of burns to the hands subsequently was noted, but lower extremity burns persisted. Analysis of the lower extremity burns revealed that firefighters functioning as nozzle operators were particularly prone to injury because of inadequate lower extremity protection. Improved protection of the lower extremities with the introduction of bunker pants could reduce the incidence of the injuries and result in substantial cost savings for the City of New York.

Elder abuse: a call to action.

An estimated 2 million people a year are victims of elder abuse, which ranges from neglect and mistreatment to physical abuse. By the year 2020, a full 22% of the population will be aged 65 or older. This demographic explosion demands that we identify and protect those at risk. To investigate the incidence of elder abuse or neglect (EAN) and to determine clinician awareness of associated risk factors, we conducted a 1-year retrospective review of thermally injured patients aged 60 or older. Data included age, total body surface area burned, mechanism of injury, length of hospital stay, mortality, abuse or neglect risk factors, and referral to the appropriate social agency. We found that our elderly patients (n = 28) were poorly screened for EAN. While 64% to 96% of patients were screened for cognitive impairment, overall health, and financial resources, none were screened for risk factors of emotional isolation. None of the patient's caregivers, including any spouses, roommates, or guardians, were screened for risk factors of substance abuse, familial violence, dependency needs, or external stresses. With the use of available data, we were able to place 11 patients on the following levels of abuse or neglect: 1) low risk for abuse; 2) self-neglect; 3) neglect; and 4) abuse. By this scale, 7 patients (64%) were victims of self-neglect, 3 patients (27%) were victims of neglect, and 1 patient (9%) was a victim of abuse. Adult Protective Services intervened in 2 cases. Recognizing that all cases of EAN should be preventable, we cannot accept the socioeconomic impact of this entity. The 11 patients identified as victims of neglect, self-neglect, or abuse accounted for 135 hospital days and 8 fatalities. Before we can address EAN, health care personnel must be made aware of the problem and routine screening for risk factors must be implemented. The true incidence of EAN is likely underestimated because health care providers have difficulty recognizing its features. A standard assessment tool to screen for neglect or abuse should be used for each older adult admission.

Acute respiratory failure that complicates the resuscitation of pediatric patients with scald injuries.

Respiratory failure that requires endotracheal intubation is an uncommon but potentially fatal complication of scald burns in children. Because scalds are rarely associated with a direct pulmonary injury, the pathophysiology of respiratory failure is unclear. A possible mechanism may be upper airway edema, diminished pulmonary compliance secondary to fluid resuscitation, or both. To identify an at-risk population for intubation after a scald injury, the hospital courses of 174 consecutive patients under the age of 14 years who were admitted after a scald injury to a single burn center during a 6-year period were examined. Seven of these patients (4%) required endotracheal intubation. No patient older than 2.8 years or who had a scald injury that covered less than 19% of the total body surface area required intubation. Patients who required intubation were younger (mean age, 1.4 vs. 2.8 years, P<.001), had a larger mean burn size (29.9% vs. 12.3% total body surface area, P<.001), and required more fluid resuscitation (7.66 vs. 4.07 cc/kg per percentage of total body surface area burned, P<.001) than patients who did not require intubation. Examination of the adequacy of resuscitation revealed that the intubated patients had an average hourly urine output of 0.84 cc/kg during the first 24 hours, suggesting that resuscitation was not excessive. Multivariate analysis demonstrated that both larger burn size (P = .041) and younger age (P = .049) were independent predictors of the need for intubation. Young patients with large body surface area burns that required large volumes of resuscitation comprise an at-risk group for respiratory failure after a scald injury. Increased vigilance is merited during the resuscitation of these patients.

The relationship of burnout, stress, and hardiness in nurses in a military medical center: a replicated descriptive study.

The purpose of this descriptive study was to determine whether the personality trait of hardiness is a predictor of burnout and whether it can buffer the effect of stress on burnout. Forty-nine registered nurses working in 7 special care units completed the Tedium Burnout Scale, the Nursing Stress Scale, and the Hardiness Test. Results indicate that burnout, stress, and hardiness had a significant relationship (P < .001). Hierarchical multiple regression analysis indicated that hardiness alone accounted for 35% of burnout variance (P < .05) and that the addition of stress had no effect. A previous study reported that burn unit nurses had the least burnout and greatest hardiness. However, in this study, nurses from the Burn Intensive Care Unit had the highest burnout and stress scores and the lowest hardiness scores of nurses from the 7 units. This study confirms findings by a previous study that hardiness is a predictor of burnout but is not a buffer in the stress-burnout relationship. To further understand burnout and hardiness, longitudinal and multisite studies that include burn units are recommended.

A nasal trumpet orthosis to maintain nares openings and respiratory function for patients with facial burns: a case report.

Management of facial burns is a challenge to the burn team because it may lead to functional and cosmetic compromise. Severe scarring of the nares may lead to nasal occlusion. This article introduces a method of maintaining nasal patency that allows respiratory exchange through the use of a custom-fabricated, semirigid tubular orthosis. The technique for fabrication is reviewed, and the use of the device is addressed through a case report. This inexpensive, readily available device is useful in preventing nasal occlusion that results from scar formation.
