Complications of Crotalidae antivenin therapy.

Polyvalent antivenin is the mainstay of treatment of serious snake envenomation. Its use, however, has been challenged as being unnecessary in minor envenomations and potentially hazardous due to allergic complications. Our institution routinely uses antivenin, and this report focuses on the allergic complications of this therapy. Forty patients with Crotalidae snake bites were evaluated and treated over a 7-year period. Twenty-six patients received a total of 507 vials of antivenin, the dose correlating with the clinical severity of envenomation. All patients were skin tested. Immediate hypersensitivity reactions occurred in six patients (23%). Cutaneous manifestations alone occurred in three of these patients, while systemic anaphylaxis occurred in three. Twenty patients were available for followup, and ten (50%) developed serum sickness. Skin testing was not reliable in predicting the development of immediate (anaphylaxis) or delayed (serum sickness) hypersensitivity reactions. Treatment of antivenin allergic reactions was uniformly effective, with no mortality, minimal morbidity, and no chronic sequelae.

Systemic antibiotic treatment in burned patients.

Systemic antibiotics are a valuable therapeutic modality in the burned patient when properly used. Injudicious use, however, may not only fail to be beneficial to the patient but also may produce harmful effects--either through direct toxicity or by contributing to the emergence of resistant strains of micro-organisms. General guidelines and principles for systemic antibiotic use include the following: The burned patient, despite all efforts, will be exposed to microorganisms. No single agent or combination of agents can destroy all the organisms to which the burned patient is exposed. Treatment involves first identifying the organism responsible for clinical sepsis, then choosing appropriate agents. Combinations of antibiotics are not always synergistic or even additive in effect. Multiagent therapy may have the untoward effect of predisposing to superinfection by yeast, fungi, or resistant organisms. Antibiotics should be used for a long enough period to produce an effect, but not long enough to allow for emergence of opportunistic or resistant organisms. Dosages must be adjusted based on serum concentrations when serum assays are available. In general prophylactic systemic antibiotics are indicated in only a few clinical situations including the immediate preoperative and postoperative periods associated with excision and autografting, and possibly in the early phases of burns in children. The penetration of systemic antibiotics into burn eschar remains an area not fully studied; hence, they cannot be the only therapeutic modality used to treat burn wound infection. Systemic dosages of antibiotics in burns will require alteration depending on the clinical status of the patient. The choice of agent requires a thorough knowledge of side effects, toxicity, and potential benefit. Above all, active surveillance and monitoring of the burned patient and the environment in which he or she is being treated is mandatory for effective treatment. The increasing number of new antimicrobial agents has presented a new dilemma to the practicing clinician because many of these agents have not been evaluated thoroughly in the burned population. With further studies, the armamentarium of the burn treatment team will inevitably increase. It is in this manner only that so many of the unanswered questions will be solved, and that infection will start to decline as the major cause of death in the burned population.

Paramedic perception of elapsed field time.

An independent observer was placed with city paramedic teams to: a) record exactly how long emergency field procedures take; and b) determine the paramedic's perception of elapsed field time. One hundred eighteen runs were monitored; 33% required advanced life support skills, and 36% were for trauma. The response time (mean +/- S.E.M.) averaged 5.4 +/- 0.26 min, scene time 11.2 +/- 0.54 min, and transport time 9.5 +/- 0.86 min. The average time required to perform scene procedures ranged from 1.5 +/- 0.5 min for defibrillation to 5.0 +/- 0.47 min to start an IV. Paramedic perception of elapsed time for the entire run varied from the actual time by an average absolute value of 20%, with the greatest errors occurring in scene time estimates. Paramedics tended to overestimate elapsed time during short runs, and underestimate time on long runs. This report provides realistic field procedure times for urban paramedics. Distortion of time perception in the field environment emphasizes the need for strict medical control.

Pediatric maxillofacial trauma: unique features in diagnosis and treatment.

The purpose of this study was to review mechanisms, etiologies, associated injuries, and treatment of maxillofacial trauma in children and to compare them to similar adult injuries. Thirty blunt injuries (1984-1986) comprised the children's group, and 176 injuries, the adult group. Multiple associated injuries were more common in children, the most frequent being CNS and orthopedic injuries. Detailed anatomy of mandibular fractures required pleuridirectional tomography in 63% of the pediatric cases compared to 12% in adults. In the children's group, the mandibular fractures were favorable in 56% of cases compared to 15% in adults. Children required shorter periods of intermaxillary fixation with no child requiring reapplication of fixation. Based on these comparisons, a protocol for the management of pediatric maxillofacial injuries has been developed.

Hypothermia in trauma victims: an ominous predictor of survival.

Hypothermia in trauma patients is generally considered an ominous sign, although the actual temperature at which hypothermia affects survival is ill defined. In this study, the impact of body core hypothermia on outcome in 71 adult trauma patients with Injury Severity Scores (ISS) greater than or equal to 25 was analyzed. Forty-two per cent of the patients had a core temperature (Tc) below 34 degrees C, 23% below 33 degrees C, and 13% below 32 degrees C. The mortality of hypothermia patients was consistently greater than those who remained warm, regardless of index core temperature. Mortality if Tc less than 34 degrees C = 40%, less than 33 degrees C = 69%, less than 32 degrees C = 100%, whereas mortality if Tc greater than or equal to 34 degrees C = 7%, and greater than or equal to 32 degrees C = 10%. Mortality and the incidence of hypothermia increased with higher ISS, massive fluid resuscitation, and the presence of shock. Within each subgroup (i.e., greater ISS, massive fluid administration, shock) the mortality of hypothermic patients was significantly higher than those who remained warm. No patient whose core temperature fell below 32 degrees C survived.

Infections in burn patients.

Systemic sepsis resulting from invasive infection remains the leading cause of death among patients hospitalized with major thermal injury. Prevention of infection and death in burn patients requires a thorough knowledge of the multiple predisposing factors involved and expert application of appropriate diagnostic, supportive, and therapeutic modalities. The improved survival in this population is a result of all these factors, not any one. It is this principle and the adherence to a treatment program that encompasses all the modalities which are so essential in the care of burn patients if continuing progress is to be made in this field. This article describes the current management of infection and infection control in burn patients. The burn wound and pulmonary system remain the major foci for infection in this population. Less common types of infection include suppurative thrombophlebitis, suppurative chondritis, bacterial endocarditis, urinary tract sepsis, sinusitis, intra-abdominal sepsis, and infections of the eyes. Prophylaxis protocols involve proper control of the environment and an anticipation of bacterial colonization. A number of specific monitoring and treatment guidelines have evolved that have proved effective over the years in minimizing morbidity and mortality.

Splenic abscess caused by Blastomyces dermatitidis.

We have reported a case of fungal splenic abscess caused by Blastomyces dermatitidis. Splenic abscess is an uncommon disorder, and fungus as the causative organism is rare. The diagnosis of splenic abscess can be rapidly made with radionuclide and CT scanning and ultrasonography. Splenectomy with appropriate antifungal chemotherapy is the currently recommended therapy.

Laryngotracheal trauma: a protocol approach to a rare injury.

Laryngotracheal trauma is rare and complications are frequent. Twelve major series totalling 392 cases have been published over the past decade, with complication rates as high as 40%. We have treated over 30,000 trauma victims at our Level I Trauma Center over the past 5 years, of which 109 had neck injuries, but only 12 suffered cervical laryngotracheal trauma. The mechanism of injury was penetrating in eight and blunt trauma in four. The time to tracheostomy decannulation varied from 7 to 60 days. Airway patency was assured without stenosis or significant granulation tissue in 10 of the 12 patients. Three patients suffered permanent voice changes. Based on review of the 392 previously reported cases and a critical analysis of our 12 cases, a detailed management algorithm is proposed.

Maximum survival in pediatric trauma: the ideal system.

One hundred consecutive pediatric trauma deaths (0.01-18 yrs) were analyzed for their survival potential in an optimally functioning EMS/Trauma system in Mobile, Alabama (1980-1982). Thorough evaluation of all phases of care by paramedic run sheets, ER records, hospital records, and autopsy reports, revealed that 47/100 victims could have never survived due to the extreme nature of their injuries, and 53/100 victims had the potential of surviving if the EMS/Trauma system functioned optimally. Errors in care were identified in those cases deemed potentially salvageable. Identification phase errors were found in 79% of potentially salvageable victims. Field treatment errors occurred in 36%, transport errors in 23%, and definitive care errors in 17% of those considered to be potentially salvageable. By evaluating where in an EMS/Trauma system errors occur and then by correcting those errors, it should be possible to minimize the mortality rate in pediatric trauma.

BB and pellet guns--toys or deadly weapons?

BB and pellet weapons are not included in gun control laws and are often sold as children's toys. Injuries caused by these weapons have been considered trivial unless they involve vulnerable surface organs such as the eye. The purpose of this study was to review the management of six cases of pellet or BB gun injuries that required abdominal exploration at the University of South Alabama Medical Center from January 1980 through June 1982. Five of the six patients had significant internal injuries including perforations of the stomach, jejunum, liver, and pancreas. The ballistics of pneumatic weapons are reviewed. The muzzle velocities of many of these weapons necessitate that wounds caused by these weapons be handled with the same principles as for any small-caliber, low-velocity (less than 1,200 feet/second) weapons. Public education programs are urgently needed to educate parents as to the potential danger involved in purchasing these weapons for unsupervised use as toys by children.

Transplantation of the cryopreserved nipple-areolar complex.

The full nipple-areolar complex of dogs has been successfully removed, cryopreserved using a controlled-rate freeze protocol, and reimplanted without loss of viability. The technique for reimplantation calls for the use of a new fixed double bolus technique that prevented dislodging or contamination in all but 2 cases. The feasibility of performing this procedure in humans is discussed.

Screening the nipple for involvement in breast cancer.

On the basis of independent clinical and pathological screens, mastectomy patients can be effectively classified into high-risk and low-risk groups for neoplastic involvement of the nipple-areolar complex. Clinical criteria included gross nipple signs, cutaneous signs, and tumor location, size, and bilaterality. Pathological criteria comprised subareolar involvement multicentricity, and nodal involvement. Fifty consecutive women undergoing mastectomy for cancer at the New York Hospital-Cornell University Medical Center underwent classification into high-risk and low-risk groups on the basis of these criteria. Fifty-four percent of the patients studied passed the screens and were included in the low-risk group. The incidence of nipple involvement in this group was 0. In the remaining 46%, failing either or both of the screens and constituting the high-risk group, the incidence of neoplastic involvement of the nipple was 35%. All involved nipples fell into this group.

Burn injury. Analysis of survival and hospitalization time for 937 patients.

The charts of 937 patients have been reviewed for survival and length of stay. Probit analysis and binary logistic regression has been performed to develop probability of dying contours incorporating age and per cent burn. It appears that improvement in survival has occurred over the last 16 years. The length of hospital stay has also been evaluated. A significant decrease in hospitalization time has occurred in the past year with the advent of a selective wound excisional protocol, without adversely affecting survival. A burn bed requirement chart is presented which incorporates age, burn size, survival probability and predicted length of stay. The chart allows for estimation of burn bed needs for a known or predicted population of regional burn victims.
