Temporary intravenous bag silo closure in severe abdominal trauma.

Several temporary abdominal wall closure techniques have been described in the literature. We present our experience with an inexpensive and efficient method of temporary abdominal closure when bowel edema and distension preclude safe primary closure. Our technique is a variation of the silon (silo) closure used in the repair of gastroschisis and omphalocele, using a pre-gas-sterilized, soft 3-L plastic cystoscopy fluid irrigation bag cut to an oval shape and stapled or sutured to the skin edges of the wound.

Incidence of Tracheal Stenosis and Other Late Complications After Percutaneous Tracheostomy

ObjectiveTo determine the incidence of tracheal stenosis, voice and breathing changes, and stomal complications after percutaneous dilatational tracheostomy (PDT). MethodsFrom December 1992 through June 1999, 420 critically ill patients underwent 422 PDTs. There were 340 (81%) long-term survivors, 100 (29%) of whom were interviewed and offered further evaluation by fiberoptic laryngotracheoscopy (FOL) and tracheal computed tomography (CT). Tracheal stenosis was defined as more than 10% tracheal narrowing on transaxial sections or coronal and sagittal reconstruction views. Forty-eight patients agreed to CT evaluation; 38 patients also underwent FOL. CT and FOL evaluations occurred at 30 ± 25 (mean ± standard deviation) months after PDT. ResultsTwenty-seven (27%) patients reported voice changes and 2 (2%) reported persistent severe hoarseness. Vocal cord abnormalities occurred in 4/38 (11%) patients, laryngeal granuloma in 1 (3%) patient, focal tracheal mucosal erythema in 2 (5%) patients, and severe tracheomalacia/stenosis in 1 (2.6%) patient. CT identified mild (11–25%) stenosis in 10 (21%) asymptomatic patients, moderate (26–50%) stenosis in 4 (8.3%) patients, 2 who were symptomatic, and severe (>50%) stenosis in 1 (2%) symptomatic patient. Ten patients (10%) reported persistent respiratory problems after tracheal decannulation, but only four agreed to be studied. Two patients had moderate stenosis, and one had severe stenosis. One patient’s CT scan was normal. No long-term stomal complications were identified or reported. ConclusionsSubjective voice changes and tracheal abnormalities are common after endotracheal intubation followed by PDT. Long-term follow-up of critically ill patients identified a 31% rate of more than 10% tracheal stenosis after PDT. Symptomatic stenosis manifested by subjective respiratory symptoms after decannulation was found in 3 of 48 (6%) patients.

Thoracic Bb Injuries in Pediatric Patients

Penetrating thoracic injury from BB shot remains an innocuous event in most patients, but factors including location, proximity, gun type, and patient weight may identify groups at risk. The following cases demonstrate morbidity and mortality in two patients, and this experience may suggest the need for reassessment of this injury.

Transesophageal echocardiography for diagnosing aortic injury : a case report and summary of current imaging techniques

Early diagnosis and rapid treatment of lethal aortic injuries associated with blunt trauma remain a challenge for trauma surgeons. The following case demonstrates the use of transesophageal echocardiography for definitive diagnosis of an aortic injury from blunt trauma. A summary of current diagnostic modalities is also presented.

Air rifles—Lethal weapons

Modern air rifles are very powerful and potentially dangerous, yet they are sold without a license because they are considered toys. We report on 16 patients who were shot with air rifles. Nine of these patients were treated in the last 3 years. Seven patients sustained injuries to the chest and upper back. The BB (ball bearing) penetrated the aorta of two patients, one of whom died. One of two patients shot in the abdomen had injuries to the iliac artery and the colon. Three patients were shot in the head and neck, three in the extremities, and one through the penis. Particularly alarming to us is the fact that nine patients had been shot intentionally after minor arguments with other children. The assailants were neighborhood children in seven cases, a friend in five, and a sibling in two.

Ground-level falls: 9-year cumulative experience in a regionalized trauma system

Ground-level falls (GLFs) are the leading cause of nonfatal hospitalized injuries in the US. We hypothesized that risk-adjusted mortality would not vary between levels of trauma center verification if regional triage functioned appropriately. Data were collected from our regional trauma registry for the years 2001 through 2009. A multilevel mixed-effects logistic regression model was developed to compare risk-adjusted mortality rates by trauma center level and by year. GLF patients numbered 8202 over 9 years with 2.1% mortality. Mean age was 74.5 years and mean probability of death was 0.021 (95% confidence interval [CI], 0.020–0.021). The level I center-treated patients had the highest probability of death (0.033) compared to levels II and III/IV patients (0.023 and 0.018, respectively; P < 0.001), with the highest mortality (6.0%, 3.1%, and 1.1% for levels I, II, and III/IV; P < 0.001). The adjusted odds ratio of mortality was lowest at the level I center (0.71; 95% CI, 0.56–0.91), while no difference existed between level II (1.17; 95% CI, 0.90–1.51) and level III/IV centers (1.22; 95% CI, 0.90–1.66). The 95% CIs for risk-adjusted mortality by year overlapped the 1.0 reference line for each year from 2002 to 2009. In conclusion, regional risk-adjusted mortality for GLF has varied little since 2002. More study is warranted to understand the lower risk-adjusted GLF mortality at the level I center for this growing patient population.
