Emergent management of postpartum hemorrhage for the general and acute care surgeon.

BACKGROUND: Postpartum hemorrhage is one of the rare occasions when a general or acute care surgeon may be emergently called to labor and delivery, a situation in which time is limited and the stakes high. Unfortunately, there is generally a paucity of exposure and information available to surgeons regarding this topic: obstetric training is rarely found in contemporary surgical residency curricula and is omitted nearly completely from general and acute care surgery literature and continuing medical education. METHODS: The purpose of this manuscript is to serve as a topic specific review for surgeons and to present a surgeon oriented management algorithm. Medline and Ovid databases were utilized in a comprehensive literature review regarding the management of postpartum hemorrhage and a management algorithm for surgeons developed based upon a collaborative panel of general, acute care, trauma and obstetrical surgeons' review of the literature and expert opinion. RESULTS: A stepwise approach for surgeons of the medical and surgical interventions utilized to manage and treat postpartum hemorrhage is presented and organized into a basic algorithm. CONCLUSION: The manuscript should promote and facilitate a more educated, systematic and effective surgeon response and participation in the management of postpartum hemorrhage.

Transforming an academic military treatment facility into a trauma center: lessons learned from Operation Iraqi Freedom.

BACKGROUND: To manage the influx of patients with predominately extremity injuries from Operation Iraqi Freedom (OIF), our center was required to transform from a nontrauma academic hospital to a trauma hospital by using a multidisciplinary approach. STUDY DESIGN: A retrospective chart review was performed of casualties from OIF who were received over 14 months. RESULTS: A total of 313 casualties were received. The average number of admissions was 16 per month, except during November 2004, when there were 88 admissions over 7 days. The mean ISS for all patients was 14.1 +/- 10.3. A total of 113 patients (36%) required admission to the intensive care unit for an average of 7.5 +/- 5.2 days. The mean interval between injury and arrival in the continental United States was 6.5 +/- 4.6 days. Most casualties suffered multisystem trauma, with extremity injuries predominating. The multidisciplinary approach to casualty care consisted of several meetings a week and included everyone involved in caring for these combat casualties. CONCLUSIONS: A multidisciplinary approach transformed an existing medical center into a trauma receiving hospital capable of managing and maintaining a surge in patient admissions resulting in minimal morbidity and mortality. This model further supports a multidisciplinary approach to trauma care and could serve as a guideline for transforming existing medical centers into trauma receiving hospitals to deal with patient overflow in the event of future civilian mass casualties.

Warfare-related complex abdominal wall reconstruction using a bioprosthetic regenerate template and negative pressure therapy.

Warfare-related torso/abdominal wounds are often unique and complex and can pose a significant reconstructive challenge. The objective of this manuscript is to report the unique and successful management of a complex warfare-related abdominal wound. A dermal regenerate template in combination with negative pressure wound therapy was used to reconstitute lateral abdominal wall integrity after radical debridement and control of a necrotizing soft tissue infection of the torso. Adjunctive continuous negative pressure (vacuum assisted closure) therapy was used to provide external coverage and encourage the formation of granulation tissue. With this combination therapy, torso wound size decreased in surface area by 82% and the underlying musculofascial defect decreased by 64%. Neovascularization of a 55-cm(2) acellular dermal graft was achieved as evidenced by surface granulation and complete survival of a partial-thickness skin graft. In our patient with a complex war injury, advanced tissue replacement techniques and negative pressure wound therapy resulted in a decreased abdominal wall defect, a restoration of abdominal wall integrity/domain, and allowed for concurrent surgical treatment of complex intra-abdominal injuries.

Effect of Body Mass Index on pregnancy outcomes in nulliparous women delivering singleton babies.

BACKGROUND: The increasing prevalence of obesity in young women is a major public health concern. These trends have a major impact on pregnancy outcomes in these women, which have been documented by several researchers. In a population based cohort study, using routinely collected data, this paper examines the effect of increasing Body Mass Index (BMI) on pregnancy outcomes in nulliparous women delivering singleton babies. METHODS: This was a retrospective cohort study, based on all nulliparous women delivering singleton babies in Aberdeen between 1976 and 2005. Women were categorized into five groups--underweight (BMI < 20 Kg/m2), normal (BMI 20-24.9 Kg/m2) overweight (BMI 25-29.9 Kg/m2), obese (BMI 30-34.9 Kg/m2) and morbidly obese (BMI > 35 Kg/m2). Obstetric and perinatal outcomes were compared by univariate and multivariate analyses. RESULTS: In comparison with women of BMI 20-24.9, morbidly obese women faced the highest risk of pre-eclampsia {OR 7.2 (95% CI 4.7, 11.2)} and underweight women the lowest {OR 0.6 (95% CI 0.5, 0.7)}. Induced labour was highest in the morbidly obese {OR 1.8 (95% CI 1.3, 2.5)} and lowest in underweight women {OR 0.8 (95% CI 0.8, 0.9)}. Emergency Caesarean section rates were highest in the morbidly obese {OR 2.8 (95% CI 2.0, 3.9)}, and comparable in women with normal and low BMI. Obese women were more likely to have postpartum haemorrhage {OR 1.5 (95% CI 1.3, 1.7)} and preterm delivery (< 33 weeks) {OR 2.0 (95% CI 1.3, 2.9)}. Birthweights less than 2,500 g were more common in underweight women {OR 1.7 (95% OR 1.2, 2.0)}. The highest risk of birth weights > 4,000 g was in the morbidly obese {OR 2.1 (95% CI 1.3, 3.2)} and the lowest in underweight women {OR 0.5 (95% CI 0.4, 0.6)}. CONCLUSION: Increasing BMI is associated with increased incidence of pre-eclampsia, gestational hypertension, macrosomia, induction of labour and caesarean delivery; while underweight women had better pregnancy outcomes than women with normal BMI.

Distribution and care of shipboard blast injuries (USS Cole DDG-67).

On October 12, 2000, the destroyer USS Cole was anchored in a foreign port and was severely damaged by explosives in a small craft adjacent to the ship at the port side waterline. Seventeen crew members were killed in the incident. The wounded were evacuated to several medical facilities for their initial care and then to the military hospital in Landstuhl, Germany, and subsequently to the Charette Health Care Center (Naval Medical Center) in Portsmouth, Virginia. There were 35 surviving patients who had sustained 81 total injuries associated with the explosion. The distribution of the injuries included orthopedic, ophthalmologic, soft tissue, otolaryngologic, burns, inhalation, and other miscellaneous injuries. Twenty-seven of the patients were discharged after 24-hour observation. This article reviews the distribution of injuries found in the fatalities and the wounded crew members and the subsequent care required to prepare the military medical community for potential future incidents of this type.

Parietal foramina with cleidocranial dysplasia is caused by mutation in MSX2.

The combination of skull defects in the form of enlarged parietal foramina (PFM) and deficient ossification of the clavicles is known as parietal foramina with cleidocranial dysplasia (PFMCCD). It is considered to be distinct from classical cleidocranial dysplasia (CCD) and is listed as a separate OMIM entry (168550). So far, only two families have been reported and the molecular basis of the disorder is unknown. We present a third family with PFMCCD, comprising four affected individuals in three generations, and demonstrate that a heterozygous tetranucleotide duplication in the MSX2 homeobox gene (505_508dupATTG) segregates with the phenotype. PFMCCD is indeed aetiologically distinct from CCD, which is caused by mutations in the RUNX2 gene, but allelic with isolated PFM, in which MSX2 mutations were previously identified. Our observations highlight the role of MSX2 in clavicular development and the importance of radiological examination of the clavicles in subjects with PFM.
