Sepsis Management in Prolonged Field Care: 28 October 2020.

This Role 1 prolonged field care (PFC) guideline is intended for use in the austere environment when evacuation to higher level of care is not immediately possible. A provider must first be an expert in Tactical Combat Casualty Care (TCCC). The intent of this guideline is to provide a functional, evidence-based and experience-based solution to those individuals who must manage patients suspected of having or diagnosed with sepsis in an austere environment. Emphasis is placed on the basics of diagnosis and treatment using the tools most familiar to a Role 1 provider. Ideal hospital techniques are adapted to meet the limitations of austere environments while still maintaining the highest standards of care possible. Sepsis and septic shock are medical emergencies. Patients suspected of having either of these conditions should be immediately evacuated out of the austere environment to higher echelons of care. These patients are often complex, requiring 24-hour monitoring, critical care skills, and a great deal of resources to treat. Obtaining evacuation is the highest treatment priority for these patients. This Clinical Practice Guideline (CPG) uses the minimum, better, best paradigm familiar to PFC and gives medics of varying capabilities and resources options for treatment.

Levothyroxine in euthyroid autoimmune thyroiditis and type 1 diabetes: a randomized, controlled trial.

CONTEXT: Patients with type 1 diabetes (T1D) have an increased risk of autoimmune thyroiditis (AIT). OBJECTIVE: Our objective was to determine whether levothyroxine (l-T(4)) treatment prevents the clinical manifestation of AIT in euthyroid subjects with T1D. DESIGN AND SETTING: We conducted a prospective, randomized, open, controlled clinical trial at six tertiary care centers for pediatric endocrinology and diabetes. PATIENTS: Of 611 children and adolescents with T1D, 89 individuals (14.5%) were identified with positive thyroid peroxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb), or both. Of these, 30 patients (age, 13.3 +/- 2.1 yr) met the inclusion criteria and were randomized to receive l-T(4) (n = 16 patients) or no treatment (n = 14 patients). INTERVENTION: l-T(4) (1.3 microg/kg daily) was given for 24 months in the treatment group, followed by an additional observation period of 6 months in both groups. MAIN OUTCOME MEASURES: Thyroid gland volume (as determined by ultrasound), serum levels of TSH, thyroid hormones, TPOAb, and TgAb were assessed every 6 months for 30 months. RESULTS: Mean thyroid volume decreased in the treatment group after 24 months (-0.60 sd score) and increased in the observation group (+ 1.11 sd score; P = 0.0218). Serum thyrotropin, free T(4), TPOAb, and TgAb levels were not significantly different in both groups during the entire study period. Hypothyroidism developed in three individuals treated with l-T(4) and in four untreated patients (conversion rate, 9.3% per year). CONCLUSIONS: In this study in euthyroid patients with AIT and T1D, l-T(4) treatment reduced thyroid volume but had no effect on thyroid function and serum autoantibody levels.

Minimally invasive port access versus conventional mitral valve surgery: prospective randomized study.

BACKGROUND: We compared the port access mitral valve surgery with the conventional procedure through median sternotomy in a prospective randomized study. METHODS: Forty elective patients with mitral valve disease were prospectively randomized to undergo minimally invasive (group I) or conventional (group II) mitral valve operation. The patients of group I had limited access through right small anterior thoracotomy and a femorofemoral cardiopulmonary bypass system using the endoclamp technique. To assess the efficiency and safety of the procedure, intraoperative and postoperative clinical data and markers of myocardial, cerebral, and lower limb ischemia were collected. Pulmonary function tests were performed to compare the preservation of pulmonary function. Neuropsychological tests were conducted for quantification of neurological and cognitive disorders. RESULTS: Mitral valve reconstructions were performed in 28 patients (70%) in both groups. Intraoperative procedure-associated problems were experienced in 9 patients (45%) in group I, and 6 of them (30%) had to be converted to direct transthoracic aortic clamping. Markers of myocardial and cerebral damage as well as pulmonary and neuropsychological tests did not show statistically significant difference between groups. CONCLUSIONS: The minimally invasive port access technique for mitral valve surgery can be done with similar clinical safety as procedures through median sternotomy. The problems with endoclamping have forced us to change our practice to the more simple and economic transthoracic aortic clamping technique.
