Fluid resuscitation in pre-hospital management of septic shock

Background

Septic shock is associated with hypovolemia resulting in organs failure and poor prognosis. The first step in hemodynamic resuscitation relies on early fluid expansion. In this study, we describe qualitative and quantitative fluid resuscitation of septic shock initially managed in a pre-hospital setting by a mobile intensive care unit.

The diagnosis of Gestational Diabetes Mellitus and its impact on In Vitro Fertilization pregnancies. A pilot study

BackgroundIn Vitro Fertilization (IVF) is increasingly becoming a necessary mode of reproduction. This high risk group is prone to Gestational Diabetes Mellitus (GDM) which further exposes these pregnancies to an increased risk of adverse outcomes. In light of the limited data in the current literature, further investigation is needed regarding the time of GDM diagnosis in IVF pregnancies as well as the outcome of IVF pregnancies complicated by GDM.MethodsIn this three center pilot cross sectional study, the data of 101 singleton IVF pregnancies complicated by GDM were analyzed. Prompt GDM diagnosis in IVF pregnancies was accomplished by self-blood glucose monitoring (SMBG) from the first antenatal visit and confirmed by an OGTT. To evaluate pregnancy outcome, maternal and fetal complications in the 101 GDM IVF group was compared to 101 IVF as well as 101 spontaneous conceptions (SC). The three groups were matched by age. The effect of demographic and glycemic parameters on the outcome of GDM IVF pregnancies was investigated.ResultsGDM diagnosis was made before the 24th week in 37.6% of the GDM IVF group. The week of delivery was earlier for the GDM IVF group (37 ± 1.7) relative to the IVF (37.9 ± 0.9, p < 0.001) and the SC group (38.1 ± 0.8, p < 0.001). GDM IVF pregnancies exhibited greater preeclampsia rates and 84.8% underwent caesarian section. No significant difference regarding LGA and SGA birth weights was found. Complications of GDM IVF pregnancies were associated with the 1-h postprandial BG (r = 0.267, p = 0.007).ConclusionGDM screening in IVF pregnancies may be considered earlier than the 24th week. IVF pregnancies affected by GDM are prone to increased maternal and fetal complications which are associated with 1-h postprandial BG.     

Thoracoscopic surgery in elderly lung cancer patients

Age is a recognized risk factor for death after thoracotomy in elderly patients with lung cancer. Among other factors, the genesis of this risk is the physiologic debilitation that occurs after division of the intrathoracic respiratory muscles during thoracotomy, as well as the loss of lung tissue after lung resection. Recent advances in video-assisted thoracic surgery (VATS) techniques provide an alternative to standard thoracotomy in elderly lung cancer patients, resulting in decreased recovery times and fewer perioperative complications. Likewise, smaller lung resections (VATS-guided limited wedge resection versus lobectomy with thoracotomy) can be adequate oncologic procedures in patients with a limited life expectancy but resectable disease. We studied these alternative procedures in a cohort of thoracic surgical patients at the Brigham and Women's Hospital in Boston, MA. Proposed investigations of the psychosocial implications of thoracic surgery in the elderly, irrespective of the safety of these maneuvers, are addressed.     

Spontaneous bacterial peritonitis (SBP): clinical,laboratory, and prognostic features. A single-center experience

BACKGROUND: The aim of the present study was to assess the clinical and laboratory characteristics, the course, and the factors influencing the hospital mortality and relapse rate of spontaneous bacterial peritonitis (SBP) in cirrhotic patients admitted in a single University Hospital in Greece. METHODS: The study comprises the evaluation of 81 cirrhotic patients who developed SBP during a 30-month period. RESULTS: The occurrence of SBP was independent of the etiology of liver disease and was symptomatic in 66/81 patients (82%). Encephalopathy, as presenting symptom, occurred mainly in Child C patients. Ascitic fluid culture was positive in 20 patients (25%); E. coli (60%) and Enterococcus faecalis (14%) were the most common bacteria isolated. Empirical treatment was effective in 94% of patients. Renal impairment was observed in 21 patients (26%), six of whom developed hepatorenal syndrome. Total mortality was 10% and was related to the existence of symptoms (P<0.01), ascetic fluid polymorphonuclear cell count (P<0.05), bilirubin levels (P<0.01), and kidney function at the beginning of the episode (P<0.01). The relapse rate was 24.6% and was related to the Child stage (P<0.01). CONCLUSIONS: SBP was asymptomatic in a substantial number of patients. Deterioration of renal function was frequently observed and was the main cause of death. The low (10%) in-hospital mortality seems to be related to earlier diagnosis and treatment. Relapse was associated with the severity of liver disease.
