Rapid weight loss is associated with preoperative hypovolemia in morbidly obese patients.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND In morbidly obese patients (MO), adequate levels of venous return (VR) and left ventricular filling pressures (LVFP) are crucial in order to augment perioperative safety. Rapid weight loss (RWL) preparation with very low calorie diet is commonly used aiming to facilitate bariatric

Obese trauma patients are at increased risk of early hypovolemic shock: a retrospective cohort analysis of 1,084 severely injured patients.

BACKGROUND Morbid obesity and its consequences are considered risk factors for adverse outcome in trauma, although the pathophysiologic mechanisms are incompletely understood. The aim of this study was to compare initial resuscitation, treatment, and short-term outcome of severely injured patients

Perioperative fluid guidance with transthoracic echocardiography and pulse-contour device in morbidly obese patients.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND In bariatric surgery, non- or mini-invasive modalities for cardiovascular monitoring are addressed to meet individual variability in hydration needs. The aim of the study was to compare conventional monitoring to an individualized goal-directed therapy (IGDT) regarding the need of

Glucose tolerance in the obese surgical patient.

Numai utilizatorii înregistrați pot traduce articole

Intraoperative glucose metabolism was studied in seven grossly obese patients during an intestinal bypass surgical procedure. Preoperative fasting plasma glucose levels were in the low normal range. Results of intravenous glucose tolerance studies during the preoperative period suggested that three

[Precautions to be taken from the anesthesiologic point of view during venous surgery in the obese].

Numai utilizatorii înregistrați pot traduce articole

Certain precautions must be taken in venous surgery on the obese patient, as obesity is always accompanied by a number of particular pathological manifestations: haemodynamic disorders (breakdown of the functioning of the left ventricle and hypovolemia), or respiratory disorders (reduction of

A new challenge in pediatric obesity: pediatric hyperglycemic hyperosmolar syndrome.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To describe four adolescents with hyperglycemic hyperosmolar syndrome, an uncommon presentation of type 2 diabetes in pediatric patients. METHODS Case report. METHODS Two tertiary pediatric intensive care units in university teaching hospitals. METHODS Four obese adolescents with

Morbid obesity and optimization of preoperative fluid therapy.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Preoperative venous return (VR) optimization and adequate blood volume is essential in management of morbidly obese patients (MO) in order to avoid perioperative circulatory instability. In this study, all subjects underwent a preoperative 3-week preparation by rapid-weight-loss-diet

Standardization of the fully stapled laparoscopic Roux-en-Y gastric bypass for obesity reduces early immediate postoperative morbidity and mortality: a single center study on 2606 patients.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Various techniques of laparoscopic Roux-en-Y gastric bypass have been described. We completely standardized this procedure to minimize its sometimes substantial morbidity and mortality. This study describes our experience with the standardized fully stapled laparoscopic Roux-en-Y gastric

Bleeding from duodenal ulcer in a patient with bilio-pancreatic diversion.

Numai utilizatorii înregistrați pot traduce articole

Scopinaro's bilio-pancreatic diversion is considered as an acceptable malabsorptive surgical approach for the treatment of morbid obesity. We describe a case of acute recurrent gastro-intestinal bleeding in a patient with a previous Scopinaro's bilio-pancreatic diversion. At the first admission in

Real-time multimodal axillary vein imaging enhances the safety and efficacy of axillary vein catheterization in neurosurgical intensive care patients.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Controversy exists regarding the increased safety profile when ultrasound is used for central venous catheters inserted in the subclavian or axillary vein. The critically ill neurosurgical patient presents unique considerations for the optimal central line approach. METHODS This report is

The effect of somatostatin on dumping after gastric surgery: a preliminary report.

Numai utilizatorii înregistrați pot traduce articole

Many of the features of the dumping syndrome may be manifestations of hypovolemia and mechanical distension of the gut, resulting from abnormal fluid secretion in the upper gastrointestinal tract. The object of the present study was to assess the effect of somatostatin, an inhibitor of upper

Ultrasonographic measurement of the subclavian vein diameter for assessment of intravascular volume status in patients undergoing gastrointestinal surgery: comparison with central venous pressure.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Previous studies have demonstrated that ultrasonographic measurement of the inferior vena cava diameter is a useful tool for the evaluation of intravascular volume status in preoperative patients. However, ultrasonographic measurement of inferior vena cava diameter could be limited by

Risk of pulmonary complications in surgical patients.

Numai utilizatorii înregistrați pot traduce articole

The pulmonary complications in a group of more than 20 000 surgical patients between 1971 and 1980 were examined, as well as the pulmonary state of 100 surgical patients who died within 10 days of operation. The factors related to the patient's constitutions, nature of the surgical disease,

[Vancomycin nephrotoxicity: Frequency and mechanistic aspects].

Numai utilizatorii înregistrați pot traduce articole

Vancomycin, discovered in 1953 and widely used today, has a nephrotoxic potential that has long been debated. The frequency of renal involvement is variable and can range from 5% to 30% depending concomitant risk factors: overdose, chronic kidney disease, obesity, hypovolemia, and use of other
