  • In addition, obesity-related cardiac changes such as increased left ventricular hypertrophy and direct myocardial infiltration may also alter renal perfusion Kaur J.

  • Being obese is associated with improved long-term survival, validating the obesity paradox. However, once the need for surgery is determined, having excess body fat may provide increased energy reserves during a period of stress and healing that are not available to lower-weight patients.

Continuous variables were compared by using analysis of variance or the Kruskal Wallis test.

The relation between BMI categories and long-term mortality was evaluated using multivariable Cox proportional hazard regression analysis.

First, as mentioned, patients who elective surgery after overweight have a far higher risk of developing heart disease in carciac first place, and an ounce or gram of prevention is a much more effective health strategy than a pound or kilogram of cure. First of all, excessive subcutaneous fat tissue predisposes these patients to impaired healing due to low regional perfusion and oxygen tension [ 20 ]. That leaves them with little in reserve to resist the stress of major surgery and the prolonged recovery period afterwards. BMC Anesthesiol 15, Abstract Background Obesity is generally believed to be a risk factor for the development of postoperative complications.

Valentijn 1Anton A. Discussion In this large sample of patients we found that obesity is a significant risk factor for surgical site infection, more surgical blood loss and a longer operation time, however these complications did not affect long-term survival.

Introduction

The obese had more concomitant diseases, increased risk of wound infection, greater intraoperative obesity and elective surgery after cardiac loss and a longer operation time. AH supervised data collection and ans, edited the manuscript. Improving the fitness of the population is one of the most important public health strategies for reducing heart disease and the need for heart surgery in the first place. However, once the need for surgery is determined, having excess body fat may provide increased energy reserves during a period of stress and healing that are not available to lower-weight patients. On the other hand, we found that being underweight is associated with increased mortality in hospital patients and increased health costs.

N Cardica J Med. Tjeertes 1Sanne S. Conclusion In conclusion, our findings suggest that a tendency to consider obesity as a major risk factor in general surgery is not justified. First of all, excessive subcutaneous fat tissue predisposes these patients to impaired healing due to low regional perfusion and oxygen tension [ 20 ]. Received : 20 October A chi-square test was used for all categorical variables. However, recent studies show that, except for wound infections, complication rates are not increased in this group of patients [ 8 — 10 ].

Pulmonary disease was defined as any illness of the lungs or respiratory system, surgedy as asthma, lung cancer, chronic infections, previous pulmonary embolisms, or chronic obstructive pulmonary disease COPD. Table 2 shows the use of cardiovascular and pulmonary medication at time of surgery. In the multivariable analysis, the interaction between preoperative renal failure and severe obesity was an important mortality prognostic factor hazard ratio: Guidelines for healthy weight.

Computer simulation of the effects of alterations in blood flows and body composition on thiopental pharmacokinetics in humans. These divergent conclusions perhaps stemmed from differences in AKI diagnostic criteria, differences in geographical regions of study, dissimilarities in patient inclusion criteria, and different adjustment for identified AKI risk factors.

The highest risk of complications was seen at caardiac extremes of BMI, meaning patients in the underweight and the morbidly obese categories. A total of patients were suitable for analysis, of which Kaplan-Meier survival curves were calculated to assess the relation between the BMI categories and 5-year survival and compared with a log-rank test. Continuous variables were compared by using analysis of variance or the Kruskal Wallis test.

Obesity is associated with a number of cardiovascular system comorbidities that may influence perioperative management and outcomes. Complications related to airway management is a major cause of morbidity and mortality related to anesthesia in the obese population.

This paradox shows an inverse relationship between body mass index and afted, with lower mortality rates among the overweight and mild obese and increased mortality rates in the underweight population.

There might be a bias in referral pattern, since patients with major comorbidities and the super obese are usually seen in a tertiary hospital. In order to study the association between different BMI categories and postoperative complications, univariable and multivariable logistic regression models were used. All potential confounders age, gender, surgical risk, type of anesthesia, ASA classification, diabetes, hypertension, pulmonary - cardiac - or cerebrovascular disease and the presence of a malignancy were entered in the multivariable model to ensure giving an unbiased as possible estimate in the regression models.
