How does obesity affect surgery?

Obese patients who undergo surgery are at greater risk for surgical site infection and slower healing because of reduced blood flow in fat tissue. In addition, many obese patients have diabetes, which also increases the risk of post-surgical infections.

Can you have surgery if you are obese?

Obesity can make surgery more challenging. If you or a loved one are overweight or obese and planning to have surgery, you should be aware that excess weight can put you at risk for certain side effects and complications. These can result from the surgery itself, or from the anesthesia you may need during your surgery.

What BMI is too high for surgery?

A BMI over 25 is termed as being overweight and over 30 is termed as being obese. There can be a higher risk of surgical and anaesthetic complications if you have a BMI over 30. If you lose even 5 to 10% of your weight, this could reduce some of the risks associated with anaesthesia.

Why are obese patients at risk for airway obstruction during surgery?

Sleep apnea also can make it more difficult to regain consciousness and take a breath after surgery.

How does obesity affect intubation?

Incidence of difficult intubation in obese is 11% and 7% in lean. Obese patients are difficult to mask ventilate and slightly more difficult to intubate than lean patients but have no difference regarding laryngoscopy. Age >40 years and sternomental distance <12.5 cm are predictors of difficult intubation in obese.

How can I manage Anaesthesia in obese patients?

For any obese patient, the implementation of difficult intubation protocols and the use of protective ventilation (low tidal volume 6-8mL/kg of ideal body weight, moderate positive end-expiratory pressure of 10cmH20, recruitment manoeuvres in absence of contra-indications), with morphine sparing and semi-seated …
