The thought of having a major surgery may be terrifying. The patient’s life is always at risk upon undergoing any major surgery. Although surgery can be successful, all surgical procedures come with a risk of complications. Between one to three days after the procedure, complications are usually felt by the patients.
Found below are some of the common post-surgical complications:

• Pain: Patients commonly feel pain after the surgery. The degree on the invasiveness of the procedure may play a role on the intensity of the pain. Patient who had undergone minimally invasive surgery have speedy recovery from pain.
• Bleeding: Surgical cuts always results to bleeding. Blood loss in patient is minimum but in relatively long surgical processes, the total blood loss at the end of the surgery may add up. A blood transfusion is necessary for surgical patients with anemia before they undergo the procedure.
• Infection: Despite following preventive measures, the patient is always at risk for the development of infection. However, infection can be prevented using antibiotics.
• Blood Clots: The risk of blood clots forming in the leg is greater in smokers, obese, and immobile patients. The moment when these clots move into the lungs, the patient is at risk for pulmonary embolism.
• Cardiovascular Risks: Older patients and those who have a heart condition have higher surgical risk. Surgeons always require pre-operative evaluation of patients for assessment of cardiovascular risk factors.
• Pulmonary Risks: The blood clots in the leg may rupture and stuck in the lung circulation (pulmonary embolism). However, this condition can be prevented by daily administration of heparin, a blood-thinning medication.

Anyhow, people began to choose a minimally invasive surgery, known as robotic surgery, to treat illnesses. However, the manufacturer of the device that is used in robotic surgery has received complaints saying they neglected informing patients and doctors alike of the potentially harmful complications brought about their product. Nerve damage and excessive bleeding have been pointed as two of the complications caused by robotic surgery. A patient can tell if there is something wrong by watching the signs and symptoms of too much blood loss. Before undergoing a robotic surgery, FDA tells patients to talk to their respective doctor in order to determine if da Vinci is the best surgical procedure for them.
