Pre Surgery

What should I expect on the day of surgery?

  • You usually arrive at the hospital the morning of the operation.

  • A qualified medical staff member will typically place a small needle or catheter into your vein to dispense medication during the surgery. Often pre-operative medications, such as antibiotics, may be given.


  • Your anaesthesia will last during and up to several hours following surgery.


  • Following the operation, you will be taken to the recovery room and remain there until you are fully awake.


  • Post surgery, some patients may go home on the same day, while others may need admission for a day or more. The need to stay in the hospital will be determined according to the extent of the operative procedure and your general health.


Post Surgery


What should I expect after surgery?


Based on the type of surgery, seriousness of the condition and general health, you will be allowed to have fluids to drink the same day and soft diet either on the same or following day. In some circumstances, these will have to be delayed.


  • You will need strong pain killers for the first two days and milder pain killers for the next 5 to 7 days.


  • You will be walking in the ward the same day or the following day and will be able to use the toilet.


  • You can have a shower the following day.

The perception of pain is a common reason why patients see their physicians.

Pain is also an important concern after surgery.


Treatment of Post-Operative (Post Surgical) Pain

Over the past two decades there has been a significant improvement in the treatment of pain after surgery.

Most patients are provided with excellent pain relief after surgery and experience only minimal discomfort. 


Good management of postoperative pain is very important not only for comfort reasons, but also to encourage the patient to carry out chest physiotherapy exercises such as utilizing the incentive spirometer to prevent post operative pneumonia and collapse of the lung that is otherwise common with a large abdominal incision that are often made for big operations on the pancreas and the liver.

Post Surgical Pain Control Techniques


The following techniques are utilized for control of post-surgical pain


  • Patient controlled analgesia (PCA)

    • In this technique the patient uses an infusion pump that contains morphine or morphine type of narcotic pain medication. The pump provides a small continuous dose of pain medication to the patient. In addition to that the patient can inject him/her self with an additional doses of pain medication to control the pain. This is an excellent technique for the management of post-operative pain and the vast majority of patients obtain satisfactory pain relief with this technique.


  • Epidural catheter

    • In selected patients an epidural catheter is placed and pain medication is delivered around the spinal nerves as they come out of the spinal cord. This type of treatment is similar to that used during labor and delivery by many obstetricians. This technique also provides excellent pain relief from postoperative pain and is an alternative to patient controlled analgesia.


  • Oral pain medications

    • A variety of oral pain medications are available that provide the transition from intravenous pain medication to oral pain medication.
