 After surgery it is normal to experience some pain at the site of operation. In order to reduce the pain, medication such as Morphine is injected into a vein using a Patient Controlled Analgesia PCA pump that is kept at bed side, and is activated by the patient when needed. However, Morphine is an opioid drug, which can cause side effects such as sedation, nausea, vomiting, and reduced breathing on prolonged use. In addition to the opioid drugs, local anesthetics, and other drugs called Non steroidal anti inflammatory drugs NSAIDs have been injected locally to provide prolonged pain relief without the side effects of morphine. Recently a portable device called ON-Q pump has been developed to continuously infuse the local anesthetic through 2 small catheters inserted at the wound site. The ON-Q Pump is a small tennis ball sized unit made of a soft synthetic material that slowly infuses the drug through the catheters by elastic force. This pump is very safe and is attached to a bedside pole or the patients hospital gown. This pump has already been approved by the FDA for clinical use, and has been reported to provide effective pain management after some surgical procedures.
