Effective postoperative pain control is an essential need of every surgical procedure Pain pathway has three components :A first order neurone (cell body in dorsal root ganglion) which transmits pain from a peripheral receptor to a second order neurone.A Second order neurone in the dorsal horn of the spinal cord, through axon and spinothalamic tract crosses the midline to reach thalamus where third neurone through internal capsule reaches to post central gyros. Enhanced recovery after surgery (ERAS) protocols introduced in 1997 are the pre operative care protocols that promote early post surgical recovery.The purpose of this to reduce post operative complications, patient discomfort and reduces the length of hospital stay.Persistent post surgical pain (PPP) has a incidence of up to 30-50% and has negative outcome of quality of life and negative burdens on individuals, family and society.

It has a half life of 4-6 hours.Tramadol is a centrally acting analgesic that has minimum respiratory depressant effect.It also prevents neural toxicity by preventing setonin and norephinephrine uptake in spinal cord. The most common side effect of this drug are Nausea, Vomiting, Headache, dizziness, itching and hot flushes. Fentanyl was one of a series of opioids synthesized in 1960. It is effective as opioid analgesia with enhanced analgesic activity and potency and lesser side effects than morphine.Fentanyl is a short acting opioid can be used as both intraoperative and postoperative analgesia and can be given intravenously. |
