Summary
Postoperative pain is mediated by different mechanisms at multiple neural sites. Thus,
multimodal analgesics can reduce the postoperative pain. Although Opioids are considered the
analgesics of choice to treat moderate to severe pain, their use carries the risk of side
effects and hyperalgesia. Multimodal analgesia can be achieved by combining different
analgesics and different methods of administration, to provide better analgesia
synergistically compared with conventional analgesia. Therefore,lower doses for each drug can
be provided with fewer overall side-effects obtained from individual compounds.
Recently, antidepressants such as duloxetine, a selective serotonin and norepinephrine
reuptake inhibitor (SSNRI), have accomplished pain relief in persistent and chronic pain as
in fibromyalgia, postherpetic neuralgia, diabetic neuropathy, osteoarthritis and
musculoskeletal pain. The analgesic effect of duloxetine is attributed to its ability to
enhance both serotonin and norepinephrine neurotransmission in descending inhibitory pain
pathways. Moreover, some studies have promoted its use to improve the quality of recovery
after surgery and reduce the acute postoperative pain after knee replacement surgery ,
mastectomy , hysterectomy , and after spine surgery. In addition it can improve postoperative
quality of recovery through mood improvement that can be helpful in the postoperative period.
The main objective of the present study was to examine perioperativelythe analgesic efficacy
with the combination of duloxetine and prgabalinon postoperative pain when given as part of a
multimodal pain strategy in patients undergoing surgery on liosuction. In addition to
evaluating the patient's satisfaction and the adverse effects related to the combination of
both medications.
