Analgesic Effect of Trigger Point Injection and EMLA for Shoulder Pain in Laparoscopic Hysterectomy
Analgesic Effect of Trigger Point Injection and EMLA for Shoulder Pain in Laparoscopic Hysterectomy
Laparoscopic operative procedures have revolutionized gynecological surgery. These have
 several advantages: a smaller and more cosmetic incision, reduced blood loss and shorter
 postoperative stay, which cuts down on hospital costs. However, postoperative pain continues
 to be one complication, which results in an unpleasant experience for the patient and at
 times causes a delayed discharge. Trigger point injection removes the pain developing point
 and block the pain signal. EMLA cream shows analgesic effect when being spread on the skin.
 An literature showed that patch of local anesthetics showed the effect of trigger point
 inject. The purpose of this study is to investigate the alleviation of shoulder pain,
 headache, abdominal pain, and back pain after trigger point injection or EMLA cream applying
 on shoulder in patients undergoing total laparoscopic hysterectomy.
