Transversus Abdominis Plane (TAP) Block Laparoscopic Hysterectomy
The use of pre-operative TAP block will reduce pain after laparoscopic vaginal hysterectomy and improve quality of recovery.
The transversus abdominis plane (TAP) block involves the sensory nerve supply of the anterior -lateral abdominal wall where the T7-12 intercostal nerves, ilioinguinal, iliohypogastric and the lateral cutaneous branches of the dorsal rami of L1-3 are blocked with an injection of local anesthetic between the internal oblique abdominal muscle (IOAM) and the transverse abdominal muscle(TAM)(12).This technique allows sensory blockade of the anterolateral abdominal wall via local anesthetic deposition superficial to the transversus abdominis muscle. It was first described by McDonnell et al. as a landmark technique to provide analgesia for lower abdominal surgery (13).
Hebbart et al. subsequently described an ultrasound guided technique for the TAP block which they named posterior TAP block (14).The ultrasound allows identification of the external oblique abdominal muscles (EOAM) , IOAM and TAM. Previous studies about ultrasound -guided regional anesthetic techniques suggest improved block quality and safety, which is primarily due to direct visualization of the relevant anatomy, the tip of the needle, and the spread of the local anesthetics (15-19).
Clinical trials of the single shot posterior TAP block have shown a significant reduction in morphine consumption during the first 24-36 hours after surgery (20-23). More recently , El-dawlatly et al. demonstrated that ultrasound guided TAP block in patients undergoing laparoscopic cholecystectomy reduced perioperative opioid consumption by more than 50%(24).
This is the first study to evaluate the effect of TAP block in the quality of recovery in patients undergoing laparoscopic hysterectomy and may help the pathway to make this an outpatient procedure.

Autonomic Nerve Block
Interruption of sympathetic pathways, by local injection of an anesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block.
A nonsteroidal anti-inflammatory agent with potent analgesic and antiarthritic properties. It has been shown to be effective in the treatment of OSTEOARTHRITIS; RHEUMATOID ARTHRITIS; ankylosing SPONDYLITIS; and in the alleviation of postoperative pain (PAIN, POSTOPERATIVE).
Pain during the period after surgery.
A narcotic analgesic that can be used for the relief of most types of moderate to severe pain, including postoperative pain and the pain of labor. Prolonged use may lead to dependence of the morphine type; withdrawal symptoms appear more rapidly than with morphine and are of shorter duration.
Abdominal symptoms after removal of the GALLBLADDER. The common postoperative symptoms are often the same as those present before the operation, such as COLIC, bloating, NAUSEA, and VOMITING. There is pain on palpation of the right upper quadrant and sometimes JAUNDICE. The term is often used, inaccurately, to describe such postoperative symptoms not due to gallbladder removal.
