7. Inguinal Hernia Repair | 69<br />

Iliohypogastric and Ilioinguinal Nerve Block<br />

Inguinal hernia is <strong>the</strong> type of surgery in which <strong>the</strong> IIB has been<br />

mostly practiced and studied. The IIB has been associated to<br />

monitored anes<strong>the</strong>sia care, general anes<strong>the</strong>sia or spinal<br />

anes<strong>the</strong>sia to decrease <strong>the</strong> initial pain after inguinal<br />

herniorrhaphy (Song 2000, Ding 1995, Andersen 2002, Aasbo<br />

2002, Toivonen 2004, Toivonen 2001).<br />

A combined IIB toge<strong>the</strong>r with an infiltration procedure may<br />

provide improved intraoperative analgesia, decreased<br />

requirements <strong>for</strong> additional sedation and monitoring and<br />

increased patient acceptance (Andersen 2005, Kehlet 2005).<br />

Many results indicate that IIB should be always per<strong>for</strong>med after<br />

a general or spinal anes<strong>the</strong>sia. Moreover, preemptive IIB may be<br />

effective in decreasing postoperative analgesic requirements and<br />

prolonging <strong>the</strong> time to first rescue analgesia (Ong 2005).<br />

Ropivacaine <strong>for</strong> IFB and IIB under propofol and opioid<br />

analgo-sedation compared to general anes<strong>the</strong>sia with wound<br />

infiltration, resulted in a significantly more rapid transfer to <strong>the</strong><br />

recovery unit and discharge, less need of analgesics during <strong>the</strong><br />

first postoperative week and significantly faster and less painful<br />

reappraisal of normal activities (Aasbo 2002).<br />

The adding of IIB improves pain relief <strong>for</strong> 4 to 24 hours and<br />

reduces analgesic consumption compared to spinal and general<br />

anes<strong>the</strong>sia alone (Tverskoy 1990). Patients require <strong>the</strong> first<br />

opioid or non-steroid analgesic rescue significantly later and<br />

start to eat and mobilize sooner (Nehra 1995, Abad-Torrent 1997,<br />

Bugedo 1990). These benefits occur in spite of pain score<br />

differences at rest or in movement (Harrison 1994). The<br />

beneficial effects of IFB/LIA on pain scores, analgesic<br />

consumption and return to normal activities may last <strong>for</strong> 6 hours<br />

to up to 10 days (Narchi 1998, Murloy 1999, Bugedo 1990,<br />

Toivonen 2001).<br />

The factors contributing to delays in <strong>the</strong> time-to-home<br />

readiness include nausea, vomiting, inability to void, drowsiness,
